If you’re a fan of vintage electronics and DIY tinkering, you’ll find this teardown by [Thomas Scherrer] fascinating. In a recent video, he delves into a rare piece of equipment: …read more Continue reading Tearing Down a Digital Scope from ’78
As Wikipedia defines:
White-box testing is a method of software testing that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing).
When the code is a target of its own, this i… Continue reading Are peripheral issues and systems normally considered in a white box penetration testing scope?
Modern computers are so fast and complex that we would seldom try and fix them on a component level with simple DIY tools. Working on an early 1980s computer is …read more Continue reading Fixing a C64 With a Cheap $20 Oscilloscope
[Adrian] had a Commodore computer to fix and decided to see how his latest tiny portable scope would work. He paid $57 for the tiny little test instrument although the …read more Continue reading Cheap Scope Troubleshoots Commodore
One of the best things about the Internet — especially the video part — is that you can get exposed to lots of things you might otherwise not be able to see. Take oscilloscopes, for example. If you were lucky, you might have one or two really nice instruments at …read more
I’ve seen some sample “What would you like to be pentested?” page (I can’t find or remember the exact source) where Cyber, Physical and Social were asked separately (among other areas like Wifi, Network, WebApp, etc). Let’s a… Continue reading Is Social Engineering out of scope unless explicitly requested? [closed]
In the world of oscilloscopes, as in the rest of the test equipment world, there’s always some trickery afoot. Companies will often offer different models to the market at different price points, in an effort to gain the widest possible customer base while also making the most profit. Cheaper, less …read more

It’s that time of year again, and the Christmas hacks are flooding in thick and fast. To get into the Christmas spirit, the FoxGuard team wanted a custom ornament to hang from the tree. They may have gotten more than they bargained for.
It’s a simple build that demonstrates the basic techniques of working with DACs and scopes in a charming holiday fashion. A Tektronix T932A analog oscilloscope is pressed into service as a display, by operating in XY mode. A Teensy 3.5 was then chosen for its onboard digital to analog converters, and used to output signals to draw …read more

The oscilloscope is an essential tool of any electronics bench, and it is also an instrument whose capabilities have expanded exponentially over the decades. Your entirely analogue CRT ‘scope of a few decades ago has now been supplanted by a digital device that takes on many of the functions of both an expensive multimeter a frequency counter, and more. At the top end of the market the sky is the limit when it comes to budget, and the lower end stretches down to low-bandwidth devices based upon commodity microcontrollers for near-pocket-money prices.
These super-cheap ‘scopes are usually sold as kits, …read more

Here at Hackaday, we’re suckers for vintage instruments. More than one of our staffers has a bench adorned with devices spanning many decades, and there’s nothing more we like reading about that excursions into the more interesting or unusual examples. So when a Tweet comes our way talking about a very special oscilloscope, of course we have to take a look! The Tektronix 519 from 1962 has a 1GHz bandwidth, and [Timothy Koeth] has two of them in his collection. His description may be a year or two old, but this is the kind of device for which the up-to-the-minute …read more
