Hello,

My sons has been playing table tennis for about 2 years.
They use scoreboards that work on the basis of bullet LEDs.
Unfortunately, the person who maintained it passed away a few years ago.

Now they had said that some were broken and I thought, I can check this.
And yes it wasn't too easy but I did it.

Now they have given me a box full of parts to make new scoreboards.
These are presented completely differently.

There is a nucleo F446RE and self-made pcb boards and the necessary chips and wires and power supplies.
But have to be honest this is quite new to me.

The chips included are TLC6C598.

There are also pcb boards for the bullet leds and 7 digits.

Now my question was since I have not received any schematics if someone can help me to try to make something with these parts?

the club would also like to try to share the score via wifi or other way on a screen if this is possible?

With best regards,

Nicky

@qwaresniper I think the best way forward is to forget the box of parts and just write up a statement of requirements. As far as I can recall about table tennis, it's just the awarding of one point (I know of 2 different scoring rules) to the player who was last successful. The old rules were points only awarded if that player was serving. In either case, it's just pressing a button and advancing a counter with attached LED. Adding a couple lines of code to broadcast the actual score via wifi is also trivial.

Good luck.

Hi Ron,

What you say is quite logical but this is also a bit I'm not familiar with yet... .
Writing some code and linking buttons to LEDs is not yet a standard for me.

Also writing program or links for sending to a screen actually.

But did someone need some spare time to help me with that?

Best regards,

Nicky

These are examples of old scoreboards and parts.

Maybe someone can and wants to help me?

best regards,

Nicky

@qwaresniper 

Without data sheets and in particular circuit diagrams I don't think you realise how time consuming and complex the task would be. Trying to trouble shoot without having physical access to the hardware would be a nightmare. I doubt anyone has the time or interest for that.

So if you want to make use of the parts you need first to learn electronics and programming. The programming is involved with the Arduino compatible board I see is used. Extra programming and hardware would be required for wifi usage. You need all that knowledge anyway to maintain or modify the display boards in the future.

Although I suspect any hardware guy here could make use of the LED display boards and power supply given the specs what @zander suggests is probably how they would go about making a score board themselves using the parts.
