My 9-year-old daughter likes to collect "jewels". Really just large pieces of glass cut into diamond shapes with lots of facets. She wants me to make her a display cabinet with lights under them so they glow.
I priced out a commercially made LED lights and controller and it would be over $200. Seems like a lot for 12 LED's and a wall wart.
I found the URL below which gives me almost all the information I want to know. The LED's I'm looking at are clear white 1800mcd and have a forward voltage of 3.5V @20mA. According to the calculator I would need a 50V transformer.
Instead of running them all in series, can I run a series parallel configuration? For example:
|-- 82R -- LED -- LED -- LED
|
|-- 82R -- LED -- LED -- LED
12V --|
|-- 82R -- LED -- LED -- LED
|
|-- 82R -- LED -- LED -- LED
Thanks for your help.
