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.

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?

New Earth Time (NET) digital clock in recycled retro-modern case

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.

Addressable Milk Bottles (LED Lighting + Arduino)

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.

Arduino Laser Tag - Duino Tag

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. 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.

Twittering Laser Tripwire with Webcam Capture

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.

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!

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. 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.

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.

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. Make a Secure, Lock-Free Box for Your Prized Possessions. How to Ergonomically Optimize Your Workspace.
