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

More details

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" seven 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!

The calculator's controller can be re-programmed using the Arduino (IDE) programming environment.The following video shows the calculator activating a servo motor that in turns flips a switch on the Useless Machine.

Keying in a specific number on theCalculator (in this case 987410) activates the servo. This in turn flips the switch on the Useless Machine. The servo is connected via the programming port. 5V power to operate the Calculator and servo is provided by the white colour power bank in the center. The Useless Machine has its own internal battery.
