Not sure about other things but I like my pinecil so far. It is cheap, well built, works as advertised.

The Pinecil is the best soldering iron under $150, and it costs $20. I absolutely love it, I bought four.

I have never seen it for $20, more like $65:

Still good, but not quite that cheap.

The last one I bought (two months ago) was $25.99. $11.99 shipping, sadly.

I've been burned twice by Line. First with the PineBook Pro, spent months trying to get it in an acceptable spot with Debian by piecing together reddit posts, obscure forums, kernel mailing lists... Complete disaster. Then I tried the PineTime, this one was less of a mess trying to get it to work, but only because it has been effectively abandoned--waspos is dead, infinitime is getting there, and neither offer an eas…

>waspos is dead, infinitime is getting there

I'll grant you than waspos hasn't seen much activity in the last few months, but I'm curious what data you're basing your claim of infinitime "getting there". Releases still come about as often as they always have, and looking at the github activity directly refutes your claim.

What are you talking about? They're extremely clear when some hardware is aimed at developers and code is not yet ready for users, which for example is the case of the PineNote. https://pine64.com/product/pinenote-developer-edition/

Their hardware is aimed at developers and yet none of their products has even a decent developing environment? It's not aimed at developers, it's aimed at hackers

Haven't used the PineTime but for the PinePhone/PinePhone Pro the development experience is the best I have ever had on mobile.

It seems you missed Librem 5 then.

That's the EU price, right? They're $27 in the US: https://pine64.com/product-category/pinetime-smartwatch/.

From looking at the slides it looks like a really impressive project. But I can't help but feel like very low cost full-blown Linux devices are right around the corner. Ex: https://www.cnx-software.com/2024/02/08/licheerv-nano-low-co... If you can run full blown Debian on your wrist soon, why bother with this severely restricted device that are a pain in the ass to develop for?

Battery size and battery time are the primary constraints for a wrist watch. The power efficiency of a SoC that runs full blown Debian, as well as Debian itself is much worse than the NRF52 used in PineTime. Without doing calculations, I would estimate 10-100x. With corresponding increase in battery size or decrease in battery time. That said, I believe there are smart watches that run Android on Linux, and they do manage 1 day of use.

A better development experience would be to use MicroPython. That will require a microcontroller with more RAM and FLASH space, but could equally power efficient. When using the LVGL UI library, and decent drivers for the peripherals on the device, and a live she'll connection, it is a very productive and pleasant developer experience.

The TTGO Watch S3 is an example of such hardware based on ESP32-S3 chip. Hardware is nice and cheap, but they have a hodgepodge custom SDK with forked MicroPython :/

Bought a PineTime for $27 plus shipping. Wear it while running to measure my BPM. I send the BPM to the Gadgetbridge Android app via Bluetooth. Upgraded Infinitime via Bluetooth. Have not messed around with the OS code yet. Have been happy so far.

Does it do sleep tracking? How long does the battery last? I still daily drive a Pebble 2HR with over a week of battery life but am looking for a replacement compatible with Gadgetbridge, and there really aren't any that can track sleep in a way Gadgetbridge can understand...

If I do cardio exercise for an hour and am measuring my BPM the whole time, a little less than 20% of the battery is drained. They changed the BPM algorithm in the latest Infinitime update, not sure what the battery hit was in the old one.

I turned off Bluetooth and put the watch on the shelf five days ago, the battery drained maybe 14% over that time. I mainly use the watch to measure my BPM, but it can do other things (measure steps walked, get notifications from an Android phone, stopwatch, tell time of course, a somewhat weak flashlight app, it even has games like 2048 and Pong).

On Android there is a Sleep as Android app, which I have never used, which says it integrates with PineTime. Reading what people on the net say, some have been happy with it, some have encountered problems. I have never tried to get sleep readings on Gadgetbridge and don't see any talk about Pinetime and Gadgetbridge for sleep on the net. I know someone who has a Fitbit where the sleep measurement from watch to Fitbit app is very extensive, and even tries to estimate when someone is in REM sleep and such - Pinetime doesn't have anything like this yet.

To me it's a $27 (plus shipping) hackable watch that does the main thing I want it to, measure BPM. As people code for it, it will probably get more capabilities - someone already improved how it measures BPM in the latest version of Infinitime by doing some fast fourier transforms and the like. Some of the more expensive watches seem to have more capabilities, but I like it for my purposes.

I agree with sibling comments that battery life would be the real issue here, but I was astonished to see the $9 price tag on this. Incredible.
