New Diodes, New Ideas. New Hackerspace?

After much frustrated testing, it turned out that my one measly $2 diode from Hong Kong was a piece of $#!T. Surprise, surprise.

So, I ordered a couple more. A couple more. I received three. Don’t know why. Don’t know if I paid for it, but I’m not complaining either way. All three appear to be in working condition, but have not been tested (on account of the lack of safety equipment.

I have also received a new diode driver which I’m going to try very hard not to burn out this time around. It seems better suited for the project anyway. Pictures coming soon.

Since I had some trouble with X-axis wobble, I think I’ll try something new. The carrier for the laser is a small piece of wood with a hole cut in it. The carrier runs along the rail through that hole. My plan is to have two rails, and two holes in the carrier which will be lined with brass tubing to prevent friction. If they had steel tubing in the right size at the hardware store, I would have gotten it. Ç’est la vie.

I believe that the two rails in combination with the drive belt will create a sort of stable triangle, preventing the carrier from moving too much. And if it does move, I’ll rig something up with a spring and some bearings.

Despite this winter being “unusually” warm, it’s still not fun working in an unheated basement at those temperatures. Now that it’s warmed up a bit, I’ll be down there more often.

 

And boy, will I be getting stuff done! There’s a new hackerspace in town…probably. There is definitely an interested group of people, and we are working on securing a physical space. We are also working on securing a name. I think we are leaning toward “R00T Cellar”. Expect to hear more soon.
