Suggested Add-ons

This Calculator Kit from Spikenzie Labs features a prominent, bright red LED screen, a laser cut acrylic case, and reverse raster laser etched buttons. The kit takes about an hour to assemble and is pre-programmed so it will work as soon as you finish soldering and insert the battery. The chip is loaded with the Arduino bootloader for hack-ability. The calculator looks great on any desk and the buttons have a tactile, "clicky" feel that's just plain addictive. It's a perfect way to bring some maker style to your cubicle, home office, or workshop!
