It's cable I've ripped out of an old PSU. Too chunky, need to find something smaller and easier to use.
I've an idea. You could try some spare pieces of CAT6 cable you may have lying around...
Will Cat5 do? Don't think I have any Cat6.
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.
For a few hours and now it's stopped working again. Grr. Need some more 18650 holders.
Here's an arduino project for you, Ken.
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 :$ )
