I purchased the iGaging Absolute DRO's from Grizzly and just finished installing them on my Harbor Freight mini mill. They work very well with the included LCD displays and I like the way the displays can be ganged together and mounted easily to the machine.
I also just finished building Yuriy's Launchpad-based Android DRO controller (http://www.yuriystoys.com/2013/07/launchpad-dro-build-instructions.html). The build was very easy and the Bluetooth connection paired easily, but so far I am getting only random flashing numbers on my tablet display. I have been in touch with Yuriy (see link above) and am hoping the problem can be solved and is not a compatibility problem with the Absolute scales.
