[Ruvin Kub] likes magnets, a lot. Most of his projects feature some sort of magnet and his PC board agitation bath is no exception. You can see a video about the device, below. We’ll admit our Russian is pretty rusty, …read more
With how cheap and how fast custom PCBs have gotten, it almost doesn’t make sense to roll your own anymore, especially when you factor in the messy etching steps and the less than stellar results. That’s not the only way to create a PCB, of course, and if you happen …read more
When it comes to machining, the material that springs to mind is likely to be aluminum, steel, or plastic. We don’t necessarily think of glass as a material suitable for machining, at least not in the chuck-it-up-in-the-lathe sense. But glass is a material that needs to be shaped, too, and …read more

Like pretty much every other big conference, the Chaos Communication Conference is going virtual this year. What was supposed to be 37C3 has been rebranded as rC3, the remote Chaos Experience. It’s understandable, as a 17,000 person live event would have not only been illegal but a bit irresponsible in …read more
Tuning a desktop router and your board designs for isolation routing can be a bit tricky, with thin traces usually being the first victim. For simple prototype boards you usually don’t need tightly packed traces, you just want to isolate the nets. To do this with a minimum amount of …read more

Building a PCB at home can be frought. If you’re etching, there are chemicals and the nuances of toner transfer. If you’re milling, getting the surface height just right, and not breaking those pointy little v-cutters is always a challenge. [Robin] has tips for both of these cases, and solves …read more
In a time when cameras have been reduced to microchips, it’s ironic that the old view camera, with its bellows and black cloth draped over the viewscreen for focusing, endures as an icon for photography. Such technology appears dated and with no application in the modern world, but as [Ben …read more

The chances are you’ve seen the myriad cheap copyright-infringing edge-lit acrylic displays from Chinese suppliers everywhere on the internet, and indeed, etching acrylic with a modest CNC laser cutter has become easily viable to a lot of us in more recent years. However, if you want to kick things up …read more

One of the step changes in electronic construction at our level over the last ten or fifteen years has been the availability of cheap high-quality printed circuit boards. What used to cost hundreds of dollars is now essentially an impulse buy, allowing the most intricate of devices to be easily …read more

Join us on Wednesday, August 14th at noon Pacific for the Homemade Integrated Circuits Hack Chat with Sam Zeloof!
While most of us are content to buy the chips we need to build our projects, there’s a small group of hackers more interested in making the chips themselves. What it
