  1. i was waiting for this :)

    the instructions seem to be pretty clear- i missed the circuit diagram the first time round, but it’s clearly there and seems to make sense. I wonder how much power the reload relay draws though, and whether a slightly more complex solution would pay off by increasing the battery life. i’m deeply tempted to build one just as an electronically controllable coil gun.

  2. Well thank goodness that Vennessa is here to helpfully point that everyone here so far appreciates this hack. And thank goodness that she she herself isn’t wasting space with her post. I’d hate to think what we’d do without it.

    Will, nice job! I’m gonna have to try this one!
