I think you would find it very difficult (read, impossible) to buy and assemble the parts for the cost of buying the fully assembled article. especially once you buy in bulk which would get the shipping costs right down. And remember, you would still have to pay import tax on the parts. The Foundation don't make much profit on each board, and neither do the distributors.j_p wrote:Hello,
I would like to know if we are allowed to obtain the schematics of Raspberry Pi and build our own units. I'm waiting for my own rpi, but I'd like to buy units for public schools in Brazil, and I'm not sure we'll have enough money, if we take into consideration shipping and import taxes. We could, however, buy components and assemble our own units here (as far as I understand the Arduino project allows people to do this; I do not know how it goes for the Pi). Of course we'd do whatever the foundation wants regarding trademark (include it, add a "unofficial unit" tag, or whatever else).
Thank you very much!
While you keep using caveats like "almost impossible" people will still believe that armed with a soldering iron, a good eye and a wet Sunday afternoon with nothing much to do, they would be able to knock one out. These are people who have never seen one. The Pi is really, really small and there are hundreds and hundreds of connections. The pcb really is the size of a credit card and you really do need hundreds of thousands of pounds worth of computerised kit in a proper factory to manufacture them.jamesh wrote:Cases would be fine - you can do what you like there, and all the classroom stuff you mention.
Soldering is almost impossible as the parts are absolutely tiny and use BGA's which require ovens rather than soldering irons.
There are, but they typically don't have all of the features of the Pi (such as HDMI output, RCA composite video output, and etc) and are typically have less CPU and less RAM than the Pi. Unfortunately, if you try to build something with specs approaching the Pi, you'll quickly find that you're going to spend *a lot* more money than you would if you simply bought a Pi.grumpyoldgit wrote:Having said that, there must be designs out there for hobbyists to build a computing device on a pcb.
