Regfigerated Drinking Flask
Well, we all hate those hot days, and anyway, here's my Peltier powered
portable drink cooler.
I started with a commercial can cooler from Aldi, and gutted it to make this.
I have cut a square shaped hole in the outer casing which has released the vaccum
because the peltier device has to make fairly direct contact to the inner casing
via an aluminuim extrusion.
As is, it doesn't work too well.
I suspect this is because I need insulation now that I have released the vaccum.
It has been suggested that I use Selleys Space Invader to fill the space
between the inner/outer casing because it supposedly has good thermo insulation properties.
