I decided to replace the 5V Battery with a normal battery for mobile phones, a PCB for charging and a DC-DC Converter (to convert the 3,7V to 5V)
The tiny PCBs fit perfectly in the GameBoy case not needing much room. I also replaced the mini-amplifier (boy, this thing was crap!) with another (better) one so I can use an internal speaker too.
Also an new USB Hub is now inside the RaspBoy, because 2 of the 4 USB ports of the old one were not working (yes, it was my fault..)
So I disassembled the new one…
…and removed 3 of the 4 USB Cables. Then I soldered the USB Cable of the Teensy and the wireless-receiver to the USB-ports and put the Hub into the RaspBoy.
YES, a wireless Receiver!
I had an XBox360-wireless-USB-receiver which I don’t need anymore, so I disassembled it and….had no clue where to put that big PCB….
I cut away not needed Parts of the PCB (It is a little bit bigger than it has to be) and had luck:
It fits perfectly in the Cartridge slot of the GameBoy Case and even the connect button is accessible!
When its done the Raspboy, connected to an TV with HDMI is a nice retro-console with wireless-controllers – well, at least thats the plan…..
When I power the whole thing directly without the Battery the RaspBoy works perfectly (almost), but there is a problem with the new battery: The RaspBoy tries to boot, but then (after a split second) it does a reboot . Also the Screen powers off, and then back on…
Also the PCB of the Gameboy Buttons or (more likely) the Teensy did´nt like the hours of soldering on it: There is an extreme input-lag when controlling the Raspboy with the internal buttons. The Raspboy won’t boot when the wireless Keyboard and the Teensy are connected to the RaspBoy simultaneously too….
I´ll do a fresh install of the RetroPi software first before I order a new Teensy – maybe I screwed up one of the config files….
Thanks to attentive reader Hugo the Teensy is history. You don´t need that thing for using the GameBoy Buttons, because you can use the GPIO Pins of the RasPi! Read more in my next Post….
