I will show you how to make an instructables watch which contains a a burning laser,
Best of all, this is an extremly cheap project. I was impressed by the quality of my own for the price i paid for these materials.
This is inspired by the 007 laser watch that was worn by James Bond .
***DO NOT POINT LASER AT ANY LIVING THING***
***ALWAYS WEAR LASER SAFTEY GLASSES WHEN OPERATING A LASER***
Step 1: MATERIALS
(1) Cheap watch(preferably plastic)- Got mine at the local McDonalds, but available at dollar stores too. (58cents)
(1) 5mw laser(any kind)- Walmart,Walgreens or Petsmart (about $2-6 depending on the type of laser)
wire (doesnt matter the brand or type, just plain wire)-Radio Shack($3)
(1) slide switch( any one will do)-Radio Shack(80cents)
A soldering iron
A3v button cell battery
super glue/hot glue/epoxy
Step 2: GUT THE WATCH
Then take out the paper that was in the plastic cover.
You will be replacing it with the instructables logo in the next step.
Do not throw out the paper, you will need it as a template for the following step.
Step 3: PRINTING THE LOGO
You can use the previous paper in the watch as a template.
then install the logo under the glass.
Step 4: GUTTING THE LASER
****WHEN YOU DO THIS, MAKE SURE TO NOT BREAK ANY OF THE COMPONENTS!! BE CAREFUL!****
First, you will unscrew the bottom cap of the laser and take out the button cell batteries.
Then unscrew the top lens if your laser contains one.
Next, take pliers and carefully twist the top of your laser until it becomes free from the housing.
