Summary
| Description |
English: So the bulbs did not work well. I decided to try white LEDs. An anachronism, but they can be fitted with no modifications to the machine so I can go back to filament lamps if I ever get them.
Top row : I started with a white LED, a 1N4148 diode (to be connected in antiparallel to prevent excessive reverse voltage when the device is run from AC) and a 1k resistor. Middle row : These are connected together. They will then be covered with heatshrink sleeving and fitted to a contact base from one of the old bulbs. Bottom row : A complete indicator. I made 3 in total, of course. |
