If you are old enough you’ll remember going to channel 3 to get gaming, and watching VHS, and a cable box in some instances. And you probably had to hand turn the knob!

Fun bit of history and explainer from VWestlife:

If you had a VCR, video game console, or computer connected to your TV via RF, in North America it was usually on channel 3, and sometimes on channel 4. But why those two channels? With a little knowledge of television broadcasting history and electronics, it’s actually not that hard to figure out.

Jason Snell, Six Colors:

These are companies playing the same game, but in different ways. Who’s ahead? I would argue that it’s impossible to tell, because if Apple had a product like Orion we would never see it. We can argue about whether Apple’s compulsion to never, ever comment on unannounced products is beneficial or not, but it’s a Steve Jobs-created bit of Apple personality that is very unlikely to be countermanded any time soon.

Here’s how tenuous the Orion prototype is. Meta claims it would cost $10,000, but they haven’t said whether that would be the cost of goods or the retail price. But let’s give them the benefit of the doubt and say that the retail price would be just $10,000 if they brought this to market today. That’s expensive. But it’s not ridiculous. You can buy high-end workstation-class desktops that cost that much. A fully-specced 16-inch MacBook Pro costs $7,200.

But according to The Verge, these Orion prototypes only get 2 hours of battery life. And they’re too thick and chunky. You look weird, if not downright ugly, wearing them. So Meta not only needs to bring the price down by a factor of at least 3× (which would put it around the $3,500 price of Vision Pro, which most critics have positioned as too expensive), they also need to make the glasses smaller — more svelte — while increasing battery life significantly. Those two factors are in direct contradiction with each other. The only easy way to increase battery life is to put a bigger battery in the device, which makes the device itself thicker and heavier. (See this year’s iPhone 16 Pro.)

Orion by all accounts is a really compelling demo. But it’s also very clearly a prototype device only suitable for demos. Even at $10,000 retail it wouldn’t be compelling today. Yet somehow Meta wants us to believe they have “line of sight” to a compelling consumer product at a compelling price.

It’s exciting that they showed Orion publicly, but I don’t think it helped Meta in any way going forward. There’s a reason why Apple didn’t show off a prototype iPhone in 2004.

Here’s an oral history of one of the greatest cyberpunk themed, hacking involved PC games of all time: System Shock! Here’s more from Rock Paper Shotgun:

[Austin Grossman, designer]: Everybody had seen the Ridley Scott films, and I was a huge fan of William Gibson. After all of the pretension and forced whimsy of the Ultima franchise, we just wanted things to be dirty and messy and futuristic for a while, which is what drove the aesthetic.

Marc LeBlanc, programmer: Origin wanted another Underworld, in space, and that is what we were pitching. How do you make a dungeon in space? Well, it’s going to be a space station. We imagined you were a hacker. We had physical augmentation and cyberspace. In the original pitch there was going to be terminal hacking, where you would sit down and start typing. That got cut, because it was too real at the time. That was like most people’s experience of a computer before Windows was really a thing – sitting down and typing in a text prompt.

This lamp designed by DavidF6 on Instructables cycles through billions of base pairs of DNA represented by red, purple, green and blue LEDs with help from an ItsyBitsy:

This LED lamp lights up the room with the full genetic code of humanity. It slowly reads off the DNA code from an SD card and displays the genetic base pairs as colors that move up through the helix. The four bases—A, T, G, and C— are represented as red, purple, green, and blue respectively. It has a power button as well as speed and brightness dials on the base. For the helix structure, I tried to make the proportions as close as I could to actual DNA. It’s a fun lamp to get lost in thought staring at. Because there are roughly three billion base pairs, it takes a long, long, long time to go through the whole thing.

After a relatively dry September, the rain has returned and the sun is setting earlier. How handy would it be to have an umbrella handy that also helps light your way home on your evening commute?

Leslie Birch has a great guide in our Learn system that shows you how to build your own LED Umbrella with NeoPixels

You can make it with either Circuit Playground or with FLORA.

You’ll be a rainbow in any storm with the FLORAbrella. With its NeoPixel LED strips and color sensor, you’ll be able to match your clothing, or display rainbow and rain patterns. Get ready to have an entourage at the next parade!

For this project, you’ll need to create the circuit, mount it in the dome of the umbrella, and then finish it off by creating clear vinyl hammocks for the battery and electronics.

Adafruit I2S MEMS Microphone Breakout – ICS-43434

Listen to this good news – we now have a breakout board for a super tiny ICS43434 I2S MEMS microphone. Just like ‘classic’ electret microphones, MEMS mics can detect sound and convert it to voltage, but they’re way smaller and thinner. This microphone doesn’t even have analog out, it’s purely digital. The I2S is a small, low-cost MEMS mic with a range of about 50Hz – 15KHz, good for all general audio recording/detection. The chip has a built in low-pass filter that cuts frequencies above 24KHz.

Gizmodo shares how archaeologists identified 1,309 potential glyphs, 303 figurative geoglyphs, and 42 newly identified geometric glyphs with the help of AI.

The Nazca Lines refer to a collection of these geoglyphs in the Nazca Pampa; between roughly 200 BCE and 500 CE, local groups removed the darker rocks on the arid landscapes surface, revealing the white sandy soil below. They did this on smaller scales but also on glyphs so large that they can only be properly seen from the air.

The lines are ancient but were rediscovered en masse in the 20th century; nevertheless, some went under the radar. In 2020, a feline geoglyph—as in, it depicts a cat—was found on a hillside in the region. Last year, two members of the recent team identified four new geoglyphs using an object detection algorithm, but they didn’t pursue a more comprehensive survey. Now, the larger team has done just that and been rewarded for their AI-assisted efforts.

In this Project Farm episode, Todd tests a bunch of end-cutting pliers to determine which ones are best. He tests Knipex, Milwaukee, Blue-Point, GearWrench, Channellock, Gedore, NWS, Tekton, Barnwell, Wazakura, Bates, Speedwox, Kseibi, Hautmec, WorkPro, American Mutt Tools, Performance Tools, and Irwin brand.

Todd compares the pliers for performance on the closeness of the flush cut, handle-force to cut through nails, screws, and drill bitd. Only one brand successfully cut through a hex key. Can you guess which brand reigned supreme? Yes, the Knipex (at $63 at time of testing) slayed the competition. But, the Wiha (at only $25) also performed surprisingly well.

Every September, the whole extended family at Relay FM raises money for St. Jude Children’s Research Hospital, one of the most amazing institutions in the world. St. Jude is dedicated to curing childhood cancer and helping families affected by it. Since 2019 Relay has raised over $3 million, and their best-ever single month was just north of $775,000.

This year they’re already at $925,000, within earshot of a cool million, with three days to go in the month. Let’s make that happen.

Update, 30 September: And, boom, they hit it: $1,041,913.31 and still counting.

In the midst of recording last week’s episode of The Talk Show with Nilay Patel, I offhandedly mentioned the age-old trick of holding down the Shift key while minimizing a window (clicking the yellow button) to see the genie effect in slow motion. Nilay was like “Wait, what? That’s not working for me...” and we moved on.

What I’d forgotten is that Apple had removed this as default behavior a few years ago (I think in MacOS 10.14 Mojave), but you can restore the feature with this hidden preference, typed in Terminal:

defaults write com.apple.dock slow-motion-allowed -bool YES

Then restart the Dock:

killall Dock

Or, in a single command:

defaults write com.apple.dock slow-motion-allowed -bool YES; killall Dock

Or, if you prefer a proper app to a command-line invocation, Marcel Bresink’s excellent TinkerTool.

Stanford University undergraduates have developed an inexpensive kit to bring the gene-editing technology to a classroom near you.

Matthew Lau, who is a co-first author on the paper, began working in the Qi lab while he was still a high schooler, after he attended a summer camp at Stanford. In 2018, Qi took him to a biotech conference in New York, where Lau saw a poster regarding an educational kit, which was expensive. That was the spark for making a DIY kit – something that could engage the community and bring science into the hands of students. The team focused on CRISPR because it was already a major part of Qi’s lab research.

James Hoffman takes an analytic approach to coffee. He studies grain consistency, tamp pressure, total dissolved solids, and much more all in persuit of the perfect cup. In this recent video he is looking for the most average espresso. He asked 39,425 people how they make espresso. If you like to nerd out on coffee science check out the stats!

We ran a survey to check out the state of global espresso in 2024 and nearly 40,000 people responded. Here’s some of the data! Do you have any hypotheses about what we found, or any other questions you think we should be asking of the data?

Thank you to all 39,425 of you who responded, and to Dr. Samo Smrke, Federick Ho (from University of Glasgow), and the Discord user who helped us process the huge quantity of data we received.

Craft the perfect, or average, cup with the Adafruit Learning System – Make sure your grind is right with John Park’s Coffee Detonator, and get precise ratio with Jan Goolsbey Clue Coffee Scale!

On Filament Friday, Chuck got tired of seeing all of these cool (but expensive) storage solutions for parts organizing boxes on channels like Adam Savage’s Tested. After finding some plastic parts organizers at the dollar store, he decided to design and 3D print brackets for them to create a wall-hanging storage solution for all of his electronics components.

You can find the storage boxes here and he’s made the STL files available if you want to print your own brackets.

Tom Pritchard, writing at Tom’s Guide:

We put the iPhone 16, iPhone 16 Plus, iPhone 16 Pro and the iPhone 16 Pro Max through the Tom’s Guide battery test, which involves surfing the web over 5G at 150 nits of screen brightness. The iPhone 16 Pro Max and iPhone 16 Plus have risen to the top with some incredibly impressive results — making our best phone battery life list in the process. Here’s how the new iPhone 16 models’ battery life stacks up against their iPhone 15 counterparts, and rival flagships.
