Recycling is great. We’ve seen a pretty hard push in that direction recently. We like the fact that our modifying of hardware is generally saving it from the dump. Keep in mind, that just using old hardware can be advantageous too. We don’t always need the new shiny thing, maybe we’re fine with what we’ve got. That is exactly what lastyearsmodel.org is about. You can join their facebook group and even get stickers for your old devices.
WEEE Man is an art display that has been roving around England. No, he doesn’t walk or talk. He is here to remind us of how wasteful we can be. Hackers rejoice, we’re part of the solution. It also doesn’t hurt that he is Seven Meters tall and over three tons. WEEE Man looks awesome, but are we the only ones that spotted stuff and thought “ooh, I could have used that for a cool project.”?

If you’ve never heard about electronic paper, crawl out from under that rock and read up on the Sony Reader and the Amazon Kindle. E-paper is a flexible display made of color-changing beads that mimic ink-on-paper for easy daylight reading. The revolutionary thing about e-paper is that after it’s set, it stays that way without additional power.
This sounds great in theory, but Esquire’s cover is the first time everybody can afford to hack an e-paper display. We took the cover into the Hack a Day lab to document, test, and hack. In the end, we recycled it into something useful that anyone can build. We’ve got all the details on how the display works and what it takes to use it in your own projects. Read about our e-paper clock hack below. Continue reading “How-to: Make an e-paper clock from Esquire magazine”
While not very technical, [3eff_Jeff] posted an interesting modification to an empty air canister that makes it refillable. He was tired of drilling holes in the ozone, so he carefully drilled a hole into the top of the can instead. In the name of caution, he made sure the can was completely empty first by tying the trigger down with a rubber band. After waiting a while he carefully drilled the hole using an oil lubricant, and then epoxied in a Schrader valve from a leftover bike tire tube.
Due to compression of the air as it is pumped into the can, it becomes quite warm. He found that if the can is allowed to cool to room temperature, the air would become very cold once leaving the canister, which would cause condensation problems. So he uses it right after filling, and then empties it out when not in use.
We do not recommend anyone trying this, but it is a unique way to make a commonly used disposable resource in the computer field reusable. If we can use something more than once, we’re definitely for it. That’s why we support recycling components that would otherwise make their way to the landfill.
If you’re anything like us, you have a closet full of old electronics, some broken, some obsolete. You can stop using those as paperweights with the help of this guide that shows you how to recycle and reuse PCB components.
The first step of the process is finding electronics you don’t mind taking apart. Next place the PCB you’ll be stripping in a vice, with the components facing away from you and the solder side facing towards you. Grip the component you want with a pair of pliers, and apply a hot soldering iron to the solder that is holding the component. The solder will melt and allow you to safely and cleanly remove the component.
This process can be applied to virtually any component on an PCB, and the author of the guide, [Patented], got a lot of components this way, including resistors, capacitors, switches, audio jacks, and much more. Don’t forget to toss any free-floating metal or plastic parts in the recycle bin when you’re done. You can feel good about the fact that nothing was wasted, you found parts for your next project, and you cleared out some space.
Back in November we asked what you would do with an old unused laptop. If you have an old laptop that’s not doing much more than gathering dust, chances are you could put it to better use. You could sell it, but you probably wouldn’t get too much for it. Donating or recycling can also get it out your hair, but if you’d like to try something different, read on for some ideas.
