Girls Club, Coalition of Immokalee Workers

CIW had a triumph just before they visited us this month - an agreement with Subway to increase the price paid for tomatoes by 1 cent a pound, thus raising income for workers from $10,000 a year to $17,000. This followed similar deals with MacDonald's, Taco Bell, and Burger King - all of them tough fights.

Look at Day 7 and 8 of their tour blog to see their visit to the Girls Club:

Still not sure I have a handle on the values on the y axis. I'll keep playing. Update: better now. Gnight.

Another update: adding the second graph. But ranges are screwy again.

Vise of our Fathers

DIGIKEY - 366 HEAD & 300 VISE - 396

So my hair is thinning the same way my Dad's did. I'm spending a lot of time tinkering with electronics. I remember how tall his workbench used to seem, the mysterious tools and smells when he worked on his radios. I never knew a lot about what he did at work - he had a security clearance, it was Cold War R&D on the fringes of '50s and '60s Washington D.C. - but I knew it had something to do with the space program. Yesterday I read in Airstream Magazine (I bought a '58 Overlander 2 years ago, to turn into a recording studio in the new Girls Club) that Melpar, my Dad's employer, had built the Airstream-based quarantine units that the astronauts had to stay in when they came back from the moon. Couldn't let alien moon-bugs destroy the Earth.

When he died in '92 he left his workshop as messy as ever. But while he was alive it had an animating intelligence. Afterwards it was mostly junk. But I claimed a circuit-board vise and kept it for the next fifteen or so years. It got lost in the shuffle, though, and I miss it. I'll have to order one just like it. I need it now.

Pachube - First test feeds

history1.png
history2.png



First test graphs. The top two show a snapshot as of this post, using two sliders on an Arduino, as I tested, slept, tested again today including a flatline when I tried a software combination that did not work.

Update: I have reassigned the input sensors, from the sliders (which I was changing myself) to the light and temperature sensors on the shield. I may need to abandon this first feed at some point and start a new one to get a useful range on these new sensors.

At the link below you can see the updated sensor graphs on the Pachube (patchbay) website.

UPDATE: I deleted this feed and created a new one, to use update software on the site. See this post.
