If you’re passionate about signal processing and retro tech, you’ll want to check out the Createc SC 01, a quirky handheld oscilloscope that recently caught the eye of [Thomas Scherrer] from OZ2CPU Teardown. This device, cheekily dubbed a “signal computer,” promises to be both intriguing and, perhaps, frustrating. You can view [Thomas]’ original teardown video […]
[Chris Borge] has spent the last few years creating some interesting 3D printed tools and recently has updated their 3D printable lathe design to make a few improvements. The idea was to 3D print the outer casing of the lathe in two parts, adding structural parts where needed to bolt on motors and tool holders, […]
This week Jonathan Bennett and David Ruggles chat with James Smith about Manyfold, the self-hosted 3D print digital asset manager that’s on the Fediverse! Does it do live renders? Does it slice? Listen to find out! https://floppy.org.uk/ https://manyfold.app https://github.com/manyfold3d/manyfold Did you know you can watch the live recording of the show Right on our YouTube […]
If you want to deliver the maximum power to a load — say from a transmitter to an antenna — then both the source and the load need to have the same impedance. In much of the radio communication world, that impedance happens to be 50Ω. But in the real world, your antenna may not […]
These days, not only are oscilloscopes very common, but even a cheap instrument today would have been the envy of the world’s greatest labs not that long ago. But back in the day, the home experimenter basically had two choices: buy a surplus scope that a big company was getting rid of or build a […]
The Domain Name System (DNS) is a major functional component of the modern Internet. We rely on it for just about everything! It’s responsible for translating human-friendly domain names into numerical IP addresses that get traffic where it needs to go. At the heart of the system are the top-level domains (TLDs)—these sit atop the whole […]
[Sebastian Lederer] has created Tridora: an unusual stack-based CPU core intended for FPGA deployment, co-developed with its own Pascal compiler. The 32-bit word machine is unusual in that it has not one but three stacks, 16-bit instruction words, and a limited ISA, more like those of the 8-bit world. No multiply or divide instructions will […]
It’s likely that many Hackaday readers will have had their interest in electronics as a child honed by exposure to an electronics kit. The type of toy that featured a console covered in electronic components with spring terminals, and on which a variety of projects could be built by wiring up circuits. [Matthew North Music] […]
[DTSS_Smudge] correctly intuits that if you are interested in an old Heathkit signal generator, you probably already know how to solder. So, in a recent video, he focused on the components he decided to update for safety and other reasons. Meanwhile, we get treated to a nice teardown of this iconic piece of test gear. […]
Despite the rise of ARM processors in more and more computers from embedded systems to daily driver PCs, the x86 architecture maintains a stronghold in the computing space that won’t be going away anytime soon. One of the main drivers of this is its beachhead in industrial systems; the x86 architecture is backwards-compatible farther back […]
