More “Pixel Machining” AKA Halftoning Experiments

I first featured an older version of my “Halftoning” or “Pixel-Machining” routine here, then made a pretty successful stencil using this technique.  Lately I’ve been doing some experimentation with varying the diameter of the circle and engraving tiles with it.  See the following video for a time-lapse of me machining a tiger head with a 1 mm endmill.

Besides this tile, I’ve also experimented with some scrap MDF, and have engraved several other tiles after the “Read More.”  Several have been pictures of Err from ATHF, although I did try to do a human portrait with it originally.  This turned out very poorly (I don’t have a picture of it).  Fortunately, Read more »

Wireless Mach3 Control

mach3-androidStefano wrote in recently to share his creation, a wireless interface for Mach3 CNC control software using an Android phone.  Although there doesn’t seem to be acomodation for it (yet) in the app, something like this would be especially useful in conjunction with a webcam or other way to remotely monitor your setup.

A description and installation instructions are available here.  They are written in Stefano’s native Italian.  If you don’t converse in this tongue, you will need to use a translation service.

If you’re curious as to how this works, there’s a video of it in the same place that you can find the instructions.  Unfortunately, I don’t have an Android phone to use this with, but if any of you try this out, please let me know what you think in the comments.
