We are getting very close to the point on BaanLoiNaam that we will be adding the propulsion systems. To review, the house is designed to be able to operate completely independently from land and to move around the pond under it’s own power and rotate to track the sun, etc. So before I can spec…
ROV Thrusters
We’ve stalled a bit on the ferry boat due to the electronics. The BLDC controllers we’ve been tinkering with seem to work, but still have some kinks to work out. And on the list of all the projects I’ve been working on, this has been down quite a ways and isn’t getting as much attention…
New project: Building a houseboat!
I have an idea for a new project… Praew and I have been very interested in Tiny houses, as the houses we have built have gotten smaller and smaller with each iteration. First BaanMae (my mother-in-law’s house), then BaanRimNaam (the one we are living in now), then BaanLoiNaam (the floating house). BaanLoiNaam is a remarkable…
Slow but steady progress on the BLDC motor drive circuit [technical]
Things have been going a bit slowly on building the BLDC drive circuit for the ferry boat propeller motors. Mostly this has been due to being busy with other things. But nonetheless we’ve been making slow but steady progress over the past few weeks. One recent big help was the purchase of a new oscilloscope….
Keeping the pontoon jig in good order
When we made the pontoons for BaanLoiNaam, I made sure that all of the pontoons were built (and mounting holes drilled) using the same jig so that they would be interchangeable. I noticed the jig rusting on the ground the other days and asked the workers to clean it up and add another coat of…
Crazy modular sliding bed design in BaanLoiNaam
The interior of BaanLoiNaam is only about 3m x 4m, which doesn’t leave much space to squander. Sure, we have an outdoor bathroom and kitchen area (washing dishes, cutting vegetables, and gas cooking range) to try to leverage the balcony space as much as possible to complement the limited interior. And when the weather is…
BaanLoiNaam: More progress on walls, doors, and windows
The second of four walls is now completed on BaanLoiNaam. It is now really starting to look like a house: The nearer wall with the door in the middle is the way out of the house to the outdoor bathroom area. The roof overhangs this so it should be mostly sheltered. The dream idea is…
BaanLoiNaam: Turning the house 90 degrees
Last week, I noticed that the orientation of BaanLoiNaam when the workers were building it had the longer roof facing west. Since BaanLoiNaam is designed for a completely disconnected operation, it will be getting all of the house electricity from solar panels on this roof. And being in the norther hemisphere, the sun is generally…
BaanLoiNaam: one wall completed
We have now finished one of four walls! Just three more to go. 🙂
Back to the BLDC motor drive circuit
The motors we mounted onto the ferry boat are brushless DC (BLDC) motors. Until now, I haven’t actually successfully built a BLDC motor drive circuit. Mostly it is because we’ve been busy with a hundred other things. But now that the motors are mounted on the ferry boat, and we have to start thinking about…
