How to make a LED heart minion necklace

 Minion Heart Necklace

Yet another unique gift for your special someone. What makes it unique is, it glows and blows minds!
Well technically, the LED's in the necklace glow when you press the pendant and also when you thread it to a metal chain. Here are the steps to make it.

 Here's a video of how it looks when its done: http://youtu.be/jx08CxBUhYQ

Prerequisite : Basic soldering knowledge.

Difficulty level : Medium

Things you will need :
1. 2x RGB LED's
2. 2x 3V Battery
3. Soldering iron and wire
4. Hot glue gun
5. Reset switch
6. Conducting wires
7. Texture white
8. Acrylic colors

#Steps:

Step 1: Take a general purpose PCB and cut two heart shaped parts.

Step 2: Take one part and design the circuit as shown in the diagram. Solder the LEDs in series with the battery (6V). Connect a switch between the terminals.  Make contact on the PCB for the negative terminal of the battery using small wire.

Step 3: Extend two terminals out of the PCB (to attach the necklace later) and solder the terminals to the circuit.

Step 4: Take the other part of PCB and make contact for the positive terminal of the battery.

Step 5: Place batteries on the terminals with the right polarities. Check and Make sure the LEDs glow before going further to make sure the circuit works.

Step 6: Join the two parts and align them properly. Use a pair of clippers to hold them firm. Use a hot glue gun to bind the two pieces together and seal the circuit. Make sure you leave enough space not too much not too less so that the switch works effortlessly after you hot glued it.

Step 7: Use a hot solder iron to smooth out and make the surface of the hot glue even and shiny. Apply a coat of Texture white to make the surface smooth and uniform. Let it dry.

Step 8: Draw a minion of your choice on the plain side with a pencil and use acrylic colors to paint it.

Step 9 : Apply a coat of varnish and let it dry and you are done!! Watch them glow!! ^_^

How to make a Minion

 Minion

Loved the Minions in the Despicable Me Movie? Well here is a way to make a paper mâché Minion and add a little pinch of electronics in it. By recycling a bit of scrap from your home, you can make your own minion dolls for play or display.

Difficulty level : A play in the park.

Things you will need :
1. Aluminium foil roll
2. Some old newspapers
3. Glue
4. Toothpicks
5. Pen refills
6. Some clay
7. Paint
8. Varnish

#Steps:

Step 1: Take an Aluminium foil roll and cut it in to a preferable size. Draw a rough face on it for reference.

Step 2 : Make a small circuit with an LED and 1k ohm resistor in series. Punch two holes at the back bottom of the minion and let the wires out out it. You will later connect a battery (5V) to these wires to turn on the LEDs.

 

Step 3 : Make a paper mâché paste and fill the Minion with it. To learn how to make paper mâché click http://www.instructables.com/id/Make-paper-mache-pulp . Punch two holes for hands around the middle and insert toothpicks of appropriate size.

Step 4 : Apply a coat of white texture using Acrylic color. It will give a good finish for painting the surface.

Step 5 : Attach two refills for legs of the Minion and make sure it will be able to balance itself in standing position. Use clay to make the boots and gloves.

Step 6 : Make the eye band using clay and paint the Minion yellow and blue as shown.



Step 7 : Use black color for the gloves and boots and the back of eye band. Colour the eyeband and the mouth.

 

Step 8 : After everything dries up, apply a layer of varnish for a shiny finish and to protect against dirt. Let it dry.

Here's how the Minion looks in the dark with the LEDs on.

Done!!! Add it to your art collection, keep it on display or play.
Make a whole army!
