Hi, I'm Jay 👋

Programs made for the fun of it

My name is Jürgen Laschak and in my spare time I write small programs that make everyday life a bit easier for me and my friends – from the smart home to pizza night. I present the results here and share the source code openly on GitHub.

A hobby, not a product

All programs on this site are made privately and free of charge. There is no support, no guaranteed features and no promise that everything works without errors. You use them at your own risk; to the extent permitted by law, I accept no liability. More under Liability and Licenses.

Projects

Home Control

Android TV app · Flutter & Kotlin

One press on the remote opens a panel with your Home Assistant devices – right on top of the movie you're watching. Plus a doorbell that rings on the TV without stopping the music.

Android TV app · Flutter, Kotlin & C++
