Need help with a project involving lasers, Arduino and FPV

I've no idea how to do what you want, but just wanted to mention, what the guy did popping balloons in the video might look like a fun game for a few minutes, but it's quite dangerous - one reflection and it could cause permanent eye damage.

If you really intend to do this (and I'd advise not), notice he's doing it in a different room with a camera, which is a bit safer but still someone might step into the room unaware.

There are a lot more fun things with lasers which can be done with lower power red laser pointer type diodes. But better to just start with arduino basics and learn how to control LEDs and motors, etc, i.e. baby steps first to learn electronics and software programming.

Agreed shabaz

Not even going to watch the video as your comments are enough....

I suggest you start off by searching for "Arduino tutorial" which nets about 3,790,000 results in google.

There are also references to tutorials here under the "Arduino" area.

The old saying you need to walk before you run applies well here.

There is nothing more satisfying than planning something and executing it, even if its only blinking an LED.

If you wish to copy someone elses work, then there are also plenty of projects out there that will either give you everything, or most of what you want.

Totally agree with shabaz.

You would be better off making use of LEDs or VERY low power lasers, especially for a learning and development project. I've seen and heard of too much damage when it comes to inexperienced laser operators. Somebody's eyesight is a difficult thing to fix.

If you wish to construct a search and destroy drone you might benefit from building some laser-tag style targets. These can be designed to produce a light or sound when hit with a low power laser. The laser beam duration can be much lower than that required to burst a balloon and this will reduce the risk to others.

This page would be a good place to start looking at maximum exposure times and laser safety in general: Laser safety - Wikipedia, the free encyclopedia

If the laser used in that video is 2W then it would likely fall under Class 4.

How about a movement sensor,small cam array or Ping sensor been scanned using a servo.

Get it to recognise the car been moved and to track it with a low power laser from a pointer so you can still have a chance of seeing properly afterwards

Agreed I would be trying out the Arduino demos in the Arduino Playground understand this and integrate what I learned in to the main project.

Otherwise you are just getting some one to do your project for you which is basically pointless in the long term.

Hi!

Yes, even basic demos like blinking LEDs can be modified and used to good effect - e.g. try long-range comms with it and lenses and a photodiode - would be fun : )

Suggestion: Use IR which is below visible light and easier to control as well as safer! With an IR receiver/sender pair you can play interesting games.

You are right but thinking on it  how about red and say green less with two filters a red and green one on the receiver demonstrating light communication filtering due to colour and full duplex as well.

I think visible light is more appropriate for a demo or project because it can be seen by the examiners.Flashy lights make points
