[PCOMP] Lab four and soldering
by Greg on Feb.23, 2011, under ITP, PCOMP
Soldering is so close to soldiering as in soldiering on despite taking on fire and casualties. like my fingers, and my workbench, and quite possibly my lungs! I tried creating my own dc jack and i t hink i am missing something about how to solder. Even drilling in a set of my own helping hands did not make it any easier. It’s like it requires four sets of hands to warm the components, then coordinate the soldering gun and the solder. i had to use the 5 volt output from my arduino to power my board for this lab, which is disappointing, but it was worth it, seeing the multimeter values for voltage and current with switches and LEDs in series parallel.

Science, media, art, movies, politics, and what else I find interesting tweeting and reading on the internet. And ITP.

Composite of a Series of Images Taken From Space Aboard the Space Station
This is a composite of a series of images photographed from a mounted camera on the Earth-orbiting International Space Station, from approximately 240 miles above Earth. Expedition 31 Flight Engineer Don Pettit said of the about photographic techniques used to achieve the images: "My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure." A total of 18 images photographed by the astronaut-monitored stationary camera were combined to create this composite. Image Credit: NASA
