SP-353

My Nixie Addiction

Coming soon

A WeMos based creation to drive SP-353 Panaplex displays consisting of three boards that will sandwhich together to make a compact device which is not much larger to look at than the displays themselves.
Following on from this will be a version that supports three SP-353’s for a nine digit device. There may also be versions for the SP-352 Panaplex if there is sufficient demand. 

The design follows on from the SP-101 Panaplex clock and features the same core components: A WeMos Micro Controller, LV and HV Supplies, sensors and detectors, HV5622 shift registers and the SP-353 displays.
Ultimately this will form the basis of a platform that could be used with customised software to connect to the internet, sync NTP time, gather and display any required information that will fit on to 6, 8  or 9 7 segment displays.

So far this has been quite a learning curve though things are starting to come together. The various board designs are complete though I am still waiting for updated boards to arrive so they can be tested.

A BOM and construction guide is being prepared, a preliminary version is available on request.

The boards are very similar to the pictures on this page though with a few improvements and a few less blunders.

One ‘improvement’ has been to add a second row of connections between the controller and display board for reliabilty and rigidity. During testing, wth just a single row of pins, the boards required bolting together in order to retain a reliable connection. With the two rowns of pins, it was more robust and could be utilised without the need for additional fixings.

I am planning to offer boards with contsctruction notes and a B.O.M which includes ordering info for most of the parts from mouser.com.

If you  would prefer to purcase a set of parts which includes most of what you need (minus the displays and fixing hardware) then PM me for details.
