Hack a Day
This auto-flute does it with steam. Well, electricity gets its piece of the action too as the tone holes are opened and closed using a set of solenoids. We’re at a loss on how the sound is actually produced. We would think that a penny whistle has been used here, except if that were the [...]

Chaos Communication Congress 28th (28C3) 2011 Abstract: This talk, consisting of five distinct parts, is intended to show the audience how to get electricity without needing a grid connection. It will give information on Which energy sources to use What to power with them What equipment to get How to wire it up And some wishful thinking Participants should be able to assemble their own small-scale energy-generating systems after listening. Renewable energy isn't for wealthy investors only. You can have it, too. In this talk we'll show you how to power your own stuff from the sun, wind and other sources of energy. The talk is divided into 5 different parts: A really short introduction into the available power sources like sun, wind etc. We'll show some pipe-dreams where more hacking is needed to make it work like salt-gradient energy or damming the mediterranean sea. We'll show you how much power you can expect from which source. We'll also show you what affects power output for various technologies (example: Sun needs to be shining for solar power. We'll show you how much sunshine you can expect at your place.) As a follow-up to part 2 we'll show you the amount of power various things need. You can do the math yourself afterwards to see what you can power from your balcony. Building the system, the easy and fully-legal way: Build your own independent grid with optional storage. We'll show what you need for a small-scale solar system independent of the power network. Works well for caravans, camping, gardens and allotments. There will be real solar panels on stage. You will see schematics, parts lists and instructions. We'll give some hints where to aquire the necessary stuff without paying too much. The difficult way: Put your own power into the public grid. We'll show you what you need to do this. This can either make your purse fill up automatically (big installations earning feed-in tariffs) or it can (in theory) make your electricity meter go backwards - but that's not actually allowed. Once the electrical company recognizes what you are doing (and German law requires you to tell them) unfortunately they will install a digial meter. Digital meters will not count backwards like the Ferraris counters do now... The speakers have built and are operating various small-scale power systems and come from an engineering and commercial background.

Hack a Day
[Janne Mäntyharju] wanted to get an idea as to how much electricity he consumed in his new home, mainly to see if using his fireplace for additional heat had any effect on his bill. Luckily his power meter was mounted in the utility room of his house, making it easy to keep tabs on his [...]

You probably know that if you spin a motor (mechanically) it generates electricity on what would normally be the inputs. This can be a problem when you shut off a spinning motor and is the reason that protection diodes are built into motor driver circuits. But [Dino] isn’t interested in driving a motor, he wanted [...]

For years, [Rasmus] has left his computer connected directly to the mains power so that he can turn it on via Wake on Lan. While powered down, it would still continuously consume about 6W of electricity, but now that he didn’t need it to be on standby so often, he wanted to make it more [...]

Here’s a project that’s hard to categorize. It generates electricity by burning wood. The diamond-plate wrapped column to the right is a magazine that stores the wood, which is gravity fed as pieces below are consumed. The heat is used to drive a power turbine which is responsible for generating the electricity. This begs the [...]

[Niklas Roy] is rolling out some water-powered music for Berlin’s Museum night. It seems that this water-wheel is attached to the side of the Museum. It’s got a stream flowing past it and the wheel is constantly turning. The thing is, that work isn’t being used for anything. Now we’ve already seen [Niklas] making electricity [...]

If you have had it with persistent weeds that seem to come back no matter what you do, here is an ‘environmentally friendly’ way to kill them off permanently. By using a probe charged with 2400 Volts, [Jack] shows how you can conduct the electricity through the plant and all the way down into its [...]

Hackaday reader [grenadier] wrote in to share a series of tutorials he is working on, where he discusses the basics of electricity and electronics. The first lesson titled, What is Electricity?” has been wrapped up, and is available for free on his site. For any of our regular readers, the lesson will seem pretty basic [...]

[Paul] was pretty sure that he and his family used a lot of electricity throughout the day. Admittedly, he enjoys his creature comforts, but was wiling to try living a little greener. The problem was, he had no idea how much electricity he was using at a given time. While some power companies offer devices [...]

Yep, these cereal boxes light up. They’re using a new branded-technology called eCoupling that provides electricity via induction, which means the shelves have a coil with AC power running through it. The “printed coils” on the boxes allow inventory control and data exchange presumably thanks to a low-power microcontroller. But in the video after the [...]

As he does every year, [Joe Grand] gave a talk explaining the development process for Defcon 18 badges. We looked in on these when details started trickling out back in July. They feature a neat bit of tech in the form of an LCD that acts much like ePaper. It doesn’t take any electricity to [...]

[Niklas Roy] wanted to create electricity from moving water so he came up with this hyrdopower generator. It is part of his grand scheme to rent out small personal fountains made from buckets. They need electricity to run so he hooked up the generator to the water jet of a public fountain. It should be [...]

Many exercise machines generate electricity as you pedal or climb in order to run the on-board electronics. Unfortunately if you stop or even slow down too much the juice will die and your exercise program will reset. Wanting to improve on this gotcha, [Mike] cracked open his exercise bike and added some super capacitors. On [...]
