One of the tasks Google Earth Pro is really useful is getting a quick idea of the viewshed from a specific location. This is particularly useful for planning solar installations or other infrastructure projects such as LoRaWAN gateway deployments.
Whilst the tool is quite powerful, it has a very limited viewshed (roughly 5km) and this is not really useful when looking at gateway deployments that in flat regions of Australia easily can reach 25km+. Also it is not at all obvious how to modify the radius of the viewshed since that has not been a feature in the GUI and it is not documented at all.
One common task for my Raspberry Pi Zero with (infrared) Camera is to do still image capture in regular intervals and upload the images for storage and post-processing. A simple way to achieve this with standard software tools available in the Raspberry Pi OS repositories is to use the S3 CLI tools and a simple bash script run by a scheduled cron job.
The Siemens IoT2000 series has been a very interesting development from Siemens and it’s really encouraging to see the use of Open Source in the Automation sector definitely on the increase. And that can only be a good thing for developer productivity. Seeing a different IDE for each manufacturer of a PLC invokes some nasty memories of last century web-application development…
Siemens Simatic IoT2000Unfortunately, all the documentation for these units still assumes a Windows PC. And since I have not really been using a physical Windows machine for 10+ years now, that is really slowing things down. For the last few I didn’t really have to fall back to a VM, largely due to the fact that in web-development nobody cares about OS any longer. But I have a feeling that shifting my focus to the IIoT space this VM will get a bit more useful as some of these manufacturers don’t even bother with anything but Windows and are challenged enough to keep up with Windows upgrades.
