I think this is the appropriate forum... Maybe I'll post this in the lighting forum if I don't get a response here.
I'm working on converting an old record player into a clock and adding some LEDs. I've done this once before, but the record player I used before was in better condition than the one I have now. And on that one I just tapped into the existing wiring to power the LEDs. This was my end result:
ALSO! If you know how to make the hands of the clock light up I'd love to hear it!
So moving on, on this second record player, I used a DMM on various locations to try and find a good power source for the LEDs. However, the highest voltage I can find is about 2.6, which I don't think is enough. Also, nothing will work on the record player: the turn table won't turn and the motorized arm doesn't work. Unlike my previous project, my plan this time is to bypass the existing wiring and put in my own. And this is where I need some help.
I don't want to mess with batteries to power the LEDs. I'd like to be able to plug this thing into the wall, flip a switch, and have the LEDs turn on. So if I'm understanding things correctly, I'll need a transformer to make this happen? So I'm thinking it would go like this: power cord to transformer, then transformer to LEDs/resistors. Is that right? I keep reading about transformers and wattage and then I get more confused.
This is the transformer I'm thinking of getting.
This is the switch I'm thinking of getting.
These are the LEDs I already have. I plan on using 24 of them for this project.
These are the resistors I already have.
I used the calculator on led.linear1.org to get this and plan on wiring the LEDs this way:
I basically don't know for sure if I can wire the LEDs safely this way. Can a very wise member with vast knowledge and great experience help me out on this please? Also, can I use the transformer and dimming switch I picked out?
