CNC Panel Joinery Notebook
I’ve been collecting clever ways of slotting flat stock together since I first read Nomadic Furniture back in 1999, well before the advent of the accessible hobby-class CNC tools that today make manufacturing parts like these pretty easy. Now, the world is full of people designing models, project enclosures, sculpture, furniture, and all kinds of other cool stuff to be assembled from parts made on laser cutters and CNC routers. I keep expecting a definitive book or website to emerge that covers the “bag of tricks” in an organized way, but so far, I haven’t found it. Maybe this article can serve as a jumping-off point. In any case, I think it’s time to share my notebook of CNC panel joinery. In presenting this material, I want to first acknowledge my respect for the world’s established and ancient traditions of joinery. I may abuse some terms, without meaning to, and I am glad to be corrected by those who are in the know about traditional joinery. Laser vs. Biasing Cross (“X”) Joints

Lite6 - A high quality, low cost HotEnd for everyone
Posted On: 2015-04-01 13:32:47 ; Read: 403 time(s) Introduction We know that not everybody needs the all-metal high-temperature performance of an E3D-v6. We’ve come to realise that there exists a need for a hotend that is reliable, and puts out great prints, but meets the budget of those who are just getting started in 3D printing. Lite6 is our answer to that need. Lite6 Assembled Lite6 does not supersede v6 - more compliments it, think of Lite6 as v6’s little brother. E3D-Lite6 v.s E3D-v6 Features: Aimed at printing everyday materials. Lite6 cannot offer the same high-temperature performance as E3D-v6, which means that you can’t print higher-performance engineering plastics like Nylon, Polycarbonate, and ColorFabb Carbon-Fiber XT. Some nice E3D-Lite6 prints in PLA and ABS Lite6 has a slightly shorter effective melt-zone than v6, which does mean that print speeds are more modest, but still completely appropriate for all but the very fastest of 3D printers on the market. Exceptional Reliability
Education Theory/Constructivism and Social Constructivism - UCD - CTAG
"Constructivism is the philosophical and scientific position that knowledge arises through a process of active construction."(Mascolol & Fischer, 2005) "As long as there were people asking each other questions, we have had constructivist classrooms. Constructivism, the study of learning, is about how we all make sense of our world, and that really hasn’t changed."(Brooks, 1999) Background Constructivism and Social Constructivism are two similar learning theories which share a large number of underlying assumptions, and an interpretive epistemological position. Underlying Assumptions Jonassen (1994) proposed that there are eight characteristics that underline the constructivist learning environments and are applicable to both perspectives: Constructivist learning environments provide multiple representations of reality. Epistemology The default epistemology in education is an empirical/reductionist approach to teaching and learning. Main Theorists Dewey Piaget Bruner Vygotsky According to Vygotsky:

About Gear Generator is a tool for creating involute spur gears and download them in DXF or SVG format. Why this tool was created? Support: abel@iparigrafika.hu Notes about browser compatibility: all new major browsers are supported (i didn't tested IE), but unfortunately Chrome can't render SVG circle correctly. The downloaded DXF file can be opened with AutoCad 2013 or newer versions. Update 1.5: Fixed DXF resolution issue. Update 1.4: TA-DA: Added internal gear support, and the ability of positioning the first gear. Update 1.3: Fixed DXF file format. On YouTube Check out other tools I made:Print Charts, Flip.World, HTML Spirograph.
