The instructions were easy enough to follow, given they are in Chinese! We get the two circuits working perfectly. Really impressed with this one, it works like a charm! Didn’t do any range testing or what not, I’m going to do this one again when my little people come to visit.

Silly Job Title: Chief Engineer. I am the Chief Engineer!

In this video we attach some alligator clips to a handful of AA battery holders. I was planning to use these for a Learning the Art of Electronics experiment that I didn’t understand, but now that I understand the problem a bit better I don’t want to go short-circuiting five AA batters… that would be a bad idea!

We use the METCAL PS-900 Soldering Station for soldering.

We use the MUIN Solder Fume Extractor to clear the air.

We use the EEVblog BM2257 Digital Multimeter for voltage and continuity testing.

We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.

We use the Plato Model 170 Wire Cutter to snip, snip, snip.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
