Re: Introduction to LEDs and how to use LEDs
Does your book on The Do It Yourself LED Light Bulb (120 Volt Sockets) give links of where to purchased the components to build ?
The links that currently are listed in your instructions take you to Jameco. To buy the components from Jameco for a 40 LED Light bulb the costs are $45 + socket adapter and
$61 + socket adapter for the 60 bulb LED. This seems a little expensive to me. In a 120V socket at this cost I don't see how I would ever recover the cost of this bulb verses a few CFL's.
Thanks for your response, I originally found you on YouTube and have enjoyed watching your videos.

Ebay is the answer. I get most of my low priced parts online there. Browse around some and you can find some incredible deals.

Re: Introduction to LEDs and how to use LEDs
I need help with an LED lamp. I want it to cycle through colors and white with a small button. I'm not good at math or science so I need help figuring out the watts and rechargeable battery power and a lot more. If you could message me we could talk through a private message. The lamp will cycle through red yellow green blue white

If you are still there, I would be happy to help out out here on the forum. Private messages are not working for me anymore due to receiving too many emails right now. I have over 1,000 emails to read.
