Hi everyone, newbie here! Trying to find a power supply for LED backlight strips off of an LCD television. I've stripped it down but can't see it marked clearly anywhere. There are 2 strips with 6 LEDs on each. Printed on the light strips is the following: GJ-2k17 CSP-315 Pitch 109 (614x12) -v2.1 O1T38-1 RJ94V-0 E349376 HY-AI YK 1825 Attached are photos Cheers for any help!
Hello, I am trying to modify an FM radio such that it blinks an LED according to the data I transmit from my FM transmitter. I am following the circuit attached below. Is it possible to connect LED to speaker terminals to obtain such result? or any other suggestions? Thanks
I want to charge a LiPo battery via the ballance plugs. So it's a ballanced charge, and I don't run into any problems, day in and day out.The light can be very small, but I want it to be bright. So even using a couple LEDs would make a really nice and bright mailbox light.I want the light to last all night long. So that means I need to know the current draw of the LEDs to the capacity of the LiPo batteries.etc.I need help on this. I need help with the fact how to use an Op Amp to shut the light off when it's daylight out.. or a specific amount of light is sensed.Light Sensed : Start charging, and turn off the LED lights.Light Sensed : Set the Op Amp to detect 4.2vdc. When it does, shut down the charging, &LED's stay off until darkness is detected.That's my idea of a mailbox light, with very long battery life, and high current solar charging abilities.Can anyone help me with this kind of circuit? Here is where my LED come from http://www.kynix.com/Search/led.html
