... so, I guess this past !gravmass ended up teaching us a little about chemistry in addition to physics ☺ -

Estes "Sonic igniter" all-fire current is spec'd as *4 Amps*. Cold-weather !rocket launch seems to be its own set of interesting problems. -

Interestingly, the modern Estes !rocket "starters" are spec'd as having an all-fire current of *2 Amps*, and my lithium 9V peaks at 1.2A. I'm assuming Estes figures are conservative.... -

@cmhobbs, "smoke alarm battery", by comparison, gave reliable ignition even below 40°F: https://www.ultralifecorporation.com/ecommerce/CatalogItemDetail.aspx?CID=56&IID=628 -

@cmhobbs, IIRC it was ~55°F for the Grav-Mass launch (unusually warm!), and the only successful ignitions were from the batteries that were still warm from having been in my pocket. -

@cmhobbs, alkaline 9V in the launch controller failed to push enough current through the igniter wire to heat it up and ignite the BP motor. -

We did a !rocket launch for !gravmass (to engage all 3 laws), and learned that alkaline #batteries don't cut it below something like 60°F ☹ -

Pretty good !rocket launch w/ @nanohacker, today; chilly outside, but no problems blasting off--hooray for lithium batteries! -

@bobjonkman2, have you been doing your laundry at this #LostSock Laundromat? https://status.hackerposse.com/attachment/9926 -

I think I like it--adaptation's an important part of learning, probably as much collectively as individually: "YOLO Juliet. srsly Hamlet. Macbeth #killingit. Shakespeare goes textspeak" https://status.hackerposse.com/url/9912 !education #shakespeare #freeculture -

@mmn, interestingly, Google removed #JSMin from #Etherpad after acquiring it, not because of what it did but because of the "not for evil" clause in its #license ☺ http://wonko.com/post/etherpad-source-includes-jsmin /cc @kevinmarks -

@kevinmarks Minifying javascript is evil. No wonder Google suggests it! -

@bobbyc, I did make it to the #Nashua Robot Builders meeting on Sunday, though--that was fun: http://nashuarobotbuilders.org/ -

@bobbyc, I didn't make it to the Clojure meetup; mainly poor planning on my part. @palmella also came home and parked me in.... -

Wish working for #SpaceX wouldn't mean having to go west: there's an open position with them that'd actually be a good fit for me, except for being on the wrong side of the country. -

Tempted to apply to #spacex; that could be a good next step after doing #robotany.... #SilentRunning -

@mcscx, the engineering work's done, so #myworkhereisdone; getting more of them out into the world, serving humanity, is up to other people.
