This article is a new iteration on the wall clock I made a while back. (What can I say? I like LEDs, clocks and clock made up of LEDs…) This time I used a new PCB for driving the circuit and I designed a fully 3D printable enclosure for it …
Introduction With the recent launch of Windows 11 Microsoft also made having a hardware TPM module mandatory. Although this technology is not new (it was introduced in Windows 10 and Windows Server 2016), now, that most people can’t upgrade to Windows 11, it will (slowly) become mainstream.

Introduction I have seen many interesting modifications of (mostly) game controllers on the internet. They all have one thing common: they were specific to the controller in question. I wanted to design something that could be attached to any controller, regardless if it uses positive logic (button pressed = logic …
Introduction Although my “original” Spindicator itself was just a clone of this one, mine was well received by the geeks around the world! 🙂 A fellow diy tinkerer made an even better one with PWM control (very cool, indeed!). Recently, I was asked to do something similar for a custom XBOX 360 …
