To do what ? How about an AC line sync timebase using a 'dekatron pendulum' ? The animated .GIF on this overview page: http://threeneurons.wordpress.com/dekatron-stuff/ is that of a pendulum, and here is the circuit: http://threeneurons.wordpress.com/dekatron-stuff/pendulums/ Its drawn using direct AC for power, too, but can easily be modified to run off of a switcher. If you use a switching PS, bring low voltage AC into your box. 9VAC to 12VAC. Use the switcher, for the nixie & dekatron voltages. Tap the (low V) AC like shown in the circuit, but make R7 (in the 1st circuit, R9 in the 2nd) 10K, instead of 1M. You can power the CMOS chips from +5V. The 'SWAP' signal will be 1Hz, locked to the household AC. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
