This Saturday 4/2

We will be having a build day to work on our Global Hacker Space Challenge entry. Come and help us build components for our entry.

Chime in if you can come by and help, hope to see you there.

I'll try to swing by. Time?

Sorry,

starting at 1:00 until 4:00 was my thought.

Thanks to those who came and built. We made some good progress, and unfortunately I didn't take any pictures. We are working on getting some casting options going to mass produce little LEDs and I'm trying to get some models cut out to try and vacuum form the ATMega chip body.

Sorry I did not get a chance to help any, it was just a drive by day.

For the LED's are you just pouring acrylic resin into a mold with a regular LED and reflector in it. (think Ice-Cube size) The acrylic that is used for counter tops and what not is clear, so we could even color that to match the LED color and with Bright LED's and a single aluminum reflector they should work?

Anyways I will see what I can help with Wednesday.

Very much what I'm thinking, though we haven't seen a need for reflectors, here's what I proposed on the GHSC google group.
BTW if anyone is interested in tracking the Hacker Space Challenge details join the group.

I'm enamored of the idea of pouring little ice-cube trays full of 10x LEDs. I was thinking of just cutting a set of negatives in foam, but I think would be a bad choice to get them to release etc.

My latest thought is to carve a little forest of them in foam or mdf, then get flexible silicone mold making stuff, and pour it over the forest (which we cleverly leave a lip all the way around). So then we have a silicone ice cube tray thingy to pour something clear, maybe Easy Cast or the like in, prop the LEDs on little rods so the are at the right depth and let them set.

My biggest concern is attaching the giant wires to the little LED leads in a discrete way, tough to hide when it's all clear.
Well that and I found a very loose Z-axis lead nut, and no proper wrenches to fix it today.

So what are everyone's thoughts?

http://www.iasco-tesco.com/ has silicone stuff, and EasyCast we can get at Michael's etc

I posted some of my latest foam model cutting to the blog. Mike made some solid models of LEDs out of PVC and Steel spheres. Post some pictures Mike!

I think we'll want to do another build session post Faire, not sure when yet.
