I would say, that since you know nothing about how this value was derived from the manufacturer, the only way you are going to get useful data is from a meter. If you really want genuine numbers on this, you are going to have to wire it to a multimeter. I would say that the power rating...

The rating is for the "Maximum Draw" of the device. There is still internal resistance in the motor coil, even when there is no load. There is also a high load during the acceleration of the drive shaft, as there is a 'load' during that phase. Get yourself an ampmeter and measure the current...

I say if you want it to discharge faster, go with a higher wattage wire coil resistor. Something like a 10 W 50 Ohm.

There are many tables out there for the current carrying capacity of wire based on its gauge. If its area is 1.5mm^2 that puts it some where in between 15 and 16 gauge wire. Here is an example table. http://www.engineeringtoolbox.com/awg-wire-gauge-d_731.html Obviously this depends on how...

I'm concerned about the fact that you are talking about using a 3 ohm resistor for a 12 v circuit. I think we need to know more about the sensor that you are talking about. What does this sensor read? Its quite possible that the resistor will catch on fire as the previous post warns about...

Thats great to hear. The whole crystal radio thing really had me thinking . . haha

Wouldn't limiting the partition size be essentially the same thing? I mean, if is a 500GB drive, and you set up a partition that's only 100GB, wouldn't this be similar? The only difference being that maybe you wouldn't have control over where the data is being stored on the platters themselves?

I've heard that there were ways to structure the data on the platters that would result in faster seek times. I was under the impression that the inner region was the fastest, but I could be wrong. I've never heard of being able to actually limit the locations on the platters where data is...

So I'm building a new workstation right now, and by no means is this the first time. The board is an ASUS P8P67, and the CPU is an Intel 2500k. I plan on running the OS off of a RAID0 array. I image my OS partition on a regular basis, so I'm not worried about being in RAID0. My question is...

You can download a signal generator program. That would let you output various waveforms from the computers audio card. Depending on the type of scope you could also try to pick up the RGB sync signals from the computers VGA output. There are a lot of things you could look at.

You need a switching power supply. Its not going to be an easy thing to do.

It looks like the device you found can do what you want. What sort of software will you be using to control the switch? Does it matter? What type of computer will you be connecting it to? There are countless ways to do this. You basically just need a computer controlled relay switch.

In my opinion, the TI-89 is the best calculator ever made. Very much worth the price, and it can do anything you will ever need to do in terms of math. A wise choice.

I am personally a big fan of the TI-89. I've owned them for 10 years, I have one sitting on my desk right now. The newer ones (Titanium Models) have a nice USB interface for uploading programs directly to the calc without having to use a serial port. I do think that its about time that Texas...

Some of you may find this interesting. http://solarroadways.com/main.html I came across this project maybe a year ago. This is an Idaho based company that is developing solar highway panels. They are basically solar panels that you drive on. It makes a lot of sense, watch the video's on...
