10Hz is 100ms ... but anyhow, I agree, that is a heck of a log frequency for GPS tracking. And definitely yes on the KML format. It is not only used by Google Earth, but also supported by many other track/route editors. Then again, since it is based on XML it is prone to corruption when writing cont...

WRT clock sync, does the 8266 RTC always run off the RC? Can't be changed to run off the xtal when not in sleep mode? I think it can run on a dedicated 32kHz XTAL while not in sleep, but not on the hight speed CPU XTAL, like the esp32 does. Like you said most boards lack that 32kHz source, includin...

@MostlyHarmless: nice work! Now good luck getting a PR reviewed ;-) That is the part that I haven't figured out in this community yet. For example I have a PR open for the async-friendly improvements to the DHT driver, but so far it is more or less ignored. Do I have to open an issue in parallel to...

Great idea. But whats about ready to use products like https://www.adafruit.com/product/3133 Looks like engineers think alike ;) Note that that board isn't a ready to use NTP server. It is the GPS module and the DS3231 synced to it in one breakout board. You will still need something running an NTP...

...why are the RTC so inacurate?... It's hardware dependent. I believe the one on ESP8266 does not use a crystal oscillator, so it's wildly inaccurate. That on a Pyboard 1.x can be calibrated to within a couple of minutes a year. This is my understanding too. On the ESP8266 the RTC is completely dr...

In addition to the ntpclient project I am also researching in the direction of building a "cheap" local NTP server, based on the ESP32 chip and a few other components. One reason being that commercial, GPS based NTP servers still cost upwards of $300. That looks wrong to me. The last components I bo...

Inspired by another thread about ntptime and its limitations I have created a new module, ntpclient . This is work in progress. At this point it works reasonably well on ESP32 and to some degree on ESP8266. Both implementations very much benefit from a local NTP server, which is rather simple to set...

Maybe it makes sence to create a german sub forum here? Ich fänd das toll I do not agree - Ich stimme dem nicht zu. A fragmentation of the forum is of no benefit for anyone. Information will get lost. I second that. There will always be the an exception made when someone needs help but cannot expre...

Docker woks to some degree and I love putting all sorts of things into containers (FreeCAD, KiCAD, Prusa-Slic3r, you name it), but in the end I went a completely different route for MicroPython development. A dedicated Raspberry Pi 3. It runs CentOS 7 and has all the tool chains for ESP8266 and ESP3...

no encryption that cannot be deciphered

Apart from a one-time pad.

Well, in that case we go with lead-pipe decoding. You get someone who knows the cipher, drug them and pummel them with a lead pipe until they tell you the secret. Its ugly, but it works.
