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
