Before I got my first 3D printer I wondered why everyone printed this little cute looking boat called Benchy. And guess what I’ve printed first after I’ve assembled my Prusa i3 MK3S+ ? Of course, a Benchy 🙂 History of the Benchy The Benchy is around since 2015 and is a used as a benchmark…
Heute eine kleine Sammlung an Bewerbungstipps für technische Berufe, entstanden in Kooperation mit Tino Dietel, Engineering Lead bei TRADEBYTE. Ein paar Tugenden vorweg Rechtschreibung Nichts bringt uns mehr auf die Palme, als Rechtschreibfehler: Verben werden klein, Nomen werden groß geschrieben. Nutze bitte die Rechtschreibprüfung in deinem Schreibprogramm. Lass noch jemanden drüberschauen, wenn Du dir unsicher…

And yes that is possible and can come in quite handy. For a Flask project I wrote a decorator to manage authorization of endpoints. I wanted to grant access to…
Assembling the Y-Axis of the Prusa i3 made a lot of fun. So up to the next: X-Axis The assembly is pretty straight forward. The manual has enough imagery and the description is very detailed. One tip: instead of using the included allen keys consider using a little electric screwdriver like the Bosch IXO. It…

Time to improve these sites 🙂 Greasemonkey overview Greasemonkey is a browser plugin which lets you inject client-side JavaScript into the webpage just as the developer could have intended to…
Motivation Sometimes you need to find files across multiple directories and / or directory hierarchies according to certain pattern. E.g. find all image files with the jpg extension You can use it to find files in a directory by using wildcard semantics. Let’s say we have a directory structure like this: glob_test/ |– dir_a/ |–…
The Tools Prusa included some tools. Pliers, a screwdriver and some hex wrenches. Their claim is that this is all you need to assemble the printer. While that might be true you should consider some additional tools. An electric screwdriver with the correct bits speeds up the process. And a hex socket should be used…
As mentioned in my New Year’s Resolutions and Technology Learning Roadmap 2022 I wanted to learn about 3D printing. After a serval hours of contemplating and researching I finally bought a Prusa i3 MK3S+ 3D Printer. I’ve decided to buy a kit instead of a fully assembled version to save a few bucks and to…
Motivation Understanding Gradle is mandatory if you want to build good Android apps Bare Minimum This is the bare minimum you need to be able to compile and run an Android application: plugins { id ‘com.android.application’ id ‘kotlin-android’ } android { compileSdk 30 defaultConfig { applicationId “de.creatronix.myapplication” minSdk 21 } } dependencies { implementation ‘androidx.core:core-ktx:1.6.0’…
