Build log day 1:
I'm hereby starting a new project. The aim is to build some kind of machine that is able to operate completely independently without any tether. This means an onboard power source as well as a fully embedded control system. The task for this machine is unimportant but for the sake of proof of concept, I have set the goal for the machine to "moving around without crashing into anything". If I can succeed in that, I plan to make it interact with the environment in some way but I leave the specifics of that to the future. I thought about calling the project Dog, as in my own name backwards, but after thinking about it for a while I settled on Man as short for Mechatronical Android... continue reading
When I was in Japan a a year or two back I bought a kit for making your own folding knife from the big DIY department store Tokyu Hands. Since then I’ve been too busy with other stuff but now I finally had time to assemble it and I thought it might be fun to show how I made it.
The kit consists of two handle parts, a blade, two sets of screws, four washers, a stop pin, two pieces of sand paper, a small tool and the instructions manual. They come in different versions but I got the one … Read the rest
A little over a year ago I was unemployed meaning I had a lot of free time. I wanted to do something more meaningful with my time than just watching YouTube so I found a couple of craft project that I could do. One that seemed interesting was making a little stove, or rather a kind of alcohol burner, out of soda cans. To make it a bit more interesting I set myself a challenge. I wanted to see if I could build one of these soda can stoves using nothing but materials from the corner 7-11 and a Swiss Army Knife...continue reading
Me and my wife recently bought a new apartment. To get the style we want rather than what a designer recommends, and also to save some money, we have been doing a lot of DIY for the interior decoration. I think it turned out really well, especially for two inexperienced people, and I just want to show off a bit.
Above is what the apartment looked like when we got the keys. The boxes are for the kitchen appliances that the construction company would install later. My brother inlaw was kind enough the install the floor tiles in the kitchen … Read the rest
Back in May I wrote this article about building a passive AC. That time I attached it to the front of our living room fan and I found that while the principle worked the air flow was too low to give effective cooling. I also mentioned that I would like to try to fit one in a window to cool down the incoming air. Now, I’ve finally had a chance to test this concept.
The working principle is the same, as the air passes through the funnel it gets compressed which lowers the temperature. Last time I used standard 500 … Read the rest
A while ago I stumbled upon a video showing some people in Bangladesh who had invented a kind of passive air cooler made from scrap bottles that could help poor people keep cool in the summer, you can read more about it here. I think it’s a neat idea so I figured I would try to build one of my own. The version shown in the video fits in a window but I figured i could fasten it on the front of a fan for increased effect. This post is a build log detailing the process.
As can be … Read the rest
