Mine means my design, I am not selling anything, I freely gave the schematic and prototype layout.

2 plugs (you hate)
1 perf board 3.00
1 390 chip 2.50
1 5 volt reg 2.00
1 resistor .50
1 cap .50
3 wire 4.00

less than 30$, now if you could come up with a higher voltage divide chip it could be wired right to the chip and then potted. and your correct loose the connector and this thing would be lots cheaper but then if something goes wrong it would not be as easy fix, pull it out and just plug it in back to stock.

and quit shooting trash cans they leak when you do that!!!!
