Fresh hacks every day
Backyard parties are going to rock over at [Effin_dead_again's] house. That's because he just finished building this outdoor stereo. It carries its own power supply so you can take it on the road with you, and we don't think you'll have trouble hearing it with the 240 Watt amplifier hidden inside. He shared the equipment details in his Reddit conversation. A 12V lawn mower battery sits in the … [Read more...]
You're not going to be doing any flip-tricks with this board, but it'll let you get around without getting sweaty. The ZBoard is a motorized skateboard which is in the pre-order stages thanks to a successful Kickstarter campaign. It'll set you back $500 now or $600 later. With that kind of budget wouldn't it be fun to build your own? This base model can go about five miles or five hours between … [Read more...]
Many of you will remember [Mikey Sklar] from the multitude of times he's been on hackaday. What you may not have noticed is that he is an ubergeek, living off the grid. He has Solar PV battery bank, three electric vehicles, a shipping container loaded with battery powered tools and a small army of iRobot Roomba's for cleaning. Getting the maximum lifetime out of a battery by removing sulfation is … [Read more...]

On sunny days it will top off the car battery, letting him use his stereo in the middle of nowhere without needing to keep the engine running. Instead of buying a ready-made solution he chose to design and build his own charging circuitry. The charger uses an Arduino, … [Read more...]
[Adr990] wants to make sure his Game Boy game saves aren't lost to aging batteries. They're stored in SRAM with a small coin cell inside the cartridge to keep the memory energized when the game is not being played. But if you pull out the battery in order to replace it the data will be lost in the process. It turns out that you can hot-swap the battery without too much effort. As shown in the … [Read more...]
Looks like ice-cube trays are once again proving their versatility as this one is serving as the vessel for a home made lead-acid battery. With a collection of uniformly sized non-conductive containers, it makes the perfect base for a set of small cells. This project is the culmination of a Hackerspace class about batteries, and was put together to turn theoretical knowledge into a hands-on … [Read more...]
When [Soo-Hyun]'s friend had an Apple Macbook Pro battery that began to swell, his friend did the reasonable thing and donated it to be used in a robot. Now [Soo-Hyun]'s kiwi drive robot is powered by a gigantic LiPo battery, giving it a huge range and a very fast top speed. The defunct laptop battery that formerly powered a 15" macbook pro is three battery packs of two cells in parallel, … [Read more...]
