It was one of those summer mornings when time seems almost suspended: a tranquil pocket of stillness tucked inside the city’s otherwise relentless pulse. The grass was already warm with sunlight, and the air carried the scent of cut leaves and waking soil. Beneath the shade of a tall plane tree, a small group had gathered on yoga mats in quiet attention to breath and body. At the centre stood the teacher, fluid and unhurried, her posture calm enough to make the whole park feel as if it had lowered its voice.

Measuring electrical power over long periods is often more useful than taking a single snapshot. A device may behave perfectly during a quick bench test and still reveal unexpected current peaks, warm-up drift, sleep-state anomalies, poor power factor, or efficiency losses only after minutes, hours, or even days of observation.

That is the reason I wrote GPMLink, a small logging utility for the GW Instek GPM-8310 AC/DC power meter. The goal was simple: connect the instrument to a computer over Ethernet, query its measurements at regular intervals, display the data, and save a continuous CSV log that could later be inspected, plotted, or imported into other analysis tools.

PiKrellCam Reborn was my attempt to extend one of the most useful motion-detection and surveillance applications ever written for the Raspberry Pi. The original PiKrellCam already provided a remarkably complete camera interface: live preview, on-screen display, motion-triggered video recording, media browsing, scheduled commands, and a highly configurable web UI. My fork added a second layer to that idea: an environmental logger for temperature and humidity, integrated directly into the same camera dashboard.

In the very last stretch before the pandemic, I began playing organ with SAKILI, a Berlin-based roots-reggae and chanson project led by Antoine Villoutreix. We rehearsed in Pepe Rasmus Weissgerber’s practice room around Ostkreuz: a warm, lived-in Proberaum with that very particular Berlin mixture of music, craft, odd equipment, wood dust, friendship, and unfinished plans.

I never played a gig with SAKILI. My whole chapter with the band happened in that rehearsal room, where I tried to learn and play their complete setlist on organ. It was beautiful, but it was also daunting. Reggae is not as simple as it may sound from the outside, and at that time I was going through a very stressful period in Berlin. Eventually I left the band, and not long after that I left Berlin for good.
