Little Padded Envelopes from China
Hardly a week goes by without some little padded envelopes in my mailbox. 16×2 LCD character displays, 74HCT541 IC’s, 6mm encoders, some 10mm spirit levels, a couple more ESP-01 modules, and that is just this last month. Living on an island in the middle of the Pacific, there is no place I can buy electronic components. I must order everything.
The surreal part of this is that it is even conceivable that it would be cost effective to buy components from halfway around the globe like this. Not only is it affordable, but it is easy. It is easy to locate the correct components , it is easy to pay for the items, and it is easy to ship the parts across oceans.
Just a few years ago, buying products like this would have indeed been an insurmountable challenge, now it is routine. The internet and electronic storefronts like eBay that make shopping easy.
Electronic payment networks, notably PayPal, that make payment easy. And a global shipping network capable of getting those little padded envelopes to the correct location. For anyone familiar with history these networks are simply stunning in their capability, something inconceivable even a few decades ago.
Some would question the quality of components from China. You do need to be careful, but unlike cheap consumer goods, electronics components are usually quite acceptable in quality. I have had very little trouble ordering from Asia, the items perform as advertised.
I would probably not order from China if building life support equipment. For my little electronics projects the stuff works. Just check the seller’s ratings and record, then press ‘Buy it Now’.
Early Morning on the Mauna
Sometimes it is worth heading up the mauna for the early shift…
The Moon and Venus
Tomorrow morning, May 22nd, a pretty crescent Moon will be located close to a brilliant Venus. The Moon will be a slim 15% crescent a little over 3° from Venus shining at -4.4 magnitude. The pair will rise about two hours before sunrise at about 3am, look for the two above the brightening glow of dawn.
Mercury at Maximum Elongation
Today Mercury will be at maximum western elongation, as high in the morning sky as it will appear for this current apparition. After today the planet will slide back into the dawn, passing through superior conjunction on June 21st to reappear in the evening in mid-July.
There are no transits of Mercury in 2017, the next will be Nov 11, 2019.
First Fish
Among the tribes of the coastal northwest there is a ceremony that surrounds the first fish of the season. These ceremonies might vary from tribe to tribe, from family to family, but every tribe had such a ceremony.
Life once depended on the yearly return of salmon to the rivers and streams each summer. For bears, eagles, and humans the annual bounty of salmon provided the nourishment that would see them through the long winter. The forest itself benefits from the nutrients carried from distant seas into the trees where the salmon would spawn and die.
Upon catching the first salmon of the season the tribe will stop and celebrate. They celebrate the life of the fish, they celebrate the cycles of the natural world, they celebrate their connection with nature. Some protocols insist that the first fish be released, to continue upriver to spawn, to ensure the salmon continue to return each summer.
That one idea is the critical bit, our connection with nature. Any fisherman understands that he takes from the natural world. A good fisherman stops and considers what he takes. He takes only what he needs to feed his family. This is the entire point of the first fish ceremony, it serves to educate the community in the act of taking, to limit what you take to what the environment can provide.
I grew up in a hunting and fishing family, where a considerable portion of our food came from what my father caught or shot. Be it elk, deer, ducks, razor clams, or smelt, so many of my childhood memories center around the capture, preparation and storage of food… Chopping, packaging and freezing an elk was a serious amount of labor for the entire family.

Fun at AstroDay
In the ten years I have lived on island I have never missed an AstroDay. This year was no change to that streak, I volunteered to do the last shift on the Keck Observatory table, 2-4pm. Show up at lunchtime, enjoy the activities myself for a while, say hi to everyone I know there, then do my shift on the table… Good plan.
I was pleasantly surprised with this little thermal camera, it does a nice job costing only a few hundred dollars. Using the iPad linked to a large display using AirPlay the setup worked quite well in practice. I could handle the camera with no wires to tether me to one place.
