Silly Job Title: Current Curator.
In this video we make our second false start on Learning the Art of Electronics.
I mention about Make: magazine.
The power electronics YouTuber I mention is @ElectrArc240.
We consider using the Maxitronix 300in1 Electronics Project Lab Kit to for our project but we end up settling for a smaller breadboard.
We use the UNI-T UTi260B Thermal Imager to investigate the thermal properties of our powered circuits.
We use the Fluke 17B+ Digital Multimeter to measure voltage and current.
We use the EEVblog BM2257 Digital Multimeter to measure voltage and current.
We use the EEVblog BM036 Digital Multimeter to measure current.
We use the Peak Electronic Design Atlas DCA75 Pro Semiconductor Analyzer to examine our diodes.
We use the ANENG AN-999S Bench Multimeter to measure current.
We use the Riden RD6006 Bench Power Supply to provide power for our experiments.
We use the Carpenter Mechanical Pencil for writing out notes.
We use the Hakko CHP 3C-SA Precision Tweezers for working with small components.

In this video we take a look at what arrived in the mail. Mostly loot from AliExpress but also some USB hubs from Amazon.
In the video I mention Goo Gone. The stuff I use is the Original Goo Gone. It’s really great stuff! I mostly use it for removing sticker goo after I’ve peeled a sticker off something.
In this video I learn about “rivet nuts”. The ones I got are these ones. There’s a video on YouTube that will give you the idea about how these things work and are used.
