I purchased an inexpensive snap-together acrylic case for my Raspberry Pi from a seller on eBay. Overall I was happy with the case, but although this case has holes for passive air circulation I noticed that after running the Pi in the case that some of the chips were running a bit warm (even with heat sinks installed). Since this Pi will be running a web server 24/7, I decided to design a new top which accommodates a small (quiet and low air flow) cooling fan.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
