I'm interested in Raspberry Pi. I bought one before. It's just a small PC, use one hand you can hold it. But when you want to Raspberry to do some complex works, it let you down. I want to know where does Raspberry Pi can work well?
Oh man, I was really hoping for a better CPU. The current one is just so dang slow.
Have them fixed the broken USB system? (USB and Ethernet share the same bus problem)
What's the same: - Same Broadcom BCM2835 Chipset - Same 512MB RAM - Same full size HDMI port - Same 10/100 Ethernet port - Same CSI camera port and DSI display ports - Same micro USB power supply connection What has changed: - Now comes with 4 USB ports so you can now connect more devices than ever to your Raspberry Pi. - There is a 40pin extended GPIO so you can build even bigger and better projects than ever before…
Right now it's possible to back feed power with a powered hub instead of using the micro USB connection. I'd like to see the schematic to find out if that's still possible, but I can't find one yet.

Slow and proprietary, which is not a great combination... there's a lot of interesting new ARM SoCs from China that are coming out, like the Allwinner A3x series (quad A7s, >1GHz). It would be pretty unlikely for one of those to show up in the next Pi though; if anything, it'll probably be another Broadcom.
I still can't see why would anyone buy one except as one of those toys that you buy and then gets tossed in the closet. 10 years ago I could see the appeal, but now? The robotics, home automation, and weekend project use cases seem like would be better served by a $5 microcontroller. Some projects, such as the weather station, justify the use of a full-fledged OS, but with the cost of buying an existing, proven, weat…
My colleague uses it to run a python script to periodically download and store virtual currency prices. As I understand it, it is useful if you want to download stuff from the internet in certain time intervals.
I still like the Pi, though. There are some people for whom saving $30 really does make a big difference, and if the goal is learning how computers work, having lots of GPIO pins, etc, the Pi is still awesome.

I built my own home security system with a Pi as the brains to control camera streaming and do face recognition using OpenCV. Is there a $5 microcontroller that can do all that? Admittedly, it's a big load on the Pi and I'm looking for more powerful single board computers, but that again eliminates $5 MCUs. I have another Pi working as a drop-in replacement wifi router that routes data via a USB data dongle in case m…

I don't have the Raspberry Pi, mainly because, since I develop embedded software for a living, I have an endless supply of development boards I can hack on at work and am free to take home (during those evenings when I am not so fucking tired of flipping bits that I don't even want to SEE C code!), but : * A platform with less legacy crap than x86 is wonderful for learning about OS development. I don't know how the P…
> A platform with less legacy crap than x86 is wonderful for learning about OS development. I don't know how the Pi fares for this, with Broadcom's chip and all, but if I had the free time to hack an OS in my spare time, not dealing with all the thirty year-old cruft nor shedding a gazillion EUR on a PowerPC system would be ideal. Actually I'd say the x86/PC is probably one of the best-documented and most stable plat…
Unfortunately, that also means there's a lot of inconsistency, conflicting advice and outdated code that beginners take for granted. It's quite annoying.

That sounds awesome! Would you mind sharing your project?
