Visit the Exploratorium After Dark tonight!

Exploratorium After Dark - $14, Tonight 6-10PM

Tonight from 6-10PM, The Exploratorium keeps their doors open late for Exploratorium After Dark, an adult-oriented evening at my favorite science museum. EAD takes place on the first Thursday of every month.

I went last month and enjoyed being able to spend time at my favorite exhibits without being pushed aside by hoards of small children on their school field trips.

More information about tonight’s event is below. Every month has special guests, and in addition to the special features you are free to hang out at the cash bar or roam the museum.

Admission is $14.  Members get in free!

Fire and Ice

Thursday, December 3, 2009
6:00-10:00 p.m.
Bar opens at 6:00 p.m.

When the temperature outside starts dropping, the Exploratorium will be heating up and chilling out with “Fire and Ice,” its December After Dark event, featuring fire sculptures, ice sculptures, and more!

Enjoy cocktails on ice, sizzling tunes, and stunning displays and explorations of fire, ice, heat, and cold. The evening will feature works of fire art, including the Pyrograph, by Earl Stirling. Like a fiery version of the Exploratorium’s classic Drawing Board exhibit, Pyrograph lets you swing a pendulum across a sandy, flaming cauldron and trace out oscillating patterns in fire. Burning sculptures, flaming experiments, and other sizzling delights will round out the high-temperature portion of the evening.

At the opposite end of the thermometer, award-winning ice sculptor David Fong will rev up his chainsaw and carve a 300-pound block of ice into a frosty work of art before your eyes. Stop by our insulation demonstration to learn how to ward off the chill of winter. And we’ll find out once and for all which materials makes the best barriers against the cold: Blubber? Down? Or perhaps a less likely candidate-steel wool.

Hovering between these extremes will be Fog Pool, an artwork by Charles Sowers, with swirling, turbulent clouds that you can touch. Fire and Ice will also offer special exhibit demonstrations and floorwalks that delve into temperature extremes: Feel how bringing different temperatures together can confuse your fingers at Hot and Cold Coils, and learn how your hands adapt to temperature at Hot and Cold Chimneys. Plus, see ice in action at Watch Water Freeze.

LTspice Class Slides and Keyboard Shortcuts

LTspice 2009 World Tour

Yesterday I drove down to Linear Technology in Milpitas for a free LTspice IV Seminar, hosted by electronics distributor Nu Horizons.

The seminar was led by LTspice author and advocate Mike Engelhardt.  For someone like me who has never used LTspice before but wanted to see what all the fuss was about, the seminar was an extremely informative introduction to what appears to be a very powerful and well-supported design tool based on Berkeley SPICE.  Mike claims that in most cases, LTspice is the fastest SPICE simulator around, making it the industry leader both in price (it’s free) and performance.

The best part?

After the seminar, Michael Payne of Nu Horizons sent out a link to the class slides and example files as well as a list of useful LTSpice Keyboard Shortcuts.  So even if you missed the class (or the tour didn’t include your part of the world), you can still learn about the circuit simulation tool that has been making waves in the open source hardware community.

HSC 45th Anniversary Sale

HSC is having some online specials too, although if you shop online you are missing out on 90% of the fun, such as sifting through crates of miscellaneous electronics parts!

HSC Warehouse Clearance Sale

Every project I work on usually involves at least one trip down to the South Bay to visit HSC, and I usually find at least a few interesting odds and ends at their annual clearance sales.  And while you’re in the area, I highly recommend a side trip to Weird Stuff Warehouse in Sunnyvale as well.
