nice, but i dont think it will be a great idea for an indoor clock, GPS signal doesnt get indoors , maybe near windows, pls someone tell m rong

Hello dear friend! I want to create some clock. But with 7.5 inch display. But the U8g2lib dont work with my display. Can you help me with this problem?

https://www.waveshare.com/7.5inch-e-paper-hat.htm problem with this display.

It doesn't work with libraries U8g2lib. Perhaps you have a solution to the problem.

Great build! I have the exact same clock might will have to try this out. Mince still works but like yours the buttons are now starting to play up and the light to view the clock at night is extremely dim now. This project will give life back to my little old Micronta Quartz!

Nice project! I see that the display is a little slow to update so you probably wouldn't want to display seconds. I know that e-ink displays are normally pretty slow. I'm waiting to find one that updates a bit more quickly.

Hi,
Here is new case for this clock:

Nice update on your alarm clock blog series. Heat, but no smoke, is much better than instant smoke.

Your circuit has 4 resistors for each channel. 12 in total. Your board only has 9.

I think you've might have missed off the base resistor for the first transistor. That would explain the micro:bit being unhappy about driving it.

It's easily done when wiring a board like this. One method I used to use, with complicated prototypes, was to tick each component and each wire off on a copy of the schematic as they went onto the board.

Yes, transistors are your friend.

I had to use a transistor to boost the current of a RPi to drive a circuit. Simple solutions are always the best.

Hi Enrico,

Excellent, detailed post! Thank you for this, I'd not seen such comprehensive information on the micro:bit hardware - I did not realize the schematics were available. Also all the valuable detail about the test points and interfacing are awesome!

It's a really great platform - I purchased another one today, to explore it further and make more use of them, because it is very small and powerful. The fact that you're not exposing the LEDs provides some ideas. For some applications people could embed a micro:bit in equipment like you have, with just the USB exposed for external interfacing, and no-one would know that the system processor board was a micro:bit inside!

Looking good! Your update project is coming along nicely. You made some great choices of technology for the upgrade, while keeping the 'retro look' LED display. Did you think about a paper white LCD, as that might have been a nice look too?

Nice work Enrico,

Orange was definitely a popular colour in the 1970's (along with lime and brown). Good luck with your exciting build.

Hi Enrico,

Excellent project. That clock is in good hands, looking forward to seeing your results!

Interesting project. What a retro, high-tech look. I look forward to seeing your upgraded clock. (It was fun using Google translate to understand the button functions [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-aec1a98a-47cb-43f1-b550-05b52f3bd9d8/8105.contentimage_5F00_1.png:16:16])

Thanks for sharing.
