Hi everyone, I'm after some expert advice on some electronics I'm trying to modify. I've got some solar powered lights that are not working. I want to tap into them and use an external power supply as the LEDs within will still be working. Besides this I want to have more control of when they come on and to make sure they all come on together.
Please don't give me any stick. Yes I could buy new ones or alternatives etc but I'm doing this because I enjoy tinkering with electronic stuff.......albeit very much an amateur.
The lights are for use in a block paved drive, hence the reason for wanting them to come on together.
So, I've taken a couple apart and attached a power supply to the rechargeable battery lugs. One started to work and the battery started to store charge so I suspect the solar panels on this one are faulty. The second wouldn't work at all, even when I removed the battery and just attached an external supply.
The up shot, I want to know where is the best place to tap into the circuit with an external power supply and bypass all the internal electronics and just power the LEDs. I can supply a picture or the circuit board if anyone can figure it out?
