There is one kind of robber whom the law does not strike at, and who steals what is most precious to men: time. ~Napoleon I
1898 – M. C. Escher, Dutch illustrator is born.
Maurits Cornelis Escher, usually referred to as M. C. Escher, was a Dutch graphic artist. He is known for his often mathematically inspired woodcuts, lithographs, and mezzotints. These feature impossible constructions, explorations of infinity, architecture, and tessellations.
1985 – STS-51-G Space Shuttle Discovery launches carrying Sultan bin Salman bin Abdulaziz Al Saud, the first Arab and first Muslim in space, as a Payload Specialist.
STS-51-G was the eighteenth flight of NASA’s Space Shuttle program, and the fifth flight of Space Shuttle Discovery. The seven-day mission launched from Kennedy Space Center, Florida, on June 17, 1985, and landed at Edwards Air Force Base, California, on June 24. Sultan Salman Al Saud of Saudi Arabia was on board as a payload specialist; Al Saud became the first Arab, the first Muslim, and the first member of a royal family to fly into space. It was also the first Space Shuttle mission which flew without at least one astronaut from the pre-Shuttle era among its crew.
2011 – Adafruit adds Waterproof DS18B20 Digital temperature sensor + extras to the store
This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don’t get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. Read more.
2013 – New Adafruit tutorial in the Learning System: Blinking an LED with BeagleBone Black
In this tutorial, you will learn how to control an external LED using a BeagleBone Black (BBB) from Python. Because the BBB runs Linux, there are many ways in which it can be programmed. In this tutorial we show how to control an output pin and hence LED using Python. Read more.
