This shows the old circuit and the improved circuit that uses an NMOS FET in place of the bipolar transistors.

  • 1. Slow turn on.. slow turn off.. * wink wink.. nudge nudge.. know what I mean.. know what I mean.. * :3

    2. Your circuit is awesome! I've seen a Simpsons pinball redone with LED's, and it just wasn't the same. I love how you perfectly recreated, the exact effect, of a regular incandescent.

    3. Do you have the finished circuit, w/ parts list? Schematic, whatnot?

  • @kiyotewolf I don't really have a finalized schematic. Converted a machine and put it out on location, but it's been 6 months ago and I don't remember the values. I changed values for different areas to give a nice effect.

  • Awesome job there! I think you've really addressed a major gripe against the LEDs. I suppose the other one is that they are a little too "cold" in appearance. I recently converted my High Speed to LED lighting and love the brightness and color purity but don't care for the instant attack and decay. I think it is especially distracting when playing in a darkened room. Anyway, the trick now is to integrate your circuit into a LED bulb replacement, so that no machine modification is necessary.

  • can you show how you actually implemented this? Do you need a circuit for each light bulb?

  • How do I know if it will flicker when I change to LED? Have a Stern Stars 1978...

  • Simple and cool idea. This definitely takes away one of my major objections against LEDs.

    Now, this circuit needs to be build into the replacement LEDs.

  • yes

  • Fantastic! Plus TZ is my favorite table! DON'T TOUCH THE DOOR!

  • Looking good!

  • Absolut helpfull, THANK U.

    do more pls!!.

    =D
