This is really cool. I am very impressed by all of these projects. It's wonderful to see that people are doing such innovative and creative things with Raspberry Pi. I especially love the retro phones stereo control, the Atari emulator and, of course, the R2D2 (who doesn't?)
Some nice little tutorials on these pages. The word is books are being written as teaching material on the Raspberry Pi as platform for a variety of subjects, so hopefully we're poised to see it take off in computer science classes.
Yup, noticed that after I went back to reread the thread. Further investigation does indeed reveal existing dedicated Bitcoin mining hardware that can far outperform the Parallella, at least in this application. And there are now even USB Bitcoin miners, as noted in the Raspberry Pi tutorial mentioned, which shows how to use the Pi as a headless controller and monitor for these devices. Very interesting.
I have had several professors tell me they refuse to use RPi because Broadcom will not release a DS for the MCU. Does this bother anyone else? RPi is losing potential adopters to Beagle Bone because of this.
RasPi does have a Broadcom ARM Peripherals data sheet that documents BCM2835 GPIOs and serial peripherals connected to RasPi's expansion header. This is enough for most users. The full data sheet is not available, but since you can't buy the BCM2835 in small quantities it wouldn't be that helpful anyway. Some people are upset about this, but it is what it is and there are plenty of alternate boards available, like BeagleBone.
BeagleBone and RasPi address different markets. BeagleBone is targetted at EEs who need lots of I/O pins and serial peripherals, or people who need an integrated Ethernet controller for performance and/or a USB host that's better behaved. RasPi has better video processing, so it's preferable as a media center. The price difference between RasPi Model B (plus an SD card) and BeagleBone Black is minimal.
I suspect it is limited. Any time you move to quantity, you end up designing a specific system for your need. It is more cost effective. I can't imagine multi thousand scale runs of a product with the Raspberry Pi crammed inside.
@selinz See my comment in this thread. I emailed Judd, and he replied that the system isn't working. Maybe the barrage of emails was so massive that the owner had to shut it off temporarily, for Judd to recover.
Thanks for sharing these cool projects. Coming off of our hugely popular Raspberry Pi hands on workshops at DESIGN West 2014, we're already organizing our sessions for next year. These projects inspire me to think outside of the box on what we can provide for attendees to build.
I emailed Judd the dog today, who was featured in Slide 9of this slideshow - a device his owner built that gives the dog a treat everytime someone emails the dog. This is the text in the email I received from Judd, and photo:
"Terrible News! The USB webcam is not working reliably anymore. I am going to ask my owner to upgrade to the new Raspberry Pi Camera! Woof Woof! Maybe the attached photo will convince him? "
@kfield, Awww. Poor dog. Pavlov would be proud. I wonder if we're the subjects of this Pavlovian experiment, though. Speaking of, NobelPrize.org has a Pavlov's dog video game to play while you wait for the Judd's owner to upgrade his webcam.
This is cute on its surface. But I love dogs and -- not to sound like an extremist -- I think it is, perhaps, a bit cruel to tie treats to emails. First, if he gets none, the dog would feel punished for no reason. Second, if he gets too many, the dog would grow obese because dogs instinctively eat and eat when food is available.
However, I have a modest proposal to offer as alternative: perhaps the clever inventor would want to tie his own diet to the delivery of emails? No emails, no dinner.
Not to end on a total downnote, I'll share a story about my pup. Our neighbors in the redwood forest include a family of ravens. Ravens and dogs have a relationship going back tens of thousands of years, and dogs can understand ravens when they talk (Ravens have about 30 "words," ranging from "hungry" to "danger" to "dinner time.") I've come to recognize some of the sounds myself, which is helpful for avoiding coyotes or other predators.
In a movie on a DVD last night, a sound effect had ravens making their "Danger!" call, and my dog promptly ran out of the house and began barking to warn others. He settled down only after we convinced him it was only a movie.
i would like to invite you and your owner to present at DESIGN West 2014 in San Jose March 31-April 3. Our attendees would love a talk on using Python to program the Raspberry Pi and the snack feature would be a great demo. K
