Damn this is cool. Someone made a Android mainboard replacement for the Q20. It fits perfectly inside the existing phone. Uses the same display but upgrades the camera and switches to USB C. It feels so good to hold blackberry again. The soft touch back feels amazing

We're really proud to show off the final design for Pebble Time 2*! It's quite a bit sleeker and imo more awesome looking than the original design for Core Time 2 we showed off in March. I hope you like it!

Also just because I usually tweet positive things - rest assured that just like any hardware project rushing towards production, there's tons of problems/issues/bugs/wild hacks etc that come up constantly. Generating a good list of wild stories to share in future

New Core Time 2 EVT power consumption numbers are looking really good. We have a zephyr-based 'hardware verification' (HWV) firmware that we use to qualify each new board. The current board is only sipping 108uA on average in our normal operation mode: - BLE connected - display on - IMU in tap mode

I read through all 3,100 applications for the new Pebble watch beta test (tho we could only accept ~200 right now, many more slots opening up soon to test the iOS/Android app + older Pebbles) You wrote 49,608 words about why you loved these watches. It means so much to me to read it all. Thank you!

I bought one of these e ink Kyocera KY-01L phones back in 2019 while in Tokyo (super hard to buy from NTT w/o Japanese), sold it on eBay after playing with it a bit (for a profit!) but grew sad that I didn't have it for my collection, so I rebought in $100. Very satisfied π
