The SpikenzieLabs Calculator Kit another one of a kind, 100% original SpikenzieLabs' kit. Easy to solder with through hole parts that it is both useful and super cool! Comes as a kit of electronic and plastic parts, after it is assembled you will have a lovely battery-powered pocket calculator. If you're feeling extra-adventurous, the chip is programmed with an Arduino-compatible bootloader so it's very hackable as well. Some tools are required to assemble: soldering iron, solder, and wire cutters. You'll also want some masking tape and a hex wrench (although we just used pliers assemble the screws)Features:
