Hi, I came up with a new way of doing lighting and would like to post it as an Instructable. There's only a slight modification of existing components and standard electrical hardware is used, but I'm concerned I may be called out for possible electrical code violations. Are these checked by the Instructables crew or every project is treated with a warning that anyone using each project needs to be aware of electrical code issues? Thanks.

I was going to fry some potatoes, but my electrical ring failed with arcing, smoke, noise & sparks... I'm not happy. I've got the ring to replace, a pan, and I've got sooty-oil to clean up. And no fried-food. And the place stinks of burned-oil. And I've lost / spoiled half a bottle of fresh oil. Oh, and I'll have to pay for the electricity that did this too. And I need some 30A fuse wire.

Is there any components that set the minimum energy to pass through? When the energy is lower than the fix amount , no energy will be passing through. I'm trying to make a project. I'll put a dynamo on my bicycle, and it will be connected to 3 LEDs. When I cycle in low speed, only one LED will light up. When I increase my speed to certain level, 2 LEDs will light up and if it passes a certain speed all LED will light up. Any idea?

Ok i want to build an electric hybrid system my first question is ac or dc power. i want to build a paralleled drive system. that uses the stock motor to drive on the highway with maybe a little help from the electric motors. here are my thoughts start with a f250 powerstroke diesel crew cab truck, install a divorced t case and new drive shaft, hook the electric motor to the t case front axle output. the goal is to use the space by the tool boxes to fit the batteries and later update the alternator. the goal here is a hybrid that can still haul what a normal truck can but run purely on electricity when in town

I am working on a motor bike that i had originally decided to go gas with but the motor dosent work anymore so i changed my mind and went electric. i was wondering if i would still need a jackshaft with an electric motor. it is a 24 volt motor out of a powerchair. i don't know specifics on tourque and hp, but it's pretty powerfull, and turns quite a few rpms. any help would be appreciated. thanks.

Hello, I have an electric bass .. I broke the two wires that is connected to the battery connector a couple of months ago.. I had it professionally soldered. All of a sudden, today, it started to static every time I played a string. I switched amps to make sure isn't wasn't any of amps. But it started to static on every one.. Could it be that the battery is going dead??? Please help!!!!! I have a gig this weekend!!

I am considering motorizing my bike for my work commute. However I don't have enough knowledge about motor output as in torque / rpms to be able to determine what kind of characteristic I should be looking for. For many of the electric motors I am finding online, it doesn't really say the torque output. Is there a spec such as watts that I can judge a motor by? What specs should I be looking for in a motor that can assist in moving my weight. Or an links to good knowledge sites would be great too. Thanks.

So a few years back, my teacher had this toy chick, that had two contacts on the bottom. When you touched both, it chirped. Whn you touched one, and you touched a friend who touched the other, it chirped. So if electricity can run through you like that, why cant the same thing work with a battery and something that takes that battery? (leave the +side in, touching the - side, and then touching the contact for the - side)

Bored with traditional digeridoos, Kyle Evans made this electronically modified, Bluetooth PVC didgeridoo. The Bluetooth allows him to not be tethered to a computer and the controls on the sides allow him to modify the sounds in the middle of a performance. It takes a lot of breath to power the 4.5 foot didgeridoo, but with a feedback feature he can keep the sound going and catch a breath, which is a little easier than the typical circular breathing. This took 3 months for him to build at a cost of $300. You can hear a sample of it in action here. You Built What?! The Electronic Didgeridoo

I want to convert my old gas mower to an electric mower. 12v batteries are easy enough, and there is plenty of info re solar charging systems. I'm stuck on sourcing the motor. I was wondering if a car starter motor would be sufficient for running a lawnmower? It's a 12v motor, has enough oomph to turn over up to 12 cylinders of american steel, and there are plenty of 'em out there in junkyards waiting to be recycled. Sounds good on paper. Anyone have any insight into why this is or ain't a good idea? Thx- Rev. Bucky

I have a US plug AC/DC power adapter and need to get a European version. The specks on the adapter are input: 120VAC 60Hz 24 W and the output: 10 VDC 1400mA. I really don't have a clue as to what all these numbers mean but understand at a bare minimum I need something with a 10 VDC output. I've looked around at some shops and can find adapters that say 9v 1000mA and others that are 12v 1500mA. Do I need to get the exact voltage (I presume the v stands for volts)? What about the amperes ( I believe that mA is some increment of amperage)? Can I fudge the numbers a bit to save money and time instead of trying to get the exact configuration of the original adapter? Thanks for any help in clarifying this for me.

I'm playing around with the idea of wireless power. It should be easily do-able over a short distance- my plan is to be able to charge something like my cellphone through induction, by placing it on a powered surface.. But- I don't know a whole lot about induction, so I was hoping someone could help me out a bit. Here is my setup: I'm using coils from old 5 1/2" floppy drives. I used them once before in a BEAM bot pendulum.. I set one coil on top of another. So far, by pulsing 9v DC through the coil, It sparks a little (because its shorting I assume) and the multimeter in the adjacent coil gives me a small spike of voltage, but quickly returns to zero. Zapping repeatedly gives me at best 2.5v, which is totally acceptable, if only it was sustainable. I've tried using AC 9v.. but I didn't seem to work either. I also tried some different on/off cycles with a BS2.. no luck. Any info would be quite appreciated..

I've just had an idea for making an mp3 player disguised as an old gramophone, to be used as a set piece/source of music for busking. Problem is, I can't figure out how to pull off some of the details of making it... Heres the idea as it stands: Have an old gramophone that appears to be playing music from a record, but is actually playing music from an Mp3 player. I figure you could interrupt the signal from the needle to the amplifier without to much trouble, as you'd still need the needle there to make it move along the record as it 'plays'. It also shouldn't be too hard to hide a speaker in the trumpet or even embed it into the side of the gramophone. In an ideal world, it would also be great to have some general controls on the back, to select play lists and the like, and that's probably achievable my attaching it to a standard mp3 player. The tricky bit is that I want to get it to play when the needle is placed on the record, and stop when the record finishes, ultimately with a digital replica of the scratch sound that you get at the end of an old record. Does anyone have any ideas on how to go about this part? because I'm absolutely stumped... is it possible that the answer lies somewhere in using the movement of the needle-arm to complete a circuit while in certain positions? Any thoughts, help, ideas or suggestions would be appreciated :) .

A friend of my fathers had a dry cell powered device with two metal handles you gripped while the operator slid a rod in a coil to increase voltage. the idea was to hang on till you couldn't. These drunks would hold on till the thing made their wrist muscles contract their hands into claws. How would you build this thing? Thanks, Zappenfusen

I would like to make the LEDs in the pre-wired controller in the first picture shown blink to music using the formula in the second. I was thinking that I would need to leave the +/- coming out of the controller on different power than the LED strips this way you have constant power to the controller and therefore the remote to control the colors. Anyone know how I can incorporate this?

This is not really a new concept (first published in 2002), but one to mull over :-) Electricity over IP (EoIP, pronounced "yoyp") is a proposed scheme for delivering electric power via IP (Internet protocol). EoIP was developed to eliminate the unnecessary redundancy inherent in maintaining separate distribution networks for electricity and the Internet. The technology could be especially beneficial in remote areas with Internet kiosks but without electricity.The architecture for delivering EoIP is known as MPLampS (Mostly Pointless Lamp Switching). Electricity is digitized and encapsulated in discrete packets. According to the IETF's marketing segment, "MPLampS has the potential to dramatically lower the price, ease the distribution and usage, and improve the manageability of delivering electricity." Electricity over IPThe IETF Network Working Group described EoIP in RFC 3251, published on April 1, 2002. April 1 is also sometimes known as "April Fools' Day."

Sometimes a topic is just as mysterious after you read the guide.My guide is different.In all honesty, this guide is a bit simplistic, but it does have a nice description of why there's no point to worrying about surges when electronic devices are powered up.
