Ever since stumbling over Cyrill Künzi’s article about the Sonicare brush head timer reset (which I’ve written about here), I’ve wondered what else is stored in the data. This is what a dump of the Mifare Ultralight NTAG213‘s memory from a white Sonicare A3 Premium All-in-One head looks like: The memory is organised into “pages”… Read More »
I’ve barely touched my Switch and was running some old Atmosphère version and Firmware 19-something. As someone not that deep in that topic anymore, here are the steps I’ve needed to get it updated to FW 21 – ready for the latest and greatest games. (Mostly for my own reference in the future.)

Synology DS415+ and the Intel Atom C2000 clock signal issue Back in January 2015, I’ve bought a Synology DiskStation DS415+. It came with 2 years… Read More »
By now I have 2 of those Ugreen M.2 NVMe USB 3.2 SSD enclosures. One of them is attached to my DELL monitor which is attached to my MacBook Pro M1 for TimeMachine backups and just works™ for almost 4 months now. I’ve recently bought a second one (and also the same SSD as in… Read More »

They have a Realtek RTL9210 chip which does support the “discard” or TRIM operation to mark unused space on the SSD. However, some… Read More »
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 »

However, I don’t know whether it’s the dongle or something specific to the RasPi2’s USB implementation,… Read More »
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 »
Back when I bought my Nintendo Switch, I made sure to buy an unpatched one – turning all the different boxes in the store upside down to read the serial number on the bottom and compare it with the list I had on my phone. However, apart from some experiments with SX OS and later… Read More »
Modern heads for Sonicare toothbrushes come with a small chip that records not only the type of head, but also how many seconds you’ve used it – so the head unit can remind you that it’s time to swap the head for a new one. This isn’t purely for monetary reasons, especially as the unit… Read More »
