Hello everybody,
I have a laser which I want to use in a project. It is cheep and hard to find and the ones in the same class which are easy to find are really expensive and exceed the projects budget. Here is the picture
It is a 3mW laser and the input voltage is 3V. I want to supply the voltage from 2 AAA size 1.5V alkaline batteries.
My first question is: is there a problem if I use the batteries and a switch. (I assume the switching on and off can cause some problems as well as the battery itself)
Second: I think about using a linear voltage regulator and some capacitors to keep the voltage stable but I could not find one which has 3V output voltage but 3.3V.
ok, I will be happy to hear your ideas.
