Somehow we banged up the trailer couple so it wouldn't latch nicely. Unfortunately, it was welded rather than bolted to the trailer tongue.  So I cut it off with a cut-off wheel on my angle grinder (being careful to remove more material from the couple than the tongue). It was rusty underneath, so i cleaned it up with a wire wheel   and painted it. The hardest part was drilling 0.5" holes for bolts.  Somehow a cheap bit from a Harbor Freight set of 30 bits worked better than a $17 bit specifically for hard steel.  I think the whole HF set cost less than that one bit.  I kept it pretty oily while drilling for both. I bolted it on with grade 8 (good stuff) bolts and lock nuts. Now we can trailer again!

I'll have a few manly project posts soon (working on a bridge and repairing a trailer), but much of my time is spent on school lately.  I can't post the code (since it could be used by other students and would constitute an honor code violation), but I can show some of the output. A brief summary of the output of our AI assignments (for GaTech's OMSCS CS6601): Assignment 5 On k-means clustering and expectation-maximization.  Required us to do k-means clustering implementation and use it to find ideal "average colors" and the groups of pixels that were closest to those averages.  It is an iterative routine which progressively changes which colors it chooses, and (consequently) which pixels are nearest in color to them. Starting from this image: This is what it looks like with 2 means (2 colors, and the pixels closest to them), then 3 means, 4, 5, and 6. There were some other much trickier pieces, but they were much less visually pleasing. Assignm...

I wanted to install a ceiling fan where there was only a ceiling light.  No problem!  I've done this many times before - maybe 30-45 minutes is plenty. HAHAHAHAHHAHAHAHAHHAA! As so often happens in projects, this one snowballed and wound up taking over 3 hours .  Follow along with these easy-to-repeat steps and see if you can tell where the problem lies: Step 1 - Remove the old light fixture finger screws for the glass bowl -- easy peasy. a screw or two holding the light housing to the junction box --  boy, this box is pretty wiggly. the wirenuts and ground wire connecting the light to the supply --  hot wire is off; all is well. Pro tip: It's a good idea to turn off the breaker, but chances are good your breakers are labeled incomprehensibly or are outright lies.  What I do is turn off the room switch and then quickly tap the hot wire with a finger to see if i get zapped.  I didn't this time! Surprise!  A pleasant surprise!...
