I am in need of bipolar power supply that is +/-5vdc to work with an electronic device that is not important (thus I'm not worried about frying it). I was wondering if it would be possible to get two 5 volt adapters and wire one into the +5v circuit and the other into -5v circuit with the corresponding -/+ wires going to ground? [more inside]

Need some advice please.
I tried to install a new Power supply in my 2 year Old Dell PC in anticipation of installing a new Hi Spec Graphics card. Did all the necessary connections (I think) except connecting up the Sata cable to the Optical Disc drive (It wouldn't reach, I'll come to that in a minute).
Powered it up, nothing. I noticed a light came on, on the motherboard (so It's getting power right??)
Took out the power supply, refitted the old one and it all works.
1.Does not attaching the Sata cable to the optical drive matter??
2.Can I buy a Sata cable extension??
3.Is the light (showing on the motherboard) indicative of the Power supply working??
4,Is it possible that the new power supply is not functioning???
5.Is there something really obvious I'm missing??
Any help advice would be gratefully accepted, thanks

Received a replacement power supply for my Powerbook G4 today. The Apple power supply stats are "Input: AC 100-240V 50/60HZ 1.5A Ouput: 24.5V === 2.65A" The replacement supply reads "Input: 100-240V ~ 2.0A, 50-60HZ Ouput: 15-24V === 4.3A & 75W MAX". Is the new power supply incompatible with my Powerbook? [more inside]

My old laptop blew the motherboard after 3 years of great use (Acer Aspire 5670). I just bought a new laptop (Acer Extensa 5630Z). Can I use the power charger/AC Adapter from my old on my new without doing damage?
The new one is rated 19V 3.43A. The old one is 19V 4.4A. (plugs are the same). Long live the hive mind!

Does anyone know of a company that makes a single file drawer? I mean in metal (or some other sturdy material, ie. hard plastic) like a file cabinet but with only one drawer. I found this
, but this is carboard, so not good for my purposes, but the form is perfect. I've searched and searched on the internet and I can't find anything, but it seems like something that should exist. Can anyone help?

I'm trying to find angle iron uprights for industrial shelving. My small non-profit was given shelving (well, shelves) that we originally expected uprights to come with and they ended up without the uprights.
I'm looking for angle iron around 8 ft(96inches) long, of reasonable strength, and with bolt holes running the length. Holes on the shelves are approximately 3/4" on center from the corner, but are oval.
leads are appreciated as my google-fu has mostly failed me. thanks.

I'm taking up welding as a hobby and was hoping someone might know of a good metal supply shop that would be a open to hobbiest (i.e.: they are willing to sell small quantities and have weekend hours). I find that home depot and lowes offer a limited selection of steel, so it would be nice to find a place i can buy mechanical tube steel, small gage pipe, and other misc steel.

Electronics filter: What can I do to make a 24v PSU turn into a 18-19v PSU? It's 0.5A power supply which as far as I can tell is important to know when using, say a resistor to lower voltage. But how resistant should the resistor be? I've found information on how to tell a resistor's value, but not how it will actually effect a line's voltage or how to calculate it. Are there any good sites with this information? Also what will happen to the amount of amps the PSU supplies when I do change it to 18/19v??
Also, what can be done to increase the amperage of a power supply? What inside the circutry is actually dictating the amperage?
