Hack Your Wii, Eat Well on a Budget, and Survive Your Less-than-Perfect Job. 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.

Series Circuits

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. This is why we use resistors, to "absorb" some voltage (and current) to protect components. now if the components are different then the voltage is distributed accordingly. say i have a blue led and a white led, these are connected to a 5v source in seriesthe blue led runs on 3v and the white on 2v. this scenario would be fine as both the components voltage requirements are the same as the source and there would be 3v across the blue led and 2v across the white led.

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. 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 Hands Free Water Station is Perfect for Camping, Backyard Playgrounds

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. For others, camping involves setting up a tent right next to the car. And for others, it's sleeping in the rv at the campsite, or even sleeping in a cabin.

If you're like me, this makes little sense. And if you're a desert or beach camper, well, then the "bigass" jugs of water aren't really optional anymore; you bring them or you're toast. I have those for when I take my boat camping and we stay on the islands, the launch has a water pump and we just fill the jugs up there. Build Your Own Grid-It Tech Organizer in a Vintage Book. No!

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. I've actually switched over more to emulators on my Wii partially because of the fact that saving and loading save states is slower and less tempting. But yeah, nice guide. Oh, and one last thing — having played on emulators for at least a decade, I don't even know why you put the section in on using a keyboard.
