I found this great little RCA DR 2000 / DR 2010 tester on eBay.  For $4.99, it was worth every cent.  I cannot find much information on this device other than the markings on the markings on the device itself.  ”RCA Numitron Digital Display Device Demonstrator 1g1308″ The controls are pretty simple – the knob [...]

I need some help.  I have a PCB that I can’t identify and I am hoping someone can shed some information on this. It is a Packard Instrument PCB from 1971.  It has the numbers 7100398 and 5065082 on the board.  There are 7 RCA DR-2110 Numitron tubes soldered to the fron and each one [...]

Segmentus clock (concept) By Art Lebedev – $n/a http://www.artlebedev.com/everything/segmentus/ From the guy who brought us the Verbarius clock comes the Segmentus.  (Is anyone else noticing a naming pattern here?) This concept clock was built to address the challenge of creating a digital clock with hands.  While clocks have addressed this challenge before, this one brings [...]

Epoch Clock – By ThinkGeek (OEM unknown) I love this clock.  It is nerdy on so many levels but manages to keep a good formal arrangement.  Who says geeks can’t be designers? The Epoch in this case refers to the Unix Epoch (AKA POSIX Time) of 00:00:00 UTC Jan 1, 1970.  Basically, computers count time [...]

Here is a short utorual I wrote a while back to document cleaning the older white and clear keyboard.  This does not apply to the newer think keyboards Apple released in 2007. I love the design of Apple keyboards. The clean while surface supported by clear plastic looks great. However, after a few weeks of [...]

As they say in Monty Python: “And now for something completely different.” I love unique clocks.  Not grandfather clocks, not cheap $10 alarm clocks, I am talking about hand-made small quantity digital clocks.  Without any more filler text, here is my list of favorite clocks: Nocrotec Sylvia Clock By Dieter Wächter – $399 http://nocrotec.com/start.php?navi=5&pid=21&gtxtid=110&lg=en This [...]
