As The Bodger suggested, have you tried running the PC without any of its bits? i.e. take out anything that isn't absolutely necessary (NIC,...
surely it would be simpler to just run piping from the dehumidifiers to wherever you're planning to drain the water? You're going to have to run...
a purely chemical detonator can be made by mixing potassium permanganate and glycerin, both of which are available from a chemist. Without going...
out of interest, have you tried filtering your mains power? Both to the PC and to the speakers? The PC PSU should filter all the nasty out, but...
Of course, you could just use an op-amp adder circuit to add the signals... see a circuit diagram here ('cos I'm too lazy to draw one) - note...
You would need to make a power supply, since although you can pull -12V from your PC PSU, that's generally not a good idea. This is really easy...
It would be much simpler to have a single machine that controls access to the internet (i.e. a gateway or bridge), which basically does...
that sounds like a hardware problem? Have you tried with another video card? Which card gives the error when you try to start it? What version...
I had a similar problem with my onboard SiS soundcard, when I hibernated windows. After I'd hibernated and restored a few times, the sound would...
check out the main bit-tech page as I'm fairly sure they must have reviewed some power supplies in the past. Tom's Hardware has done loads of...
Have you considered using a remote access control-type setup, where you have to go pay a cashier to be able to use a PC - essentially, a gateway...
Perhaps a little too late to be useful, but have you considered using several layers of plexi and just etching where you want the 'lights' to be?...
going on from what smilodon said, a 7909 would do you nicely. Add in a 7805, and you have everything you need, all from a 12V line. Alternately,...
Cue TheAnimus, our resident PIC fanatic :cooldude: :hehe:
Cars provide plenty of oomph from which to generate the requisite voltages and currents for a PC - bear in mind that starting a car draws...
KVMs are generally ok, since they do things like disconnecting the power before anything else (i.e. like USB does). Just pulling plugs out of the...
umm...guys, PS/2 is NOT hot-swappable. Most motherboards have protection built in these days, since folks insist on pulling out the keyboard and...
mm, good point. I'd throw my vote for the 555 option, since it's super-simple, but loads of versatility. Low current consumption, too :D
Heh, see what happens when too many people are reading (and replying to) the same thread at the same time... Actually, if you read back, I...
Yes, since IDE is not inherantly hot-swappable, you would need to make sure you only connect or disconnect drives while the PC is powered down, if...
Separate names with a comma.
