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.

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
