Want to make a neat courier bag light? This light goes through the straps on a timbuk 2 bag and blinks in really cool patterns using a BS2.

Step 1: Materials

You'll need:
16 x 470 ohm Resistors
16 x LEDs
24 Pin IC Socket
on/off switch
9v Battery
9v Battery connector
9 x Molex KK Connectors
18" 3/4" Flat webbing
Breadboard
Wire... oh you'll need some wire.

Step 2: Solder

Solder the resistors to the 24 pin socket. You want to solder to pins 1-16 of the BS2, which starts at pin 5 on the socket.

When soldering the resistors it works nicely if you put them in vertically not horizontally.

Then solder the other end of the resistor to one of the pins on the connector.

Solder the positive to pin 1 and the negative to pin 2.

Step 3: Sew

Sew two loops in your webbing so it fits over the straps on your bag.

I used one end with a slide adjuster to it would be... adjustable.

Step 4: LED Time

Poke your LEDs through the webbing with the positive on the top and the negative on the bottom.

Step 5: Make It Stand Up

So bend the negatives of them all towards the center. Solder them together and hook them up to the negative power. This step makes the strap sit flat and gives it some shape.

Bend the positives up and solder each to the corresponding pin connecter.

Step 6: Load the Code

Load this code on to your BS2 and fire it up.
