We use the Rigol MSO5074 Mixed Signal Oscilloscope to monitor the changing voltage.

We use the EEVblog BM2257 Digital Multimeter to measure voltage.

We use the Fluke 17B+ Digital Multimeter to measure current.

We use the Multicomp Pro MP701033 Resistor Decade Box as our variable resistor.

We use the WilliamKlein Music Stand to hold our textbook.

We use the Carpenter Mechanical Pencil to make notes.

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

We use the FNIRSI SG-002 Signal Generator as our constant current source.

Silly Job Title: Maker of Videos. I am the Maker of Videos!

In this video we do the 13th project from the Maxitronix 30in1 Electronics Project Lab Kit: The Leaky Faucet.

Here are the timing measurements we took:

Capacitor Resistor Period
10 µF 470 kΩ 3.05, 3, 2.97, 3.03, 2.98
10 µF 100 kΩ 0.67, 0.6, 0.8
100 µF 100 kΩ 7.02, 7.02, 7.15
4.7 µF 100 kΩ 0.43, 0.35, 0.39
4.7 µF 470 kΩ 1.76, 1.5, 1.56

We use the Rigol MSO5074 Mixed Signal Oscilloscope to look for the oscillating signal.

We use the UNI-T UTi260B Thermal Imager to check the thermals (nothing interesting to report).

We use the Carpenter Mechanical Pencil to take our notes.

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