That sounds awesome! Yes, I was thinking about that pin output as well. That would also mean you can use a standard ribbon cable + connectors. So you think that would fit on 2 tiny boards? Also, how many interconnect wires would be needed between the 2 boards?
I'm not really sure what the advantage of the 3x2 multiplexing would be vs 6-tubes multiplexing. Wouldn't you need less drivers and wires to the tubes when multiplexing them all?
As for the money part; it totally depends on what you want to do with the design when it's finished. If you see it as a personal assignment from me then I would pay for all the labour but it would mean you wouldn't be allowed to sell it to others We could also work something out like splitting costs for labour and start selling them both. Anyway, I've got no idea how much time something like this involves.
There is hole on the market for something like this. Do you think you will be able to suply kits by yoursels? Maybe you could team up with somebody who already sells clocks, so more people would buy it.
How big are you aiming?
I personaly would be really interested in buying kit or two. If you look on the market now, you can get really nice kits from pvelectronics.co.uk for as low as 70 USD (im talking about the QTC clock) Would price like that be possible?
I believe I can get all the functions including power supply on one board with dimensions less than 2x2.5x1.5, no need for two boards.
No problem with building - I'm thinking of putting this board into production anyway. I already build surface mount boards for clocks - see
I like 3x2 multiplexing, much brighter then 6x1. The board could have an option to allow 6x1 multiplexing if that makes sense.
Not sure on price, but < $75 should be doable. A little more expensive than SixNix, but also a lot smaller... (and 90% assembled, I would do the surface mount soldering). I would supply board with programmed processor and instructions.
Should the nixie anode resistors be on the board, or wired to the Nixie's?
