Nixie Tube Clock controller

Six digit Nixie Clock Controller Chip Based on the microchip midrange microprocessor this package will allow you to construct your own six digit nixie clock with a minimal number of components. Features : 12/24 Hour mode Selectable lead zero suppression Selectable digit cross-fade Date display with selectable date format and display frequency Scrolling date with adjustable speed Digit cycling with various modes to prevent cathode poisoning Dimmer control and 24hr timed dim/display off function Software time correction for accurate timekeeping Alarm with adjustable snooze and tone Three button operation simple to useFlashing neons support at 1Hz See the following for brief outline of schematic : http://i483.photobucket.com/albums/rr197/nixieclock2008/Nixieclock.jpg You will receive a detailed printed schematic and parts list with your package, plus 18 pin IC holder. Clock is multiplexed at 680 Hz for flicker free display. Chip runs from 4MHz crystal and will be very accurate to one or two seconds per year (unlike AC operated versions). You will require 1x 74141 BCD decoder driver, and 6x MPSA42 + 6x MPSA92 high voltage transistors, plus a 4.000 MHz crystal. (See other listing) Please contact me with any questions.
