For this one here’s an affordable (if low-res) Thermal Imaging project from a Raspberry Pi 2, a Pi Camera, a display(HDMI or PiTFT will do) and a Melexis MLX90621 16×4 thermopile array. Everything but the MLX can be had at #adafruit for around $125. The MLX90621 is available from Digikey for under $75. (In the video I call it an MLX90620. Ignore me, they are interchangeable with the 90621 having a faster refresh and lower noise.) (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, 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.
