Remove starlink trails:
I'd say, take some pictures shortly after, combine them and remove the starlink patterns.

Perhaps a similar approach would work for finding interesting objects.

bd139 would approve!

Not sure, if I should put it here or to the time nuts in the metrology section.

Speed gun physics explained:

I have 4 unused 470µF 200V caps ( Nichicon LGR2D471MELA35 ) with 10mm pin spacing, bought to swap out in the hp 8592L. The originals are however fine and these are currently surplus to me. Yours if you want them. Thanks for your kind offer! Sadly, those are ones with 10mm spacing but I need 7.5mm. ...

I'm really sorry.

I'll watch this with interest. I suppose it would be indelicate to ask how much it costs. The parts from Mr. Weigl so far: around 770.- Euro (2nd PIC controller included which costs 10 Euro). For the other parts my estimation is somewhere in the range of 600 to 750 Euro, depending on the source and...

Hello, some time ago, this 3-channel PSU from Rohde & Schwarz appeared on my doorsteps. It is a NGL 20 from around 1974. Every channel is capable of doing 0 to 20V and 0 to 600mA. This is ideal for tinkering around with OpAmp circuits. It is heavy for its size, the case is made of 1mm steel so v...

Same here, believe me!

Hello, this week a parcel from Mr. Weigl arrived here. It contained some special parts for his RoeTest device. Mr. Weigl has designed a nice and sophisticated vacuum tube tester with lots of capabilities to test and measure vacuum tubes. This is his project page with some assembly reports available:...
