Ask Hackaday: What Are Your Apollo Memories?

July 10, 2019 by Dan Maloney 62 Comments

This month will mark the 50th anniversary of the Apollo 11 mission that brought to a successful conclusion the challenge laid down by President Kennedy only eight years earlier. Three men went to the Moon, two walked on it, and they all came back safely, in a dramatic eight-day display of engineering and scientific prowess that was televised live to the world.

If you’ve made more than 50 trips around the sun, chances are good that you have some kind of memories of the first Moon landing. An anniversary like this is a good time to take stock of those memories, especially for something like Apollo, which very likely struck a chord in many of those that witnessed it and launched them on careers in science and engineering. We suspect that a fair number of Hackaday readers are in that group, and so we want to ask you: What are your memories of Apollo?

A Real American Hero

My memory of the Moon landing is admittedly vague. I had just turned five the month before, hadn’t even started kindergarten yet, but I had already caught the space bug in a big way. I lived and breathed the space program, and I knew everything about the Mercury missions that were over by the time I was born, and the Gemini missions that had just wrapped up. Apollo was incredibly exciting to me, and I was pumped to witness the landing in the way that only a five-year-old can be.

It’s NICER In Orbit

July 9, 2019 by Dan Maloney 1 Comment

Given the sheer volume of science going on as the International Space Station circles above our heads every 90 minutes or so, it would be hard for any one experiment to stand out. ISS expeditions conduct experiments on everything from space medicine to astrophysics and beyond, and the instruments needed to do the science have been slowly accreting over the years. There’s so much stuff up there that almost everywhere you turn there’s a box or pallet stuck down with hook-and-loop fasteners or bolted to some bulkhead, each one of them doing something interesting.

The science on the ISS isn’t contained completely within the hull, of course. The outside of the station fairly bristles with science, with packages nestled in among the solar panels and other infrastructure needed to run the spacecraft. Peering off into space and swiveling around to track targets is an instrument with the friendly name NICER, for “Neutron Star Interior Composition Explorer.” What it does and how it does it is interesting stuff, and what it’s learning about the mysteries of neutron stars could end up having practical uses as humanity pushes out into the solar system and beyond.

Teardown: VeriFone MX 925CTLS Payment Terminal

July 8, 2019 by Tom Nardi 53 Comments

Regular Hackaday readers may recall that a little less than a year ago, I had the opportunity to explore a shuttered Toys “R” Us before the new owners gutted the building. Despite playing host to the customary fixture liquidation sale that takes place during the last death throes of such an establishment, this particular location was notable because of how much stuff was left behind. It was now the responsibility of the new owners to deal with all the detritus of a failed retail giant, from the security camera DVRs and point of sale systems to the boxes of employee medical records tucked away in a back office.

Clipping from New York Post. September 24th, 2018.

The resulting article and accompanying YouTube video were quite popular, and the revelation that employee information including copies of social security cards and driver’s licenses were left behind even secured Hackaday and yours truly a mention in the New York Post. As a result of the media attention, it was revealed that the management teams of several other stores were similarly derelict in their duty to properly dispose of Toys “R” Us equipment and documents.

Ironically, I too have been somewhat derelict in my duty to the good readers of Hackaday. I liberated several carloads worth of equipment from Geoffrey’s fallen castle with every intention of doing a series of teardowns on them, but it’s been nine months and I’ve got nothing to show for it. You could have a baby in that amount of time. Which, incidentally, I did. Perhaps that accounts for the reshuffling of priorities, but I don’t want to make excuses. You deserve better than that.

So without further ado, I present the first piece of hardware from my Toys “R” Us expedition: the VeriFone MX 925CTLS. This is a fairly modern payment terminal with all the bells and whistles you’d expect, such as support for NFC and EMV chip cards. There’s a good chance that you’ve seen one of these, or at least something very similar, while checking out at a retail chain. So if you’ve ever wondered what’s inside that machine that was swallowing up your debit card, let’s find out.

Manufacturing In China Hack Chat

July 8, 2019 by Dan Maloney 5 Comments

Join us on Wednesday 10 July 2019 at noon Pacific for the Manufacturing in China Hack Chat with Jesse Vincent!

It started out where many great stories start: as a procrastination project. Open source developer Jesse Vincent decided that messing around with a new keyboard design was a better thing to spend time on than whatever he was supposed to be doing, and thus Keyboardio was born.

Their heirloom-grade keyboards of solid maple and with sculpted keycaps are unique to the eye and to the touch, but that’s only part of the Keyboardio story. Jesse has moved further down the road of turning a project into a product and a product into a company than most of us have, and he’s got some insights about what it takes. Particularly in climbing the learning curve of off-shore manufacturing, which will be the focus of this Hack Chat. Join us to learn all about the perils, pitfalls, and potential rewards of getting your Next Big Idea manufactured in China.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday July 10 at 12:00 PM Pacific time. If time zones have got you down, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

Like modular synths? Sure you do, and you need another hole to throw money into! For the last few months, Supplyframe has been hosting synthesizer and electronic music meetups in San Francisco. This week, the HDDG/Piqued meetup will have a great talk with the creator of VCV Rack. VCV Rack is an Open Source, virtual, modular synthesizer — basically a bunch of Eurorack modules inside a computer and it costs a whole lot less. The talk is this Thursday evening in SF. You should come!

The W600 is a new module (you can get it from Seeed, although it’s produced by Winner Micro in various formats) that is basically an ESP32, except it uses an ARM Cortex-M3 instead of a Tensilica core. [ultratechie] recently got their hands on one of these modules and got started with MicroPython. This seems like a capable module and it’s only three dollars, but will that be enough to catch up to the ESP32?

Purple gorilla enters art gallery. At the Het Nieuwe Instituut in Rotterdam there is a new exhibit featuring the, ‘destructive beauty of the computer virus’. The curators are detailing the historical progress of the computer virus from innocent DOS viruses to Melissa to Stuxnet and ransomware.

USB C has been around for a while, but 2019 is the year everything started to become USB C. Case in point: the Raspberry Pi 4. The only problem is that the Raspberry Pi Foundation messed up their implementation of USB C. Not a problem, because here’s how you design a USB C power sink. Basically, you give each CC line its own resistor. Don’t even think about it, just copy the USB C spec. You don’t know more about USB C than the people who designed it, and you’re not really saving a ton of money by deleting one resistor. Just copy the spec.

Teardown 2019: A Festival Of Hacking, Art, And FPGAs

July 3, 2019 by Helen Leigh 7 Comments

As hackers approached the dramatic stone entrance of Portland’s Pacific Northwest College of Arts, a group of acolytes belonging to The Church of Robotron beckoned them over, inviting them to attempt to earn the title of Mutant Saviour. The church uses hazardous environments, religious indoctrination, a 1980s arcade game and some seriously funny low tech hacks to test your abilities to save humanity. This offbeat welcome was a pretty good way to set the tone for Teardown 2019: an annual Crowd Supply event for engineers and artists who love hardware. Teardown is halfway between a conference and a party, with plenty of weird adventures to be had over the course of the weekend. Praise the Mutant! Embrace Futility! Rejoice in Error!

For those of us who failed to become the Mutant Saviour, there were plenty of consolation prizes. Kate Temkin and Mikaela Szekely’s talk on accessible USB tools was spectacular, and I loved following Sophi Kravitz’s journey as she made a remote-controlled blimp. Upstairs in the demo room, we had great fun playing with a pneumatic donut sprinkle pick and place machine from tinkrmind and Russell Senior’s hacked IBM daisywheel typewriter that prints ASCII art and runs a text-based Star Trek adventure game.

It wouldn’t be much of a hardware party if the end of the talks, demos and workshops meant the end of each day’s activities, but the Teardown team organised dinner and an afterparty in a different locations every night: Portland’s hackerspace ^H PDX, the swishy AutoDesk offices, and the vintage arcade game bar Ground Kontrol. There also was a raucous and hotly-contested scavenger hunt across the city, with codes to crack, locks to pick and bartenders to sweet talk into giving you the next clue (tip: tip).

Join me below for my favorite highlights of this three day (and night) festival.

The 50th anniversary of the first Moon landing is rapidly approaching, and uber space-nerd Adam Savage is in the thick of the celebration of all the amazing feats of engineering that made humanity’s first steps out of the cradle possible. And in a grand and very hacker-friendly style, we might add, as his Project Egress aims to build a full-scale replica of the Apollo 11 Command Module Columbia’s hatch.
