ESP32 wireless microphone adapter

Submitted by themaker

A friend who works in a stage production company shared that the current options for wireless microphone systems are both expensive and unsatisfactory. As a result, I took it upon myself to design a custom wireless microphone system that operates on Bluetooth technology.

To use the device, it needs to be connected to one of the microphone boxes. The system then establishes a HFP gateway, enabling it to relay incoming audio from the microphone to a wireless headset via Bluetooth, and receive audio from the headset via the connected device.

Tiny esp8266 Gameboy

Submitted by themaker

I stumbled upon a gameboy emulator that was compatible with the esp8266, so I created a prototype on a breadboard to run it and built a handheld device. To get it to work with my new PCB, I made several firmware modifications. The final product turned out great!

Now, I'm working on resolving some issues with the custom PCB, but I'm confident that I'll have a fully functional system soon.

Tiger Handheld Doom

Submitted by themaker

I was inspired to bring a modern twist to the old Tiger handheld by using a more advanced processor. To showcase its capabilities, I decided to load Doom onto it.

After designing the printed circuit board and fine-tuning the firmware to work with it, I successfully brought my idea to life. The handheld works smoothly and is a fun homage to the classic game.

ESP32 S2 Gameboy

Submitted by themaker

Was looking to use up some of my parts I had laying around. And put together a Gameboy handheld using an esp32.

I put the SD card into a custom game cartridge. So you can easily load games to it. 

Also made a gameboy color version!
