From my previous MetaClockClock project, I still had some hardware available. So I decided to build my largest build so far: to clocks with 78 clocks each.

Customizable DIY RFID Business Card and Badge Holder with Victorinox Swiss Army Knife Tools
In case you are looking for an unusual business card, company badge or event badge holder, then this article is for you: A DIY RFID badge and business card with bling-bling addressable RGB LEDs to impress your customer, clients, friends at work or at a conference, packed with electronics. Plus it includes 10 original tools from Victorinox, the manufacturer of the Swiss Army Knife.
RP2040 with PIO and DMA to address WS2812B LEDs
I love the WS2812B (aka SK6812) addressable LEDs: they are inexpensive and available in different packages. I have used them in different projects, including the MetaClockClock one. I used the NXP Kinetis for these projects, but because they are not available any more, for a new project we had to choose a new microcontroller, with the Raspberry Pi Pico RP2040 as the winner.
Adding RGBW Wings and Enclosure to a Debug Probe
I’m using debug probes on a daily base. They have to be functional, and I value functionality over aesthetics. For cost reasons many debug probe vendors either only provide a bare PCB without enclosure, or the enclosure is made of simple plastic enclosure.
That’s OK. But when I received my NXP MCU-Link Pro debug probe, I wanted to add an enclosure for it: Not only to add protection,but to have it look cool too :-).
New MetaClockClock V3 finished with 60 Clocks
The holiday break at the end of the year is always a good time to finish projects started during the year. This one is about my ‘MetaClockClock’ Version 3.
2020 with Red Hands on Blue
New Version
I’m making progress with the new ‘Billion Light‘ modules (aka V2): the new design is more modular and easier to build and assemble and still looks awesome with the moving lights and clock hands:

Behind the Canvas: Making of “60 Billion Lights”
As promised I’m going to share more details about the “60 Billion Lights” project. It is about a project to build a piece of electronics behind a 100×50 cm canvas to show animations or to display information like temperature, humidity, weather, time or just any arbitrary text.

“60 Billion Lights”: 2400 RGB LEDs and 120 Stepper Motors hiding behind Canvas Art
It is one thing to create something ‘cool’ or technically interesting. But it is a completely different story to convince your girlfriend, partner, wife, family (or whatever you can name it) to hang something on a wall in our house or office. Then it is not about technology: it is more about design and art. So here is my attempt to solve that challenge:
Displaying temperature with a painted canvas, stepper motors and 2400 RGB LEDs
