"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:

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… Download existing image The image can be downloaded from the Siemens support site (if you don’t have an account with Siemens you might have to sign up for a login first.

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. lsusb Should show something like this: Bus 002 Device 006: ID 04e2:1410 Exar Corp.

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.

Since there is now a supported Raspbian version without GUI and other unneeded add-ons available as Raspbian Lite the need to use other installers (with sometimes some downsides) is now not a necessity anymore. Below is a list of steps I like to perform before using them for any purpose as my Standard Operating Environment. Download Raspbian Lite Download link: https://www.raspberrypi.org/downloads/raspbian/ Write to SD Card dd bs=4M if=2016-05-27-raspbian-jessie-lite.img of=/dev/sdb Boot RPi Default login details are

Finally found some time playing with a RaspberryPi and an attached PiFace Interface board to control some garden pumps and potentially an Aquaponics setup in the near future. Requirements Raspberry Pi (Model B in my case, but any will do) PiFace Interface board (http://www.piface.org.uk) Base Raspian (Debian Wheezy) Install (I prefer the clean minimal install via https://githutb.com/hifi/raspbian-ua-netins). Configure the base system as per my previous base install. Install Apache & PHP sudo apt-get install apache2 php5 php5-dev php5-cli php5-mcrypt curl raspi-config

With the Internet of Things slowly becoming mainstream the potential uses of this technology can also be seen in the Education sector. This blogpost is the first installment of a series of posts that highlights practical examples that can be used in teaching and training. Part 1 – Environmental Noise Monitoring Some of the skills taught in these projects are: Environmental science Citizen science (collaborative data gathering) Measurement / sensing Data visualisation Data comparison With WideNoise users can monitor the noise levels around them using an App downloadable from Android Market or Apple AppStore.
