LulzBot Mini 2 – Fan & Lighting Controller

I was so impressed with my Lulzbot Mini 1, that I decided to buy a Mini ; Holding true to my mantra, whenever I get a new toy, I can't leave well enough ;  So, I decided to re-create my original Mini 1 custom fan and lighting controller with some tweaks and enhancements for my new Mini ; 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…

3D Printed Diffused Case for NeoPixel Ring (12 LED)

Not being able to leave well enough alone, I'm toying with adding more show to my basement disco setup.  I decided to pick up a couple NeoPixel rings (12 LED version) and integrate them into the music-reactive mode.  These will be slotted in the open space at the bottom of the speakers near the sub port (see link below).   This was designed to fit for this NeoPixel Ring.  If you want to print some, download the…

3D Printed Banana Jack Inset Speaker Plate

In Nov 2018 I took on the adventure of finishing my own basement.  I'm now at the point where I'm wiring my AV system up and focused on the audio part.  When looking to find banana jack wall plates for the speaker connectors, I was surprised to see that most are flush mount with the banana jacks sticking out.  You can find some that are wall mounted, but they can be pricey and don't fit…

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…

3D Printer Raspberry Pi stand & case for OctoPrint Rig

Now that I'm done adding a TFT to my OctoPrint Pi rig, next step was to make a cradle mount for the LulzBot Mini.  I also integrated a power switch into the build.   The cradle is a remix from the Adafruit guide, while the shell are direct prints.  STL files for the remixed cradle are here.  The power switch holder is printed separately then glued using Goop (best glue ever!).

How To: TFT LCD with TouchUI on Raspberry Pi OctoPi Rig

I recently ventured into adding a " TFT to my LulzBot Mini.  I already have OctoPrint running, but there are times (usually during filament failure events) I need to directly control the printer (heat the filament, move axis motors etc).  After 3 painful days of messing around with different tutorials, I finally figured it out and it works dammit!  I haven't found a single source that has all steps in one place, so I decided to…

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…

3D Printed RC Hex to LEGO Hub Adapter

After building BluCrawler, I wanted to see what other possibilities there were with builds using RC crawler tires.  LEGO is not there yet with similar tires (closest are the Claas Xerion tires - but they are not crawler tires).  Anyway, it's challenging to mate a LEGO hub to an RC tire.  There are aftermarket adapters out there, but they are expensive, so I decided to design and print my own. You can download the STL file here.  Samples…

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…
