Quick First Look: Onion Omega
October 30, 2015
Back in April I backed a Kickstarter for the Onion Omega. It’s another new hardware development platform centered around the Internet Of Things. While I’ve already got Raspberry Pi and Arduino aplenty, the Omega caught my eye as being a really nice blend of both worlds. Arduino is actually very hard to use for standalone IoT because it’s not fast enough to support SSL; it also requires you program in C. Raspberry PI is designed to be a full computer; it isn’t “cheap” ($40 times a number of devices adds up in cost) and is battery intensive (comparatively). The Onion Omega picks up a lot of strengths from both sides of the spectrum as it’s a full Linux machine (meaning I can write in NodeJS), fast enough to support SSL, tiny, AND has built-in WiFi.
Electricity as a shower (Understanding Volts and Amps)

Normally electricity and water don’t mix, however today we’re just talking analogies. When working with electronics, it’s very common to see questions along the lines of “My project requires X volts, is it okay to use Y power source” or “My Raspberry Pi requires 1 amp, will a 2 amp power supply burn it out?". If you don’t know electricity, this makes perfect sense to ask. Rather than answer specific questions, how about an analogy?
So many IoT software platforms, where to begin?
August 13, 2015
When you talk about the Internet Of Things, there are two major types of platforms. The first is hardware and while it’s growing, it’s fairly easy. The big hardware platforms are Arduino, Raspberry Pi, Particle, Intel (Edison), and MediaTek. There are, of course, many more, but that covers a majority of the hardware. However, since the hardware tends to be small, low power, and “dumb”, the IoT revolution will truly be built on software. As such that brings us to our second platform list, which is much bigger and much more confusing.
