The SpikenzieLabs Calculator Kit, is an electronics kit that makes a working pocket calculator that can add, subtract, multiply and divide.
The electronics is easy to solder through-hole parts.  Assembling the case is also part of the fun.  It is a handsome set of laser cut acrylic pieces.

The SpikenzieLabs Calculator Kit is another one of a kind, 100% original SpikenzieLabs kit.

Once assembled, this kit not only has the modern laser cut acrylic "wow", but a little bit of a throwback to the days before pocket calculators had LCD displays.  Six "Old school" 7-segment LED modules set in true SpikenzieLabs fashion.

Once the PCB is soldered, and the laser cut acrylic case is assembled, you will notice the buttons have an awesome click when pressed.  A fully functional six digit calculator that is as useful as it is attention grabbing.  Every maker should have one on their desks!

Put away that smartphone, it's time to use a real calculator again!
