Ever since seeing Scott Garner’s Raspberry Pi powered Beet Box, I’ve wanted to make my own variation. The good timing of receiving the ADABOX 004 at the same time my newly retired dad (and his woodworking knowledge and tools) had some spare time led to this: https://www.youtube.com/watch?v=ViIEhdIwKjU . I hope you enjoy it.
P.S. To get the MPR121 library to work on the ESP8266, you’ll need to comment out all the instances of “while(1);” as it is checking the connections, even though this code shouldn’t execute. Also, the tracks are being played with playFullFile and just trimmed to a short length in order to avoid more ESP8266 messiness I had such as wdt resets than can occur with startPlaying.
Adafruit Feather HUZZAH with ESP8266 WiFi: Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.
The MPR121 has support for only I2C, which can be implemented with nearly any microcontroller. You can select one of 4 addresses with the ADDR pin, for a total of 48 capacitive touch pads on one I2C 2-wire bus. Using this chip is a lot easier than doing the capacitive sensing with analog inputs: it handles all the filtering for you and can be configured for more/less sensitivity. (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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
