If you have been looking to learn about how to ‘scope your circuit from a wizard who resuscitates telegraphs and teletypes, then look no further that Trammell Hudson’s Oscilloscope class at NYC Resistor! (We know it’s happening, because we just shipped out the classroom supplies!)
One of the most powerful tools in debugging circuits is the oscilloscope — it allows you to visualize your analog and digital signals at millisecond or microsecond time scales. This 18 August class at NYC Resistor will teach you basic operation of a handheld oscilloscope: topics include how to setup different time and voltage scales, how to configure the trigger modes to capture fleeting signals and how to use the cursors to measure various qualities of the signals. We’ll also show how to use the ‘scope to trace a signal through a circuit to identify some common problems.
The other most valuable tool in your electrical test equipment toolbox is a multimeter for measuring the instantaneous values of three important electrical measurements: voltage, amperage and resistance. This class covers all three of these as well as the very important “beep mode” to check for electrical connectivity.
Get your tickets here! The class fee includes both a compact multimeter and a DSO Nano v3, an Open Hardware design that is a great getting started oscilloscope. With these in your toolbox you’ll be able to diagnose all manners of circuit issues.

Digital Multimeter – VIC830: This is a basic multimeter, I’ve played with it a bunch and I think its a great addition to a toolbox. It’s low cost and simple to use with a big clear display and all the measurements you need:
- AC/DC Voltage measurement
- Current measurement, from 1uA up to 10A
- Beeping continuity test, and diode test
DSO Nano v3 – Pocket-size color digital oscilloscope – v3.0: This cute pocket oscilloscope is a perfect companion to your tool box. For beginners, its a good starter scope – it is not as complicated as a benchtop scope so its easy to use. For advanced EE’s, its useful as a scope-on-the-go, for field-debugging, when you don’t want to drag your scope over, or when a floating-ground is needed (it will naturally do ‘differential’ measurements as long as its not plugged into a computer USB port). It’s not a terribly fast scope, best used for signals up to 100KHz, and it is only a single channel, but we still find uses for it all the time, especially with analog projects! The new version 3.0 has a nice fully-metal case for increased durability…. (read more)
