ParanoiaBox and NTSC libraries

Hello, I have designed and built the ParanoiaBox, a device for embedded encryption. You connect a keyboard, TV screen, and then you can compose and encrypt messages that are transferred using SD cards. You can find the software and hardware at https://github.com/profdc9/ParanoiaBox/ There are also N...

Do-it-yourself Bluepill PCB

Because of the proliferation of fakes of the STM32F103C8T6 going around, I made a PCB you can use if you want to roll your own. Of course, you could always buy a fake and lift swap the fake for a real part, but this board is made of more durable components. It uses very easily sourceable 0805 SMT pa...

My STM32 Bluepill projects

Since this is a new stm32duino, I thought I would talk about the projects I've developed, so far with Roger's core Theremin https://github.com/profdc9/MCTheremin A theremin that has both pitch and volume control and digitally synthesizes the audio signal using an external DAC (MCP4921). Vector Netwo...

Triggering DMA transfer using a Timer capture/compare

Hello, I am working on a TV output library for stm32duino (STM32F103CBT6 bluepill) for a project. The project is a monochrome character-based text output to a NTSC television (though it could probably be modified for PAL pretty easily). It is based on TNTSC https://github.com/Tamakichi/ArduinoSTM32_...
