content: They're different ... RPi is a small computer at the price of a dev board. Arduino is a simplified AVR dev board. A lot of observers think Arduino is dying due to the noise in the media and retailers trying to make a buck with RPi accessories.However there are an increasing number of alternatives to Arduino out now or coming soon. At the end of the day we're spoiled for choice.

It's the second huge open source thing to happen!" and people are confused on what it is or what it can replace.I can treat the Arduino as an AVR dev board, not sure you can turn the Pi in to some power hungry ARM dev board if you started using it for this kind of stuff...let it stick to the computer crowds and let it do computer things :- )

content: Depends on what you want to do.With the Pi there's a lot of OS between you and the hardware -- with the Arduino, not so much.If you want to build a system with realtime/deterministic responses then the Arduino is going to be a better bet. If you don't need realtime but want lots of high-level stuff then the Pi is fine.One area where the Pi really shines is if you want to create gadgets that have a very nice looking user-interface. With the Pi, that simply involves throwing a $29 LCD screen on the composite video output and writing the code using a high-level language that provides all the routines you need for such things.I'm coming up with an increasing list of test gear and other devices that would work very nicely on the Pi hardware.

Between the Broadcom chipset and all of the resources on the board that are closed source...really, it may be useful for a lot of things, but it is no replacement for much of anything, particularly anything open source.Also, there is this...did Arduino kill off the PIC? Or are people still programming PICs? I can see something comparable developing around a more advanced set of micros, but that still wont kill off Arduino. Or the PIC, for that matter.

content: I have a drawer full of processors boards that do exactly what the Raspberry Pi does except are faster, have more easier to use I/O, aren't poorly designed like the Pi and have more flexible options. Many allow use of Windows OS in addition to linux. I also have a Pi.The Pi is simply an arbitrary price promise for a computer and a long list of compromises to get there.As Tesla said, you shouldn't judge something by it's initial results. The seed of the Pi has been planted. In marketing terms it has "crossed the chasm" from being just a niche product to now being a mainstream product. Now it's time for them or someone else to grow the idea into something that is of better quality.

content: I do not think Raspebbry will ever be so popular as Arduino for these reasons( at least)1.Arduino has a big number of users ( probably because it was before Raspi)2.Arduino is really open projetc. Raspberry is NOT open and particularly Broadcom stops (almost ) everyone, from making very technical projects because of the lack of Broadcom datasheet. ( The one that was posted by Raspi foundation is not what I call a datasheet).3. Not so many existing projects for Raspi as there are for Arduino. And why should I spent time on developing new projects, if there is no support from Broadcom?

content: I like that project, poptones. Thanks for sharing.The points for and against the Pi are both valid. The thing to keep in mind with the Pi is it's rampant success and the success of the "me too" products. This shows a clear demand for such products. I mentioned a number of companies that make similar products, but there is too large of a barrier for entry for an average person to use it. The Pi and Arduino break down existing barriers to entry much like Apple did to revolutionize the computer, and mp3 player.My vision has long been in incorporating a GUI, a strong processor compared to typical microcontrollers, easy to use and robust digital and analog I/O into one product, and most importantly open to allow people full access to all features. The Pi has the first two. The Arduino has the last one for sure and with a good shield, the third one as well. I really want all of the above in one product.

content: Well, I can add this: When I had one of my packages listed on ebay as for the Arduino it was very popular and usually I sell every one I list. Reading this thread reminded me of the Raspberry pi and so I added that to the title. It seems the number of views of those listings increased ramatically (double those listings without) but it doesn't seem to make them sell any better.Arduino users buy damn near everything listed for them on ebay. Raspberry users (os should I say potential) seem to be more interested in actually getting one of the damn things at a reasonable price. And fifty pounds for a 35 dollar device is not reasonable.

content: Pi is for coders who want a cheap machine to mess with software linux.Arduino is for people who want to control things ( motors etc )there is one problem with pi that has not been addressed yet .. the broadcomm chip used.that thing is an Soc for embeeded purposes. these things have a limited life-cycle. much shorter than a general purpose cpu like the 328.. that thing will still be in production 10 years from now. the broadcomm ? give it another year and it is end of life ... broadcomm made that chip with a specific customer in mind ( no, not the Pi ) . the reason Pi is delay is because they hit the jackpot at broadcomm. someone is buying bulk orders of that chip for a commercial prouct, a router , a hotspot, maybe a cellphone... when that commercial contract ceases to exist and there is no 'bulk' customer they will pull the plug on production. this chip is not a general purpose device but an SoC with an intended market. if that market moves on it will cease to exist. the Pi is piggybacking and already in trouble. The real target audience of the chip is gobbling them up faster than broadcomm can make then so Pi can't get the chips. That 'real' product has begun its lifespan. and we all know that commercial products have a max 1 to 2 year span before they are replaced by a new generation... so the broadcomm chip will disappear by the end of next year.... lights out for pi as they can't get a hold of the core component..It is a VERY bad idea to design a platform by riding along on an SoC if you are not the target audience and cannot pull the volume required to keep the thing alive.

content: all he claims is they have production capability for 10000 pi's a day .. but they can;t get the chips from broadcomm..The reason behind that is simply that broadcomm has a contract with some extreme volume buyer for this chip and they tell anyone else to sod-off.10000 chips of one product a day is nothing. let's say a company like nokia or cisco ( linksys ) steps in and says : we have a product. we are going to buy 50 or 100k a day, then the poor sod who want 10k a day will simply have to wait until they can ramp up production , which is taking 2 months. All the fabs are filled to capacity and a slot will only be made available for continuous supply. Not for a one-time stint. that is simply how semcionductor business works for this kind of product.Second factor is that big boys will have signed contracts for x chips a day over a period of x months. with penalties if delivery falls short. Try to get in there and you will be shown the door.The Pi foundation was blindsighted by the success. they got waay more orders than they could handle. they sucked distribution dry and now there's not a single chip tp be had anywhere. even the distributors can't get their hands on them.I know of situations where it is simply impossible to get a part unless you have a idrect manufacturer contract. There is a stupid shottky diode ( murs520 i believe ) which in 2009 all of a sudden became very popular. every adsl modem produced has 4 of these for line protection. this diode has such low capacitance it has no impact on the line signal. Well , if you needed that diode because you had it in a design the projected wait time was 150 weeks. that's 3 years ! good luck if that sits in a power supply you just designed. you can flush the design down the drain ( it had a weird package that noone else had at the time ) fortunately some other companies stepped in and produced alternatives that worked fine and the wait time was reduced to 20 weeks. but that;s still half a year. you order a reel of 5000 or even 10 reels of 5000 and they bluntly tell you : 6 months from now. not earlier. sorry.this is exactly the hole that the Pi is in right now. It caught on with its targeted audience and the 'litle guy' can't get parts. and when the targeted audience moves on to the next 'high runner' broadcomm will have no qualms about killing that part off. Let's say the Pi foundation want to buy a total volume of 2 million of these chips... broadcomm would be losing money on it. they lock a fab slot that could be used for a chip in much higher volume and with a longer forecast and more revenue. they'd be stupid to keep producing it. Besides , that chip also costs them money. broadcomm does't own waferfabs. they use foundries like TSMC and UMC in taiwan.That pictures changes if they would have their own fabs. then you could use these products as fab filler.Here's the thing with a waferfab:you have a fixed annual operating cost : personell , gases , chemicals, airconditioning, equipment maintencance. even if you do not produce a single wafer that cost remains the same ( you cannot have semiconductor equipment sit idle. it throws off the processes. when a machine has nothing to do for more than 3 hours they begin cycling 'dummy wafers'. For example : the plasma reactor is being coated with byproducts during processing. as long as you keep aplying a fresh coat of 'gunk' nothing happens. stop the machine for a few hours and this gunk starts drying out , becomes flakes and falls down. run a wafer then and you have only scrap material. the reactor needs maintenance . maintenance to clean the reactor ona typical alu etcher takes about 4 to 6 hours. maintencae is required after 1500 wafers anyway. let's say you just had the reactor cleaned , ran 300 wafers and it now sits idle for 3 hours... we are going to start running dummies. just a blank wafer with alu on it : etch it off so we prevent the flakes from forming. we cycle dummies at a rate of a lot ( 25 wafers ) every few hours. this extends the cleaning interval. when real work comes along the machine is available.so , all that stuff is 'fixed cost' Now , what is a 'fab filler' ? those are the products that , when run through the fab , pay for the baseline cost of the fab ( personell consumables , equipment maintenance. when you run these roducts your fab becomes a net zero operation. you don;t make any money but you don't lose any either. a typical waferfab uses about 50% of its capacity in 'fillers' to break even. anything else you shove in there becomes pure profit ( minus the cost of the blank wafer and not accounting for scrap ). So, in that case you could affort to keep runing the 'low volume' Pi' chip. it would become a fab filler. it doesn't make any money in itself but it allows other products to bring in money. no fillers = no fab as the oter products would only give you break even.Only foundries do not use this model. these have so maney different high-run projects that they don't want 'fillers' they don't need them. they want 3 or 4 high-runners and that runs the fab. So designing with a part that is run as high flyer in a foundry is dangerous. if the part is demoted from high flyer to low demand it will simlpy be killed. the foundries don't want those and there is no incentive for the part 'owner' to keep produceing them they will use that slot to run some other high flyer.semiconductor manufacturing is a complex world. i would never design a low volume product using a device target for high volume production run by a foundry. simply becasue delivery will be uncertain becasue a big boy may absorb all capacity, and when the big boy doesn't need it anymore the product will cease production altogether... waaay too dangerous.

content: When I was just starting as an engineer one of the first products I helped design was a wire harness tester. It was novel enough in concept it was patented, and rather than muxes it used devices to short test pins. The box could handle up to 512 points, and two could be slaved to control 1024 points. Each group of 8 pins used one UCN4801, a Sprague part. When the order came in from General Motors for 1000 units, we were suddenly faced with having to buy 128,000 of these 4801s. Guess what happened?Sprague, being privately held and able to do as Mr Sprague damn well pleased, saw this increased demand and stopped production of the 4801, allowing all the 4801s in the supply chain to be bought up by us. The price of our product increased so quickly and so high that we redesigned the boards to use 4401s, which are half a 4801. So now we needed a quarter Million of the things...It'snevera good idea to design in a single source part.

There is no chance that anyone alse is allowed to make a pin for pin compatible fuctional clone. so you are stuck to this one part form one vendor...These devices have a target audience. home computers boards for hobbyists is NOT that audience... neither is 'open market' (meaning anyone can buy these and delivery is guaranteed long term.). very dangerous to design something with such a device unless you can deal with the manufacturer directly. and 1 million parts over a few years these days doesn't get you an audience... not when they have products that run in the 500.000 to 1 million a day .. with backing contracts for 2 or 3 years supply.

We were actually looking seriously at getting a custom chip done for the project I just mentioned and it was almost affordable at our expected quantities even in 1983.If you're going to design a chip, whether or not it is "pin compatible" (which is irrelevant since pinouts cannot be patented) is also irrelevant because designing a pc board is trivial compared to getting a chip done.I would bet, if they had known they would get this sort of response, they could have struck a good deal with intel. Too bad they didn't. Even if it cost 45 bucks instead of 35, at least we'd have them by now and the design would be far more open.

The Zynq board is just for the initial prototyping. I'm guessing the new Kickstarter rules that disallow showing pictures or renderings of anything that is not actually done at the time of the campaign are making it a bit dificult to get that point across.Or maybe the whole kickstarter campaign is some final desperate grab for money from an almost bankrupt company or something similar...The point of using a parallel core design instead of an FPGA, according to them anyways, seems to be the low power consumption and being able to code in C and OpenCL instead of using VHDL/Verilog. As someone who considers himself to be quite proficient in C and is currently frustrated with trying to get something useful done with a Terasic DE1 FPGA dev board, I can see where they are coming from.I found the whole idea fascinating to be honest. Not really ready to give them any of my money just yet though...

This makes me wonder - they already have photos of some chips, which also look like generic coprocessors. So what is the point of the project? Collect money to design a board from already available ARM chip and already available coprocessor chip? $750,000 is way more than it really costs. If they want to produce some silicon, I'd like to know what exactly will be produced.Quote from: Tuomas on October 17, 2012, 10:08:41 pmThat seems to be a goal. They want money to make another spin of their silicon, and from this spin produce few boards (of questionable value to the customer) and sell the rest at a market price or use as a promotion.Quote from: Tuomas on October 17, 2012, 10:08:41 pmCreating programs for multicore systems is actually more challenging than developing for FPGA.

Not only are you attaching a programmable device to a ridiculously closed and hard to get architecture, you'd actually have to BIT BANG the damn fpga program because... guess what? There isn't even an open way to access the damn SPI interface.It's only been six months now. I can't wait for my pi to get here so I can dump the damn thing on ebay. By the time I get it it will probably be worth less than I paid for it. Fucka Buncha pi.

If you think Android isn't partially closed, you are sadly deluded.QuoteThe Linux kernel for Raspberry Pi has supported SPI as a native device for months. Get your facts straight.QuoteWow, someone widdled in your wheaties this morning, didn't they?The Raspberry Pi is as open as the Foundation can make it, and they are working hard to open it further. It's a charity, for Pete's sake, not some evil megacorporation.

content: IMO it would nice to use RasPi as an interface to several Arduinos, and let the Arduino handle the electronics and the RasPi acting as a hub and UI.I.e. with wireless modules connected to SPI.It's two complete different systems, but they can be used to build lager more complex system.My 2 cent.

content: Broadcom published open source video drivers for the SoC used in RPihttp://www.raspberrypi.org/archives/2221.PS: Now who would bet that this move from Broadcoam is based on the success of the RPi? If it is so, then they achieved very important goal already.PPS: Mine arrives tomorrow
