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 :-).
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:
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.
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
It is never too early to start thinking about Halloween projects :-).
rendered Eyes with i.MX RT
When I ordered originally the MIMXRT1050-EVK from Mouser, it was without the LCD display (see “MCUXpresso IDE V10.1.0 with i.MX RT1052 Crossover Processor“. I ordered the LCD for the board soon after writing that article, but I was too busy with the university lectures and exams to get a hand on it. Finally I have spent a few hours at night and I proudly can say: the display is working 🙂
The question has been: If I buy such a 50 Watt cheap laser cutter from China, how many Watts does it really have? I have read all these stories that usually what is advertised is only the theoretical maximum I could get, and will not be realistic at all. This article is about how I tuned the machine and how much I got out of it.
