These are cool useful adult toys than can actually teach computer technology to the younger generation. They have that retro touch. I still have to program the new one but its fun for me.. I used to have to load a military computer called a AN/UYK-20. Now can relive the pain. Also similar running assembler cartridge on an Atari-400. The solder and masking is great.

I love my ruler 8>)

For Digirule - The Interactive Binary Ruler!

Really like the look of this, I work as a software dev and thought it looked fun. I bought two, one for my colleague at work, I knew he'd like it. Lots of fun, nerds love it and non-techies look at it (and us) and think we're stranger than ever!

If people think you're strange for having the Digirule, then my work here is done!

Pleasant surprise quick shipping

For Digirule - The Interactive Binary Ruler!

Bought one for an engineer friend. Very impressed with the level of technology and data crammed into 15 cm. One star for documentation as none was included. I had to Google to fine quick start guide. Very nice product but would it hurt to add a QR code for more info?

Hi Alan, glad to hear you like the Digirule :) there are links on the Digirule Tindie page for you to download the user manual, source code, bill of materials, schematic etc. This functionality is built in to every item page on Tindie but perhaps I should mention it at the very top of the Digirule page to avoid confusion.
