It’s been a while since my last post! Every once and a while, I get a chance to sit down and work more on my power monitoring project. Previous versions of this project have been operational and collecting data for well on three years now, but I’ve wanted to clean …
This is actually work from a while ago – but I wanted to share this. I’ve been working on a new version of the Power Monitor PCB that uses an ESP8266 and Teensy 3.2. Here’s the board mocked up in SolidWorks CircuitWorks: And here’s the board in real life, with …
I recently came across this old aerospace senior design report I wrote, and thought it was pretty cool.
I recently installed a cool tool called Node-RED which is a neat visual coding tool for IoT-type devices. It uses node.js, and listens on port 1880. However, I wanted Node-RED to function over port 80, to avoid having to type a port as part of the URL. I struggled getting …
About a year ago, I made this motorcycle computer that mounts to the dash of my 2012 V-Strom 650. It controlled my heated jacket and my heated grips. I have access to a 3D printer at work, so I modeled some housings in Solidworks and printed them out. It’s awesome …
Along with the power monitoring project I’ve been working on, I’ve also developed a simple Internet-enabled screen. It uses another ESP8266, a few wires, and a 16×4 LCD display. The display used is one of the standard HD44780 compatible ones – so you can use the LiquidCrystal library, which is …
There are two chips that make up this board – the Teensy 3.2 and the ESP8266. The ESP8266 in this setup runs the AT firmware, which allows communication over serial using a published API. The API documentation is available here. To flash the ESP8266 with the AT firmware, Expressif (the manufacturer) has …
So, after a… while… I finally got around to getting this project together. Below, a quick picture of the completed and populated board. This required quite a bit of soldering, and I discovered a couple of problems during testing (hey, it’s supposed to be a learning experience!). The Teensy 3.2 and …
I got something in the mail today from Seeedstudio! And here they are: Here’s some close up shots of both sides: I’m very impressed with the quality and value. I only paid $26 for five of these boards! I’ll definitely be ordering from Seeedstudio again in the future. So …
A while ago, I stumbled upon this great organization: OpenEnergyMonitor. They’re doing a lot of things right! Anyway, they prompted me to attempt to create a derivative of their EmonShield TX. I loved the idea, but I wasn’t sold on the RF nature that needed a base station. Since it’s easy …
