  • Building an EC sensor.

  • The end goal for the Autodro is a complete monitoring system for under $10. This means that cheaper, simpler, less accurate sensors are needed. I've started with a simple EC sensor, and am hoping to design something around $1.So far, I've created a sensor...
  • muahaha, I cheated :)

  • So since the Teensy++ 2.0 bootloader is not available and I'm not feeling comfortable to learn all the bells and whistles of USB communications I was looking for other options. Googling "at90usb1287 arduino" I found this https://github.com/mattairtech/ArduinoCore-avr...
  • Reverse Engineering from Package Data

  • As you can see airodump-ng picked up the WiFi of the drone and also that it is running on channel 2. Next I recorded some packages. sudo airodump-ng -w JJRC_out -c 2 -bssid 10:A4:BE:2E:77:B5 wlan0mon While recording I simply used all the functions the...

  • What shall we wrap it all up in?

  • Any enclosure needs to be easy to access yet provide enough space to get all of our cables in and out without being too big. A tough challenge!---------- more ----------Once our technology solution is chosen, we have to mount it, cable it, make it all...
  • 20230214a -- Memory, cont.

  • Operating under the current assumption that RAM is 32 KiB banked at address 0000-7fff, with the first 256 bytes masked off by special function registers and internal SRAM, some other code sections of interest were found.  E.g.:ED00 loc_ED00: ED00...
  • ESPduino or Neopixels memory leak?

  • So after several days trying diffrenet approaches for communication beetween server and ESP8266 we finally got the last bit working on the project (have some back logging to do here at hackaday.io), MQTT over a ESP8266 to a Teensy 3.1. The resulting...
