I have earlier posted about Audio trends and snake oil. What annoyed then and still today in marketing and media that too often today then talking on hi-fi, science is replaced by bizarre belief structures and marketing fluff. It seems that there too many snake oil rubbish products marketed in the name of hifi. It →
I have made earlier a post on electrical car charging cables and charging stations technology. This s a continuation posting related to it. This posting links to DIY projects related to electrical vehicle charging cables. Those cables are quite expensive, so some DIY persons have tried to make their own versions. Some even claims have →
There is a growing interest and investment in electric vehicles infrastructure. To change those electric vehicles here are many different options how this can be done – with different benefits and disadvantages. The charging time depends on the battery capacity and the charging power. The charging power depends on the power available from the power →

Software-defined radio (SDR) technology can be used for many interesting technical experiments. With listening only SDR you can do many interesting things, but having a SDR that can also transmit opens many new doors. Here are some interesting videos related to SDR and cyber security: Universal Radio Hacker – Replay Attack With HackRF Download here: →
One of the key concepts in electronics is the printed circuit board (PCB). A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks. Simplest PCBs have only insulation board with copper traces on one side. More complicated PCB is sort of like a layer cake or lasagna- there →
