We were working on the electrical wiring all day today. Headed home at sunset as the light was fading, and saw a nice sunset on the way out. Just thought I would share it:
A local tool shop
For those of you living in Thailand, this post might not be very interesting. But for those of you overseas, I thought this might give you a sense of the flavor of Bangkok. Praew and I discovered this small street side store front (‘tuktaew’) that has a remarkably good selection of tools and tool heads.The…
Some more progress on the sewage
The aerobic treatment system and the effluent cistern have been installed and hooked up. Here is a picture from today: You can see what is underneath in this post from a few days ago. Now we just need to build a cover for the cistern and a pump to pump the effluent to a secondary…
First results from low thermal mass construction experiment
When we had the first house designed, my primary design goal was simplicity. This is not just the simplicity of construction, but also the simplicity of maintenance as well as function. This includes things like no “hidden spaces” where rodents and insects can hide and make nests, or for hidden water leaks to make a…
Sewage system mostly completed
Sewage is rarely people’s favorite topic, but in a home, it is a very important one. Nothing exemplifies this more than working on the electrical wiring around the new house and realizing you really need to use the restroom. And then you remember that you can’t because the sewage system hasn’t finished installation. Well, the…
Power switching problem solved! It only took me about 5 years.
In order to solve the long time problems plaguing my attempts at creating fast switching high power electronics circuits, I’ve decided to take a crack at simulating it using ngspice. Here is a view of the kinds of ringing I am getting whenever the FET opens at load: The very large spike (too large to…
Utility trench finished and closed up
The past few days have been hectic. We added a second water main pipe just for redundancy. (It will remain unused until we detect a problem in the first pipe at some point in the future.) But that was the easy part. On the last day that we had the excavator rented, we needed to…
First attempts at modelling a FET in ngspice
In this post, I will show some simple experiments I ran to adjust the built in FET component of ngspice to model a particular FET. This follows up on this previous post where I showed how to install ngspice and run some preliminary experiments to model a zener diode’s behavior in a circuit. The FET…
The pond is done: time to party!
For the past 3 months, several of our workers have been helping to wash the gravel and sand to fill up the regeneration zones of the pond. This last week it is officially finished. At this point, we are now done with the pond digging, the sand retaining walls, the pipes to run the water…
Finished digging the trench for water and electrical supply
We’re now getting ready to run the final water and electrical mains to the first house. The trench has been dug the whole way about 1m (~40in) deep. The water main pipe has been laid down, but the HDPE pipe for the electrical won’t arrive for a couple more days. We are actually thinking to…
