After nearly 2 years, the B7971 x 4 PC Board is back. This new version includes an RGB LED underneath each tube. Project documentation is here. Design docs are here. You can purchase them in the store
Update on the Cogwheel Nixie Shield..
First batch of shield boards have arrived back from Seeed Studio. It was my first order with them. I selected free shipping and it took exactly 30 days to arrive.
There are a couple of new features –
- Non-volatile clock with battery back-up, so you can make your a proper clock which keeps time when power is off
- Pads for optional larger inductor which will allow larger tubes to be driven.
I’ll be stuffing one up for test and handing it over to my assembler. Once I have a batch ready to sell, I’ll send out a notice. Watch this space.
Will probably switch to black boards after this initial run.
