7 considerations to make when securing your Raspberry Pi

https://opensource.com/article/17/3/iot-security-raspberry-pi?sc_cid=7016000000127ECAAY  This article tries to get you thinking of security at an appropriate level for your Raspberry Pi and IoT projects without scaring you away from playing, experimenting, and innovating. It’s about striking a balance. Don’t let a challenge stop you from trying. Just be aware of the big picture for securing your projects.

Using a supercapacitor for power management and energy storage in IoT

http://www.edn.com/design/power-management/4458294/Using-a-supercapacitor-for-power-management-and-energy-storage-with-a-small-solar-cell–Part-1 The environment has abundant energy but little power. Energy harvesting can tap the environment’s “infinite” source of energy, and avoids the cost of wiring to mains power or replacing of batteries. This article will look at using small solar cells.  Depending on the light level, whether indoors or out, small solar cells may deliver

IoTuesday: Maximize Your WiFi!

https://www.sparkfun.com/news/2363 Interesting looking project: mount the antenna and ESP8266 Thing Dev Board onto a pan/tilt bracket with some servos. The ESP8266 code was updated to connect to a WiFi access point (AP) and begin sweeping up and down (about 70°) and left to right (about 180°). At 5° increments, the ESP8266 would take an RSSI reading. Finally the antenna automatically returns

Can you trust Linux-based Tizen OS?

http://www.infoworld.com/article/3187840/linux/can-you-trust-linux-based-tizen-os.html Yesterday there was a story about millions of Samsung IoT that are vulnerable to attacks due to zero-day security holes. “I have been extremely critical of IoT vendors ignoring the importance of updates and security, putting millions of users at risk. In the case of Samsung, what bothered me the most was that these devices

A quick look at the Ikea Trådfri lighting platform

https://mjg59.dreamwidth.org/47803.html Ikea recently launched their Trådfri smart lighting platform in the US. The idea of Ikea plus internet security together at last seems like a pretty terrible one, but having taken a look it’s surprisingly competent.   It’s running the Express Logic ThreadX RTOS, has no running services on any TCP ports and appears to listen on two

Realizing the IoT’s security imperative | EDN

But in the Internet of Things (IoT), where billions of devices are expected to be connected within the next decade, the sheer volume of devices isn’t expected to mitigate the security risk. In fact, given that many devices may share the same

Growing Ubuntu for cloud and IoT, rather than phone and convergence

https://insights.ubuntu.com/2017/04/05/growing-ubuntu-for-cloud-and-iot-rather-than-phone-and-convergence/ There are some important changes in Ubuntu Linux development: “I’m writing to let you know that we will end our investment in Unity8, the phone and convergence shell. We will shift our default Ubuntu desktop back to GNOME for Ubuntu 18.04 LTS.”
