WeatherCloud – IoT

So, my son's been bugging me to get him some of those LED strips for his room.  You know the ones that you see on Amazon with the remote controls.  I couldn't just go with status quo, so instead with a little grit and some free time I got on the LED cloud bandwagon and built him something a big puffy cloud with lights - what every teen wants right? ;-) What is it? It's…

WIoT-2 Weather and Home Automation – Nextion with ESP8266/ESP32

This is a continuation from my first iteration of WIoT weather station.  What is WIoT-2?  I use it as a cloud-connected (IoT) info center of sorts.  It is a culmination of information my wife or I often look for either on our way out of the house, or when we come home.  It displays current/forecast weather, temp/humidity from outside the house (this), date, time, our local waste collection schedule, currency rates, the status of our garage…

Hot Tub: ESP8266 IoT Temp Monitor and NeoPixel Lighting

Finally got our free hot tub hooked up.   Well, not so "free".  Hot tubs are never free unless you have all the electrical and other bits already.  Anyway,  I wanted to add some remote temperature monitoring as well as jazz up the lighting a bit.   Given Winters can get pretty cold here in Canada, I wanted to get notified if the temp falls below a threshold as frozen pipes in a hot tub pretty…

WIoT: Weather Station & IoT Notifier

Update: Check out my latest version of this project WIoT-2. This is a project that I have been wanting to do for some time.  Since the marrying of IoT with microcontrollers, the world of cloud-connected devices has taken off.  I had a hard time naming this thing because its sort of a swiss army knife of IoT.  I keep coming up with new ideas as to what to connect to and control.    I've done other…

IoT Garage Door Monitor/Opener with Finger Print Scanner

I've got a lot of stuff in my garage, and having 3 kids (one of them being me!) with forgetful minds, the garage door is sometimes left open over night.  I don't really like that sinking feeling after waking up the next day to find the door was left open.  Between loosing valuables and critters that make a mess of garbage, I finally decided it's time to take a stance!  I have an IP Cam mounted inside the…

COVID-19 Daily Stats on a Nextion HMI using ESP8266

While Covid-19 picks a fight with humanity, keeping busy and your mind clear is important for all of us. In addition to getting out on hikes and biking with the family, what better way to pass the time than to built IoT stuff! Since I had a new 7" Nextion HMI screen sitting around just waiting for a project, and had some vacation time, I decided to buffer up my skills and get to work.…

BTBox – LEGO Power Functions Bluetooth Controller

I've been on a bit of a LEGO Technic/Mindstorms hiatus for a while - ok, it's been 7 years!   I have an I've been spending much of my hobby time making my own DIY projects / IoT stuff all while mastering Arduino.   That changed a few weeks back when I came across THIS.  I've been thinking of getting an RC crawler for some time, but it struck me that I have 95% of the…

Nextion TFT LCD – Why you need one!

I'll start this by stating that I don't work for iTead, and nor am I getting any sort of   I just really like this TFT LCD.  I stumbled upon the Nextion (which is a slick easy-to-use TFT LCD with a HMI editor) when they had their first crowdfunding campaign a year or so ago.   I ignored it as there was not a lot of documentation, and frankly, I really didn't understand the concept of…

ESP8266 – Lessons Learned

I've gotten enough ESP8266 projects under my belt to have a few lessons learned to share with you.  The ESP comes in many flavors.  One of my favorites is the NodeMCU.  I also like the Adafruit Huzzah WDT Reset Error: This error was the bane of my existence for quite some time.   When experiencing this, you typically see your sketch run and fail.  Using the Serial Monitor and carefully placed statements, you can usually…
