Re: Meet Raspberry Pi Zero: the $5 computer

This definitely has awesome potential once USB type-C becomes ubiquitous. Right now the additions of adapters for basic desktop computing tasks make it a bit more clunky than it would originally appear. Embedded users will have a great time with it though, since they can skip the disadvantages of the compute module (fixed mmc, carrier board etc.).

Nicely done :)

I have just some questions: Am I right that the (unpopulated) TV-Pins are for Composite output like the Cinch jack on the "older" Raspberry PIs? :?:
Yes (I had to look up "Cinch". )
And which Purpose do the 'Run'-Pins have? Do they work as Reset- or Shutdown-Pins? :?:
A hard reset, the same as on the A+/B+/2B

JTAG: that's for our testing; not much you guys can do with it. You'll find the same thing under the HDMI port on other Pis.
Composite: yes, that's what those two TV points are for.

I've seen one review mention this is a limited edition Raspberry Pi of limited run.

Is this correct?

VisualPi,
Need new faster OS; All the Linux is too slow.
I'm curious. In what way is Linux too slow? What are you trying to do? Is there any other workable OS that is faster for what you want to do?

If you want slow run Windows. All Linux systems on equivalent hardware are orders of magnitude faster than Windows.

If you're going to claim Linux is too slow you need to back that up with some empirical statistics (not bench marks, because they are always optimised for the hardware they're trying to show off).

No, it's not limited edition or a limited run. They may be referring to the fact that we don't have an infinite number in stock at the moment!

What is slow is all the crude that major distributions seem to include no matter what you do. Well, not no matter what you do, but the second you start using their apt-get thing or whatever, it drags in the kitchen sink. But I don't want the kitchen sink and I don't want the toilet either.

The RPI Zero has got some good reviews. The RPF are going to kill off the Pi clones.

stderr,

I minimal install of Raspbian or Debian is not so huge.

If you install program A that needs libraries X, Y, Z to work then that is what you get. No way around that is there? It's up to you what you install.

This has nothing to do with speed though. Even if the default SD card image contains a window system, a desktop, and a pile of crap you don't need, mathematica, scratch etc, that does not mean it's in use at run time. It's only wasting space on your SD. Again it's up to you what you run and how much priority you give it.

Don't forget, there is always "apt-get remove whateverJunkPackage"

And stick a normal one on the end. I believe that would work.
The Swag store, Pimoroni and others are selling the Zero with an (optional) kit with various connectors and adaptor cables for an extra few quid.
Only can buy ZERO with kit therefore goes up to around £12.50 from CPC UK

ZERO MagPi Magazines available locally..

Will have to wait for a $5.00 + P&P..........
Very little chance of getting your hands on a MagPi #40 when you are living outside the UK.
Currently I can only buy the zero as a kit which includes the cables, for Eur 18.95 or GBP 13.31.

A word of warning: the common "right angled" micro usb otg adaptors are the wrong way round to fit the pi as they obstruct the power microusb:

http://www.amazon.co.uk/female-Micro-Ad ... 009DFCCKO/ - 64p ! (wrong)

so unless you plan on powering the pi via gpio, or backpowering usb,
better to get straight or "left angled ones":

I was thinking of when I installed Ubuntu Core and then figured I'd add Firefox. Boom!
If you install program A that needs libraries X, Y, Z to work then that is what you get. No way around that is there? It's up to you what you install.
Does it really need those libraries and other programs? How much is added to Tiny Core to add in Firefox? How much is added using apt-get?

I think you'll find that things are often running, and things that you don't want to run. Why is Apache running? I didn't install Apache!
Don't forget, there is always "apt-get remove whateverJunkPackage"
Will removing something take out the system? I changed the hardware that Linux was running on and it wanted to remove the Nvidia stuff. Fine intention, but it kept blowing up about libc for some reason. Well, I could purge libc, but if I did, it claimed, there would be trouble. I bet. But, of course, I don't want to remove libc, I want to get rid of the Nvidia drives because this system doesn't have an Nvidia card in it!

If only....

The Zero had a normal sized USB connector to accept all those tiny, 2 dollar, USB WIFI dongles and memory sticks etc.

Regain the cost, and space, of that by dropping the annoying USB power connector. We have a header to supply power into.

I guess it the Zero is not targeted at us embedded system/IoT nerds.

Ah well.

Does anyone know if the USB OTG port can be used to power the Pi Zero as well? I plan to use it in client mode (as a slave to another host device over USB) - but I want to use a single cable, power it on the same connection from the host - so do I _have_ to use the second microUSB port or can the OTG one be used for both power and data (in gadget/client mode).

+1 to the full size usb - not alot of room on the board though.

Sales of micro usb otg adaptors will be going through the roof.

I'm stunned they've managed to get to a $5 price point - I'd still have been surprised at $10 !

Yes, I successfully tried that earlier:
