In 2011 I made a bracelet with ducttape and LED's (I named it BraceLED. Duh.) The bracelet's clasp is a small magnet that also acts as a switch, so the leds only light up when you're wearing the bracelet.

This spring (2013) a few things happened:
  • I did a workshop with high school kids, making BraceLEDs. And they really, really liked doing that.
  • That day I also met a man called Leen. He was there doing workshops with a 3D printer and... a lasercutter.

Two weeks ago, I did a nighttime workshop (from 8 pm to 1 am...) with adults this time, again making BraceLEDs. And them too really, really liked doing that.

Funny thing: Although "bracelet" sounds like "for women", braceLEDs are equally popular with men and women, boys and girls. Being able to design your own helps with that, I guess.

So: Many people enjoy making BraceLEDs and Leen has a lasercutter: Last week Leen and me joined forces and made a new version of the BraceLED, with the aid of Leen's lasercutter. We'll be doing try-out workshop with kids on June 22nd. I hope to have some pics of kids' results by then. In the meanwhile, here's a video to show how the clasp / switch works:

If you have access to a lasercutter *), making the BraceLED will take 30 mins to 1 hour. Costs are around €2,00 per BraceLED, but there is a catch: Although you need only 30 cm of coppertape, you must buy a 15ft roll if you don't have it lying around. And that will set you back around €8 (US$10).

This I'ble is an entry in the Epilog Challenge. If you like it, please give it your vote (you can vote for as many I'bles as you like). Thanks!

*) If you think you _don't_ have acces to a lasercutter: Lasercutters tend to nest in FabLabs, Maker Spaces, Hacker spaces or Tech Shops. Look for them in in your area. 

Step 1: Tools and stuff

  • Black markers / sharpies with a big tip
  • Soldering station
  • Scissors and / or knife
  • Cutting pliers
  • A laminator (only needed if you make the BraceLED of laminated paper)
  • Lasercutter
  • Software: a vector based graphics program like Adobe Illustrator, Corel Draw, Ink Scape
  • A scanner or photo camera to get your design into a computer

  • Ducttape in various colors, or:
  • Plastic coated paper
  • Copper tape
  • 6 to 12 LEDs. Any color you like. I use mostly red, yellow and green leds for workshops because they're cheap. Blue, white and RGB-leds are more expensive. You can even use blinking leds if you like.
  • Coin cell battery, 3 Volt, model CR2016 (Buy smart! Prices differ from €0,44 to €2,95 a piece!)
  • Supermagnet (disc shape, 15 mm diam, 2 mm thick)
  • Double sided sticky tape
Where to shop:
  • Coppertape: Conrad, (Europe only. If you know a link to a US shop, please let me know). Avoid 3M's shielding tape. It's great stuff, but really expensive.
  • Magnet: Supermagnete.com
  • LEDs: Anywhere (Radio Shack, Conrad)
  • Ducttape: Duck Tape (the brand) comes in _any_ color you like :-) I bought it at my local hardware store, €5 for 10 meters. Amazon is waaaaaayyyyyyy cheaper!
<p>This is incredible! I love it!</p>
<p>Glad you like it. And thanks for the patch :-D</p><p>Y.</p>
<p>Btw, I just read your profile and noticed you're a teacher. Did you do this with kids?</p>
<p>You're welcome! I have done work like this with kids - designing and rapid prototyping with a laser cutter and 3D printer. My previous job was at an Intel Computer Clubhouse and I spearheaded the creation of a makerspace there.</p>
Thank you for the tip!
Great project, great workshop idea, great Instructable!
:-) You know how to make me smile :-) Thanks!
Yup, you were right.... <br>I likeee it!!!
Told you so :-). Thanks!
He Ynze, great idea and looks fantastic.
Wow this looks awesome - great job!
