GGCGen 1.0.5: A GUI for generation of Opentrons-compatible protocols and lab robot control

I released the software GGCGen   version 1.0.5. GGCGen provides a graphical user interface for the creation of opentrons API version 2.0 (APIv2) compatibe Python scripts (opentrons protocols). The backend pyotronext is used for translation to G-code and robot control , see here for details.  The "opentrons API" for Python by Opentrons Labworks Inc . is an open protocol standard that can be used to control lab robots. One problem of Opentrons original implementation is the tight integration with their hardware and the rest of Opentrons software framework. To overcome this limitation, GGCGen and pyotronext provide a more flexible and customizable framework written in Python that can be easily configured to control any robot that understands G-code (Marlin dialect) using the same protocol standard.

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 .

[Ethymology] Herkunft des Sprichworts "Ich glaube es hackt"

Seit ich als Kind zum ersten mal die Dauerausstellung "Schrift und Zahl" im Heinz-Nixdorf-Museum (Paderborn) sah, bin ich fasziniert von der Entstehung von Sprache und der Herkunft von Worten (Ethymologie). Jetzt bin ich auf einen Onlineartikel gestoßen, in dem diskutiert wird, ob das deutsche Sprichwort "Ich glaube es hackt" nicht besser "Ich glaube es hakt" lauten müsste. Es wird das Wörterbuch der deutschen Umgangssprache (Heinz Küpper 1950) folgendermaßen zitiert: »Ich glaube, es hackt bei dir = du bist wohl nicht recht bei Verstand? Anspielung auf den "Vogel", der im Kopf hackt« Viele Nutzer schreiben in den Kommentaren, dass sie eher der Meinung sind, es müsse eigentlich "Ich glaube es hakt" heißen. Der Nutzer "Joss" erwähnt, dass die Ethymologie des Wortes von Grimm und Grimm gut wiedergegeben wurde und schreibt desweiteren: » "Der Haken" war im in früheren Zeiten auch "der Hacken" (trotzde...

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.

Get rid of your kilos in less than 4 months?!

Are you worried about gaining some extra kilos during Christmas time? Then you may be pleased to read that your old kilograms will be gone in no time. In fact, exactly on 19th May 2019 all kilograms in the whole universe will be gone "PUFF"... and they will be replaced by brand new, much better kilograms! WOW!  That is because the 26th General Conference on Weights and Measures revised the International System of Units in order to derive all SI base units from natural constants. So the kilogram is no longer defined as the mass of the International Prototype Kilogram. The new definition of the kilogram is rather: The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1 , where the metre and the second are defined in terms of the speed of light and the caesium frequency .   I'm sure you lost at least two kilo...

DerAndere goes Gitlab

Hey folks,  In order to make my blog more readable and at the same time make the source code more accessible to developers and profit from version control, I removed a lot of raw-code from the pages of this blog and made the step to use public repositories on https://gitlab.com . I am currently maintaining two Gitlab groups: https://gitlab.com/RobotsByDerAndere and https://gitlab.com/DataAnalysisByDerAndere . I also changed some of the used libraries, so most of my projects on Gitlab are now open source under the terms of the permissive MIT License!

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.
