I was about to polish some SDR knowledge and try to capture a - for me unknown - device emissions and see if I could convert that to 'real' data. The one thing on my desk was a BMW display key fob so let's go for it! 🏃♂️➡️...
Finally, after so many weeks, the hobbyist CNC from Makera ( www.makera.com ) did arrive. WHAT A JOY! 🎉🤪 Having a bazillion of projects in mind, we need to get it started properly right away. But first of all an ode to the Carvera: It is a...

I've always been looking for a nice logic simulator and found - by accident - Logisim Evolution a nice utility to work with logic schematics and logic simulation. Useful Links https://www.youtube.com/watch?v=gYmDpcV0X7k...
It turns out LEGO® Boost is quite a cool low-fi robotics thingy to play around with. Kids off the age of 7 could easily gain first experiences. Even for young grown ups there are quite some nice things to build and discover (admittedly those...
For everyone in IT there is this one single bike one learned riding on. Albeit my first experiences with computers reach back to a Sinclair ZX81 and its Sinclair BASIC at the age of six, it took another three years to get a proper home computer....
I've always been sort of reluctant of installing or using auxiliary apps in order to apply to this one special use case. Wouldn't it be better to use the stuff already there and giving far more 'ins' and 'outs' from a process perspective? This is...
