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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
