The Philae probe from the European Space Agency’s Rosetta Mission, launched in 2004, sped through 6.4 billion miles of space and landed on a comet 310 million miles from Earth today! According to CNN, “The lander weighs about 220 pounds and is the size of a domestic washing machine. The target comet is only 4 kilometers, or 2.5 miles, in diameter.”

Comet Landing-a project 10 years in execution

Time for Stitching:
I am stitching with gray, connective thread from the various components (LED lights, on/off switch, voice recorder) back to the Ground component on my Voice Playback Integrated Wearable. Each line is distinct and must be sewn separately. The positive loop of the component must always connect back to the Ground. The stitches do not have to be close together as I learned in 4th grade Home Ec class, but the connective thread lines can’t criss-cross or intersect.

Google Art Project
“The Art Project is a collaboration between Google and 151 acclaimed art partners from across 40 countries. Using a combination of various Google technologies and expert information
provided by our museum partners, we have created a unique online art experience. Users can explore a wide range of artworks at brushstroke level detail, take a virtual tour of a museum
and even build their own collections to share.”

Where are the choices that don’t fit?
What is the opposite of choice?
Is there a concept of the opposite of choice? Is it tyranny? despotism?

This is the symbol for Ohm.
Ohm references unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt. It is named after German Georg Simon Ohm who even has his own Law (Note: there is not a without-the-e typo in Georg–dude must have been too busy inventing ohms to add the last “e.”)
Ohms are units of measure on Resistors.
I learned in the Maker Lab that my Voice Playback Integrated Wearable needs the 56KOhm Resistor* so it can tell my Voice Recorder how many times per second to pull the microphone. The times per second is also known as the “sampling rate” which is the number of times a signal is measured (sampled) per second. The unit of sample rate is “samples per second.” This is often expressed in kiloHertz (kHz). For example, “CD quality” sound has a sample rate of 44 kHz. Source
I am making a digital recording, versus an analog recording because the code I am using will save the recording as a series of 1’s and 0’s.

*thanks to Kim, in C19, for traveling to Micro Center in Tustin to pick up my 56K Ohm Resistors (price $1.95).
