Playmobil 3V LED Tester





Introduction: Playmobil 3V LED Tester

Attaching the leads of an LED to a battery clip is hardly amusing. This is my best attempt at livening it up a bit.

When you are done, all you will have to do to test an LED is place it in the hooks that you make with the wire.

Step 1: Materials

The materials are relatively easy to find:
  • Playmobil toy or any other plastic toy with arms.
  • AA Battery Clip
  • 2 AA batteries
  • Battery Clip
  • Wire splitters
  • LEDs

Step 2: Place Batteries in Battery Clip

Place the two AA batteries (alkaline or rechargeable) into the battery clip and test it with a multimeter. Make sure there is a solid 3.0V. This will give us the best results when testing the LED.

Step 3: Expose Metal Wire on Battery Clip

Take your battery clip and wire splice it a little less than a quarter the way down the lead. I also added a piece of hookup wire to the end of each lead to make the wire stronger at the ends for when we form the metal strands.

Step 4: Attach Toy to Battery Holder

Attach the plastic toy to the AA battery holder, with its feet on the plastic part of the holder. That way, we can remove the batteries when they die, and replace them. Or take them out and recharge them. I used hot glue to glue the feet down to the plastic part of the battery holder.

Step 5: Pretzel Knot

Just below the plastic part of the battery clip leads, make a pretzel knot for each of the red and black leads. Place this pretzel know around wrists or in the hands of the plastic toy. Make sure that only the plastic portion is in the knot, and also make sure there is a decent amount of plastic lead leftover on both sides of the knot.

Step 6: Twisting the Metal Lead

Now with each of the pieces of the metal parts of the battery clip leads, try to make a circular shape all while keeping a decent sized space in the middle. To make it stronger, you can wrap it around itself a couple of times. The pictures should help you out.

Step 7: Test It Out!

Find your LED, and stick it in the two holes of the battery clip leads. The shorter lead of the LED is the negative lead. The negative lead of the LED gets placed in the black lead of the battery clip.

    what the h--- is with the LOL doodoo?

    It just has to be Playmobile! My son spent a lot of time in the hospital when he was a child, and the Playmobile company sent my son little sets that helped him pass time while he underwent treatments. I'll always appreciate their supportand by the way...the PlayMobile Taxi (it was my son's idea)

    Very Nice!! Just a suggestion. Why not use some heat to gentle bring his arm closer together (approx suitable for a LeD), then run th wires up his back, along the underside of his arms, then in his palms. The you would have a little man which checks Led's instead of a little man holding a clip type device to attach the LeD too. You could cover the wire in white electrical tape to hide them under his arms... Like I said just a suggestion, I love him how he is though!! Great Work!!

    I was thinking that Lego men are narrower - I bet you could glue the wires under the arms, with bare wire in the palms.

    I'd try, but the boys won't let me use one of their men.

    Yes, I thought initially it was a Lego man. A Lego mans arm spread should be about perfect. You could run a bead of silicon in the palm and lay the wires on top forming the gripper... I really like this idea. If only I had some Lego men left!!

    lol, all mine either drowned, or deformed in my lego box...... also burned( never make a zipline lead over a lit lamp.....)

    Nice, very nice. If you wanna go out, you wanna go out on a zipline lead over a lit lamp. LoL

    Lol, most definitely.

    Great beginners project makes electronics a little more exciting looking.
