The OpenMv Cam aims at becoming a super powerful Arduino with a camera […]

Glowing mercury thyratrons: Inside a 1940s Teletype switching power supply

Ken Shirriff take a look inside a bulky DC power supply REC-30 rectifier, how it works and contrast it with a MacBook power supply:

We recently started restoring a Teletype Model 19, a Navy communication system introduced in the 1940s.14 This Teletype was powered by a bulky DC power supply called the “REC-30 rectifier”. The power supply uses special mercury-vapor thyratron tubes, which give off an eerie blue glow in operation, as you can see below.
The power supply is interesting, since it is an early switching power supply. (I realize it’s controversial to call this a switching power supply, but I don’t see a good reason to exclude it.) While switching power supplies are ubiquitous now (due to cheap high-voltage transistors), they were unusual in the 1940s. The REC-30 is very large—over 100 pounds—compared to about 10 ounces for a MacBook power supply, demonstrating the amazing improvements in power supplies since the 1940s. In this blog post, I take a look inside the power supply, discuss how it works, and contrast it with a MacBook power supply.

Science Fair shows brainy teenagers in National Geographic documentary #MakerEducation

via Adafruit:

The Washington Post reviews the new documentary Science Fair.

What happens when you put 1,700 of the world’s smartest teens together and ask them to show their scientific stuff?

You may get more than you bargained for.

“Science Fair,” a new documentary, follows teenagers through the highs and lows of the Intel International Science and Engineering Fair, the world’s largest pre-college science competition.

The fair, at which young people compete for millions of dollars in prizes, is a hotbed of scientific research. It’s also a hothouse of competition and teenage angst, as the documentary shows.

The film follows nine teenagers seeking to change their lives through science. Among them: Kashfia, a young Muslim who feels out of place in her large South Dakota high school and dreams of escaping small-town life through science. Robbie, a West Virginia math whiz with terrible grades, who wants to meet other kids who share his niche interests. And Anjali from Louisville, who contends with helicopter parents as she navigates the weird world of competitive science.
