I wanted a numitron clock on my desk. As, in my opinion, a decent looking enclosure is one of the hardest things to make I made the clock in the size of an altoids can so just a few holes should be made for an enclosure that looks not too ugly. It’s almost fully in SMD and can be powered using a USB port, making it a lovely clock for almost every desk.
In the end I ordered a custom enclosure from Schaeffer in Germany for a nicer looking clock.
The build process, design files and such can be found on hackaday.io as I used the project to try out hackaday io and see if it worked for me.The link is: https://hackaday.io/project/18166-numican
