Hey everyone!
Looking for some help on a power supply I'm trying to "mod". I have a old HP AC power adapter for 100-240VAC input @ 1A with a output of 32VDC @ 720mA or 16VDC @ 610mA. What I'm needing help with is that I need this to power 8 L.E.D's requiring 24VDC @ 11mA each. I was thinking of putting a resistor in the the 32V line to drop it down to 24VDC. Is there a better was of going about this? Please note that I'm doing this because I'm trying to build a project from scrap electronics and parts that are no longer being used anymore. I do have a limited but nice variety of capacitors and resistors. If necessary or not possible to achieve my goal, I suppose I can break down and buy some components or a power supply outright. Any advice would be much appreciated and thanks in advance for your time.
