Introduction: Musical Hearts
This project is an closed circuit set up that allows people to plug in their phones to an aux cord and play music that has strong bass. The bass from the music allows the circuit to close which cause the lights to flash along.
Step 1: MATERIALS
- 3 pieces of wood (12" by 12")
- Scroll Saw
- USB port hub
- Drill with 1/4 inch drill bit
- 100 grit sand paper
- White Acrylic paint
- Paint brush
- Soldering Iron and Solder
- 120V AC Plug (Male)
- 120V AC Plug (Female)
- Speaker Wire
- Solid State Relay
- USB Lights
Step 2: Designing the Hearts
1. Pick your wood for this project. We used Pine, however cedar wood is another option.
2.Find one heart shaped clip art online. Put it into a word document to change the size of the heart, then print it off then cut out the big and small heart shape from the paper.
3 Put the heart on the wood and cut out the heart shape into the wood. you can either sand the wood you are going to cut first, then using masking tape cover the wood which final allows you to glue the heart on to the masking tape allowing you to cut it the heart that way. The 2nd option is simply tracing the heart you printed, this although is a faster method does have allow for a higher chance of mistakes.
4. Take an electric drill, using a 1/4 inch drill bit, drill holes randomly (or in a pattern) into the heart to create enough space for the lights to fit just enough.
5. If you did not choose to sand and tape the heart originally now is the best time to take 100 sandpaper and sand the top, sides and the holes for a smooth surface, to prevent being poked by the wood we recommend that you sand the edges of the heart to create a dull and rounded finish.
Step 3: Painting, Stands and Lights
1. This is a really quick and easy step to do. We used white acrylic paint, we ended up choosing to do 2 layers of paint to cover up any of the mistakes that happened while drilling.
2. Once the paint has dried you can put stands on the back. Our choice was 3 inch hinges with small screws for the small hearts. For the bigger heart we used a metal support brackets.
3. The lights we bought online through amazon. The name of the lights are Kohree LED String Lights,USB Powered Multi Color Changing String Lights. The metal wiring on the lights are very easy to manipulate to fit into the drilled holes. To keep them set in the spot you can use super glue but if you eventually want to take them out you can simply use tape.
Step 4: Connecting the Music to Lights
For this section we had help from another instructables
Although we did use this as a guideline we did slight variations to ours. We did not use the switches on our project, and instead of soldering everything we simply used electrical tape to connect parts together to save time.
Step 5: The Finishing Touches
