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

How light pens and light guns work NES Zapper
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.”

All Baobab Tree locations in Tales of Kenzera
Zau fights a dragon in Tales of Kenzera: Zau.

While it wasn't marketed as being a particularly punishing game, Tales of Kenzera: Zau is by no means easy. You will have plenty of environmental challenges that can instantly sap your life, and the enemies you face -- especially the bosses -- are no slouches. When you first begin, it will only take a couple of bad hits to send Zau to the land of the dead himself. Alongside the Trinkets you can unlock through hidden challenges around the map, there are also Baobab Trees where Zau can stop to reflect on his journey thus far, have a short dialogue with Kalunga, and get a small addition to his health bar. Like everything in the game, these trees aren't prohibitively hidden, but you could easily pass one by and have no idea where it was when trying to backtrack. These are all the Baobab Tree locations so you can max out your health bar.
All Baobab Tree locations
There are six Baobab Trees to find in Tales of Kenzera: Zau and each adds a small segment of health to your total. When you collect them all, you will roughly double your HP bar. Here are each of their locations in the rough order you should naturally find them in. Most can be picked up on your first time through that area.

This one is very hard to miss as it is directly on your critical path. If you do, you can fast travel to the nearby campfire to grab it.

All Fallout games, ranked
The courier in his nuclear gear and holding his gun in Fallout: New Vegas key art.

Who would've thought the post-apocalypse could be such a fun time? The Fallout franchise has taken the idea of a Mad Max-like future and not only made it into a wildly popular game franchise but also a hit TV series. The core franchise has been around since the late '90s, and yet we've had only a handful of mainline entries in the series since it was revived by Bethesda with Fallout 3. With Starfield in the rearview mirror and the next Elder Scrolls title currently being the dev team's focus, it could be close to another decade before we can set foot in the wasteland ourselves once again. What better time, then, to look back at the franchise and rank all the games from best to worst?
