I need to power 12V LED strips off of 6AA batteries that produce 9V. How can I get the extra 3V?
I plan on putting LEDs under the keys of both my Yamaha and Casio keyboards, The LEDs must me on strips so they dont interfear with the instruments playability. I have only been able to find LED strips that run on 12V and I dont want to have to add a second power source. How can I either change the resistance values on the LED strips or change the input voltage with out adding a new power supply?
