Hello, I usually just lurk around the forums as a first year engineering student, but I'm 27 years old. I have my bachelor's in Accounting, but I'm not very passionate about it...anyway, that's a whole different thread, but the point i'm getting across here is that my practical knowledge of electronics is nil. I'm still fighting against Physics and Calculus and haven't been able to touch the real meat of engineering. Here's the situation, my son wants to put a fan in the dog house to keep our dog cool in the afternoon when we're away. While it's cute and adorable, it's probably pretty dangerous for the dog and may be more of a nuisance than a help for the dog. However, as a little project for us, I was thinking that we could link together some really cheap solar panels on the roof of the doghouse and then maybe a series of Case Fans from NewEgg.com. My questions are: What are the materials required for this project? Where can I get some really cheap solar panels that would provide sufficient power to create a slight breeze in a dog house? Are there any dangers I should be looking out for? I know this is pretty cheesey, but my son is 4 1/2 and I'd like to get him interested in STEM and this seems like a really cheap and safe way to get him started.
