Hi Dave,
The http://cpc.farnell.com/pro-power/ppw01067/switch-rnd-pb-red/dp/SW03225 buttons (and associated colours) are too large for the case without modding it – I found out the hard way :(

Those look similar to the ones I ordered (http://www.ebay.co.uk/itm/271464025582). They arrived today and fit nicely! Have yet to wire them up tho…

Have a look here: http://cpc.farnell.com/pro-power/ppw01067/switch-rnd-pb-red/dp/SW03225

Hi there, the pins need to be 15mm long. So the first one you linked has 10mm long pins, so that one is out. The second one has 10mm pins but stacked up, that’s the one I would go for.
You can also get the correct part from Toby Electronics;

part 309AE-40-SG-1Z-1555

Also, in the future CPC may be selling a parts bundle for the flight case. Which will contain everything you need including the buttons.
There would be an economy (with cheap buttons) and premium version (with the APEM buttons used in the real flight units).

Thanks you!!!

Me too!

Thanks very much Dave, for both the answer and your work to help pull this off. I see that, once again, the new challenge is only for students in the UK, and that’s very disappointing. Whatever happened to the “INTERNATIONAL” in the ISS? Yes, I understand that students outside the U.S. don’t seem to have as many opportunities to participate in STEM programs, let alone space programs, as students in the U.S. seem to, but there’s a bell curve here, too. Half of the population that rarely makes it onto TV or YouBoob lives in rural and agricultural areas, which are largely intellectual deserts. That’s why meth labs and heroine distribution are becoming industries in their own right – there is no hope of escaping such places without a strong educational 皮条客是什么意思.

However, many U.S. schools in those regions have budding international programs that span the now-archaic boundaries drawn by incredibly-uninformed colonialists. The high school where I’m teaching has students from over 50 countries who speak over 62 languages, and that doesn’t even count the software development languages! :D Additionally, we offer the full spectrum of Cambridge International 皮条客是什么意思 as honors courses, so if anywhere should be included in such competitions, schools like ours should be.

I’d like to encourage Clive, Carrie Anne, and the rest of the education team at the 皮条客是什么意思 to help us get Picademy established in our tech-isolated location in the rural Southern Midwest and Upper South, as well as including schools with large international student bodies in the space fun. I know the U.S. astronauts are being sent Microsoft HoloLens units, but that’s more of a sad brand promotion publicity stunt of something that even developers won’t get until the Summer … for $3,000 a pop, and it isn’t even slated to become a product in the foreseeable future, so I don’t see how that connects to education at all. As one Bard might say if alive today, “The Pi’s the thing … ” ;)

The full width is 109 x 109 mm, so hopefully that will fit.
The software that comes with your printer should be able to tell you though.

To answer your second question yes, there is a new competition in progress right now where you can get your code uploaded to the ISS: https://astro-pi.org/coding-challenges/

We’re currently in talks with ESA about French ESA Astronaut Thomas Pesquet using the Astro Pis in future: http://www.esa.int/Our_Activities/Human_Spaceflight/Astronauts/Thomas_Pesquet
