Feeling A Pong Of Nostalgia: Does It Hold Up In 2024?

We have probably all been there: that sudden memory of playing a (video) game and the good memories associated with said memory. Yet how advisable is it to try and re-experience those nostalgic moments? That’s what [Matt] of the Techmoan YouTube channel decided to give a whirl when he ordered the Arcade1Up Pong 2 Player Countercade game system. This comes loaded with multiple variants of the Pong game, including Pong Doubles and Pong Sports, in addition to Warlords, Super Breakout and Tempest. This unit as the name suggests allows for head-to-head two-player gaming.

This kind of ‘countercade’ system is of course much smaller than arcade versions, but you would expect it to give the Pong clones which [Matt] played as a youngster a run for their money at least. Ultimately [Matt] – after some multiplayer games with the Ms. – concluded that this particular nostalgia itch was one that didn’t have to be scratched any more. While the small screen of this countercade system and clumsy interface didn’t help much, maybe Pong just isn’t the kind of game that has a place in 2024?

From our own point of view of having played Pong (and many other ‘old’ games) on a variety of old consoles at retro events & museums, it can still be a blast to play even just Pong against a random stranger at these places. Maybe the issue here is that nostalgia is more about the circumstances of the memory and less of the particular game or product in question. Much like playing Mario Kart 64 on that 20″ CRT TV with three buddies versus an online match in a modern Mario Kart. It’s just not the same vibe.

Achieving Human Level Competitive Robot Table Tennis

A team at Google has spent a lot of time recently playing table tennis, purportedly only for science. Their goal was to see whether they could construct a robot which would not only play table tennis, but even keep up with practiced human players. In the paper available on ArXiv, they detail what it took to make it happen. The team also set up a site with a simplified explanation and some videos of the robot in action.

In the end, it took twenty motion-capture cameras, a pair of 125 FPS cameras, a 6 DOF robot on two linear rails, a special table tennis paddle, and a very large annotated dataset to train multiple convolutional neural networks (CNN) on to analyze the incoming visual data. This visual data was then combined with details like knowledge of the paddle’s position to churn out a value for use in the look-up table that forms the core of the high-level controller (HLC). This look-up table then decides which low-level controller (LLC) is picked to perform a certain action. In order to prevent the CNNs of the LLCs from ‘forgetting’ the training data, a total of 17 different CNNs were used, one per LLC.

The robot was tested with a range of players from a local table tennis club which made clear that while it could easily defeat beginners, intermediate players pose a serious threat. Advanced players completely demolished the table tennis robot. Clearly we do not have to fear our robotic table tennis playing overlords just yet, but the robot did receive praise for being an interesting practice partner.

Mouse Doesn’t Play Pong… It IS Pong!

From the “why didn’t we think of that” department comes [dupontgu’s] pong mouse project. The mouse appears and acts like a normal computer mouse until you click the scroll wheel. When you do, the mouse rapidly moves the cursor on the connected computer to play pong. Obviously, though, the paddles and the ball all look like your cursor, whatever that happens to be. So, how do you tell the score? Well, when a score happens, the cursor shows between the two paddles. In the middle means the game is tied. Otherwise, the player closest to the score indicator is winning. Continue reading “Mouse Doesn’t Play Pong… It IS Pong!”

2024 Tiny Games Contest: Pi-O-Scope-Pong

[Aaron Lager]’s Pi-O-Scope-Pong project takes a minimal approach to Pong by drawing on an oscilloscope to generate crisp paddles and ball. A Raspberry Pi takes care of the grunt work of signal generation, and even uses the two joysticks of an Xbox controller (connected to the Pi over Bluetooth) for inputs.

Originally, [Aaron] attempted to generate the necessary signals directly from the Pi’s PWM outputs by doing a little bit of RC filtering on the outputs, but was repulsed by the smeary results. The solution? An old but perfectly serviceable 8-bit MAX506 DAC now handles crisping up the visuals with high-quality analog outputs. Code is available on the project’s GitHub repository.

There isn’t any score-keeping or sound, but one thing that it has over the original Pong is a round ball. The ball in the original Pong game was square, but mainly because cost was a concern during design and generating a round ball would have ballooned the part count.

In many ways, Pong itself is a great inspiration for the Tiny Games Challenge, because the simplicity of its gameplay was likely a big part of its success.

Simple Version Of Pong Played On A Row Of LEDs

As far as video games go, Pong is already about as simple as it gets. But if even two dimensions is a bit more than you’re looking to tackle, [mircemk] shows how you can distill the core gameplay of this iconic title to its absolute minimum using an Arduino and a row of LEDs.

While [mircemk] brings their usual design aesthetic and flash to the project, this one could truly be done as a parts bin build. All you really need is a microcontroller with enough I/O pins (here, an Arduino Nano is used), a couple of buttons, and the aforementioned LEDs. A 16×2 LCD and a buzzer have been added to improve on the user interface a bit, but even that isn’t strictly required.

To play, each user holds their button and gets ready to hit it as soon as the LED closest to them lights up. Again, [mircemk] spruces this build up by offering both integrated buttons on the front panel of the game, as well as a pair of external “controllers” so you don’t have to crowd around the main unit. In this incarnation the score is shown on the LCD, but swapping that out for a pair of seven-segment LEDs could give the whole thing a bit more of a retro flair.

This isn’t the first time [mircemk] has tackled 1D Pong — if you can spring for addressable LEDs, you can pull the whole thing off with significantly less wiring.

A DIY handheld PONG game

DIY Pocket PONG Breaks The Mobile Spell

[Minikk], aka [Athul] is about to enter 10th grade and reports that they and their contemporaries are eschewing boring mobile games for 90s stuff and old games like PONG. Well, we already knew the 90s were back, but it’s nice to see that even older stuff is coming along with it. The kids are alright.

Whether you want to play alone or with a friend, it’s a classic to have in your pocket for sure. The brains behind this 70s-era operation is a Seeed Xiao ESP32-C3, which takes input from the two potentiometers and outputs the game on a 128 x 64 OLED. There’s also a small buzzer for when the ball hits the paddle, or you or your friend slips one past the goalie.

Our favorite part of this build has to be the DIY rivets that hold the OLED in place. [Athul] built posts into the enclosure that get heat-smashed into place with a soldering iron. Pretty neat, huh?

PONG is a specific thrill, certainly. How can it be more thrilling? Maybe with LEDs instead of a screen? Just a thought.

1D LED PONG, Arduino-Style

Maybe it’s just us, but isn’t it kind of amazing that in a world of pretty darn realistic games, PONG is still thrilling to play? This 1D implementation by [newsonator] is about as exciting as it gets.

It works like you’d probably expect — the light moves back and forth between the two players. Keep it in the green and you have a nice, gentle volley going. Let it hit your red LED and you’ve lost a point. But if you can push your button while your yellow LED is lit, the light speeds up tremendously until the next button press in the green.

Our only wish is that subsequent yellow-light button presses would make it speed up even more. But there are really just the two speeds with the current programming.

Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer. We like how [newsonator] wired up the LEDs to the Arduino by soldering them to a row of header pins and sticking that into the Arduino so it can be used in other projects down the line. We also like how [newsonator] shoved a couple of dowels through the box to ultimately support the two buttons.

Check out the intro video after the break for the overall details. The build is done over a few different short videos which follow.

Although this is pretty small, it isn’t quite the minimum viable.
