Jeff Hawkins On Early Laptops

Jeff Hawkins, founder of Palm and Handspring on why the first Laptop had trouble in the market: This is an amazing fact. We had this product. It was designed for business executives. And the biggest obstacle, one of the biggest obstacles, we had for selling the product was the fact — believe it or not […]

Getting Heart Rate From Video

From the creatives folks at Fitbit: The basic idea is that the color of your face fluctuates slightly as blood perfusion under the skin changes from your heart’s pumping. If you measure the color change, you can measure heart rate. It sounds simple, but it’s not. One thing that makes this difficult is user motion: […]

Project 1794

Pretty cool records recently declassified. From ExtremeTech: The aircraft, which had the code name Project 1794, was developed by the USAF and Avro Canada in the 1950s. One declassified memo, which seems to be the conclusion of initial research and prototyping, says that Project 1794 is a flying saucer capable of “between Mach 3 and […]

The Genius of Airline Baggage Tag Design

Slate has a great read on the design of airline baggage tags. My favorite part is the description of what the design needs to be able to deal with: Let’s look first at how an ABT is made.

The CD is now 30 years old: The digital music revolution officially hit 30 years ago, on Oct. 1, 1982. While you may be surprised to learn that the heralds of the coming age were, in fact, the Bee Gees, it probably comes as less of a shock to learn that Sony was at the […]

It’s a really clever idea with some pretty awesome engineering behind it. I’m skeptical it will catch on however. While it looks great in […]

Automated Construction

Invisible Airbag Bicycle Helmet

This helmet looks pretty discrete when you put it on. Like an odd turtleneck or scarf. However it’s using accelerometers so that when triggered it inflates like an airbag in a fraction of a second. The result is this: It potentially will solve the problem of people not liking helmets when bike riding. However it […]

Air France Flight 447

Air France Flight 447 is the most puzzling crash since TWA Flight 800 because it just doesn’t make sense for the pilot to pull back and increase the angle of attack if they believed they were in a stall situation. The NY Times reports: The report offered an answer to a central puzzle: the consistent […]

More On Cell Phones vs. Toilets

India has 919 million [pdf] mobile phone users as of March 2012. That’s out of a 1.2 billion (per Wikipedia) population. That’s about 75% of the population. Less than 50% of homes have toilets in India. It’s even worse for women in India to the point of a Right to Pee campaign. I’ve touched on […]
