Re: 2/4 - tube boards
- In thinking about this some more, I am going to do some experimenting
with shift registers to see if I can run 4 tubes independently.
The reason is that the Supertex HV5522 (and similar) have 32 outputs
A 4-tube board might consist of 2 HV5522's, a microcontroller and a
switched mode HV supply. The boards would then only require a 12V
supply and the data signal.
Need to test this out, but it could possibly made for less than it
costs to make 4 individual sockets. A 2-tube version sing a single
HV5522 could be a real possibility.
I will do some testing on this to see if I can get shift registers and
a micro to work together well enough to still provide independent
control of each digit.
