I would like to use blender PSU board.
To power motor of the blender. Whole blender consists of this this board, control board (which blew up) and motor itself. I am now trying to hack this board to output power and use arduino (with some mosfets) instead of control board.
I know this is some kind of AC to DC converter (the motor itself is DC, I powered it with my Lab bench power supply and it spinned). I tried to trace all connections with multimeter and found datasheet (LNK362-364) for chip between diodes (left bottom on the picture). All I was able to get was a DC voltage jumping from 2V to 30V, measured from LNK's pins (pin 5 and 7). I imagine that is rectified sine wave (but I don't have oscilloscope to prove it). I wasn't able to get stable DC from this board, I guess I have to plug somewhere around these caps, but where to get reference point? There is transistor under the white goo, I guess it could serve a safety feature for the board.
The pins on the top was where the control board was connected. I tried to measure, connect them, but with no luck. I am kinda lost now, where should I go next, to obtain power from this little device.
