DIY Christmas Lights Set To Music - Choreographed House Lights
This is NOT a beginner DIY. You will need a firm grasp on electronics, circuity, BASIC programming and general smarts about electrical safety. This DIY is for an experienced person so I will not go into detail about how to solder or how to read schematics etc. Sorry, it would take way too long to write an instructable that included schooling in electronics.
Here is a DIY to make your house christmas lights Choreographed to any song you want. It's not easy but if you're good at electronics YOU CAN DO IT!
Step 1: The Components
To get started you'll need 16 MOSFETS, 16 Relays rated at 9V 10A, blank PC board, Cat5 wire, hot glue, a transformer rated to drop down 110V to 9V a bridge rectifier and Capacitors from Radio Shack.
Step 2: Schematic
Here's a diagram of the circuit you'll need to build. It's basically a transformer to power the 9V relays. Then a microcontroller (later steps) will send a signal to the MOSFETS which will then activate the relays which will turn the 110V power on to the individual plugs.
Step 3: Mechanical Relay Pack
Heres a picture of how I wired the relay pack. You can put them on a board if you want. I used CAT5 wire for all low voltage circuits and 12GA wire for the 110V applications. I recommend hot gluing all wires together to keep them from bending or breaking.
Step 4: Relay Pack
Here's another pic of the relay pack with the rest of the board we'll build soon.
Step 5: MOSFET pack
Here's the MOSFET pack on the circuit board. You'll have to be creative when wiring them. If you like to etch your own board you cn do that but I just used wires and solder.
Step 6: Wiring the MOSFETS
Here's the underside of the board where I wired the MOSFETS. I used 3 pieces of CAT5 wire. You can see the blue CAT5 wire to the left and right. This keeps it somewhat neat and organized.
