I'm doing a craft project and would like to install two red LEDs that are powered by a battery pack with an on/off switch. I would love your opinion-advice on what to buy and where to buy it.
- Handiness level: good to very good. Specialized tool ownership: novice. I have used soldering irons and been competent with them, but I've not had one for years and have had no need for it since. I'd really rather not buy one just to complete this project, so anything I can assemble with twisted wire and black electrical tape is a winner.
- LEDs: red. Their size doesn't really matter - in my mind I'm thinking of the LEDs the size of the ones used in throwies
but really, whatever works best.
- I would prefer LEDs be diffused with more of an omnidirectional output as opposed to clear. It will be almost impossible to mount them so that they're pointing to the exact same place and I'm worried about the viewer seeing them as one brighter than the other based on their viewing position. Strength over distance is not as important as visual consistency.
- I need two feet of wire between the battery pack with on/off switch and the LEDs themselves.
- These will need to stay lit for at least 4-5 hours. I don't know if I can just use a few CR batteries or if I'm going to need a 4-AA box, or what. The instructable on throwies says they'll last a week off of a CR2032. I'm thinking I'd prefer a little black box for some AAs with an on/off switch built in, just so there's less for me to tape and assemble. Ease of battery replacement is important. I don't want to have to fight tape to stick in another CR or use a screwdriver to open a plastic box to put in another 9v.
- Durability: short-term. Doesn't have to last for years, only days.
- Buying all of this in one place would be great. If you think my local RadioShack has everything I need, then awesome. I'd love recommendations for particular part numbers to seek out so that I can call them and ask in advance of arrival. If RS is out, then where would you go to buy such things? I have a little time, so buying online is fine.
