A while ago, I’ve bought the ISDT C4 EVO USB-C-powered battery charger to replace my MAHA C9000 (of which there seems to be a new “Pro” model available). The ISDT charger gets regular firmware updates which add new features and optimises the charging modes for different battery chemistries. Up until firmware 1.0.44, everything worked fine.… Read More: ISDT C4 EVO battery charger firmware downgrade »
I’ve recently acquired an old HP EliteBook Revolve 810 G3 and wanted to reset that to the factory state. Luckily, this already supports HP’s Cloud Recovery feature where you can download the recovery image from the Internet and write it to a USB drive. There’s even a choice between Windows 7 and Windows 10. However,… Read More: HP EliteBook 810 Cloud Recovery and GPT »
After adding a new penguin to my zoo and moving around a few services, I had the need to re-route HTTPS traffic to a different host for doing all the SSL handling (which would then send a request back – but via HTTP on a different port). The simplest way to do this is to… Read More: Simple port forwarding using nftables »

And as a former fan of Google Health, I liked the way… Read More: Syncing Garmin Pulse Ox data to Apple Health »
I’m a data hoarder. And as such I still have email conversations going back to 2003. To not clog up my provider’s disk space and, because I don’t want to donate all these old conversations to Google, I’ve setup my own email archive using dovecot. Early versions ran natively on one of my Raspberry Pis,… Read More: Traefik as a TLS proxy for IMAPS »
I usually have a few SMB shares from my NAS mounted on my Raspberry Pis. However, I rarely need to actually use them and scripts only need them once a day (backup). So I figured: Why let the OS bother with keeping those mounts active all day long when there’s a better way? Cue autofs.… Read More: autofs everything »
My private SSH key is ancient. And thus it still was in the “old” RSA format, recognisable by the header: This never was an issue. Everything works fine. Until now. While trying out GitFinder, it just didn’t want to accept my id_rsa file and always came back with “invalid format”. I’ve also made sure to… Read More: SSH key suddenly in “invalid format” »
After moving to a new place, I had to put my ADS-B handling Raspberry Pi 2B into a cupboard far from any network connection. So I’ve plugged in a cheap USB WiFi dongle and connected it to my WiFi. However, I don’t know whether it’s the dongle or something specific to the RasPi2’s USB implementation,… Read More: Flaky WiFi dongle toggle script »
I’m using a ConBee II Zigbee stick by Dresden Elektronik but switched from their own Phoscon/deCONZ software to the Home Assistant ZHA integration. While I didn’t have any issues with my few Zigbee devices, today, I’ve noticed that there’s a newer firmware available for my ConBee stick. Usually, the firmware update is handled by the… Read More: ConBee II firmware update via Home Assistant / ZHA »
