Toot

Working on a new clock design with FreeCAD and I like the look. The tubes are much better in person than in the photo but I’m a little disappointed with the brightness (I’m running them at 220V, 2.8mA which is what the data sheet recommends). I have a case of tubes so at some point I’ll go through and find a matched set.
