Stephen Smith ☛ Programming the SunFounder GalaxyRVR Mars Rover
Last time, we gave our initial review of the SunFounder GalaxyRVR Mars Rover, this time we’ll look at how to program it. Unlike SunFounder’s PiCar or PiDog which are powered by Raspberry Pis, the GalaxyRVR has an Arduino Uno as its brain. This means writing the program in Arduino C rather than Python. It also means writing to a lower level, since there isn’t any higher level library. The good news is that there are a number of good samples as well as Brett Hagman’s SoftPWM library to make controlling the motors easier.

Hackaday ☛ Sonolithography With The Raspberry Pi Pico
You can do some wild things with sound waves, such as annoy your neighbours or convince other road users to move out of your way. Or, if you get into sonolithography like [Oliver Child] has, you can make some wild patterns with ultrasound.
