pyotronext 1.0.5: Convert opentrons protocols to G-code and control lab robots made from 3D printer

I released the software pyotronext version 1.0.5. pyotronext can interpret opentrons protocols and control lab robots (e.g. DIY cartesian pipetting robots made from a 3D-Printer). Opentrons Labworks Inc. develops the open source opentrons API version 2.0 (APIv2) as well as a tool to convert JSON files that have a similar format as Transcriptic's Autoprotocol standard. The opentrons Python APIv2 allows easy and flexible scripting. Using the Python package pyotronext, you can run Python scripts that use the opentrons APIv2 and send G-code to a lab robot that runs my modified Marlin firmware ( Marlin2ForPipetBot ). pyotronext can also export the generated G-code to file. pyotronext serves as a backend for my Graphical G-code Generator and robot control software GGCGen .  Copyright (c) 2020 DerAndere

Scalable knitting patterns with open source software: Textile design with Inkscape and GIMP.

I made a video tutorial that explains how to design knitting patterns that can be scaled to arbitrary size using the open source programs Inkscape v0.92 and  GIMP 2.10.10 . It may be especially interesting to the community of the All Yarns are Beautiful (AYAB) project . This page was moved to https://derandere.gitlab.io/scalable-knitting-patterns-inkscape .

Demonstration of the lab robot "PipetBot-A8" by DerAndere.

I am proudly presenting a working prototype of my pipetting robot "PipetBot-A8".  Of course it is an ongoing project and there are many things to improve, but the device is doing what I want and its precision is already quite good. Here is a link to the video . After I finally managed to fix most issues with my robot control software GGCGen, it is ready for testing. I uploaded an introductory video that showcases the Graphical G-code Generator . Visit the page "PipetBot-A8" on this blog for details. Brought to you by DerAndere.

Gimp makes progress, but Krita and Darktable get it right.

GIMP 2.10.6 introduces vertical text layers and comes with improved performance. Recently, the GNOME foundation received a 400,000 $ donation and they sent a quarter of that money to GIMP. Hopefully this financial support will help to finally make GIMP useable in a productive environment. Currently, color management is still broken. But the space invasion project made the underlying General Graphical Library (GEGL) fully color-managed and the developers of GIMP try to make use of this and make GIMP fully color managed, too. This development takes place in the GIMP 2.99 development version ( git master branch of GNOME/gimp). For the time being, stick to the second big open-source image manipulation software, Krita , whenever possible (the text tool needs to be overhauled). Krita 4.11 has support for Python 3 scripting, vector, filter, group, and file layers. You can nondestructively work on layers with masks. Krita supports full color management through LCMS for ICC and OpenColor IO fo...

Gimp 2.10.0 released. The open-source competitor of Adobe Photoshop

Finally, the GNU Image Manipulating Program (GIMP) 2.10.0 has been released. The open source software GIMP can now be considered for productive work and makes professional image manipulation available for everyone. It supports high bit depth (up to 32 bit precision) and color management. Most importantly, GIMP now gives access to radiometrically correct adjustment of contrast / levels / curves, color mixing and blending ( these operations have to be performed in a linear working space , i.e. in a color working space which has a tone reproduction curve with a gamma of 1.0 at all densities). GIMP is cross-platform software which means it is available for Microsoft Windows, Linux and Apple iOS. In my oppinion, this achievement is worth a donation to the developers by every user of GIMP. GIMP can now be regarded as a serious competitor for Adobe Photoshop.

Zyn-Fusion open-source synthesizer

Great news: The source-code for the synthesizer Zyn-Fusion was published. Now it can be built from source as explained on my blog on the page "music". Zyn-Fusion is the latest version of the powerful synthesizer ZynAddSubFX with the modernized graphical user interface " Fusion" . It works as a stand-alone as well as a VST-plug-in.

GIMP 2.10 Release candidate 1 available

Finally, the GNU Image Manipulating Program (GIMP) 2.10 release candidate 1 is available for Linux as well as for the 64 bit version of Microsoft Windows. It is the first time, the open source software GIMP can be used for serious, professional image manipulation. It supports high bit depth (up to 32 bit precision) and color management. Most importantly, this is the first time GIMP gives access to radiometrically correct adjustment of contrast / levels / curves, color mixing and blending ( these operations have to be performed in a linear working space , i.e. in a color working space which has a tone reproduction curve with a gamma of 1.0 at all densities). Only few problems remain to be solved, before GIMP 2.10 can be officially released as stable.
