Wireless Microphone Receiver Disassembly and Examination to Reduce ‘Hum’ Noise
If you’ve ever worked with wireless microphone and audio systems you will appreciate this video from Micah Scott. In it, a Pyle PDWM1940 wireless receiver is scrutinized and then opened up. In classic curiosity style nothing is what it seems at first, with an otherwise seemingly single-sided PCB with through-hole components containing an underside with some pretty intriguing circuitry that gets thoroughly deconstructed.
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.
