High Frequency Probing Techniques for Reverse Engineering
Probes have a significant effect on the signals you see on your scope at high speed, and you need to be particularly careful with the GND connector to avoid large ground loops which will distort you signals. Have a look at this informative video on the topic from mikeselectricstuff, showing how to capture some high speed output from an iPod nano.
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.
