So this started, as most things do, with a completely reasonable question: what's floating around in the radio spectrum above 1.6 GHz? Turns out quite a lot, and some of it is surprisingly readable with hardware that costs less than a decent...
The RESET Circuit A 555 timer is great! There are many applications and the book 'Much ado about nothing' is a great read if you want to know how this IC came to life. The easy way Per the documentation, reset should be pulled low at least...
Understanding the sheer size of a contemporary neural network and catching its intricacies is very hard at times. However there are a lot of people trying to visualise how those networks work. Here's a curated list of visualisations I found useful:...

A friend recently dropped a Denon DHT-S514 soundbar as it produced loud plopping sounds (the one we all know from our childhoods when DC voltage made its way to the speakers). 🔉 I did not expect an easy fix and it took me a couple of...
"Just remember that a CPU is literally a rock that we tricked into thinking. Not to oversimplify: first you have to flatten the rock and put lightning inside it." - @daisyowl, 14.03.2017 Sooo... This has been on my list for so many years now:...
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...
Trying to consolidate a bunch of interests is difficult at times! However bringing RF technology, photography and mechanical engineering together seemed to be a good idea. So this is the journey to develop a multi purpose tracking platform.......
Every wanted to drive a more demanding load with a Teensy? Search no more. A lot of motors you could use for various applications can be controlled using pulse width modulation (PWM). Let's take this DC motor. It comes with some decent torque...
📡 GNURadio is an excellent fit for all hacks around signal processing. Since setting it up on several OS X environments always created one pitfall or another I decided to write down the happy path most likely being successful 🤡 If not...
So, we all knew this would happen... I finally bought a Vector Spectrum Analyzer for a reasonable price. It came from University stock and seems to be in good conditions (besides scratches from rack mounting). There is some cleanup to do,...
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...
