Every question, curiousity and doubt anyone has ever had about Peltier cells seems to be addressed in this FAQ from Tellurex. I stumbled across it over the weekend, and yes … it’s marketting material, but there’s still a lot of good information in there if you want to keep your favorite that beverage nice and chilly, or scavanage free energy using a heat differential. If you didn’t know about Peltier cells, now’s a great time to look them up and figure out some fun things you can do with them (post the details below … I love these things)!
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.
