Oh man. Everything’s broken and I don’t know what I’m doing. I have a NeoPixel LED strip which isn’t working right. I’m trying to debug the issue but am not having a good time of it.

Silly Job Title: Tech Lead. I am the Tech Lead!
In this video we continue to work our way through Learning the Art of Electronics. In this video we continue with 1L Lab: DC Circuits and measure the internal resistance of our meter movement.
We use the METCAL PS-900 Soldering Station for soldering.
We use the Pro’sKit SS-331H Desoldering Pump to desolder (unsuccessfully).
We use the Riden RD6006 Bench Power Supply to provide 1V power for testing.
We use the Fluke 17B+ Digital Multimeter to measure current/voltage/resistance.
We use the EEVblog BM2257 Digital Multimeter to measure current/voltage/resistance.
We use the Brother P-Touch D210 Label Maker to label our circuit.
We use the Sharp EL-546L Scientific Calculator to calculate our values.
We use the ElectroCookie PCB Prototype Solderable Breadboard to make our circuit on.
We use the Multicomp Pro MP701033 Resistor Decade Box to provide test resistances.
We use the WilliamKlein Music Stand to hold our textbook.
We use the Carpenter Mechanical Pencil to take notes.
We use the Hakko CHP 3C-SA Precision Tweezers for tweezering.
We use the Plato Model 170 Wire Cutter to cut wires and trim leads.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
The circuit I make in this video for interfacing the meter movement is JJ001:
