How to Build a Laser Comb

Hair loss is something that affects millions of men each year. A laser comb has been touted as an effective and non-invasive treatment for stimulating the hair follicles to encourage growth. Building your own laser comb will save a great deal of money as well as providing a sense of accomplishment that will encourage you to use the laser comb on a regular basis. Hair growth may or not occur but at least you will be doing something about the problem.

Instructions

Preparing the laser diodes

• 1

  Put the cloth down on a work surface. Twist open a laser housing and put the front half of the laser housing down on the cloth.

• 2

  Hold the back half of the laser housing straight up. Remove the exposed laser diode using the tweezers. Insert a 5mW 650nm green laser diode into the vacated space where the original laser diode was removed.

• 3

  Strip the insulation off of both ends of the black and red wires using the wire strippers.

• 4

  Heat up the soldering iron. Solder a black wire to the positive contact of the laser diode and a red wire to the negative contact of the laser diode.

• 5

  Run the two wires through the front half of the laser housing. Screw the front half of the laser housing back onto the back half of the laser housing.

• 6

  Take the five remaining laser housings and repeat the process of unscrewing them, removing the laser diode and replacing them with a 5mW 650nm green laser diode, soldering on the black and red wires and closing the laser housings back up.

Making the laser brush

• 7

  Place the table tennis paddle down on the cloth.

• 8

  Glue each of the six laser housings in a small circle on the mat area of the table tennis paddle using the bonding glue. Let the glue set.

• 9

  Solder a black wire from each of the laser housings to the positive contact on the "D" cell battery compartment. Solder a red wire from each of the laser housings to the negative contact on the "D" cell battery compartment.

• 10

  Attach the "D" cell battery compartment to the handle of the table tennis paddle using electrical tape.

• 11

  Insert "D" cell batteries into the battery compartment to light up the green laser diodes.

• 12

  Pick up the laser hair comb and slowly move it back and forth over your hair starting from the part in the hair and then returning back to the part.

• 13

  Continue using the laser comb for up to 5 minutes. Remove the "D" cell batteries from the battery compartment to turn off the laser comb.
