Weekend Ed. Quote~November 22

We build these bridges of insight through empathy, the effort to see the world through the eyes of others, understand the world through their experiences, and , and feel the world through their emotions. ~Tim Brown

Design Journal 12: A Twilight Visit to Radio Shack

The Oldest Padawan on Tython ventured to Radio Shack (on this planet) last night at sunset.

Radio Shack at Twilight on Planet Earth

I was the only female in the place.

I had been working in the Maker Lab, disassembling my American Airlines-issued headphones when I discovered that the wires were too thin to solder. (Aside: I was so happy to have a “Too thin” issue ascribed to me!). I bought my 1/8 Stereo plug…and…then…looking around….I saw these super cute dancing LED Speakers (click on the picture):

And, right next door to Radio Shack was the cutest Beauty Supply store!! So I bought these super cute bows!

Lovin’ Radio Shack at Twilight!!!

Design Journal 11: A Stitch in Time and Time to Stitch

The way to get started is to quit talking and begin doing. ~Walt Disney

Time for Stitching:

StitchingI 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.

What is the Opposite of Choice?

choice antonyms



“In general, All technologies gives us more choices…but all technologies also have the burden of choice, they force more choice.” ~Douglas Rushkoff (57:43)

“The easiest way to de-bug reality is to stop when it is not working.” ~Douglas Rushkoff

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?

Design Journal 10: Keep Calm and Ohm On

NOTE: This post contains Science curricular tie-ins…read at your own learning acquisition risk!


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.

Resistor Bands

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.

Design Journal 9: Revised Schematic

You cannot create experience. You must undergo it. ~Albert Camus

My original schematic for me Voice Playback Integrated Wearable has undergone a change. I found that I needed a Transformer to connect the 5V Voice Recorder to the 3.3V Lilypad. The Transformer will connect the Voice Recorder to the Lilypad. I am learning a lot from the “Bald Wisdom” website, in particular the post “Electrify Your Halloween Making Things Scream.”

New Schematic



I am also searching to add to the code I have copied from SparkFun, to find something called “RP” to help synchronize the sound and blinkey lights. I will need to have automatic sound delivery followed by the blinkey lights. I am undecided right now as to whether the blinkey lights will signal all at once or in a progression.

Design Journal 8: Yes and No in the Maker Lab

A ‘No’ uttered from the deepest conviction is better than a ‘Yes’ merely uttered to please, or worse, to avoid trouble ~Mahatma Gandhi



Opening the orange boxes from SparkFun and reading carefully (with my glasses on!) I notice that there are different numbers on the Sound Recorder and the Lilypad. The Sound Recorder runs on 5V and the Lilypad which uses 3.3V. The difference between 5V and 3.3V matters. The Transformer part will connect the two components.

I appreciate the MKOs in the Maker Lab for telling me about this distinction. They delivered the gentle “no” on not purchasing a Transformer very casually and matter-of-factly. We move quickly from “need to” to “how to do it.” We have several parallel conversations on the merits of different shipping options and shipping carriers. I really don’t have time to wait on shipping. One person is going to a bigger city and could source the Transformer, one says to “bite the bullet” and pay the $24.00 shipping charges. We digress to discuss the Transformers movie franchise but eventually I click “Enter” and order the tiny part with the hefty shipping:
