Computer in a ruler

[karman]

I've found this in tindie and thougth it would be interesting to share it here:

https://www.tindie.com/products/bradsprojects/digirule2-the-8-bit-programmable-binary-ruler/

It's a ruler with a microchip emulating an 8bit computer. It has 8 addr leds, 8 data leds and 8 buttons to input manually data to the computer.

It's maker made a 32 asm words language and an excel to quick do programs by translating functions to its binary form.

Really nice to get in touch to computers like Altair 8800 and as a desk toy.
