The Joy Of Broadcast Media Vs. The Paradox Of Choice

The rise of streaming services on the Internet was a revolutionary shift when it came to the world of media. No more would content be pumped in to homes in a one-way fashion, broadcast by major conglomerates and government-run organizations. Instead, individuals would be free to hunt for content suiting their own desires on an all-you-can-watch basis.

It’s led to a paradigm shift in the way we consume media. However, it’s also led to immense frustration thanks to the overwhelming amount of content on offer.  Let’s take a look at why that is, and some creative ways you can get around the problem.

The Paradox of Choice

Many find the masses of content on streaming services to be overwhelming to choose from. Credit: author screenshot

Traditionally, when it came to media, there were two major arms of delivery: broadcast, and home media. One might listen to the radio, or flick on the TV, or alternatively, spin up a record, or select a movie to watch on tape. If none of those options  sufficed, one might take a walk down to the local video store to rent something more appealing.

Fundamentally, it was an era in which choices were limited. There were a handful of TV stations to choose from, and if nothing good was on, you could go as far as finding something watchable on tape or going without. Many will remember afternoons and evenings spent watching reruns or a Friday night movie that had been on a million times before. Some shows went as far as becoming legends for their seemingly endless replay, from The Simpsons to M*A*S*H. 

As the Internet grew, though, the game started to change. Torrent websites and streaming services came along, offering up the sum total of the world’s cultural output for free, or for a nominal cost for those averse to piracy. Suddenly when it came to choosing a movie to watch, one wasn’t limited to the five or so films on at the local cinema, nor what was left on the shelves at the local video rental. Instead, virtually any movie, from the invention of the format, could be yours to watch at a moment’s notice.

With so many options on the table, many of us find it harder to choose. It’s an idea popularly known as the Paradox of Choice, a term popularized by US psychologist Barry Schwartz in 2004. When our options are limited to a select few, choice is easy. They can quickly be compared and ranked and an ideal option chosen.

Add thousands of choices to the pile, and the job escalates in complexity to the point of becoming overwhelming. With so many different choices to contrast and compare, finding the mythical right choice becomes practically impossible. Continue reading “The Joy Of Broadcast Media Vs. The Paradox Of Choice”

Handling Bulk Material: Why Does My Cat Food Get Stuck?

Bulk material is stuff handled ‘in bulk’. One LEGO piece is a brick but 1,000 poured into a bag is bulk material. Corn starch, sand, flour, powder-coat powder, gravel, cat food, Cap’n Crunch, coins, screws, Styrofoam beads, lead shot, and gummy worms are bulk materials.

Applications abound where you need to move stuff in bulk. Selective sintering 3D printers, animal feeders, DIY injection molders, toner based PCB makers, home powder coating, automatic LEGO/domino/whatever sorters or assemblers, automated gardeners, airsoft accessories – handling bulk material is part of hacking. College science classes cover solids and liquids, but rarely bulk materials.

Most hackers just pray it works and tap the bin when it doesn’t. Industry does better, but the slang term “bin rash”, the long term result of tapping a 300 ton bin with sledgehammers (video),  shows they don’t get it right all the time either. At the same time, it’s a fun area you can experiment with using kitchen items. So come along with us for a short series on the basics of bulk material handling.

Natural Language AI In Your Next Project? It’s Easier Than You Think

Want your next project to trash talk? Dynamically rewrite boring log messages as sci-fi technobabble? Happily (or grudgingly) answer questions? Doing that sort of thing and more can be done with OpenAI’s GPT-3, a natural language prediction model with an API that is probably a lot easier to use than you might think.

In fact, if you have basic Python coding skills, or even just the ability to craft a curl statement, you have just about everything you need to add this ability to your next project. It’s not free in the long run, although initial use is free on signup, but for personal projects the costs will be very small.

Basic Concepts

OpenAI has an API that provides access to GPT-3, a machine learning model with the ability to perform just about any task that involves understanding or generating natural-sounding language.

OpenAI provides some excellent documentation as well as a web tool through which one can experiment interactively. First, however, one must create an account and receive an API key. After that is done, the doors are open.

Creating an account also gives one a number of free credits that can be used to experiment with ideas. Once the free trial is used up or expires, using the API will cost money. How much? Not a lot, frankly. Everything sent to (and received from) the API is broken into tokens, and pricing is from $0.0008 to $0.06 per thousand tokens. A thousand tokens is roughly 750 words, so small projects are really not a big financial commitment. My free trial came with 18 USD of credits, of which I have so far barely managed to spend 5%.

Let’s take a closer look at how it works, and what can be done with it!

Silence Of The IPods: Reflecting On The Ever-Shifting Landscape Of Personal Media Consumption

On October 23rd of 2001, the first Apple iPod was launched. It wasn’t the first Personal Media Player (PMP), but as with many things Apple the iPod would go on to provide the benchmark for what a PMP should do, as well as what they should look like. While few today remember the PMP trailblazers like Diamond’s Rio devices, it’s hard to find anyone who doesn’t know what an ‘iPod’ is.

Even as Microsoft, Sony and others tried to steal the PMP crown, the iPod remained the irrefutable market leader, all the while gaining more and more features such as video playback and a touch display. Yet despite this success, in 2017 Apple discontinued its audio-only iPods (Nano and Shuffle), and as of May 10th, 2022, the Apple iPod Touch was discontinued. This marks the end of Apple’s foray into the PMP market, and makes one wonder whether the PMP market of the late 90s is gone, or maybe just has transformed into something else.

After all, with everyone and their pet hamster having a smartphone nowadays, what need is there for a portable device that can ‘only’ play back audio and perhaps video?

Will We Ever Shake The Polaroid Picture?

Today, most of us carry supercomputers in our pockets that happen to also take instantly-viewable pictures.This is something that even the dumbest phones do, meaning that we can reasonably draw the conclusion that photographic capability has become a basic feature of everyday carry, a necessity of 21st century life.

Despite the unwashed masses of just-plain-bad photographs clouding the digital landscape, photography itself remains as important as ever so we can retain and disseminate information as history unfolds. In a sense, the more instant, the better — unless it comes at the cost of image quality. The invention of photography is on par with the printing press or with language itself in that all three allow us to communicate within our own time as well as preserve The Way Things Were in frozen silence. And no invention made vivid preservation more convenient than the instant camera.

The Connector Zoo: I2C Ecosystems

I2C is a wonderful interface. With four wires and only two GPIOs, you can connect a whole lot of sensors and devices – in parallel, at that! You will see I2C used basically everywhere, in every phone, laptop, desktop, and any device with more than a few ICs inside of it – and most microcontrollers have I2C support baked into their hardware. As a result, there’s a myriad of interesting and useful devices you can use I2C with. Occasionally, maker-facing companies create plug-and-play interfaces for the I2C device breakouts they produce, with standardized pinouts and connectors.

Following a standard pinout is way better than inventing your own, and your experience with inconsistent pin header pinouts on generic I2C modules from China will surely reflect that. Wouldn’t it be wonderful if you could just plug a single I2C-carrying connector into an MPU9050, MLX90614 or HMC5883L breakout you bought for a few dollars, as opposed to the usual hurdle of looking at the module’s silkscreen, soldering pin headers onto it and carefully arranging female headers onto the correct pins?

As with any standard, when it comes to I2C-on-a-connector conventions, you would correctly guess that there’s more than one, and they all have their pros and cons. There aren’t quite fifteen, but there’s definitely six-and-a-half! They’re mostly inter-compatible, and making use of them means that you can access some pretty powerful peripherals easily. Let’s start with the two ecosystems that only have minor differences, and that you’ll encounter the most! Continue reading “The Connector Zoo: I2C Ecosystems”

Ask Hackaday: Repair Café Or Not?

A huge part of the work our community does, aside from making things and doing a lot of talking about the things we’d like to make, involves repair. We have the skills to fix our own stuff when it breaks, we can fix broken stuff that other people throw out when it breaks, and we can fix broken stuff belonging to other people. As our consumer society has evolved around products designed to frustrate repairs and facilitate instead the sale of new replacements for broken items this is an essential skill to keep alive; both to escape having to incessantly replace our possessions at the whim of corporate overlords, and to fight the never-ending tide of waste.

Repair Cafés: A Good Thing

So we repair things that are broken, for example on my bench in front of me is a formerly-broken camera I’ve given a new life, on the wall in one of my hackerspaces is a large screen TV saved from a dumpster where it lay with a broken PSU, and in another hackerspace a capsule coffee machine serves drinks through a plastic manifold held together with cable ties.

We do it for ourselves, we do it within our communities, and increasingly, we do it for the wider community at large. The Repair Café movement is one of local groups who host sessions at which they repair broken items brought in by members of the public, for free. Their work encompasses almost anything you’d find in a home, from textiles and furniture to electronics, and they are an extremely good cause that should be encouraged at all costs.

For all my admiration for the Repair Café movement though, I have chosen not to involve myself in my local one. Not because they aren’t a fine bunch of people or because they don’t do an exceptionally good job, but for a different reason. And it symbolically comes back to an afternoon over thirty years ago, when sitting in a university lab in Hull, I was taught how to wire a British mains plug.
