Did anyone ever get an original Raspberry Pi? All I've seen is pictures of it next to the words "out of stock".
- RobotCaleb 14y ago
  I have two. Neither of which have seen power. Too many other projects going on.
  - freehunter 14y ago
    You have two you've never used, while I have 20 week shipping delays for one unit ordered six months ago, and a heap of schematics and already-wired modules to plug into the GPIO sitting uselessly, and a head full of further designs yet. Goodness. I need to go for a walk. This thread is threatening to get the best of me.
    - antoko 14y ago
      I feel bad for you. Where are you located? If it is in the continental US I'll send you mine. I installed debian on it and did nothing else due to other commitments. I really don't know when I'll have chance to start playing with it.
      - freehunter 14y ago
        I couldn't ask you to send me your RPi. I've put all that stuff in a box under my workbench and moved on to new Arduino projects. Someday maybe my RPi will show up out of the blue and will be a nice surprise and I can pull that stuff back out, but if I got it tomorrow it would likely end up like yours. I've just moved on for now.
- whyenot 14y ago
  Yes. I ordered one in late July from Element14. It arrived about 2 weeks later. I currently have it connected to a webcam and running on solar power.
  - re_todd 14y ago
    That sounds very cool. What kind of solar power product are you using? Where can I buy one online?
    - whyenot 14y ago
      I'm using a 20w instapark panel I bought through Amazon.
  - ajays 14y ago
    Do you have a description of your setup? It sounds interesting.
    - whyenot 14y ago
      Sure! I am still experimenting and changing things around, but here is my current setup. 12v 10Ah sealed lead acid battery Instapark 20w solar panel with solar charge controller Pololu step down switching regulator Logitech c270 webcam (USB) Edimax wifi dongle (USB) With this setup I am running 24/7 "off the grid." We'll see how well it works in the winter. The webcam and wifi can be directly connected to the RPi. You don't need a powered hub. This greatly simplifies things. The goal is to eventually swap out the SLA battery for a 12.8v LiFePO4 and house everything in a waterproof enclosure made from a Pelican case. I also have a powered hub and a GlobalSat GPS unit that I'd like to add at some point. The logitech camera is not that great. I'll look into replacing it once we know more about the add on camera coming from the Raspberry Pi foundation.

      Bear in mind there apparently some nasty hardware limitations in the USB controller that tend to make USB webcams unreliable: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=28&t=12097 http://www.raspberrypi.org/phpBB3/viewtopic.php?f=28&t=1... I'm guessing that whyenot dodged them due to a combination of luck and not having any USB peripherals connected other than the webcam and Wifi adapter; the more USB devices, the more likely you are to run into a problem.

  I haven't received mine. Ordered 17 July 2012, despatch expected within 11 weeks but still no feedback from RS.
  - sounds 14y ago
    This is really a shame. Another commenter says the same and apparently it turned him off to the RPi in general. I don't know why RS drops the ball on some orders; hopefully as demand increases another supplier will start offering them for those of us who dislike RS.
- petepete 14y ago
  I did, after rather a long wait (I ordered in early May, and it came in early July). After the excitement wore off I installed OpenELEC and it now sits in my front room, working pretty damn well as a media centre.
- freehunter 14y ago
  I ordered mine the day after it went on sale. Two months ago I got am email saying it was being shipped out and should be here within 12 weeks. Last week I got an email saying it was delayed another 8 weeks. This really depresses me that they're talking about Rev1 production coming to an end and Rev2 production ramping up when they can't even fulfill their existing orders.
  - yardie 14y ago
    Good God! who did you order from? I placed an order with RS in May and got it about a month later. 20 weeks is simply unreasonable. I'd cancel and look at another fulfillment company.
    - freehunter 14y ago
      I ordered from RS. At this point, I don't even care anymore. I won't be doing business with them again, and I likely won't ever order another RPi. I was terribly excited for it, but it's been so long since I put down the commitment that the thrill is gone. My cousin ordered a couple weeks after I did and he got his in June. I've just doubled down on Arduino instead.
      - eckyptang 14y ago
        This is normal for RS. Back in 95 when I was doing EE, we ordered 2000 low dropout regulators for a production run from RS. I left the company in 1998. In 1999 I got a call from one of my colleagues and they'd received them... Needless to say their invoice and stock was returned.
    - X-Istence 14y ago
      I ordered mine from RS on July 2nd... looking at their shipping tables that they have now posted my order number is not going to ship till mid-November.. This has saddened me greatly and has made me angry. My friend ordered from Allied Electronics and got his within a month.
      - 14y ago
- oliwarner 14y ago
  Yeah they've shipped tens of thousands of them.
  - asb 14y ago
    Hundreds of thousands.
- archangel_one 14y ago
  I put my name down around June/Julyish, it was delivered in early August. Surprisingly faster than I expected.
- tlrobinson 14y ago
  Yeah, I got 3...
- abecedarius 14y ago
  I ordered one in August, that arrived a few days later. Just luck? It was out of stock every time before.
- ori_b 14y ago
  I ordered two about 3 weeks ago from Element 14. They arrived near the end of last week, so about 2 to 2.5 weeks for order fulfillment.
- sliverstorm 14y ago
  I've got one, I've had it for months now.
tomstokes 14y ago
The mounting holes alone make this new revision worth waiting for. It's also nice to see the additional GPIO output which can be used either as an additional I2C bus or used for I2S (digital audio) output. The latter should be very useful for those who want to use the Raspberry Pi as a media center PC as it's trivial to convert I2S to S/PDIF or Toslink (optical). Finally, I'm glad the GPIOs have been changed to expose the missing JTAG debug symbol. Having proper JTAG support makes low-level development far, far easier.

It's such a shame that the guys at Raspberry Pi can't communicate very well. This is fantastic news, but where's the picture? the schematic? There's a massive thread on the future Camera Module. Once a day or so, someone says "Can we have an update please?". The response: "In Development." Snooze.
- kasbah 14y ago
  I think they are doing a very good job considering they have one full-time employee.

Update from Allied: They are currently 10 weeks backlogged.

"The SMSC 1V8 power has been disconnected from the system supply." I notice they don't talk about this much at all, or give credit to the person who figured the issue out (who I believe may have been banned from the official forums for talking about it). It turns out that the high temperatures some people were seeing on the LAN9512 chip weren't actually normal at all; they'd screwed up and connected the output of its internal 1.8V regulator, which wasn't meant to drive external circuitry, to the 1.8V rail. So on some boards (depending on tolerances) its internal regulator ended up providing the 1.8V supply for the entire board and overheating quite a bit.
- X-Istence 14y ago
  Do you have a source for this? Also is there something that owners of older boards can do (such as cutting the trace?) to make sure their boards don't overheat?
  - makomk 14y ago
    There's an entire thread about it on the Element 14 forums here: http://www.element14.com/community/thread/19236 http://www.element14.com/community/thread/19236 Unfortunately, unlike some of the other modifications in newer board revisions, there's no easy fix for this for owners of older boards. The level to which boards are affected varies and it's not clear how many (if any, for that matter) have stability problems as a result. Doesn't help that most people don't actually seem to report when their board doesn't work properly, in part because the moderators on the official forums are quite hostile to anyone mentioning problems.
