Back in May, I posted about ordering an Angel Sensor M1. I did have some success tinkering with it, but I never got around to posting my results. After being asked about it a few times, I figured I should get it up on the blog. The device manufacturer supplies some experimental Python code on…
Pontoon update: attaching the skin
Here are a few photos of the pontoon welding in progress. Since we finished the frame in the last update, the welder is moving on to weld on the plate steel that I usually just refer to as “the skin”. We’ve finished the sides, front and back, and in these pictures they are welding the bottom. (The pontoon…
A rat chewed through my 3D printed overflow pipe mesh
If you recall back in March, I finished the overflow pipe and even 3D printed a plastic cover to keep the mosquitoes and snakes and other critters out. Well, that didn’t work so well. Sometime in the past week or two, a rat chewed through my beautiful cover. You can tell it was a rat…
Pontoon update: frame done
I swung by and took a look at the progress on the pontoon yesterday. The metal frame of the first prototype pontoon is done. The next step will be to weld on the outer plating. I’m excited to see if we can pressure test the plating successfully or not. After that we will begin the…
Successful first test of “smart lights”
Having built up and tested the peer-to-peer RS485 network protocol, it was only a matter of coding for a few days to write up the firmware for these “smart lights”. Here is a quick video capture of an early test: The 3 lights on the desk are the top part of the lamp posts. They…
New project: Building custom steel pontoons
We have begun building a prototype of our custom steel pontoons that Kong helped us work out a simple engineering design for. Here are the steel plates that we will use for the “skin” of the pontoon: In this picture, the workers are carefully covering the steel in high quality anti-rust coating. After the pontoons…
Rains of biblical proportions
After a record drought, we seem to have moved on to record rainfall this week. Just a week ago, Praew and I were walking around the pond and wondering why, despite occasional rains, the water level seemed to be stuck at a point that put the whole “floating house” idea in doubt if that was…
Restaurant: Anya’s Place
Today we went out tree shopping for the landscaping and stopped off for lunch at Anya’s Place, a restaurant located in Salaya. They have a very large selection on their menu (ridiculously so in my opinion), but the good part about that is it is pretty easy to find something to eat. Thai food, Chinese…
How fast is an AVR GPIO pin change?
A few months back, I saw this post from my friend Professor Montri Karnjanadecha regarding timing of an Arduino Nano pin. In it, he uses an oscilloscope to test what kind of speeds you can get from alternately pulling high/low a pin. But as he points out, he doesn’t get as much speed as he…
Very successful first peer-to-peer protocol test
I’ve coded up a simple test of the peer-to-peer protocol I’ve been discussing recently. Here is a picture of the set-up: For this test, I have 3 light posts transmitting short 10byte packets as fast as they possibly can given the constraints of the protocol. These constraints basically reduce to: You can’t send a packet…
