Just published a guide on how to set up the OpenWeedLocator software on the Pi.
It walks you through the installation, how to change configuration settings and use of the software.
Check it out here:

"if you don't have to work at getting the knowledge, it won't stick"
This is the single most important, yet most frequently ignored, fact about teaching and learning.
This is the single most important, yet most frequently ignored, fact about teaching and learning.
It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick.
Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.

Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

Sugar beet has not been grown in Australia for almost a century, but as the need for sustainable aviation fuels intensifies, the traditionally European crop could be making a paddock comeback.

The Nats have officially scrapped net zero as of Sunday, so I figured, why not call seven farmers under 40 to ask them what they think about the policy shift?

So exciting to finally get this in a cab and running.
It's been a long-held goal to get a proper OWL controller working that ran over a network and could scale, instead of just GPIO based.

Manage as many OWLs as your network can handle, remotely.

Differences between the third generation of high and low wheat similarity ryegrass are pretty clear through the camera lens.
So much more reflective leaf surface facing the camera, compared to the wheat-mimetic.
All 3 selections made by a wheat-ryegrass classification algorithm. No human input.

Finally got the MQTT-based operation of the OWL to some form of usefulness.
Only takes two lines to set the whole thing up:
git clone
bash owl_setup.sh
The interface lets you monitor, control and download data to check its quality.
