Peter Amstein, a volunteer who is president of the Board of the Museum of Communications, says early telephone technology shaped his IT career.

As Peter Amstein weaves his way through a maze of equipment racks clad in wire and stuffed with whirring machines, he gives a hilarious warning.

“There are open electrical terminals here, maybe nothing will kill you,” he says. “But there are definitely some things that make you feel pretty uncomfortable, so be a little careful with what you touch.”

Amstein works in the Seattle tech industry, but in his spare time he is a lead volunteer, tour guide, and president of the board of the steering group. Links Museum.

It’s where self-proclaimed tech geeks like Amstein preserve and restore the machines that ran America’s first landline telephone network.

This is Willy Wonka’s factory of rattling gizmos, many of which were invented by weirdos and steam age craftsmen who managed to connect the whole world.

“This is the story of a high-tech start-up, only it is 120 years old,” says Amstein.

In an era before computers and plastic, America communicated through the technology of the steam age and network systems designed by master craftsmen.

These days, Americans often communicate with other people through cars and computers, from text messages to dating apps and Zoom.

It’s easy to forget how we got here, how the telephone system shaped our first social network, and how its design still influences the way we speak today.

“So many things I’ve built my whole [tech] the career came from the telephone system, from the early developments,” says Amstein.

Voice over wire, the network that connects the world

Beginning in the 1870s, a group of inventors, including Alexander Graham Bell, figured out how to convert human voices into electrical signals and transmit them over wires.

Turns out that was the easy part. Once you understand how to help people communicate over long distances, you have to come up with a network that can connect the world of talkers.

The first step was human operators, usually women, who served as a kind of first software running the system.

“Should I gender stereotype you and ask you to be a telephone operator?” says Amstein, inviting the visitor to sit by the museum’s antique switchboard.

When she’s ready, he’ll teach her how to connect the cable one at a time. “Number please?” she asks, plugging in the cable and making the phone ring rapidly.

Public pay phones operated on a music call system that allowed operators to tell you if you had paid enough money to make a call.

At first, the technology that allowed women to run the network was improvised from things the inventors found everywhere, often as simple as musical chimes or bells.

For example, in the first generation of payphones, female operators listened to musical notes produced by coins of various sizes as they were dropped into the slot.

“She could hear it,” Amstein says. “Microphone was here [in the phone box]and she could hear the bells ringing.”

Smart, but very slow. Not practical if you want to connect thousands and then hundreds of thousands of people.

Craftsmen find ways to automate a growing system

The inventors then began to come up with steam age machines that could also listen and make connections much faster.

The device comes to life, sounding like a drummer beating the beat on a cymbal. When Amstein dials a number on the rotary phone, the Strowger switch registers short bursts of sound, counts them, and establishes connections with amazing accuracy.

This restored version of the Strowger switch from the Connection Museum collection was made by the Western Electric Company. The device relied on pulses from rotary telephones to figure out which connections to make.

Circuit breaker designs became faster and more reliable, binding America for more than a century. Then, in the late 1990s, computers came along, and machines like that were thrown out almost overnight.

“It’s a beautiful car”

Amstein demonstrates one of the prizes of the museum collection – a panel switch system that fills entire corridors of equipment racks.

“This is the last switch of its kind, the only working panel switch on the planet,” he says.

Imagine giant looms with cables connecting telephone lines up and down.

They found this machine mothballed and abandoned in a telephone company warehouse. One of the volunteers, Sarah Autumn, spent months putting it back together.

Sarah Autumn, a Museum of Communications volunteer, helped restore the complex panel telephone system, the last of its kind in operation in the world. The work took her over a year.

“It wasn’t easy,” she says. “It took me about a year just to dig into it before I could even begin to understand it really deeply.”

Like Amstein, Autumn works in the technology industry in Seattle.

When asked why she spent hundreds of hours of her free time to bring this device back to life, she speaks of it not as a broken device, but as a work of art.

“I fell in love with it because it’s a beautiful car,” says Autumn. “The people who worked on these systems were highly skilled and well versed in this complex web of interconnections.”

People who work here say that many of these machines are woven with neat engineering, important ideas that have been almost lost.

The technology seems ancient. But in the rumble and rumble of these old machines, you can see part of how America got to where we are now – the age of smartphones, TikTok and AI.

Roku is getting more and more into smart home hardware and the price is getting attention again. The company has disclosed Home Monitoring System SE kit including two entrance sensors, a motion sensor, a hub (with siren), and a keypad for $99. You can pay less for the entire monitor installation than for individual parts from competing kits.

As with earlier products, Wyze co-developed the hardware. You can track activity on your phone, but Roku unsurprisingly touts integration with its media players and compatible TVs. You may receive a login notification while watching a show. You can expand the system as needed, and the optional $100/year professional monitoring option uses Noonlight to provide immediate help from agents.

The SE home monitoring system is available today through Roku and Walmart and will arrive at Walmart stores in the US on May 19 along with a light strip and an outdoor solar panel. A Roku OS update that allows you to receive TV monitoring notifications (as well as camera history and voice control) should arrive in the “coming weeks.”

The expansion may seem strange for a company closely associated with streaming devices, but it comes at a critical moment for the company. The company is still laying off workers as it struggles with a difficult economy and is focusing on projects it thinks are more likely to pay off. Smart home products could help Roku supplement its core business by competing with Amazon and other companies that already have a wide range. household appliances.

The Los Angeles Police Department is upgrading the cameras in its patrol cars to capture wider angles at higher resolutions and allow video to be uploaded from location to location in the hope of increasing transparency with the police, Chief Michelle Moore said.

The LAPD is collaborating with axona private company based in Scottsdale, Arizona to install a new Axon Fleet 3 car camera systemwhich will be rolled out to all vehicles within a year, Moore said.

“We acknowledge [our current systems] are based on technology that is sometimes more than a decade old,” Moore said at a press conference on Thursday. “We know that when this happens with technology, you fall behind… Technology is constantly improving.”

According to the LAPD, the cameras will also record high-quality video in patrol cars and provide “knee-to-head” video in the passenger area and “enhanced night vision capabilities.”

The new Axon Fleet 3 will also allow LAPD officers to use their body cameras as a microphone, meaning they no longer need to carry separate microphones that can move around while interacting with civilians.

In addition to the new cameras at the LAPD park, Moore announced the installation of new cloud routers from the Boise, Idaho-based company. lullaby point which are installed in the back of black and white LAPD vehicles.

The Cradlepoint NetCloud Manager routers will quickly relay data from the patrol car back to the Los Angeles police stations so that watch officers can see things like body-worn video and new vehicle cameras, rather than information stored in the car.

Moore called the LAPD technology upgrades the “next step” in the department’s “modernization”.
