Silly Job Title: Grounding Genius. I am the Grounding Genius!

In this video we continue to work through our Maxitronix 30in1, today doing project #8: The Slow Motion Sunrise-Sunset Light. In this project we see how an electrolytic capacitor can control a Darlington pair.

We use the UNI-T UTi260B Thermal Imager to examine the thermal properties of the circuit (there’s not much to see).

We use the OWON XDM1041 Bench Multimeter for voltage and current measurements.

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

Silly Job Title: Systems Architect. I am the Systems Architect!

In this video we continue to work through our Maxitronix 30in1, today doing project #7: The Sunrise-Sunset Light. In this project we see how an electrolytic capacitor can control and NPN transistor. By varying the resistor and capacitor we can change the timings of the circuit.

We use the EEVblog BM2257 Digital Multimeter to measure current and voltage.

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