The Graffiti Research Lab Vienna tool development archive is finally being brought to light. Here we present the Powerthief, an old piece of technology that we didn't come up with, but is worth reviving. By now they are mostly made redundant in every day life, and also illegal in most of central Europe. However, there are still useful applications for it in our environment today, especially if you're in need of a power-plug where there is usually none available.

The basic idea is pretty simple: in a lot of today's urban environments you can find a regular light bulb reasonably close-by. In Vienna, where this was executed, you can find one above almost every doorstep. The technology is even simpler - take the screw-cap of a regular light bulb and instead of connecting it to filaments it's being connected to a power socket.

To see how we made it and use it, we have a video we presented at the 2 year anniversary of the lovely gallery INOPERAbLE:



This project deals with electricity. Make sure not to blow yourself up!

You will need:

  • A light bulb
  • Electric cabling
  • Plastic tubing to cover the cabling
  • Power socket
  • Epoxy
  • Something to cut the tubing
  • Soldering iron and solder

Step 1: Putting it together

There isn't all that much to do. The steps have been captured (and played faster) on the video linked on the intro page. Remember that this project is dangerous and the use possibly illegal if you are in Europe. Improvise. In the video we used hot glue, but epoxy works better.

  • Break the light bulb and get rid of excess glass/other material
  • Solder the cables onto the connections (bottom and side) of the screw cap (there's no + / - since it's AC, so connect it how you want)
  • Make the casing from the tubing
  • Put the screw cap and the casing together with the epoxy
  • Connect the cables to the powerplug and put it on with epoxy
  • Test with care in a safe environment

This device can be found at Home Depot for $2.50. You can plug a light into it and a power cord at the same time. If you replaced the incandescent bulb with a compact fluorescent bulb and made sure the device you plugged in used less than the difference in wattages then the same amount of light would be put out and you wouldn't actually be stealing the power. And you wouldn't run the risk of over loading the supply wires.

This "Plug In Socket Adapter, also from Aubuchon Hardware, can be used to convert the above "Plug Base Attachment" back into a socket, so that you could change a bulb by just yanking it! No more screwing on a stepladder or standing on a chair!* Much safer.

Also available is one that converts the lamp socket into one receptacle. Here in the US AC receptacle are polarized, to insure that the neutral conductor, isn't switched with the line conductor, and of course the safety ground isn't carried through with these adatoptors. In the event you homebrew one of these things make sure, the neutral remains the neutral.

wow THANKS man
unjust in reply to nolte919Mar 12, 2009. 11:45 AM
those devices are illegal in europe. (as noted several places)
pedxing says: Mar 12, 2009. 7:13 PM
The polarity does matter in AC, for safety purposes. The "Hot" wire (black or red) connects to the centre, and the "Neutral" (white) goes to the side.
_soapy_ in reply to pedxingMar 19, 2009. 12:42 PM
In general, what you say is true. However, you have no way of knowing that the light circuit is correctly wired. And that standard may not apply in other countries. In the UK, the old standard was that red was live, black was neutral and earth was green, yellow or striped green/yellow. The newer standard is that live is brown, blue is neutral, and earth is bare, or green/yellow striped. However, the biggest issue with this hack is how to turn the light on?
bo88y in reply to _soapy_Apr 19, 2010. 3:13 AM
A very basic circuit tester can tell you which is hot and which neutral.
Rimwulf in reply to _soapy_Mar 20, 2009. 11:24 PM
why does everything has to be complicated in the UK? the only standards I can remember right now is that we stopped us aluminum wires in housing.
stormende says: Jan 16, 2010. 9:49 AM
Hahaha it sux. Had to watch the whole video to notice that... We have it here in México! and they are legal so how many of them do you need?

:D

 amps.....
in the uk your household lighting should be rated at 6 amps.
if its commercial it may be more like 10 amps,
as to france, they wire lighting radials on a 16 amp breaker.
but both the UK and france have RCD protecting the whole fuse board rated at 30mA.... this is a rad idea but you gotta have a rough idea what your plugging into, and in the worse case if you pull to many amps you'll trip the RCD, if it doesn't have one you'll trip the breaker....
if however the owner has an oldschool fuse board with re-wirable fuses and has either used the wrong rating of fuse cable or used some tin foil from an old kit-kat wrapper, you'll probably start a fire.
this is still a rad idea and i need one in my life.
peace

they sell these every in the US.... lol
MadMoose says: Mar 28, 2009. 9:39 AM
It's called a "plug body". You screw it in to a light socket. Been around since about 1910.
abadfart in reply to MadMooseJul 16, 2009. 1:52 PM
ya i got like a million and a half around my house
lil jon168 says: May 21, 2009. 3:23 PM
do you just screw that into the light socket?
firehazardjewelry says: Apr 15, 2009. 12:53 AM
well, this kind of premade plugs are not available in europe at all. i found them here in the us the first time ever... so, if i see the pictres right, it is done in europe...lol... and there they do not know that system at all... because safety..you know...smile
Love_Not_Found says: Mar 26, 2009. 9:41 PM
not only do they use differant power plug but they use a differant voltage the screw in outlets woudnt work there and would probily short out anything you even tried plugging into it
phillipnolan says: Mar 26, 2009. 8:11 PM
Guess you never ran across these nice pre-made units. Less expensive and much less labor intensive.

LarrySDonald says: Mar 12, 2009. 8:57 AM
I really don't see where this would be more of a danger then plugging something into an unknown standard outlet. They rarely come with a little sticker saying "Please don't draw above 300W from me". Light sockets are no different - just another form of connector. Both should, at least in theory, be fused to whatever they are capable of providing. I'm not sure if lightbulb connectors (as opposed to sockets) have a vastly higher rate of not being properly spec:ed or something, but otherwise it'd be the same as an outlet - they promise nothing, including not promising you can safely hook up 100kW of electronics to it.
static in reply to LarrySDonaldMar 25, 2009. 3:21 AM
In the US lighting fixtures are often on the same 15 amp lighting circuit as the receptacles are, typically speaking. However that's not to say any lighting fixture can safely conduct 15 Amps. Lighting fixtures often do have a warning as to not use lamps over a certain wattage, but that's more about the heat produced by the lamps, than it is about the current handling capabilities of the fixture. In not knowing what other load is one the circuit as the lighting fixture, your use the powerthief on there's a chance your use of it may trip a breaker.
unjust in reply to LarrySDonaldMar 12, 2009. 11:47 AM
because you may be tying into a dimming or building control system that won't be outputting the standard wall outlet power, or the circuit may be sized for x # of 30 watt lamps, so you changing one lamp for a 400w demand could cause issues. or the wiring in the fixture could be only rated to 50 watts, so running 100w through could start a fire.
The Lightning Stalker in reply to unjustMar 20, 2009. 9:01 PM
The wattage ratings are based on heating issues with incandescent light bulbs more than for electrical reasons. The higher the wattage, the more heat produced, and enough heat will melt or burn the fixture. Just attaching wires will not produce this type of heating. In this case it becomes an issue of the current carrying capacity of the conductors in the circuit. This depends on the cross sectional area and metal the conductors are made from.

Nope, that breath you just took just cost you $1, now pay up
Sandisk1duo in reply to mondaymonkeyMar 19, 2009. 5:49 PM
*rolls teh eyes* there's no tax on air!
jaredsalzano in reply to Sandisk1duoMay 8, 2009. 10:57 AM
In some countries, yes.
Yerboogieman in reply to Sandisk1duoMar 26, 2009. 7:41 PM
It's included in all the taxes on everything, just, it isn't said anywhere it is taxed.
greiss122 in reply to Sandisk1duoMar 19, 2009. 2:46 PM
Nope, trees make it for a cost: us not killing them. That didn't make much sence.
Sandisk1duo in reply to greiss122Mar 19, 2009. 4:22 PM
you can take as much air as you like, no one will bother to stop you
greiss122 in reply to Sandisk1duoMar 21, 2009. 7:33 AM
True, except maybe the air police
psychlones in reply to Sandisk1duoMar 20, 2009. 7:24 AM
Maybe where you live but even as we "speak" in the New York Metro area there are politicians looking for ways to circumvent the ACLU in order to require subcutaneous implantation of micro-valves that would cut off or restrict the air flow should you refuse/neglect to pay the tax on breathing. Have a happy!
jaredsalzano in reply to psychlonesJan 7, 2013. 10:33 AM
Against the constitution. Freedom of Speech.
_soapy_ in reply to psychlonesMar 21, 2009. 2:13 AM
You've at least got the right to free speech still, and have a body like the ACLU which has actual sway with politicos.

Both our right to free assembly and right to free speech were swept away in the last five years. Along with freedom from unreasonable search and seizure, every offence, no matter how minor, becoming arrestable, etc. Needless to say, the right to bear arms legally was crushed many years back. Now the police stop and search people and confiscate *anything* that could be used in the commission of a crime.

Try and think of anything that *cannot* be used to commit a crime. I can't. While thinking about that, think about joining the NRA and the ACLU. And think about boycotting the UK. Because that's where I'm talking about. And living.
psychlones in reply to _soapy_Mar 21, 2009. 4:08 PM
You are right except that increasingly the American public is willing to give up freedoms for a rather ephemeral "guarantee" of safety - I believe it was Benjamin Franklin who wrote: They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety" I was tempted to write a lot more and in truth just highlighted and deleted it all because this really isn't the forum for it. Instead, I will take a moment to thank all of you who stand up for your freedom to repurpose hardware in spite of draconian threats of IP laws that are now used as a sword to keep the implementation of ideas and creative works out of the public domain rather than a shield to guarantee their safe passage into the great marketplace of ideas as was originally intended. Thanks to all of you for sharing and in so doing demonstrating that you will not allow your creativity to be stripped from you and criminalized in the process. Have a happy!
