For a long time I've wanted to get more into embedded stuff and closer to the physical world when it comes to computers. As a kid I was quite interested in electronics and tweaked some small stuff, but I never really got into programming anything. Now with the market full of cheap Arduino-compatible chips, I decided to hook myself up into the Internet of Things and make a WiFi-operated garage door opener. Check out the article for an overview of the project.
I wanted to have new earphones I could use when walking or doing sports. One of the requirements was they should be open design. I ended up buying the Sony SBH70 bluetooth earphones, found some shortcomings and tried to fix them with a little bit of modding. Read the full article to see some custom wingtips.
Most mortals have to listen to music in a somewhat small room - a closed space, which will usually result in boomy bass at some frequencies, and terrible flutter echo in the upper end of the audible spectrum.
Read this article to find out quick and cheap tricks to remedy the problems.
If one wants a silent gaming rig, nowadays they may just pretty much put a few extra drachmas in it and achieve the wanted results with little to no effort. But it hasn't always been like that. In this article I tell about my four-year-old computer and what I did to keep it silent. Some points might be of interest even nowadays.
Especially since getting an easily recurring tinnitus a few years ago I've been super careful not to play my trumpet without adequate damping. Wearing earplugs works, but doesn't feel or sound good, and it doesn't help the neighbours one bit. I decided to build myself an acoustic absorber tub. Read the article to see how it fares even in hard-surfaced rooms.
Acoustic panels can be quite expensive. If you are on a low budget or need not only to just dampen your small room's reverb but also attenuate some noise, building heavy acoustic panels might do the trick. In this article I'll show what I built a couple of years ago.
