| - I did not find a suitable wall socket enclosure or similar - this is just an estimate. The cost of this part heavily depends on the number of devices to be manufactured. I hope to find an already available enclosure and tailor the PCB to it. | - I did not find a suitable wall socket enclosure or similar - this is just an estimate.

| - The power supply is still an open issue. The power consumption of the circuit is pretty low, around 20mA. The driver for the relay needs more power. Is it possible to generate 3.3V directly from mains? | - The power supply is still an open issue. The power consumption of the circuit is pretty low, around 20mA.

| + | Hint: Perhaps you will find a solution here: http://www.powerint.com/sites/default/files/product-docs/an37.pdf | ||
| + | To trigger the line-relay you can use a solid-state-relay: http://www.sander-electronic.de/be00045.html | ||
| + | Or you use a SSR directly as line-switch, but then you have no line-seperation. btw. the finder relay is obsolete. mfg Udo | ||
