We live in a world where most of us take the transistor for granted. Within arm’s length of most people reading this, there are likely over ten billion of them …read more Continue reading GLASNOST is a Computer That Makes Transparency A Priority
[Helge Fyske (LA6NCA)] may not be an actual spy — then again, he may be; if he’s good at it, we wouldn’t know — but he has built a couple …read more Continue reading Spy Radio Setup Gets a Tiny Power Supply for Field Operations
[Outer World Apps] noted that there was no PDP-8/V made by DEC — a variant that used vacuum tubes. So he’s decided to make one using about 320 6J6A tubes. …read more Continue reading The PDP8 That Never Was: Hollow State Logic
Here at Hackaday, we love following along with projects as they progress. That’s especially true when a project makes a considerable leap in terms of functionality from one version to …read more Continue reading Spy Transceiver Makes Two Tubes Do the Work of Five
One of the more popular trends in the ham radio community right now is operating away from the shack. Parks on the Air (POTA) is an excellent way to take …read more Continue reading The Peak of Vacuum Tube Radio Design
In our surface-mount age, it’s easy to be jaded about miniaturization. We pretty much expect every circuit to be dimensionally optimized, something that’s easy to do when SMDs that rival …read more Continue reading Tiny Three-Tube Receiver Completes Spy Radio Suite
Much like vinyl records, tube amplifiers are still prized for their perceived sound qualities, even though both technologies have been largely replaced otherwise. The major drawback to designing around vacuum …read more Continue reading Tube Amplifier Uses Low Voltage, Sips Battery
For most of us, vacuum tubes haven’t appeared in any of our schematics or BOMs in — well, ever. Once mass-manufacturing made reliable transistors cheap enough for hobbyists, vacuum tubes …read more Continue reading Reshoring Vacuum Tube Manufacturing, One Tube at a Time
It’s been a long time since vacuum tubes were cutting-edge technology, but that doesn’t mean they don’t show up around here once in a while. And when they do, we …read more Continue reading Two-Tube Spy Transmitter Fits in the Palm of Your Hand
