There aren’t many people who could do an hour-long video reviewing an oscilloscope, but [Kerry Wong] is definitely one of them. This time, he’s looking at a UNI-T MSO2304X 300 MHz scope. The review might be a little long, but the scope — like many modern scopes — has a lot of features for measuring […]
One of the blockbuster talks at last year’s Chaos Communications Congress covered how a group of hackers discovered code that allegedly bricked public trains in Poland when they went into service at a competitor’s workshop. This year, the same group is back with tales of success, lawsuits, and appearances in the Polish Parliament. You’re not […]
Let’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit signals through light beams. Forget expensive lasers or commercial-grade equipment; this video by [W1VLF] offers a simple and cheap entry point for […]
If you just want to use a debugger for your microcontroller project, you buy some hardware device, download the relevant driver software, and fire up GDB. But if you want to make a hardware debugger yourself, you need to understand the various target chips’ debugging protocols, and then you’re deep in the weeds. But never […]
If you’re into building large projects, you’ll eventually find yourself looking at wire rope. Multistrand steel wire used as antenna guy wires, bridge supports, and plenty of other uses. The [HowNot2] team tested an old rule of thumb for wire rope. “Never saddle a dead horse”. Click through the break for more: The old saying […]
The early 1990s were an interesting time in the PC world, mainly because PCs were entering the zeitgeist for the first time. This was fueled in part by companies like Intel and AMD going head-to-head in the marketplace with massive ad campaigns to build brand recognition; remember “Intel Inside”? In 1993, Intel was making some […]
[Maker’s Fun Duck] has a recent video review of a cheap thermal camera from a company called Kaiweets, which you can see below. It checked all of his boxes: It was standalone, handheld, cheap, and not too cheap. The question is: does it work well for the kinds of things we would do with such […]
This account of running DOOM on a PCB business card isn’t really about serving the “Will it DOOM?” meme of getting the classic game to run on improbable hardware. Rather, this project has more to do with getting it done right and leveraging work that’s already been done. We’ll explain. You may recall [rsheldiii]’s previous […]
If you remember the 80s arcade game Dragon’s Lair, you probably also remember it was strikingly unlike anything else at the time. It didn’t look or play like anything else. So it might come as a surprise that it was ported to Nintendo’s Game Boy Color, and that took some doing! Dragon’s Lair used LaserDisc […]
The PolyDye system installed on an Elegoo Neptune 2 printer. (Credit: Teaching Tech, YouTube) Being able to 3D print FDM objects in more than one color is a feature that is rapidly rising in popularity, assisted by various multi-filament systems that allow the printer to swap between differently colored filaments on the fly. Naturally, this […]
