Capcom Mini-er Cute-r Countercade!

<< < (3/3)

I finally solved my plexi forming problems by sandwiching the aforementioned between layers of silicone mats before setting it into the 3D printed forms! Pics to follow. Also, I spent a few hours today learning how to, and then creating, schems for a PCB that re-routes the rear USB to the front using a bottom hat that interfaces w/ the test pads on a pi5!

mikejkelley:
The PCBs arrived and look great but need some revisions and so Vs 1.1 are being manufactured as we speak. While I wait I thought I'd post the wiring diagram:



Fun fact, the previous countercade I built includes an unnecessary relay. AI had assumed I was using a CRT monitor and had suggest the relay to protect against in-rush. After realizing our mistake I was able to eliminate it in this build.

The USB breakout board works! The Vewlix Countercades I built and the Capcom Mini-Cute Countercades I'm building require Pi ports accessible from the back and a USB port accessible from the front for controls. Previously I had soldered USB wires straight to the USB test pads on the bottom of the board. That way of doing things, however, ran the risk of ruining the Pi 5 board (which have just jumped an extra $50 overnight). Additionally, for w/e reason, the ground would never take and needed to be wired to the bottom of the GPIO pins in every instance. Also also, mini-soldering isn't for everyone. So, I created this USB breakout board that bolts to the bottom of the board! The first few iterations failed because the pogo pins were off by literally two tenths of a millimeter. This one however works well! I'm actually surprised it works given how crazy the tolerances need to be. Unfortunately the screen printing is upside down because I'm very, very dumb. It will be fixed in the next iteration. An especial thanks to PCBWay for sponsoring this project and the upcoming video on the Cyberspacemanmike channel!




I'm just waiting on a micro-to-mini HDMI cable and I should be good to go!

Nice work as always :)

Have you thought about using a Dell or Hp thin client instead of the Pi, obviously larger in size but might still fit inside your case.

Built this a few years for a sense of scale :)

mikejkelley:
Yes! The yellow one will interface with the prototype for two player action, acting as a separate controller/duplicated display plugged into the blue one's Pi. But the for the pink version I hope to add in a PC and run fightcade 2 and maybe add a verification script. That way people who build these can choose to play against other Capcom Micro-Cute owners the way God intended; with 6 buttons, no macros.  ;D
