It would be a waste to leave the balance items at one corner, collect dust and hopefully some day later some people would discover it.
Remember my Blinking LEDs belt BLING???? http://shin-ajaran.blogspot.com/2009/10/diy-blinking-led-bling-belt-buckle.html
I found one of blinking LED on my pile of parts, very lonely and in need of some serious company.
Quickly, I use some heat shrink tube, a 5mm blinking LED, 2x 1.5v button size battery and 10cm of the fibre optic cable to make a bangle. Very cool when used in dark environment.
If you wonder how it works.... check out the video below..... BTW, I took this video in my office with lights switch off and most importantly, in a very dark corner (below my desk). With fluorescent light (read: good for reading book), the light from the LED is barely noticeable.
1x bling LED: $0.5
2x 1.5v battery: $2
10cm fiber optic cable:$1.2 ($12 per meter from SLT B1 Continental electronics)
time:10minutes (OK, I din factor in my wage. Because now is wayyy pass 5pm.)
total cost:$3.7
