From the last plastic shredder machine post, we cast the walking stone (30 x 30 x 5 cm) by mixing concrete ready-mixed mortar and plastic.We experimented with 2.5%, 5%, 10% plastic by weight. We cast it all by put the pure ready-mixed mortar (about 1 cm height) and then put plastics-mixed mortar until the mold…
Plastic Shredder Machine: heading towards zero waste
What can be done with all of the waste plastic around the land? There are places that recycle plastic, but not all plastic gets recycled. Bottles and cups do. But what about the foil/plastic wrappers, etc? There doesn’t appear to be any recycling places around Bangkok that recycle these. When they do accept it, it…
Cistern water level monitor
The cistern in front of Ban Mae has a steel lid 1.2 x 1.2 m approx. weight is about 10 kg. If we want to know water level in the cistern, we need to lift it every time. It would be better to have a water level monitor we could easily see every time we…
Ban Rim Nam Cooling experiment
Since the weather in Thailand is very hot, the roof temperature of Ban Rim Nam can get up to about 50C (inside!). (This is inside of the 1 cm insulation.) At the same time, under the house is about 29C. So we thoughht about cooling the roof to decrease the temperature inside. In this experiment…
Pink water lilies
My coworker gave us these water lilies from her home town a few months ago. We didn’t think it would survive, but it thrived. This week it finally flowered.
Building a slow sand filter to process greywater in floating house
The usual disclaimer: processing of greywater or any other part of a water system in your house is critical and can lead to severe problems if done wrong. Even greywater can contain significant amounts of E. coli and other pathogens. Please do not try this at home. As always, I describe my experiments below for…
A Kingfisher on the balcony
This picture was taken by Than when he was talking with the workmen at BaanLoiNaam. It appears to be a kingfisher sitting on our balcony. It is a rather cute looking bird, so I thought I would share.
Storing the pond ladder when not in use
Most of the time, I won’t be using the ladder to climb down from the balcony of BaanLoiNaam (the floating house) into the pond. And when it is just sitting in the water, over time it seems to get pretty dirty. So my intention from the beginning was to be able to remove it from…
Driving an electric ferry boat around the pond
A few weeks ago, I finally got around to testing the thrusters on the ferry boat. These are very small thrusters meant for a small ROV (remote operated vehicle), but I don’t intend the ferry boat to go very fast. First we mounted a simple arcade joystick into a box with a microcontroller and connected…
Protecting a mobile floating house from lightning strikes
Having added lightning rods to both of our non-floating houses on our land along with the appropriate binding and grounding, I have struggled to figure out how to similarly protect BaanLoiNaam, our floating house. This isn’t just an academic issue. One of our neighbors had their house burn down this year due to a lightning…
