Laser pointers are a ton of fun!
When I was a kid, my family would always take me to laser shows. The lasers were so powerful they would light up the entire room with a beautiful spectrum of colors.
I would be mesmerized by the spectacle of radiant beams of light bouncing around with the music and the crowd cheering in synchronicity and I couldn’t help but feel happy.
It was absolutely hypnotizing. As an adult, I still love to play with laser pointers. They’re just as enjoyable now as they were then. And that’s why I fell in love with making my own DIY lasers.
Laser pointers are small handheld gadgets that emit a beam of coherent and narrow light. They are used for pointing and illustrations. Ordinarily, such gadgets are expensive to come by owing to their similarly complicated nature. But there is some good news though. They may be easily improvised.
For this to happen, you have to first assemble the necessary tools and materials. Then, you have to follow some detailed steps. Our guide here endeavors to furnish you with both details. We shall reveal the tools and materials you need then take you through some step-by-step procedures to improvise it.

Tools And Materials Required
You first and foremost have to gather these tools and materials:
- Flashlight body
- Laser casing
- Power source
- Laser diode
- Drill bits
Then, you have to follow these steps to have your way in this:
Step I: Gather The Materials
Start by gathering the necessary materials above. You will find them from the leading hardware stores, nine auction sites, and the leading consumer outlets. Be careful with the specifications as they have a say on the quality of the item you ultimately come up with. You may need expert advice to go about this.
Step II: Drill The Holes
Take hold of the casing now and drill two holes on it. Drill one hole at the top of the casing to act as a switch. Then, go ahead and drill another one at the side of the laser. Use a drill bit to do this job. Be slow and meticulous to prevent ever posing permanent and irreversible damages to the casing altogether.
Step III: Slot The Laser Diode In The Casing
Slot the laser diode now in the casing. It is important to note that some casings already have laser diodes built into them. If yours is such, you may have to ascertain whether it is indeed powerful enough to meet your expectations or not. If it is, go ahead and make use of it.
In case it does not meet your expectations, you may have to find a new one and use it instead. To do this, you are required to gently remove the laser diode. Then, find a suitable one and slot it in the space provided as smooth and gentle as can be.
Step IV: Link The Two Terminals
You have now come to the crux of the matter. Plug the positive (red) end of the battery into the diode’s red wire. Kindly ignore the circular metallic object that sits round about the diode. Then, go ahead plug the black wire (negative) into the diode’s bronze tab that sits inside the body of the flashlight.
After linking, tighten the joints with screws firmly to see to it that the wires do not escape or get overly loose in the process of discharging their ends.

The page contains the inspiration you need to handle not only this but many other relevant tasks.
Step V: Introduce A Power Source
You should now introduce a power source. The best sources of power may be batteries, mains electricity and the solar respectively. Of these, a battery pack appears to be the most suited for the job. Do give it a top priority in your search for the most trusted power source.
Upon identifying the right source of power, you should now go ahead and attach the same to your laser diode. You may use the solder pins for the job as this makes the entire process simpler. This process may demand that you make certain adjustments also come up with greater final outcomes.
Step VI: Lay The Final Touches
You are almost good to go now. Before you go, you may need to lay some final touches. Add a switch for instance and then solder all the constituent parts onto the casing. Make the soldering exercise tougher and more enduring to prevent the same from getting detached even when the items fidget.
Finish off the exercise by screwing the cap onto the laser pointer. Scrutinize the item thoroughly to find out whether there could be any issues that may demand further interventions on your part. Rest at nothing until everything is complete. Specifically, check the circuits to confirm that they are indeed intact and perfect.
Step VII: Test The Laser Pointer
The laser pointer has finally taken shape. Before you commission it for your use, you now need to test it. Power the switch on and use it to point to some illustrations. While at it, try also to vary the intensity of the brightness of the light output.
Then, check the range of the light output and the ease, or lack of it, with which it alters the directions in times of use. Make any necessary changes if you suspect that the item needs them before calling it a day. You are now good to go. Go now with confidence!
These items are very delicate and prone to the risks of signal interferences. You really have to do your homework right before you can confidently thump your chest and say you have succeeded. We recommend that you carry out numerous mock tasks to deepen your expertise and skill in this area.
