nimblemotors 23 Posted September 19, 2014 Share Posted September 19, 2014 One of those useless gadgets that people might like. Cold beer never gets any better when warmer, so looks to me this is only applicable to too-hot drinks. While a coaster would be nice, it seems to me with variations in the insulation of a cup, you can't really know the fluid temperature from measuring the cup. I think you need a new cup of tea. One powered by the hot liquid, and wireless connected to the internet and can scroll tweets on it... Yeah, that is it, a $50 internet cup of tea. Hope that helps.

In fact cold beer gets only worse while getting warm. That is why the coaster will notify you, when your beer reaches critical temperature (16 Quote Link to post Share on other sites
bluehash 1,581 Posted September 19, 2014 Share Posted September 19, 2014 PS The energy harvesting feature was only present on the first prototype, later I decided against it, since it will raise self costs and demand more complicated design;) Fixed. Thanks! Quote Link to post Share on other sites
igor 163 Posted September 21, 2014 Share Posted September 21, 2014 The thing with insulation could be a problem with some cups, like ones with very thick glass bottom. But most ceramic cups I measured have almost the same surface temperature as the liquid inside. In case you favourite cup has low thermal conductivity, you can set the "desired" temperature a bit lower as usual. How does it do with metal containers? (Aluminum, pewter, stainless steel, silver - Since they can have low emissivity). Maybe not the best to use with your silver tea service? Quote Link to post Share on other sites

But to be honest a metal cup users are pretty rare:) Quote Link to post Share on other sites
Citizen 7 Posted October 11, 2014 Author Share Posted October 11, 2014 Hi, PCB are here! looking awesome, as intended. Right now i need to buy some passive elements, solder paste and flux for BGA sensor. Here are some pictures of raw PCB. Sorry for lame quality , I photographed them using my webcam. I expect to assemble first prototype till the end of October. Small PCB, Main PCB , Bottom Main PCB with small one,Bottom view (Intended construction) Main PCB with Small one, Top view.
