Hackaday Editors Mike Szczys and Elliot Williams dish their favorite hacks from the past week. Seems like everyone is trying to mill their own Mac Pro grille and we love seeing how they go about it. Elliot is gaga over a quintet of power latching circuits, Mike goes crazy for a dough sheeter project, and […]
AMD Epyc processors support Secure Encrypted Virtualization (SEV), a technique that prevents even a hypervisor reading memory belonging to a virtual machine. To pull this off, the encryption and decryption is handled on the fly by the Platform Security Processor (PSP), which is an ARM core that handles processor start-up and many security features of […]
The Raspberry Pi 4 has been in the hands of consumers for a few days now, and while everyone seems happy with their new boards there are some reports of certain USB-C power supplies not powering them. It has been speculated that the cause may lie in the use of pulldown resistors on the configuration […]
When the only tool you have is a hammer, all problems look like nails. And if your goal is to emulate the behavior of an FPGA but your only tools are FPGAs, then your nail-and-hammer issue starts getting a little bit interesting. That’s at least what a group of students at Cornell recently found when […]
In the past, you might very well have started programming in Basic. It wasn’t very powerful language and it was difficult to build big projects with, but it was simple to learn, easy to use, and the interpreter made it easy to try things out without a big investment of time. Today you are more […]
Rub two pieces of metal against each other hard enough, and it won’t be long before they heat up sufficiently to cause problems. That’s especially true when one is a workpiece and one is a tool edge, and the problems that arise from failing to manage the heat produced by friction can cost you dearly. […]
Some of the first Sony Discmans included rechargeable batteries. These batteries were nickel metal hydride batteries (because of the technology of the time) and are now well past their service life. The new hotness in battery technology is lithium — it offers greater power density, lighter weight, and a multitude of ready-to-go, off the shelf […]
