Step 1: The Master Plan
With the 'Share the love' contest going on, the plan came easily... put a burly throwie in a heart-shaped box.
As this is my first Instructable, I would welcome any comments, suggestions, and constructive criticism.
Step 2: Gather Your Materials
- Any kind of plastic container with room enough for the battery and led.
- Electrical or Duct tape
- Proper resistor (if you're upping the voltage)*
- An LED (mine's a burly 10mm superbright red LED)
- with LED's, you can pretty much hook them straight up to 3 volts just fine, but if you're going to beef up the power supply, be sure and calculate what kind of resistor you'll need. Here's a fantastic LED resistor calculator:
Step 3: Make Your Battery Light
Once that's taped up, you can test your light by touching the other resistor lead to the positive battery terminal, and the cathode (-) to the negative terminal.
Now that you know it's working, secure the leads to the terminals using your electrical tape, and get your LED adjusted to the best position.
Step 4: Put Your Junk in That Box!
Step 5: Relish Your Handiwork and Let Cupid Bask in Your Glory!
Some alternate features/methods could include:
- Multiple LED's in series
- Diffused LED to cut down on the 'bright spot in center'
- Wire in an on/off switch to make it last even longer
- Write a secret message backwards in white out on the inside of the box that will show up when illuminated!
- Make a frosted plexi sub-floor over the LED and make it into a tiny gift box (hmmm... wonder what you could put in it?)
Thanks for checking this out... enjoy!
Step 6: Update!!!
- Gather materials. I got the switch and additional LED from Radio Shack. I changed to a 3v coin cell power source, so I got a holder for it on Ebay. The only other materials I used were a Dremel tool with multi bit, soldering equipment, wire, and hot glue.
- Rout out a hole in the heart just big enough for the switch to fit through. I used hot glue to secure the switch in the heart.
- The switch is an SPDT, so it has three positions, two ons (outsides) and one off (center). I wired the cathode (-) from each LED to the negative lead on the battery holder. I then soldered a small bit of wire to run from the positive lead on the battery holder to the middle lead on the switch.
- After securing the battery/holder/LED apparatus into the heart with hot glue, the anodes (+) can be soldered into their respective sides on the switch.
- Upon securing everything, test to make sure it works, and aim the LEDs towards the center of the heart's top when closed.
- Go show off your new handywork!
