We’re giving this idea away for free, so go and build one! A cup with a straw that has a heating element inside, so that your drink is heated on the way to your mouth - no more cold coffee! Plus, you would be able to finely tune the temperature. I don’t know about you, but if someone put this up on Kickstarter, I’d be the first to back it!
How's that for some DIY electronics?
