Fresh hacks every day
If Nixies aren’t cool enough, maybe it’s time to step it up to magic eye tubes.
Magic eye tubes are, like Nixies and Dekatrons, display tubes. Unlike the alphanumeric characters of Nixies or rotating points of light in a Dekatron, Magic eye tubes are either bar graph or ‘Pac-Man’ displays that were used to show the signal strength of … Read the rest
A few months ago, we rolled out an updated Hackaday, a badly needed new layout replacing the HTML and CSS that had remained unchanged since 2004. Of course a few people didn’t like change and complained about slow load times. We’ve experienced a slightly slower load time as well, so we’ll just wait until the year 2020 when our computers … Read the rest
After building his first tube amp from a kit, he set to work on his next amp build. Since tube amps are a much more experimental endeavor than their solid state brethren, [Jarek] decided to make his next amp unique with military surplus subminiature tubes, and in the process created the smallest tube amp we’ve ever seen.

As part of her personal collection she somehow acquired a Launch Vehicle Digital Computer board for a Saturn V rocket. This particular unit was never used. But it would have been had the Apollo program continued.

The TRS-80 Model 100 was an amazing piece of kit when it was released. Able to run for a week with just four AA batteries and smaller than some laptops today, this portable version of the TRS-80 saw action with war correspondents covering the Falklands invasion. A pedigree a MacBook Pro will never be able to live up to, it … Read the rest
Here’s an exercise in excess if we’ve ever seen one. While working on his undergrad at Michigan State, [Gregory] thought it would be a great idea to build an all-tube home theater system. He calls his seven-foot tall rack of amplifiers ‘Frankenstein,’ and we’ve got to agree this build is an impressive monstrosity of engineering prowess.
[Gregory]‘s Frankenstein is … Read the rest
This heavily populated PCB is a recreation of the original arcade version of Pong. That is an important distinction because the home version of Pong used a specialized chip to do much of the work. This is basically all stock logic, which explains the high component count. We wonder how many quarters it took just to pay for all … Read the rest
