Not sure, doubt it though. It's only running for a few seconds every 5 minutes. The rest of the time it's sleeping and oly using microamps of power. The temp sensor is sticking up above the board too, or I could replace it with a sensor on a long cable to see of it's any different t.
Yay! Finally have my 2 sensors working properly. I started having problems with my AA powered sensor after making my Li-Ion powered sensor. It just wasn't detecting the DS18B20 probe and I couldn't work out why.
I finally worked out it was the timing of the OneWire library with the AA sensor running at 4MHz. I had to adjust the timings of the library, cut them in half, and now it works. Yay :) The Li-Ion sensor is fine running at 8MHz due to the higher voltage so no problems with that.
Now time to modify my RPi code to show both sets of data.
Well that was more work that I was expecting. Thought I could just copy and pâté the code and change the ID to 1. Nope. SQL error. It's made me tidy up the code a bit and easier to add new data sets to it now.
It's pretty sweet. The only things I'd change are having tracks instead of wheels, and adding a salt/grit hoper. And a flame-thrower instead of a plow (devil)
(also, I'm a little ashamed about just how pleasing I found the neatness of the wiring on the distribution board :$ )
Yeah, I watched it again, and it's freaking cool but they don't even begin to explain how they built it. I have access to CNC lathes and tools and shit, but I'd never be able to just guess... But I have asked a friend of mine if he's up for a winter project, so who knows, maybe I'll build one. You could do commercial plowing with it or sell them! And I'm with you Koss, I'd put tracks on it. And I'd put a GPS receiver on it and automate every place I plowed. Show up, unload it wait for it to finish and move on... Profit!
