Making a cardboard ghetto blaster with fancy flashing LEDs

Step 5Assemble

Assemble
Now you need to solder all the wires to the LEDs if you haven't already. Colour code the wires to make it easier to plug it all together. It's best if you "tin" the ends of the wires before soldering onto the LEDs - it's just makes it easier for them to bond.

Mark out the points around the speakers where the LEDs will reside and push the end of a pencil almost all the way through. Lay your circuitry in the middle of the box and masking tape it in place. Connect all the LEDs, and add a tiny piece of masking tape to hold each one in place and stop them being pushed back into the box.

Connect the battery up and masking tap it in place.

Here's a video of the one I made.
