first time poster here. I am NOT an electrician and I have limited experience beyond basic wiring and home improvement, so please bear with me and feel free to over-explain. :)
If you've seen the series "Stranger Things", I'm planning to recreate the wall of letters w/corresponding Christmas lights for a Halloween display (reference: https://www.youtube.com/watch?v=MEZnX14qaUc).
I want to avoid using a lighting controller or anything like that due to the complexity and cost. The most straightforward solution I can think of is to get a strand of C9 LED bulbs and:
Cut the wires between each one.
Insert each 26 bulbs in the correct position but with the wires poking THROUGH the wall to the other side.
Extend the wires out and connect each positive and negative to it's own momentary switch.
Arrange the momentary switches on a surface like a homemade keyboard, labeled with the corresponding letter it controls.
Drape another (dead) wire across the bulbs on the front side of the wall to give the appearance that they are connected in a series, just for show.
Connected all the positives and negatives off the other end of the momentary switches together into one positive, one negative lead and connect that to a battery pack (2 AA batteries).
Assumptions (again, amateur here, please let me know if any of this is wrong):
- Using an inverter shouldn't be necessary for this application since the lights aren't going through a controller, it's a simple one-at-a-time light circuit w/a switch.
- 2 AA batteries should suffice, since the intended use is to light up one LED light at a time.
- I want to avoid plugging the lights into an outlet because I'm not comfortable with electrocuting myself, and it seems that LED's can run just fine off of a battery pack.
- More of a question, what is the most efficient way to merge 26 wires into one? Is there a piece of hardware that can like... crimp them together or something? I would rather not solder the whole thing.
What do think, will this work? Any suggestions and/or improvements? I am thankful for your expertise!
