How to Build a DIY Portable Solar Charging System! - 2011-05-12 05:44:12-04

5 years ago, it was a lot harder to build your own solar-charging systems but now there are so much more resources plus price of solar systems have dropped quite a bit. If you own a home and you have some space in your backyard (or roof) for solar panels, there’s absolutely no reason why you aren’t powering some of your home electronics via the power of the sun (unless you live in Alaska and it’s no-sun season). Here’s a great example of a DIY portable solar charging system built completely from scratch with most parts bought on eBay, a portable solar charging system with wheels and you can plug-in anything. You’ve probably found this Instructable to gather ideas about making a portable solar power supply yourself. I’ve always been interested in electronics with this project being my latest idea to come wandering out of my head, why not make a portable box on wheels, that I can plug basically anything into, thats powered by the sun? So therefore I thought I’d share this Instructable with the rest of the world. For starters who don’t know anything about solar circuits, you might also want to check out this Solar Power … Continue reading →

How to Make DIY Arduino Ethernet CandyGrabber! - 2011-05-12 07:20:40-04

I’ve spent a lot of time at my previous company Comfile building ethernet-enabled devices, which is one of my favorite projects of all time (you can see some of my previous projects after this article at the bottom). Anyways, Odvratno Zgodan has made a really cool device, it’s an ethernet-enabled DIY Arduino CandyGrabber, which works off Adobe AIR, PHP socket, Red5 server to allow anyone to control his CandyGrabber of the internet. You can try it out yourself here at pimedius.com. This could be very helpful for those of you who are trying to build ethernet-enable Arduino devices, you can refer to the DIY page over at Instructables. So how should it work? The idea is that there is a Flash AIR app on my home computer that when a remote client connects to it starts the video broadcast. The communication between the client and the AIR app would be through a PHP socket because it can instantly push messages from one to the other. The socket will handle all the clients and the queuing. The Red5 server is used to handle the video broadcast, stream the video and send the arduino commands from the client that is first in … Continue reading →

How to Make a DIY Amplifier for Less Than $20! - 2011-05-12 10:33:10-04

Dino Segovis from HackAWeek.com, has put an excellent tutorial on how to build your own DIY Amplifier for less than $20 with LM386 chip and parts bought from RadioShack. As you can see in the video below, this 1/2 watt DIY amplifier is pretty powerful little amp, all encased in an altoids tin. This small amp even has a guitar jack and ability to distort sounds, pretty darn impressive for a small circuit. I think this is a great, simple circuit for those of you who want to build your amps. In fact, I will have to try making this very amplifier soon. via hackaday This post How to Make a DIY Amplifier for Less Than $20! was originally from zedomax.com Audio, Circuits, DIY, diy amplifier, Featured, Featured DIYs, Featured Gadgets, Featured Hacks, Gadgets, Hack, how-to, HOWTO, make, Projects, technology

How to Make DIY Credit Card Earbud Holder! - 2011-05-12 18:53:11-04

I own a ton of earbuds and I usually store them in earbud cases that I got with my nicer earbuds but for those of you who don’t have an earbud case, I highly suggest you to make a DIY credit card earbud holder such as shown above to protect your investment. The #1 reason why earbuds fail is because users don’t protect them and put them all tangled in their pockets and whatnot. When earbuds tangle, there’s more likely chance you are going to break them in places. I’ve personally broken many earbuds but after I started using earbud cases, that number went down to zero. via unplggd This post How to Make DIY Credit Card Earbud Holder! was originally from zedomax.com Audio, credit card, DIY, diy earbud holder, Earphones, Earth, Featured, Featured DIYs, Featured Hacks, Gadgets, Hack, how-to, HOWTO, make, Projects, re-make, Re-use, Recycle, technology

Top Five Coolest iPhone 4 Cases - 2011-05-12 23:38:37-04

When I look at all the gadgets and tech stuff that we have featured over the years, the iPhone still stands out as being one of the most iconic and desirable devices around. Therefore, with the iPhone 4 in its twilight days and the next version waiting in the wings, I thought it would be a nice send off to take a look at some of the coolest cases around for the iPhone 4. These cases range from those that have been designed to protect the device from scratches, marks and even small dents that can easily happen in a busy office or work place. The cases selected on this occasion have been chosen not for the cost or looks. These are the cases that have been the bestsellers in the market and therefore should be considered as being some of the best on the market. The Trident Case Aegis Series There are many points to the Trident Case Aegis Series, it has been designed primarily to protect the device from drops and knock, but at the same time, this case has turned out to be a real cool looking case that has be made up of different layers for … Continue reading →

Boeing 747-8 Brake Performance! - 2011-05-13 07:20:40-04

Here’s a really interesting story of the Boeing 747-8 brake testing and performance, which utilizes 100% worn-out brakes on a 975,000-pound airplane. (That’s almost a million pounds!) In April, the Boeing Test & Evaluation team brought the 747-8 Freighter to a long runway in California to simulate the ultimate rejected takeoff (RTO). Crews loaded the airplane above its maximum takeoff weight of 975,000 pounds (443,181 kilograms) and installed a set of 100% worn-out brakes. The kinetic energy from the moving airplane was transferred to the brakes in the form of tremendous heat, estimated to be more than 2,500 degrees Fahrenheit or 1,400 degrees Celsius. As expected, the brakes glowed a bright orange as smoke poured out. The result? Boeing 747-8 was able to stop within their expected mark by 700 feet.
