Is the BCM2835 (Broadcom SoC) proprietary to the Raspberry Pi organization?

I ask because assuming someone wanted to manufacture their own (large) batch of RPi's, the major component that would be most difficult to procure is the Broadcom SoC (see here.) If obtaining this chip isn't possible or is extremely difficult, are…

Where can I find the schematics and supporting design documents for the hardware?

I've tried to search for this online, but other than a few posts on the Raspberry Pi blog, I can't find an official source of the design documentation for the hardware. It was my understanding that the entire project is Open Sourced. Is this…

How long did it take them to design the Raspberry Pi?

Is there any published information about how long it took the Raspberry Pi guys to design it to initial production? How many hardware revisions were there? How many engineering hours were involved? What about prototyping costs?

Is there a simulator for building circuits with Raspberry Pi GPIO pins?

I was wondering if there is a free simulator/emulator that I can run either online or on a Windows computer to let me test my scripts and more importantly my wiring, as I am new to building circuits. I also need to be able to build the circuits in…

What are some shortcomings of the board design?

What parts of the board could cause electronics professionals to think it was constructed poorly, quickly, or unprofessionally? Is it simply soldering, a lack of clean trimming, or placement of the components themselves?

Will I damage the GPIO

Will I damage a GPIO (set to input) if introduced to 10V 1mA? I read somewhere that the GPIO ports can tolerate maximum of 16mA I need to detect on/off ( 10V/0V ). Could I possibly use voltage divider?

Is there a way to have USB data transferred from Pi to HAT?

I'm designing a Raspberry Pi HAT that requires USB for debugging. The 40-pin GPIO connector that connects the Pi to the HAT doesn't seem to have any USB designated pins. I would like to use the USB port already located on the Pi to do the debugging…
