Huge archive from Project Apollo now on Flickr

October 2015

Years of hard work, curation, and archiving have brought the Project Apollo Photo Archive to a Flickr album. Kipp Teague writes,

“This new Flickr gallery would have not been possible without the support of Mike [Gentry], Steve [Garber], and Eric [Jones], and many others.”

In this note, he corrects a misconception that this archive itself was an NASA undertaking. While the photos come from NASA, the archive is an independent effort.

There is also a Project Apollo Archive Facebook page, in addition to the photos on Flickr.

The latest video from AsapSCIENCE, The War on Science, addresses the preverbal war between science and society we are experiencing today. 100, 200, or 1000+ years ago you could argue the ignorance of science was due to lack of information availability. However, that does not apply to today’s world. The entire World’s knowledge and the sum of collected data are available to virtually anyone, anywhere at any time. This moment isn’t just historical; it is pivotal. Yet. Society as a whole seems to continue the trend of ignoring this data in favor of emotional social media posts.

AsapSCIENCE’s take on the situation is spot on and worth not only the 5 minutes to watch but also sharing with the video everyone you know, and voting to support science, in your area.

Elegant and cheap storage solutions for your shop

lattice as shop storage

The article caught my eye because I’m about to make a move, and I’ll be setting up my shop soon. Seeing these clever alternate uses is already giving me some ideas.

The perfect shop doesn’t need expensive storage options. While there are stores dedicated to containers, they to tend to run on the expensive side. A workshop, may not need the most expensive storage gear. Especially if it gets as dusty as mine! This Make article offers 5 Simple Shop Storage Solutions.

Another resource for shop hardware is Episode #92 of The Engineering Commons podcast, “Garage Gear.”

Hackaday SuperConference Call for Papers

hackaday superconference 2015Hackaday is holding their first conference! The conference plans to offer workshops covering hardware, engineering, creativity in technical design, product design, prototyping, and (of course) projects.

The conference is being held in San Francisco on November 14th and 15th, 2015. You can find out more about the SuperConference here.

They have a call for papers out, which you can find in this Google doc.

Personally, I’m pretty excited. I’m moving to the Bay Area the first week of November. So in a way, it’s like Hackaday is throwing me a party! j/k

How Arduino digitalWrite Works – and why AVR is Faster

Crash Bang Prototypes

Arduino digitalWrite speedPreviously I looked at the speed difference between digitalWrite and direct port manipulation. It was a chance to check out a Saleae Logic Analyzer. Andrew at !Crash-Bang Prototyping took the analysis a step further. He broke down what is going on inside of digitalWrite().

This study is useful. When you’re ready to move beyond the Arduino IDE or the core functions, you can decide if you need your own version of digitalWrite().

Check out !Crash-Bang Prototyping’s “How Arduino digitalWrite Works – and why AVR is Faster“.

Deck out the rest of your Ghostbuster gear with a Ghost Trap. Dustin McLean from DIY Prop Shop from AWE me builds a trap in this quick 12-minute video. The build uses very basic materials: cardboard, popsicle sticks, tape, PVC, and spray paint. Of course, the tools used are just basic cutting and straight edges.

If you aren’t familiar with DIY Prop Shop, the show–as the name suggests–takes a DIY approach to building famous movie props. Totally fun to watch and get ideas for your projects.

Check out the Ghost Trap Build on YouTube. Who you gonna call?

EngineerDog explains why stressed plastic turns white

Ever notice when you over-stress plastic, the stress points tend to turn white? The color or type of plastic doesn’t seem to matter, does it? So what is going on? This awesome post from EngineerDog explains why stressed plastic turns white.

If you’re starting to work with ABS on your 3d printer, it will help to understand what is happening to the polymer chains. It’s a process called crazing.

One good reason to learn about crazing is there is a way to fix it. So check out EngineerDogs’ explanation for more.

My Modular Soldering Station for the Space Limited

modular soldering station

Solder is the glue of electronic circuits. In addition to a permanent mechanical connection, solder provides an electrical connection. Not too much unlike glue solder combines two separate metal pieces with a bonding material. In this case, the bonding material is a metal or allow with a relatively low melting point.

When soldering together a circuit, the quality of the solder joint is crucial. Most people probably recognize the need for a high-quality soldering iron, like the FX-888D from Hakko, but about the other tools?

Building a modular soldering station is just as critical to making good solder joints as the actual solder itself.

Capacitor lifetime depends on the materials capacitor lifetime

Although not all applications are safety critical or mission critical, reliability is still a vital consideration for many electronic products. Making informed choices at the part selection stage can help ensure the product will perform correctly over its intended lifetime.

When choosing capacitors, properties such as volumetric efficiency, frequency stability, temperature rating or equivalent series resistance are often the primary factors that govern technology choice. In these cases, understanding factors affecting lifetime can help engineers make sure the product will deliver the required reliability.

On the other hand, a long operational life may be an essential requirement of the end product.

Corner Case: 90-deg turns for WS2812
NeoCorner from

If you’re working with the WS2812B and need to turn corners, you’ll want to check out this NeoPixel Corner adapter PCB from It’s a pretty simple board. I came across it as a solution for an upcoming lighting project.

In josh’s example, he used a CNC to mill the PCBs. If you’re using one-sided FR4, that might work well. You’ll want to double-check thicknesses if you want to use OSHPark or similar.

You can check out the full write-up here or the NeoPixel Corner Board project GitHub.
