Maverick (Nerf) Mod: custom blaster build log

blaster1_buildPics--008

Looking to do a Nerf gun mod... wanted to get some feedback on how to paint/weather it..

found a few projects on-line that I thought we pretty decent.. trying to decide on my own direction here.

1.) black & silver based (techy) theme

2.) heavy metal/blade runner feel (really digging this one and the wooden/brown handle on it)

3.) Army green & black style:

4.) silver & black (mas effect I think? not a gamer).. really like this style too.. even the logo (of some kind) looks right

5.) mixture, black, silver & brown grip..

Secondly.. a few other questions.. ;)

1.) how important (cool points?) is that the nerf gun still works as a nerf gun? Ive been thinking of removing the working 'dart' aspect of it.. in favor of some electronics goodness instead?? thoughts?

2.) anyone else have a blaster project in the works??

-----------------------------[update after some work]--------------------------------

update.....

after some work.. I made some progress on this project. ;)

I got the electronics all figured out.. (including making/baking/assembling the board, writing/finalizing the code, home brew/etching two additional custom pcb's...yadda yadda)

It is powered by S.C.A.B... :)
[kinda my generic/general platform for props..so far I love it]

I think I had posted pics of making my board somewhere before.. (in another thread currently running about)..

here it was it looks like:

here it is on the left next to an Arduino board (with a WaveShield stacked on top of it for comparison)

(fonts changeable on SD card, reads/loads a few defaults off a text file on SD card as well to set a few parameters on the blaster)

*safety = if on.. you need to have the trigger pressed when you boot up

*maxammo = total ammo count before having to reload

*acolor = led color when in auto-fire mode (can be r, b, or g)

*acolor = led color when in semi/manual fire mode (can be r, b, or g)

here is the first video of stage/phase one of the electronics and code development stage of it:

Prepping the nerf gun: (in no particular order)

*I needed a motor.. but didnt really know how I was gonna make it all work.. about torque on motors...sizes..etc..
got lucky and scored a motor that looked like it would fit from my local science surplus store.. biggest I could find that was small enough to still fit..lol (it seemed like it was MADE for the gun once I got it home)

*I knew I need to somehow get some leds into the barrel.. and wanted to have it be RGB..

*Wanted it to reload by pulling the slide on top back

*Since its a blaster the SD card and batteries needed to be accessible without having to open the the gun up (ie: accessible sd card and re-charge port)

*Needed to account for a switch/button to switch from semi/manual firing mode to auto-firing mode

here was my first mock up for testing space and how I was gonna attempt things: (pre dynamic default loading)

(s.c.a.b. in grip/butt)

motor:
after taking apart the Maverick gun (many tutorials all over on it if needed).. I saw how the barrel was turned internally by trigger pull.. and figured Id hack/modify it to suit my needs.
I cut/sanded the hexed shaped top off the post/part that connected to the barrel and turned a little inner sleeve and press fit hole so it would attach to the cut down motor shaft.

before/after motors:

** what you dont see pictured is any pics of the custom PCB I etched for the components to drive the motor (SCAB/Arduino do not have enough power itself to drive high power devices.. so you need a driver/transistor...etc.. something to help out)

but here are the shcematic and pcb files I made in eagle for it:

[img width=568 height=768]http://dmstudios.net/misc/motor_pcb/motor_pcb_2.jpg" />

RGB barrel LED:

I was going to use a DX RGB led star I had laying around.. but then decided it was over kill for a blaster (not like I need to light up a poly tube/blade or anything)..
so I opted for a 505 RGB led,.

*created a custom home etched pcb for it
*turned down a two piece optics holder and pcb 'presser up againster' unit to hold everything.. (similar to Ace's small OD optics/holders... but mine are much more shitty and crude..and no threading....well you get the point).. haha..

I wont go into detail on how I etched.. I have posted a few tutorials stp-by-step on how to make these at home in 10 minutes enough..

after etching.. smear some solder paste.. and populate board with resistors & 505 RGB:

bake it in toaster oven:

make inner sleeve/bottom portion to hold/push the pcb with (incuding some milled out section for wire passing)

make outter sleeve to hold optics in it.. and also has the bottom portion slide in and sandwhich the pcb up against the optics......and fits in the Maverick gun plastic barrel part:

Unit all put together:

Inside the Maverick barrel:

Exploded view of all parts/optics/pcb..etc:

Switches:

Mode select switch.. had to think about where I was gonna put this.. without some huge, ugly slider switch somewhere.. that looked like an after-thought...
I eventually decided to re-purpose the same button/area that used to allow the barrel to swing out and reload the darts..
*(this switch has an led in it.. I am nto currently using it.. but could be used to have the switch backlit.. I have a 3.3v pad on the board)

using a simple lever switch.. for both both main trigger and reload..

reload switch:
this one is secured to some perfboard cut to snug fit for inside the gun area.. it positions it in the correct place so the top slide hits it when pulled back, w/o mod to the top slide area/parts

main trigger:
you can see where I placed it int he above overview shot of the gun layout..

I mod'd/filed down the trigger a bit to hold the lever from the switch it in easier...(works great!)

after getting all this work and aligning things up.. I did a quick mock-up and cram-fu test with it mostly assembled.. (some parts have to wait for final paint and/or assembly)..

I took this video of its current state.. which Im calling 'done'.. and ready for break down and final paint & weathering (attempts) lol

thanks for the poll/feedback..

Im still not sure about trying a chrome/silver/nickle base and some dark washes.. or going with a black base..and trying to silver/grey dry brushing..etc.

(better decide soon eh?) lol

PoC: Custom MHS heatsink pcb (for my Obi TPM)

Obi_switchMount_proto-009

was going to post this in the 'idea thread'.. but figured just make its own thread for it..

another step in my OBI TPM saga.. lol

trying to keep the size as accurate as 'I' can, and still having it be somewhat MHS based at the core...
I was stuck on finding out a way to use the stock switches as real, functioning switches for my hilt.

(Ive always been keen on the all-in-one core ideas... but have the switches on/in the core and some sort of cap/plunger on the outside has always been a PITA for me... here and there a few ideas have came out/been used)

for the OBI.. when everything was done,.. the switch holes would go (more or less) at the same exact level of the MHS heatsink.. so I need to adjust that a bit.. and also find a way to mount some switches in that area..

I had mulled over Madcows switch approach. but just wasnt a good fit..

so I came up with a custom, round PCB, that mounts to the underside of the heatsink..and is secured using the same nylon screws that hold our luxeon star pcbs. (MHS hack!)

here is my prototype..

the bike valve switch will have an SMD led in it.. (like they normally do).. to light up the purple gem in the valve end. I just didnt put it back in yet..from doing the momentary mod to the switch (latching by default)

I also didnt clip the extra leads from the switches yet.. but I believe the idea is sound.. and can open up the doors for others to use the same idea/approach.. (nned to mount a unique switch?.. make a pcb for it!)

I posted a tut on how to etch your own pcbs..etc.. using your home laser printer and photopaper..

1.) make pcb deisgn in photoshop..
2.) print to photo paper
3.) iron to your copper clad board.

you get this:

etch and you are left with your laser printer traces (covering the copper underneath)

remove toner: (pcb is left)

Like Erv taught us.. pre-tin folks!

bend my switch leads underneath..and the other row down:

other switch:

on heatsink:

I dont have a red thumbscrew with the correct threads yet.. but you can see it mocked up there.. (screws right in from outside of hilt)

when heatsink is in MHS part.. it lines up with the holes perfectly.. (cant see it so good in pic_ =(

feedback always welcome..

hope this helps others get past road blocks in their projects!

thanks

S.C.A.B development…

flash_board

Over the 'years'.. (since I was first turned on to the RFX project/platform).. I fell in love with the idea of a generic platform for the user use as they saw fit.

motors, leds, rfid...whatever the project was.. a nice, simple, generic platform for users to 'tweak' and customize seems like a great idea to me.

with RFX basically defunct/dead... I turned toward the Arduino platform. Had a huge following, lots of examples.. and quite easy to get up to speed on basics..etc.. (even without an electronics background)

The problem with the Arduino platform (as is).. is that its purpose (to me) is for developing/prototyping your projects.. but not to be used in the end application.

why? due to size.. and price mainly for me.. (although other Arduino variants can come in smaller sizes.. the price is includes extra development stuff you may not use in your final projects...etc... and not to mention a minimal Arduino circuit can be made for under $7.00 bucks!)

And getting an Arduino to play audio isnt done easily (by default)..
****(although now I just tested a super easy PWM based audio output library.. doesnt use any DAC or AMP.. and the quality is pretty decent for what it is!)

SO I began to teach myself Eagle.. (not easy for me unfortunately..but after some time I got more comfortable with it)..

and laid out some stuff.. and finally felt confident enough to start making my own PCB's and having the shipped to me.. (instead of the old DIY home brew etch approach)

So here I am documenting my process.. (and failures) along the way.. ;)

a qcuik summary of the things I had to learn.do/involved..

*need to make a the schematic/circuit layout in Eagle
*hope its correct or have others look it over (check against design rules too)
*order the pcb's (sending the exported GERBER files form Eagle to your pcb fab house of choice)
*order a stencil (which is used to layover the pcb and smear solder paste over it to get it applied to the exposed pads through stencil)
*place parts on pcb (tweezers!!!!)
*re-flow pcb in oven

This was my first iteration.. using a different DAC than the schematic I was using as my guide:

Here was my FIRST generation of pcb's I got made:

Here is the pcb compared to other stuff.. an Arduino, a smaller minimal Arduino kit..and I think an US 2.5 board:

here I applied my solder paste.. and populated the board with its components..etc. and re-flowed in my wal-mart toaster oven!!

re-flowed:(done)

I had even tried to fix it by testing jumper wires to the default I/O pins..etc.. (no go)..

Well long story short.. after posting and asking....I just couldnt get it working with the DAC I had chosen..maybe someone else could have?? no clue.. (DOH.. should have just followed along..lesson learned)..which I guess is good.. as I had a few other mistakes as well.. =( SO I started over.

In the end, all I had was a tiny Arduino circuit..with on-board uSD socket.. nice.. but no audio output. :(

So lets go version 2!!

I got mew pcb's made... got a new stencil made..etc.. and started again.

Here is the process "I" did:

apply the solder paste, using stencil:

remove stencil.. examine paste placement on pads: doesnt need to be PERFECT as the heat from pads will pull solder towards it..etc:


Then populate board: (those TQFP chips are a PITA sometimes!!)

Stick it in the toaster for a bit.. (you can see the solder melt and get shiny)

and when you are done you get a finished board..

Here are some size shots and comparison shots against a full size Arduino & WaveShield (which is what my custom board is together..those two boards in one)



in the last pic you can see some pots wired inplace of some resistors.. I did this so I could dial in not only the volume.. but play with the filter/range, so things didnt sound so muddy/muted..

when done flash the board with whatever code you wrote to control/do whatever it is you need done.

thanks for looking.. was a fun project..

Custom 7-piece smd led bra graphs (and assembly)

smd_barGraph-013

From the JSSDC run Austin put together.. the bar graph pcbs..

blue is bottom layer.. red is top layer...

Here is link to the Eagle files too:

http://dmstudios.net/misc/led_barGraph_pcb/led_barGraph.zip

you can take those.. and export GERBER files for the fab house..

I already checked the design against the iTeadStudios design rules..and everything passed.. (so should be good to go)..

that being said.. it doesnt save us from ourselves! look at..study it.. make sure its 100% right..

walk yourself through the assembly and the application of using it in a build..etc.. see if you come up with any troublesome area...etc
I think one that fits/works in the MHS activation boxes would be nice.. same hole alignment..etc..etc.. some standoffs.. done.

if you choose to use the resistor pads on the CF.. bridge the pads on the bottom of course

suggestion.. if you plan on either offer built ones.. or making several of these for yourself..

invest in a stencil!.. (at least for the top [led] side)... its easier than you think to do... (costs a bit of extra money though)..

but saves time and produces a better 'finish' for your components/solder than doing it all by hand..

I have used both pololu.com and ohararp.com (I think thats the right name?)..

I preferred the later.. as it comes on a piece of KAPTON vs MYLAR.. and produced a better stencil (and Ryan was great to talk too.. very helpful for us noobs)

thats the nice thing about getting pro boards made.. you can use both sides to run traces way easier than a DIY board..LOL

----------------------------------------------------------------------------------

my attempt at assembly:

here are some pics of the board I just did this morning..

(summary)

1.) print out the pads/footprint from Eagle to a piece of paper..use exacto knife to cut out pads (ie: make your solder paste mask w/paper)

2.) align your pcb with enough, equal height stuff around it so the mask doesnt 'bow'..and you have a bigger surface to 'smear' against.
(I just use extra/leftover pcbs and stack along the sides)

3.) take your paper mask, and lay/secure it over your target pcb

4.) smear some solder paste at the top of the 'mask'... and grab a credit card or something like a putty knife.. and smear the solder paste over the mask

5.) for this type of PCB/project it doesnt have to be 'perfectly' aligned on the pads... (for fine pitch components.. I would wipe it off and start over)
you can see the alignment isnt perfect.... but it doesnt matter here.. also the heat will pull the solder toward the pads and even it out..etc

6.) after you apply your solder paste, you can populate the pcb with your leds (align/straighten as you see fit)

7.) throw it in your toaster oven...(tick tock)

8.) all done:

I didnt do the resistors.. if I was going to.. I would have started with that side first.. then done the leds last.. (or just did the resistors by hand.. as you dont see that side) ;)

all-in-all.. it took about 11 minutes to complete..

MHS [modified] control box (my entry in cram-fu)

controlBox_pcb_part3-010

been playing around with a few ideas over the years.. and have worked on a few control box ideas/projects as well...

this one is based off an MHS control box.. with some 'modifications' ;)

things to note:

*has two switches (main and aux) in it.. (one the 'side' of the box.. with custom switches and switch caps/stems
*custom PCB was created for them to mounted, to and mounted to the inside of the box.
*has a 1.3mm recharge port in it
* has custom smd led bar graph (custom made pcb for this as well)

pretty has everything a hilt needs, all located in the......... 'control box' ;)

posting my mock up pics... if things work out good.. (which it look sot be great even).. I'll break it down again.. re-fine...and buff/polish and powder coat for the finished product.

hopefully this gives some ideas for everyone else... make things work for you!.. make what you need...

lets begin:

1.) take your favorite drawing app and make a PCB design.. no special tools.. draw BLACK lines/traces and pads where you want 'copper' to be..
get your copper clad board/section..

2.) print out image on glossy photo paper.... iron/transfer image/toner to the copper board.. rinse under water to remove paper.. soak in etchant to remove exposed copper:

3.) after exposed copper is gone.... use a q-tip and some mail polish remover to remove the toner from the pcb... (revealing the copper/pcb under neath)

***(all this above has been posted many times before.. and shame on you for not trying it!... this could have saved your ass in that 'one' project!) =)

4.) mounted my modified switches to their PCB.. (these have the threaded tops on them for external switch caps to be used form outside the hilt.. keeping the main core/chassis/box internals standalone)
several solder pads depending on the need/space available


5.) mounted (mocked up) in the control box:

6.) (although it looks 'off' its really just the pic.. things line up great!)
side view of holes and where the switch tops are

7.) top (custom) pcb made..for the led bar graph.. (this posed a problem due to space.. and the fact that I wanted each led to be addressable for either all direct drive..'or' for CF led.txt sequence..etc.. not to mention trying to do double sided board without through hole plating.. (making my own)..

again.. space was concern.. (both sides)

I think an led (possible two) got ruined by heat? or something.. but Im going to replace them real quick. (as they only light up partially)

in the end it will be black box.. aluminum top plate and aluminum switches on the side of the box.

the top 'smd led bra graph' pcb/portion

this is where each resistors goes: (bottom of board)

quick mock up:
(again the switch pcb is in place already.. the custom pcb's are almost forming a box to support each other

---------------------------------------------------------------------------------------------------

got a couple hours the other night to finish 95% of it up... (I think 'real' professional PCB's would serve best here)

got the bottom half of the bar graph competed (resistors soldered, wires soldered..etc)

used 1206 resistors.. all I had at the time.. (yesterday my 0603's came.. had I had those in my plannign stage..I think everything might have been topside mounted....oh well v2 I guess..lol..this is my PoC)

still not quite sure how/where to tap the V++ to.. I have a few ideas...not a big deal though any place will work) ;)

quick test of being lit up.. (had to replace 2 leds as I think they were 'damaged' by initial placement? maybe soldering too hot? different bin? one was of color.. when lit up bright..then gradually died out after a few seconds)..anyways replaced them

2 x green
2 x yellow
3 x red

each resistored, each individually addressable... (so can be direct driven, used with CF, or as PLI) =)

quick mock up of the side/switch PCB inside the box. and the switches/caps/stems I made for them.. (still need to be shortened a bit..but they are close enough to work and show the effect/style)

more pics of the 'switch caps/stems'

the pcb's took about 30 minutes total to make.. (probably another 15 prior on trial and error on printing out paper copies and doing size checks)

now that I feel the idea is 'sound' I'll go back and plan it out a bit better.. (this is supposed to still have recharge port added..but Im not sure after implementing things this far it will make the cut)

time to break it down.. pc the control box BLACK..

buff/polish the 'switches'...

and complete the 'top'.. which is an already sized aluminum strip that sits flush like any normal 'card stock'

there is NOW window cut/milled out of it yet through for the bar graph.. =(

enjoy.

PoC: Expanding Hilt – Part I

expandingHilt_017

So I have been working on & off on an expanding saber..similar to the those hilts that have the exposable crystal chambers/core...etc

except this idea is NOT to reveal anything.. it is a step to make a more 'functional' (moving) type saber.. allowing for maybe smaller footprint (and concealment) into an expandable, longer hilt when needed/being used.

this is NOT finished.. and for those of you who have a problem with projects being posted while NOT completed.. simply fuck off. :|

Its in the R&D forum.. and I see people who do placeholder posts all the time.. so if you havent done anything like the above...then speak out.

anyways.. while developing/working on this.. I discovered several paths this could take.. and I also would like to get soem feedback on areas I am un-clear on how to proceed.

This is a long post.. outlining several of the ideas or variations that could be done.. and Im a long winded guy.. again.. if this a problem for you..

ALT + [F4] is a good choice for you right now.

Project goals/tasks or ideas that needed to be accepted or thrown out. (no order)..and to keep ideas out, posted for me to reflect on.

1.) smallest footprint when 'closed'..... (good idea.. nice small footprint).. but when open..what are you 'left' with as a saber?
grips both top and bottom? the extension piece?

2.) when open? form vs function... the function is there.. no doubt.. but when trying to keep/adhere to certain restrictions (like #1 above)..as well as make it visually pleasing.. it somewhat limits normal thinking/ideas.

3.) when closed..how to lock?
* I have a few locking ideas..each fairly unique..
* a outward 'clasp' (so to speak) that locks the top portion down/closed
* a 'threaded' end that is similar to sloth's reveal hilt.. the top section slides down..and can be turned/screwed into the bottom section.. (unscrew it expands..etc)
* a ballbearing/spring type lock.. Madcow used one on his hilts...as well as in use all over the world

4.) when open..how to keep from spinning/rotating.
* as of now..this doesnt need to be implemented.. BUT.. I have thought it out.. (will post pics/drawings really).. and is similiar to the sliding 'rail' chassis system I had been messing with a while back..and should work easy enough..

5.) movement/functionality
* how much movement is enough? or not enough?

there is a 3 way approach to the movement..

you slide the TOP section
you slide both 'core' * top sections
you secure top half..and make the 'code' slide (making the top section move as well of course)

so there is room for several variants..with different movement here as well..

to explain the parts/mechanics:

required:

2 x double male threaded connector (old style ones need to be modified... new version will need a custom part sleeve/shim (Super Mario Bros. Tunnel) for them to be compatible... I have used one of each for this demo/display)

a custom OD section of tubing (your sliding 'core').. with a LIP on the end..the same OD as a heatsink

1 x 1.25 OD spring (length to fit your project travel)

the rest of the MHS parts you use is up to you..and how much TRAVEL you want..or how you 'pull it all together'.. this is just the mechanics of getting an expandable hilt going..

this is (was) a WIP.. and if you dont like.. fuck off. ;)

re-cap:
if you dont like un-completed projects...dont have anything constructive to say.. move along. Im sure there is a conversions section somewhere.

could be a cool effect for a staff too.. double ended, expanding sides/pop-outs..

**(taking pics in a little bit)..

pic of the part(s) used.. you can see BOTH of the double ended male threaded connectors in use here..

the one with the threads left on was/is on purpose to try a certain 'locking approach'
if not using that route for locking..the threads would be turned down/off to mirror the other adapter/collar

you can see the collar/sleeve fix I had to make for the the lack of OG adapter part..and to be used with the new ID ones. (looks like a Super Mario bros. tunnel)..it slides inside the adapter (new version style)

spring and 'core' as well pictured.

fitment is great on all parts! (happy with it)



OG Double Male Threaded Adapter, that has been bored out..and the threads turned down: (reminds me of brass bastard a bit)..

and would look great for dressing a choke to a regular MHS part normally..not in conjunction with this sliding/expanding project

here it is one of the possible 'closed' states: (in this version since BOTH pieces have the external collars... the threads would be turned down.. to match the top collar..)


a better look at the 'core' (sliding system)



using the adapter..and leaving a lip on the core/tube..
I can screw it right into any MHS male part.. and effectively have a 'plunger' now.. the core tube will NOT come out. (not does it spin either surprisingly)

please excuse the super long-ness.. I have NOT committed to cutting the core/tube yet, until I am SURE on the levels of expansion and the locking portion of this project


rant:
(the longer the MHS part..the more travel, you can obviously get.... however that doesnt leave much for practicality in the visuals or the design.. since you dont really want a SUPER long, goose necked choke/core.. a nice 3 inches looks good visually ... but you also want the smallest footprint you can do when the saber is closed...unless its more for a quick effect or on a staff or something.... so that means shorter MHS parts.. and back to less travel then... however you can make both the top section..and the middle/core tube BOTH expand while holding the grip section) so you need to play with balance & direction a bit.

Locking approach #1:

forget the bottom 'collar'.. I have an internal 'ring' that supports the core/tube still.. but I leave the threads on the top collar..
collapse..and then spin the handle portion to lock into place?

un-screw...pop:

LOTS of paths I can take here.. with locking (hard part).. and choosing the expansion path more than one section expanding? or just one?..etc

cold here, not to mention time is absent alot these days... so like the bearing chassis pommel lock mod...figured Id just share what I have.. maybe it will help someone else.. (not to mention this one I could use some ideas on)

AoF Pommel (mod)

aof_mod-1

AoF Pommel (mod)

Got some pommels made from Randy a few (years?) back now...

they were oversized (OD).. because most MHS pommels were stock OD..

it is very similar to the Jay-Gon pommel #10 that is in production now..

I like them because:

a.) using a shroud/sleeve/overlay isnt BIGGER than the pommel OD now..

b.) it helps 'lock' in overlays because they cant slip past/over the pommel..

You can see an original one on the right...and the mod'd one on the left.

(some turning down..and trimmed up t-track)

on a hilt/extension section:

R&D: Proof of Concept bearing chassis/core mounts

breakDown-2

Being as its winter here..and I doubt I'll get in the garage much, anytime soon..
Wanted to post this idea/concept I had in my head..

while the pics are of a 'core/tube' type chassis this same concept could be used to an open 'sled' type chassis as well.

I talked about this with Fender a bit as well.. although the reverse sound one is not 'pictured'..

I think the idea is sound.. and this is just a roughed out idea..(including the cuts!!) :P

Im sure someone can tweak/fine tune.. find a better way. (in theory, a bearing wouldnt even need to be used..but makes it smoother)

Pros:
nice way to secure your core/chassis to your pommel for easy removal
no twisting wire problems

Cons:
mod'ing the speaker holder is PITA.. because the stock speaker OD is big.. I ruined s peaker mounted.. and that one pictured 'was ruined' but salvaged..lmao

in certain pommels, it wont work. (to close to end for insert)

not a lot of resonance

Together view: (not in pommel...but a possible end result could be)

Here is I have my 'core' (main tube) that can hold soundboard & batteries.. the top portion is just added from another past project.. (but is one possibility)..

that top part also have a bearing in it.. and can 'spin'

The 'main' part..(together)

The main part(s) (what is consists of)
turned 'stem' to fit bearing.. (can see similar in background)

Bearing got on stem..

I cut a piece of some external threaded tubing I had NPT 27 tpi I think?.. hollow..

that is actually press fit on there..and is not coming off.. but could be glued just as well little dab only..

it helps keep the bearing in/down... and the threaded part is used to secure the back of the MHS speaker mount.. (NPT 27 tpi tap...I'll have to look up exact size off hand)

the MHS speaker mount is turned to OD that fits INSIDE the pommel ID...easier to just bore out the pommel a bit though to be honest..save your speaker mounts from being wasted..lol.. hard to leave a 'wall' to snap the speaker into

there is a 'ring' with the ID of the bearing OD.. and the OD of a pommel ID

this slides over everything (stem, bearing, NPT secured threaded end)..and has hole tapped so set screw locks ring to bearing..

now you have your free spinning 'ring' that the pommel makes contact with..leaving the speaker/mount secure/non-moving

you get this:

the speaker side.. (see how its threaded through)... maybe dab of glue too?

alternate pommel (still works)

off-topic:
Here is the top portion.. (although a bit off topic)..notice similar 'stem/bearing' system..

but this time a top part goes over the bearing.. (set screw secured to bearing)..

and it spins the crystal, etc..

back on topic:

ok..so you take the whole thing..after you secure the 'bearing mount' to your core or chassis...etc..

and it slides into your pommel.

you can see the little drilled & tapped hole in the pommel.. un-obtrusive.. and it secure the pommel to the 'core'..make sure you secure it to the 'free spinning ring'.. and not the speaker mount..

side view:

feed back always appreciated,..

Im sure it can be improved upon...so thats why I shared it..LOL

maybe not for every build..but if the case calls for it..here is one solution to apply.

Thanks

Custom/MHS OBI-TPM (hybrid)

emitter_1

ok..so this has been on the burner.. for....well for a long time actually.. I sorted started it when I saw Obi-Dar posted his build start...

it was shelved.. as I didnt care for the route I was taking at that moment....

anyways did some more work on it.. and here is where I am at.. figured Id get some feedback..

I think it looks a bit 'weird' to me because there are no cut-outs in the shroud/emitter yet..(Im hoping thats all it is!..lol)

as far as being an 'exact dup' in dimensions.. its of course not.. (its no ACE OBI TPM to be sure, spot on with awesome machining) ;) .. 'but'..its not that far off from the dimensions I got on-line.... the most notable place is the main hilt 'OD'.. which will mostly be cut away so I dont think it will have that much effect on the final look... every thing else is exact or a not 'too bad'...

overall length is over 11".. but little under 11.5 if I recall..

feedback is appreciated of course. :) things/areas to work on.. (although its not complete of course).. or things that should be re-done perhaps?

Thanks.

(Im no photographer!)

The parts used:

1 x Ace Obi TPM pommel
2 x 1.5 sink tube adapters (turned down to be 1.39 OD and faced to be roughly over 1")
1 x 1.25 'core' aluminum tube so it has a 1.25 choke section ;) (slightly modified to meet ID of one of the adapters I used)
1 x MHS BH #3 turned down to be 1.39 OD)
1 x custom hilt shroud ID bored to 1.39...OD to match the TPM as best I could..
1 x custom shroud ring/support for the top end which has a bit larger OD and design
1 x custom emitter shroud ID bored to 1.39 (OD has a bit of a lip/larger OD than the rest for the 'top ring")
1 x custom 'ring' taking a cue from Randy/Obi-Dar's build of course.. (and because I fubar'd my 1 piece attempt the first go-around) (DOH!) :dft001:

All parts

Rings attached:

Top section:

Side:

Angle:

Full:

Last:

The OD of the ring needs to be opened up to 1" to accept a blade still.. but thats really only about 10 minutes of work to do..

if it passes the test(s).. then I'll work on the shrouds or something.. wire it up.. and see what board it gets (if any)..

if it goes over well.. I always have the 'rule of two' for builds.. and there is parts to make another :)

Thanks gang.

-------------------------[update II]------------------------------------

just some quick update shots:

got the 3 windows in the top emitter shroud and the window in the grip shroud cut out by Tim (great work too, thanks Tim)

bike value
some bezels
and the delrin 'grip section' and I can focus on internals..

not sure if it will be than board/battery pack etc...

not too much room for a chassis!

some pics.

(I think she is turning out very nice.. no "Erik/Ace" version!..lol.. but nice to me!) and not too fat/chubby.

the shroud and BH fit like a glove.... and Tim's window cutout make it look so nice.

I put the lines/grooves in just about the perfect spot with the BH and the modified adapter 'seam' makes it less noticeable

Heres a pic with the ring on and all together.. (pic isnt so great..its look nice in person.)

more pics of the sleeve I turned down..with slight dip/bevel that i sent to Tim to be cut out.

A pic with the sleeve and the 'collar/ring' for the 1.25 inner and sleeve connector/support. (this part is being re-done for better tolerance fit....that god its not a hard part at all!..)

Some side/full length views:

no delrin inner grip section.. just a 'temp' all black filler...lol

hopefully I'll get some free time to wrap up the hilt stuff.

Thanks

I have a couple more variations on the modular sections/parts..

appreciate all feedback...

specifically on things like:

switch mount/bucket
*standalone vs. part of heatsink bucket
*generic enough for all switch types or maybe 2-3 yes?

battery/sound/speaker bucket:
*size constraints? stuffed 2xAA sized batts and a US2.5 in there.. probably some room for wires..not much else? (not sure of CF would fit due to height.. maybe different battery solution?)
*make both speaker only bucket and attach battery/sound board to 'rods'? or other area? and the speaker/battery/sound bucket? or just the former/later? (maybe milling out some grooves in the bucket will help with space a bit?

heatisnk/led bucket:
*right now the led/heatisnk is part of the 'core'.. should it not be? shoudl there be an alternate 'modular' section you can choose as an 'end cap' to the core?..and then you just run wires from core to led, like in any other normal build?.. of course you would have to choose to either lock/secure the core using the speaker mount end 9liek in normal MHS builds using a pommel speaker mount...or an end cap/section that has the OD of the heatisnk..and using that approach to locking/securing the core to the hilt?

Eastern will be giving a review of his as well when he gets some time to play with it.... maybe covering some of the topics above .

Thanks
