News - IoTuesday: 5 Easy Ways to…

VLANs, routing, and proper firewalling (pfSense, Ubiquiti’s EdgeRouter or USG, most anything in the Microtik world) are the ways to go. Trouble is, not everybody knows how to properly set those types of things up. (Given that you brought it up I’m assuming you’re a fellow networking nerd; I know it’s second nature for myself, but that’s not any sort of assumption I’d want to cast on somebody else.) They also do cost a bit more than basic consumer-grade hardware (although the Ubiquiti EdgeRouter X is only $50), they also vastly out-perform them (1 Gbps routing, no big. The $100 EdgeRouter Lite can do 1 million packets per second too), are much more flexible in their configuration, and are updated routinely to boot. (Although you do need to apply it manually: ISPs don’t like it when their gear auto-updates.)
Something not mentioned in the article, but worth doing if your firewall can support it: Outbound filtering. You should be able to block outbound traffic from your IoT devices and only allow it to communicate with white-listed networks/hosts and on white-listed ports. There’s no reason most IoT devices should be talking on any port aside from 80, 443, or 53. (And even then 53 should only be to your internal DNS relay (router), so 80 and 443 to the outside world.) There’s always the possibility of other ports in the case of specialized services, but I would recommend blocking the port (with logging enabled), then watching the firewall logs to see where it’s trying to talk. White-list those destinations as you go until it’s working properly. (Even better if vendors just list where their devices want to communicate so you can build the rules ahead of time and not feeling like you are missing anything.)

Can confirm. My brother broke our parent’s dog with a laser pointer when she was about a year old. Now (9? years later) she still goes ballistic at any direct/bright light source, and will even chase shadows. If she knows you are about to handle a pan that usually causes reflections on the ceiling she’ll start getting excited…

I’d almost be willing to bet that 25 years from now, the “documentation/communications” technology will have changed so dramatically that your QR code, while a nice idea, will be useless
I think a combination isn’t a bad idea. Keep a live version on a wiki for ease of access and sharability, but then keep a printed archive in a 3-ring binder somewhere for hard-copy referencing later.

I wonder if you’d be able to pull the EL wire through after the bends are done by using the same trick teleco’s do when putting fiber into ducts: Compressed air. Basically you send air through the tubing and feed the EL wire in along the same path: The air creates a buffer along the walls that should help the wire navigate any turns it runs into.

I’d believe it. Thankfully I’ve never worked at such a place. (I’ve even gotten them all to purchase goods through SparkFun, although it took a while to find valid enough excuses to get it through. :-P )
I guess what I was getting after in the first place was that Digi-Key, for as big as they are, thinks SparkFun’s stuff is pretty cool and even carries quite the arrangement of their products. The reciprocal relationship between them is neat to see.
Just for kicks I started poking around and came across their “New Products” page.
