Actuator Project ( Was MRotate4)
darthpaul:
Good stuff, too bad I only have big old CRTs to use(they were free).
DaOld Man:
Looks to me like you could be the first to rotate a CRT with one of those actuators. Are you up for the challenge?
darthpaul:
Don't you ever want me to finish my cabinet :dizzy:
DaOld Man:
Do any of us ever finish our cabinet? :scared
DaOld Man:
Sorry for the bump, but just in case anyone decides to build my serial port motor drive, I have found a potential problem.
I tested this drive on a different computer, and found that the inputs on that computer tend to float. This did not happen on the computer that I designed this circuit with.
So if you build this, I suggest you bread board it first and test on your computer.
It may be necessary to add 10K resistors from each input pin to the ground.
I would like to have input from anyone who has built this circuit.
Also, not sure if I already mentioned it, but the serial port, when the computer boots up, tries to communicate with any devices connected to it. This is undesirable because in this setup, it will make the motor jerk one way or the other during computer boot up.
I never found a way to overcome this, except to add a timer that allows time for the computer to completely boot before the serial drive gets any power.
