This time, I will repair my daughter’s Lego Duplo train engine. It is from a Train Deluxe LegoDuplo 10508 set, but I found two issues.
First of all, the locomotive has to make “Tchou Tchou” sounds, but it remains silent. It is an advantage for my dad’s ears, but I like to fix everything.
Secondly, the locomotive is slipping and cannot climb the bridge hill properly.
A fresh article with something new to troubleshoot. This time I will repair a tower rail that belongs to my father. It is an Airelec Indigo model, also sold under the Noirot brand.
This heater has two functions. A heating mode with a single heating element and a “forced operation” mode that allows you to quickly heat the bathroom before taking a shower. In the last mode, the heater enables a second heating element coupled with a fan.
This device works perfectly in simple heating mode, but when I enable the “forced operation” mode, the fan starts for a brief amount of time, then turns off, then turns on again for two seconds and so on. After several minutes of on-off cycles, the fan works continuously. At first glance, it looks like a power supply or a chip reset issue.
Today is a sad day, my coffee machine is broken ! No more engineer fuel 😢 After multiple tests, it looks like the coffee grinder is worn out. Coffee powder is accumulating and it blocks the grinder. My coffee machine is making a troubling noise but it does not make any more coffee.
First good news is that Krups brand is distributing spare parts. You can find them easily on the internet. I finally ordered a new coffee grinder on Midi Pièces Ménager website for 75€ including shipping costs. Cost is quite high but it is less than 10% of the cost of the machine.
Here I will detail how I teared down the coffee machine and how I fixed coffee grinder issues. It can be useful if you have the same type of machine.
Update from April 29th, 2021 : Added machine exploded view
Hi everyone,
I work to redesign my personal website, which was close to clinical death.
I will try to add more content by opening a blog section.
Docs section contains document I use for my daily electronics hardware engineer job.
It will be exclusively in english, because it is the hardware engineering language.
I use theses documents for my work to do computation or to share data with partners.
I will bring to life an old fashionned personnal blog.
My goal is to write articles about technical topics, like machine repairing or interresting stuff I find when I browse the web.
This part will be translated in french and in english, because there is few technical french content available on the Internet.
I wish you a nice tour on my website !
Nicolas
