I am looking for a cheap (under ) AC/DC Power Supply with the following specs:
Input: Should be in the 60Hz range and a volt range that includes 115VAC
Output 1: +12v @ A => 3A (equal to or more than 3A)
Output 2: -12v @ mA * (amout of mA doesnt matter)
Output 3: Regulated +5v @ => 1.5A
Output 4: Regulated -5v @ => mA*

I know the people into electronics are gonna say "That price is unreasonable" So some links to surplus stores or even schematics would be nice.

In case anyone feels that I don't need these requiremens here are the main parts in the design the power supply will be used for:
1 +5 volt NE556
1 +5 volt 8Pin PIC
2 LED
1 38KHz Detector
1 highpower MOSFETS and a couple of transistors
1 +12 volt DC Motor\ Amperage req are unkown but are likely under 4 amps, as it is from a Milwakue cordless drill

So with these specs, are the two negative outputs even required? Or do I just need the two positive outputs and a GND?

Thanks in advance, sorry about the length of the question.
Geez! that Raidmax KY-550ATX Hybrid PSU is a bute! But please keep the answers comming.

Okay, I cannot afford a good cordless drill, so now I am looking at electric (corded) drills. I'm sure that the same things apply to corded drills as to cordless drills. However, on corded drills it appears that the power is measured in amps rather than volts. How many amps do I need to drill through wood and seat crews without stripping them? I went to Lowe's and see that an 8 amp Dewalt corded drill is .00 dollars as compared to an 18 volt Dewalt which is approx. 0.00. I know corded is not as convenient as cordless, but my budget is .00, (so I also need to think about the cost of an indoor/outdoor extension cord.)
Okay, now I'm confused. Dan H says that his Ryobi and Black and Decker are used in daily construction, which I assume is pretty heavy and active use. However, other people are saying that Ryobi's and B&D's have plastic internal parts and won't hold up. Which info. is correct?

Im looking a 2 different drills. A cord drill with (6.5 amps) and a cordless dill with (2.5 amps). What is going to be the operating difference between the two?

Years ago I bought a Craftsman Professional corded 1/2" chuck drill. It was almost like a cordless drill with a cord instead of with batteries. What I mean is that there was a High and Low speed switch on the top of it. When I needed to drive lag screws into a post, that sucker did it with ease. It was really wonderful. I don't remember if the tool got lost or broken.

I can't find a drill that features this anywhere today. Does anybody have any ideas? Craftsman does not appear to carry that drill any more, as if it was a limited edition or something. I just can't believe that the High/Low speed switch (not a variable speed trigger, but a switch that changes the torque abaility) isn't found on any drill that is more than 6 amps. That feature is so amazing.

Need to get a replacement charger for my black and decker 12v cordless drill (CD12OS) but I can't find how many amps.
Doesn't say it anywhere on the drill, battery, or in the manual.

I have a Milwaukee cordless screwdriver.
The charger lists Input at 120v AC, 60hz, 100mA : Output at 2.4v DC, 1.4 amps
The battery says 2.4v 2400mAh (Ni-MH)

Why do both the battery and charger get so hot (almost too hot to touch) when charging?

It's a cheap Black and Decker cordless drill, 18v. I would like to know what voltage tolerance it has(can I use a 15v power supply, how about a 24volt power supply?) and would like to know typically how many amps these cordless drills use under full load.

the Batteries are shot basically, and I can't find a corded drill with the cordless features(torque settings etc.) so I wish to utilize these drills I have laying around, I was looking in catalogs and seems to me a good power supply I can find is a 15v with 10 amps continuous or a 24 power supply.

I hooked the drill up to my ex-tech variable voltage 3amp 0-30v power supply, my current limiter would keep tripping and can only screw a deck screw in about half way....

What would be a good power supply for this application, and I can't seem to find the watts the tool draws, so I am not sure how big of a supply I need, or the voltage.

I am building a small solar powered machine (barrel tumbler) and would like to power the drive motor (salvaged from a cordless screwdriver) with solar cells. In order to keep the duty cycle on the motor low I would like it to operate only under full sun. If I wire a zener diode in series with the motor with a breakdown voltage slightly less that the solar cell arrays output in full sun will that work? I would like to avoid using a battery, charge controller, and timer circuit to regulate for simplicity and cost purposes.
I had planned on using a 3.6V cordless screwdriver motor and gearset to turn the drum. I figured the startup amps for the motor could be determined with a multimeter and then the solar array sized accordingly.

I know zeners are typically used in parallel with a voltage source as shunt to regulate voltage but in this case I'd like to try using it in series to only allow current through in full sun.

Don't really have any specific numbers yet as it's beeing planned and specific components haven't been sourced yet.

Based on your response, the voltage drop across the zener would be 10Volts. I thought when they broke down they were essentially a short, which is why I'd like to wire it in series.

Power wasting is not of concern as the the device is to turn the drum a bit once an a while so I don't have to do it manually....because I'm lazy and forgetful. I suppose if it shortened the life of the diode I would be concerned about that.
the best I can do on the numbers is that the array will be series up out of 0.5V cells to get around 3.6 volts and then paralleled up to get the required current. the actual wattage expected wuring operation through the circuit would be on the order of 2 or 3 watts, 5 at the most.
