  • Wow, there's *ALOT* of mislabeling if you go by the LilyGo specs. For starters, to upload software into the watch, you have to hold button 1, then tap reset, then release 1. Just holding button 1 will NOT put it into programming mode. The pinouts for the TFT lists Reset and DC twice, but only the top ones are correct (DC-12,RST-33). And for a watch, I can't find any reference to a Real-Time clock unit being built into the watch. Bit of an oversight. :/

  • 2:23 I had a square or rectangular shape there. I think he should have stuck with it. 3:59 I take it you meant 40,000 pixels. 4:37 Here's why I would have stuck with the rectangular or square shape. Although, this could have been solved by moving "start" to the left a little. Another case in point is where the t of "connect" was out of the frame.

  • it's also definitely worth pointing out the Bangle.js smart watch, it's not hardware open source but every single aspect of the soft/firmware can be hand written, and it's in JavaScript with the option for block programming, for those who aren't too good at programming. i actually just got myself one of them about a week ago and it's amazing

  • A few days ago I bought a 17 pack of old pebble and pebble steel watches. I don't like modern smart watches. I've had the versa 2. It is like the spiritual successor to the pebble watches, but development is tedious and unintuitive. It feels like a shallow immitation that can't get basic features down. Heart rate is nice, but all I want is a good battery life, music controls (which the versa makes you pair to another bluetooth SSID to do), and to show my notifications. That isn't a lot to ask, but there's so much garbage out there desparately trying to juggle features I don't want or need. is the only think keeping the pebble watches alive and I'm not ready to give up the (still superior for my use) smartwatch from a time before google bought fitbit who bought pebble.

  • I tried a smart watch ONCE. I do NOT understand what makes them so popular. I have literally no use for anything the smart watch provided and it was simple WAY too expensive for what I was actually using it for.... time. If you love smart watches, more power to you. I'd personally rather spend $200 aud on a nice G-Shock that will last me years instead of a smart watch.

  • Boo smart watches. Lame. Get a nice time piece and stop looking like a child. Use your phone for tech. Yes I'm an old man yelling at a cloud. but still. edit; ok fine, Paul gets a pass. thats a pretty cool idea. I'm still mad that most people buy useless smartwatches when a mechanical timepiece is becoming more affordable and usable by the day. There's loads of exciting stuff coming out and it looks spectacular. I'm almost curious if Paul could incorporate a proper automatic into this design to get the best of both worlds.
