Build a neat little “flashy” circuit to get peoples attention. This worked very well! Schematic included with description.
How to build a programmable frequency counter for your favorite receiver, with “off the shelf parts!” Give that old radio receiver a digital NIXIE tube display. No special programming required. Join Paul in the Lab as he thoroughly explains how this, and many other frequency counters work.
In this video, Paul explains how to make a simple crystal oscillator, buffer and frequency division chain. This can be used for many different applications, IE: frequency standards, clocks, frequency counters and more. This is the second video in a series on how to build a Nixie tube frequency counter. Continue reading The Crystal Oscillator and Frequency Division
Join Paul in the lab as he explains how a Nixie tube works. This is the first video in this series on how to build a Nixie tube frequency counter from scratch.

Join Paul in the Lab as he repairs and improves a Precision Apparatus Company E-200-C series signal generator. Learn how to adapt a frequency counter to any older signal generator. Follow along as Paul describes how this signal generator works, and explains the factory schematic in detail. “More troubleshooting adventures.”
More electronic troubleshooting adventures! Join Paul in the Lab as he explains “in great detail” the circuitry inside a Heathkit T-3 signal tracer. Then Paul will discover and fix some design flaws. See how the Watt meter (eye tube) and noise tracer functions work.
Join Paul in the Lab as he designs a new battery for a small portable Tektronix 224 oscilloscope.

Removing surface mount electrolytic capacitors without desoldering them. This method is clean, and easier on the circuit board (in many cases) than using a heated desoldering tool for the same task. See how it’s done.
Detailed SONY CRF-320 repair and restoration video. This receiver is very much the same as the SONY CRF-330K, but without the tape machine. Follow along through the entire troubleshooting procedure, and learn how I discover and repair all the problems. See how the receiver performs after the alignment.
