HACKADAY prize ENTRY: hot LOGIC
A few weeks ago, [Yann] was dumpster diving as well as discovered something of interest. two vacuum tubes, an ECC83S as well as an EL84. This was certainly the droppings of a regional guitarist, however [Yann] wished to understand if he might develop something helpful out of them. An amplifier is far as well pedestrian, so he settled on a vacuum tube computer.
The typical pentodes as well as triodes you’ll discover in a tube amp need a great deal of support components like output transformers, tube sockets, as well as high voltage power supplies. This was a bit as well challenging for a tube computer, however after a bit bit of searching, [Yann] discovered a much better choice for his MINIVAC — subminiature vacuum tubes. These need fewer support components, as well as can be discovered for extremely sensible costs with the typical element suppliers. His entry for this year’s Hackaday prize is hot Logic. It’s a computer — or at least computer elements — developed out of these tubes.
The tubes in concern are a few 1Ж29Б-В and 6Н21Б tubes, a vacuum pentode as well as double triode, respectively. add in a few diodes, as well as that satisfies the demands for being adequate to develop a computer. As a neat bit bonus, these tubes have demands that are extremely simple to meet. The filament on the 1Ж29Б-В tube only needs 1.2 Volts.
These subminiature tubes are a bit underappreciated in the world of audiophililia as well as diy electronics. That’s a bit of a shame; these tubes are the most technologically advanced vacuum-based innovation ever created. They were the heart as well as the brains of ballistic missiles, as well as if you look difficult sufficient you source numerous them at extremely sensible prices. A vacuum tube computer needs a great deal of tubes, as well as if anybody will be able to develop a vacuum tube computer it’s going to be [Yann] as well as his stack of Soviet surplus.
