Time travel Tuesday #timetravel a look back at the Adafruit, maker, science, technology and engineering world

Road? Where we’re going, we don’t need roads. – Dr. Emmett Brown. Here’s a look back at the maker world and beyond!


Pt 10745
On ASK AN ENGINEER we released our touchscreens. On MAKE Phil invited Marissa Mayer to Maker Faire. Hack-a-day had a Security Audit Kit in a Mouse.


Pt 2500
Alicia Gibb’s “New Media Art, Design, and the Arduino Microcontroller: A Malleable Tool”… on MAKE “Maker Birthdays: Douglas Engelbart”, on Hack-a-day reviewed the iPad.


On MAKE, Building papercrete domes. UHF power harvesting on Hack-a-day.


On MAKE, DIY ApplesauceGrid enabled USB Microscope on Hack-a-day.


On MAKE, Call for Makers: Maker Faire Bay Area 2007. Cakebot: mindstorm cake slicer on Hack-a-day.


Burning visible images onto CD-Rs with data (beta) – MAKE. Hack-a-day, Robotic motion sensing using an optical mouse.

Way Back In Time…

On January 30, 1950, the development of the hydrogen fusion bomb was ordered by President Harry Truman. This new type of thermonuclear device was far more powerful than the fission bombs used against Japan in WWII.


On February 1st, 101 years ago, fingerprints were used for the first time in the US to convict a person in a court of law. Thomas Jennings was sentenced to death and hanged in Cook County, Illinois for the murder of Clarence Hiller.

Crystallographer Kathleen Lonsdale was born 110 years ago yesterday.  She developed new x-ray technology in order to study crystal structures. Her work, though seemingly esoteric, had an enormous impact on organic chemistry. She was the first woman to be elected (1945) to the Royal Society of London.  Born into an Irish middle class family of ten at a time when it was rare for women to even attend college, she went on to become a tenured professor at University College London and the first woman president of the Union of Crystallography.


The first commercially viable “mechanical calculating machine” was patented to a William Seward Burroughs, born January 28, 1855. The patent was submitted in 1885 and he formed his company, the American Arithmometer Company, shortly after, in 1886 (we kind of wish there were still companies around with names like that…) The wealth built by his invention enabled his grandson, William S. Burroughs II, to become a member of the beat generation instead of a banker. You could say his poetry was built partly by a calculator…

(Not specific to January, but sort of feels that way after last week…)
In 1400, and a few centuries before and after, it was significantly colder across the globe than normally… the world was in the midst of the Little Ice Age. Average temperatures across the globe plunged and stunted human population growth and agricultural potential for much of the (normally) temperate world.  The Norse colonies in Greenland starved and vanished and the population of Iceland was halved.  Certain agricultural products were abandoned because of changing rain patterns…orange crops in southern China failed and the Thames River in London froze.  The Little Ice Age only ended about one hundred years ago, at the end of the 19th century or the early 20th century, bringing about another re-adjustment in agriculture and population (ahem, Great Plains).

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. Development of a thermonuclear (hydrogen) bomb began during the the Manhattan project and a great deal of work had been done *before* Truman’s directive in 1950. It was in no small part this work done at Los Alamos that prompted the directive in the first place:
