We're continuing on our quest to replace the brains of the Baby Einstein Take-a-Long Tunes toy with something that can play Autechre or Bjork. Since the last video, Mr Ladyada has scanned in the PCB so that we can start to trace the outlines. We used simple computer image editing software to delete the background, rotate it so its straight, and convert it to monochrome. After importing, we traced out the slots and holes so that our new PCB will be able to fit right in place. Now its time to spec some parts! Our big decision is what chipset to go with: we can't get SAMD21 or SAMD51's anymore, so our best bet is ESP32 series or RP2040. Since the case does not have a USB slot we have to have the USB port for programming on the inside and a few screws removed to do so. So we figured a WiFi-capable chip would be nice since then it could be programmed wirelessly. So we're gonna start with trying to place an ESP32-S2 (https://www.adafruit.com/?q=esp32-s2&sort=BestMatch) inside. For audio output we'll use the MAX98357 mono I2S amp (https://www.adafruit.com/product/3006) since the DAC on the -S2 isn't very good for audio playback. Now we just have to fit it all in and route the PCB!
