I understand how and why power factor correction is used, but what I'm not sure of is what effect if any would there be for over correction? (using a larger Capacitor load bank than is required)

I am trying to create a user interface (gui) that will display information that is being sent to a microcontroller. I'm not clear on what language the interface should be coded in? I know that some languages are very resource intensive, but I don't know the who's who. I was hoping to be able...

I need to find a flow meter that will allow me to program a low and high setpoint window, and turn on an output if the flow is not within the setpoint window. The flow is quite small. Maybe about 3 CFM The cycle time is about 15 seconds. And did I mention that the flow to monitor is vacuum...

I would like to get a couple of prototype boards made up. Does anyone know of a place where I can get these knocked off for a reasonable price. The board is 3" x 3" single sided with about 150 holes

Hi all, I'm playing with a new toy this week. I am looking for some small ultrasonic sensors. the transcever or the emitter/reciever pairs can be remote to the control circuit (if it exists). The specifics that i am looking for is: analog or digital feedback useable range of 0.25" to 60"...

Does anyone have, or know where one could aquire a schematic for a pneumatic oneshot?

I'm trying the charge a pack of lithium ion batteries, but all information that I can find thus far will only allow 1 or 2 cells in series at a time. Does anyone know of a curcuit that will allow 4 to 6 cells in serial?

I would like to connect a USB mouse to a microcontroller. Is the data transfer like a shift register where the all the data is sent in a specific number of bytes. Inside the packet each piece of info such as x pos. and y pos. are contained in a specific set of bits? This being said, is there...

How many different methods are there of controlling the fuel injectors? I am tinkering with building a fuel injection system for a small 2 cyl. engine. I was thinking of using pulse width modulation (pwm) to control the injectors. Is the the norm, or am I way off in right field here?
