Need help with choosing battery and fan for air conned shirt instructable Answered
Hi, I'm new to this site and pretty electronically noob and very sleep deprived so please bare with me haha. I was looking at completing this project- an airconned shirt https://www.google.com.au/amp/www.instructables.com/id/air-conditioned-shirt/%3famp_page=true . But I didn't know whether I am buying the right fan for the project. It is a 12v 92mm fan with "2 pin?" which I'm looking at on eBay. I'm not sure how the "2 pin" will affect the wiring- can I still follow the instructions on the page withh this specific fan? https://m.ebay.com.au/itm?itemId=322787438856 And yes 92cm is my preferred size, just a little smaller than the 100mm one on the instructable page. And also, comments state that I can save money by buying a 9v battery, but the fan will just run a little slower. My fan is 92mm and goes 3500rpm which (comparing the size and rpm of other fans in my local electronic store) is quite fast. I'm assuming that using the 9v battery it will just run a bit slower. Is this accurate or will it also ruin the battery/fan's life expectancy, or drain much faster etc? Comments have stated that the batteries used in the instructable would only last a very short time (and batteries being expensive) so I thought to use rechargeable ones. Its going to be a gift for someone who works outdoors in construction in summer heat so it should at least be able to go for 9 hours before recharging. Ps. Any ideas on how to make it cooler via an ice container or cube without wetting the whole setup? Thank you heaps in advance!
