Grannophone Helps You Stay In Touch

September 10, 2023 by Kristina Panos 20 Comments

Whether it’s distance, pandemics, or both that separate you from your elderly loved ones, what’s the best idea for communicating with them so they don’t suffer from loneliness on top of issues like dementia? We’d say it’s probably something like [Stefan Baur]’s Grannophone.

Back in late 2020, a Twitter user named [Nitek] asked the Internet what could be done in the way of a grandma-friendly video-conferencing solution, provided Grandma has a TV and a broadband internet connection. At first, [Stefan] was like, just get her an old iPad and FaceTime with her. But the question got him thinking. And prototyping.

Grannophones are essentially Linux machines with a video-capable SIP client connected over a VPN for privacy reasons. In simple mode, picking up the handset of one Grannophone will call the other, but more complicated configurations are possible. We particularly like that replacing the handset automatically obscures the camera. That’s a nice touch.

At this point, the Grannophone is a work in progress. The idea is that they be extremely easy to build at the kitchen table, like on the order of disposable Swedish furniture. If you can contribute to the project, please do. Be sure to check out the demonstration video after the break.

On the other hand, if Granny is 1337, you could always video-conference in terminal.

Open Deck Is Your Window To Shortcuts

September 10, 2023 by Kristina Panos 11 Comments

Once in a while, we see projects that could easily pass for commercial products. This is one of those projects: a (surprisingly) low-cost DIY macro pad from [Josh R] that was designed to be a cheaper alternative to the various stream decks out there. Between the carbon fiber top plate and the crystal-clear acrylic keycaps, this is quite the elegant solution.

This lovely little macro pad is built around the ESP8266, specifically the WEMOS D1 Mini V4. However, the most vital part to get right is the screen, which must be a 128 x 160 TFT display in order to line up with the 3D printed frame that divides it into fourths. Custom parts like the acrylic keycaps and the carbon fiber top plate are available on Tindie if you don’t have access to a CNC.

Operationally, Open Deck has a nice-looking GUI. Once programmed, each shortcut is capable of having three beneath it, with the fourth button reserved for Home. Be sure to check out the extremely satisfying build video after the break.

Want a stream deck, but don’t want to build it? Just dig up an old phone or tablet.

Raspi-Powered Typewriter Is A Real MUSE

September 5, 2023 by Kristina Panos 4 Comments

Thanks to parenting and life in general, [Brendan] had fallen out of the habit of writing and wasn’t happy about it. If you write anything ever, you already know there are endless distractions when it comes to doing so on a computer. Sure, there always typewriters, but it’s difficult to do anything with the fruits of a typewriter other than scan it in or make copies, and it’s basically un-editable except by hand.

Instead of just sitting down and writing, [Brendan] did what any of us would do — took the time to create an elegant solution. The Most Unusual Sentence Extractor, or MUSE, is a Raspberry Pi-based typewriter with the best of both worlds. It’s essentially a word processor, but it can save to the cloud.

[Brendan] found beautiful inspiration in the Olympia Traveller de Luxe typewriter, a delightfully boxy affair made in the 1960s and 70s with lovely keys. Starting with a 68Keys.io board, [Brendan] set about re-creating the lines of the Traveller de Luxe in Tinkercad.

Since it doesn’t really need a platen, this was the perfect place to mount a screen using black PVC. At first, [Brendan] was going to use an e-ink screen, but a mishap led to a better solution — an LCD touchscreen that makes document navigation a breeze.

We absolutely love the look of this machine, which was obviously a labor of love. And yeah, it does the trick:[Brendan] is writing again. Though it maybe be inconvenient, we agree that it really is nice to have a dedicated workstation for certain things.

Looking for the complete opposite of this project? How about a Chat GPT-assisted daisywheel typewriter?

Spooky Noise Box Has Post-Halloween Potential

September 5, 2023 by Kristina Panos 8 Comments

There’s more than one way to scare people on Halloween. Sure, there’s always the low-brow jump scare, but that will generally just annoy the person and possibly cause a heart attack. No, what you need is a sustained soundscape of hellish audio. And where does one find hellish audio? Well, you make your own with a spooky-sounds noise box.

And no, we’re not talking about a soundboard that goes ‘boo’ and ‘ooo-OOO-oooh’ and whatnot. This is a full-on DIY instrument that has potential beyond Halloween. Essentially, the wooden box takes input vibrations from various doodads, and these vibrations are picked up by a piezo disk or two glued to the underside of the lid. The piezos are wired up to a 3.5 mm jack, which runs out to the PC and [SvartalfarQc]’s favorite Digital Audio Workstation (DAW). From there, it’s just a matter of playing around with the sounds — looping them, running them through various instrument voices, adding effects, and so on.

We love the the things that [SvartalfarQc] came up with, including a wind-up walking heart thing, a retractable badge holder, and that noise box mainstay, a sproingy doorstop.

We all know piezos are awesome, but have you ever considered that they can be used to digitize old wax cylinder recordings?

You’ve Got Mail: Straining The Limits Of Machine And Man

September 5, 2023 by Kristina Panos 10 Comments

When we last left this subject, I told you all about Transorma, the first letter-sorting machine in semi-wide use. But before and since Transorma, machines have come about to perform various tasks on jumbled messes of mail — things like distinguishing letters from packages, making sure letters are all facing the same way before cancelling the postage, and the gargantuan task of getting huge piles of mail into the machines in the first place. So let’s dive right in, shall we?

The ‘Scope Of This Kickstarter? Ten Years.

September 4, 2023 by Kristina Panos 18 Comments

It may have taken ten years to come through on this particular Kickstarter, but a promise is a promise. In late August 2023, backers who had since likely forgotten all about the project started receiving their oscilloscope watches from creator [Gabriel Anzziani]. Whatever the reason(s) for the delay, the watch looks great, and is miles ahead of the prototype pictures.

As you may have guessed, it functions as both a watch and an oscilloscope. The watch has 12- and 24-hour modes as well as an alarm and calendar, and the ‘scope has all the features of the Xprotolab dev board, which [Gabriel] also created: ‘scope, waveform generator, logic analyzer, protocol sniffer, and frequency counter.

Internally, it has an 8-bit Xmega microcontroller which features an internal PDI, and the display is a 1.28″ E ink display. When we covered this ten years ago, the screen was the type of Sharp LCD featured in the Pebble watch. [Gabriel]’s ‘scope watch features eight buttons around the edge which are user-programmable. One of [Gabriel]’s goals was for people to make their own apps.

Of course, the Kickstarter rewards are no longer available, but if you want to build your own small, digital ‘scope, check out this DIY STM32 project.

Labor Day BBQs May Feature NYPD

September 1, 2023 by Kristina Panos 53 Comments

Planning to host a large backyard wingding in the NYC metro area this weekend? Be sure to watch the skies for uninvited guests. That’s right, the NYPD are deploying drones over “large” Labor Day events and yes, even private barbecues. The strategy was announced during a briefing about J’ouvert — that’s a yearly Caribbean festival that marks the end of slavery. It generally brings crowds of thousands and draws a strong police presence to Brooklyn.

While this particular invasion may come as a bit of a shock, this certainly isn’t the first time the NYPD has deployed drones in the name of public safety or in response to emergencies. Data shows they have used them 124 times this year, which is up a staggering 31 times from the four events in 2022.

As you may have guessed, this has invited backlash from privacy and civil liberties advocates. One pointed out that this action “flies in the face of the POST Act,” a city law that requires the NYPD to provide transparency about their various surveillance tactics. The advocates cite the fact that regulations have not kept up with the proliferation of technology.

No matter what happens in the future with regulations, the NYPD can always crash large parties the old fashioned way. Usually, the neighbors will complain at some point, unless they were all invited.
