Too Many Sketches

Added on by Spencer Wright.

I've been working on optimizing the Topper a bit, which has involved starting from scratch and remodeling the loft a little smarter. 

...But it's getting complicated. There's *way* too much here, and this is a stripped down version of what I had last night. 

Basically, NURBS surfaces kinda suck - building this loft is a PITA. I would try this in Fusion 360 with T-splines... but I'm hesitant. Last week's version was pretty close to where I wanted it, and I thought that I could rebuild it quickly and move on. My work this morning will tell whether I was wrong.

More T-Splines

This is pretty fun. The first shot is of the control frame view; the second is smoothed - which is how the part would be produced. 

I'm new at T-spline modeling, and have a few issues with this model. Nonetheless, it's basically ready to be converted into a mechanical assembly. There, it would be split into a frame and arms; hinges would be installed; lens features would be designed. 

Pretty fun.

Progress: The Public Radio

Added on by Spencer Wright.

Last night, Zach and I bribed Todd to help us jumpstart The Public Radio a bit. When we last worked on it, we had a short on the 3.3v line that we couldn't find. Well, that was fixed in short order, and we also were able to diagnose & fix a few other issues that we weren't aware of. 

We left with a board that's still not quite ready, but it's getting a lot closer. We also had a few more thoughts about how we should be proceeding, and it seems likely that they'll brew into something more actionable in the coming weeks.

It seems likely that with another day's work, we could get this board tuned up and blasting HOT97 like it should be. At that point, though, we need to undertake a total redesign of the whole assembly. The PCB is the wrong size & shape; the speaker is too large; the potentiometer isn't long enough; the lid is the wrong thickness (and, ultimately, the wrong material). 

It's also seeming likely that we end up redesigning the radio to be a simpler (and possibly analog) device... but that will only happen further down the line.

When I was younger

I built this frame in 2008. It was the first belt drive bike I built, and hence it was an experiment that I financed on my nonexistent R&D budget. I probably spent $2500 on it, plus something like 40 hours of build time.  But that paled in comparison to the time I spent *thinking* about it, which was likely in the 80 hour range. I also developed the graphic design myself, teaching myself Illustrator in the process - add another 20-30 hours there.  

I like the bike. It was a pain in the ass, a challenge. I tested out a bunch of new things on it - the S&S seatstay coupling, a new waterjet head tube badge, a new (fancy) paint job with painted-on graphics. I think it came out great, though paint isn't exactly notable for its durability, and now the frame - despite being woefully underused - is chipped and scratched in all manner of places. 

Regardless, I love it. I don't know what I thought I was doing, but I fucking took this bike on, and I'm proud of myself that the project being a bit over my head - and over my budget - didn't stop me.

I know it's hard to tell, but this is Chris, engraving some parts on my old pantograph in early 2010.   

I like dark photos :) 

Parts

Added on by Spencer Wright.

I took these photos in 2009, and meant to do something with them for a long time.  

The seat lug remains unused, though I'd like to change that. The stem went on Ian's bike. The hand vise is actually very handy, though career shifts mean that I don't use it often anymore. 

Cold

My old shop. Truckee, CA, 2007.  It was too small with the door closed to move around, and anyway it was unheated, so I would open it up and revel in the abject humor of the whole thing. I thought this photo (which I orchestrated with a tripod, etc.) was hilarious. 

I want this bike back.

That Transitional Time

Working on a way to determine whether your boat's anchor line has been severed. Kinda tricky.

Working on being happy.

Jersey City. 

Russo Mozzarella & Pasta.

Leather. And stuff.

I ended up rebuilding this model twice. This is the second shot at it, but I'm far from done here.

At this point I've got most of the structure modeled, but am missing a surface stitch or two - at which point the surfaces all come together to form a solid. This is getting close.

 :phew: 

This is way more than I needed, but it was a good challenge. I'd like to think I learned a lot. 

Pre ride.

 Todd's shit.

Lunch with Zach.

Zach's idea. There's more to this... hopefully this week.
