Advent Calendar 2022

It is already December 1st, and time for a new Advent Calendar. This year the design includes birch plywood with PMMA, SK6812 RGBW LEDs running with a Raspberry Pi Pico board, building a small village.

Eyeglasses Case created with CNC and Laser Cutter

In many cases I prefer wood as material: it has a warm feeling and with its texture it makes things unique and special. For some time I was thinking about creating a wooden case for eyeglasses as a gift. And here is a first version of it:

DIY Split-Flap Display

Split-flap displays are electromechanical display devices, which were common in airports or railway stations a few years ago.Unfortunately, most of them are gone and replaced by LED displays. Why not create a DIY version of it?

Advent Calendar for 2021

Switzerland got a snow cover, with more snow coming the next days. December started, and so did the Advent season. Similar to last year, we wanted to create a special advent calendar, which is then is given to families in the neighborhood who deserve it, because they did so much for our community this year.

Last year it was a special house created mostly with a laser cutter. This year I took advantage of having a desktop CNC down in the basement. The result is a ‘tree’ filled with small boxes made of oak wood:

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 :-).

Round MetaClockClock

It has been a while since my last MetaClockClock, and with the continued shortage of electronics on the market I had no chance to order new parts. But I still had some remaining parts, and with the modular design of the ’round’ clocks I was able to build up another one, but this time with even less than the usual minimum of 24 clocks:

So if you are up to build a MetaClockClock with less clocks, this might be the way for you.

Full Bathroom Remodeling (with the Help of a 3D Printer)

This is about one of my ‘long running projects’: I happily can report that the missing last piece has been installed after 16 months from the start of the project: the ‘3D-Printed-Supported-Driftwood-Bath-Tub-Shower-Gel-Holder’ 🙂 :

This is the ‘official finish’ of a complete bathroom renovation and remodeling. It has been a joint project with the help of friends, contractors, my family and my brother in law (who is an outstanding carpenter and cabinetmaker), plus the Ultimaker2 3D printer which contributed many ‘background and hidden’ features.

I invite you to a virtual time travel. I hope you enjoy it and get inspired….

MetaClockClock V4 for the Year 2021

I had a few of PCBs left over from the V3 MetaClockClock, and originally I planned to finish a build with them by the end of 2020. But as always: things took a bit longer than expected, so I finally finished it today on the first day of the year 2021.

The build uses the same hardware as in the previous V3, but instead of an ‘artistic’ canvas background I decided for a more natural and wood design:

Mobile Teacher Tool, Rev 2 by Gerhard

It is always great to see if someone is picking up my work and produces something even better :-). In this case, Gerhard Székely took my DIY Portable Video Conference, Sharing and Teaching Device and created an awesome version of it:
