Time travel Tuesday #timetravel a look back at the Adafruit, maker, science, technology and engineering world
“It is only possible to live happily ever after on a day-to-day basis.” ~Margaret Bonanno
1927 – The Ginza Line, the first subway line in Asia, opens in Tokyo, Japan.
The Ginza Line was conceived by a businessman named Noritsugu Hayakawa, who visited London in 1914, saw the London Underground and concluded that Tokyo needed its own underground railway. He founded the Tokyo Underground Railway in 1920, and began construction in 1925.
The portion between Ueno and Asakusa was completed on December 30, 1927 and publicized as “the first underground railway in the Orient.” Upon its opening, the line was so popular that passengers often had to wait more than two hours to ride a train for a five-minute trip.
1950 – Bjarne Stroustrup, Danish computer scientist, created the C++ programming language is born.
Bjarne Stroustrup is a Danish computer scientist, most notable for the creation and development of the widely used C++ programming language. He is a Distinguished Research Professor and holds the College of Engineering Chair in Computer Science at Texas A&M University, a visiting professor at Columbia University, and works at Morgan Stanley.
The Samoa Time Zone observes standard time by subtracting eleven hours from Coordinated Universal Time (UTC-11). The clock time in this zone is based on the mean solar time of the 165th meridian west of the Greenwich Observatory.
The zone includes the U.S. territory of American Samoa, as well as the Midway Islands and the uninhabited islands of Jarvis, Palmyra, and Kingman Reef.
The zone is one hour behind Hawaii-Aleutian Time Zone, one hour ahead of Howland and Baker islands, and 23 hours behind Wake Island Time Zone.
The nation of Samoa also observed the same time as the Samoa Time Zone until it moved across the International Date Line at the end of 29 December 2011; it is now 24 hours (25 hours in summer) ahead of American Samoa.
Sales of the open source BeagleBone Black SBC, which began shipping in May, have surpassed 100,000 units according to BeagleBoard.org.
BeagleBoard.org launched the first major community-backed open source single board computer (SBC) when it shipped theBeagleBoard back in 2008. Since then, the TI-oriented community group has spun off several BeagleBoard versions, and followed up with a smaller, cheaper BeagleBone board in 2011. A faster, cheaper, and HDMI-ready BeagleBone Black model appeared in May of this year.
The 100,000 unit figure is on the conservative side, according to Dave Anders, Senior Embedded Engineer at Circuitco, as it reflects only what has been sold directly to distributors such as Digikey, Mouser, and Adafruit.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
