Introduction: 99¢ Foppy Power Connector LED Bouquet Jawn

This is a bit of junk art, patched together with old floppy drive power connectors, a spare USB printer cable, and less than 1$ of LED's & Resistors.

Step 1: Gather Your Supplies

  • 20 LED's, Slow Flashing 5MM Diffused 7 Color
  • 20 47Ω Resistors
  • 10 Floppy Power Connectors
  • Heat Shrink Tubing
  • 5V Cell Phone Charger
  • USB Cable
  • Soldering Iron
  • Wire Strippers

Step 2: Start Stripping

  • Strip a generous amount (at least an inch) of cable from the base of the positive and negative cables
  • Make a second cut on the positive cables and slide it down as shown
  • Twist the negative leads together

Step 3: Solder Resistors

  • Cut the positive cable in half where you exposed the wire.
  • Solder Resistors inline as shown
  • Visually inspect or test your soldering before adding heat shrink

Step 4: Insert LED's to the Power Connectors

  • Add LED's to the power connectors, keep track of polarity
  • Common the negative (short leg) by twisting together, as shown
  • Fold the positive (long leg) up the side, as shown

Step 5: Prep Your USB Cable

  • Cut the end from a USB cable and strip the wires
  • Cut the data cables at different lengths to prevent short circuits.
  • Check the power cables for polarity, don't trust colors.

Step 6: Solder Your Bundles

  • Twist the Positive leads together and solder them
  • Twist the Negative Leads together and solder them
  • Solder the the power cables from the USB cable to the respective ends
  • Add heat shrink to the bundles

Step 7: Cleanup and Troubleshoot Loose Conections

  • Power up your Bouquet from a wall cell phone charger or a USB power bank.
  • Tap the LED's, if the color changes back to red or off, you need to fix the connection.
  • The Negative cables should have 50% less problems. (I had zero bad negative connections)
  • Twist some solid core cable and stuff it up the bottom to insure good contact.
  • Snip the solid core cable and positive leads flush, as shown.
  • Leave the negative exposed

Step 8: Make a Base, Because You Are Done.
