    Fade-in Background LED Lights for TV

    Please take a screenshot and paste it here. There are many pictures and two videos. All seem fine to me.

    I checked the pictures and according to my computer and tablet they seem normal. Maybe you mean the two videos? Those are dark on purpose.

  • RGB LED constant current fade effect with transistors

    Hi, sure go ahead if you do not intend to do something illegal with the site.

    Automatic mailbox light

    if you make it in a nice box there would not be a problem. I was thinking about adding a IR proximity sensor that would light a led when the distance to the box bottom changes (there is mail in the box)

    Thanks! Simplicity can be defined in many ways. You defined it as a small and easy circuit. In this project I defined it as easy maintenance. A light in the mailbox is something that is helping you, but you do not notice it until it does not work. When that happens you might not have spare parts available. For that reason only one battery is suifficient to get it runing again. And that battery does not have to fresh out of the box. It can be slightly used and it will still light the mailbox for many mail checks.The boost converter is a super important component. It allows the battery voltage to be anything between 0,2 - 5V. This also means that the bateries will get sucked totally dry before needing to change them.In your circuit the only color led you can use is red or green. Blue, wh...see more »Thanks!

This also means that the bateries will get sucked totally dry before needing to change them.In your circuit the only color led you can use is red or green. Blue, white, UV... has over 3V forward voltage so they would be very dim or totally off. If you would choose red leds, the forward voltage is 2,2V. This means that when it would be time to change batteries, you would have a ton of energy still left in the batteries = bad design of the system.About the fading, I agree with you. It is over engineering. It would have been such an easy circuit so I had to put something more in it ;).

  • RGB LED constant current fade effect with transistors

    My limiter uses 5 components. Transistor, 2 diodes and 2 resistors. The one you are referring to uses 4 components: transistor, FET and 2 resistors. Too complicated?The same ammount of different components, mine has just one more + is less expensive.

    Yes of course. The whole point with the current limiting circuit is to allow a maximum of 60mA to pass through the LED:s. Otherwise the leds will eventually burn.Your circuit sounds nice! I hope you still have it left somewhere in your closet.
