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?
