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.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
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, TinyGO, or even use the Arduino IDE.
