Step 6: Finished product and drawing examples

It works for me! Now drawing is another story.

To see what we have done, visit our website: LightDoodles.Com

See even more of our drawings on Flickr.

My next Instructable will outline our techniques for actually doing the art. In the mean time see the Write or Draw with Light Instructable.

<p>That is very very cool, you big kids! :) </p>
and how much is the time limit?
quick question, if this is using LED, how can I see my light drawings? <br>
Thanks for posting this! I loved this instructable and made several of these tools. I made the tubes a little longer so I could put 2 springs in and use AAA batteries with them. My wife and I really enjoyed them! Thank you.
beautiful art :-) I love your led-paintings
&nbsp;The aluminum foil dose not stay on!!! &nbsp;Why do we need it?
You are right, the foil is poor engineering and the lights stop working while drawing. I need to&nbsp;figure out a better system or buy&nbsp;something pre-made.
Sugru perhaps? Or maybe one of the other conductive putties. I would kinda like to see a version where instead of wire, conductive paint is substituted.
I left about an inch of wire exposed and wrapped a layer of foil around the lower 1/2&quot; of it.&nbsp; &nbsp;Then I folded the remainder of the exposed wire down over the foil and continued wrapping the foil around it.&nbsp; It stays really well!!<br /> <br /> Unrelated: I'm a teacher, and I&nbsp;did some light-drawing with my students for their classroom book.&nbsp; Would it be okay if I included a picture of your light pen collection?&nbsp; We have this explanation we wrote at the beginning of what light-drawing is, and your picture would help greatly!
Thanks Abbey. Feel free to use the pen picture!
This is sooooooooooooooooooooooooooooooooooo CLEAN tool loved it !
Thanks for the feature! We have received some great feedback. One fellow used the pens to create a marriage proposal. (She said yes!) We are now available for hire for your event, a photo booth from the dark side. See <a href="http://lightdoodles.com" rel="nofollow">lightdoodles.com</a>.

Awesome Instructable! I have sent a few people to this over the last few years. Also wanted to note that this type of photography is also known as Light Painting Photography or Light Graffiti. Picaso did a bit of this himself back in the 40's. Thanks for sharing your knowledge.
how do you see the product? Im confused... you cant drawin the air... so how do you see it?
When your camera takes a long exposure (example: 30 seconds), it captures all light for *30* seconds as one image. Perhaps a different way of thinking about could be: Imagine everything your eyes saw for 30 seconds were merged into one visual. Moving lights (especially in the dark) during long camera exposures create trails, showing you where they have been.<br> <br> Have you ever noticed during camping or in a power outage, a bright light (flashlight,lantern,etc) used in very dark places can leave visual &quot;tracers&quot; that lag slightly behind the moving light? Similar concept. Reflecting back onto people who pioneered this art form:<br> <br> <a href="http://life.time.com/culture/picasso-drawing-with-light/#4" rel="nofollow">http://life.time.com/culture/picasso-drawing-with-light/#4</a><br> <br> Wonderful idea!&nbsp; I don't have the tubing on hand that you used, but I do have 30' or so of garden hose.&nbsp; Your results are incredible.&nbsp; Thank you for sharing your creation!
It <em>is </em>confusing. You <em>can</em> draw in the air. <em>You</em> can not see it but the <em>camera</em> can.&nbsp;Drawing in the dark&nbsp;is like drawing with your eyes closed.<br> <br> Picture the image in your mind and when you draw, the camera captures all the light from the pens&nbsp;and creates&nbsp;a complete picture.<br> <br> Hope that helps.
I received a thank you email yesterday from someone that used this tutorial to make the tools for a marriage proposal video drawn with lights.<br> <br> Quite an honor.<br> <br> Check it out: <a href="http://vimeo.com/31670713" rel="nofollow">http://vimeo.com/31670713</a>
Thanks for sharing all your hard work! So impressive, unique, and fun! Have a perfect fall day!. Sunshiine
hi, how much are they to buy in australia ?
<br>LED ALADDIN Limited <br> <br>All light sources in our houses or at work must give an appropriate amount of light depending on the type of activities we perform. While working on a task that requires medium concentration the illuminance in a room should be at least 300 lx. The desks and keyboards while working at a computer should be illuminated with about 500 lx and while performing tasks that require high precision and concentration the luminous flux density should be about 750 lx. For comparison the amount of light that is enough for relaxing and watching tv is about 20 lx. Under this value the human eye is not able to recognize the features of a face. <br> <br> <br> <br>Examples of suggested illuminance in rooms <br> <br>Living room <br> <br> 1.main lighting: 100-200 lx. <br> <br> 2.surface of a table for reading and writing: 300-500 lx. <br> <br> 3.dining table: 300-500 lx. <br> <br> 4.computer stand: 500-750 lx. <br> <br>Kitchen <br> <br> 1.main lighting: 200-300 lx. <br> <br> 2.under shelf lighting: 500 lx. <br> <br>Other rooms <br> <br> 1.hallways, stairs: 50-100 lx <br> <br> 2.bathroom and toilet: 300-500 lx <br> <br>Other exemplary values <br> <br> 1.facial features recognition: 20lx. <br> <br> 2.sunny day: up to 10 000 lx. <br> <br>Multifunctionality of lighting <br> <br>While designing lighting in a house or flat it is important to keep in mind, that very often one room is used for many different kind of activities. For example a living room is a good place to relax and watch TV (where a subtle, slightly diffused light is most appropriate) but also for family meetings and meals for which the luminous flux density should be about 300-500 lx. This is why we should not limit the light sources to only one, but to few different lighting points that can work independently from each other. <br> <br> <br>Many sources of light in one room <br> <br>Due to the fact that most of the rooms in our homes are used for different activities, it is suggested to use multiple independent lighting circuits. A very good solution, that is more and more popular in interior design, is diffuse lighting. Diffused light may be produced both by a reflection of light from a completely nonspecular surface and by using multiple small point light sources. <br> <br> <br>Energy efficient and environmentally friendly <br> <br>While designing the lighting in a house it is good to choose light fixtures that can work with energy saving light sources. This environmentally friendly lighting not only helps to save money, but it is also shows our care about the environment. <br> <br> <br> <br>Good quality light sources <br> <br>We should always remember to choose good quality light sources. Very often a theoretically cheaper light source is actually more expensive because of its shorter lifetime and because its performance is much lower than stated by the manufacturer. <br> <br> <br>Contact LEDaladdin <br>LED Aladdin Limited <br>No.406 HongTeng Building, <br> <br>No.392# Xihong Rd,Gulou. <br> <br>Fuzhou,Fujian. <br> <br>350002 <br> <br>China <br> <br>Tel. : +86 591 6310 1956 <br> <br>Fax. : +86 591 2285 5952 <br> <br>E-Mail : info@LEDaladdin.com <br> <br>WEB: http://www.ledaladdin.com/index.html <br> <br> <br> <br> <br> <br> <br> <br> <br>
Really cool 'able and awesome doodles! I'm trying to build some of these for my brother who's a big fan of long exposure photography. I'm wondering if I have to get the super-bright LEDs (the ones that say on the package &quot;do not look directly, can cause retina damages&quot;), or if the standard 8 or 10mm will do; I thought that by tweaking the picture's luminosity it would make the leds &quot;artificially&quot; brighter, in my case it's way cheaper (Radioshack doesn't exist here, so I can getby mail order 7 or 8 standard 8/10mm LEDs for the price of one super-bright LED), I'm also a total noob in electronics so I wouldn't be worried about burning a 5&euro; led. Any thoughts?
first i like to say sorry to have post here as a reply. for some reason i can use the add comment function. <br><br>second i would like to say this is a great project and i love your art<br><br>third i would like to recommend some of my idea for you to think about meaning:<br> a) why not for the light you can dim or make the led brighter for you to make a sense of depth in the picture. my recommendation is to use PWM using 555 ic.that way you can change the intensity of the light.<br><br> b) instead of having multiple light pen why not just build 2 light pin 1 being just white and the other one is using the RGB Led that could make almost any colour in the spectrum except for white. if you try making white with it, it would just turn its self so dim it would become off<br><br>there this one web page that give great tutorial about this led<br>but it use a microcontroller. but u can easily change it to use multiple 555 PWM<br><br>http://www.mbeckler.org/microcontrollers/rgb_led/
This looks awesome! I definitely want to try to do this. The problem? Choosing a camera. I've been doing some research and I'd like a camera that isn't too expensive, but that works well for regular pictures, not just exposure photography. One that caught my eye was the Nikon d40. Would that work as well? And do you have any recommendations for cameras?
Thanks. All you need is the ability to control the shutter speed and that can be done with almost any camera. The D40 has a manual contol mode. You should be able to get at least 30 seconds of shutter time out of it, if not unlimited.
Oh, okay. Thanks for the advice and for getting back to me so quickly! :)
would a samsung digimax 101 work? im not sure how to change the exposure, but would it work?
I bet your camera will work. It does not appear to have any manual settings for shutter speed but you may be able to fool it. (I found the manual for the digimax 101 at amazon here: <a href="http://www.amazon.com/Samsung-Digimax-101-Digital-Camera/dp/B00008KIW6" rel="nofollow">http://www.amazon.com/Samsung-Digimax-101-Digital-Camera/dp/B00008KIW6</a>&nbsp;Scroll down to &quot;Product Details&quot;.)<br /> <br /> First, turn the flash off (see page 37). If the room is dark enough, the camera will leave the shutter open for several seconds, trying to gather enough light to make a decent picture. That is when you can do some drawing. Put the camera on a tripod or on the edge of a table for stability. Try it with the flash on too which will let you see who is drawing.<br /> <br /> You may also get a few extra seconds by going to &quot;Exposure&quot; mode and cranking that setting to +2.0EV. That might force the shutter to stay open a little longer. <br /> <br /> Good luck and thanks for your question.
wow u have to move like super fast to draw those in the air tolatly amazing
&nbsp;They do it by setting the camera to stay open and sensing light for a really long peroid of time. So it captures all the movments of the light pen in one image. CReating the drawing. So they can move as slow as they like. :)
I made these a couple months ago and forgot to comment. Great instructable, one of the most highly detailed yet still relatively easy to make I've ever seen! Drawing is harder then it looks, especially because my Canon PowerShot A540 can only leave the shutter open for 15 seconds! It turns out my mom and younger sister are better at them then I am! They were also a big hit with my cousins. They loved them! Thanks!<br />
do you have to use the resistor ?<br />
Hi Marc,<br /> <br /> If the voltage is close enough, you can get away with not using a resistor. There is some resistance in the wire and internally in the batteries. And the components are fairly forgiving at these voltages and currents, but there are limits. There is lots of discussion on this here in Instructables.
i got bored so i stoped<br />
This instructable was my first dive into the world of soldering.&nbsp; They were a complete success!!<br /> <br /> I used 2 3V batteries and a 220 ohm resistor, but other than that, they're pretty much the same.&nbsp; The pictures came out great!&nbsp; Thanks so much for these!
how do you get a good picture? plz help!<br />
Well, first put the camera on a tripod or some stable platform, set the shutter to a long exposure and then&nbsp;experiment with the other settings (f-stop, ISO, focus), oh, and do this at night or in a dark room. For more details, check out <a href="http://lightdoodles.com/pages/drawing1.htm" rel="nofollow">this tutorial</a>.
&nbsp;5 stars
&nbsp;ummm... there is no way in hell i could ever make this! for one, i was probably drooling and lost in dreams when we took ohm's law in high school. for another, well....&nbsp;<br /> <br /> but im a big fan of long exposure photography, and my modified flashlight isnt helping any. anyway, can i buy this somewhere?<br />
&nbsp;btw GREAT instructable! and ur wife is talented! its not easy drawing in air.<br /> so kudos to the both of you:P
this is an awesome <em>light up pen</em>... i made alot of colors out of this idea and it made me think of new ideas to add to this................ YAY!
What is the exact LED # you used> I am having a hard time finding it. Thanks Chris!
From what I can read on the package, the company is NTE Electronics and here is their web page <a rel="nofollow" href="http://www.nteinc.com/">http://www.nteinc.com/</a>.<br/><br/>The part number is NTE30070.<br/><br/>You don't buy from them directly but if you click on &quot;Find Nearest Distributor&quot;, they list stores that sell their product. I bought mine from the local electronics store, but you can find many LEDs online much cheaper. Here is one site that looks promising - <a rel="nofollow" href="http://www.theledlight.com/led-specs.html">http://www.theledlight.com/led-specs.html</a>.<br/><br/>
&nbsp;Hi there, Im not w you can call an expert. Nevertheless Im soldering some for my kids' xmas presents. Im using different kind of leds: High intensity, Diffused, and multicolored leds. I think the important issue here is keeping an eye in voltage and result expected.<br /> <br />

This is awesome man! Congratulations!<br /> <br /> I&nbsp;have a question though.. would Mrs. Stuart prefer a single pen with a switch that allows her to select one of several colors? together with the other switch that blanks off the light completely, when the light is not required?<br /> <br /> Thank you.<br />
Those are so cool what an awesome christmas gift to give!!!!
