After the “WiFi OLED Mini Weather Station with ESP8266“, here is another one: this time with Touch LCD :-):
LCD Weatherstation with ESP8266
I’m convinced that this ‘Internet of Things’ thing-thing is not real. Pure marketing and buz words without any added value, right? The IoT hype is so bizar: it must be originated by aliens which have taken over the brains of all the Pointy-haired Bosses of the world? There is no useful application or use case out there!
But wait! There *is* actually good use case, at least for the geeks of this world. We all love clocks as we want to know the time, and we all love the weather forecast so we can plan accordingly. At least I usually do :-).

I have been asked to share what I’m creating with the laser cutter. So here is one more design: a wooden chest box:

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.

We are creating a new course (PRG-G) at the Lucerne University. This course teaches C programming and is part of the new curriculum in EE (Electrical Engineering). Every student will receive a microcontroller board on an extension board as give-away, in a custom card box for the board and cable. To make things a bit more exciting, why not laser engrave that box? That gives me a perfect excuse to experiment with the laser cutter 🙂

There are people around me who think I’m crazy. And they are probably right. Who else would buy a machine from someone he does not know. I have to pay upfront. It is not clear how things will get delivered, what gets delivered, or if it gets delivered at all. Up to the point I can lose the money I have spent. Best of all: that machine is dangerous enough to potentially kill me. And it has the potential to put my home on fire too. Well, that sounds like an exciting weekend project, or not?
