My homemade stir plate. Pretty pleased with the results. Didn't cost me 1 cent, so that makes it even better. Just thought I'd share...
Specs, for what its worth:
Phone Box, Old phone charger, Old PC fan, HDD magnet from same PC, hot glue gun replaced my need for any screws, washers, etc... I figured a bead of hot glue would space the fan enough from touching the top of the box. ( I was keen on having a flat clean surface.) And a free stir bar from a friend, yeah, I lucked out on that one.. I see some problems down the road with my box. It's not plastic so if it gets too wet I could have an issue. I need some type of coating.. maybe simple cling wrap would work? Anyway, hope you think it's cool too! Cheers
