Popular YouTuber shows how the 1980s' gaming 'light guns' actually worked

Add as a preferred source on Google

Every nerd of a certain age has a slight weakness for 1980s technology — and thanks to shows like Stranger Things, there has never been a better time to get nostalgic about the decade that gave us big hair, the Nintendo Entertainment System, and peak Steven Spielberg.

One person who is capitalizing on this trend is popular YouTuber David Murray, aka The 8-Bit Guy, whose YouTube channel offers fun science lessons in the inner workings of our favorite retro gadgets. In his latest video, Murray shows us how two “must have” bits of gaming tech — the Light Pen and NES Zapper gun — worked.

Since being posted just a few days ago, the video has already racked up more than 400,000 views and shows no sign of slowing down, either.

“The response to this video has been amazing,” Murray told Digital Trends. “In the last 24 hours, I’ve had more than 1,000 emails. I’m trying my best to answer them all.”

The video is an entertaining deep dive into technology that seemed incredibly futuristic at the time, but which we never thought too much about the science that made it possible. What is impressive is how ahead-of-its-time tools like the Light Pen and NES Zapper gun actually were and how well they worked in some cases, despite the comparatively basic tech involved.

While Murray now has plenty of videos to his name, in this case, he said the video took a while to put together because of the challenge of finding one of the somewhat-rare light pens available for sale.

“In a lot of cases with these technologies, I have to track down and buy the things I want to show,” he noted. “I’ve been searching for a light pen on eBay for some time now, but they don’t show up so often because they’re rare. Eventually, I found one for $40, so when it arrived, I figured it was time to do this video.”

AMD is quietly building a frame generation mode that beats Nvidia at its own game
AMD's next frame generation trick might make your GPU pump out seven extra frames for free.

AMD has been hinting at Multi-Frame Generation for its Radeon cards for a while now, and it looks like the company is further along than it has let on. Preliminary support quietly showed up in the ADLX FidelityFX SDK back in April with the FSR Redstone update, letting users pick a frame generation ratio for the best mix of performance and image quality.

Since then, AMD has shipped several big driver updates, including FSR 4.1.1. As reported by Wccftech, a user on the Chiphell forums used a tool called RadeonTuner to dig through the Adrenalin 26.6.2 WHQL drivers and found options AMD has not talked about publicly. RadeonTuner is a cleaner, more user-friendly take on the Adrenalin software, and it can surface features that live inside the driver but never appear in the official app.

I wouldn’t have recommended this Nintendo Switch 2 accessory before, but this deal changes everything
Nintendo Switch 2

Buying a Nintendo Switch 2 isn't exactly cheap these days, especially after Nintendo's recent US price adjustments. That's why it's refreshing to see one of the console's accessories getting an unexpectedly deep discount.

If you've ignored the official Nintendo Switch 2 Camera because it seemed overpriced, now might be the perfect time to take another look. GameStop has slashed the accessory to just $10, a huge drop from its regular $55 asking price. That's roughly 82% off, making it one of the best Switch 2 deals we've seen in a while. To put that into perspective, the camera now costs less than many Switch 2 carrying cases or screen protectors. At this price, it's much easier to take a chance on an accessory you may have skipped at launch.

Well… at least God of War Laufey is getting a physical disc

Last week, Sony lit the gaming community on fire by announcing that all new PlayStation games released from January 2028 onwards would be digital-only, effectively bringing an end to physical discs for future releases. At the same time, the company also confirmed it would shut down the PlayStation 3 and PS Vita digital stores by July 2027, reinforcing concerns that digital storefronts and the games tied to them don't last forever. Unsurprisingly, the announcements triggered widespread backlash from collectors and long-time PlayStation fans. In the middle of all that, Santa Monica Studio offered a surprisingly comforting update: God of War Laufey will be available on disc. It's only one sentence, but it says a lot.

More than just a physical release
