Arduino, Raspberry PI, and Beaglebone Black

[Savoirfaire]

Arduino operates in a different realm than the latter two.

You can use these chips to build Software Defined Radios (SDR).

There have been one or more forums on the website about SDR radios.

Has anyone built a Raspberry Pi project? The project ideas I've seen written about are not very practical. I would get one just for the hands-on experience but I really need to have some useful purpose in mind to justify it.

Arduino is the most popular, you can find a project book at the local library, the other too are way too complicated and expensive.

I've played with arduino's and raspberry pi's. I have a raspberry pi running as a web server atm, it is what hosts all of the pictures I use for forums... If thinking of getting a raspberry pi you might want to wait a bit, apparently there are rumors of a raspberry pi 3 being developed, with certain certifications for wireless and bluetooth having been submitted to the FCC, and thus a matter of public record.

Actually just noticed that the Raspberry Pi 3 is on sale now for the same price as the 2...

Did you configure it from project plans/specs that are published on the www? If yes, would you please share the link?

Apparently, each has strengths/weaknesses for specific uses. I read that Arduino is better suited as a hardware device controller.

I used to play with linux years ago so I'm somewhat used to it. I actually got the device as part of a class, it was required for schoolwork. After class was over I reloaded the unit and set up SSH with the initial setup, then connected remotely and used the built in help files to set up a static IP and Apache. I also set up samba, so I can literally drag and drop the files onto the server from my windows computer and they are there instantly. The only wires plugged into it are power and ethernet, and the GUI was never told to load.

I'm sure there are web sites that have directions for the various parts of setting such a server up, and I'm sure there are 10 videos of eight year old kids on youtube explaining the process, but given time to play around with it I can figure it out without such aids. I prefer this method, if only because that is how I used to have to do everything in the pre-internet days...

You're quite correct, there is a wealth of project ideas all documented on various websites.

After reviewing most of them, I've come to the conclusion there is nothing remotely practical to assemble. Virtually everything you might build is already available in a more finished commercial product at a comparable or lower price. I appreciate the value of hands-on tinkering and learning but I also wanted to do something that made sense.

I'll keep an eye on new project ideas as this product evolves.

I get a magazine in the mail, (lifetime subscription), years ago they were heavily into radio, next was computers, then robotics, now getting back into a little of everything again, it's called "Nuts and Volts", they have been doing some articles on all three of these controllers.

I'll check it out, I just took a quick look and they have an extensive website.

One of the big difference in electronics now versus a couple decades ago is the low cost of products resulting from Asian manufacturing. Back in the day, there was some advantage to DIY projects ... remember Heathkit? These days you can buy a multimeter for less than the cost of the battery it uses. And if you are willing to wait a few weeks for delivery, you can buy electronics products on eBay from sellers in China for so cheap it doesn't make sense to build anything anymore.

Remember Heathkit?, I worked at the local store when I was a kid, along with Lafayette and Allied Radio (Shack).

I purchased my shortwave receiver at the Heathkit store in Long Island, circa 1974. Same place my neighbor purchased and assembled one of the first TV sets which displayed the channel # on the screen, causing our jaws to drop the first time we saw it.

Thanks for making me aware of NutsVolts magazine. I'm not a subscriber, but because you made me aware of it I check the magazine stand every time I visit my local bookstore and enjoy scanning it. Most of the projects it describes are beyond my skill level, but I enjoy looking at the ads which have a very vintage feel to them. Takes me back to Popular Electronics mags of the 70's with all the analog components for sale. Those were the days.
