Silly Job Title: Cable Connector. I am the Cable Connector!

I got some feedback from a viewer about an old project: 1-Transistor Radio | Project 5/10 | Maxitronix 10in1 | Learning Electronics In The Lab With Jay Jay. The observation was that there was a discrepancy in the instructions. So in this video I redo the project to see if we can get the radio to work if we wire it the other way. Alas, we don’t, but it was worth a shot. Thanks @Panthraz for your suggestion!

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.
