ProjectAutomatic Litter Box - cloud solution in place
Progress on my automatic litter box: I fixed a mechanical issue in the gear system and moved recorded motor sequences from Arduino memory to cloud st…
ProjectBuilding a Laser Robot Arm to Get Frans Moving
I’m building a Raspberry Pi 5 powered robot arm with a camera, PCA9685 controlled servos and a laser pointer. The goal is to recognize my cats, track…
ProjectAutomatic Litter Box - Integration with database
Built the final Firebase proof of concept in PlatformIO with automatic authentication, Firestore storage, and cloud based motor replay. The next step…
ProjectAutomatic Litter Box – How to Store Movement Sequences
Researching how to implement Record & Replay for the litter box led me away from local storage and toward databases. I've started building a Firebase…
ProjectDual Control System for the Automatic Litter Box
Built a local control module for the automatic litter box using a KY 023 joystick and OLED display. The NEMA 23 motor can now be controlled both from…
ProjectAutomatic Litter Box -Hand-Soldered PCB — Wiring the System Together
At this stage of the project, things started to get messy. Multiple modules, loose wires, temporary connections… it worked — but it wasn’t sustainabl…
ProjectAutomatic Litter Box - Local Control Module — Joystick + OLED for NEMA 23
While building the automatic litter box, I realized something pretty quickly: Relying only on a web interface isn’t enough. I need direct, physical c…
ProjectAutomatic Litter Box - ESP8266 + TB6600 + NEMA 23 — First Working Control Loop
Successfully connected NodeMCU V3 with TB6600 and NEMA 23, achieving stable motor control over WiFi. Next step is moving position tracking from volat…
ProjectFrom Backdriving to Self-Locking — The Worm Gear Finally Works
After struggling with backdriving in my litter box design, I implemented a worm gear solution. Now the system holds position without power. A simple…
ProjectAutomatic Litter Box – Wormgear implementation
A heavy drum kept backdriving my NEMA 23 motor due to gravity. Instead of holding torque electronically, I turned to Reddit for advice. The solution?…
ProjectAutomatic Litter Box – Motor Tuning & Live Test Progress
Motor tuning session of the automatic litter box prototype. Tested drum rotation, torque behavior, and structural stability under movement. The mecha…
