> git clone --recurse-submodules [...]

Small improvement but it should get the clone and the submodules at the same time.

This should be _Kapton Tape_ https://croylek.com/pages/kapton-tape?srsltid=AfmBOoqVfkbfaW...

This, is how to enjoy your retirement. Hope we see lots of other fun projects like this from you John, a very enjoyable read. :)

This is a really simple "project" because someone else did all the work! I just had to install the thing and make some tiny code modifications for my taste.

I have been reluctantly holding off hoping they will come out with a dot matrix or epaper screen. Neither will probably ever happen but I can dream.

I absolutely loved my Pebble. It was so amazing in its own niche.

You do know that Pebble is back from the dead?

Admittedly my watch only gets 1/50 the battery life and doesn't pick up WWV. On the other hand, being able to redesign its face in Emacs and Illustrator and update it OTA makes up for a lot. So does not having to wear a molded polymer bracelet - those things are awful!

What's the process of adding sensors to the custom motherboard? Based on your watchface config it looks like you added accelerometer. I wonder what other sensors are easy to add. I'd love to have an hrm in mine

TSA: "Sir, are you wearing the terrorist watch?"

You: "no no, it's a modified terrorist watch, it now has more features!"

Very cool! What's the expected battery run time?
jgrahamc · 2h ago
See: https://www.crowdsupply.com/oddly-specific-objects/sensor-wa... Answer: 1 to 2 years. My previous watch from the original blog post is still running on the original battery.

Thank you, John.

Coincidentally, your web site https://jgc.org/ is truly a lovely example of https://news.ycombinator.com/item?id=44613625 which was just discussed today as well.

Love your behind the screens stuff!

Thanks! Glad you enjoy https://behind-the-screens.tv. Those videos were an enormous amount of work because of all the original research behind them. I do have one more I'd like to do about this film: https://www.rottentomatoes.com/m/defense_play_1987 One day perhaps!

Oh I don't doubt it! I was thinking how does such a busy man have time for this... but we always have time for passions and side projects :)

The airwolf one was funny, since it was a childhood favorite, and what a funny little typo they had there.

When watching the video I was thinking to myself, could this series have influenced my future interests in ways I didn't even know? Fun.

The key to doing things when you're very busy is to do them slowly and not drive yourself crazy with a deadline. When I did the ThinkPad 701c restoration it took me a year!
