Preview

For the longest time I was considering to start playing the drums. A few years ago I finally did buy a cheap electronic drum set. This review I was supposed to write already two years ago, but better late then never I guess. Check it out to learn how a cheap drum set works for a beginner!

Updating PC hardware in the 2020s

Optimization still requires knowledge

Preview

In December 2019 I updated my PC to cutting edge technology. Unlike in my older PC article, things aren't yet obsolete, so I figured I'll write what one needs to bear in mind if they want to optimize a new PC build. I'll also discuss some hardware/firmware bugs that still bother modern components.

Preview

If some of your favourite songs happen to be originally tracker music, you must have wondered what would be the best way to convert them into bitstream format. I did an empirical study about it. Read on if you, too, sometimes bang your head to a power plant techno.

ESP8266 deep-sleep repeatedly

How to deep-sleep for a long time and save power

Preview

I made my indoor plant a soil moisture meter which reports the values to Azure cloud. However, I had some trouble making my D1 mini board to sleep and wake up reliably. Turns out, just calling the deep-sleep function once doesn't do the trick. I had to deep-sleep for several shorter cycles before reporting the measurement. Check out the article for a brief how-to.

Ever since Bluez dropped support for Bluetooth audio using ALSA, people have been using PulseAudio to connect audio devices in Linux. However, there's a project called BlueALSA which supports high-quality cutting-edge codecs such as LDAC, and it works with pure ALSA. Read the article to see how to use it.
