      Kommentare deaktiviert für Ultra portable mini soldering iron – Even open source

I just wanted to quickly share my excitement about a device I purchased some time ago – the TS100 mini soldering iron. The TS100 is a really tiny soldering iron, and light weight. With the tip assembled it is overall about 17cm long and weighs just a little over 30gr. The manufacturer also offers a range of replaceable tips for… Read more »

Recently I got myself a new toy, which is actually a very useful toy, a thermal camera! The one I got was used from eBay, a FLIR ONE Pro “for Android” with USB type-C connector, this is how it looks like: This is a pretty neat device as it attaches directly to the USB type–C port of a mobile phone… Read more »

Power Cosumption – Intel Based Laptops

      Kommentare deaktiviert für Power Cosumption – Intel Based Laptops

With the Teclast F5 (same hardware: BMAX Y11) being my portable little workstation I try to maximize battery life under Linux as much as I can and while doing that try to figure out which are high consumers and how to bring these down. One of the very first things I found useful was to run powertop and going to… Read more »

Teclast F5 – Update

      Kommentare deaktiviert für Teclast F5 – Update

Some time ago I wrote a review of my experiences with the Teclast F5 11.6″ slim laptop and Linux. I am still a fan of this low cost but super slim and light weight laptop. It offers everything I need as an ultra mobile laptop for travel – 8GB RAM, M.2 SATA SSD slot, full-HD display and even touch. It… Read more »

After some silence and in preparation for CCC Camp 2019 where I want to use this board as small FTP server I updated the kernel a bit to 3.16.72 (LTS), information here: https://www.warpcomm.org/ and patch here: https://www.warpcomm.org/downloads/tk71/20190815/linux-3.16.72-tk71.patch Maybe some time in the future I’ll forward port the stuff to 4.x or 5.x but this is a bit more effort since… Read more »

      Kommentare deaktiviert für China 40W Laser Cutter / Engraver – You get what you pay for :-)

So, this is the latest addition to my workshop, a _really_ cheap 40W CO2 laser cutter / engraver I got new from eBay for 315EUR – including shipping! For that price you can not expect miracles. Why I did it anyway, being perfectly aware of the possible issues, was that I wanted to play around with laser cutting and especially… Read more »

Teclast F5 – 11.6″ Laptop & Linux

      6 Kommentare zu Teclast F5 – 11.6″ Laptop & Linux

Last week I was in Hong Kong and shopped a bit for electronics. I love small laptops since I am traveling quite a bit lately and don’t want to carry around too much weight and bulky luggage but still want to be able to do the basic things – some programming, office, web browsing. The current 13″ laptops are already… Read more »

CNC free software – resurrection of legacy mill

Back in the days when PCB making was expensive I started to look at ways to do that on my own. There were basically two: photo lithography and etching or milling. I did not like the idea of having to handle the nasty chemicals for etching so I first decided to get myself a CNC milling machine. Later on I… Read more »

Some may already be aware of it, since September 2016 I am member of the Purism Advisory Board and consulting Purism in matters of mobile devices. As development continues I have been asked beginning of 2017 if I could imagine to lead a mobile device development. After some further discussion about possibilities I started to lead a mobile device development… Read more »
