CAD for VEX Robotics
CAD for VEX Robotics (updated 7/23/20) The question of CAD comes up from time to time, so here is some information and sources you can use to help you and your students get started with CAD. “COMPUTER AIDED DESIGN” OR “COMPUTER AIDED DOCUMENTATION”? First off, the nature of VEX in general, is a highly versatile prototyping system, and this leads to “tinkerbots” (for good or bad, how many robots are truly planned out down to the specific parts prior to building?). The team that actually uses CAD for design (that is, CAD is done before building), will usually be an advanced high school team, juniors or seniors (and VEX-U teams, of course), and they will still likely use CAD only for preliminary design, then future mods and improvements will be tinkered onto the original design. The exception is 3d printed parts (U-teams only, for now) which obviously have to be designed in CAD. I will say that I’m seeing an encouraging trend that more students are looking to CAD design than in the past. One thing that has helped is that computers don’t need to be so powerful and expensive to run some of the newer CAD software…especially OnShape. Here’s some reality: most VEX people look at CAD to document their design and create neat looking renderings of their robots. If you don't have the time to learn CAD, I suggest taking pictures. Seriously though, CAD stands for Computer Aided Design, not Computer Aided Documentation. It takes time to learn, which is why community colleges have 2-year degrees in CAD, or you can take weeks of training (paid for by your employer, of course). -

Experiences in Using Open Source Software for Teaching Electronic Engineering CAD
Experiences in Using Open Source Software for Teaching Electronic Engineering CAD Dr Simon Busbridge1 & Dr Deshinder Singh Gill School of Computing, Engineering and Mathematics, University of Brighton, Brighton BN2 4GJ [email protected] Abstract Embedded systems and simulation distinguish modern professional electronic engineering from that learnt at school. First year undergraduates typically have little appreciation of engineering software capabilities and file handling beyond elementary word processing. This year we expedited blended teaching through the experiential based learning process via open source engineering software. Students engaged with the entire electronic engineering product creation process from inception, performance simulation, printed circuit board design, manufacture and assembly, to cabinet design and complete finished product. Currently students learn software skills using a mixture of electronic and mechanical engineering software packages. Although these have professional capability they are not available off-campus and are sometimes surprisingly poor in simulating real world devices. In this paper we report use of LTspice, FreePCB and OpenSCAD for the learning and teaching of analogue electronics simulation and manufacture. Comparison of the software options, the type of tasks undertaken, examples of student assignments and outputs, and learning achieved are presented. Examples of assignment based learning, integration between the open source packages and difficulties encountered are discussed. Evaluation of student attitudes and responses to this method of learning and teaching are also discussed, and the educational advantages of using this approach compared to the use of commercial packages is highlighted. Introduction Most educational establishments use software for simulating or designing engineering. Most commercial packages come with an academic licence which restricts access to on-site computers. -

Index Introduction OpenSCAD is a software for creating solid 3D CAD objects. It is free software (http://www.gnu.org/philosophy/free-sw.html) and available for GNU/Linux (http://www.gnu.org/) , MS Windows and Apple OS X. Unlike most free software for creating 3D models (such as the well-known application Blender (http://www.blender.org/) ), OpenSCAD does not focus on the artistic aspects of 3D modelling, but instead focuses on the CAD aspects. So it might be the application you are looking for when you are planning to create 3D models of machine parts, but probably is not what you are looking for when you are more interested in creating computer- animated movies. OpenSCAD is not an interactive modeller. -
Programming Resume
Thomas John Hastings Programming Resume Introduction: I am a highly motivated self-starter with a passion for problem solving. As the owner of a thriving entertainment agency, Big Top Entertainment, I used coding as a way to automate and improve our business processes. I also designed, built and programmed my own unique performance equipment. Since the pandemic and recurring lockdowns have put live entertainment on hold, I have repurposed my passion for programming into a full time focus. I am looking for a challenge, to be involved in building something, learning new technology and sharing the knowledge I have gained from my own projects. Programming – languages and frameworks: Processing I have extensive knowledge of this Java-based creative programming language. The great thing about Processing is the way you can deploy to Desktop, Mobile, and Cloud with only a few modifications to the same code base. Android (Java) I have seven Android apps published to the Google Play Store, five of which are written in Java. I have developed many more for personal use, including the most recent, CoronaVirusSA, an open source app which graphs reliable stats on the COVID-19 outbreak in South Africa. JavaScript Anyone developing for the web needs to know JavaScript. I am familiar with the Flask back end with Jinja, Bootstrap, JQuery, as well as the excellent Tabulator library for tables. Currently (2020/21) my free time is spent on a couple of entertainment related side projects using this stack. Linux I have been using Ubuntu as my main computing system for over 10 years, both in the cloud (DigitalOcean) and on my Laptop. -
Development of a Coupling Approach for Multi-Physics Analyses of Fusion Reactors
Development of a coupling approach for multi-physics analyses of fusion reactors Zur Erlangung des akademischen Grades eines Doktors der Ingenieurwissenschaften (Dr.-Ing.) bei der Fakultat¨ fur¨ Maschinenbau des Karlsruher Instituts fur¨ Technologie (KIT) genehmigte DISSERTATION von Yuefeng Qiu Datum der mundlichen¨ Prufung:¨ 12. 05. 2016 Referent: Prof. Dr. Stieglitz Korreferent: Prof. Dr. Moslang¨ This document is licensed under the Creative Commons Attribution – Share Alike 3.0 DE License (CC BY-SA 3.0 DE): http://creativecommons.org/licenses/by-sa/3.0/de/ Abstract Fusion reactors are complex systems which are built of many complex components and sub-systems with irregular geometries. Their design involves many interdependent multi- physics problems which require coupled neutronic, thermal hydraulic (TH) and structural mechanical (SM) analyses. In this work, an integrated system has been developed to achieve coupled multi-physics analyses of complex fusion reactor systems. An advanced Monte Carlo (MC) modeling approach has been first developed for converting complex models to MC models with hybrid constructive solid and unstructured mesh geometries. A Tessellation-Tetrahedralization approach has been proposed for generating accurate and efficient unstructured meshes for describing MC models. For coupled multi-physics analyses, a high-fidelity coupling approach has been developed for the physical conservative data mapping from MC meshes to TH and SM meshes. Interfaces have been implemented for the MC codes MCNP5/6, TRIPOLI-4 and Geant4, the CFD codes CFX and Fluent, and the FE analysis platform ANSYS Workbench. Furthermore, these approaches have been implemented and integrated into the SALOME simulation platform. Therefore, a coupling system has been developed, which covers the entire analysis cycle of CAD design, neutronic, TH and SM analyses. -
