Hackaday Links: August 20, 2017

Posted on by

Foam core, dollar tree foam board, Adams foam board, or whatever we’re calling a thin sheet of foam sandwiched between two pieces of poster board, is an invaluable hacker’s tool. Everyone should have a few sheets on hand, and not just because each sheet is a dollar each at any Dollar Store. [Eric] has been working on a technique to create compound curves in foam board, and the results look great. It’s a true three-dimensional plane with weird curves, and certainly has applications for something.

The Apollo Lunar Module is the first, and only manned space-only spacecraft ever made. The …read more

Hackaday Links: July 23, 2017

Hey, you know what’s happening right now? We’re wrapping up the third round of The Hackaday Prize. This challenge, Wheels, Wings, and Walkers, is dedicated to things that move. If it’s a robot, it qualifies, if it’s a plane, it qualifies, if it passes butter, it qualifies. There’s only a short time for you to get your entry in. Do it now. Superliminal advertising.

Speaking of the Hackaday Prize, this project would be a front-runner if only [Peter] would enter it in the competition. It’s one thing to have a cult; I have a cult and a petition to …read more

Re-Creating the Apollo DSKY’s Display

Posted on by

Apollo astronauts used the DSKY (Display-Keyboard) to interact with the flight computer with a series of 2-digit codes punched into a numeric keypad. Above the keyboard was a high voltage electroluminescent (EL) display whose segments were driven by electromechanical relays; old-ass technology not seen in operation in decades.

[Fran Blanche] is working to re-create the DSKY’s display, and is raising funds to make her first prototype. She was actually able to go dismantle a real DSKY at the Smithsonian, and this drove her desire to re-create the DSKY’s unusual display.

As [Fran] points out in her video, cinematic re-creations typically …read more

Grace Hopper, Margaret Hamilton, Richard Garwin Named for Medal of Freedom

Posted on by

Somewhat hidden among athletes, actors, and musicians, three giants of technology have been aptly named as 2016 Presidential Medal of Freedom recipients. Grace Hopper, Margaret Hamilton, and Richard Garwin all made significant contributions to the technology that envelops our lives and embody the quest for knowledge and life-long self learning that we’d like to see in everyone.

Rear Admiral Grace Hopper’s legacy lies with the origins of computer science. She wrote the first compiler. In a time when computers were seen more as calculating machines than easily adaptable frameworks she looked to the future and made it happen. She continued …read more

Retrotechtacular: Power Driven Articulated Dummy

Posted on by

If any of you have ever made a piece of clothing, you’ll know some of the challenges involved. Ensuring a decent and comfortable fit for the wearer, because few real people conform exactly to commercial sizes. It’s as much a matter of style as it is of practicality, because while ill-fitting clothing might be a sartorial fail, it’s hardly serious.

When the piece of clothing is a space suit though, it is a different matter. You are not so much making a piece of clothing as a habitat, and one that will operate in an environment in which a quick …read more

Apollo: The Alignment Optical Telescope

Posted on by

The Apollo program is a constant reminder that we just don’t need so much to get the job done. Sure it’s easier with today’s tools, but hard work can do it too. [Bill Hammack] elaborates on one such piece of engineering: The Alignment Optical Telescope.

The telescope was used to find the position of the Lunar Module in space so that its guidance computer could do the calculations needed to bring the module home. It does this using techniques that we’ve been using for centuries on land and still use today in space; although now it’s done with computer vision. …read more

Decoding Rediscovered Rope Memory From the Apollo Guidance Computer

Posted on by

On August 25th, 1966, an Apollo Command Module was launched aboard a Saturn IB rocket in mission AS-202. This mission was intended to immediately precede the ill-fated Apollo 1 mission, the AS-202 was unmanned, serving as a test of flight hardware, fuel cells, and the guidance and navigation control systems. This mission used the first Apollo Guidance Computer ever flown, and this mission was vital to testing the computer that would take men to the moon.

While the software from the later missions exists and is available on Github, the earlier Block I spacecraft, including the unmanned Apollo 4 and …read more
