This tutorial shows the construction of an audio knob in reverse. Most important in this tutorial is the use of the array utility that is hidden in the Draft Workbench. Arrays are extremely useful for anything that repeats itself, whether it´s in the X,Y or Z direction, or rotated around an axis in 3D space.

Support me on Patreon! https://www.patreon.com/HoffmanEngineering This is DesignSpark Mechanical, and it is the best free CAD program that I have personally used. Many of the free CAD alternatives are clunky and hard to use, DesignSpark is the first one that truly impressed me. So download it, and give it a try! http://www.rs-online.com/designspark/electronics/eng/page/mechanical I want to know what you guys think about it, let me know in the comments below! -Christopher Hoffman #HoffmanEngineering #3DPrintingHoffman #MakeCoolStuffHoffman #3DPrinting #DIY #FDM #Makers #Making #ResinPrinting #Engineering #Patreon #CAD #3DScanning #Awesome
SSDs have limited program/erase or P/E cycles. In this video I discuss the life expectancy of SLC, eMLC, MLC and TLC drives, as well as covering wear levelling, over provisioning, and TBW, PWB and DWPD endurance ratings. Note that the data presented in this video was obtained from a great many sources, including all major SSD manufacturers, and was up-to-date as of 25 March 2017. Note also that the second SSD listed in the table of client SSDs at c.6:41 is a Samsung 850 Pro, not a Sandisk 850 Pro (which does not exist).

Using currently available tools in FreeCAD to assemble parts. The tools used were Draft Move, Edit Placement, and Edit Alignment. These tools were configured into a custom Toolbar on my Part Workbench for ease of use. As shown, the need of an Assembly Workbench is not necessary to assemble parts in FreeCAD, currently available tools will get the job done.

Sweep and Loft are two tools that can make interesting curvy shapes. I explored them for you in this tutorial. Using them can fully exploit your artistic talents for creating great looking designs.
