How To: TFT LCD with TouchUI on Raspberry Pi OctoPi Rig
I recently ventured into adding a " TFT to my LulzBot ; 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…
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. …
