Hello All,
First let me introduce myself as a total-electronics-ignoramus; second as the inventor of an enhanced laptop computer AC adapter power cable.
We are in the developmental stages of refining the design prior to actual manufacturing. Due to marketing agendas and such I can not offer detail as to the special function of this cable; however it's the aesthetics, the oh-my goodness-what-a-cool-looking-product that humbly brings me here before you with my need for your expert knowledge and willingness to help the dumb guy. So here goes:
Laptop computers have various AC power adapter configurations with DC output power generally between 60 to 90 watts, 15V to 19.5V, 3 to 6 amps. These are the numbers you'll see on the transformer thingy. It looks to me like you could damn near start your car with these things. The burning question is: is it possible -- without too much expensive circuitry -- to place lets say six 3mm LEDs around the connector which plugs into the computer. (Macbooks and some new PC laptops have LED ring lights there)
Is there a simple way to implement this? Are there resisters that can deal with such a large discrepancy of power...as I know LEDs are miliamp creatures? Can we get by with a single resister? Or what? I'm clueless.
Any and all help, guidance and opinions will be welcome and greatly appreciated.
Thank you!
