I think it is possible to turn the Siglent into a 1 mV 1 mA resolution semiconductor curve tracer with NI LabView. Would that be interesting to anyone? I had some problems connecting with the free eva...

I thought they needed a little bit more thermal head room, so I mounted them on these big 100x100 mm heat sinks.

They even included a spare ES121 gearbox ... maybe there's hope still for a brushless ES121?

And what is shown is not even perfect. I suspect that grains from the coarser lapping film got embedded in the epoxy at first and caused the scratch later. Will try again tomorrow and am hoping to fin...

I've accepted a boring USB charger because I needed one and the guy was nice 😑
Also I wanted some verification of my laser driver circuit before connecting anything expensive to it.

My first 'high current' design ever. Since they don't charge extra for excessive amounts of vias I thought I'd add a few more :)

How did it get so warm so suddenly? 2 days ago I had to wear gloves and scarf to walk the dogs and today we had to trespass on this "private property" to cool down.

Pretty cool and easy to use sensor in this one. I wonder if one can buy them in small quantities.
