This insturctable will show you how to make an empty pill bottle into a beacon using a few readily available electronic pieces, very little soldering expierence, and, of course, an empty pill bottle. Why would anyone want to use this? I thought about this one evening. I am a night owl in my home and am always the last to goto sleep. I try not to disturb the rest of my family the best I can. Sometimes though I need to remind myself to do something before I goto sleep like, put my clothes from the washing machine into the dryer. With this little device that takes took about 15 minutes to make, and is reusable, I can remind myself of something I need to do without waking my family with timers or alarms. This is a great way to recycle little clear or colored bottles and jars. It is pretty bright in the dark so you will see it when the light is turned out. There are many different little led bottle and jar lights on instructables. Check them out!
