  1. Thanks, guys, for all the advice and problem solving. I found a regulated 4.5v DC P/S. So.. I guess I'm all set. I'm going to order the components and hopefully I don't blow my apartment up. I'll come back if I run into any problems. If anyone's interested I can post some photos of the finished product. Thank you for your time!
  2. So.. you guys are saying I can use that power supply if it's regulated, but you honestly can't say for absolute sure that it's regulated. If I found a (for sure) regulated 4.5v I could use all of my other components I've selected and used in my diagram? Or would I just be better off with a 6v/1000mA and 120 ohm resistors?
  3. http://www.radioshack.com/product/index.jsp?productId=2049707 Going to buy the switch, jack, and power supply from radio shack and order the LEDs and resistors in bulk online.
  4. Alright, I took those grains of knowledge and sat all morning trying to figure this out. Decided to make this schematic for clarity. I'd like the make sure this would work before I buy the components. Did I do it right? I'll be using a DC jack and some kind of switch. Do these effect anything, would I have to reduce/increase resistance? Resistors will be 1/8th watt, 5%. Also, LEDs are 25mA and my selected P/S is 1600mA. Should the mAs match?
  5. I'm not sure if this is the right section, I'm sorry if it isn't. Hi. I'm not very good with electronics, this is my first project, and I'd really appreciate the help. It's basically going to be a weird hanging wall lamp (part of a piece of art). I'd like to power 24 3.4v LEDs in parallel on 120v AC current with an on/off switch. I've had no prior experience in electronics. I've googled around a lot, tried to learn as much as possible, but I still feel like I don't understand it. I figured running them off of a battery would drain it quickly. Is it even possible to power them on an AC current, or do I need some kind of DC converter? If someone could even draw me a schematic you'd have no idea how much I'd love you. I'll make you cookies. :D
