Maybe some people justifiably wonder what I actually do (if anything). :)

Well, a lot of things are stepping stones, but the river only gets wider! But I finally managed to publish this project, a digital clock. The details are on my blog.

For some strange reason, the forum software won't let me upload an image, but you can see it on the blog.

Pretty sweet.  I have some small nixie tubes that will become a clock one day..

Anyway, I will post your pics.

Beautiful! I love the font used!

How about using 4 units of 8x8 LED matrix with MAX7219 driver,  that will be a clean start without having to deal with the onboard AVR and cheaper too.

I have some 8x8/MAX7219 lying around, would love to built one if the code could be adapted.

Being in China, you can get all sort of parts cheaply from Taobao, your students would be happy to help on this.  :)

Hi ! Liked the clock.
I'd like to know, does it plays alarm ? How do you set time & Date.

I've made one same type & Adjust it with Bluetooth serial connection & want to add physical button.

Please help.

Funny coincidence. I just upgraded it last week, to fetch the time from an NTP time source using an ESP-01. Before that, it used a serial menu for settings, you would enter the time for example as 2018 1 17 6 33 00 (Y M D H M S). There is no alarm.
