Rob, I am only really designing and testing the board to control these displays.
Personally I only have 4 displays so my clock will be HH:MM but the person I am doing it for has a full set of 6. If you can find the displays then I can provide the controller. - Richard On Friday 1 November 2024 at 09:48:45 UTC Robert wrote: > Hi Richard > > Will that be a one off clock? > > > Rob > > On 1 Nov 2024, at 06:20, Richard Scales <[email protected]> wrote: > > I'm just working on a clock using these displays (or ones which look the > same but made by / badged Burroughs). > > > If you take one apart - do you end up with a bunch of bulbs pushed in to a > plate? > The ones I have certainly do. > I've just pulled the bulbs and plugged in LEDs (it was that simple), job > done. > By changing the incandescent bulbs to LED I trade authenticity for > functionality, robustness and longevity! > Now I have a board with a Wemos Micro , shift registers and buffers which > will control 6 of them.
