Step 1: Get your stuff together
Tools you will need.
Hot glue gun with lots of glue.
Wire cutters and strippers.
Soldering iron and solder.
Scissors or knife.
Supplies you might need.
Led. I used 9 green ones.
Altoids gum tin.
Power plug and jack.
9V battery snaps.
Cloth. I used old jeans.
I think thats it.
Step 2: Make a 9V power supply
Take your Altoids tin and flatten out the bottom to allow more room for the battery.
Mark outline for the power jack.
If you don't have on your safety glasses put them on NOW.
Use Dremel to cut hole.
You can use a small file to cleanup the edges.
Step 3: Make a 9V power supply
Now solder the 9V battery snaps to the power jack.
I used heat shrink to cover the terminals but hot glue would work.
Insert the power jack in the hole and glue it.
I also glued Velcro to the back of the tin.
Step 4: POP THE KEYS
Pop the keys out of your OLD keyboard.
Do it . Its fun. Pop.Pop.Pop
Pick the keys you want and drill a hole in them for the LED.
I also used a small round file to help make the LED fit.
For the keys a phone number would be good but I used my dogs name plus the "help" and
" return" keys for this one.
Step 5: GLUE THE KEYS
Nibble the pegs off the backs of the keys.
Insert LEDs and glue.
Step 6: Now the collar
Trace the collar on the cloth.
The idea is to make a sleeve for the collar, so leave enough material to wrap around. Set the collar aside.
Cut the cloth and layout your keys and power supply. Leave space between the keys so the collar can flex.
Mark on the back of the cloth where the LEDs will poke through and cut a small X .
Poke the LEDs through the top of the cloth and glue into place.
Hot glue burns!
Step 7: SOLDER IT
I used the current limiting resistor calculator
to figure out the resistors to use.
I used 9 LEDs.
3 sets of 3 LEDs soldered in series with a 180ohm
resistor for each set.The sets were then soldered in parallel.
I then covered all the wires with hot glue,
Step 8: FINISH IT UP
Wrap the cloth around the collar and glue it.
I glued Velcro on the end of the cloth to attach the power supply.
Well, you should have tested it by now to prove that it works.
Now put the Super Fantastic LED Dog Collar on your dog .
Step 9: TAKE LOTS OF PICTURES
Take pictures and have fun.
Go outside in the dark and run around!
May cause social situations!
