Large display counter

[Musiclogic]

Just wondering if anyone knew of a larger digit counter to be used on a winder. The cub displays are too small for my eyes unless I am right there, and I am trying to make a winder that I can let run while I do other things, thus a larger display will allow me to see the count from 10 or 15 feet away. 1/2" or larger digits, upto 1" max. Preferably LED or back lit LCD.
Any help would be greatly appreciated.

Hi,

An IVO NE214 and a Hengstler Signo 723 are two that I have (in fact I have two IVO ones) - they have 14mm LED displays.

There must be many others.

You can pick these up for about $10.00 US on E-Bay with last minuet bids.

At that price I got two of them but they cost me $13.00 AU.

There's no frequency specs but on trial they seem to be accurate up to 500 rpm.

A simple de bounce circuit may improve performance if you want to wind faster.

Are four digits enough? Always?

[Musiclogic]

4 digit should be enough for my plan, I was looking at readouts like such, just wasn't sure if anyone was using larger digit size counters. Cub's seem to be the most popular here. Thanks to all for the replies.

No, you are correct Joe, 4 digits aren't always enough, 5 is better but the counter will simply reach 0 and start counting again so on that rare occasion if you wanted 1200 winds you would stop at 200 the second time round.

Why would this not reach 1200, which is less than 9999? Or is this really a 3.5-digit counter, where the leftmost digit is zero or one? Actually, 1200 would work, as the range would be 0000-1999.

Ooooooooooooops , My bad Lol not enough zero's sorry 12,000 you would stop at 2,000 the second time round.

as long as it makes it to 9999, it should do, I'm just trying to get a better visual for distance, now on to finding a good optical sensor for dummies...LOL

Just a photo interrupter switch is all you need, similar to this one.

Wiring is simple, one side is powered typically with 1.5 volts DC but they do vary and the other side is connected to the counter.

They cost about $5.00 or you can scrounge dozens of them from discarded printer's like I did .

You can also scrounge other things like steel shafts and bushes, stepper motors and DC motors, the better printers like Epsom, Canon and HP have really good motors in them and oh yeh they also have power supplies, almost every thing you need to make a coil winder.

kind regards and merry Christmas to all,

That's fantastic info Walt, thank you very much, I am going to look into it. I am just now starting to learn about non-manual winders, and about more intricasies of winding and pick-up construction beyond the use of common ready to buy parts and wire, so I guess I am crawling slowly.
