Video Tutorial: Writing code onto Micropython Wemos D1 using Ampy

Last week we covered how to flash Micropython onto an ESP8266 (Wemos D1 Mini) but we had to type our code into the REPL by hand. That’s not terribly useful for a real world project, so this week we learn how to upload code and make it run on boot. We’ll be using a tool called Ampy, by Adafruit, since the Micropython world is a little immature.

Video Tutorial: Flashing Micropython on a Wemos D1 Mini

Welcome to Episodes #01 of the new Obviate.io video series where we’ll be flashing Micropython 1.9.3 onto a Wemos D1 Mini ( ESP8266 ) development board using Apple macOS.


Connecting a HID Prox Pro II RFID reader to Arduino

Arduino based RFID reader projects are a dime a dozen. It’s great and wonderful how plentiful and easy they are. Checking out Adafruit or Sparkfun one can find dozens of cheap components that are almost ready to go. The common factor is that they are all 13.56Mhz or Mifare compatible. Nominally this means cheap (And plentiful) components and fobs, but it also means that the systems aren’t compatible with most...

Quick First Look: Onion Omega 0

Quick First Look: Onion Omega

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...

So many IoT software platforms, where to begin? 0

So many IoT software platforms, where to begin?

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...
