It is hard to show in a photo but in daylight the digits are not distinct enough. I think I need to pump up the volume. I'm wondering if I should actually drive the filament harder... Currently measuring 3.2VAC across the filament. |

I upped the filament voltage and now at 4.7VAC... definitely think it's a bit wimpy though... looks like I need a 50V design (A google suggests not all IV-18s are identical https://hackaday.io/project/2360-iv-18-arduino-clock/log/18373-two-version-of-iv-18 ... some look quite transparent... some, like mine have a reasonably solid internal structure,... and some need more grid voltage than others...) |
