Clock Update – test assembly of the LEDs
I’ve made a bit more progress on the clock I’m building. I built a dry run assembly of the LEDs I’m going to use instead of the filament bulbs the display would have taken originally. I did consider using fillament bulbs, until I worked out that replacing the duff filament bulbs was prohibitively expensive (it would have been by far the most expensive bit of the project) but this LED approach is non-invasive, so I can “do it properly” at a later date.
First step was to build a jig to hold the LEDs in position for soldering…
Once assembled, I insulated the cathode legs (which will be connected to a common negative battery via a resistor) with hellerman sleeves, and soldered them to a common wire. Then I sleeved the annodes and bend the legs to retain the sleeves ready for wiring.
Gently prising the assembly out of the jig, I fitted it to the display board and gave it a test run.
I think this is going to work out quite nicely! I’ve got another 3 of these assemblies to construct and fit, then I’ve got to wire the whole lot out to a tag strip and I can hook it up to the uniselector banks.
Oh, and build a case and sort out all the other stuff obviously.
