Hi my name is Stan Maiberger My question/ Is their away to make as small a receiver as possible to turn a small lasor beam on and off with a 3 to 6 volt battery switch would be simuler to a small wireless romote toy on and off switch

Hi Stan,

Yes, this should be possible. Do you have a specific laser module in mind? What kind of range do you want for the wireless?

The laser would be a small laser the( laser receiver disk battery) have to be kept as small as possible the receiver and switch would be less than 10 foot apart and in the same room.

Hi Stan,

If I understand correctly, you already have a laser that is battery powered and just want to turn it on an off with a remote switch.

The easiest way would be to use this key fob and wireless relay:

• robotshop.com/en/315mhz-wire … RB-See-236
• robotshop.com/en/seeedstudio … =RB-See-71

However, the wireless relay requires a 12V DC power source to work, so wouldn’t be that compact.

If you need something smaller, you might need to consider building a custom circuit using a wireless set like this:

• robotshop.com/en/seeedstudio … RB-See-148

If that’s not good for your application either, would it be possible to do something simple like connecting a switch to a 10-20 foot wire which will be connected to the laser? This solution is obviously not wireless, but it’s easy and one of the most compact…

Hope this helps,
