Nice build Veteran, it's very clean and promising.
Which battery are you using ?
Did you notice any heat problem or safety risk putting it under the screen pcb, pi3 and retro psu ?

@VeteranGamer,

I am LOVING your build and will try to emulate it myself. Question, what battery did you use? I too have ordered the same charging board you are using from Helder. Which by the way thank you that board is AWESOME!!! I have overlooked your latest picture and will try to trace your wiring from it. If you happen to find the time to throw together a diagram of just the charging/power circuit you have implemented I would be in your debt. As when the wires get down to the power button board I cant see all the wires and where they go at that point. Thanks in advance and everyone a part of this thread is amazing for pioneering this build.

Thanks....

I think your always gonna get heat problems with a RPi 3

However...

Nothing is touching the battery apart from the back of the screen....

All the components are raised up by a few mm with the aid of VHB...
I’ve also placed thermal pads under the RPi and the screens PCB (Just where necessary)

But it’s still gets warm (as expected from the RPi)
So I do plan on using a heat sink and a fan
(same fan as kite uses in his kits)
But I want to source a battery cover first...
As I want to put some venting in it and would like to have a spare just in case things don’t go to plan

The battery is just a 6000mah battery I found on AliExpress that fitted within the screen holder...
You can go for a larger capacity which will also fit..
But they are slightly thicker, and I wanted the thinner battery for the things I mentioned above..

Well veterangamer I cant send pm's. Not sure why but none of the pm's ive sent have gone through.
Anywho the new Teensy came in. I wired it up again but now its working slightly better then before but not completely. So the left analog stick wont recognize left or right in the button config of retro pi. Only up and down. Now the right analog sticks works 100%.

This is the code that ive been using for teensy. It matches the pin out guide on the first page so ive using that.

Im racking my brain cause i didnt do anything different but now the right analog sticks works but the left still only half works. I dont know where to go from here.

Well veterangamer I cant send pm's. Not sure why but none of the pm's ive sent have gone through.
Anywho the new Teensy came in. I wired it up again but now its working slightly better then before but not completely. So the left analog stick wont recognize left or right in the button config of retro pi. Only up and down. Now the right analog sticks works 100%.

This is the code that ive been using for teensy. It matches the pin out guide on the first page so ive using that.

Im racking my brain cause i didnt do anything different but now the right analog sticks works but the left still only half works. I dont know where to go from here.


If the script/code is tried and tested....
Then I doubt that it’s the script at fault...

I’m no specialist in coding so I can’t look at it and tell you anything....

But going on from my own experience...
I would check the continuity between all the functions and the teensy...
This should include
functions to 10 pin breakout
10 pin breakout to teensy
Functions to teensy

(But for the analog sticks obviously the wiring is the first thing you check)

I personally had to get things spot on to work...
Even thou initially to me (noob eyes) I thought I had it spot on....

Especially the 10 pin breakout...
As a slightly off ribbon cable will mess things up...
Or
A pin from the ribbon connector not making firm/solid contact....


NB: if you using one of the script/codes BanjoKazooie has posted, it definitely won’t be the script....

Checked all my connections and just resoldered everything making sure they were solidly melted and in place and it is all working now! Finally! Ill have this buttoned up and a picture of it soon. Thanks for your help and motivation VeteranGamer. Still cant believe I went through 2 of those Teensy boards....man was that not fun!

Well this have been one heck of an experience. I have a few small clean up spots to take care of on the inside but its done and working! Again Thanks to veterangamer and everyone here for all your help.

thats great news.....
where there's a will, there's a way


I would recommend/suggest making a build/show-off post....
there aren't that any of these builds on here...
and to also highlight your issues ad how you over came them....

it doesn't have to be super detailed....


great job any...
enjoy
