i used to use an excel macro, worked great. my company uses smart codes though, and they put access doors to all office areas... so if you want to leave your office area, you gotta take your smart card, which locks your computer as soon as you remove it. and if you forget your smart card...

AVR Studio from atmel http://www.atmel.com/dyn/products/tools_card.asp?tool_id=2725 you have to register to download (it's free). has an awesome simulator, as you step through your code it shows inputs going active/inactive and shows what each register is doing. pretty advanced stuff to get...

I don't remember ever having a book focused on a specific microcontroller, some basic assembly language programming books (or maybe even C), along with some general logic books explaining how the inputs and outputs really work would probably be a lot more beneficial. There's a ton of info on...

I need an oscilloscope... that 2 channel digital one is niiiiiiiiiiiiiice. I miss the 8 channel digital scopes from back in school. I have a bunch of breadboards, bunch of components, circuit board uC programmer, power supply and frequency generator. these are the basics for building and...

I'm assuming this is only good for completely desoldering a board, not just removing one component and replacing it? Seems like it'd melt away a large area of solder at once... very nice idea.

"spice" is whatever they use to simulate circuits (the algorithms or something), alot of people have programs to lay them out then run the spice simulation on it. Linear offers LTSpice for free and constantly updates its parts: http://www.linear.com/designtools/software/ i used orcad in...

if its a 120vac lamp, get a relay rated for 120vac and wire it through the normally open part of the relay (the terminals will be NC, NO, and C, put the neutral leg through C, and the hot leg through NO), then wire the 12vdc brick through the control side of the relay. when the 12vdc is...

if its a 12vdc light, get a relay rated for 12vdc and 500ma or whatever the transformer says, again, this will work perfectly with automotive relays since cars are all 12vdc. get two 12vdc transformers, plug one into the strip, one into the battery backup, wire the one into the battery as...

Really you can't find a better jumping off point than the recommended cmoy amp... it's completely 100% documented on how to DIY, full parts list, etc. http://tangentsoft.net/audio/cmoy-tutorial/

www.jameco.com look under ac-ac wall power supplies.

jameco.com is another good source. more hobbyist friendly than the others last i remember too.

The two middle wires are common, then one side is +12volts and one side is +5volts. so.. pin 1 = +12volts pin 2 = common pin 3 = common pin 4 = +5 volts the connector should have a notch that sticks on on the bottom of it, that notch falls right between pin 1 and pin 2. so connect...

big 4 plug connector, same type you plug into IDE hard drives, plug it into that.

It's usually written on the power supply somewhere, even if it's internal.

GPS units, especially before USB was an old standard, often used proprietary connectors... it might not be anything standard you can buy from anywhere. Try ebay for the cable?

Hakko 936 or a knockoff of it is a solid choice.

i tend to walk around while working on a computer to grab different parts, wearing a wristband would just be kind of an annoyance. i always make sure i touch the metal of my case before touching anything and try to always keep contact with the case anyways for grounding. i wear my wristband...

they sold 28 billion last year and had like 45billion in assets (according to forbes)... it's an extremely large company that dominates data centers everywhere. any serious networking probably involves cisco, and if it's not cisco, it's a mimic of cisco... so a ccna should do you well no...

cbtnuggets are golden... they're absolutely awesome videos that walk you through everything. little slow if you already have a good idea, but if starting from scratch, they're a good route to go.

there's no swishing in my loop either. i can watch some water move around a bit in the reservoir but i don't hear anything..

i live and die by the "For Dummies" books... pick a few up and get to reading.

I always compare it to fans in a house. Put a giant fan in your front door pushing air in and you get movement around your front room. Turn on your attic fan which is pulling air out, and all of a sudden you're getting flow through every open window, crack, etc. in your house.

thermochill is weird. for a swiftech, pulling works alot better. i actually mounted one fan pulling and one pushing on a rad and the one pushing didn't do to much. dangerden also recommends pulling out and they're radiators are very similiar to swiftechs. the whole suck/blow debate...

A reservoir or a T-Line is used for filling the system, emptying it, bleeding it, etc. The advantage to a reservoir is it keeps water in your pump (normally running a pump dry = bad bad news. NEVER do it), and it bleeds faster (by bleeding, we mean it gets all the air bubbles out of the...

if they're running off a seperate power source, they obviously want you to turn the pump on first before turning on the comp so you don't forget. if the pump is running off the same power supply as the rest of the computer, then it's good to go.

off topic: nice snorkel

my 5mW won't light anything... it's pretty safe. I thought 5mW was like, the legal limit or something... but now i'm intrigued.

creepy looking.... but the thing has a good center of gravity which i find to be amazing.

Rock your case around and see if you can get the bubbles out... not good to have them in your loop.

i always pull out. the closet thing to an exception to that would be fans over specific areas that i want airflow too. (ie: my harddrives. pretty much everything else is on water). if you put a giant fan in your front door and started blowing air into your house... you'd get air movement...

I'd go res --> pump --> cpu --> gpu --> rad --> gpu --> rad the only thing that really matters is res before the pump. plenty of people claim that order of the loop does not matter one single bit outside of that, becuase eventually the loop will reach a tempurature that the whole loop will...

The forum faded off when it was taken off the main list and tucked away under case modding I think.

I don't see many good projects anywhere anymore. I think everyones with gee, we've all gotten old and other stuff takes up our spare time nowadays. :(

you can spend like $25 on a set of molex tools which um... i have no idea how they work cause i've never seen anyone actually buy them. just wiggle them

My companies actually sponsering a high school for this, I was asked to help out but was given to short of notice for the massive amounts of time commitment it takes. Looking through what they've got, what they did last year, etc. it all seems like very interesting stuff. My company and a...

This is an awesome site. Active with alot of very intelligent people on it for anything electronics you really want to do.

get a step bit like this: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=96275 Makes a nice smooth hole... like it was professionally done. Just keep going in until they fit snugly. This is what I did using the same gromits from petra's but I forget what I ended up at...

I think you need 10 ramsinks and 1 mosfet heatsink to cool the 8800GT... paying $40 for the Swiftech MC8800 SMC Cooling Kit is a bit of a ripoff. Also 4 of the ramsinks will need to be low profile sinks to fit under the MCW60 water inlet/outlets... either that or you can cut down/file...

You should be able to put both gcards on the same loop and use only the one pump. The rad is what has the biggest effect on cooling probably, with that tripple rad you should be just fine. Looking at what other people are getting with similiar SLI settups to you, none of them are breaking...

If you add a second pump for the second GTX, you could also add a second rad like the MCR220 and just put it on a second loop. Doing that the second pump could be much smaller - like an mcp355. Wouldn't need a res you can just do a T, put two low speed yate loons on the second rad and you'd...
