There are many questions on using a Chromecast or AirPlay devices (like the new Sonos devices with Airplay2) on a different VLAN. First of all, I think it is a good habbit to put all your IoT devices in a separate VLAN since it's easier to manage, protect/secure and isolate.; IoT devices often use [...]
When I touch my Tastsensor near my bed with the “Wake up” scene, the light swiches on, the bathroom lights switches on and in the Kitchen the Light and the TV should switch on. Problem with Samsung TVs (and a lot of other brands) is that they don’t do Wake-on-Lan [...]
The first Gira Tastsensor I bought was a tastsensor 2. Then Gira came with a new model: Tastsensor 3. Unfortunatelly this new model had a different background-light color (blue) while the Tastsensor 2 was having a green background light. So I couldn’t use them next to each other and actually using them in the same [...]

The screen stayed black. My first thought was the Power board, a dried capacitor, a (physical) broken part on it or [...]
I needed a proper roof ventilation to cool my server room. Noice (dB) and power usage are the most important factors for me. I tested many options and finally bought a Zehnder/StorkAir MX110 Fan. This fan is really quiet, has low power usage and you can buy these quite cheap [...]
I recently build an Out-of-Band (OOB) management network for Utrecht University with Moxa Terminal servers (CN2610-16-2AC). The Moxa Terminal servers had all RJ45 (serial) ports. However, connecting it with a normal network cable, a cross-cable cable or a Rollover cable didn’t work. I found the pinout and made a drawing of it in case you [...]
I’ve scanned all my documents (incomming invoices) in TIFF but also have a lot of documents in PDF and DOC(X) format. Now when something gets broke and I need to return it to the shop I’m often looking for that invoice, sometimes I don’t even know at which shop I bought it. Imagine I could [...]
