We often think of analog computing as a relic of the past, room-sized monstrosities filled with vacuum tubes doing their best to calculate Monte Carlo simulations or orbital velocities. Analog isn’t as dead as it might seem though, and analog mix signal design engineer [Nanik Adnani] gave us a crash course on analog circuits at […]
While most of us won’t ever play Wimbledon, we can play Pong. But it isn’t the same without the thrill of the sportscaster’s commentary during the game. Thanks to [Parth Parikh] and an LLM, you can now watch Pong matches with commentary during the game. You can see the very cool result in the video […]
If you take two objects with fairly smooth surfaces, and put these together, you would not expect them to stick together. At least not without a liberal amount of adhesive, water or some other substance to facilitate a temporary or more permanent bond. This assumption gets tossed out of the window when it comes to […]
With the ability to independently adjust the thrust of each of their four motors, quadcopters are exceptionally agile compared to more traditional aircraft. But in an effort to create an even more maneuverable drone platform, a group of South Korean researchers have studied adding flying squirrel tech to quadcopters. Combined with machine learning, this is […]
Lots of microcontrollers will accept Python these days, with CircuitPython and MicroPython becoming ever more popular in recent years. However, there’s now a new player in town. Enter PyXL, a project to run Python directly in hardware for maximum speed. What’s the deal with PyXL? “It’s actual Python executed in silicon,” notes the project site. […]
Let’s say your CAD workflow is starving for spatial awareness. Your fingers yearn to push, twist, and orbit – not just click. Enter the Nebula Mouse. A 6-DOF DIY marvel, blending 3D printing, magnets, and microcontroller wizardry into a handheld input device that emulates the revered 3DConnexion SpaceMouse – at a hacker price. It’s wireless, […]
3D printing is all well and good for prototyping, and it can even produce useful parts. If you want real strenght in plastics, though, or to produce a LOT of parts, you probably want to step up to injection molding. As it turns out, 3D printing can help in that regard, with injection molding company […]
If you’re like us and you’ve been wondering where those viral videos of single water drop chemical reactions are coming from, we may have an answer. [yu3375349136], a scientist from Guangdong, has been producing some high quality microchemistry videos that are worth a watch. While some polyglots out there won’t be phased, we appreciate the […]
Sometimes, a hack solves a big problem. Sometimes, it’s just to deal with something that kind of bugs you. This hack from [Dillan Stock] is in the latter category, replacing an ugly, redundant downspout with an elegant 3D printed pipe. As [Dillan] so introspectively notes, this was not something that absolutely required a 3D print, […]
You can still get moving-needle meters off the shelf if you desire that old school look in one of you projects. However, if you want a more flexible and modern solution, you could use round displays to simulate the same thing, as [mircemk] demonstrates. At the heart of the build is an ESP32 microcontroller, chosen […]
