Thanks to Eli for sending in this great DIY project! Read more about it here.
MonkeyJam will use the FRDM-K20D50 board (which has a Cortex M4 core with DSP instructions) along with the FRDM-JAM shield so you can make your very own guitar /bass stomp box. The end result will be a functional DSP system that will allow you to do high quality amplifier simulation and effects.
The FRDM-JAM does not limit you to DSP on musical instruments! There are 3.5mm stereo jacks to DSP filtering any type of audio signal. You could even use the USB interface to create a USB-MIDI Synthesizer! Lastly, no need to bring the house down….. a headphone amplifier circuit is provided so you can jam out without bothering the neighbors.
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.
