AvE Ruler

 
I received my AvE ruler kit in the mail last Friday.
The AvE guy is a YouTube cult-hero of sorts for DIY gearhead fabricator type people.
I’m slightly embarrassed to report that I am a devoted fan of his YouTube videos.
This little ruler, aside from measuring things, is a flashlight and requires a small amount of assembly.
The battery holder, switch, and LED light must be soldered onto the ruler body (which is actually made out of laminated circuit board material).
It’s a silly bit of geeky good fun.
