Sportys practice written IFR test

Just took the Sporty's free practice IFR written test exam and got a 92/100. It went really quick, took about 30 minutes to do the 60 questions.

I didn't get any lengthy questions though, so that's probably why (the questions are chosen randomly from a set of many 100).

I studied by going through the Jeppesen study guide - it was pretty nice but it was very painful to slip through the book to find charts (the charts are not always beside the question).

If I had to do it again, I can't decide if I'd go with the book or with the electronic version. I was initially turned off by the fact that the web site study guide was on a subscription basis, but a this point, I don't think that would have been a problem for me.

A-10C Standby Compass - Sun Shade

Image
 One of the final items to add to this instrument build (besides the text covers for the lower LEDs) was the sun shade for the AR LED box.  I made this out of thin aluminum sheets , cutting it from a template using some metal sheers .    My template was created by tracing some of the actual artwork from the DCS sim, and then scaling it to the proper size. It turned out ok, not perfect but pretty good.  Primed and painted it and then installed it using 2 of the 4 holes that were already on the LED box 3D print.  I used some heat inserts in those holes to give the screws something to bite, but the holes are really too big for my inserts so had to use some glue to help out.

A10-C Standby Compass: Final Setup

Image
Got everything soldered together (after likely damaging one EasyDriver and moving to a backup) and squeezed it into the case.  At first I thought the compass wheel was much too high but then I realized the front bezel was installed upside down. Used an Exacto knife to cut a piece of acrylic for the front glass and put a small vertical sticker on it to act as the reference line.  Not super pretty but works ok until I can cut with a laser instead (maybe an xTool). Getting everything to fit was trickier than I expected, but it all worked out without too much rework required.  I used some 5.5mm x 2.1mm plugs for the 12v power plugs (tip/center was positive).   For the aerial refueling LEDs I used some more LEDs that have resistors built-in.  They are made for 12v so will likely bit a little dim since I am powering them off the digital out 5v pins from the Nano.  Don't have a way to make the lens for those yet so will wait to see if that is the case.  ...
