If you are short on funds for a high tech security system, using a baby monitor can be a cheap alternative. I put the sending unit on the porch under the roof cover and the receiver just inside the front door. By adjusting the volume up I can even amplify sounds outside for easy listening. So this way I hear cars drive up, people walking by, and even wild animals nearby. My best buy for a baby monitor is garage sales for about 5 US dollars. Many newer baby monitors also have a video feed too, which I consider excellent for those without a peek hole in their door. With many having a dc input voltage, they can easily be rigged for off grid or RV applications also.

Dump a bag of ice into a dish pan of water and place in front of fan for a temporary way to cool off during extreme heat! Be sure to secure fan to avoid falling into the dish pan. Use common sense and safety precautions with electricity of course! Seems we often hear of deaths in summer heat due to heat exhaustion. Maybe this could save a life! This is cheaper for short term use than buying a air conditioner. As the summer heat is here, it is a good time to share this with your friends! Stay cool!
