UV Printing PCBs
We always enjoy [Thomas Sanladerer’s] 3D printing videos. But his latest isn’t only about 3D printing. He shows how he uses a DLP printer — which has UV light, after …read more Continue reading UV Printing PCBs

Linux Fu: Don’t Share Well With Others
In kindergarten, you learn that you should share. But for computer security, sharing is often a bad thing. The Linux kernel introduced the concept of namespaces starting with version 2.6.24. …read more Continue reading Linux Fu: Don’t Share Well With Others
Turing Ring is Compact
One of the problems with a classic Turing machine is the tape must be infinitely long. [Mark’s] Turing Ring still doesn’t have an infinite tape, but it does make it …read more Continue reading Turing Ring is Compact
Voice Command Made Mostly Easy
Speech commands are all the rage on everything from digital assistants to cars. Adding it to your own projects is a lot of work, right? Maybe not. [Electronoobs] shows a …read more Continue reading Voice Command Made Mostly Easy
6502 Goes FPGA (Again)
While there has been no shortage of FPGA-based recreations of classic processors, we always enjoy seeing a new approach. Last month [Some Assembly Required] took on the challenge to recreate …read more Continue reading 6502 Goes FPGA (Again)
DIY High Flow 3D Printing
Sometimes we’re impressed by the sheer audacity of a project. [Stefan] rarely disappoints in that area, and his latest video shows him making an adapter to convert a normal 3D …read more Continue reading DIY High Flow 3D Printing
3D Printing Gets Tiny
Using a process akin to electroplating, researchers at the University of Oldenburg have 3D printed structures at the 25 nanometer scale. A human hair, of course, is thousands of time …read more Continue reading 3D Printing Gets Tiny
Hacking Film Processing with Coffee
Years ago, doing your own darkroom work was the only way to really control what your pictures looked like. In those days, coffee was what kept you going while you …read more Continue reading Hacking Film Processing with Coffee
Tiny 3D Printed Magnets Show Patterns
You normally associate a double helix with DNA, but an international team headquartered at Cambridge University used 3D printing to create magnetic double helixes that are about a 1,000 times …read more Continue reading Tiny 3D Printed Magnets Show Patterns
Lisp in 436 Bytes
You would assume that any programming language available back in the 1960s would be small enough to easily implement on today’s computers. That’s not always true though, since old languages …read more Continue reading Lisp in 436 Bytes
