+Erik Bročko No, not at all :) ! You really don't need to get the expensive ones as a hobbyist, there isn't exactly much the manufacturer can get wrong about making hot air. I got a ZD-939 for 70€ which works great (the one I use in the video), the 858D sells for as low as 40€. So it's just about as expensive as a decent normal soldering station.

Jeija Hmm... Thanks a lot! Well, with my limited student budget I'd like to get the best, most reliable and affordable one. That's why I'd like to ask, is a soldering station one-time investment? You know, different brands offer something else. Thanks yet again, I really appreciate it.
+Erik Bročko Being a student myself, I'm certainly not in the position to answer your question. The ZD-939 is my first and only hot air soldering station. It does the job well, but I can't compare it to other devices. I have heard good things about the 858D though (e.g. Dave from EEVBlog did a video on the Atten 858D). Generally, I don't think spending a lot of money on a hot air soldering station is a particularly good idea - it's not the best tool for the job anyways. Actually, the recommended way to build SMD PCBs is to use a reflow oven which are either DIY or priced ~250€, both are options I'm not really keen to try. So I'd say instead of buying an expensive hot air soldering station, your money may be better spent on other tools. By the way, the smartwatch is also designed to be affordable to build with a limited budget only (since I'm swabian and don't like to spend too much money ^^ ).
Hello, can you tell me at what temperature your hot air was (specifically when soldering the esp8266) and for how long you were heating it up? It didn't look like you preheated the chip either.
do u have any good advice to me. Because i want to start learning to make those kind of projects u showed in the video? in an other way i want lo learn how i can come into this "world" where u make small boards with alot of functions like the on you made.
Hi. Nice work! The pcb project are yours? do you have uploaded this to somewhere, i'd like to take a look. I'm trying to do something similar, but with some others components. tks
If you want some that are not already mounted on a PCB, you can get them from www.buydisplay.com Otherwise, there are many breadboard-friendly SSD1306 PCBs on ebay ;)
Thanks, would like to see more video on custom stuff. Trying to build a "pager / notification" display with the help of MQTT. I am not a electric engineer tho... :) I work with Back and Front-end on webb applications.
Yes, I was thinking about doing that at some point. Probably with a Sharp Memory LCD and maybe the Bosch BME680 once that gets released. I am also impressed by your Chronio smartwatch, especially the case design is really well done!
The ESP32 together with a memory display would make for a great smartwatch. The ESP32 should be able to receive notifications via BLE but nobody has done this yet. It seems like there are lots of features that Espressif has not implemented or documented yet.
You could technically download the KiCad board files or even the Gerber production files from github.com/Jeija/esp8266-smartwatch and order a PCB from Seeedstudio / OSHPark / ... It's all open source! You can't buy the PCB directly, I'm not selling them, I'm sorry.
Jeija, are you gifted? The things and the quantity of things you have done are incredible
That's amazing! You are the master of soldering. I still can't understand how did you fit the main ESP8266 chip onto the PCB on first try.
+Erik Bročko Lots of flux! The QFN package will then self-align on the pads.
But those hot-air soldering stations are soo expensive! :(

Excellent.... one of the best esp based projects i have ever seen...
+Jeija, that is some amazing soldering skills! Great job!
That is some serious soldering skills bro. Kudos
Words are not enough to define awesomeness of your project !!!
Very inspiring project!
I wonder how you get so much battery life out of this whole system!
Very nice Soldering. One question what do you use to clean all that flux off of the board once you are done soldering?
you have soldering skills man

tks
Sure, the author published it on Github: github.com/Jeija/esp8266-smartwatch
Boa sorte com o projeto! haha
Could you please provide the PCB description or link to buy the same?
Where did you get the SSD1306 OLED Display?
If you want some that are not already mounted on a PCB, you can get them from www.buydisplay.com
Otherwise, there are many breadboard-friendly SSD1306 PCBs on ebay ;)

Круто. На сколько хватает батареи?
sir which pcb card used this???
crazy skills!!
show muito louco excelente trabalho!!!!!!
amazing!
This is an awesome project. Impressive soldering skills!
Are you planning to build a second version based on the ESP32?
Yes, I was thinking about doing that at some point. Probably with a Sharp Memory LCD and maybe the Bosch BME680 once that gets released. I am also impressed by your Chronio smartwatch, especially the case design is really well done!

realy nice project
exellent proyecto
May I ask where can I get the pcb from. Thanks alot :)

Thanks alot!
hard core!
Hola bro. Yo quiero uno.☺🖒
Tell please how moch this coast (only components?
the page is www.solver-tech.com
no
U are project zorgo
