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. I would kill me to do this to a book, even if I owned several redundant copies of a book that I absolutely despised. Wouldn't someone enjoy reading them? Say I actually went through with this, probably under deep sedation, then what would I have? The only way I can see myself going through with this would be to find a book that I so thoroughly DESPISE that I would want to carry around with me for the rest of my life a perpetual reminder of the eternal spite and loathing that I have for that author and his or her lump of inestimable drivel. Then, in the tears of the vanquished, I would see my own reflection and despair for the irreperable harm that I've caused to not only another book - but to a fellow book lover. No, Melanie Pinola, I cannot do this.
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. 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. One of the FB commenters to this story had a suggestion that might work well for you, since you hike.
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. This instructable aims to provide you with the information you will need to go out and build your own duino tagger. This instructable does not look in too much detail at the software / code side of the project, although a working code based on the miles tag protocol is provided. For those wishing to learn about duino tagger programming I suggest you start at the excellent tutorials found at A Terrible Idea. Youtube videos of my duino taggers:
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.
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.
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. If you're calling him a shill for suggesting Logitech, I'd hate to see what sort of language you'd be using if he suggested Sonos. Sorry, I used to be in Internet Marketing and I'm just extremely skeptical these days when someone suggests one item and has a link to it.
How to Ergonomically Optimize Your Workspace Random bits: If you wear multi-focus glasses (bifocals, progressives), I'd suggest you want the monitor lower than all the standard ergonomic diagrams show. Essentially, you want your neck straight, eyes angled down to look at the monitor through the "close up" part of your glasses. Want a good office chair for not too much money? Basic with mice: gross motions (like across the screen) with the heel of your hand off the desk surface, but when it gets to fine motions (photoshop, whatever), put the heel of your hand down and just use your fingertips. I personally find trackpads more comfortable, but off to the side, where a mouse would be. Keyboards: at least try a negative tilt (back lower than front). NB: I went through all sorts of keyboards and mice (and desks and monitors and chairs) some years ago as I was starting to get numb fingertips, which is one sign of RSI.
