Hi. I did a forum search for Sugru and didn’t get a hit so I thought I’d mention here that I’ve found it to be a great ‘case’ for the watch. It’s kinda permanent, you’d need to cut it away if you want to disassemble it but I don’t plan to any time soon. 
I’m also working on my own firmware just for fun, I’ve only just started it but I’m really enjoying it. I’ve made a joke watch face which mimics the ps command. Here’s a video of how it looks:
I loved the ps command watch face do you mind sharing it. I am a terminal lover so it would be great to wear your watch face. I used sugru once it’s a great invention. The case looks really tough I liked that 
Cool, thanks. I realised after I’d added the Sugru that I forgot to make sure I can still hit the reset button. I haven’t needed it yet, maybe I can wedge a pin in there or something if/when I do.
I’m happy to share the watch face although it’s currently just a part of my custom firmware which is still very basic. I’ve uploaded it to GitHub just now, which is something I was going to do sooner or later.
You may need the reset button. Atmega32U4 is great because it has it’s USB hardware built in. However, this is also a dis-advantage. When the firmware running inside, mess with the internal timers, USB hardware stops working. Reset button comes into play when that happens:)
Thank you for sharing the code 
Hey there, I thought I’d mention I’ve updated my watch with a new watch face. Here’s the Giphy gif link. It’s a jittery, scribbly looking thing.
I was using SSD1306Ascii for the other watch face since it was all text, but I don’t need the text rendering any more, so I looked for a smaller, leaner OLED library. Didn’t quite find what I needed (either bloat or bugs or both) so I wrote my own. Yet another SSD1306 library, but mine is about as small as it gets – no other device support, no graphics drawing primitives or anything. I’ve updated the Github repo.
And yeah, over the last few days I did need the reset button. With a bunch of practice I was able to hit it semi-reliably with a pin but it’s a pain. I feel like it’s in an awkward spot as it is, under the display there, but I guess if you put it on the back it’d be under the battery… there isn’t a particularly good spot to put it.
Okay, this becomes my favourite watch face of the month:) I am surprised that you wrote your own library:) What do you do as a job:) Your firmware uses %45 of the total program space that is very good:) Any future improvements?
@toby, today we have tried the watch face with @mtulu at the office.
Incredible job, Really cool graphics. I am always amazed by the new ideas that use watchX. Keep up the good work.
Thanks guys, I’m glad you like it. I’m really only just getting started. Planning to add BLE and MPU support, etc. – it’s a learning experience, hence why I’m happy to write my own code rather than just borrow from other firmware.
I realised today that it’s sampling the battery level too often (i.e., every animated frame) which is a bit crap, so I pushed a minor update to github. Next step will be to add a proper event scheduler rather than just delay()s and powerDown().
Hello Dear Toby:) How is your progress going. I am really looking forward to the next version of the firmware:)
Hello Mustafa! I’m afraid I haven’t spent much time on my watch lately, other than to fix a couple of bugs. I have been distracted by other goings-on but I hope to do some more work on it soon.
Great! Looking forward for the new version:)
