It will take a train car of popcorn to get through all these. I'm starting with the Fantastic Inventions playlist featuring Brilliant Invention to Boost Men's Confidence
 
Oh. If you are a history buff...

I did a spot check and the answer is yes, but I'm not sure the captions are official from Pathe.

For the rural poor, of course. But my wife is a health assistant at a major metropolitan school district that can't afford more than the simplest vision screening. (I'm too embarrassed to mention the school district by name.) Selling these in the US public health market might seed the funding for further expansion.
 
Smartphones bring eye exams to rural poor.

Long story short, a pacemaker failure caused a real blue screen of death, followed by a reboot.

I, for one, welcome our entertaining robotic overlords.

Yeah, I know I'm promoting slacker clicktavism but it couldn't hurt and you can always write your Congers Critter directly.

Several companies, notably Intel and Apple, are going the conflict-free route but Fairphone led the way. Lot's of good detail in the article. #fairphone  
 
If you’ve been following our story on Precious Materials, specifically mining in DR Congo, then you know for Fairphone, the use of conflict-free minerals in the production of consumer electronics is an important issue and part of our mission toward fairer electronics.

Quite a lot of discussion about conflict minerals stems from an American law, commonly called the Dodd-Frank Act, signed into federal law in July 2010. Within the Act, Section 1502 deals specifically with the use of conflict minerals. This year the concrete implications of this legislation are being felt as the deadline to comply with the new standards comes in May. While the law only applies to companies listed on the US stock exchange, its effects will be felt by the industry as a whole as most American companies have a reach beyond the American consumer market and throughout the world.

This blog gives you an update on the status of the Dodd-Frank Act in the US, related developments in Europe, and how the industry and Fairphone are involved.

US requires disclosure of conflict minerals by end of May
EU legislation builds upon lessons learned in the US

We understand the EU proposal, specifically its voluntary participation, is not perfect, but it’s a good start: If this framework is in place and tested, a next step can be taken to make due diligence compulsory for companies downstream.

In our opinion, and after gaining a better understanding of the perception and apprehension of many companies, this approach will have a better chance (than the American law enforced approach...) at creating positive impact than a mandatory law. That being said, we do believe that in the end, critically examining one’s supply chains and evaluating impact should be an industry-wide practice, which could need legislation if the industry does not engage voluntarily. For now, this is a great first step that should inspire disclosure and engagement throughout the industry.

A point of criticism at this early stage would be that the proposal is currently limited to only tantalum, tin, tungsten and gold. There many more minerals with social and environmental consequences which need to be addressed (for example, platinum, cobalt, and copper). However, we remain hopeful and recognize that just like Fairphone’s own approach, the EU can only make improvements one step at a time.

Liked most a lot, except for the overpopulation of the military family and husband notion that the wife ”steps in" when he is gone. She stands in the gap every day, I'm sure.

Very cool. Could you tune the chamber to a resonant frequency that would generate a visible train of vortex rings?

Maybe PVC of different diameters and lengths with some reducing fittings? Let the theory get you close and finish the tuning with a hacksaw?

I backed Mowayduino on indiegogo a while back. My robot arrived a couple weeks ago and I've been playing with it through the Arduino IDE. It's just a ton of fun. Nice design, good solid build.

I haven't dug into sensing yet but can control the lights and motors. When I put it through it's paces on the mat, there was some wheel slip but other than that, it's a really nice little learning tool.

The folks at http://moway-robot.com/en/ have done a great job.

I don't have many heroes but I just added one to my list.
 
Arvind Gupta is the creator of the “Toys from Trash” YouTube video series, which teaches engineering principles to kids by showing how to make simple toys from common materials.

"My personal satisfaction comes from seeing the happiness and gleam in the eyes of kids around me who learn new things from my toys. Schools try to cram similar material into students, but when kids do it for themselves — learn basic physical principles that way — their eyes glitter, and that’s my happiness."
