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.
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.
New Earth Time (NET) digital clock in recycled retro-modern case. 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. LED chandelier. 1.

Frosting spray 7. Small cable ties 8. Tools: 1. Addressable Milk Bottles (LED Lighting + Arduino) 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.
This instructable will deal mainly with physical design and production, and I'm going to assume you have a basic knowledge of creating electronic circuits and LED lighting. 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. Twittering Laser Tripwire with Webcam Capture. 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. Hardware RequirementsArduino Board Laser pointer/pen Light Dependant Resistor 100Kohm Resistor Optional: Webcam Breadboard. The "Introduction to Arduino" Comic Makes It Easy to Get Started with Electronics Hacking.

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. Build Your Own Grid-It Tech Organizer in a Vintage Book. No!
NOOO! As cool as this may look, I just cannot do this! I love my books too much. Make Your Own Grappling Hook Launcher for Extreme Tree Climbing, Crime Fighting.

Hack a Stereo Jack Into a Bluetooth Headset for Wireless Streaming. 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. 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. Build a DIY Photography Ring Light from an Ikea Chandelier.
Make a Custom Form-Fitting Case for Your Tools or Precious Gear with Foam Filler. 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. DIY Lightweight Backpacking Cooler.

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. Build Wi-Fi Speakers to Stream Music Anywhere.
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.
