Being “Energy Efficient” at home isn’t just for granola-eating techies or Elon Musk. It’s the best way to reduce the price of your utility bill each month while also reducing your environmental impact on daily basis. The US Environmental Protection Agency (EPA) defines energy efficiency as “delivering the same (or more) services while using…
The DC One unit is an interlocking, programmable, single-channel DC power supply that can be powered by either a battery or an AC/DC adapter. The DC One unit is an ideal power source for developer or hobbyist projects such as Arduino or Raspberry Pi powered devices. The DC One is designed to provide highly efficient operation, even with higher load…
Build Something That Matters Last year The Hackaday Prize began a movement, this year we’re solving problems that matter to everyone. The creative energy and years of experience found in our huge community of Hackers, Designers, and Engineers is waiting to be unleashed. Let’s use that potential and move humanity forward. This doesn’t mean one…
Very interesting solution to have for only $35 a full power station, really usefull when testing your self made boards. And with interesting features, as you can read here: The PowerG gives you the ability to control power like the expensive bench top power supplies. It provides two outputs: 5V-12V and 1V-3.3V. You have a…
PiJuice project has been already 500% funded on Kickstarter, and still one week to gather funds! What is PiJuice? As one of the smallest systems around there’s so many amazing things you could do with the Raspberry Pi if it was self-powered and portable. With PiJuice we want to provide not only the best portable…
ArduRF is is a wireless electronics development platform closely based on Arduino hardware that wants to make Wireless Links easier keeping full Arduino Compatibility with Long Range AES-128 Encrypted Radio Link, all this being Battery Powered or operating from a Solar panel for independence. Let’s see if the explanations of the founder, can help you understand why is…
Today we’ll show you how to feed a whole Arduino system from a battery, optimizing energy consumption to ensure that the batteries would provide power to the complete system for few years. Perhaps, the only shortcoming of Arduino is that there aren’t any sophisticated tools in case you want to use a battery power supply….
This recently funded project for an open source mobile green energy generator (a wind turbine) that you can carry with you! It’s a 3D printed, foldable wind turbine boosting 300W of power and it’s also open source! once we develop AirEnergy3D we will upload all technical data for everyone to use free of charge. All…
We recently presented our Open Source Solar Lawn Mower, project to Boca Bearings Innovation Competition and it has been selected and you can now vote for it! This lawn mower uses only energy from the sun and does not require any external power source, that can operate in areas not covered by the electricity service. Is very simple…
This project really hit the news earlier on this month: looks like after completing successfully its kickstarter campaign the guys are on track to change the world of solar providing a product that could be used by anyone to make DIY solar panels. – See a good coverage of he project here: http://livefreelivenatural.com/backyard-solar-factory/#sthash.pgMraFdt.sThNyFvF.dpuf A Solar Pocket Factory…
This Solarpad solar phone charger project is pretty amazing and it’s open source! A fully charged Power Core will recharge a dead iPhone from 0% to 100% in 3 hours even after being unused for a month! Our competitors may have a power level indicator, but for this size solar charger, power level indicators are inaccurate…
University of Washington created a wireless communication system that allows devices to interact by harvesting power from the environment.. See the complete paper here: http://www.theengineer.co.uk/Journals/2013/08/14/u/g/g/comm153-liu.pdf Using so-called ambient backscatter, these devices can reportedly interact with users and communicate with each other without using batteries because they exchange information by reflecting or absorbing pre-existing radio signals from TV…
