Zombie's MintyPi

[ZombieKid164]

I finally completed my MintyPi build! I first ordered parts around October 2017 (when 2.0 parts came out) and have been finishing up the project over the last couple days. Before I show my build, I would like to give a HUGE thanks to Helder, as he helped me with some problems I was having during the build which I'll show further down in the post.

Wires:

(the one difference is I ended up having to wire my battery and sound card directly to the Pi's 5v because wiring them to the VCC pad through the PCB would not power the Pi.

I built it with a soldering iron without heat control, with hot glue and electrical tape (just to show it can be done without having kapton/double sided tape and a nice iron) although I did use both 26 and 30 gauge wire. I 3D-printed a hole guide (the rest of the parts I ordered from Wermy) and used that and a dremel to drill out the usb-charging port and power switch hole. I used a normal drill and small drillbits to get the L and R holes the right size. The only other change to the build I made was that I didn't wire the speaker to the PCB (I had problems with this) and instead I just wired it to the sound card.

There were three main problems I ran into throughout the build:
1) When I finally tested my screen, I found out it was broken! It had the issue where white bars appear vertically along the screen. Through some very light digging on the support forums, I found a post which Helder commented on telling the person to PM him to get a new screen. I PM'd him and got a response a couple days later. I sent back my broken screen and he sent me a new screen. This saved my build. Thanks Helder!

2) My second problem was that my buttons were really unresponsive. I found a post about this in the support section which showed one solution as adding a little extra solder to the button pads. I did this, and the buttons worked fine, but in the process I killed the ground connection to the screen, and with more help from Helder again I got this working by adding a jumper wire.

3) Since I had to wire the battery to the Pi instead of the PCB due to it not powering the Pi, I don't have a battery monitor. I still haven't figured this one out but I can live without it (Any suggestions are greatly appreciated!).

Overall, I had a fun time during this build and I learned a lot from it since it has been one of my first electronic projects. Huge thanks to Wermy for designing it and Helder for his PCB/Screen and help! Now all that's left is to play it, now that I've loaded it with games.

Nice looking build, congrats!

Not the end of the world if the battery monitor isn't working, sorry no good ideas for why that isn't working.

Nice work though, gotta love the clear 3d parts!

The monitor probably isn't working because it monitors the two power input pins for battery percentage, and you wired to the pi. Try connecting those pins to the spot where you're powering your pi too.
