Computer History On a Breadboard: The MOS 6581 Sound Interface Device (SID)
One of the most famous sound chips of the 80s is undoubtedly the MOS 6581 Sound Interface Device, or SID for short. Let's put it on a breadboard and get some sounds out of it.

HOW T
how-to-automate-slot-cars-with-an
you want to race, but have nobody who wants to play with you? Then why don´t you race against an Arduino? In this video, I show you how to prepare a slot car racing track and write an Arduino sketch so that you always have somebody to race against. For this reason, I arranged hall sensors around the track that signal the Arduino, where the car actually is. The Arduino sketch then accelerates or brakes the car accordingly...

BREAD
breadboard-fm-radio-with-rda5807-and-wio
This is a complete FM receiver circuit based on the single chip receiver RDA5807. The WIO Terminal controls the chip over the I2C protocol and offers a nice user interface built on the LVGL library. It has a wide frequency range (50-108MHz) even outside the public FM broadcast channels, offers automatic scanning and RDS/RBDS.
