DSL Is Barely Hanging On The Line As Telcos Stop Selling New Service

October 29, 2020 by Kristina Panos 170 Comments

Are you reading this over AT&T DSL right now? If so, you might have to upgrade or go shopping for a new ISP soon. AT&T quietly stopped selling new traditional DSLs on October 1st, though they will continue to sell their upgraded fiber-to-the-node version. This leaves a gigantic digital divide, as only 28% of AT&T’s 21-state territory has been built out with full fiber to the home, and the company says they have done almost all of the fiber expansion that they intend to do. AT&T’s upgraded DSL offering is a fiber and copper hybrid, where fiber ends at the network node closest to the subscriber’s home, and the local loop is still over copper or coax.

At about the same time, a report came out written jointly by members of the Communications Workers of America union and a digital inclusion advocacy group. The report alleges that AT&T targets wealthy and non-rural areas for full fiber upgrades, leaving the rest of the country in the dark.

As the internet has been the glue holding these unprecedented times together, this news comes as a slap in the face to many rural customers who are trying to work, attend school, and see doctors over various videoconferencing services.

If you live in a big enough city, chances are you haven’t thought of DSL for about twenty years, if ever. It may surprise you to learn of the popularity of ADSL in the United Kindom. ADSL the main source of broadband in the UK until 2017, having been offset by the rise of fibre-to-the-cabinet (FTTC) connections. However, this Ofcom report shows that in 2018 ADSL still made up more than a third of all UK broadband connections.

Why do people still have it, and what are they supposed to do in the States when it dries up?

An Automatic Label Dispenser For Quicker Stickers

October 28, 2020 by Kristina Panos 10 Comments

If you have any kind of business, chances are it involves stickers at some point in the process. More accurately it involves you peeling the backs off of sticker after sticker, slowly wasting time and working your way toward a repetitive stress injury. Why do that to yourself when you could have a machine do it for you?

That’s exactly the thinking behind [Mr Innovative]’s automatic label dispensing machine. All he has to do is load up the roll of labels, dial in the length of each label, and away the machine goes, advancing and dispensing and taking up the empty paper all at once. In fact, that’s how it works: the take-up reel is on the shaft of a NEMA-17 stepper motor, which gets its instructions from an Arduino Nano and an A4988 motor driver. Our favorite part is the IR sensor located underneath the sticker that’s ready to take — the machine doesn’t feed another until it senses that you’ve taken the previous sticker. We stuck the demo and build video after the break.

Our other favorite thing about this build is that [Mr Innovative] seems to have used the same PCB as his freaky fast bobbin winder.

Circuit Sculpture Breathes Life Into Discrete Components

October 27, 2020 by Kristina Panos 5 Comments

We’ve probably all given a lot of thought to breathing this year in various contexts. Though breathing is something we all must do, this simple act has become quite the troublemaker in 2020. They say the best art imitates life, and [bornach]’s Astable Exhalation certainly does that, right down to the part about astability. It’s especially interesting that the end result — breathing, visualized — is so calming, it could almost be a meditative device.

There is nary a microcontroller to be found on this circuit sculpture, which uses a pair of astable multivibrator(s) to light two sets of LEDs that represent air being inhaled and exhaled. We like that [bornach] used two sized of exhale LEDs to represent droplets and aerosols in this beautiful circuit sculpture, and we love that most of the components were scavenged from old electronics and older projects.

Our Circuit Sculpture Challenge runs until November 10th, so even if you’re waiting to take the Remoticon workshop before entering, there’s still a little bit of time to whip something up afterward in the post-con adrenaline rush phase. If you need inspiration, check out some of the other contest entries or just surf through all things circuit sculpture.

POV LED Staff Takes Art For A Spin

October 25, 2020 by Kristina Panos 9 Comments

The human body does plenty of cool tricks, but one of the easiest to take advantage of is persistence of vision (POV). Our eyes continue to see light for a fraction of a second after the light goes off, and we can leverage this into fun blinkenlight toys like POV staffs. Sure, you can buy POV staffs and other devices, but they’re pretty expensive and you won’t learn anything that way. Building something yourself is often the more expensive route, but that’s not the case with [shurik179]’s excellent open-source POV staff.

There’s a lot to like about this project, starting with the detailed instructions. It’s based on the ItsyBitsyM4 Express and Adafruit’s Dotstar LED strips. You could use the Bluetooth version, but it’s already quite easy to load images to the staff because it shows up as a USB mass storage device. We like that [shurik179] added an IMU and coded the staff so that the images look consistent no matter how fast the staff is spinning. In the future, [shurik179] might make a Bluetooth version that’s collapsible. That sounds like quite the feat, and we can’t wait to see it in action.

As cool as it is to wave a POV staff around, there’s no real practical application. What’s more practical than a clock?

Don’t Guess, Listen To Your Plants’ Pleas For Water

October 23, 2020 by Kristina Panos 5 Comments

Plants are great to have around, but they all have different watering needs. If only they could cry out when they’re thirsty, right? Well, now they can. All you need to hear them suffer is your very own Klausner Machine. [RoniBandini] based the Klausner machine on one of Roald Dahl’s short stories, which features an inventor who builds a machine that can make audible the sound of plants shrieking whenever they’re cut.

In [RoniBandini]’s version of the Klausner Machine, the point is to judge the plant’s feelings based on its soil moisture content. An Arduino Nano reads in from the soil moisture sensor, and if the soil is dry, the plant screams. If the soil is moist, the plant emits happy sounds from DF Player Mini and SD card. We think the analog meters are a great touch, and the jumping needles really anthropomorphize the plant.

Go forth and gain a better appreciation for your plants’ feelings, because this project is wide open. Maybe it will help you water them more often. Some plants need to be cut back, so we think it would be cool if you could make it scream when you take a cutting. Check out the demo after the break.

This is isn’t the first time we’ve seen an analog meter used in conjunction with soil moisture. What is a VU meter, anyway? Our own [Dan Maloney] really moved the needle on the subject a while back.

Trick Or Yeet Cannon Will Give Them Candy Shell Shock

October 23, 2020 by Kristina Panos 11 Comments

One of our favorite things about Halloween is the sheer number of hacks that come out of it each year. This year, hacking is almost a requirement to keep things physically distanced, but that doesn’t mean we can’t have fun. You want fun? How about a candy cannon that launches sweet projectiles at trick-or-treaters from fifty feet?

[Paul McCabe]’s cannon uses a sprinkler valve and an air compressor to launch a pair of fun size candy bars, each encased in a film canister shell. Each trick-or-treater stomps a foot switch fifty feet away at the end of the driveway, and as long as someone is there holding down the primary ignition, the cannon will fire with a nice retort that sounds like a large wind instrument playing a D note.

We were sad to learn that the parachute idea didn’t shake out, but the glow sticks are a great addition for night time. Check out the demo after the break, which is followed by a build video and then some more launches for the fun of it. Don’t have enough time to build a cannon of this caliber? You could put a spooky six-foot slide together pretty quickly.

Clacker Hacker: Popping A Cap In A Brother EP43 Thermal Typewriter

October 22, 2020 by Kristina Panos 27 Comments

A few months ago, I fell down the internet rabbit hole known as Ted Munk’s typewriter site. I don’t remember if I just saw this Brother EP43 typewriter for sale and searched for information about them, or went looking for one after reading about them. Either way, the result is the same — I gained a typewriter.

Now I’m not really a typewriter collector or anything, and this is my first word processor typewriter. When it arrived from Goodwill, I anxiously popped four ‘C’ cells in and hoped for the best. It made a print head noise, so that was a good sign. But almost immediately after that, there was a BANG! and then a puff of smoke wafted out from the innards. My tiny typewriter was toast.
