I finally got around to compiling up the ESP8266 firmware on windows, i'd previously setup an EC2 instance beforehand and got it compiling but not tested it.I used CHERTS setup here , which actually seemed to work as documented! amazing stuff :)http://www.esp8266.com/viewtopic.php?f=9&t=820Once...
When I started testing the EMG circuit of Mumai, I used a regular Arduino to digitize the analog signal that the circuit outputs. The Arduino ADC has a 10 bit resolution and a default input range of 5 V (if not using an external analog reference). That...
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...
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...
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...

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...

For the final log on the clock I will go into more detail on the software side. First I will briefly discuss the software architecture. Then I will explain the different display modes I developed so far. All code can be found on the GitHub repository...
I finally found the motivation today to replace the distance sensor on µBob. That involved de-soldering the ESP-12 module, replacing the sensor, bending the legs just right, replacing the power switch with a smaller one, and re-soldering the ESP-12....
It was the power supply all allong! Never ignore a first hunch. More testing on the connection revealed packet losses when the roomba was docked. I wasn't expecting I could simply ping the ESP8266, but apparently you can. Whenever the roomba docked,...
