Yavin Thruster Sprint 1

Mach 30 has started to use agile methodologies to manage its engineering projects, and the first of those to use an agile approach is the Yavin cold gas thruster. This last week, we completed our first sprint, and we’re all very pleased with the results.

For anyone that might not yet know about the project, it’s to develop a test stand connected to a source of pressurized gas, such as an air compressor, where different designs for the thruster can be tested. One of the aims for the project though is to develop and test new tools for future Mach 30 projects, such as CadQuery and our new Mathematics Tool Kit (MTK), a piece of software to make it easier to compile documentation around science and math proofs and analyses. We’re not only working to further develop these tools, but putting together a tool-chain for future design efforts. How this tool-chain works for Yavin is that we’re using MTK and a Python library to document and calculate aspects of the thruster such as wall thickness and nozzle shape. We can then create models with the same library in CadQuery, and export the model to be 3D printed.

In the first sprint, we took on 3 main items. The first of these was an export control review of the project, which can be found under the project’s Wiki on Open Design Engine. Second was a structural analysis of the gas chamber before the nozzle. The team generated a number of artifacts for this, including a document created with MTK detailing the analysis, a python library to support it, and an initial model created using CadQuery. You can see pictures of the model below, but the coolest part is that we printed it!

This is just a proof of concept model though (it’s huge, and not an ideal size at all!). There’s a lot more work to be done! We have to produce another (or add to the existing) library to do the actual thruster design, and a number of other tasks.   Some work to do to make it so that CadQuery supports all the functionality we’ll need for making a good performing nozzle, but we also have a number of tasks ahead focused around testing.

For transparency, there’s one more item we had planned on doing, and that was performing a test calibration on a volunteer’s 3D printer.  Doing so helps us to build up information about how to calibrate other printers for printing future Yavin thruster nozzles. We don’t just intend for Mach 30 to print these, we intend for all sorts of people to do so, so we’re trying to make it as easy as possible on our end to print one of these.

We feel we accomplished a great deal for our first sprint, and we’re all very proud. If you care to hear more about our first sprint, you can check out our sprint review and retrospective here.

June 2015 Reports Hangout

This month, we continue our new round table discussion about what’s going on with Mach 30, as well as Space, Open Source Hardware, and the Maker Community. Mach 30 positions itself in the middle of these 3 communities, and this month we definitely talked about all of them. There’s space news, open source hardware community developments, and of course details about our ongoing efforts to make mankind a spacefairing civilization.

One of the big topics is the Yavin cold gas thruster, Mach 30’s Open Source Hardware project focused around the development of a number of tools and technologies that will enable not just greater projects here at Mach 30, but also in the Maker and OSHW communities at large. Another big topic is our upcoming Apogee II conference, our second yearly conference were we engage with the community about what we’re doing, what our plans are, and the community’s input and participation in that, from Space Enthusiast to Maker to Open Source Hardware fan. One particular point of note is our plans for doing a bake off of user interface development tools for projects, which are designed specifically with the maker community in mind.

There’s plenty more, so check out the ~30 minute video for more!

Many of these topics from this month will have periodic updates. Naturally they will be covered in the new and improved monthly reports hangouts at Mach 30, so subscribe to our YouTube channel to STAY TUNED!

Mach 30 Reports Hangout for May 2015

What was Mach 30 up to over the past month? Find out with the May 2015 Reports Hangout.  You may be familiar with the (not so) new round table discussion format where volunteers discuss current events in space, making, and open source hardware.

This month, we reminded everyone why there was no Report’s Hangout in April and mention a few topics that we would have covered if there was: the 2014 Mach 30 Annual Report, Mach 30’s plan for the remainder of 2015, and introduction of the Yavin Cold Gas Thruster & the Apogee 2 Event.  Then we dove right into all of the current events regarding rocket, launch, and space-related events.  Finally, we celebrated the 25th anniversary of the Hubble Space Telescope in a very Maker-y way…  Check it out the video below to see how!

Hot off the presses: The Mach 30 2014 Annual Report

We are proud to announce the publication of Mach 30’s 2014 Annual Report. This publication is Mach 30’s first annual report.  It highlights all the great stories from last year. Publishing this report is an important step for the organization because it signals a new level of maturity and demonstrates our continued commitment to our our open source values.

While it’s not a legal requirement, most established nonprofits publish annual reports to share their accomplishments, successes, works in progress, and project close-outs while setting the stage for the future plans and operations. As Mach 30 matures, we want to follow this best practice. More importantly, documenting our work is at the core of Mach 30’s values including transparency and the use of open source methods, even at this organizational level.

This report covers our progress in open source spaceflight hardware, our first conference, our contributions to the Open Source Hardware movement, and looks forward to the work coming in 2015. 2014 was a momentous year full of firsts, and this first annual report is one more milestone along our journey. We look forward to many more to come.

Mach 30 Update for March 2015

This post was co-authored by Mach 30 volunteer Aaron Harper.

The Mach 30 Reports Hangouts experiments have continued in February and March.  Our new format is a round table discussion of current events in space, making, and open source hardware, with a focus on events happening at Mach 30.  This new format is paying off and the result is this month’s reports hangout is well worth the time required to watch.

This month, we have a report on Alicia Gibb’s book Building Open Source Hardware in which some Mach 30 members and projects are featured. We had some HUGE news in the form of contributions to open source design software and great strides on simplifying export control compliance for open hardware projects.  Check it out below.

For those that prefer a written update on the status of Mach 30 projects, you can still check out the March Reports page on Google Drive.  Many of these topics from this month will have periodic updates.  Naturally they will be covered in the new and improved monthly reports hangouts at Mach 30, so STAY TUNED!
