Elektor had a projekt that did just that. Check with them for a reprint maybe or if somebody here has it? It had a sender and a receiver.

Smile Elektor Phase Control Projects.

Remember that these numbers of edition can differ
because swedish edition of Elektor comes 1 or 2 months
later than the original.

Phase indicator:
Generator have line out or a little speaker.
Receiver have line in or an electret microphone.
In or out of phase is indicated by 2 different LEDs.
This was in Elektor 11/90 (#11 1990, Sweden)

Phase Meter, a pecision instrument. Digital display.
10 Hz - 20 000 Hz, 0-360 degrees, fault 1,2 or 5, depending on timeperiod, max 10 seconds.
Input 0.006 mV - 100 Volt, 1 Mohm
Elektor 6/91

Phase Meter, low price. Digital display 0-360 degrees. Impedance 1 Mohm.
Elektor 6/93

Simple Phase Meter. Impedance 1 Mohm. DC-voltage output for Digital Voltmeter showing the phase difference. Does not show which channel is before or after.
Elektor 1/97.

All 4 projects have PCB-layout.

I wish I had a scanner. But someone else might have.
When I get enough money over, I will buy me one.
A good one!

That's a disgrace that they didn't remember and they are the ones that publsihed it...
The one in #11 Swedish is the one and that project was in the English one as well as I bough only English editions at that time and I remember it clearly and I think they even had the front panels for the project.

See if you can get somebody to scan it as I think it is exaclty what you want.

Even I would like a copy since I threw out all my complete years of Elektor since 1983...
