Test Equipment Class

This weekend at NYC Resistor, I took the test equipment class taught by Trammel Hudson. It was a great class on how to use two very common tools for debugging issues with electronics.

The first half of the class covered how to use an oscilloscope. We used the DSO Nano v3 by Seeed Studios. This pocket-sized oscilloscope is powerful despite its small size. We first discussed how to measure signals and then moved on to more complex topics, such as using the triggering functions and figuring out baud rates based on the oscilloscope readings. The small size is a major plus, as it will fit nicely in my hack box. It’s a big step up from the giant analog oscilloscope that my grandfather used back in the day.

The second half of the class covered how to use a multimeter. This is a must-have for anyone who likes to tinker with microcontrollers as I do. We covered how to measure AC and DC voltage, resistance and amperage, as well as continuity testing. Even though I already knew how to use one, this was a great refresher.

Resistance is futile... or approximately 220 ohms.

Of course, no class is complete without sticking something into the electric socket!

The best part of the class was that we got to keep the tools! I can’t wait to break things so I can use my new tools to fix them!
