todo, DIY vending machine (countertop and oshw)

Like this, but with arduinos. and caffeine. and breadboards. and 1/64” drill bits. and nyancat-etched poptarts. Oh, and open source. And constructable for less than $600.

(I get to the whole build-my-own vending machine thing further down the page. Got a bit ADD).

Well, in other news, my 2.008 group did not fall over themselves to build a PoV yoyo. This is okay. I will just make one or two PoV (persistence of vision) yoyo’s manually then. (you, dear reader, have just been saved from a pages-long rant as I sulked over the last few days :P)

mmm, instant noodles. aww. I miss my old room.

Oh right, where was I?

Arduino vending machines. That’s right. Make a DIY “open-source hardware” vending machine. Not interested in the electronics of accepting money and such (although that’s what everybody leaps to help with that, despite me explicitly stating I’m more interested in the vending mechanism).

Research: — coin mechanism and spiral set? not sure what it vended
So they’re called “augers.”


Found! mcmaster-carr “Dry goods screw conveyors”
