Raspberry Pi: computing for pocket change -- $5 computer unleashes a storm of creative computing
CBC News ^ | 01/04/2016 | By Greg Rasmussen, CBC News

Posted on 01/04/2016 12:36:43 PM PST by SeekAndFind

The era of the $5 computer has arrived.

The latest version of the Raspberry Pi is even being given away free with a magazine. Not a subscription. Just buy the single issue of Magpi and you get a free computer.

The devices have hobbyists and entrepreneurs excited about the possibilities of Pi.

Ben Z. Cooper is using one as the brains behind a spectacular light show at Vancouver's VanDusen Gardens.

"You wave your hand in the air and control a whole grove of maple trees lighting up," Cooper told CBC News as he displayed his invention.

A partner in Hfour design studio, he used a customized version of the Pi to interpret signals from infrared sensors and send them to a series of powerful spotlights beneath individual trees.

It's called the Light Wave and users simply move their hands over a series of sensors to trigger different lights, similar to conducting a symphony of lights.

Cooper is a big fan of cheap computers.

"It's just incredible. what we're using today in the Light Wave would have cost us 10 times as much 10 years ago. It lets us put a little computer inside of an object and just leave it there."

Behind it all is the Raspberry Foundation, a U.K. charity dedicated to computer education and cheap technology. The latest Raspberry Pi, called the Zero, is part of a movement that combines inexpensive hardware, collaboration and open source software to drive prices down and create an explosion of new uses for computers.

One place keen on the ultra cheap computers is Hackspace, a place where hobbyists meet to swap ideas and work on technology projects in Vancouver.

Hackspace director Rob MacKenzie has one of the devices hooked up to a monitor and keyboard to show that, at its heart, the Pi can handle word processing and web browsing like far more expensive computers.

Nearby, inside a vending machine alongside Snickers bars and other junk food, is a row of cheap computer parts including earlier versions of the Raspberry Pi.

"I'm definitely waiting to get my hands on some of the $5 ones. They're really hard to get right now. They've been sold out everywhere I can see, but they're pumping them out as fast as they can."

Hackspace member Jon Grieman is using a Pi as the brains behind a futuristic pinball machine he's designing.

He says it brings powerful computing down to mere pocket change.

"It's a cup of coffee. I can have a couple sitting in a box and when I need one pull it out and leave it in a project."

Another project looks like an old time wooden camera, but is, in fact, a very modern automated selfie machine on steroids capable of instantly posting pictures to a big screen or direct to the internet.

Builder Luke Cyca welcomes the new, cheaper computers.

"In terms of price it's wonderful, I wouldn't be able to justify buying a computer to dedicate to this project which I've used only a handful of times."

And looking online at what people are doing with the little devices it's clearly a wide, sometimes weird, life of Pi.

“Why?”

35 years ago I used a home computer that cost $100 in kit form. 1KB RAM. Audio cassette data storage. Home TV for a screen.
Now for $5 you can get a Raspberry Pi Zero, operating capabilities in the vicinity of the Cray 2 & iPad 2, using your home TV for a screen (and whatever stray keyboard & mouse & SD card you can find lying around unused).
100x faster.
2700x more pixels.
1,000,000x more memory.
1/20th the price.
That’s cool.

Any idea where to pick up the copy of Magpi?

Sounds like the mighty Sinclair ZX-81!

Loved that little Z80 beast!

Why is the thread only for “techies”? I’m no “techie” and I find the subject fascinating. I can see all kinds of uses for this stuff- especially for SHTF times.

link: $30 from adafruit.com

follow-up:

this would be the camera. it will support 720p60 ... more then enough for vision.

so... $35 per 'eye'. then i'd add a third board for 'the brain'


link: $50 from intel (performance comparison: link)

combined, it would be pretty small, have binocular vision, and be able to control other on-board devices easily

I just got my first PI 2 for Christmas. I have it set up as a LAMP server (Linux, Apache, MySQL and PHP). It collects data from temperature and humidity sensors (driven by Arduino) in the attic and crawlspace. This replaces a Virtual Machine I had running on my Windows 10 box.

Can’t wait to get my hands on the $5 version.

ZX-80, actually. Programmed that thing to the limits, which were extremely narrow. Learned a lot trying to cram program, OS, and video into just 1024 bytes. Even built a sound card for it, playing music the very hard way.

Then you’re a techie (broadly defined for friendly purposes).

RE: Can I get some Java with the Raspberry Pi?

Absolutely.

See here:

http://www.drdobbs.com/jvm/java-apps-on-the-raspberry-pi/240155309

TITLE: Java Apps on the Raspberry Pi

There is in fact, an Open Source project to provide a friendly object-oriented I/O API and implementation libraries for Java Programmers to access the full I/O capabilities of the Raspberry Pi platform. This project abstracts the low-level native integration and interrupt monitoring to enable Java programmers to focus on implementing their application business logic.

Yeah I am going to have to pick myself up a couple of them to tinker around with . My husband is so going to kill me because I just cleaned up the closet I keep my computer parts in . I can hear it now .... Do you really need more junk ? lol

Those were fun times! Loved Sinclair BASIC, and moved on to assembly language. I built my ZX81 & 16K ram expansion into an old cable converter box along with a keyboard to create a self-contained computer. With that Z80 I/O bus hanging out the back, it was a ball wire-wrapping little projects on perfboard, then writing the programs to run 'em.

That was actually my THIRD home computer, following COSMAC Elf in 1976 and a KIM-1 a couple of years later.

Sold the KIM on eBay for over $2k a couple of years ago. Although I've divested myself of a lot of other personal computer stuff in recent years, I certainly lucked out in picking the one that I thought might be worth a little $ someday!

Why?

I have a need for it. Currently, I have two 3D printers. I have to connect my Mac in order to not only create what I want to print, but to control the 3D printer. I can connect a SD card to the 3D printer to print from a stored object already created, but I find that problematic if anything goes wrong. The Raspberry Pi would allow me to cheaply dedicate a computer to each printer for all print tasks. If you use 3D printers, you would know they take hours to complete a print job. This would free up my regular computers for other use.

I personally liked Beaglebone Black, but it's too expensive. Costs nothing compared to servo motors of course.
