Video Tutorial: Writing code onto Micropython Wemos D1 using Ampy
February 5, 2018
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.
Connecting a HID Prox Pro II RFID reader to Arduino
November 23, 2016
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 professional RFID badge systems. What if you want to hook up a “professional” grade system like a HID Prox-compatible reader? Turns out it isn’t that hard either.
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.
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.
RadioShack wants to get back to their DIY roots?
June 7, 2011
A week or so ago, RadioShack (yes, The Shack) posted a blog entry entitled “RadioShack & The DIY Community: You Talked, We’re Listening". The post is mostly a video from their brand manager which says they want to get back to their Do-It-Yourself roots. More importantly, they want their readers/customers to respond with what type of products RadioShack should be carrying to help this new DIY thing. Basically the post should been titled “We suck, please fix us”. Fortunately, Hack-A-Day rectified the situation for them with their own blog post, “Help RadioShack suck less".
Arduino Makes Halloween Better!
November 3, 2010
Halloween is my favorite holiday of the year. It’s a fun holiday where people get to mess around, have a good time… and family isn’t involved. For me, since about middle school, it’s been all about the decorating. I’ve done a lot of different decoration effects over the years, once I went as far as turning our 3 car garage into an haunted house once. This year wasn’t quite so elaborate, but it was greatly improved by the use of Arudino.
Arduino & USB = Dangerous
October 25, 2010
One of the many little tidbits of advice I found when reading up on Arduino was to protect your computer’s USB port. By that I mean buy a powered USB hub to plug the Arduino into. That way if you do something epicly stupid, you’d burn out a USB hub, instead of your computer’s USB ports. I thought that while this was a fair idea, I need not bother. After all, I’m a smart guy and I’m not going to be working with any serious amounts of power. Turns out… that suggestion was a much better idea than it seemed.
Review: Getting Started with Arduino (Book)
October 20, 2010
Since I’ve gotten onto my Arduino kick, I figured I should get some proper reading material on the subject. One of the first I saw was Getting Started with Arduino by Make: Magazine. Since “Getting Started” is exactly what I wanted and I rather like most of what Make does, I bought and read the book.
