Series Circuits OK, you should know that electricity needs a completed circuit to flow, or a loop if you will. however it doesn't stop there, there are two types of circuit you will need to know and those are Series and Parallel. A Series circuit (pictured below) operates like a race track, one continuous route for the flow of electricity to take. the images below show a simple circuit where a battery is connected to two lamps, this is a series circuit as the two lamps are connected with inverse polarity.
Ever get confused by GMT, or just wish you had a cooler way to keep track of time? Build a New Earth Time clock! Using a PIC microcontroller, some code, and a couple discrete parts, you too can have a unique timekeeping device to keep on your desk. New Earth Time (NET) is an idea for a global time standard. Like Greenwich Mean Time (GMT), it is the same "New Earth Time" everywhere on the globe at any instant. New Earth Time (NET) digital clock in recycled retro-modern case

Make PPE milk bottles into good looking LED lights, and use an Arduino to control them. This recycles a number of things, mainly the milk bottles, and uses a very low amount of power: the LEDs apparently dissipate less than 3 watts but are bright enough to see by. Among other things, I wanted to see if I could make an electronic light feel more human friendly than most, and found rotary controllers are a good way of doing this. PPE milk bottles make for a cheap yet aesthetically pleasing way to diffuse LED lighting. Especially if you can find nice round ones :) Modding an object with LED lighting is not only environmentally friendly, but also much more straightforward than building a housing from scratch.

Arduino Laser Tag - Duino Tag Duino tagger- General introduction Duino tag is a laser tag system based around the arduino. Finally a laser tag system that can be tweaked modded and hacked until you have the perfect laser tag system for office ordnance, woodland wars and suburban skirmishes. Laser tag is combat game like paintball or airsoft without the pain, it uses infrared light (IR) to simulate the tagging / shooting of other players or targets. I have been working on this project for a while, but don't see it as over, I just though it was time to get more people involved. Hopefully this instructable will be near enough finished in time for me to enter it in the arduino competition, although I expect the instructable will need editing and tweaking for some time to come.
This instructable will show you how to construct a laser tripwire that can twitter and grab an image from a webcam, as well as execute any command you can put in a bash script. This instructable is actually quite simple and is even suitable as a beginner arduino project. It requires a GNU/linux (or possibly Mac) operating system with the arduino IDE and Processing IDE working properly. This project could also be implemented in Windows if you created a more complex processing application.

Hack Attack: Turn your $60 router into a $600 router Got this to work on the WRT54G v8 (will work on 7 as well, just replace the one file with the corresponding 7 version): First of all, use IE explorer. Firefox didn't work at all on this for me, even after install.

This Hands Free Water Station is Perfect for Camping, Backyard Playgrounds It's...a standard 2.5 jug of water. You can get them from any grocery store and carry it with one hand. I've learned, through lifehacker, instructables, and similar sites, that people often have very different definitions of camping. For me, camping always involves a bit of a walk/hike into the wilderness so that you're far, far away from cars and civilization and have to boil/treat water to refill canteens.

How to Turn Your Computer into a Retro Game Arcade While I've never heard the term "freezes" for save states, they are a very useful feature. However, a word of caution — be careful to not overuse them. They can really cheapen a game if you use them too much. You start out just using them to make saving and loading a little bit faster, but before you know it, you're saving in times you have no business saving, like in the middle of a long RPG battle, just redoing any mistake you make. It's really tempting, believe me, but try not to use them to the point of basically cheating in a game.

While I might not care about protecting pliers this much, I do worry about my camera and it's lenses. Not aware of this, I bought 1x1" pick apart foam blocks which worked pretty well, but it came in at $15 per block and it took two blocks to handle one camera case. Unfortunately I've switched my kit a bit since then so it's already sub-optimal. This looks like a damn good idea for things like that and $4 per can is a lot more appealing than dropping another $30+ shipping.

Rollerblading In These Salt Mine Tunnels Is Like Entering the Death Star in Return of the Jedi No stick in the mud. That was exactly my first thought, especially when he jumps to turn back around. Luck he didn't wack his head on the mine ceiling at 30mph or whatever he was doing. he went fast in a seemingly very clean environment, and around one corner.. dude looks like he knows what he's doing, and can handle going around one corner without falling down. its his own right to go bust his ass and get hurt. people complaining about safety and suing others for their own dumbass decisions is the reason this video is remarkable. otherwise it wouldn't be such a big deal for people to go around doing this stuff all the time.
I want to put wireless speakers in 5 places in my house, but I don't have $900 to throw down for 5 squeeze boxes. What do you suggest as an alternative? Or are you just a shill for logitech? Wow, that's a little harsh. If you don't have $900, then you're not going to be able to put together the hardware necessary to build the wireless side of your five speaker system. $900 would get you the controllers, encoders and wireless for your five setup, but you would still need the speakers and amplifiers. The Logitech system would actually be cheaper. Build Wi-Fi Speakers to Stream Music Anywhere
