Signal Processing Shenanigans: The Createc SC 01 Pocket Oscilloscope

If you’re passionate about signal processing and retro tech, you’ll want to check out the Createc SC 01, a quirky handheld oscilloscope that recently caught the eye of [Thomas Scherrer] …read more Continue reading Signal Processing Shenanigans: The Createc SC 01 Pocket Oscilloscope

Supercon 2023: Aleksa Bjelogrlic Dives Into Circuits That Measure Circuits

Oscilloscopes are one of our favorite tools for electronics development. They make the hidden dances of electrons visually obvious to us, and give us a clear understanding of what’s actually …read more Continue reading Supercon 2023: Aleksa Bjelogrlic Dives Into Circuits That Measure Circuits

How Realtime Is Your Kernel? Scope A GPIO To Find Out

Showing the scope screen and the BeagleBone setup side by side, with GPIO input and output traces shown on the scope screen.

When debugging something as involved as kernel scheduler timings, you would typically use one of the software-based debugging mechanisms available. However, in cases when software is close to bare metal, …read more Continue reading How Realtime Is Your Kernel? Scope A GPIO To Find Out

Wearable Scope Lets Your Fingers Do The Probing

For frantic hacking sessions where seconds count, this forearm mounted oscilloscope with fingertip probes built by [aniketdhole] might be just what you need. Well, maybe. It’s not immediately clear why …read more Continue reading Wearable Scope Lets Your Fingers Do The Probing

Gameduino + Mystorm = Oscilloscope!

There has to be more than one of us who over the years since the launch of systems like the original Game Boy have eyed up these handheld platforms and thought “You could make a really neat little oscilloscope with that!” But the commercial systems are closed-source, locked down, and proprietary, so in many cases there’s little easy prospect of such a device being created.

Fortunately though, there are now very accessible handheld gaming platforms, and [James Bowman], the creator of the Gameduino series of boards, writes in to tell us about an oscilloscope project for the Gameduino 3 created …read more

A DIY Nine Channel Digital Scope

Have you ever found yourself in the need of a nine channel scope, when all you had was an FPGA evaluation board? Do not despair, [Miguel Angel] has you covered. While trying to make sense of the inner workings of a RAM controller core, he realized that he needed to capture a lot of signals in parallel and whipped up this 9-channel digital oscilloscope.

The scope is remote-controlled via a JavaScript application, and over Ethernet. Graphical output is provided as a VGA signal at full HD, so it is easy to see what is going on. Downloading sampled data to …read more

Wireless Oscilloscope Review

[Martin Rowe] over at EDN recently put a $200 wireless oscilloscope to the test. The Areoscope 100A is a single channel scope in a probe body that communicates back to an Apple smartphone or tablet via Bluetooth LE. You can see the video from the post, below.

The original prototype of the device had a high bandwidth, but the production model only manages to have a 20 MHz bandwidth at 100 megasamples per second: nothing earth-shattering.

We aren’t above having a single channel scope to throw in a bag, but most of the ones we’ve looked at in the past …read more

FPGA Rescues Scope From The Dumpster

I’m always on the lookout for a quality addition to my lab that would respect my strict budget. Recently, I’ve found myself pushing the Hertz barrier with every other project I do and hence desperately wanted a high bandwidth scope. Unfortunately, only recently have 70 MHz to 100 MHz become really affordable, whilst a new quad channel oscilloscope in the 500 MHz to 1 GHz range still costs a fortune to acquire. My only option was to find an absolute miracle in the form of an old high bandwidth scope.

It seemed the Gods of Hand Me Down electronics were …read more
