Max7219 esp8266 esp32 LED Matrix NTP Clock in Shampoo Bottle Part 2
A longish video to go through the design process and the things I would change if I did it again.
I have added comments throughout the video highlighting poor design, parts that I changed during the assembly and things to watch out for if you make one.
I am not posting the STL files for the bottle parts but will post the STL files for the round to square matrix cover in the next video where i will cover in detail the code.
No that i have a working clock on my desk i will develop the code to do some much more like
1. Day, date and time.
2. Auto dimming at night
3. Wifi manager so you can easily connect it to a friends WIFI when you show it off :-)
4. Possibly a webpage to add the offset to GMT time.
5. may be a humidity and temp sensor.
