In the spirit of this group, a large array of NE-2 bulbs would be a neat project. I've already used opto-triacs on my big clock; they should work nicely for a multiplexed display. If anyone is interested in sharing the effort to develop a 2-board solution (1 board roughly 8" x 10" for the bulbs, the other for the AC supply) then send me a private message. It would be roughly a 10x24 matrix of bulbs for each board, and I'm guessing a 4:1 multiplex rate would work. The AC supply would generate a roughly +/- 170V square-wave, around 250Hz, and would need to operate from 110-240VAC, 50/60Hz Control would be from readily-available FPGA boards on Ebay.
I've seen NE2's available from China for a decent price when purchased in-bulk. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
