I've added a batch of new divider layouts across my storage box system — regular, flat, tall, triple and extended series — based on your feedback. I've updated documentation and uploads; downloads are available on the new platform. Please take a look and read the full post for details and download links.

I published a detailed update to my stackable storage boxes project that adds new rail grid series, larger sizes up to 9×9, and improved catalogues. I outline design reasoning, alternative part-number placement, image and archive changes. If this sounds useful, please read the full post for downloads and printing notes.

I recently updated my storage-boxes system to include split boxes so you can print larger containers or use small printer beds. I tested glued joints with PLA and PETG and added 12 new STL parts. Read the full post to see part numbers, joining tips, and where to download them.

I walk through the sensor board I designed for the pet feeder, explaining the position sensor, four fill sensors, and why component choices (like the 100kΩ resistor) matter. I keep the design simple and practical — read the full post for schematics, measurements, and ordering details.

I solved stray light hitting my pet-feeder's fill sensors by filling 3D-printed slots with black, low-viscosity epoxy. Using a syringe I achieved a nearly flush, cleanable surface that keeps measurements accurate. Read the full post for materials, step-by-step photos, and a short demo video if you'd like to try it.

I ran into unexpected problems testing the fill-sensor panel: light was travelling through the printed turntable and confusing one sensor. I walk through how I diagnosed the issue, which fixes failed, and two practical approaches I’m testing — read on for the full troubleshooting and print updates.

I updated my pet-feeder's drive with a TMC2209 SilentStepStick and a 17HS19 stepper to get near‑silent operation and run from 5V. I built a simple Pico-based controller, adjusted gearing for speed, and tested sensors. Read the full update for photos, choices and test notes.

I've assembled the new input boards for the pet feeder and I'm testing the sensors—940nm IR LEDs paired with phototransistors. I share photos of the board top and underside, the turntable mounting, and revision notes. Please read on if you'd like to see the test results and next steps.

I've updated the flat boxes set with a refined wall profile (revision B) and added five new boxes, including a large 2×4 and four grid variants. I show corner comparisons and note existing customers received files. If this is useful, please check the full project details on the project page.

I've finished testing a new set of tall storage boxes designed for 3D printing. They're stackable with my flat and regular boxes, with reinforced walls and improved corners for cleaner prints. Download the free sample set or read the project page and catalog for full designs.

I finally put the fan controller into a cheap plastic case, drilled holes, mounted the Arduino with spacers, and aligned the display using double-sided tape. I cut the panel with a Dremel and it fit better than I expected — read on for photos and simple tips.

I tested a prototype of my Cat Protector and then built the finished device. I’ve added a new page that walks through the whole process—design tweaks, parts, assembly, and final testing—in clear, practical steps. If you’re interested in building or learning from the project, please read the full walkthrough.

I swapped my LM386 for an NXP TDA7052 to reduce distortion and gain more volume. The TDA7052 needs only power, an input and connects to an 8Ω speaker; I added a volume trimmer (I used 47k, 10k also works). Read the full post for the schematic and wiring details.
