Hi, I need to operate a 12VDC 2-wire PM motor in both directions. I will be interfacing it through a microcontroller. What i am asking is if there is an IC that operates on 5V and can control the 12V (and polarity) that will control the motor. Or is there a method anyone can suggest with maybe...

Im looking for an IC that i can run off of 5V DC from a microcontroller to control the on/off of components that will be using 12-24V DC to operate. I was just going to use one transistor to control another transistor/scr but i know there are more "up-to-date" methods by using IC's. Can anyone...

Hi, A friend of mine has been recently given an old non-operating payphone(i think its a bell one from the late 80's, havent seen it yet.). He want's to restore it and hang in in his home as a fully functional phone. I'l be helping him restore it. The circuit board for it has been snapped so...

Im looking for some insight on controlling a dc motor and also a couple of 12V actuators with a microcontroller. I need some help with how exactly i can reverse the polarities automatically to reverse the direction of the motors. Is there and circuitry that can switch the directions of motors...

Hi, Im looking for parts such as servo-motors, actuators, small conveyer components, etc. Anyone know i good site for these type of components?

Hi, Im looking for information involving a robotic arm. I want to build a robotic arm that can rotate, raise&lower, and clamp and retract a claw. I want to use a microcontroller to control it but i would appreciate any help on where to find information on building an arm, what parts i need...

Can anyone help direct me in the right direction for help with regards to using Scanner/Adapter mode. Maybe some site that has a good overview of how it actually works. Anyhelp would be greatly appreciated! Thanks

Does anyone know any good links that can go in depth with plc commands like rto's, resets, latches, ton's etc.?

Hello, I'm trying to determine whether i need 2 load break elbows on a single phase pad mounted 28kV/16kV transformer with an open point. The transformer is one of many in a subdivision. It is at the end of a run and is not connected back into the phase to create a complete loop. The company...

Hey everyone, Just a simple question that i cant figure out! When you create something in model space on the model tab, how do i get whatever is in the model tab to NOT show up on the layouts i create on the same drawing. I want to use view ports to show sections of the model drawings but i...

Hey Everyone, I just got a job in a hydro company and im in the engineering department and im mailnly doing design and drafting work with autocad. The drafting is not a problem but there are a few problems with the designing. Can any help me with a few things? They use colours such as...
