In this article a simple and inexpensive LCD oscilloscope to be used as a display for the spectrum analyzer will be presented. Although a small LCD screen is unable replace a good analog oscilloscope, a LCD may be very useful in field measurements under strong daylight conditions, for battery operation or simply when the available oscilloscope is required for a different measurement at the same time.

Wilson writes:This oscilloscope uses a 1-inch diameter Mullard DH3-91 CRT. I found it at a car boot sale, priced เธ1. I’m ashamed to say I didn’t recognise what it was: I only bought it because it looked wierd and interesting! Ian did the main design and prototype work on the ’scope, then I rebuilt it with a PSU and front panel controls, and packaged it nicely. Click here to read about Ian’s prototype. The size of this oscilloscope is 164 x 83 x 83mm (6.5 x 3.25 x 3.25 inches).[more]

The Scopetris is an AtMega32 was equipped with R-2R ladder D/A converters for controlling the beam of an old oscilloscope. To get some fun out of the setup, a Tetris clone with chain reactions was implemented. Beat the highscore[more]

The .Net Oscilloscope is a Virtual Oscilloscope using PIC Microcontroller.The heart of the .NET Scope is the GP-3 PC I/O Board PIC Microcontroller circuit. This is a kit brought from AWC that allows you to read digital an analog signals and return the results through the serial port of your PC. You can also create PWM signals, tones, high/low signals, pulses, and counters with GP-3 circuit and control them with your PC.[more]

This circuit dates back to at least 1935 and is a simple cheap adapter that converts just about any oscilloscope into a component tester. It causes a component’s current vs. voltage characteristics to be displayed on an oscilloscope’s screen. The name “Octopus” is attributed to a Marine Corporal who reinvented it in 1968 while working working on Tactical Navigation Systems at NAS Newriver, NC. He called it “The Octopus”[more]
