    DIY Open-source open-hardware TC/Variwatt mod (STM32 based)

    Since my DIY arduino mod has a lot of restrictions, i've choosed the STM32F373C8T6 MCU for my next one. This is my first project with the STM32 hardware, so it has some problems yet. But since it is open-source/open-hardware - everyone can make it better! The main repository (with PCB gerber...

    DIY arduino mini pro based mod with thermocontrol

    I've added oversampling (#define ADC_OVERSAMPLING) option to read ADC four times at every measure, so it is more stable now (temperature don't jump so much). Too bad it is not possible to read more times as ADC is slow and measure itself heats up coil too much. I guess, it would be much much...

    DIY arduino mini pro based mod with thermocontrol

    My goal was to make easy to build mod with thermocontrol. I've had few arduino mini pro, which has 4 analog inputs, so it was easy to use it. The mod works with two cells (2S) Li batteries, i've used one from RC model (25/35C 500 mAh Zippy compact). Theoretical power is restricted by main FET...
