I've been searching for information for a vfd clock using individual tubes. I have a scad of IV-11 tubes and would love to build a clock.
I seems the problem is with the required power supplies, etc...most posts I find are three or four years old. I get the feeling interest is failing for vfd tube clocks because the price of these tubes is very low on ebay.
Does anyone have a schematic, etc...that I could beg borrow or steal??...better yet if it includes the necessary programmed PIC.
I'm 53 and studied two years EE in college before leaving for a career in telecom and I really don't want to learn PIC programming, compilation, burning the chips, etc...but I do love constructing and the building and assembly of the clocks.
Does anyone have any thoughts on how to take a MM5314 clock chip which has 7 segment output and drive/convert for vfd tubes?
I would also love to take one of my favorite nixie clock kits that uses a PIC processor and has BCD output and use it to drive the vfd tubes but have no idea how to do it.
I have a few basic clock kits that use the mm5314N clock chip and six individual 7 seg red led displays. The 7 seg led itself is 14mm tall. I have one or two of these and tried to convert to numitron tubes but the clocks are still not what I want them to be but they work...
Anyone interested in trading vfd info/schematic for 5314 clock chip led kit??
Regardless, I enjoy reading the posts and wish I had stayed with EE 30+ years ago instead of going into telecom...hind sight is perfect
Thanks for reading,
