It is one of Murphy’s laws, we think, that you can’t get great things when you need them. Back in the heyday of shortwave broadcasting, any of us would have given a week’s pay for even a low-end receiver today. Digital display? Memory? Digital filtering? These days, you have radios, and they aren’t terribly expensive, […]
Recently Radxa released the X4, which is an SBC containing not only an N100 x86_64 SoC but also an RP2040 MCU connected to a Raspberry Pi-style double pin header. The Intel N100 is one of a range of Alder Lake-N SoCs which are based on a highly optimized version of the Skylake core, first released […]
The last time we checked in with [Downtown Doug Brown], he had some cheap Altera USB Blaster clones that didn’t want to work under Linux. The trick at that time was to change the device’s 24 MHz clock to 12 MHz. This month, he’s found some different ones that don’t work, but now the clock […]
The BiVACOR THA hooked up with the CTO Dianiel Timms in the background. (Credit: BiVACOR) Outside of the brain, the heart is probably the organ that you miss the most when it ceases to function correctly. Unfortunately, as we cannot grow custom replacement hearts yet, we have to keep heart patients alive long enough for […]
Computer graphics have come a long way since the days of Dire Straits and their first computer animated music video in 1985. To move the state of the art forward has taken the labor of countless artists, developers and technicians. Working in just that field, a group from UCLA have developed an advanced system for […]
[Vadim Panov]’s 3D printed solar harvester is in effect a rechargeable outdoor battery, and the real challenge he faced when designing it was having it handle the outdoors reliably. The good news is that part is solved, and his newest design is now also flexible enough to handle a variety of common and economical components […]
There are a million and one ways to build your own CNC router, depending on your tastes, budget, and application, your design choices will differ accordingly. [Steve Tying] was well aware of this when undertaking his project, and built the machine that made sense for him. [Steve’s] build has a strong focus on keeping costs […]
“RISC architecture is going to change everything”, which is why [SHAOS] is building this cool RISC-V DIY retro-style computer. The project took inspiration from another hacker’s work in building a RISC-V emulator; shared in the Hackaday FPGA chat. He took it a bit further and got it going on an UPDuino v2.0 board which features […]
The last two years has been a particularly exciting time for KiCad, for users, casual contributors, and for the core developers too. Even so, there are many cool new features that are still in process. One bottleneck with open-source development of complex tools like KiCad is the limited amount of time that developers can devote […]
We’ve seen 3D image projection tried in a variety of different ways, but this is a new one to us. This volumetric display by Interact Lab of the University of Sussex creates a 3D image by projecting light onto a tiny foam ball, which zips around in the air fast enough to create a persistence […]
