Happy Birthday!

To Nate’s comment...
Wow, I’m now thinking of a smaller version I could inflate to do smaller jobs.
I’ve seen the popup ones they use for spray tanning, but there a bit too small.

A little bit of playing with some options/config on the bias supply and we got it down to 40mA draw on the batteries
Might be able to do a bit better still.
All in draw now is 260mA. We have some ideas on how to maybe bring this down a bit more.

Most of that is going to the supplies. The amp idles at almost nothing.

I couldn't stop listening to this yesterday
I was using my SR-007's. It drives them very nicely. Very rich deep bass and good imaging / sound stage, which is usually where the 007's suffer without the proper amp.
This was running this off of a bench supply at 11.1V and it was drawing .4A very consistently. The top board is the +/-300V supplies (with input EMI filtering) and the one below that is the bias supply set to 580V.
Each amp section is 1" x 2" and each of the +/- PS sections are 1" x 1". Bias is a little wider.

I'm looking for an HE90 jack. PM me if you have one to spare or know where I can order relatively quickly. I've been in touch with the manufacture, but it's going a bit slowly.
Thanks

I’ve been using fqpf8n80c with my miniature miniaturized (smaller than the group buy version) Golden reference supplies.
I also have the negative supply GRHV79 working in there too.
I always use the external current regulators now since they are much faster and actually protect the supply.
Works great. I’ve got a lot of hours on these.

I use HDPE for that stuff. I’ve always had problems working with delrin. It melts as you cut it.

I’m not sure if my setup can do thread milling, not sure if it’s a controller or spindle limitation.
Rough draft finished. Time to get some thicker cheap wood for a full mock up.
That’s very impressive!
Thread milling is more about the rigidity of the mill. At that size I’m not sure how well it would work, but it might be worth a try. I run my spindle at 12k rpm. Other than that it’s just a program/speeds/feed.

Yes. I got these two thread mills:
Took a bit of work to get the bit setup correctly in Fusion360, but works great now. When you're ready to try them, I can help you out.

Here’s an example of me milling some small brackets without having to worry about the outer contours

All this CNCing got me excited, so I figured I’d share...
Here’s my mill and this is a heat sink that I am thread milling. Very cool stuff
Also, I’ve been using painters tape and super glue instead of fixtures. Works great on metal. So much easier.
