This project takes an existing tool — the Hakko FX-901 cordless soldering iron — and adds USB charging and a Lithium Ion battery inside a 3D-printed pack.
The FX-901 normally uses four AA cells, either alkaline or NiMH type. I like having this little iron around for cosplay electronics emergencies, and adding USB charging means there’s less to pack…it can use the same phone charger and USB cable I’m already traveling with. Less is good.
A fine little backup iron for anyone who does electronics outdoors…RC helicopters, ham radio, Burning Man, things like that.
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.
