This video shows the build of a Simple Homemade Air Cooler using a Used Tropicana half gallon Juice carton.This desktop sized unit works very well and couldn’t be simpler to makeThis is made using made a “half gallon” (specifically 59oz./1.75L) juice carton, 80mm DC fan (blue-lit), 1.5″ PVC pipe coupler and a 3/8″ square wooden dowel.It holds about 2 ice-cube trays worth of ice at a time (and it has a built-in drain! so as ice melts you can drain the ice-water into a glass for a cold drink).
Thisonly took me 10 minutes to make it. cost about $8.50.This can be run using a 12v solar panel (2.4 watt or higher), a 12v battery or wall current (just use an ac to dc transformer that puts out 12vdc).

- How to build a Simple Homemade Bandsaw Mill from Old Car Wheels[the_ad id="6432"] This video shows the build of an really inexpensive homemade bandsaw mill out of old car wheels.One of the best things about this design is it’s simplicity of course, but it’s also made from salvaged and repurposed materials, which helps cut the cost of the sawmill down to an affordable level. Not everyone can afford $4000 to $5000 for a brand new portable sawmill. Building your own sawmill not only gives you that sense of satisfaction of doing it yourself, but it saves you money.Bottom line, it’s a tool you’ll use for years to come, and will more than pay for itself the first time you use it. Lumber isn’t cheap, and if you’ve got the natural resources and access to those resources, it makes the most sense to save money, time, and effort by using what you have available
