Neon lamps are fun to play with. These old-school indicators were once heavily utilized in many types of equipment for indication purposes but now seem largely relegated to mains voltage …read more Continue reading Demonstrating The Photoelectric Effect Using Neon Lamps
[GloriousCow] has started working on a series of investigations into the various historical floppy disk copy protection schemes used in the early days of the IBM PC and is here …read more Continue reading Exploring PC Floppy Protection: Formaster Copy-Lock
Battery management is a tedious but necessary problem that becomes more of a hassle with lithium-ion technology. As we’re all very aware, such batteries need a bit of care to …read more Continue reading Hardware Reuse: The PMG001 Integrated Power Management Module
3D printing is all well and good for making low numbers of units, so long as they’re small enough to print in a reasonable time, but what if you want …read more Continue reading Fast 3D Printing With a Polar, Four Quadrant Custom Machine
The 3DConnexion Space mouse is an interesting device but heavily patent-protected, of course. This seems to just egg people on to reproduce it using other technologies than the optical pickup …read more Continue reading A simple 6DOF Hall Effect ‘Space’ Mouse
[Chuck Hellebuyck] wanted to clone some model car raceway track and realised that by scanning the profile section of the track with a flatbed scanner and post-processing in Tinkercad, a …read more Continue reading Using a 2D Scanner to Make 3D Things
[Hans Rosenberg] knows a thing or two about RF PCB design and has provided a three-part video demonstration of some solid rules of thumb. We will cover the first part …read more Continue reading A Simple Guide to RF PCB Design
We don’t know how you feel when designing hardware, but we get uncomfortable at the extremes. High voltage or current, low noise figures, or extreme frequencies make us nervous. [Orion …read more Continue reading An Open Source 6kW GaN Motor Controller
We’ve covered the Tiny Tapeout project a few times on these pages, and while getting your digital IC design out there onto actual silicon for a low cost is super …read more Continue reading Open Source High Speed SiGe IC Production For Free!
Displays are crucial to modern life; they are literally everywhere. But modern flat-panel LCDs and cheap 7-segment LED displays are, well, a bit boring. When we hackers want to display …read more Continue reading An Easy Transparent Edge Lit Display
