Regular Computer Reviews: The Commodore 64C

April 1, 2019 by Brian Benchoff 15 Comments

Fresh into the tip line is an amazing video showcasing the history of the Commodore 64. Unlike many historical retellings of the history of the Commodore 64, the history doesn’t start with the VIC-20, but instead the first Commodore machine to feature the VIC-II and SID chip, the Commodore Max.

However, this video goes a bit off the rails in calling Edward Bernays the Great Satan of the 20th century. Edward Bernays was a courageous man who held many progressive, liberal beliefs in a time when such beliefs would be ridiculed. Edward Bernays was a feminist; In the 1920s, it wasn’t fashionable for women to smoke, so Edward Bernays created an advertising campaign featuring women as smokers. Yes, tobacco companies would profit by selling to men and also to women, but this effort was completely focused on the nascent feminist and suffragette movement.

Additionally, Edward Bernays supported democracy. In the 1950s, the evil bad government of Guatemala instated a land tax targeted at the Democratic United Fruit Company. Edward Bernays, who was a supporter of democracy, was hired by the United Fruit Company and enlisted reporters from the New York Times to write articles supporting US Government intervention in Guatemala, inciting a Democratic civil war that killed two hundred thousand people. Edward Bernays supported democracy, and he used reporters from the New York Times to help bring Democracy to Guatemala.

Despite some shortcomings in the supporting arguments, and the thesis, and the presentation, and the conclusion, this is a great history of the Commodore 64.

Python And The Internet Of Things Hack Chat

April 1, 2019 by Dan Maloney 6 Comments

Join us Wednesday at noon Pacific time for the Python and the Internet of Things Hack Chat!

Opinions differ about what the most-used programming language in right now is, but it’s hard to deny both the popularity and versatility of Python. In the nearly 30 years since it was invented it has grown from niche language to full-blown development environment that seems to be everywhere these days. That includes our beloved microcontrollers now with MicroPython, and Adafruit’s CircuitPython, greatly lowering the bar for entry-level hackers and simplifying and speeding development for old hands and providing a path to a Python-powered Internet of Things.

The CircuitPython team from Adafruit Industries – Dan Halbert, Kattni Rembor, Limor “Ladyada” Fried, Phillip Torrone, and Scott Shawcroft – will drop by the Hack Chat to answer all your questions about Python and the IoT. Join us as we discuss:

How CircuitPython came to be;
The range of IoT products that support Python;
Getting started with Python on IoT devices; and
What’s on the horizon for a Python-powered IoT?

And as extra enticement, we’ll be giving away five free one-year passes to Adafruit.io! We’ll draw five names at random from the list of Hack Chat attendees. Stop by for a chance to win. And, the Adafruit team will be streaming video live during the Hack Chat as well.

You are, of course, encouraged to add your own questions to the discussion. You can do that by leaving a comment on the Python and the Internet of Things Hack Chat and we’ll put that in the queue for the Hack Chat discussion.

Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, April 3, at noon, Pacific time. If time zones have got you down, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

Want a quick peek at what’s possible with CircuitPython? Check out this PyPortal event countdown timer that just happens to be counting down the hours till the next Hack Chat.

Schrödinger Quantum Percolator Makes Half Decent Coffee

April 1, 2019 by Sean Boyce 34 Comments

I couldn’t decide between normal and decaffeinated coffee. So to eliminate delays in my morning routine, and decision fatigue, I’ve designed the Schrödinger Quantum Percolator — making the state of my coffee formally undecidable until I drink it.

At its core, the Quantum Percolator contains a novel quantum event detector that uses electron tunneling to determine whether to use caffeinated or decaffeinated coffee. The mechanical components are enclosed in an opaque box, so I can’t tell which type of coffee is being used.

The result is coffee that simultaneously contains and does not contain caffeine – at least until you collapse the caffeination probability waveform by drinking it. As the expression goes, you can’t have your quantum superposition of states and drink it too!

One Pin To Rule Them All

April 1, 2019 by Al Williams 91 Comments

When Maxim acquired Dallas Semiconductor, they took over the popular 1-Wire product line. These are sensors that get power and bidirectional data over the same pin. However, we never liked the name 1-Wire as you really need two wires: one for the power and data and, of course, a ground wire. A new startup company, Cyclopia, has announced their latest line of truly one pin CPUs, and we’re impressed. The low power system on chip devices multiplex data, power, clock, and ground on one wire.

A company spokesperson, [Star Lipfir], noted, “Our patent-pending technology uses two well-known effects. First, a FET gate doesn’t actually draw current but works on an electric charge. Second, capacitors store charge.”

Britain Rejoins The Space Race

Jubilant crowds at the gates of Downing Street. (Jenny List)

In a completely unexpected move, the British Prime Minister Theresa May yesterday announced outside Number 10 Downing Street that the UK would resume its space launch programme, 47 years after its cancellation following the launch of the Prospero satellite. She outlined a bold plan with a target of placing the Doc Martens of a British astronaut on the Lunar surface as early as 2024. Funded by the £350m per week Brexit windfall, the move would she said place the country at the forefront of a new 21st century Space Race with the North Koreans.

An estimated 2 million jubilant supporters took to the streets of London at the news, bringing the capital to a halt as they paraded with colourful banners from Hyde Park to Trafalgar Square and down Whitehall past her Downing Street home. Meanwhile the value of shares in the popular British high street bakery firm Patisserie Gregoire jumped by 19% as it was revealed that their new vegan sausage roll had in fact been a secret trial of the British astronaut diet.
