Silly Job Title: Energy Maestro. I am the Energy Maestro!
In this video we do the 12th project from the Maxitronix 30in1 Electronics Project Lab Kit: Music from a Pencil.
We use the Rigol MSO5074 Mixed Signal Oscilloscope to investigate our oscillator’s waveform.
We use the METCAL PS-900 Soldering Station to solder our cables to the alligator clips.
We use the MUIN Solder Fume Extractor to clear the air.
We use the EEVblog BM2257 Digital Multimeter to measure resistance.
We use the Multicomp Pro MP701033 Resistor Decade Box as a variable resistor.
We use the Carpenter Mechanical Pencil to draw our pencil resistor.
We use the Plato Model 170 Wire Cutter to cut our cables.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
Thanks very much for watching! And please remember to hit like and subscribe! :)
p.s. today I added MUIN to my spell check.

Silly Job Title: Luminary Luminar. I am the Luminary Luminar!
In this video we continue to work our way through Learning the Art of Electronics. In this video we finish 1S Supplementary Notes: Resistors, Voltage, Current and do Exercise 1.10 from The Art of Electronics which has us investigating a voltage divider.
In this video I recommend to you the book Schaum’s Outline of Basic Circuit Analysis, 2nd Edition and Gary Tuttle’s website gtuttle.net where you can find Thevenin & Norton practice problems.
We use the METCAL PS-900 Soldering Station for soldering.
We use the AiXun H314 Hot Air Gun for heat shrinking.
We use the Pro’sKit SS-331H Desoldering Pump to fix up some of our mistakes.
We use the Tenma 72-10505 Bench Power Supply to provide 15 and 30 V DC to our circuits.
We use the EEVblog BM2257 Digital Multimeter to measure voltage.
We use the Fluke 17B+ Digital Multimeter to measure current.
We use eight of the cheapo Yum Cha DT830B Digital Multimeters as ammeters and voltmeters.
We use the Brother P-Touch D210 Label Maker to label our circuit.
We use the Sharp EL-546L Scientific Calculator to do some basic calculations.
We use the Bysameyee Head-Mounted Magnifier to light up our life.
We use the nmsafety Nitrile Gloves to protect our fingers.
We use the ElectroCookie PCB Prototype Solderable Breadboard to make our circuit on.
We use the WilliamKlein Music Stand to hold our tome.
We use the Scotch Titanium Scissors to snip, snip, snip.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to cut, cut, cut.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.

The Bang Preventer – aka DIY Current Limiter with isolation transformer
I asked Tony359 about his current limiter and he referred me to the video below in which he explains his home made contraption. Very cool. I think I should make one of these.
Update: I also found a video covering a similar topic:
The voltmeter used in the second design is this one: Digital AC Voltmeter.
Oh, and here’s another one!
Repairable USB-C port
These look great!
PCI Express over Fiber
This project is awesome! It’s what it says on the tin. The video also demos the use of ngscopeclient.
