Tried doing some searching, but didn't come up with much. I plan on using a kill key with my saber's recharge port, however I am not a huge fan of the Kill Key plugs that the store offers. I'd really like the kind that are offered on the Plecter Labs site, but $16 for a small thing like that plus international shipping kinda makes me shy from it. Any tips on possibly making a kill key from scratch, like what materials to use and such?
