Building a Bamboo Planter (aka My Neighbours’ Cats’ Toilet)

Project Log

I live in a huge apartment block on the ground floor with a private garden facing a large communal garden. The view is nice, but the lack of privacy bothers me, so I have taken to growing bamboo to make a living privacy screen.

I don’t want to use commercial planters because most of the ones sold here use cheap pressure-treated softwood, and those don’t last very long. I want to use a naturally rot-resistant hardwood, and although they are also available commercially, they are extremely expensive for the sizes I need.

So of course I decided to make my own.

This is made out of Iroko, which is an African hardwood that is naturally resistant to rot (because of its oil), so it doesn’t need to be treated or coated in anything even for prolonged contact with soil (as is the case here). Apparently it’s also believed to have super-natural properties in Yoruba folklore. How cool is that? It’s a beautiful wood.

Building an ESP32 Light Controller

In this post I am going to do a deep dive into the electronics design for my simulated sunrise/sunset aquarium light project. If you have not read that post, I recommend starting with that. Disclosure: JLCPCB is sponsoring my projects, but I had already been a big fan of their …

Simulating Sunrise/Sunset For My Aquarium

Why? This is what I started with: It’s… fine, but the lighting left a lot to be desired. Lighting is not just aesthetic – those are real plants, and plants require light for photosynthesis. A lot more light than most people imagine! In a tank of this size, with plants …

Designing a 13A Arduino Motor Shield

I am currently working on a tensile strength testing rig that will be detailed in a future post, but as part of that project, I need an Arduino shield that can drive a 12V/13A linear actuator. Electrically speaking, linear actuators are just DC motors. However, because I need to be …
