Here is peek at the initial control box for the bot. The ultimate goal for Lawnny is to make a good portion of it autonomous, but in the meantime I want to debug all the mechanicals without a lot of hassle, so the initial version of the control system...
There was one benefit to the unfortunate RUD (rapid unscheduled disassembly) of my motor controller in my last build log— it gave me an opportunity to spend some time on quality of life improvements. A fresh coat of paint Lawnny is an outdoor bot, so...
We've taken the first steps towards autonomy! Microcontroller and IP-Based Control As most of you know by now, the ultimate goal for Lawnny is to provide some amount of autonomous functionality. But even though I want to automate as much as possible...
For a daemon like p910nd, it's important to be able to send these to the system log facility as the process will be detached from the standard 3 file descriptors in operation. But we still want to be able to send messages to stderr for debugging purposes....
What is it ? The Input module doesn't technically needs to exist for a purely digital system, but as I plan to use this with analog devices (microphones and instruments) so I am designing it. This module is therefore separated in two specific part :...
After some more tries and checking the SD Cards twice, I tried using an older image of JetPack. Version 4.5.1 to be exact. This version installs correctly and after some minutes of install-duties it greeted me with a working LXDE desktop!"So, what's...
I found out that the OV5647 cameras I bought are not supported using the Jetson Nano. Or any Jetson for that matter. Although those cameras should be supported by the Raspberry Pi and it's Raspberry Pi OS, they are not supported out of the box on the...
Strictly speaking, this isn't part of the tile job. Since I was going to be opening up the walls, I planned to replace the tub/shower combo water controls. The current controls were probably the originals from when the house was built 30-40 years...
The big hacker day was upon us and the gears were in motion! Julia jumped into action during morning solo hacker time. She went to the Mission Fabric Outlet store to find our throne-worthy textiles, as well as coordinating with a participant...
I've started by laying out the five boards in Eagle 9.52. Boards are now being ordered through JLC. All parts have been ordered through Mouser and Digikey - however sourcing a small meter and solar panel that will match have been a bit of...
What you need are just: Lora Temperature/ Humidity/ Soil Moisture Sensor V3 Note: detect the soil moisture/air humidity/temperature and broadcast every 60 minutes. ESP32S3 based 4G LTE module LoRa Expansion Board This gateway is composed of ESP32S3 4G...

Insert two AAA batteries into the Lora Temperature/ Humidity/ Soil Moisture Sensor V3 battery compartment, burn the code into the ESP32S3 based 4G LTE module, and open the serial port, when ESP32S3 based 4G LTE module successfully...
