I totally dont understand the point of the ruler part...i mean i guess its handy that random things have scales on them.

Off the top of my head: because it indicates it’s small size; so they can say it’s built into something; so it gives it a catchy name; because it sounds cool.

It doesn't just sound cool. It rules!

There used to be mechanical calculators that were rulers which were called "slide rules". Making a digital calculator with that form factor used to be an obvious thing.

I have a digirule 1. It's a fantastic teaching tool, great for seeing how large all the SMT package sizes are, and moderately -- but not completely -- useless as a ruler.

Too bad these are out of stock. I would love to get one.

There has been a trend of using PCB to make rulers for a long time. It's cheap, you can customize the message/graphics, it looks techy, and people love to collect them.

I have a Digirule and a Digirule 2a. They scratch many itches...neat gadget goblin, vintage computing goblin, buttons and flashy lights goblin, fidget goblin.

These are Altair 8800s for those who are curious but not curiou enough to click. Have LED outputs push button inputs and a usb connection to load/unload backup programs.

I've been eyeing digirule for a while me er pulling the trigger.

I do have several PCB rulers, the random high frequency pads are interesting.
