Google Pixelbook ‘Eve’ – Plain Linux

      Keine Kommentare zu Google Pixelbook ‘Eve’ – Plain Linux

For many years now I am on a quest to find my ideal mobile computing device, aka laptop. It should be small and lightweight so that it is easy to carry, but not too small so that I can still work on it. It should have decent battery life so that I can get through a day with light use… Read more »

ESP32 LyraT Audio Player / Internet Radio

Some time ago, actually by now already some years ago, I got myself an ESP32 LyraT audio development board. This is basically a pretty simple board demonstrating a bunch of interesting features of the ESP32 SOC, here embedded in the ESP32 WROVER module accompanied by an ES8388 audio codec connected via I2S to the ESP32, two NS4150 amplifiers to drive… Read more »

Cheap Surveillance Cameras & NVR – Hacking to work

Recently I needed some video surveillance camera setup for our small office. There will be some de-and then construction work in our area and I just want to make sure that this does not attract some morons… anyway. So I looked around and since this will definitely not be a permanent thing (I despise video surveillance!) I did not want… Read more »

JBL Live Pro+ TWS

Recently I purchased a pair of JBL’s Live Pro+ TWS wireless headsets. To be honest, I did not really need it but I needed to get rid of some flying miles at Lufthansa’s Miles&More shop before these expire. Since everything else in their shop was not really appealing to me I finally settled on this pair. I do not want… Read more »

Chuwi Minibook 8

By some lucky circumstances I received a Chuwi Minibook 8 from Chuwi’s mothership company Zwide. Wondering what this is? Well, it looks like this: Which one? Well, kind of all four because it has this “yoga” hinge so that you can bend the display over by 360 degrees. But the most striking thing about the Minibook 8 is its size… Read more »

Linux Music Making – Sonic Pi, LMMS, AKAI MPK USB MIDI

I am not a musician, not at all. I love music! And for year I feel the craving for being able to make my own music, but have not found the right means for it, yet. Over 30 years ago I started a bit with the guitar and indeed had some fun with it! But it cost a lot of… Read more »

Thinkpad Tablet 10 (TPT10) – Old but Gold :-)

      Kommentare deaktiviert für Thinkpad Tablet 10 (TPT10) – Old but Gold :-)

So, for some reason I dug out my old Thinkpad Tablet 10 again and tried to fire it up. I have to admit I neglected it badly for the past – umpf – maybe thee years? So of course the first thing was that the battery was full flat, it did not even power up. So I let it charge… Read more »

Old Fonera FON2100 – New life

Do you steill remember these tiny Fonera boxes that came up in the early 2000 (maybe 2005 or so)? Fonera started out to create public WiFi infrastructure and you could participate in it by sharing your internet connection with ours – either for free or even earning some money. The routers they used came almost for free so they got… Read more »

CO2 Laser – CW3000 Water Chiller

      Kommentare deaktiviert für CO2 Laser – CW3000 Water Chiller

I just got myself a new toy for the workshop, a water chiller for my 40W laser cutter. Like with pretty much all these laser cutters, it needs water cooling for the CO2 laser tube. Usually they come with an aquarium pump and some silicone tubes you can just throw into a bucket of water. While this is pretty easy… Read more »
