I always have been fascinated by electromechanical stuff like these Flip-Dot Displays.

“java.net.SocketException: Connection reset”: Check your Windows Updates!
One of the most frustrating part developing embedded applications is if the debug connection fails somehow: with all the different factors like operating system, virtual machines, USB ports and hubs, debug probe and firmware a ‘connection failed’ is my nightmare. And this is probably the most frustrating parts for my students (and myself!)
I do have a growing list of tips & tricks in “Debugging Failure: Check List and Hints“, so check this list. What I just have added is an entry for
java.net.SocketException: Connection reset
It occurred for a few students when they wanted to use the on-board CMSIS-DAP LinkServer debug connection on the NXP LPC845-BRK.

Hey Google: Find ‘Error from StubMonSemihost: “monitor” command not supported by this target.’
Something what I say quite often is: “Google is your friend”. It means that the answer to many questions can be found with an internet search engine. And I have to admit that I have to ‘google’ my own articles to find solutions for problems I feel I have seen in the past too :-).
But for the one problem below I did not find anything: not on my own blog, and not anywhere else in the internet:

New MCU-Link Debug Probe from NXP
The NXP MCUXpressso IDE Release V11.2.1 gave a hint about a coming new debug probe, the MCU-Link which is available now:

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.

Tutorial: Adding FreeRTOS to where there is no FreeRTOS
FreeRTOS is pretty much everywhere because it is so simple and universal, and it runs from the smallest to the biggest systems. But it still might be that for the microcontroller device you have selected there is no example or SDK support for it from your vendor of choice. In that case: no problem: I show how you could easily add FreeRTOS plus many more goodies to it.

“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
DIY ‘Meta Clock’ with 24 Analog Clocks
Human since 1982 claims
“Human since 1982 have the copyright to works displaying digital time using a grid arrangement of analog clocks…”
I’m not a lawyer, but without obligations (imho) I have removed the content.

World Stepper Clock with NXP LPC845
I really love clocks. I think this is I am living here in Switzerland. Beside of that: clock projects are just fun :-). After I have completed a single clock using stepper motors (see “DIY Stepper Motor Clock with NXP LPC845-BRK“), I wanted to build a special one which is able to show up to four different time zones: Below an example with London (UK), New York (USA), Beijing (China) and Lucerne (Switzerland):
