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


Road? Where we’re going, we don’t need roads. – Dr. Emmett Brown. For the third edition of Time Travel Tuesday, we’ll be looking at Christmas day here at Adafruit, across the DIY, open source and science/tech world!

We tried to turn off a lot of TVs.

On MAKE “HOW TO – HDR photography in Gimp or Photoshop”.



Ladyada publishes the wavebubble:

I jammed Santa’s GPS so he couldn’t find his way to your house – “In a high-population-density city, inhabitants must be prepared to defend their own personal space. Technologies that increase personal productivity are on the rise, even though they may intrude on others. The unavoidable reaction is to create technologies that counteract other people’s devices. Wave Bubble is a product that counters the all-too-familiar annoyance of loud ring tones and overt cell-phone conversations in public.“

Also covered on Hack-a-day & MAKE.

Ernst Ruska Electron Microscope - Deutsches Museum - Munich-Edit

Ernst August Friedrich Ruska (Born 25 Dec 1906) was a German electrical engineer who invented the electron microscope (more @wikipedia).



Sir Isaac Newton (Born 25 Dec 1642). English physicist and mathematician, who made seminal discoveries in several areas of science, and was the leading scientist of his era. His study of optics included using a prism to show white light could be split into a spectrum of colours.

This day in history from the History channel (video). Worth noting, Dec 28, 1895 First commercial movie screened.

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.
