This clock is based on Vacuum Fluorescent Display tubes. They are a seven-segment based display like most led clocks but these are quite a bit different. For starters, this clock costs nearly 100x as much as your normal department store clock. The digits have a beautiful cyan color and the design of the tube allows you to see the inner workings. Image and brief description are from Nocrotec
- Digit height: 0.6″ (15mm)
- 12/24h mode
- Date in configuration DD.MM.YY or MM.DD.YY
- Leading zero suppression: The leading zero can be blanked or shown
- Cross fading: different modes to fade the digits from one number to the next
- Alarm clock
- Power down mode: tubes and supply can be totally switched off for a user programmed period in order to save energy and increase life expectancy of the tubes
- 12VDC input voltage
- Time is battery buffered when no line power is available; battery will last for more than 10 years
- User settings are always stored
- Case made of massive cherry wood and shiny black anodized aluminum as used for high-end audio equipment.
I am a big fan of Nocrotec's work and while doing my daily eBay search, I discovered that Dieter released a new VFD clock based on the GE-100 tubes. I have no idea where he finds sources for some of the odd tubes but I have never encountered these in person let alone in a clock for sale. These are easily the most elegant VFD tubes I've seen. The individual elements are rounded giving the display a much softer look than normal seven segment devices. Other than that, it appears to have the same specs as his other devices. At $259, this is a solid buy. Be sure to check out the links below for more information.
User Turbo_Hobby has released a new clock based on the IV-18 VFD tube and it looks pretty slick. There has been other clocks based on this tube but no other ones, based on my recollection, include a calculator function. That's right, it is also a calculator. It seems fitting that the tube that was originally designed for calculators is finally being used for one in this vacuum tube Renaissance.
The production time on each one of these devices is significant. Each one of his creations is hand assembled and even the transformer is hand wound. In practice, this means that he is only able to produce about one per month. Given that, the starting price is pretty good. (I sure wouldn't want to hand solder the SMT components.)
Turbo_Hobby is also the same guy who created the single digit nixie clock that I really like. He doesn't have a lot of feedback on eBay yet but I would not hesitate to do business with him again.
From the auction:
This is a fully assembled IV-18 VFD clock, with alarm, date, temperature and calculator function! Largest 8-digit VFD tube from USSR, NOS. Please refer to the video below or contact me for detailed explanation. Assembled with high-quality SMD components, with calibrated accurate clock pulse generator. The clock can be powered by either mini USB port or a 3.5mm 5V DC power supply, and keeps time by a SMD lithium battery when powered off.
Price: 49.95 EUR
Kosbo has just come out with a new VFD clock that is different from just about any other on the market. Instead of using discreet 7-segment tubes like the IV-11, this used one single display in the shape of an analog clock.
I personally own one of his IV-11 clocks and I’m quite happy with it. The PCB board is professionally assembled and I like the design of it. This round VFD clock takes it to the next level – soon there will be an acrylic base to complete the device and based on the renderings provided, it looks quite attractive.
Once the base is released, I may order one and do a more formal review based on that. In the mean time, go over to Kosbo.com and check out the rest of the photos and the specs. If you already have one of these, please leave me a message in the comments. I'd really like to get your opinion on this device.
