If you use an inductive charger and make returning the dice correctly to the charging station a part of the puzzle then it's win/win, the puzzle gets automatically reset and charges as well. Also worth bearing in mind a genuine Wemos board has a LDO voltage regulator with a drop out voltage of 250mV 3.7 to 3.3v is 400mV to OK but not a huge amount of headroom particularly as the 3.7v battery voltage will drop slightly under load/discharge, with clone boards your mileage may vary.
Completely hooked on these videos and planning to build my own escape room puzzles. Thinking of doing something in a briefcase since I have one of those sitting in the loft, or some kind of puzzle unlock box, if I can find a wooden box somewhere.
Wondering if it would be possible to program the microcontroller to recognise the faces of more complex shapes such as a dodecahedron, 12 faces, great project by the way
Wow that would be a good game to teach children how to add up and subtract numbers with two or more dice for the battery I would use a LifePo4 that is 3.2 volt at 2.24 Wh and you can connect that direct and being a AA size would fit into your box thanks for the video Bob in the UK
Happy New Year to you. Nice idea. I like that at least for this tech demo you chose the wooden boxes and didn't use a 3d printer. Apart from that, I can well imagine someone trying to throw/roll such a cube on the floor and screwing up the electonics. According to a test the TH-camr @GreatScott! made about the Wemos D1 Battery Charger a while ago, it seems that this shield lacks a proper over discharge protection and therefore has the potential to completely drain and / or damage your battery (Source: th-cam.com/video/aND0j2Y2IkM/w-d-xo.html). There are a few more quirks in regard to the max. charging current for example, but for more info on that, I'd like to refer you to his test. An alternative could be the TP4056 charging board in combination with a MT3608 DC / DC step up module in case you want to use rechargable batteries. A simple switch might be nice thing to have as well.
I made one a few months ago with a student! The purpose was dice for blind people and after it was thrown an mp3 player connected said what was the value.

Amazing work and crystal clear explaination has always !
Keep doing content like this !
Thanks

Have you seen the new Aqara Cube...could that be used to undertake similar tasks? Maybe with a large surround to give it better aesthetics...
Nicely done!
Thank you for your work! Could be possible make this with esp32 and ble comunication? Im trying but i cant connect three dices
Happy New Year to you.

A question: why not the arduino nano 33 iOT? it has the gyroscope and accelerometer on board and wifi.
Simply because I don't have one of those lying around in my parts drawer! :)
Brother i need this product plz guide

Smart dice are used by magicians but I didn't tell you that :-)
I came here after watching David Blaine on Joe Rogan. I thought it has to be a smart dice
Nice job
Where can we find Arduino file
Amazing as always! Next time, please, zoom more on code... too much white... and very small text
