DIY Bench Power Supply #9 - Transistors under load and adjustment with Pots

In this video I test the newly mounted power transistors on the heatsink. I show what kind of adjustment you can have with various potentiometers.
The circuit does have an issue with oscillations which I will cover in the next PSU video.

DIY Bench Power Supply #8 - Mounting Transistors on the Heatsink

In this video I go through the process of mounting the 2N3055 (TO-3) and the BD140 (TO-126) transistors to a heatsink. This is in preparation for testing the power supply under load.

Some parts for this project from my Amazon Store:

#191: Beware of test equipment loading effects!! Learn from my error!

In the previous video, #190: Transistor Current Sources (link below), I made an error in my measurements because I ignored the loading effects of one of the meters. Since every mistake is really an opportunity to learn - hopefully you'll learn from my mistake! Even though there were two subtle clues that this error was there, I ignored them - shame on me!

Martindale CMi210 Insulation Clamp Meter Review

A look at the Martindale CMi210 Insulation Clamp Meter:
http://www.tester.co.uk/martindale-cmi210-insulation-clamp-meter

Uniquely designed for measurements of current and insulation, the CMi210 is a multifunctional clamp meter ideal for use in both domestic and industrial electrical installations.

The unique insulation testing function allows this meter to do what other clamps can't: test insulation levels up to 6GΩ with five different selectable test voltages from 50V to 1000V. It also has built-in, large-size 57mm jaws, making it suitable for clamping directly around larger conductors in order to test AC current to 1500A and DC current to 2000A.

A built-in multimeter is also included and the CMI210 can measure DC voltage to 1000V, AC voltage to 750V, resistance to 60MΩ, capacitance to 6mF, frequency to 10MHz, duty cycle from 5 to 95%, temperature (using a type K thermocouple) and continuity/diode.

Measuring the Speed of Sound with an Oscilloscope...and Hearing Test

Just a bit of fun...I try use an oscilloscope to measure / calculate the speed of sound. I also conduct a hearing test during the video.
