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)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
