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 itsee the video here: 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 gunnow 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.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 togetherattach the positive and the negative wires of the dc transformer to the positive and the negative side of the led stripfinally 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!!!
