I just updated the flat boxes set. All existing boxes got a new revision, with an even better wall profile and there are five additional boxes in this set. Improved Wall Profile If you compare the corner for revision A and revision B, you see the difference easily. The corner in revision A has an…

Flat Storage Boxes Set for 3D-Print
Finally, my tests of the flat storage box are finished. 🎉 The main issue I had, was the spot for the labels. With the geometry I used in the regular and tall boxes, it took too much space from the flat ones. I solved this using a special profile for this set. I personally designed…
Organizer Boxes Optimised for 3D-Print
One of the reasons I didn’t publish as many articles are before, is I am still organising my new lab. Because of the current pandemic, everything got delayed and there is still a lot of material which needs to be organised. After reviewing many existing designs and didn’t found one which matched my needs, I…
Always-On Firmware Example
Recently I published a simplified version of the Always-On project hardware. Read this post for details. Today I publish a firmware example for the Always-On project. This firmware is written for the PlatformIO environment using Visual Studio Code. It is using a special adaption of my HAL layer for PlatformIO using the Arduino layer for…
Stencils from OSH Stencils Arrived
Today the stencils from OSH Stencils arrived for the Swiss precision timer project. I used to work with steel stencils for all my previous projects, therefore the polyimide film (3mil) ones feel very flimsy to me. I will see how they will perform adding the solder paste. Pricing The cost of the two stencils, without…
Small Boards for the Swiss-Precision Timer
I am working on several projects and one of them is called “Swiss-Precision Timer”. It is no art-related project, but like like a small utility. The prototype boards were produced by PCBWay in very good quality. It is a two-layer board, just 37x18mm (1.46″x0.71″) in size. There are a number of really small SMD parts…
How to Write Custom Snowflake Patterns
In this article, I will discuss how to write custom patterns for your snowflake decoration. This is a rather advanced topic, and there are a number of prerequisites that are required and listed below. Nevertheless, it is rewarding to you see your very own pattern displayed on the decoration. You must solder a 5-pin programming…
Programming the Snowflake Decoration
In this brief article, I will discuss the requirements to flash a custom firmware to your Pimoroni snowflake decoration. I assume you have some programming knowledge and have previously worked with an Arduino Uno or Adafruit Feather. Required Hardware For the Pimoroni version:5 pin programming header. One for each snowflake. SWD programmer. Jumper cables or adapter…
Candlelight Effect
Here I briefly document a very realistic candlelight effect you can build with very few components. It works best if the device is placed in a jar or behind a screen, where the Neopixel ring is not in direct sight. You will find all the required information, schema and the firmware to build the device….
How to Wire the Snowflake Decoration
If you own an original snowflake kit or produced boards from the sources, you have to wire them by yourself. The pre-assembled kit from Pimoroni comes with some nice flex-cables, but you may want to replace them with more decorative ones. Here I explain how to create a custom wiring for your snowflake decoration. Layout…
