You need to get with the times. Those lights aren't going to cut it. The cup needs to send notifications to your phone and also an email to your computer. It should also send a notification to the wife alerting her that she needs to refill the cup. Now, it's $29.95, as seen on TV.
So many comical post even from down under. The phone thing is good if I can ever remember to turn my phone on or is there an app for that, but then again I'm still flip phoning, hate to give up the blinking coffee cup idea tho, those light emitting diodes are just awesome. The wife thing would've worked great 40 years ago, now not so good.
I was thinking of a design like this one, has great anti-tip geometry to it, but the add doesn't say how big it is, dont want to go over 12oz, might throw my coffee making mixture oof. Guess the thing to do is go up to the Mall, check it out, then go back home and order it online. https://www.thingsremembered.com/bl...sQ-YlAbommBBJqeFJOSpp02G2Jy06kWRCiBoCoBPw_wcB
Do a KickStart campaign, get folks to send money before you make anything. Fill their heads with empty promises. Wifi, bluetooth enabled coffee mug to sit on the shelf waiting for the next software update... perhaps you could get the recalled batteries from Samsung and use them to heat the coffee?
