I don't have the knowledge to design my own circuit boards but I do solder a lot so for my designs and ideas I depend on kits being released by others.
I'm kind of surprised that no-one has ever come up with a tiny SMD board that can drive 6 tubes and 2 colons and can be used as a base for new designs. Anode resistors could be chosen depending on the tubes used.
What I'm seeing all the time is PCBs that match the size of the tube board. Why? I see a lot of people like to show off the electronics inside the clocks but I don't like that at all. I just would like a tiny PCB that can fit into small cases and lets me choose how to wire up the tubes.
I did order the remote tube clock from pvelectronics but it's so large that it needs to be used outside the actual clock and you have to run a thick 22 wire cable from the clock to the case.
The closest I've found so far is the micro nixie clock from kosbo.com
However, it's only 4 digits and some components are still on the tube board.
Taking a design like that, adding 2 digits and replacing certain parts with SMD could probably keep it that tiny I guess?
I'd love if someone capable of desiging such a board could comment and share ideas.
I also have another model, the
, that is the same electronics packaged into a smaller 2-board set.
The boards can be either "L", or stacked, making for a compact footprint. $175 without enclosure.
Both of these clocks are GPS based, and set the standard for features that other commercial sellers reference their designs by.
You'd only need to size the anode resistors to the tubes chosen.
Thanks for the reply.
Yes, I could do that but like I said, most kit's boards aren't made very small because they're made the same size as the the tube board which, most of the time, is pretty large. The board of the GPSII is also way too large for what I have in mind (think regular alarm clock size). The board of the micro nixie clock I'm talking about is only 35x60mm.
