    TTL Buffer

    kabilan, The ULN2803 will buffer the port just fine. Limiting the port pins with zener diodes to ground will also protect your parallel port pins. If you are only connecting to LEDs, you really do not have a worry, though. Just use the correct resistor to limit the current. MP

    Sheet Metal Bending

    Rhonn, You might want to try your hand at casting aluminum. I know many guys use styrofoam in their sand mold because the styrofoam will melt away when they pour the aluminum onto it. Not as hard to make a mold that way, I guess. Perhaps Dazza can give you some good tips. He is the expert, I...
