Nirav Patel looks like he likes to play with some diverse toys and has shared much at his blog. Lately it seems he’s taken to 3D printing and offers a some useful tidbits in Physical Keygen: Duplicating House Keys on a 3D Printer. Also, WeatherSpark.com is something I’ve been looking for a long time. […]

Geo01005’s RepRap Ideas details some of his work around running a repstrap using EMC2 from a couple years ago. He’s documented some of his work around the hot-He also has a YouTube channel. Andrew Angellotti is founder of spingarage LLC has a new blog that’s looking pretty interesting. Here’s the first part of a tutorial […]
So again I wanted to work on putting together the next piece in the EMC2 Servo lab series tonight only to thwart myself. I shot a bunch of pictures last night with my newly rehabilitated camera. When I sat down today my iPhoto library was kinda corrupted so I decided to rebuild it. Well right […]
Based on the venerable L298 Dual H-Bridge , Solarbotics has put together a really nice little kit for low-mid voltage level motor control applications. You trade a little sweat equity for the few bucks you save over other offerings by fully assembling the kit yourself. One of the nice bits about this kit is that […]
Well I’d planned on spending the evening snapping pics and scratching out the next part in the inkjet and servo lab series, but when I pulled my trusty Olympus SP-350 out of the backpack, I discovered it made some odd grinding noises, extended and retracted the lens a couple times eventually displaying “Zoom Error” on the screen. ARGH!!!
EMC2 is a popular choice among hobbyists, academics and a growing group of professionals for CNC and robotic machine control. Most commonly it seems to be used to drive machines using stepper motors for reasons related to low cost and complexity. In actuality EMC2 drives servo mechanisms equally well, but in doing my research in preparation for my own projects I found that there was a need for a simple tutorial laying out basic procedures for integrating servo control under EMC2. As always, the very best way to learn is to do so I ended up playing with a small servo “lab” so I could visit as many concepts and parameters as I could before applying them to a larger machine.

One of the things I need to do while working towards motion control projects is to practice some of the fundamentals. I’ve worked with many of the concepts and mechanisms professionally, but more from the support end. I haven’t touched the stuff for a few years now, and want to learn things at a more […]
Some links that have turned up while doing research: Musings on the usefulness of inkjet printers for a variety of applications. So ok, I’m not the only one who’s been thinking about this, but here I hope to actually do something about it! Anders is playing with EMC2 and RepRap functionality as well. I’ve experimented […]
Background I started playing with EMC on a simple home-build concept mill I built about 9 years ago and it’s been shelved for most of the time since. I really enjoyed the experience of getting that to work and have followed several other software/hardware projects online since including EMC2 and the RepRap/Makerbot crowd with great […]
