Electrical in code?

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.

electric motors

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.

Electric didgeridoo

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

Electricity for the challenged

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.

Wireless Electricity!

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..

Electric Gramophone?

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 :) .

Electricity over IP

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."
