This is A&N Laboratory’s Tentaku Mechanical Calculator DIY Kit which I recently picked up from Switchkeys in Australia.

With two beefy seven-segment LED display modules and a tiny bit of circuitry, it makes calculating fun. My build is equipped with Glorious Pandas (non-lubed). I am planning on getting a Glorious PC Gaming Race GMMK Pro 75% Barebone keyboard and wanted to see how well Glorious Pandas thock before getting a full set of key switches.

Here’s a bit of circuitry, nice and simple.

Powered by 1x AAA battery, just don’t forget to remove it when it isn’t in use!

Obligatory 1337. The calculator has a six-digit display. So while I couldn’t fit 8008135 onto it…

I was able to get 80085 loaded in. It’s in black and white to be art. Loaded with class and certainly not tasteless.

Assembly was straightforward. A&N Laboratory’s build video above goes through the whole thing.

1337 with the alternate ENTER key. The keycaps installed are the Drop MT3 Black-on-White Keycap Set. I’ll be installing these onto my GMMK Pro. I must admit though the Drop ALT keyboard looks very nice… expensive, but nice. In other news, I’ve also been working on a device known as the YamPAD. More on that in a future post!
