Post by thread:[OT] My Raspberry Pi has arrived.

The only annoyance at this moment is, no screw holes, so it's either by a box or maybe 3 sticky feet will do the job. Sockets are stiff and as someone has already done, it is very easy to unmount the electrolytic (C1) when removing the power cable, there is a tendency to hold the little blighter to gain leverage. I'm mulling over getting hold of a TI HDMI/DVI to RGB converter chip (I think it's a TFP410 or TFP401) and then I can drive a standard LCD monitor raw panel. PCB would be a nuisance though, TI recommend 4 layer with complicated ground planes and it's a 100 pin mini TQFP, perhaps not doable after all. Colin -- cdb, on 24/04/2012

According to Electronics Weekly, there are over 100,000 confirmed orders for the Raspberry Pi, and they can confirm all those ordered before 18 April will definitely receive their Raspberry Pi before the end of June 2012. Element14 claim customers in 30 countries have received boards. -- Scanned by iCritical.

JPEG is a perfectly acceptable format for posting photos on the net. png is a lossless format primerally intended for line-art and similar

PNG compression is simply not optimised for photographic images and tends to produce relatively low compression ratios on them. If you need to make a photo smaller and still keep it accessible to most people you have basically to choices, lower the resoloution or lower the jpeg quality setting. > - doesn't solve th eproblem why Windows Paint, Windows > Photo Manager all manage to convert jpg to png and manage to make it an > order or two of magnitude larger. Doesn't sound too unreasonable for me. You may find different png encoders vary a bit but i'd be very surprised if any of them come close to the size of the original JPEG

In general: PNG is lousy for photographic stuff. It will be very large for continuous tone images because it can do little, if any, compression. JPG is lousy for line art stuff. It will generate weird looking artifacts around high contrast areas of the image. Horses for courses. -- Bob Ammerman RAm Systems {Original Message removed}

PNG is not optimized for photos. And attaching it here is not a really good way to post :( An image upload site is best

Huzzah. Albeit 2 months from now. ____________________ Farnement 14 escrit: Dear Russell, Having successfully passed its CE compliance testing, we can now confirm that your Raspberry Pi will be dispatched week commencing 25-Jun-12. While you wait, we'd like to offer you the chance to get everything you need to get started with your Raspberry Pi for 15% OFF!

It is a strange list that they have. I take it that will not be your primary source of SD memory cards. For someone to have a lot of time to prepare they do not have the products or quantity of products I would expect. Raspberry pie could have been a game changer and may still be but so far has significantly under performed expectations. I may have missed something but detailed software tools and application specs should have by now been widely available and promoted w..

They are way out of touch on the SD card pricing and yet before they made the page unavailable on the AUS site the accessory bundle was priced at AU$29.95 which consisted of all the cabled and a 4GB SD card. Here in Ozland I purchased a class 4 Toshiba 4GB full size card for $3.00 from my local computer shop. Tricky Dicky (Dick Smith Electronics) want AU$ 29.99 for a USB-A to micro B 1.8m cable whereas E-14 are only asking $ 1.00.
