I will not import the steps here because I believe the PCB hack is much better and nicer. The complete instruction set for reed relays is still available on github though: https://github.com/Psychokiller1888/snipsvelux/wiki

Are being written and tested at the moment with beginners to ensure they are understandable and readable. If you don't feel like creating your own pcb and/or do the soldering, you can contact me, I don't bite.
