TV show inspires this smaller Pong paddles hardware hack

smaller-pong-paddles

When we read “smaller paddles” we immediately thought of the physical controllers that you hold in your hands. But this hack alters the size of the virtual Pong paddles displayed on the TV screen.

We remember quite well the episode of That 70′s Show where Red and Kelso take apart their Pong machine to hack it. The video after the break which [Blues Image] put together shuffles scenes from that episode in with images of his hack. The characters are adamant that the game is too easy and reducing the size of the virtual paddles is the only thing that will make it fun again. After building his own hardware from the original schematics, [Blue Image] figured this challenge was worth a try.

His solution is in the form of two man-in-the-middle boards which insert a way to reroute the pins without altering the main board. One of the chips is used to draw the paddles, the other checks for collisions with the ball. By changing the pin-out the paddles are reduced from fifteen pixels down to seven.

Gaming system inside an Atari joystick

gaming-system-inside-an-atari-controller

This original Atari controller is pretty small (take a look at that RCA cable for a sense of scale). Despite it’s size, [Kyle Brinkerhoff] managed to fit a complete gaming system inside the controller. This Pocket Sized Atari is a follow-up to another project he did called ArduPong which let him play Pong using a joystick and an Arduino. This rendition takes the external project box from that build and moves everything into one tight little package.

In the video after the break [Kyle] gives us a tour of the internals. The Arduino board he went with is an Ardweeny which is no bigger than the ATmega328 footprint so it can be easily mounted off to one side. The joystick internals have been replaced with the analog stick module from a PlayStation controller. That is where the button came from as well. Just connect this to a 9V battery and the composite video input of a TV and you’re ready to do some gaming!

Now if you just want that retro look for your Xbox Live games check out this Xbox 360 controller in an Atari joystick.

Fabricating hardware from the original arcade Pong schematics

original-arcade-pong-rebuild

This heavily populated PCB is a recreation of the original arcade version of Pong. That is an important distinction because the home version of Pong used a specialized chip to do much of the work. This is basically all stock logic, which explains the high component count. We wonder how many quarters it took just to pay for all 66 chips at the time?

[Pong74ls] was the person who took on this project. There is an original schematic available, but it’s incredibly crowded and rather difficult to figure out. Fortunately [Dan Boris] has already done a lot of the heavy work. He took the one-page nightmare and turned it into a sixteen page plan for building the original board (look for the schematic link under technical details).

Before the board could be laid out some redesign work was necessary. It sounds like some of the original chips are out of production and suitable replacements needed to be found. The board was then laid out in Eagle before sending the design off to a fab house. There was just one error which didn’t allow the ball to bounce when hitting a paddle while travelling downward. A couple of jumper wires fixed that right up!

Building Pong for an 8-pin micro

pong

For playing around with video signals and trying to create a an interesting microcontroller project, you can’t do better than the classic Pong. We’ve seen our share of microcontroller-based pong builds, but rarely have we seen an 8-pin microcontroller recreate every part of the first video game.

[Tim] started his PIC12F1840-based Pong build with just a few buttons for controls and a video output. This in itself is somewhat of an achievement, as [Tim] used all the data memory and every GPIO pin on this small microcontroller.

He had time to optimize his build and ended up adding the bleeps and bloops of the original Pong to his build. He’s got an interesting design on his hands, and also what is probably the smallest Pong clone in existence.

monoPong: A CMOS 1-D Pong

We’ve seen a few 1-D pong games recently, and they’ve all be controlled using microcontrollers. Inspired by some of these hacks, [mischka] built the monoPong using a handful of logic chips.

The monoPong has four major components. A 555 timer in astable mode provides a clock source which is fed into a 4510 decade counter, which connects to a 4028 BCD to decimal decoder to drive the LEDs. Finally, a 4011 NAND gate IC is used to deal with the button presses. Two of the NAND gates form a RS flip-flop, and the other two NAND each player’s button with the last LED on the player’s side of the strip. If the player hits the button when their LED is on, the RS flip-flop toggles and changes the decade counter from count up to count down mode. This makes the ball bounce back.

[mischka] finished the project off by putting it in a wooden box and drilling holes for the LEDs, buttons, and a power switch. The final product looks pretty good, and is a great example of how you can use a couple logic chips instead of a microcontroller.

After the break, watch a quick game of monoPong.

One dimensional PONG, take two

Needing a Christmas present for his 4- and 5-year-old nieces, [John] built a one-dimensional PONG game, sure to be the delight of rosy-cheeked children on a Christmas morn.

The new and improved 1D PONG game is built around a digital RGB LED strip with an LPD8806 LED controller. The speed of the ‘ball’ is controlled by a pot on one side of the game. With each player pressing their button at the right time, the ball bounces back to the other player. Missing the ball awards a point to the other team and most likely an increase in the player’s frustration, greatly increasing the risk of this game being thrown across the room.

While it’s not an obscenely long 1D PONG game like [Jason]‘s previous 5 meter version, it’s more than enough to keep a pair of kids occupied for more than a few minutes, a remarkable achievement for just a microcontroller, buttons, and a piece of LED strip.

You can get [John]‘s AVR code in this pastebin or just check out the video after the break.

Retroball or Super Pong Table Grows Up

pong-table

Retroball is, as its Kickstarter campaign says, “Retro Fun for up to Four Players.” What you might not know, is that it’s ancestor was featured here earlier last year. With a year and a half of development underway, the build looks spectacular, and the people in their promo video look like they’re having lots of fun (obviously).

The whole concept of the game is that it has up to four players that each manipulate a paddle as in the classic Pong game. The obvious difference is that there are four players, and everything is played on a 32 x 32 LED array.

Although it looks like fun in it’s stock form, readers of Hack a Day will most likely start thinking about how they could modify it for their own uses. Everything is open source, and they promise to release the documentation for this project. On the other hand, if you can’t wait, or would rather build something very similar, check out [Brad]‘s original Instructable article!
