Gather your materials., Keep the law in mind., Drill the holes., Insert the laser diode into the casing., Add a power source to your laser., Attach the power source to the laser diode., Put on the finishing touches., Test your laser pointer.
Step-by-Step Guide
-
Step 1: Gather your materials.
Most of the materials mentioned in the things you'll need section can be procured at online shopping sites or hardware retail shops.
Some, such as the laser diode, can be found in other electronic devices such as a disk burner. -
Step 2: Keep the law in mind.
Many countries have laws governing the use and power of laser pointers.
You can even be prosecuted for having a laser pointer which exceeds the permissible power limit.
Be sure to keep the law in mind and tone down your laser pointer as and when necessary. , You will need to drill two holes in the casing.
Drill one on the top of the casing.
This will be the switch.
Drill another hole on the side of the casing for the laser. , Some casings come with laser diodes built in.
If your casing comes with a built in laser diode, check whether it is powerful enough for your needs.
If it isn't, gently remove the laser diode and replace it with a new one. , Any battery pack will do, as long as it is powerful enough. , You can solder pins on the laser diode to make the attachment easier. , Add a switch, and solder all the components to the casing. , Check whether it works.
If it doesn't , you may need to replace the power source or check whether all the components are attached correctly. -
