Tech History with Fexingo: Stories of Silicon Valley, Pioneers, and Industry Origins

In 1975, Kodak engineer Steven Sasson built the first digital camera — a toaster-sized device that captured 0.01-megapixel black-and-white images onto a cassette tape. This episode explores how that prototype, dismissed by Kodak executives as a threat to film, eventually led to the smartphone camera revolution. Lucas and Luna walk through the technical challenges of building a CCD-based camera wit...

In 1975, a Kodak engineer named Steven Sasson built the first digital camera — a prototype the size of a toaster that captured 0.01 megapixel black-and-white images onto a cassette tape. This episode tells the story of how Sasson's invention was met with skepticism inside Kodak, why the company buried the technology for decades, and how that decision reshaped the photography industry. We also expl...

In 1988, a Cornell graduate student named Robert Tappan Morris released what would become the first computer worm to spread across the internet—and it wasn't malicious. Episode 77 of Tech History with Fexingo revisits the Morris Worm, a pivotal moment that taught the early internet a harsh lesson about security. We trace how a small programming error turned an experimental tool into a digital disa...

In this episode, Lucas and Luna trace the origin of the computer mouse from its invention by Doug Engelbart at SRI in 1964 to its refinement at Xerox PARC in the 1970s. They explore why the mouse initially flopped, how Steve Jobs saw it at PARC and adapted it for the Macintosh, and why the mouse we use today still bears the fingerprints of those early prototypes. Along the way, they touch on the p...

In this episode, Lucas and Luna explore the origins of Wi-Fi, focusing on the creation of the 802.11 standard in 1997. They discuss how the IEEE committee brought together competing technologies from companies like AT&T and Lucent, the role of Vic Hayes as 'the father of Wi-Fi,' and how interoperability was achieved despite technical challenges. The hosts also touch on the surprising 2.4 GHz band...

In episode 74 of Tech History with Fexingo, Lucas and Luna explore the origin of the integrated circuit—the microchip—and how its invention by Jack Kilby at Texas Instruments in 1958 and Robert Noyce at Fairchild Semiconductor in 1959 set the stage for Silicon Valley's ecosystem. They discuss the patent race, the 'traitorous eight' who left Shockley Semiconductor, and how Fairchild's spin-offs cre...

In this episode of Tech History with Fexingo, Lucas and Luna explore the story behind the first Voice over IP call in 1995—how VocalTec's InternetPhone software let two users talk over the internet, bypassing phone companies and setting the stage for Skype, Zoom, and an entire industry. They dive into the technical breakthrough, the regulatory pushback, and the lasting impact on global communicati...

In this episode, Lucas and Luna explore the unlikely origins of the first commercial microprocessor—Intel's 4004, released in 1971. They dive into how a Japanese calculator company's request for a custom chip led to a breakthrough that consolidated an entire computer's central processing unit onto a single sliver of silicon. Lucas explains why Intel initially didn't see the potential, how the 4004...

In 1958, AT&T introduced the Bell 101 modem, a device that let computers speak over ordinary phone lines at a blistering 110 bits per second. This episode traces how that clunky box made remote terminals, time-sharing, and eventually the internet possible. Lucas and Luna explore the technical constraints, the surprising role of SAGE air defense, and why the Bell 103's 300 baud standard solidified...

In 1991, scientists at the University of Cambridge built a camera pointed at a coffee pot to avoid wasted trips to an empty pot. That grainy black-and-white image, refreshed three times a minute, became the first webcam. We trace the story from the Trojan Room to the birth of live video on the internet, and how a simple convenience tool foreshadowed Zoom, Twitch, and surveillance culture. #Webcam...

In this episode of Tech History with Fexingo, Lucas and Luna explore the surprising origin of the optical mouse. While most people think of the mechanical mouse with a rolling ball, the first optical mouse was actually invented in 1980 by two engineers at Xerox PARC. But it didn't use a red LED—it used a laser and a special patterned grid to track movement. The hosts trace the story from that earl...

In 1988, the Morris worm brought the internet to its knees, infecting 6,000 of the 60,000 computers then online. That same year, a young German programmer named Bernd Fix wrote the first dedicated anti-virus program to kill a specific malware strain. This episode traces the cat-and-mouse birth of digital defense: from the Vienna virus and the Pakistani Brain boot-sector infection to the launch of...

In this episode, Lucas and Luna explore the forgotten story of the IBM 3340 Direct Access Storage Facility — better known as the Winchester drive. Launched in 1973, it revolutionized data storage with its sealed, removable module design, offering 30 megabytes of storage for a fraction of the cost of earlier disk drives. They trace how IBM's gamble on a self-contained, low-cost drive changed enterp...

In this episode of Tech History with Fexingo, Lucas and Luna dive into the birth of the transistor at Bell Labs in 1947. They explore how John Bardeen, Walter Brattain, and William Shockley created a tiny device that replaced vacuum tubes and launched the semiconductor revolution. Lucas explains the science behind the point-contact transistor and why it was such a breakthrough, while Luna brings i...

In episode 65 of Tech History with Fexingo, Lucas and Luna explore the origin of email — from Ray Tomlinson's 1971 experiment on ARPANET to the choice of the @ symbol. They discuss why the first test message was something like 'QWERTYUIOP', how email grew from a simple file transfer hack into the backbone of modern communication, and what that early moment tells us about invention under constraint...

In this episode of Tech History with Fexingo, Lucas and Luna explore the invention of the first laser printer by Xerox PARC in 1971.

The hosts discuss how this breakthrough sparked desktop publishing and the laser printer market that today ships over 3...

In this episode of Tech History with Fexingo, Lucas and Luna explore the origin of Ethernet, the networking technology that underpins the modern internet. They focus on the pivotal moment in 1973 when Bob Metcalfe at Xerox PARC sketched the first Ethernet design on a napkin, inspired by ALOHAnet, a radio network in Hawaii. The hosts explain how Ethernet evolved from a 2.94 Mbps experimental system...

In this episode, Lucas and Luna trace the origins of computer programming back to Ada Lovelace and her work on Charles Babbage's Analytical Engine in the 1840s. They discuss how Lovelace wrote what is widely considered the first algorithm intended for machine execution, why it was so far ahead of its time, and how the initial vision of computing as a universal symbol manipulator differs from the p...

In this episode of Tech History with Fexingo, Lucas and Luna dive into the story of the Morris Worm, the first major computer worm to spread across the internet in 1988.

Released in 1972, the Odyssey was the first commercially available video game console, built by Ralph Baer and his team. They discuss how Baer, a television engineer, proposed the idea of interactive TV in 1951, and how his 'Brown Box' prototype...

In 1991, researchers at the University of Cambridge pointed a camera at a coffee pot to save themselves a wasted trip. That makeshift setup—the Trojan Room coffee pot—became the world's first webcam, streaming live images over the early internet to a handful of desktop computers. Lucas and Luna trace the story from the original grainy 128x128 greyscale frames to the modern era of billions of conne...

Long before the iPhone, a device called the IBM Simon Personal Communicator hit shelves in 1994 for $899—$1,900 in today's money. It had a touchscreen, could send emails, and even ran third-party apps. But it flopped. In this episode, Lucas and Luna dig into why the Simon failed, what it got right, and how its innovations quietly shaped every smartphone that followed. They explore the technical co...
