Crypto-Eye: Analyze the Crypto Currency Market with Color Sensors
https://blog.adafruit.com/2018/07/16/crypto-eye-analyze-the-crypto-currency-market-with-color-sensors/

This project was sent in by John and shared on Instructables by XenonJohn:

Uses an Adafruit TCS34725 red/green/blue colour sensor to analyse the light output from the on-screen order book when crypto trading.

If predominantly “buy” orders come in, represented by green numbers on screen, you might possibly expect the value of your favourite coin to increase in the ultra-short term. If predominantly red “sell” orders start to fill the order book, then you might possibly expect the value of your coin to fall in the ultra-short term.

Therefore, here comes the innovative step, what would happen if you were to analyse the light output of just that section of your computer screen that is showing the order book, and then work out changes in the ratio of green light to red light over time?

This project uses an Adafruit TCS34725 red / green / blue light sensor attached to an Arduino Nano, fitted into a foil lined cardboard enclosure in turn mounted over the order book part of your cryptocurrency trading platform on screen view. It determines the mean red to green ratio over time and then alerts you with verbal warnings if the instantaneous red to green ratio measurement is moving away from this mean central area towards the red or green.

Any trading decisions you make based on this are entirely up to you! I have no idea if this is of value or not for trading but felt compelled to try it to see if it works as an idea. It does.

Biohacking : Optimizing the Warm Up
https://blog.adafruit.com/2018/07/16/biohacking-optimizing-the-warm-up/

A proper warm up before going for a run sounds like a good idea. How long should the warm up be and at what effort level? We want to warm up our muscles and increase our range of motion without compromising our performance. Many studies have looked into different aspects of the warm up and recorded various physiological responses, but few studies have focused on achieving optimal performance. We will take a closer look at two studies that came to roughly the same conclusion about the structure of an optimal warm up for peak performance.

Both studies found the sweet spot for a warm up was ~15 minutes at 60% effort would lead to optimal performance. Deviating from this and warming up significantly by moving at a slower pace showed no advantages. Attempting to warm up at faster at more than a 70% effort caused a 9-16% drop performance. The 1998 study “The effect of warm-up intensity on range of motion and anaerobic performance” found a 6% boost in aerobic performance and a 7% increase in anaerobic performance.

The unfortunate participants in these studies were on a treadmill with a rectal thermocouple in place to measure their core temperature. Skin temperature was also monitored. The muscles were found to rapidly increase to temperature during warm up within 5-10 minute they were at their ideal operating temperature. The core body temperature was slower to rise taking over 30 minutes. Several studies have looked into tested stetching and passive forms of warming up (hot baths, saunas and heating pads). The most effective form of warm up seems to be a lower effort version for the activity your are about to embark on. Runners would start with a fast walk and move into a jog over 15 minutes.

Reinstalling a Transcendent TV Artwork #ArtTuesday
https://blog.adafruit.com/2018/07/17/reinstalling-a-transcendent-tv-artwork-arttuesday/

via HYPERALLERGIC

Anxiety abounds when you are about to install a work by Nam June Paik. The master of media art created works that are as ephemeral as they are transcendent, constructed out of TV sets and recording devices that are no longer manufactured and, needless to say, generally irreplaceable.

So when Charlie Wylie, Santa Barbara Museum of Art’s Curator of Photography and New Media, decided to re-install Paik’s T.V. Clock after nearly 10 years of being off view at the museum, he just kept thinking: “I have 24 backups.”

Lucky for Wylie, all 24 original TV sets functioned as designed, with television technician guru, Darryl Widman, having to only mildly re-align the wiring as the artist intended.

T.V. Clock is created out of Samsung TV sets from the 1980s and mounted upright on black pedestals, placed in a gentle arc across the exhibition space. Rather than have the TVs play from a videotape or disk, Paik manipulated their wiring so that a straight white line appears on each screen. Viewed together, the lines simulate the hands of a clock, each screen representing an hour of time, statically rotating its way across the installation.

For Paik, the television was an aesthetic tool through which to consider questions about time and reproducibility and how telecommunications shape our understanding of history and culture. Throughout his work, he considered what the TV was and what it could become, tackling both the technical and conceptual question of how information travels through clever manipulations of electronic media.

Put the Adafruit HUZZAH Feather ESP8266 to Deep Sleep with One Wire and One Line of Code
https://blog.adafruit.com/2018/07/17/put-the-adafruit-huzzah-feather-esp8266-to-deep-sleep-with-one-wire-and-one-line-of-code/

Very cool project spotted over at arduinotronics:

My Adafruit HUZZAH Feather ESP8266 consumes 0.080 amps (80 ma) in normal operation. With one wire and a single line of code, I can drop that to about 0.010 amps (10 ma), according to my USB power monitor.

Artistic World With Humans But Without Human Presence
https://blog.adafruit.com/2018/07/17/artistic-world-with-humans-but-without-human-presence/

Creative Boom features the interesting Richard Keeling project using colour to distract the viewer from the absence of humans:

Illustrator Richard Keeling (featured previously) has just returned from a trip around the world and wanted to get his head back in the game with a fresh series entitled Presence. Focusing on his usual bright colour palette and abstract approach, the collection of illustrations feature absolutely no humans but there’s a hint that they’re there, just lurking out of shot, hidden away from us.

Maison Margiela’s Artisanal couture collection is designed for “neo-digital natives”
https://blog.adafruit.com/2018/07/17/maison-margielas-artisanal-couture-collection-is-designed-for-neo-digital-natives/

Via DeZeen

John Galliano’s Artisanal AW 2018 women’s collection for Maison Margiela features layers of sorbet-coloured garments worn back to front and iPhones clamped to model’s calves.

Galliano, who has been creative director of avant-garde label Maison Margiela since October 2014, designed the collection for a “new tribe [of] neo-digital natives”.

Next-Gen EEG Could Help Bring Back Lost Brain Function
https://blog.adafruit.com/2018/07/17/next-gen-eeg-could-help-bring-back-lost-brain-function/

via Stanford University

Our brain is an intricate network of hundreds of billions of neurons, and anything that interrupts this network, such as abnormal brain development or a stroke, can cause severe disorders, including epilepsy, depression, anxiety, visual impairment, chronic pain and paralysis.

Stimulating brain tissue alters the way neurons fire and helps the brain form neural connections. Norcia’s research focuses on applying the method to cases of visual impairment, such as amblyopia (lazy eye) and strabismus (crossed eyes), and on better understanding phenomena like binocular rivalry, which describes the fact that when presented with two different images at the same time, we can only be aware of one at a time.
