The machine has a small micro switch under the lid of the machine that is either stuck or bent. Remove the top and look in the area of the bobbin winder and flip the winder to engage and disengage. You should see a swith that the bobbin winder pushes against. That should be the problem, if it is bent you may be able to straighten it out.

Hand held scanner to open a box?


If you were to have it open using any barcode, you could build a circuit that uses the beep of the scanner when it reads a barcode.

If you wanted it to only work with specific barcodes it would get far more complicated, you could right a program that displays a white or black box in a corner of your computer screen and just build a simple light detection circuit and tape the CDS Cell of the circuit on your screen where that box gets displayed.
