Hey guys,
I'm new here and at the electronics world. But I understand a little!
I just found an old projection clock here in my messy place and opened it to see if the projector and the radio clock were separated things. I found that the only connection between both is 1.5, L+, L- and G. So I would like throw the radio away and keep the projector with a new power supply. The projector clock and the radio clock work separately, you need to change time on each one at a time and there's nothing that you can set on the radio clock to show on the projector clock. The projector has it's own setting buttons. But my doubts are:
1 - Does 1.5 and G mean 1.5V + and -? Could I connect to a 1.5V battery and test it?
2 - What does L+ and L- mean?
Here are pictures of the PCB connection and the clock model (what's in my hand is the projection unit.
Thank you very much for your help! Hope someone can help me =)
