Impossible to find!?

[ivconic]

Sheeesh!
Sometimes i am very unpleasant suprised with Google and few other search engines! Sometimes those are very stupid!

I am looking desperately for project/schematic, based on PIC microcontroller, device called telephone calls meter, or billing meter, or charge meter.

I need full, good project to build.

It must have own LCD display.It must counts pulses during talking. It must have reset to zero option, but also must have "memory" to calculate overall pulses spent, per day or total.
Even a bit simplier project will do.

So i spent 3 hours of searching net, without success!

There are few simple and stupid schematics with transducer type counters. Bull!
Also there is one with ordinary calculator...bull!
I need something more smarter.

Google,Lycos,Altavista,Search .....etc.etc.. all are very limited.

Anybody have simillar project? Or link to project?
Help!

A bit ugly... but maybe works...

well... it's just a toy... but could give some idea...

Ivice, telefonska centrala salje impulse 16kHz prema korisniku za svaki impuls koji se broji u centrali.
Jednostavno napravi sa NE567 filter i na njegovom izlazu dibijes digitalne impulse koje mozes brojiti sa bilo kojim brojacem. Moj Engleski je jako slab . . .

Ma super ti je Engleski...cim sam sve razumeo!
Znam...16kHz carrier. Ima nesto prosto na elektronika.ba
Problem je sto meni treba kompletan sistem sa memorijom,lcd prikazom, presekom stanja..... Prava mala masinica!
Ima toga garantovano, samo treba naci. Sve moguce kljucne reci sam isprobao na Google-u i uvek mi izbaci neke bezveze linkove.
Hvala u svakom slucaju! Pozdrav!


Many thanks friends! I will see those links.
Actually, simillar devices could be bought in almost every chinesse shops arround, based on one on chip device. But...i dont want those. I want same thing based on PIC and 2x16 or 2x20 inteligent LCD.Will keep trying...
Maybe that chinesse hyperproduction is main reason why enthusiasts didnt want to try to make it DIY...
Anyway many thanks!
