Description

Cost effective open source imaging (COSI) is a collaborative initiative currently building an affordable low field 

open source MR scanner. COSI Measure is an open source multipurpose 3-axis robot, that can be equipped with field mapping probes for static or dynamic field measurements (electromagnetic, temperature etc.). Submillimeter fidelity and reproducibility/backlash performance were evaluated experimentally. It can be potentially upgraded to be used as a CNC, for 3D printing or other applications, that require reproducible submillimeter movements. The system can be easily scaled to smaller volumes and lighter/cheaper materials (CAD files available).

Part number 1 -- OSEG (Diskussion) 11:06, 13. Apr. 2020 (CEST) Hier konnte ich als OSEG, den Review Status nicht ändern. (Lukas) Re: Part number 1 -- Robert (Diskussion) 14:53, 26. Apr. 2020 (CEST) Ich konntes den Review-Status auch nicht ändern. Wie wird man eigtl. Reviewer, bzw. bin ich schon einer? Part number 1 -- Micha (Diskussion) 23:15, 24. Apr. 2020 (CEST) All technical drawings are inadequate. Things to consider :Symmetry, accuracy of dimensions(decimal place), to many dimensions given(Überbemaßung), dimensioning suitable for production, deminsioning of sinks, details following a norm(DIN, ISO), summarisation of equal features (e.g. 16x M6), missing tolerances and so on. Part number 1 -- Lukas (Diskussion) 23:23, 24. Apr. 2020 (CEST) Assembly Instructions: Upload as PDF as well Steps should have a proper name Tabels too big, pictures too small Hard to review Part number 1 -- Micha (Diskussion) 23:26, 24. Apr. 2020 (CEST) CAD files are missing(stp). Re: Part number 1 -- Robert (Diskussion) 14:55, 26. Apr. 2020 (CEST) Replace this text with your reply I first thought that only the references to the drawings were missing... Both, drawings and references in the BOM should be provided. Part number 1 -- Robert (Diskussion) 14:51, 26. Apr. 2020 (CEST) The links to the vendors are not sufficient to describe the parts. Prices and vendor links are only optional because Once the links become obsolete, the whole documentation is practically useless. Basic information like original drawings or specification for bought parts are needed instead. The same applies to the remaining postitions of this BOM. Part number 1 -- Robert (Diskussion) 15:16, 26. Apr. 2020 (CEST) @Dietrich: The option to delete my comment would be nice. Add Review
