New YM Synth board

So I respun the YM Synth, I didn’t try to cram in the layout this time so its quite larger.  I moved to a larger pic, and added some leds…. The new pic doesn’t require a crystal for USB so we dropped the crystal.  Unfortunately now I have to port over all the code.

Hmph.



Gameboy Color Pi Emu

Something I’ve wanted to do for a long time was make a handheld Gameboy emu.  It’s been done many times before.  For whatever reason recently I stumbled on XodusTech’s build, and felt really inspired by his set up so I started making one.  <grin>Oddly close to how they did theirs</grin>.  Here’s some pics.  So far some differences are I’m using a Gameboy color (instead of pocket).  It was what was cheap and broken on eBay.  Also I’m using a Pi model A instead of B.   I don’t need 2 USB ports or ethernet, and rather have the lower current consumption.  Also while I have plenty of Teensy’s around, I think I’m going to try using GPIO for my buttons instead of using the Teensy, shaves a few bucks off the BOM and lowers the current consumption even more.

It’s not quite done yet, I’m pretty close to finishing it.

Anyhoo, here’s some pics.
