Bending Pins

I'm starting to work on getting the layers stacked, and the hardest part is getting the spacing correct.  I'm going to use little wooden pieces to separate the layers because my pins are a lot shorter than the ones from the instructions.  I've cut maybe 30 of them so far and I think I finally got the spacing right.

Now I have to bend all the pins over just a little so the layers can join.  To get the bend, I took a hardwood dowel and drilled the smallest hole I could into it a couple mm deep.  Then I put the layer back in the soldering jig and support the side of the wire with one of the spacing pieces.  I  put the dowel on the wire and bend in the direction I want.  It goes really fast because I put the hole as close to center I could which makes it easy to line up.

I'm bending all layers before I start soldering and while I have it in the jig, I'm retesting each LED to make sure its as bright as the others (or at least very close).  So far I've only found one dim one so I replaced it.

Still waiting on parts.  Some came today but no one was home and it has to be signed for so I'll have whatever that is tomorrow (I suspect it is the circuit boards).

After all the layers are soldered together I'm going to work on the USPtinyISP kit.

Haven't figure out what I'm going to mount the cube to yet, however, I am leaning towards mounting it in the template as soon as I clean it up a bit and maybe router out the bottom a little so the wires will poke through.

I will continue progress updates as I have them :)
