There are no ventilation or cooling requirements. This has been verified by an RPi admin here.

Yes, under usual circumstances it should be possible to run the Raspberry Pi in an airtight case. I have measured some temperatures confirming that there is amply thermal headroom. For reference: 22°C room temperature 42°C idle I ran sysbench to stress the CPU: sysbench --test=cpu --cpu-max-prime=20000 run 45°C 20 s 46°C 2 m 47°C 5 m 48°C 12 m Since ...

There's a short piece that includes Pi 3 benchmarks over at the PiMoroni blog. All of the benchmarks below were carried out with just a USB keyboard and mouse connected with power supplied from the official Raspberry Pi Power Supply, with the exception of the WiFi dongle test in which the USB WiFi dongle was also connected. The Pis were naked, i.e. ...

When shutting down the HDMI and USB on the Pi3, the current drops to 160 milliAmps. In my tests, this was roughly 200 milliAmps on the Pi2. Thus, shutting down hardware (if you don't need it), can be a huge energy saver. Update: Use this command to turn HDMI off: /opt/vc/bin/tvservice -o And this command to turn it on: /opt/vc/bin/tvservice -p Use this ...

tl;dr: Those models that have holes in the PCB are made for M2.5 (or UNC 3-48) screws and a length fitting to the enclosure or respective counterpart. Pi 1 B+ contains four M2.5 mounting holes - supposedly drilled to 2.75 +/- 0.05 mm. This information is taken from the "Raspberry Pi B+ Mechanical Schematic" (official drawing by J. Adams, 07/03/2014, to be ...

You definitely want to keep it away from any conductive surface, to avoid damaging it. I am currently awaiting a case from adafruit.com . In the short term I have run it on an antistatic mat, and now it is in a lego case I created from my nephew's collection of legos (similar to this one).

Since everything on the board is 5V and below you would need to have a very low skin resistance to even transfer enough energy to cause any interference on the board let alone shock you in any way. You might not want to try to licking it, but touching shouldn't be a problem. You generally don't get a shock even from 9V and 12V batteries (unless licking is ...

The easiest and cheapest case must be The Punnet; it is a case made from cardboard. You can download a PDF, print it onto your favourite coloured cardboard, cut it out and stick it together.

Below are the results from an experiment examining some properties of the Pi in a rough and already mostly sealed enclosure. The ambient temperature was 30C, the blue dashed portion of the graph represents the time from power up of the Pi until it had reached thermal equilibrium whilst in idle mode. The second, red, portion of the graph is the temperature ...

Should be fine. Antistatic bags are very slightly conductive, but I doubt you can affect the operation of the RPi with it. They are typically made from PET which has a melting point of 260°C which is somewhat higher than the lead free solder 232°C, so if you are melting the bag you have other problems! I used mine in the cardboard box is came in (from ...

Adafruit have made an Acrylic snap-together case, available here. There are numerous cases available on eBay, see this listing for an example. You can also make a case out of lego, see here You can also print a case out of paper, see here PI-STACK® (ebay)(hi-res) Pibow

VHS-Pi (Credit to Maarten) as a case - built as a portable media server (when visiting friends) Includes: -RaspPi (duh) fully un-modified with the following directly connected --Ethernet 'break-out' cable --Audio 'break-out' cable (not fully completed yet) --5v Supplied over GPIO -7-Port D-link Hub (4 ports exposed, 3 for internal use) --Wifi dongle --...

Stay away from conductive surfaces, such as metal, it is very likely to damage your Pi and possibly other devices attached to the Pi. I frequently recommend a piece of paper as a useful surface for running circuit boards on, but that is only a short term solution, something resembling a real case should be purchased in the long run.

I have a 3D printed case. If you know anyone with access to a 3D printer, there are a variety of case designs freely available on thingiverse. I'm also in the midst of a case mod project to put my Raspberry Pi inside of a Sega Genesis cartridge. I'm also planning to use the box that the cartridge came in as an additional carrying case, as well. However, ...

More information on this will be available as and when the units start arriving with purchasers and we get a clearer picture of overclocking capabilities and such. To the best of my knowledge the figures from the benchmarking done by the pimoroni.com blog are accurate: In terms of CPU temperature, the Raspberry Pi 3 runs significantly hotter than the Pi ...

For me: The pins, headers and external components look fragile and easily bent. It looks easy to accidentally short GPIO pins and other conductors on the Pi by (e.g.) dropping it on a coductive surface, brushing a conductive object against it or dropping a conductive object onto it while it is powered up. a number of the sockets, the HDMI connector in ...

Of course, if you have any Lego hanging around that's another easy solution. In fact, there was an article on the front page of the Raspberry Pi homepage detailing just that: http://www.raspberrypi.org/archives/1354

So far I just keep it in the box it came in from Farnell. You can cut holes for whichever ports you are using.

I'm looking at getting a professional case ordered, but in the meantime I built one out of Lego. It works surprisingly well at being effectively a prototype case, and it allows you to easily keep spaces open for ports.

If you look on the Raspberry Pi Wiki Resources, under Documentation you will find 3D CAD files: RPi Model B 3D CAD files Theses are various 3D CAD Versions in both RAR and ZIP. CATIA V5 RAR CATIA V5 ZIP ProE RAR ProE ZIP STEP RAR STEP ZIP SketchUp SketchUp8 Eagle 5 I would say those are the "official" 3D CAD files. You ...

No conductive surfaces - you run the risk of short-circuits. I put some stick on feet on mine and stand it on a piece of paper. You could box it in paper too

Some type of case is the best protection from drops, spills, things falling on it, accidental contact, static electricity and dust. Having said that the price, durability, and protection provided by a case varies tremendously, as evidenced by Gnibblers low tech approach to the Pibow, discussed on the Raspberry Pi site earlier this week. If you intend to ...

I was only able to find this on Google. It should work for the RPi 2. It's in a PDF form instead of a nice SVG, but it looks like it could fit what you need.


6

Think of it as any other computer, you can but shouldn't, even if you were to suspend it by its wires the dust in the air could damage the board.

I reckon the best case is The Punnet; it is a case made from card. You can print it yourself, fold and glue, and you will have a case in minutes. It protects the RPi from dust, which is the main threat. Other cases may protect the RPi from light spills or unwanted electrical interference, but I don't think it is worth it given the cost of the RPi!

Many cameras and video cameras have waterproof cases available, most of these have buttons on the outside connected to mechanisms for pressing buttons on the actual contained device. As other answers have mentioned, waterproof cables with underwater connectors do exist, the problem you might face however is that the off the shelf waterproof casings probably ...

The rev. 2 model A and B both have a breakout for a second I2C bus, with the caveat that you can't use it and the camera header at the same time (this is software switchable while the pi is running). The eight hole breakout is easy to see just inside of the GPIO header. This is usually referred to as the P5 header in documentation, but on one (of two) of ...


6

I am sure it will be fine. The newer zero obviously has the same footprint when viewed from above, judging by the placement of the screw holes in relation to the GPIO breakout. The camera connector is laid on its side. Although there's no picture besides a top shot on the Foundation blog post, in this Adafruit image: It is appears that the connector, at ...

I'm going to be bold and just say no! While it's true some big capacitors can retain their charge and shock you, there's none nearly big enough on the Pi for this to happen, and I don't believe there's anything on the Pi that runs much above 5V anyway. Definitely not at a voltage that could shock you!
