Collaborate Disseminate
[Applied Science] wanted to make some metal parts with a lot of holes. A service provider charged high tooling costs, so he decided to create his own parts using photochemical …read more Continue reading Better Sheet Metal Parts with Chemistry
Brass plaques are eye-catching because no one makes them on a whim. They are more costly than wood or plastic, and processing them is proportionally difficult. [Becky Stern] picked the …read more Continue reading Brass Plaque Honors Brother
Sometimes it might seem as if your electronics are just jinxed. For [Niva_v_kopirce] it was the control board of his nephew’s RC car that kept frying the transistors. In situations …read more Continue reading RC Car Repair With Beer Can Solder Stencil
What does it take to make your own integrated circuits at home? It’s a question that relatively few intrepid hackers have tried to answer, and the answer is usually something …read more Continue reading Old Printer Becomes Direct Laser Lithography Machine
We’re not aware of any authoritative metrics on such things, but it’s safe to say that the Ender 3 is among the most hackable commercial 3D printers. There’s just something …read more Continue reading Simple Mods Turn 3D Printer into Electrochemical Metal Cutter
We were trading stories of our first self-made PCBs in the secret underground Hackaday bunker, and a couple of the boards looked really good for first efforts. Of course there …read more Continue reading Embrace the New, But Don’t Forget the Old
Atomic force microscopy, laser ablation, and etching with a witches brew of toxic chemicals: sounds like [Zachary Tong] has been playing in the lab again, and this time he found …read more Continue reading Getting a Fly’s-Eye View with Microfabricated Lens Arrays
It’s a problem that few of us will likely ever face: once you’ve built your first homemade integrated circuit, what do you do next? If you’re [Sam Zeloof], the answer …read more Continue reading Garage Semiconductor Fab Gets Reactive-Ion Etching Upgrade
Looks and RGB LEDs are usually not a priority in tool batteries, but [Oleg Pevtsov] decided the battery for his DIY vacuum cleaner needed to be different. In the process, …read more Continue reading A Vacuum Battery Made For Looks And Learning
We all remember the litany from various math classes we’ve taken, where frustration at a failure to understand a difficult concept bubbles over into the classic, “When am I ever …read more Continue reading JavaScript App Uses Advanced Math to Make PCBs Easier to Etch
