Lots Of Links

Here are a lot of links I think are relevant to open hardware. The first is that apparently RepRap has its own magazine now!

Zero Cost Modeling of Space Frames – Julian Edgar demonstrates how to predict the failure mode of a complex frame (in this case a recumbent bicycle) without FEA software. The process involves making a scale model by soldering together copper wire then pulling on it to see where it bends or breaks. It’s a quick and easy way to see where the structure is mathematically weak.

XYZ SpaceFrame Vehicles – This is a principle for building modular bicycles and a few functional real-world examples. Here’s a pdf describing how to make one of the bicycles.

Open Source Government & Engaged Citizens: The Death Star Inspiration – Matt Micene writes, “Innovation doesn’t always result in direct business value, but can improve business in general. Innovating in the open means you can garner additional expertise you need to transform a marginal value into a direct value.”

A Guide For 3D Printing With a RepRap – ArvidJense has put together an infographic to help makers build things, specifically musical instruments, but the ideas can be applied to anything.

Someone Needs To Buy Makerbot Already – Steve Symington is talking about financial investment stuffs, but the interesting thing is that Makerbot only seems to have attracted serious financial interest after (or based on the promise of) abandoning open source principles.

Party Robotics – They are a startup focused on making open source drink mixing machines.

Using OpenSCAD for 2D Machining – Matthew Venn gives a brief overview of his process for modeling a multi-piece part in OpenSCAD and then using the projection() function to export DXFs for CNC milling.

Designing For Laser Cutting In OpenSCAD – This is a similar (but more extensive) set of instructions from a Dutch FabLab.

Make Your Own Arduino – streetjerk shows you how to put together a thru-hole Arduino from raw materials. This is particularly useful if, like streetjerk, you want to incorporate additional components (like a motor driver) into the board itself rather than use I/O ports.

Prepper Movement Embracing 3D Printing – PosserteusMaximus has compiled a list of links on how the preppers/survivalist community is becoming aware of, using and contributing to open hardware and 3D printing.
