Prolific woodworking YouTuber [Matthias Wandel] makes some awesome mechanical contraptions, and isn’t afraid of computers, but has never been a fan of CNC machines in the woodshop. He’s never had one either, so until now he couldn’t really talk. But he had the parts on hand, so he built a wooden CNC router. It’s lovely. […]
We were surprised when we read a post from C++ creator [Bjarne Stroustrup] that reminded us that C++ is 45 years old. His premise is that C++ is robust and flexible and by following some key precepts, you can avoid problems. We don’t disagree, but C++ is much like its progenitor, C, in that it […]
With so many cheap oscilloscopes out there, the market for old units isn’t what it used to be. But if you have a really old scope, like the Heathkit O-10 that [Ken] found in his basement, there is vintage cred to having one. [Ken’s] didn’t work, so a repair session ensued. You can see the […]
Like many pieces of lab equipment, oscilloscopes are both extremely useful and rather intimidating to a fledgling user. Unlike a digital multimeter with its point-and-measure functionality, digital storage oscilloscopes (DSOs) require fundamental knowledge before they can be used properly. Yet at the same time nobody likes reading manuals, so what is one to do? Try […]
It seems obvious once you think about it, but if you can spin your cell phone and coordinate the display with the motion, you can create a 3D display. [Action Lab] had used such a setup to make a display that you could view from any angle. After he showed it, a viewer wrote him […]
When you see a ventriloquist like [Jeff Dunham], you probably expect to see him with a puppet. This time – spoilers ahead – you won’t. Besides his fame on stage, [Dunham] is also a collector of vintage tech and a die-hard television enthusiast. In the video below, [Dunham] has gotten his hands on a rarity: […]
The MP3 file format was always encumbered with patents, but as of 2017, the last patent finally expired. Although the format became synonymous with the digital music revolution that started in the late 90s, as an audio compression format there is an argument to be made that it has long since been superseded by better […]
Generally speaking, writing your own games for retro consoles starts with C code. You’ll need to feed that through a console-specific tool-chain, and there’s certainly going to be some hoops to jump through, but if everything goes as expected, you should end up with a ROM file that can be run in an emulator or […]
In days gone by, a common retail hack used by some of the less honorable of our peers was the price tag switcheroo. You’d find some item that you wanted from a store but couldn’t afford, search around a bit for another item with a more reasonable price, and carefully swap the little paper price […]
