Of life and love

The meaning of life finally revealed (or not)

Preview

I've recently thought a lot about the concept of love and how it relates to life. This is partly because of my past, partly because of how the Finnish society is. A stream of consciousness awaits you in the Off-world colonies - just follow the hyperlink to go down the rabbit hole.

Metal strap rocks

I like to fix things using metal strap

Preview

I guess most people tend to resort to something specific when something needs fixing. The most common must be duct tape. I like metal strap, the perforated variety. In this short article I introduce some ways in which metal strap can be used for a lot of things.

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.

Widening narrow ice skates with a DIY tool

I guess I have weirdly shaped feet

Preview

As a kid, I never learned how to skate properly. Due to my wide feet it was super hard for me to find fitting skates. Eventually I just bought some decent ones and, since I don't have any contacts to boot punchers, decided to build a tool to make them more compatible with my feet. In this article I introduce the super simple tool that you can make too.

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.
