Here, I will post the link here as well. Weeder Technologies When I originally found the Weeder Site, he had an option to buy the boards as a kit. He seems to have dropped that option. |

Well? did you get it working? don't leave us all in suspense! ;D |

Sorry for the wait, I've been sick! |

Good job. I don't know anything about the IPAC but generaly if you're too high on the current the resistance in your load is too low, it acts like a short circuit. So it can't be good for it. I wouldn't worry about the relay. I assume he was conservative in his maximum but you're way over. Driver boards usually have a small transitor first then the large transistor so they step up gradually in current draw. I haven't done anything with the parallel port yet, I've been busy writing Z80 code and manufacturing circuit boards for my Ms Pacman project. I might see if I can find the source for it though. Maybe someone who's worked with parallel ports before will work on it. It may not be that difficult, but I haven't hooked up an led to my port yet so I can test. Dave |
