Even though it is probably one of the smallest and easiest projects you can do it is still fun to play with and point all around your room at night. The project is very simple and uses no switches it just has these wires with the extra plastic wrap near the lead, that makes it so that you can just press it and then it turns on.

Step 1: Components Needed

To make the mini laser pointer you need to have:
• two cell batteries
• a lot of electrical tape
• a 5mw laser diode with two wires pre-soldered to the laser diode
I'm not sure maybe an hour to two hours
<p>Great idea! How long do your batteries last?</p>
