Tiny Oscilloscope kit based on STM32F103 ARM microcontroller

I’ve still got some soldering skills lol. It comes in twoContinue reading “Tiny Oscilloscope kit based on STM32F103 ARM microcontroller”

Replacing white LED stylus target light on Audio-Technica AT-LP120X

Most of it is old/scrap components – only the 555 and the MC14526 counter/divider actually do anything – flashing the LEDs long the edge. I can remember making it at work during quiet times as a side project, IContinue reading “Flashing LEDs with a 555 timer – and not a lot else”
