https://www.okob.net/wp Notes, ideas and general comments on anything related to high-tech. Mon, 12 Aug 2024 03:04:35 +0000 http://backend.userland.com/rss092 en I planted a few fruit trees 7-8 years ago (I'm in NH). The results so far: Apricot - died, never seen a single apricot. Asian pear - produced for a couple years, but almost dead now (looks like the statue of liberty - copper oxide color). Cherry (bitter one) - doing ok, usually lots ... https://www.okob.net/wp/index.php/2024/08/11/peaches-getting-destroyed-before-harvesting-brown-rot/ The new fashion of having borderless windows is quite annoying (struggled with that under both MS Win 10 and Ubuntu). Here's the solution for Ubuntu (combined from a couple posts on stack overflow)... First make "~/.config/gtk-3.0/gtk.css" with the following content: decoration { border: 1px solid gray; background: gray; } Second paste this into ... https://www.okob.net/wp/index.php/2021/07/30/adding-borders-to-terminal-windows-under-ubuntu-1804/ I had to start using nedit under Ubuntu 18.04.5 in VirtualBox under Win 10 and unfortunately encountered an intermittent problem with the keyboard input stopping to work (see post here: https://www.okob.net/wp/index.php/2021/07/30/building-nedit-ng-for-ubuntu-1804/). After trying to use nedit-ng for a bit I decided to switch back and try to solve that keyboard input ... https://www.okob.net/wp/index.php/2021/07/30/keyboard-input-problem-with-nedit-under-ubuntu-1804-in-virtual-box/ I had to start using nedit under Ubuntu 18.04.5 in VirtualBox under Win 10. NEdit 5.7 that came with Ubuntu 18.04 and the binary that was perfectly stable under 16.04 (under ESXi) were both getting into state when the keyboard input wasn't working (but Ctrl+ and functional keys still did). I decided ... https://www.okob.net/wp/index.php/2021/07/30/building-nedit-ng-for-ubuntu-1804/ This simple contraption was quickly put together a few years ago to allow remote power control over WiFi or USB dongle. It can be set up to work as a WiFi access point serving its own SSID or as a client connecting to an existent WiFi network. In order to ... https://www.okob.net/wp/index.php/2020/11/28/converting-old-ups-to-power-control-box/ I retrofitted a couple old UPS boxes with external battery packs that provide more runtime, but I do not trust those UPS devices to calculate the remaining charge to decide when it's time to shut down. I needed to set explicitly how much time I want the system to run ... https://www.okob.net/wp/index.php/2020/11/27/cyberpower-powerpanel-personal-edition-settings/ Wow, that was exciting... My Samsung S9 battery bloated up popping the back cover open. I bought a replacement and was in the process of changing it when the old (bloated one) shorted somewhere inside in the bottom corner of the battery. It started by glowing in one small point then ... https://www.okob.net/wp/index.php/2020/08/08/first-hand-experience-with-samsung-galaxy-s9-battery-getting-on-fire/ For my first experimental print the nozzle temperature was 250C. That appeared to be the right temperature for printing, but a bit too high for the hotend. It looked like decreasing the temperature a little was possible. The further experiments proved that printing it at 245C works perfectly fine. The bed ... https://www.okob.net/wp/index.php/2018/12/15/printing-alloy-910-from-taulman3dcom/ The material prints nicely. It flows and leaves strings like PLA though (perhaps increasing retraction a bit will help). I used the same slicer settings as for their (http://taulman3d.com) Nvent filament (didn't play with any settings to make it more transparent). The extruder was at 245C although I think it could ... https://www.okob.net/wp/index.php/2018/12/02/printing-t-glase-clear-filament/ Long story short, I needed to source about 20lb of lead cheaply and decided to take apart an old car-sized marine battery a friend gave me. If you ever do that (and my advice don't) just get the contact points and the big chunks that bridge the plates. You can see ... https://www.okob.net/wp/index.php/2018/10/04/how-much-lead-can-you-get-from-a-car-battery/
