Fun with the cat. Help with the laser.

Can I use this step up regulator

to control the power of this laser

using two alkaline batteries?
I want to make a laser for my cat to play with her.
I don’t want to burn my cat. That’s why I want regulation.

Forever beginner.

You can get decent lasers for $3, red, or $6, green.
No need to reinvent.

Yes. Your local petshop or grocery store probably has pet-toy lasers already in stock for a few bucks. Just grab one of those.

Those lasers are quite fun with frogs and toads. They can clearly see the dot on the ground and go after it thinking its a bug. They will chase the dot all over the place

Always thought that was kind of cruel. Not so much with cats though. They deserve it. They understand cruelty.
