Diy paddle key

I made my own key.

Push more for details

Found on the Internet a very interesting key design.

I decided to copy it and fit into my existing case.

Developed a key model that fit in the case.

Developed patterns for FR4 doublesided 1,5 mm. and 0.5mm

 

Cut out the details and soldered it together.

For better contact with the bolt, hit additional strips of bronze foil. Also I solder a spring.

Picked up in the case, fastened to double ducttape.
