Picture of Bicycle headlight shelf lamp

Hi everybody , i'm from italy and i love bikes. I ride 'em , fix 'em and create stange object with old parts.

You can find some of them here: http://www.2you.it/ilmecca/Page7.html
                                                            (it's in italian but the photos are self explanatory)

or here: http://www.facebook.com/IlmeccaProduzioni

The goal of this project is create a shelf lamp that is simple to build , cheap and effective.

While encouraging people to build things , i have remember you to always put safety first when using tools and managing electrical devices , if in doubt ask for help but don'risk.

This is my first instructable, so i hope you'll enjoy , and remember to vote for the contest!


Now let's see what we need.

Step 1: Things you need

You'll need:

- an old brake caliper (a rear one is better as it has a shorter thread, if you find a front you'll need an M6 x 25mm bolt)

- an old bicycle metal headlight (the larger , the better)

- a spring (i used one from a saddle, lenght is unimportant as we'll cut it)

- an M6 Nyloc nut and washers

- a tin can or jar cap or metal sheet (not in picture)

- a GU10 led bulb (a 3w or 4w is fine)

- a GU10 socket with wires

- a power cord with a switch and plug (choose the right one for your country)

- a short piece of heat-shrink tubing (not in picture) or pvc electrical tape

- a zip tie (not in picture)

Essential tools:

- 8 , 9 , 10 and 11 mm open spanners (you'll probably need only the 9 and 10)

- pliers

- flat screwdriver

- pincers (to cut the spring)

- ruler or vernier caliper

- electrician scissors


Useful tools (will make your life easier):

- Bench vise

- Half round hand file

- Disc grinder or dremel with cutting and sanding tool

- soldering iron and solder

Nice use of brake calipers as a spring clamp. I will use idea this someday. Thank you.

What a great lamp. I'm in the process of building a desk lamp from an old bicycle headlight myself. So during my research I came across your instructable and just posted it in my newest collection: upcycled desk lamps.

Thanks to all for the kind words.

Vincent7520 , you need a dynamo , but you'll have to pedal a lot to produce enough electricity.
Nice idea !
Great instructable : everythings (or almost) comes from a bicycle : this is very neat.

But how do I get to pedal for producing electricity ?… ;)))

This is an excellent idea and I love the design. However, as this is using a metal bike lamp, the metalwork really should be earthed and a three pin plug used. Alternatively, use a 12v LED spot with a 12v mains adaptor.

Yes , to be completely rule compliant, the earth cable is a good idea, but if you do a good job in isolating the connections and stay away from water, the 2 pin plug is generally enough.
I don't like external adaptors , as they use (a little) energy when not used.

Good point... and they cost more!
I've always wondered, why the white cable, and the ground terminate in the panel in the same place. Redundancy?
Good question. The neutral (white in your case) is joined to earth at the local substation. Otherwise the power cables (live and earth) could be at any voltage wrt earth, especially if they were hit by lightning or just static. However, due to the current traveling through the neutral wire from the substation to to the house and the fact that the neutrel wire has resistance, this will create a voltage on the neutral wire in your house. Therefore, the neutral is bonded into your house earth which is earthed locally, via an earthing stake or metal water pipes.
I once lived in a house where the neutrel was joined to the metal mains water pipes as earth. This was fine until the mains water.pipes were replaced with plastic pipes by the water board and I started to get tingling type shocks off the water taps on finger cuts. When I put a meter to the taps, they had a voltage of about 40v ac to earth, not enough to kill but enough to cause the tingle. Re-earthing it to a proper earth cured the problem.

I came across a similar situation to wobbler. The earth connection to the earth electrode in my son's house had been broken. My son started to get a tingle shock every time he touched the kitchen sink which was bonded to the electrical earth of the house. It was only a static charge that built up in the earthing system with no where to go except through somebody who touched the sink, but if a faulty piece of electrical equipment had been plugged into the mains system of the house, it would have simply been leathal! Finding and fixing the main earth cable was of course the cure.

Now, my point is, if you are not totally sure what wobbler and I are talking about, then I would suggest you do not know enough about mains electricity systems to make this lamp with mains bulbs. Instead, as has already been suggested, use a mains adapter power supply to take care of the mains side safely and use low voltage LEDs in the lamp.

I think the concept of the cycle lamp is an excellent idea, and makes a really good looking item, but my advice is don't risk killing somebody. Every uear 20 people in the UK are electrocuted by their bedside lamps or radios, and those are the ones that are made by the manufacturers!
