The LED (minor) Artcrime Tutorial

Criminal mind...
None of the photos in this article are manipulated - they show real events. Just check out the instructions below, and you can be the one who enlightens your 'hood.

Ingen av bilderna i denna artikel är manipulerad - de visar verkliga effekter. Kolla bara in instruktionerna nedan så kan du också börja lysa upp din tillvaro.

The classic use of a LED, Light Emitting Diode is to weld it to a battery and a magnet and throw it stuck on something metallic, preferable out of people's reach.

LED lights comes in all sizes, strengths and colours. Some even blink. They are very cheap and even easily to obtain for free from scrap electronics. An excellent weapon of choice for the aspiring as well as already hardened art criminal.

Fig. 1 shows your basic needs. A LED, one or two button batteries (avoid using lithium batteries, they can be rather unhealthy) and a magnet, preferably a neodymium (a very strong magnet) such.

Assemble the parts (fig. 2 and 3), the LEDs long leg goes to + on the battery. Preferably weld it all together, but if that proves too much of a challenge, use tape and glue. In the picture a strip of gift wrap ribbon is placed between the two batteries working as a primitive one time powerswitch. Pull it out and let there be light.

Note! These things draw attention. Do not throw them in places which might lure people into danger. It's also your responsibility if your blinking LED in someone's exhaust-pipe is mistaken for a bomb or something - use your head and do cool stuff but stay away from causing damage.

Another effective way of delivering your LEDs to impossible places is to make a bola (fig. 4), tie the LED to a thread with a nut in the other end, swing the nut and amuse yourself by throwing it up a tree or something.

Note! Use a thread strong enough - but not too strong. Select a thread which breaks fairly easy so that no people or animal get hurt. Do not use fishing line.

Glue some of the Christmas decoration known as angel hair (fig. 5) to your LEDs in order to massively enhance their effect. This stuff works similar to fibre optics and adds a diffuse corona (fig. 6) to your lights.

Plastic glass such as Plexiglass or polycarbonate can be used to make signs or tags: Drill a hole for the LED in the side of the plastic (fig. 7).

Rub the side you want to decorate opaque with a piece of sandpaper (fig. 8 and 9).

Paint the motif of choice on the plastic with art masking fluid, which is kind of liquid masking tape (fig. 10 and 11).

Paint the whole thing first with silver paint (that makes the light reflect better within the glass) and then if necessary with some other paint to make it completely opaque (fig. 12). The paint should be as fluid and opaque as possible.

Let dry and carefully scratch away the masking fluid (fig. 13).

LED tags
With an electric scroll saw (they do not need to be that expensive) you can easily cut out plexiglass or polycarbonate figures, kind of mini neon signs, or neon tags. If you stack a few sheets of glass before sawing them you can swiftly "mass produce" enough figures to last all night.
You drill a hole for the LED and rub the pieces with sandpaper until they are opaque. Coloured plexiglass and white LEDs generally give a better result than colourless plexiglass with coloured LEDs.

LED artcrime tutorial

LED artcrime tutorial - plexi glass tags
Det klassiska användningsområdet för LED-lampor - Light Emitting Diodes - är att löda fast dem i ett batteri och en magnet och kasta fast dem på något av metall, helst utom folks räckhåll.

LED-lampor, eller lysdioder, finns i alla färger, ljusstyrkor och storlekar. En del till och med blinkar. De är väldigt billiga och även lätt att få tag i gratis från elektronikskrot. Det perfekta vapnet för såväl wannaben som den förhärdade konstgangstern.

Bild 1 visar dina basbehov: En LED, ett par knappbatterier (undvik lithiumbatterier då sådana kan vara tämligen hälsofarliga) och en magnet, helst en neodymmagnet (en mycket stark magnet).

Sätt ihop delarna (fig. 2 och 3), diodens långa ben går till batteriets pluspol. Helst ska grejerna lödas ihop, men är det en för stor utmaning så använd tejp och lim. På bilden har en bit presentsnöre placerats mellan batterierna, snöret fungerar som en engångsströmbrytare; dra ut och varde ljus.

OBS! De här grejerna orsakar uppmärksamhet. Kasta dem inte så att du lurar in folk i farliga situationer. Det är ditt ansvar om den blinkande dioden du kastat in i någons avgasrör misstages för en bomb eller nå't. Använd huvudet och gör koola saker men undvik skadegörelse.

En annan effektiv metod att placera dina dioder på omöjliga ställen är att göra en bola (bild 4), bind fast dioden i ett snöre med en mutter i ena änden. Sedan kan du roa dig själv genom att slänga upp den i ett träd eller något sådant.

OBS! Använd en tillräckligt stark tråd - men inte för stark. Välj en tråd som går av förhållandevis lätt så att folk och fä inte skadar sig på den. Använd inte fiskelina.

Om du limmar fast lite av julpyntet känt som änglahår (bild 5) på dina lysdioder ökar du effekten avsevärt. Det här krullet fungerar ungefär som fiberoptik och ger dina lampor en diffus aura (bild 6).

Plastglas såsom plexiglas och polykarbonat kan användas till små skyltar eller taggar: Borra ett hål för dioden i sidan på plastskivan (bild 7).

Slipa sidan du vill dekorera matt med sandpapper (bild 8 och 9).

Måla eller skriv ditt motiv på plasten med maskeringsvätska - det är typ flytande maskeringstejp (bild 10 och 11).

Måla allting med först silverfärg (den gör så att ljuset reflekteras bättre inne i glaset) och om nödvändigt sedan med en annan färg för att göra plastbiten helt ogenomskinlig (bild 12). Färgen ska vara så tunn och täckande som möjligt.

Låt torka och skrapa sedan försiktigt bort maskeringsvätskan (bild 13).

Bild 14: Med en elektrisk figursåg (en sådan behöver inte kosta mycket) kan du enkelt skära ut figurer i plastglas, som typ minineonskyltar eller neontaggar. Om du staplar några skivor glas innan du sågar dem kan du enkelt "massproducera" tillräckligt med figurer för att de ska räcka hela natten.
Du borrar ett hål för lysdioden och slipar plastbiten matt med sandpapper. Färgat glas och vita lysdioder fungerar bättre än vitt glas med färgade dioder.

W*o*w - your LED major"Artcrimes" are fantastic - I am glad I found your site - I have now built some LED Throwies and will follow your instructions to build some minor artcrimes myself- thanks! One question: what sort of silver paint did you use to give the reflective surface - do you have any brandnames or advice? Have you got any other tips - because we are going to build some for a music festival on 7/8 July 2006, so time is short. Once again thank you Rory

 

Posted by: Max Magnus 2006-06-30

Ordinary acrylic artist paint will do, the more opaque the better. MalZeit 880 silver is very good. Spray paint is even better; a thin layer chrome effect paint will make a reflector almost as good as a mirror.

 

Posted by: Rory McPherson Site 2006-07-03

Hi thanks for replying so fast to my last message. I just wanted to check on the procedure above. Do you have to spray the whole of the piece of perspex, ie the sides and back as well as the front? I made a couple of prototypes yesterday, but I had slightly rough edges on the sides - I think I would be right in saying that a better effect would be achieved if I polished the sides with wet/dry sandpaper? What do you think - I am waiting anxiously for more supplies to arrive... All the best Rory

 

Posted by: Max Magnus 2006-07-03

The whole point of applying silver paint is to make the light reflect - bounce - around inside the glass until it comes out through the areas you have masked. Dark areas inside the glass will absorb light making less light coming out through your image / text. Thus you will get the best result if you manage to cover the whole piece with silver paint.

 

Posted by: Rory McPherson Site 2006-07-04

Great that's what I thought and what I did, however some of the sides weren't polished (I know that the 'front' has to be scratched) so it wasn't that brilliant - but I am getting some more supplies and doing it again, hopefully more successfully. I am also going to tape the bottom of the LED to prevent light coming out of the bottom of the sculpture. Thanks again, RoRy

 

Posted by: Max Magnus 2006-07-04

Basically there are no rules when creating stuff, if it does what it's supposed to do it works, and if it works it works! Some light being lost or escaping isn't that big a problem, especially when making smaller signs. However, when making large signs you might need more than one LED, and the fading effects will be more noticeable, then it's more important to have a highly reflective interior. Taping or painting the bottom of the piece (where the LED goes in I suppose) is recommended, yes.

jag täkte bara fråga vart man får tag i lysdioder och markerings tejp någon stans?? >>peace<<

Wonderful use of LEDs. I've been working with them for several years now, as a personal and private art form. I can see now, just how easy it would be to turn these into a very public art form with a lot of impact. Excellent work, you have inspired me.

 

Posted by: kristine 2006-12-16

I'm facinated by this-thank you for posting such a simple tutorial on how to make such interesting things with LEDs.

 

Posted by: Taylor 2006-12-24

What thickness of plexiglass do you recommend and what size do you generally drill for the LED? Thanks!

 

Posted by: Taylor 2006-12-24

Also, do you know of any other way to cut it? Perhaps without expensive electrical tools? I can't think of any way around them, but I figure it's worth a shot asking.

 

Posted by: Max Magnus 2006-12-26

The glass need to be thicker than the diameter of your LEDs. You can of course use a wire saw, but it works soo much better if you invest in an electric scroll saw. You could probably find a working used one for less than $10 (I've seen new ones for $30).

Posted by: josh 2007-05-02

if you were going to do a larger piece and require more LED's, is there a way to do it with larger batteris. I am thinking of doing a wall piece.

 

Posted by: Max Magnus 2007-05-02

Use a battery eliminator.

nice creations and big idea..

 

Posted by: pulse 2009-08-10

looked for ideas to light up a colour tinted perspex panel, found the LED in the edge of the panel but this is not practical, any other ideas welcome please, nice work on here, keep it coming, great site now in my fave's
ciao
