Hey Bill,

I have this.  I can take to AGM Thursday if you're going?

I have about 100' of 28 gauge as well and I can bring that! I have more than enough to construct my foam cutting table!

Experiment #1 with getting a glass hemisphere from a lightbulb.

[David hamp-gonsalves]

Did you score the glass first? 

(very cool experiment)

No, just tried to get the wire tight. I can see one spot where it isn't tight on the glass. I think a purpose-built piece of PCB with two connections very close together would help too.

That's amazing. I've tried to cut bulbs before and that thin glass is so hard to work with.

Second attempt. https://youtu.be/BNoZ2a-c2Lo

I'm open to ideas on how to make the power connector work better. It has two problems:
1) The solder melted, so the wire sagged. I don't think it's expanding that much with the heat

2) Where the wire isn't touching the glass, it gets very hot, and in this case, melted. So it needs to be in contact with the glass everywhere.

I have no advice, but the result looks good!
