Was this really the best I had to offer? Couldn't I think of any more improvements? Something extra? Something to make it just a little bit better, easier, funkier?
Well, you know... Of course I could! So here it is, BraceLED version 2.0. And here's the video...
BraceLED 1.0 has a few (non-critical) problems, that are more or less fixed in this version:
- The LED's are more secure connected to the circuit.
- The layout and design of v2.0 is much more straightforward
- Because of that, BraceLED 2.0 is (even more) easier to make
- In version 1.0, switching on the led's is a bit awkward, using a loose supermagnet. It serves it's purpose, but elegance is a different thing. Version 2.0 solves this handsomely.
I will keep BraceLED 1.0 online, because it has it specific charms that are different or altered in this new version (I like the gap underneath the leds in v1.0, for instance). Perhaps the best of the two versions can be combined in something new... If you have any ideas on that, please step forward!
Step 1: Stuff you need
- Ducttape in a color of your choice
- Double sided tape
- 6-10 LEDs (5 mm). Pick your color
- Copper foil or aluminium foil, 25 x 10 cm (10" x 4")
- 1 Button shaped battery. Bigger is better (in this particular case), so pick a model like 2032 or 2450
- 1 Super (neodymium) disc magnet. 20 mm diameter, 2 mm thick. Europeans: shop at www.supermagnete.de
Total costs: €8,- / US$ 10,- maximum when you use aluminium foil. Copperfoil is expensive.
I got the copperfoil a loooooooooong time ago at a metal-supplier in Rotterdam, NL. The foil is available in various thicknesses. Mine is 0.1 mm, I believe.
UPDATE Oct 20th '10: Until yesterday, I was unaware of the existence of adhesive conducting foil. It is solderable, and even the adhesive layer is conductive! Now, that sounds GREAT for making a BraceLED!
3M makes it, and so does Laird. The stuff is horribly expensive, though. Farnell dares to ask €40,-/US$50,- for a roll of 16 meters...
Tools you need:
- Cellotape (not critical, small strips of ducttape will do as well)
- Hobby knife
- Needle nose pliers
- Strip of paper to take the measure of a wrist
- Blunt stick / the backside of a pen
