Friends have regularly recommended books as being particularly illuminating, but I admit that after opening them I was as in the dark as ever. Since I’m not one to let a good metaphor go unmolested (and because design schools seem to constantly create designers who’s job it is to make ugly lamps) I made this.

*Thanks to Boing Boing, Make, Craft and all the other sites for featuring this project, and to the Instructables community for voting it as a finalist in the LED contest!



It turns off when its closed and gives off a variable amount of light depending on how far you open it, up to about a 40W light equivalent. It gives a nice warm, soft light and it looks right at home on my bedside table.

Step 1: What You Need

Skills:
  • Basic soldering. 
  • Basic wood cutting.
  • Measure stuff reliably.
  • You have to be wiling to scalp a book.

Time:
A couple of afternoons, though a lot of that time is waiting for glue and paint to dry.

Materials:
  • Hardback book. At least 1″ thick. (I got mine from the local thrift store.)
  • 1/4″ plywood or MDF (About a square foot or so should do it.)
  • Wood glue.
  • White or clear 2-part epoxy.
  • Smoked or sign white acrylic, 1/8″ thick and as big as your book. (I got mine from Tap Plastics.)
  • http://www.diodeled.com/products-view.php?id=16(I used this one from SparkFun because its small and sensitive.)
  • 2.1mm female panel mount plug. Like this one from Mouser or this one from Jameco.
  • 12v 600mA power adapter with a 2.1mm make plug. (Like this one from SparkFun)
  • 22 gauge (or so) insulated wire. Stranded or solid core.
  • Flexible warm white LED strip. You’ll need enough to be double the width and height of your book. I bought mine by the inch at the local hardware store, (this is what it is,  but they only sell wholesale.) If you can’t find it there, these from Phenopix are similar. You can also find other suppliers at this search. You don’t need waterproof, regular watervulnerable is fine.
  • White acrylic paint.
  • Electrical tape (ideally white)
  • Either a) Off-white linen & white glue or b) Ivory or white acrylic paint. Thick, from a tube, not a bottle. This is for simulating the outside pages. Paint is easier to do but it doesn’t feel as nice.

Tools:
  • Craft knife
  • Soldering iron and solder.
  • Pliers.
  • Clamps.
  • Square.
  • Drill.
  • Fine grain sand paper (220 or so.)
  • Wire cutters.
  • Wire strippers.
  • 1″ paintbrush.
  • Saw.
  • Pencil.
  • Ruler.
  • Tape.
Thanks for this awesome Instructable!<br>Was great fun making it, thinking of building another one :)
That's fantastic! Thanks for sharing it. <br>(And a great book title!)
<p>It would look pretty <em>&quot;cool&quot;</em> if it was made with a laptop screen</p>
<p>Sensational. Love, love, love it. It makes reading a book look like fun.</p>
<p>well ,this is great idea to make such light ,although we are a professional lighting manufacturer in China,we don't know can make this kinds of decoration light for home use .but if anyone need this kinds of light use inside ,i mean led strip ,we can offer ,contact me sales01@lslledlight.com here is our web:www.lslledlight.com </p>
<p>Excited to make mine. Thank you.</p>
<p>wauw this is great!</p>
<p>With a few extra components the book cover itself could act as your power switch.</p><p>You will need a magnet, reed switch (with Normally-Closed contact)</p><p>, and small relay could be used in place of a traditional switch.</p><p>Attach the magnet inside or on the inside surface of the book cover.</p><p>Attach the reed switch inside the diffusor near where the magnet is on the book cover.</p><p>Then wire the reed switch to control the coil of a small relay. The relay contacts are wired Normally-Open to the LED strips.</p>
<p>The snap action lever switch already allows the book cover to work as the power switch with many fewer parts. </p><p>However your solution has the benefit of being a little less visible.</p>
I like the remark: &quot;You have to be wiling to scalp a book.&quot; There are other projects where you need to do that, like tablet-sleeves or netbook-cases. But all the time i'm hesitating. When it is a good book, i don't wanna destroy it. When it is trash, i don't wanna see the cover also. Has someone a good idea how to handle this inner conflict?
Hi <br>Your projects are amazing. Oh here I can&rsquo;t help sharing some experience of fabrication after designs done. <br>We are working with a <a href="http://www.zetarmold.com/" rel="nofollow" title="OverMolding"> OverMolding</a> vendor in China the name is Zetar Industry (http://www.zetarmold.com), Located in Shanghai China (a very big modern city). They are really good.Moving fast and very professional. They helped me with my new design. I asked them to do the injection mold, then <a href="http://www.zetarmold.com/" rel="nofollow" title="Injection Molding"> Injection Molding</a>mass production. I was surprised by their rich experience in <a href="http://www.zetarmold.com/" rel="nofollow" title="Insert Molding"> Insert Molding</a> <br>and punched lead time. Guys in Zetar deserve every good word just as you are.
I've been looking for a small bed light for my camper van that doesn't connect to my leisure battery and I have a small book box (a box that looks like a book that is) and a string of battery powered led's. hmmm. I think I know what my next project is. Thanks for the idea!

What level of transparency do you recommend ? TAP offers 20% , 30% etc.
I used 40%, though it's still kind of milky and translucent. I like that when it's off you can sort of see what's behind it. If you want to get rid of the milkiness go for &quot;sign white&quot; or 20%, though it will absorb a bit more light than the more transparent materials.

Yes,your point is great, if you are intresting in injection molding,please scan the next. <br>During injection molding, plastics may be subjected to an overload of heat. The result can be immediate decomposition and a very short lifetime. For a practical determination of their lifetime, plastic molded parts generally must go through a time period in actual service so reliable data can be obtained. However, the tests (usually per ASTM) used have a degree of reliability based on experience or as presented in an ASTM standard. If proper material and process controls are used, the parts might outlast predictions. <br>We are special in Plastic Injection Molding and Injection Molded Parts Manufacturer and please send email to: info@vulcanmold.com our website is http://www.vulcanmold.com <br>

Some plastics are more stable than others after aging, regardless of their initial shrinkage. In many cases, low shrinkage may indicate greater stability.

The operating sequence on many existing injection molding machines is to inject, hold, recover, and then decompress. Recovering with back pressure keeps the resin in the manifold under pressure. The screw decompressing afterward tends to decompress the resin in the barrel, not that in the hot runner.

Fortunately, any steps taken to save energy will also save money, in most cases. The traditional arguments favoring the silo are its savings on resin costs, labor savings through the elimination of handling bags and cartons, the savings of a costly warehouse inside floor space, and energy savings. For example, if a plant used a large quantity of resins but did not use silos, during the winter months bags or gaylords would be delivered repeat-edly through open delivery doors, and warm air would be lost. <br>We are special in Plastic Injection Molding and Injection Molded Parts Manufacturerand please send email to: info@vulcanmold.com our website is http://www.vulcanmold.com<br>

Great instructable as always Grathio... as far as the switch goes you could have used a magnetic reed switch and a magnet embedded into the cover for more of a clean design. I love it!
Thanks John!<br> <br> A reed switch is a great idea, would clean up the lines, and would help hod it closed when off. (Which wasn't a problem with this book, but could be a problem with some bindings.)<br> <br> Be sure to get a &quot;NC&quot; (normally closed) type reed switch which is a little harder to find than the common &quot;NO&quot; (Normally open) switch. That will make sure it turns on when you open the book rather than off.
Yes!<br><br>I've been thinking of something similar since I made a book speaker. It would be awesome to use a flex sensor or a linear potentiometer that would control the light level depending on how far the book opens.
Awesome project...I think I'm gonna try it :)) Thanks for sharing :))
Now that, is cool!
