  1. As part of my efforts in STEM outreach, I recently ran a workshop for Year 9 and 10 IT students at a local high school. I wanted to present something that would be interesting and different from what they would normally have from their school classes so I settled on doing a simple IoT demonstration involving Raspberry Pi, Sense-HAT, and Node-RED. The Raspberry Pi is a great way to introduce students to computing and electronics engineering. The students I was presenting to had little or no programming experience so a visual system such as Node-RED enabled them to program simple tasks. Within
  2. Another DDOS attack reportedly from IOT devices: http://www.news.com.au/technology/online/hacking/common-household-connected-devices-manipulated-by-malware-for-attack-on-worlds-biggest-websites/news-story/2170820dc7a293f8ff1d31dc89f13b64 Very apt that tomorrow's webinar is on IOT security.
  3. Has something changed with the webinar registration? I used to be able to register for the webinars for free as an IEEE member. But when I tried to register for the last webinar, I was asked for credit card details for a $30 charge. I noticed that the charging information on the registration site is inconsistent. On the left side, it says that registration for EA/IET/IEEE members is free. On the right side, it says it is free for EA/IET members, and $30 for other society members. I sent an email to memberservices@engineersaustralia.org.au last week asking about this but have not received
  4. IMHO... IOT is a user of technologies rather than a being a technology itself so there is no single set of standards governing IOT. Device developers choose technologies based on the constraints they operate under. There are two broad categories of standards in which to make choices: network access (comprising the physical and data-link layers) and application protocol. A lot of standards that have been mentioned previously have to do with network access (Bluetooth, Zigbee, wifi, etc). These standards can be used by IOT but were not designed specifically for IOT. At the application layer,
  5. I would have thought that driverless trains would be an ideal starting point for driverless vehicles in general. There are several advantages to trains: 1. They run on well defined tracks 2. There are fewer trains in a rail network than cars in the road network which simplifies the infrastructure/vehicle and inter-vehicle communications 3. There is already a standard for rail network communications (GSM-R) which could be extended to handle more situations 4. They don't have to contend with pedestrians
