Now that I have the proof of concept code running, it's time to modify the built in Arduino core library that handles OTA updates. The existing OTA library takes a binary object and an optional MD5 hash (to verify the upload), stores it in flash memory,...
I have software controlling the ESP8266 reading data from a DHT22 and sending it via MQTT to adafruit io. It's been working stably for over 24 hours. The code is on github at https://github.com/dgr-crenshaw/cyberHiveWiFi.git The powerManagement branch...
Its a pretty simple project. We use an ESP8266 to fetch time from an NTP server, and two Neopixel Rings ( 12 LED and 24 LEDs) to show minutes and hours.
According to https://nurdspace.nl/ESP8266#Ultra-low_power_technology in deep sleep the ESP8266 needs 33mW and ~ 660mW while transmitting, so if I can use a 95% duty cycle then the average might be 65mW. Very roughly...Again, very very roughly, because...
I'm pretty excited. The blimp flies and is as controllable as a large envelope full of helium in a drafty house can be ;) The blimp shown here is 24" diameter, 8" high. So what's different about this revision and why does it fly? Motors are spinning...
!!!! New version ESP8266 library will not work. At this moment only works old version. For example 2.4.2 Board manager ESP8266 - 2.4.2 1. Instal ESP8266 board into Arduino http://esp8266.github.io/Arduino/versions/2.0.0/do... 2.Enter your's Wifi router...
The project consists of an ESP8266 module which is programmed into MicroPython. For some reason, the Blynk library can not be loaded onto my module for RAM, so I had to use the Blynk API. The ESP8266 measures the temperature and humidity of the...
Project tool sponsorship: I was approached by a representative from Digitspace that offered to provide some tools in return for mentioning them in a project. I haven't done business with them as a normal customer. The name-brand items including...
From the last log it was determined the camera module needs at least an on off switch. "Since the ESP8266 cannot boot properly with the SD card and camera attached and powered, the power line for the camera must be default off, and switchable by...

Introduction WS2812b addressable RGB LEDs are devices widely used in lighting projects. They are found in the format of LED matrices and strips. LED strips, for example, are widely used in decorative lighting, luminaire construction and many other applications....
DataThe first step was to get the solar data from my Growatt 3000MTL inverter online into pvoutput.org, which is a great tool for uploading and comparing PV data. The method for getting the data into pvoutput is beyond the scope of this project (but...

I noticed a mistake I made in the EEPROM lifespan calculation, each value is only measured every 24 hours. If I use something like an offset counter that would have to get refresh every hour but if I just clear all the values after sending them to the...
