Hey - Cute! Glad you quoted the inspiration or I/we may have thought you watch too many zombie etc movies [or games]. Developments:- The pcb in the mouth could be shaped as [or inserted in] a bone(s) along the lines of skull-and-crossbones. Or, the pcb could be flexible and wrap-around the mouth/teeth.
good one Morris, John K Adelaide [Happy New Year to you too.] ----- Original Message ----- From: Morris Odell To: neonixie-l@googlegroups.com Sent: Sunday, January 05, 2014 11:05 AM Subject: [neonixie-l] My latest clock Hi all, I was in New Zealand recently and visited the Clapham National Clock Museum in a town called Whangarei. One of the items there caught my eye, it was a German skull clock from the 1920s as seen here. I thought a Nixie version would be just the thing for my office at the Institute where I am a senior physician. A couple of weeks of intensive work over the summer break and here it is: http://youtu.be/6rHZqU2x3EA The skull is a plastic anatomical model which has been surgically modified to fit two dekatrons in the orbits. There's also a small speaker in the cranial cavity to sound the ticks and the Westminster chimes. The devices in the nasal cavity are a LED and a PIR sensor to switch on the display only in the presence of warm live humans. The red button on the front of the box is the alarm switch. The time display is made using Russian IN-17 tubes multiplexed in 3 groups of two. In the box is a PCB with an AVR micro and appropriate power supply and interface electronics for the tubes and speaker. The dekatrons are purely ornamental and not part of the timebase as in previous clocks I have made. As this clock is going into an internal office there's no GPS receiver included so it is set manually and gets its timing from the mains frequency.
