LulzBot Mini 2 – Fan & Lighting Controller

I was so impressed with my Lulzbot Mini 1, that I decided to buy a Mini 2.  Holding true to my mantra, whenever I get a new toy, I can't leave well enough alone.   So, I decided to re-create my original Mini 1 custom fan and lighting controller with some tweaks and enhancements for my new Mini 2.  Two key drivers were to a) reduce fan noise, and b) add lighting with control. How it…

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…

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.…

Basement Disco – NeoPixel Music Sync with MSGEQ7

I didn't have a lot of time in 2019 for projects as much of it was dedicated to finishing the basement. A year ago it was nothing more than concrete, storage and dustballs. Took the job on myself and did everything except hanging drywall and mudding (I hate that part). Best part of doing your own basement is you get to hack in all the bits and pieces necessary for future projects - like LED…

3D Print: Electronics Soldering 3rd Hand

After years using my reliable PanaVise, it was time to step it up with some extra help for soldering and electronics work.  I had this idea over a year ago, and pick-up some 3rd hand arms. They then sat on my   Now that the weather is cooling down, there's more time for hobbies.   That, and my eyes are not what they used to be, so this has become somewhat of a necessity.   Given MCUs…

USB Dial

This is another one of those "did it because I can" projects.  It's a USB dial that uses a Teensy Arduino unit at it's core and allows me to emulate my mouse.  I use TinkerCAD avidly to design my 3D printed models.   I wanted to have both this and my mouse at the same time.  The mouse would be used for some activities ( object selection/rotation/editing) while the dial would fill in to perform rotate/zoom in/out…

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…

BluCrawler – LEGO Rock Crawler with BTBox Bluetooth Controller

First I want to give a shout-out (and credit) to PunkTacoNYC as BluCrawler is based off his Chilli Crawler - this is his creation. I'm  just taking it down another path.     You can also find published instructions if you want to build it yourself.  For some time, I wanted to get an RC crawler, but they can be $$$.  When I came across PunkTacoNYC's Chilli Crawler, that was I figured I had 90% 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…

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…
