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 via all my mobile devices, 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 withe different tutorials, I found failure.  Well, I finally figured it out and it works dammit!  I haven’t found a single source that...

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...

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. ...

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...

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....
