You may have been seeing a VGA-to-Scope projet, but this is a “spin-off” from the VGA-to-Scope converter, it take in composite video rather than VGA to display on an oscilloscope. Also, many of the circuits that makes the VGA-to-Scope converter very rugged and flexible for many oscilloscopes have been simplified or omitted. The buffers and inverters on the outputs of the ramp generators have been removed, although some sort of buffer would be recommended for the outputs.[more]

This project show you how to create Rotating Sprocket Wheel on the oscilloscope.The circuits that don’t really do anything useful, but are really neat nonetheless.Matt Bennett say “An interesting side-effect is that this circuit very clearly shows some of the shortcomings of digital oscilloscopes. Whenever an oscilloscope salesman comes around, he whips out this box with a switch and 2 BNC jacks. It has been known to render speechless the best salesmen from HP and Tektronix. They usually dismiss it as a toy, but I think that is just because they have to follow the party line: Analog scopes are dead. I have seen a digital scope or two accurately mimic the analog, most notably the Digital Phosphor scopes from Tektronix, but in general, the RSWG breaks digital scopes.”[more]

Here is the Oscilloscope Clock. V3.0.The firmware of the Dutchtronix AVR Oscilloscope Clock has been released. The clock has enhanced graphics and many new features like Date display and set, Roman Numerals Dial, 24 hr Dial, Binary Clock display, hexadecimal numeric time, fractional seconds display, Automatic Daylight Saving Time (US and EU) and GPS NMEA input: connect the clock to the serial port of GPS device and you’ll never have to set the time or day again.[more]

A high speed A/D converter (TLC5510) drives the USB module directly.Maximum clock rate is about 1MHz resulting in bandwidth limit of about 500KHz. The sampling rate may not be very exciting for RF people, but can be perfectly acceptable for audio and teaching work.[more]

Designed by Bojan Banko he write: was doing an ultrasound project when at one point I couldn’t move forward without an oscilloscope.I’m hobbyst in electronics, and I don’t really need a real oscilloscope. I don’t want to spend money on it and I don’t have enough space in my electronics corner for it.So, I took a look what is offering at the Net. I found a great (and free) solution: Winscope. It’s using the sound card and that’s all you need. The problem with this solution is that you just can’t get the sample rate more than 44kSamples/sec. That’s enough for audio signals(<15kHz), but not for 40kHz ultrasound signals. You need around 10 samples per cycle (or more) of the signal you are measuring to get any decent waveform to actually view.[more]
