    Ball Firing Canon

    well! thanks for the help ante! i want to go for the mechanical side only. now in the earlier thread, i remeber that i asked you about an idea of displacing the ball in the tube one by one. BUt this time, i want to fire them to a certain height above the canon in the form of a projectile. Just...

    555 monostable Operation problem

    Hi guys! well! im using 555 IC as a monostable multivibrator. What im using values are R=690kohms C=10uf and i have connected trigger pin i.e. pin2 to the ground. Now i think when the circuit will be on, the pin3 should give me a pulse of width around 5-7 sec and then the output on pin3...

    urgent!help please?

    HI R2 sorry for late replying, well! there are a no of options u can go for. First one recomendation of mine is this that you should Use MOSFETS for Hbridge. They switch a lot faster and are easier to control. By using MOSFETs, you can have a no of driver options. Like you can use MAX621, a...
