Do not go gentle into that good night...without a pair of Freddy Fazbear Light Up Slippers.

From the video game Five Nights at Freddy's, bring the animatronic bear to life.

Don't let this project scare you.

It's only a simple LED circuit with a DIY pressure switch.

Step 1: What the Last Night Watchman Left...

I had a spare pair of brown corduroy-ish slippers that were perfect as the base for this project.

For the electronics you will need

a battery (3v or more) or battery pack

two LEDs, any color you want

a resistor for the LEDs

wire

alumiinum foil

tape

piece of thin foam or thick fabric

two ping pong balls.

usual crafting supplies

You can make this a true soft circuit by using 3.3v coin cells and holders sewn into the slipper. Substitute conductive thread for the hard wire.

No microcontroller needed but you can do it up with an arduino if you want.

CAUTION: Craft safely. Respect the soldering iron and hot glue.

Step 2: Warm Fuzzy Feeling...

You can mod any pair of slippers, shoes or boots.

I cut out some black felt dots to glue on top of the ping pong eyeballs.

Use bits of felt to make the top hat, eye background, eyebrows, nose and teeth.

Attach those parts using whatever adhesive you have.

I used a double layer of felt to make the ears. I sewed a seam to give it that 3D ear look. They were attached to the slipper with small safety pins inside the fabric ear.

Step 3: Who Turned Off the Lights?

You can use any battery or portable power source. You just have to think of how you will attach it to the slipper and where it will be mounted. Since my slippers are especially big, my 9V battery can actually be shoved in to the front of the toebox and sit there. You can devise pockets or mounting straps for your battery pack.

Use any online "LED calculator" to design your circuit.

You want two LEDs (hopefully you know the tech specs or just go with 3.5v forward voltage/20ma current -white LED to use in the calculations) and crunch your numbers. It should give you the value of a resistor to use to protect the LEDs from burning out.

My two leds will be hooked up in series with a 130K resistor that I had on hand. Use whatever resistor value that is close to or higher than what the LED calculator specified.

I was too lazy to fire up Fritzing to make a nice circuit diagram but:

(+) -----------(resistor)---------------- (+) (-)--------------- (+) (-) -------------------------I

battery . . . . . . . . . . . . . . . . . . . . . . LED . . . . . . . . . . .LED . .. . . . . . . . . . . . . . .I

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .wire loops around

(-) --------------------------- (foil paddle)(foam spacer)(foil paddle) --------------------I

Note that LEDs will only work if the correct leads get hooked up with the right polarity coming from the battery. You can look for the longer lead or the smaller element inside the LED to determine if it is the POS or + connector.

Wire up and solder the LEDs in place mounted on the black felt eye cutout.

Make holes in the back of the ping pong balls. Stuff a tiny bit of fiberfill to help diffuse the LED light. I also scuffed up the plastic case of the LED with fine sandpaper to further diffuse the light.

Insert the LEDs and fix in place with hot glue or tape.

Wire up the resistor and the battery pack. With those components in place, you should be able to test your circuit to see if it lights up.

We can now make and splice in a pressure switch.

If you got long wires, strip off a few inches off the ends. I made some wire loops and soldered the loops closed.

Use a piece of tape to sandwich the wire loop to a piece of aluminum foil . Add another layer of tape on top of the tape to reinforce the pad.

For the spacer, use a piece of thin compressible foam or a thick fabric. I used a paper hole puncher and put a whole bunch of holes spread out over the foam.

Sandwich the foam between the two foil switch layers. The two foil pads should be facing inside toward each other.

You can now trim to size and lightly tape together.

When you press on the switch down, the metal surfaces make contact in the hole spacings and complete the circuit.

You can use the switch placed in the back of the shoe or the front, depending on when you want to lights to activate on a heel press or if you are a ballerina.

Step 4:

Once you have the circuit all wired up and tested to work, time to dress it up.

Use black electrical tape to cover up your wiring and make it less noticeable.

You can punch holes in your shoes to route your wires or just tack it down to go around the outside.

Position all of your components and sew or hot glue as necessary to fix them in place.

And there you go, a fancy pair of Freddy Fazbear Light Up Slippers.

Use the same technique with red LEDs if you want a pair of rabid Bunny slippers.

Tread lightly, one step at a time.

Enjoy!

<p>These are really cute and creative! Good job!</p>
<p>I protest firmly against this instructable since it opens the door to many accidental foot intrusions into smaller dogs, sleeping gently near the bed of older - or drunken - makers among us.</p><p>Help those poor, little, innocent, fluffy dogs!</p><p>Unfeature it now. Please.</p>
<p>Don't worry, those dogs will let you know one time to never make the same mistake again.</p>
<p>We have a proverb that sounds 'it's hard to talk with a beer barrel on your belly'. </p><p>What if we replace 'beer barrel' by 'foot', 'on' by 'in' and 'belly' by, well, eh.... </p><p>Just thinking..</p>
Thats cute
<p>You should see the Elmo ones with the metal razor teeth.</p>
<p>Awesome slippers</p>
