Storing Raspberry PI timelapse images using Linode Object Storage
"possum cam testing" (CC BY-NC-SA 2.0) by leogaggl 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.
Install S3CMD tools on RaspberryPi sudo apt install python3-pip sudo pip3 install s3cmd Configure Linode Raspberry Pi AWS-CLI s3cmd --configure The values:

Working with Siemens IoT2000 series from Linux
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…

Setting up MultiTech LoRaWAN gateway on Ubuntu
As the convener for the Adelaide community of The Things Network, I am frequently setting up Multitech Conduit Gateways. Depending on your PC or notebook hardware you might have some problems with the Exar USB-UART driver on Linux.
Here are the steps to getting this unit setup from an Ubuntu (should work for any other Linux distro) machine.

Microchip LoRaWAN Development Utility on Ubuntu
Having just wasted a few hours on getting this Java software running on Linux I am documenting this for future reference and hopefully saving other LoRa / TTN folks some time.
Prerequisites Install a Java JDK + JavaFX. This should work with the default OpenJDK 8 or 9 which comes as part of the Ubuntu repositories. I ended up installing Oracle JDK 8 as well as I thought the error might be related to OpenJDK.

GrovePi Zero - connecting your IoT sensors
I recently purchased a GrovePi Zero and expected this to be a reasonable straight forward way to connect Grove sensors to your Raspberry Pi, read sensor values via Python and pushing them upstream via MQTT. However the software side of things turns out anything but straight forward. Most of the suggestions on the Dexter Industries forum suggest to download some custom OS image – WTF? Hopefully this will save some people time to chase down the same rabbit holes….

Connecting your LoPy to The Things Network in Australia
EDIT [2018-06-05]: I have updated the code with the Firmware 1.18.+ releases. The code is available at our Growing Data Foundation Github.
These notes are to assist Australian IoT enthusiasts to get started in connecting a LoPy to The Things Network as it is unfortunately (not yet) straight forward to make them work with the current AU-915 TTN Channel plans. As the initiator of the local Adelaide Community of The Things Network I have been experimenting with a number of devices to connect sensors to #TTNADL.
