The rest of my 80/20 arrived at John Henry Foster and I picked it up. The X-axis is aligned and slides easily and smoothly by hand. So I tightened down the acme nut and bearing blocks at each end and chucked an inch of 1/4" rod in my drill to try it out. Really difficult to not put the remaining parts and electronics on credit cards now.
DiscountSteel.com had my rails cut and ready within 24 hours and I picked them up at lunch. Carefully scratched 32.7mm from the good edge with a woodscrew about every 4in. Then a tap with the transfer punch, check, and a good hit with the transfer punch.
My first departure was a learning experience but is over. The cost of good motors and the gecko controller call for a machine with commensurate capabilities to be worthwhile. Fine Line Automation offers a popular kit called FLA-100 and posts free plans for the machine on their website. I decided to save for the entire kit and electronics. Then ABC Electronics got in a good load of 80/20 and my willpower gave out.
The Android SDK comes with a SampleSyncAdapter project for implementing a synced connection to a cloud-type service. The class NetworkUtilities takes care of making the actual HTTP requests, and generally has to be tailored to work with a particular cloud service (apart from the sample server app included with the SDK).
Here is a base class that handles the session-based authentication for Drupal’s JSON Server module. Extend this class to implement the calls for a particular service model via Drupal / JSON Server.
Building a view to support iPad and iPhone is a little clunky. Apple suggests that separate UIViewController’s be built, one for each device. But the vast majority of ViewControllers will want to implement the same logic whether being run on iPad or iPhone. For instance, say my view shows an image and presents a text box and a button. The ViewController needs to respond to the button by doing something with the text in the text box. This functionality is exactly the same no matter the device.
Some great christmas presents need a home close to my electronics bench in the laundry room. I justified my bandsaw and planer purchases by reasoning that I would be able to build useful things from cheap pine lumber. This shelf verifies the possibility.
I raised the attic floor with a 2x8 frame and blew in cellulose insulation. Master insulation machine operator Jay Manke loaded the bales down in front. The cellulose is extremely dusty and difficult to contain.
