“Two great corrugated-jello-head surfaces that mentate great together!” Hmm, ok, not the most catchy slogan ever devised. Another reason I don’t work in marketing.
TechShop open house today was great. Did a bunch more scanning of stuff from my old notebooks that either I never built or that I want to build again, but better this time. Hopped into the CNC Level 3 class, ShopBot, even though (ssh!) I haven’t had Level 1 yet. But since I signed up for it this Tuesday, it will all go together in my head, like peanut butter and chocolate. The instructor, Matt, was awesome. The classmates were awesome. In fact, we all talked so much about so many cool things that sometimes we had to drag ourselves, collectively, back into Class Mode. Machining, modeling, keyline permaculture, solar refrigerators that use wax as a liquid to run a compressor, the insanely cool LightScribe pen and notebook set (with audio!) that one classmate was using to take notes with, polarizing fresnel lenses to optimize solar power transfer while minimizing heat takeup, and more, way more.
The trouble with coming home from TechShop is that my brain is still exploding long after I get home. If it’s late, like now, I have to do something to wind down, like, um, hey! Back up the scans from my USB drive, and maybe blog a little. After the ShopBot class I tried to put my new knowledge to use but got bogged down in stuff that isn’t covered in the class, like how to get my scanned line art into a form that Cut2D will like. For some reason, Gimp pulled in my scanned file as Indexed Layers which I couldn’t find a way to compress, so I couldn’t use Threshold to clean up the image from the scanned Black & White Drawing Form. I pulled the .bmp into Corel Draw instead, and was able to get what looked like decent line-art by using the Hair-thin transform. Alas, saved as a .dxf and pulled into Cut2D, I had two different sets of vectors, which partially overlapped, and a weird edge case that turned out to be parsed as a line, rather than as a toolpath. Bah. Gave up at a little after 11pm, but will be BACK AGAIN. 😉 I have So. Much. Art. Fortunately a lot of it is already scanned at 300 or even 600 dpi. I just have to learn to convert it correctly.

One of many bits of line art accumulated over years of drawing; this one in particular I'd like to make as cutout art and inlay translucent plastic or glass into.
Yes, but where’s the epistemology, I hear you say. Ah, that is the following diagram, which I rediscovered when going through one of my old notebooks that I brought to scan things from. I stayed up late a few nights with a friend in 1991 and was doing a lot of reading at the time about knowledge representation, NLP, metaprogramming, etc. This diagram was my attempt at creating something of a Unified Field Theory of the stuff I was studying (informally) at the time. I think it would take me at least an hour to explain it, probably two. I compressed a lot of info in there. Some of it may be BS, but some of it may be compression loss for those who don’t have the reconstruction set. Commentary welcome, flames less so. 😉
Like anyone will actually spend precious heartbeats puzzling over this diagram! Ah, the blogosphere, where all vanity is made manifest. 😀 But my brain has stopped whirring quite so noisily, and now I can go to sleep. Tomorrow: Farmer’s Market, Sunnyvale Art & Wine Fest, and I really need to transplant those Tiger’s Eye bean seedlings… AFTER I put up snail fencing.
