A fully automated, ML-curated news aggregator. It crawls tech sources, scores relevance, and generates summaries with a local LLM before deploying to its own subdomain.

20h of integration time reveals the fine interstellar dust in our galaxy and also the bipolar outflow of ionized gas from M82.

Stand designed in FreeCAD charges an Apple Watch and iPhone at the same time, while the phone starts Standby mode automatically.

To have a completely local, private and secure vacuum robot, I hacked it to install Valetudo. This allows the robot to run its own webserver, so it is no longer depenend on external servers. Also it can be controlled via MQTT.

A Hall effect sensor measures the position of the floating magnet and keeps it centred using an electromagnet controlled by a PID controller. All the electronics are housed in the hand-made base.

Collecting lights over several nights resulted in this beautiful image. A narrowband filter for Ha and OIII was used to improve contrast on these faint nebulae.

Thanks to the successful petition on ‘balcony power stations’ and committed individuals such as Andreas Schmitz, we are now able to meet a large proportion of our electricity needs ourselves. Some of the electricity we don’t use ourselves is used for citizen science projects, such as Folding@Home.

A DIY etched circuit board designed to control LEDs in sync with the music being played. An Arduino measures the signal voltage after low-frequency sounds have been filtered through a low-pass filter.

A 3D animation of our astrophotography setup, created using Gaussian splatting. The setup currently consists of a Fuji X-T5, a Samyang 135mm lens and a parallactic tracking mount. The lens mount was 3D-printed, which also allows for very precise focusing.

First try on painting with Procreate on iPad. With techniques from Bob Ross even a laymen like me can create decent images.

This picture of M31 shows three layers: a solar flare from earths orbit, stars from our own galaxy and with Andromeda a whole other galaxy with a distance of 2.5 million light-years.

I designed this grow box so that I always have a fresh supply of herbs. It features ventilation and lighting, the spectrum of which can be adjusted as required (blue light for compact plants and red light for taller ones).

Photographing C/2023 A3 proved to be quite difficult due to thick cloud cover. However, a brief spell of clear skies made this image possible.

To create lovely lighting over the dining table, I designed this lamp, which not only provides high-quality light (CRI >95) but is also integrated into my smart home via MQTT.
