Enzo wanted pictures of Mark Halpern’s BLAST pivot tester. So, here they are.
It has turnbuckles for grabbing the pivot tabs (on the stator) and holding tension. Currently nothing grabs the rotor, but Pedro is working on that.

The day after the joints arrived we got a big box full of carbon fiber tubes. We waited for Juan to get back from vacation so that he could open them. My self restraint wasn’t strong enough to wait to open the joints. They’re all cut to length and weigh almost nothing. If only we […] Where by “Machine Shop Update” I mean what would have been an update last week if I hadn’t just now discovered that I have these pictures (all from Juan). But the now-not-up-to-date progress shows nearly complete reaction wheel parts and SIP cage. The beginnings of an attitude control system have been integrated with BLASTpol. I’ve been working with Natalie on getting gyroscope readout working and Laura has been working in parallel with the help of Pedro to enable us to command the motors. Mostly, I took these because Giles requested photos of the gondola, and I didn’t […] Unlike the last two, this post is not long-delayed. On Thursday Natalie was assembling the Spider star camera to get a picture of it for her thesis proposal. As a side benefit, I also get pictures of it. And I (among others) get an assembled star camera. I think this is my first post for […] Another overdue post that I just got pictures for today: the SIP cage. Juan designed this cage, which lives at the base of Spider, to hold NASA’s SIP (Standard Instrument Package?), and also to support the reaction wheel. When these photos were taken (almost a month ago) many parts were just tack welded. Now, welding […] A few weeks ago, Barth was actually making cables (for me!). I took a few pictures as proof that it actually happened. Only one turned out well, so I’ve also included a great picture Juan took of Natalie’s solar head bobbing thing. The 50cm jumper/adapter cable Barth made contains about $200 of parts. I still […] So there were a pile of pictures of the DAS (Data Acquisition System) and BLASTbus electronics on my personal camera that I’ve finally gotten around to uploading. There are a lot more than these few I’ve posted, but others probably don’t find them as interesting as I do. I’m biased because I’ve been working on […] So I haven’t written a post for a while, but that’s only because nothing particularly interesting has happened for a while. (That and because there’s some old pictures sitting unloved and unuploaded on my other camera at home.) But interesting stuff is starting to happen again, and this is the beginnings of it. First we […] |
