Re: Cheap pulse counter
That is interesting.
I have bought a lot of stuff from AliExpress, but now Sweden have imposed a fine on all packages from China, in an effort to force people to buy local.
I shall google this product, perhaps I can find it on E-Bay, delivered from another country.

Cheap pulse counter
Hi all,
I found a small pulse counter here There are the similar ones from more sellers, but this seems to be the cheapest (cca 0,5 EUR incl. postage to Czechia when ordered 5 pcs). I expect the buttons can be extended with wires and driven by an external contact, transistor or optocoupler. I have not tested the maximum frequency yet.
The counter can be used e.g. to count turns on a winding machine or passes through a door. With a prescaler and gating circuitry it might make a small frequency counter or receiver dial.
