Chris Robinson has a great project to build a handheld linux terminal using a PiTFT, PowerBoost 500, and other parts. A Raspberry Pi powers the device and provides a complete Linux environment that you can interact with like using a tiny little laptop. The case is built from portable hard drive enclosures which were modified to hold the components and give the build a nice clean look. Reminds me of the old Atari Portfolio and other 80’s handheld computers, nice work!
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.
