This is a micro controller based solution to build a capacitive input system for stuff like novelty video game controllers, as well as other stuff. Basically anything metal can be used as video game controller. Presently an stm32 development board is used, but effort has been refocused on creating a dedicated PCB. A possible version two of this project will use an STM32WB55 to do low power blue tooth with a host PC.
Initial development was done using a stm32 nucleo board. The final product will have a stm32F103 micro. I used a pre existing PCB with a similar micro to port the firmware over. Thankfully at this point it's mostly just copy and paste.
Did the boring part and put together a BOM on digikey, as well as an order on JLC pcb. All components should be arriving next week as of 2/28/2024. Very excited.
Today I posted my PCB design on Reddit in order to get feedback on my layout. I will also be working on porting the firmware to the STM32F103CBT6 micro controller, as well as component selection in order to have a working BOM.
