Hello together,
sorry, i cannot speak french, so i will write in english.
I want to give a short introduction to a completly NEW designed clock-board for the Twilight Zone clock, i designed with a friend of mine.
Meanwhile the board is revision 1.6 and runs perfect.
This board solves all of the problems of the original board and all other replacement clock boards.
Other replacement boards only use LEDs instead of the normal bulbs, but all the other design flaws are not corrected, so that it is only a question of time, when these boards, especially the OPTOS will fail.
What are the advantages of the new board? The original boards and all existing replacement clock boards drive the switch matrix directly from the optos
1.)
Completely NEW design of the board.
2.)
The original bulbs (the main reason for the heat in the clock) are replaced with cool burning Superlfluxx-LEDs. Warm-white Superfluxx-LEDs with a wide angle of 140 degrees are used, so that we have exactly the same brightness as the original bulbs. Very low power consumption, no heat-problems any more.
3.)
Now longer the weak OPTO-problem. This board will solve the weak OPTO-problem forever.
On the original boards and other replacement clock boards the OPTOS are directly integrated into the switch matrix, and this is the greatest reason for the unreliability of the original board. This design flaw by Williams is corrected with this board for all times.
4.)
You can use every "normal" OPTO, there is no longer any need to search for the obsolete original OPTO QVE11233.0086.
5.)
Fully rectified with a bridge rectifier GI-voltage for absolute flicker-free lightning of the Superfluxx-LEDs.
6.)
8 control-LEDs for the OPTOS, so you can see at once, if an OPTO makes a problem or a problem is on the CPU-board.
7.)
Power-ON LED.
8.)
You can deactivate the controll LEDs and the Power-ON LED by jumpers.
9.)
No weak Molex connectors as on other replacement-boards.
10.)
Single board design. This eliminates the board-to-board contact problems and gives a much better heat circulation in the clock board.
11.)
Mostly used discret components for easy repair.
12.)
Plug & Play replacement-board without any modifications. Just remove the old clock-board and put in the new board.
Here is a picture of the board.
Here you can see the board in "action" on test-bench:

And here with BLUE Fluxxies (looks very fine) and RED Fluxxies (i do not like that):

If you have any questions, send me a MP.

mais tous les autres défauts ne sont pas corrigés, et ce n'est qu'une question de temps pour que les optos lachent.
