Cool DIY Infinite LED Tunnel

hi,
in this instructable i'm going to show you how to build a virtual "infinite" led tunnel.

this is my first instructable...i know it's not perfect....especially for what concerns the grammar:-)....however I hope that you'll like it

see the video here: http://www.metacafe.com/watch/865086/cool_diy_infinite_led_tunnel/

Step 1: Materials & Tools

the things you need are:
- wooden bar (80cm X 3cm X 1cm)
- copper wire
- 20 leds
- a semi-reflective  mirror
- an ordinary mirror (the same size of the semi trasparent one)
- a DC transformer (3V or the same voltage needed by the leds)
- glue

- saw
- soldering gun

Step 2: Cut

now cut the wood bar in order to create a square of the same size of the mirror but don't glue it,
also drill a hole for the power supply, as you can see in the picture.

Step 3: Led Strip

now build a led strip on the inner side of the square as shown in the picture(be sure to add also resistors as shown below)
than glue all together

Step 4: Connect the DC Transformer

attach the positive and the negative wires of the dc transformer to the positive and the negative side of the led strip

Step 5: Attach the Mirrors

finally attach the regular mirror facing the inner side of the frame and the semi-reflective mirror on the other side,and you will see an amazing led tunnel!!!
