IEE Clock

April 27, 2010 by Caleb Kraft 21 Comments

The IEE clock looks somewhat un remarkable at first glance. Upon closer inspection though, you’ll find out that there are 12 light bulbs crammed in there for each digit. The bulbs sit behind a curved lens with the numerals on it. When the appropriate one is lit, it projects the number on the front of the clock. While it isn’t new, it is certainly new to us. It is also interesting that you set the time by rotating the little dial on the top right. While it may be easier to set the time that way, it seems that it would be prone to getting nudged on accident.

Victorian Styled Nixie Tester

April 16, 2010 by Caleb Kraft 9 Comments

While building some nixie clocks,[Blue_Metal] ended up destroying a few tubes. He found that having a tester sitting around would have been most helpful. Taking some pride in his tools, he put some major effort into building his nixie tube tester. It is quite visually pleasing, featuring hand cut brass framing, custom etched information panels. Scroll through his flickr set to see the build process in detail.

Tiny Tube Amp For Headphones

April 13, 2010 by Mike Szczys 14 Comments

We like to check in from time to time on the scratch-built tube amp scene. [Rogers Gomez] recently posted his build of a headphone tube amp. This is somewhat related to his work from 2008, but this time around it’s simple enough to serve as an entry into amplifier construction for beginners. The PCB layout is clean and simple, makes for easy board etching, and it’s small enough to fit into an enclosure that can pass as a headphone accessory. Only one tube is needed, with a total parts bill coming in around the $50 mark. If you build it, heed his advice on testing with a pair of cheap headphones before you risk plugging in your prized pair.

Still want an amp but don’t care to source the vacuum tube? [Giovanni], who sent in the original tip, build one a while back and housed it in an external CD-ROM enclosure.

Nixie Tachometer

A Nixie tachometer is new to us. We’ve seen tons of various displays, but not a tachometer. After having extensive annoyances with the factory ignition timing system in his totally awesome Holden Gemini, [Brett] installed a MegaJolt electronic ignition system. To top things off and add that extra bit of flair, he built a nixie tachometer to sit on his dash. Not only does it have the numeric read out, you can see a nixie “bar graph” on top as well. Skip to about 2:30 if you want to go right to the action. You can download the Arduino code from the forum post.

Tube Clock Database

[Brian] wrote in to show us a site he’s been working on for a while. He’s been building a tube clock database. We didn’t realize there was actually a big enough draw for such a site, but we have to admit that we spent more than a few minutes browsing through the different clocks. There isn’t a ton of data for each clock, but there are links to individual project pages wherever available. There is also a growing amount of information on the different components themselves, so submit any data you have that he’s missing to help flesh it out.

The video above wasn’t chosen for any reason other than it is quite stylish.

Vacuum Tube Tesla Coil

January 13, 2010 by Caleb Kraft 12 Comments

[xellers] may have been in 8th grade when he built this vacuum tube tesla coil, but he did a fantastic job. Unlike most of the tesla coils we have shown, this one doesn’t use a high current transformer from a neon sign. Instead, he’s gone the direction of vacuum tubes. He spent a total of about $125 which isn’t too bad. Most of us could reduce that cost by scrounging from our parts bin.

Need To Source Nixie Tubes?

December 18, 2009 by Mike Szczys 17 Comments

Nixie tubes make for fun projects but the fun can’t start until you get your hands on the hardware. Well, [Dieter’s] got you covered with his one-stop repository on Nixie tubes and where to get them. We know that Woz’s watch isn’t currently available because of a lack of tiny tubes an obsolete accelerometer. Ladyada’s Ice Tube Clock depends on a rare 8-digit VFD tube. But you can get around parts obsolescence by adapting these designs for an available replacement. So when you take on the Dekatron Timer or a Bottled Nixie Clock you’ll know where to turn for the goods.

Update: Our mistake about Woz’s watch. It wasn’t a tube shortage that put it out of production.
