I've used this counter in some of my electronics, but I decided to release it on it's own because it's so small :D. This is (at least from what I have seen) one of the smallest dual direction counter's that does NOT use PSTN. Unfortunatly, it does use a lot of WIFI to make it work.
Good job :D If I find an use to this, can I use it? (not sure if I would use this though)
Sure :D.
Yeah, yours is really good because it has no wifi.
