I have uploaded the circuit diagram. (If there is anything wrong with the diagram i will be sure to upload a modified version

| Jul 22, 2015 at 13:51 | comment | added | Curd | There is a mistake in the schematic at the + input (pin 5) of the the second OpAmp (U2). One of the three resistors at the + input is going to GND, one is going to Vcc and one (R4) is going to the output. It works as comparator with hysteresis (i.e. Schmitt-trigger; pos. feedback is via R4). | |

cropped the images

| Jul 21, 2015 at 9:27 | comment | added | PlasmaHH | Please use images cropped down to the necessary, that makes them appear bigger within the post without having to open them externally. As others have mentioned without a schematic it is even more guess work, so help us to help you and quickly draw one. | |
| Jul 21, 2015 at 7:38 | comment | added | Curd | Drawing the circuit diagram would help. The PCB is quite simple, it has not too many parts and is one sided so it's easy to do. | |
