A quick project I threw together to demo an example of an RTOS. The RTOS is ChibiOS ported by Bill Greiman. The controller is a quick PD controller I quickly calculated based on my mathematical model (no fine tuning) (read more)
This instructable was a LONG time coming. I had come up with this idea a while ago, after hearing about the details behind some basic “speech jamming” anomalies that occur when people use intercom systems. Basically, the intercom would introduce an ever so slight delay to the output of the speaker, so you would end up hearing an echo. I had planned on making this many months ago, as I previously stated but I was going to try and go discrete, aka, use a micro-controller and attempt to program some sort of delay code. But alas, I never could figure it out.(read more)
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
