Got into a little bit of panic, because I promised to finish this SLA printer video by 28. Oct ... it's almost like friends birthdays for which you have an entire year to prepare but then they still m...

Second multimeter video with corrections
You may have already seen most of this. I have included a statement from Brymen at 3:09 and improved a few minor things especially after 6:10 and 7:25.
It's suprisingly hard to make the new mic soun...

Split the multimeter video into 2
Brymens manual soldering is still under investigation, so I've taken the BG one only and added another product to round it off. New stuff starts at around 4:05 min

Getting the super cheap 40W Chinese laser machine is probably the best starting point for a good machine. Tediously accumulating individual parts is neither cheap nor fast

Multimeter medley
Edit: Third revision - I am happy now with a few small corrections. Welectron hinted that the ugly manual soldering is unusual, I am still mentioning it, but shorter and with an optimistic connotation...

MUSTOOL MT8206: It works well as a beginner-DMM, the scope function still has some flaws! The comment with the most likes by next Friday wins!

Found a particularly nice NEMA-brushless-motor on eBay: 57BLF03
It's delivered with hall effect sensors, which are no good for precision motion control. The short shaft stub i...

Not quite as compact, but a few more independent voltage references AND a lot of unpopulated spots in this beast. It's basically a precision oven, that tries to stay at 30 +/-0.1 °C to keep the westo...

So this thing is supposed to become my OSMU controller? I am not quite convinced yet and am hoping to see some suggestions from smarter people in the comments :)
2018-09-18 20:47:35 +0000 UTC View PostThey didn't expect the LTZ1000
So the Schlumberger Solartron 7081 can only be calibrated via GPIB commands which neither me nor the Maker Faire stand had at hand, so we could only measure the voltage reference for now.
But one of...

The waveform display is no longer AC coupled, which makes it a little bit better. No more transistor tester and a slimmer body. Slow DMM sample rate, but attractive display.
They decided to keep the...
