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 workbench…  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...

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...

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 excuse… 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%...

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...

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 kickbacks…   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...

WIoT-2 Weather Station – Nextion TFT 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 mounted near our front door.  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 from , weather data from outside the house (from this), date, time, our local...

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...

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...

LulzBot Mini: Arduino Temp Monitor / Fan & LED Controller

I’m on a mission to reduce the amount of noise my LulzBot Mini 3D printer makes. I’ve already added a motor damper to the Y axis.  However, one thing that is consistently noisy is the case fan.   It’s on at > 70% nearly all the time.  In addition to this, the air vent fins in the side of the case amplifies the fan noise.  So, I decided to build my own fan controller....

DIY & Hobby Projects: Parts, Components & Tools Must Have’s

Most people who visit to this site are either DIY’ers, Makers, Hackers, or Robotics / RC enthusiast.  For the most part, we all do the same thing – we build or mod stuff for our projects or hobbies.  Over the years, experience and repetition has given we wisdom as to what works, what doesn’t, and key components that I want to have on hand.  I wanted to share a list of parts/components I have found useful...
