Hackaday alum [Todd] has been searching for an old PONG clone for the last two years. This variant is called, “The Name of the Game”. [Todd] has fond memories of playing this game with his sister when they were young. Unfortunately, being the hacker that he is, [Todd] tore the game apart when he was just 14 to build his own Commodore 64 peripherals. He’s been wanting to make it up to his sister ever since, and he finally found a copy of this game to give to his sister last Christmas.
After opening up the box, [Todd] quickly noticed something strange with the power connector. It looked a bit charred and was wiggling inside of the enclosure. This is indicative of a bad solder joint. [Todd] decided he’d better open it up and have a look before applying power to the device.
It was a good thing he did, because the power connector was barely connected at all. A simple soldering job fixed the problem. While the case was still opened, [Todd] did some sleuthing and noticed that someone else had likely made repairs to several other solder joints. He also looked for any possible short circuits, but everything else looked fine. The system ended up working perfectly the first time it was started.
The end of the video shows that even after all this time, simple games like this can still capture our attention and be fun to play for hours at a time. [Todd] is working on part 2 of this series, where he’ll do a much more in-depth review of the system. You can watch part 1 below. Continue reading “Repairing and Reviewing a 1976 PONG Clone”
What is there to do in America while you’re waiting to cross the street at an intersection? Nothing; listen to that impatient clicking sound, and if you live in a busy city, pray you don’t get plowed into. In Germany however, pedestrians will now get to play Pong with the person on the other side.That’s right, as a means to encourage people to just hang in there and wait out the cycle instead of darting across against the light, design students [Sandro Engel] and [Holger Michel] came up with an entertaining incentive involving a potential conversation sparking duel with your impromptu counterpart across the street.
The first of these interactive cross-walk indicators was installed recently in Hildesheim, Germany, two years after the duo first designed them back in 2012. There was a little friction about installing the touch screen equipped modules initially, but after a proper redesign for functionality taking traffic science into account, the city authorities caved and allowed them to test the wings of their progressive idea on one city intersection so far. The mindset behind the invention of these indicators is part of a larger movement to make public spaces safer through means of fun and entertainment. Instead of threatening to punish those partaking in unsafe activity with fines, the notion is to positively enforce following rules by adding a level of play. While pedestrians have the right to walk, the screen shows how much time is left to make their away across, and for the duration that traffic is rolling through, the score will be kept for an individual game of pong for those on either side of the light.
Since the idea is generating some interest, the group of developers involved with the project have moved to promote their work (now branded as Actiwait) with an Indiegogo campaign. They hope to turn their invention into a full fledged product that will potentially be seen all over the world. Admittedly, it’d be charming to see this sort of technology transform our urban or residential environments with a touch of something that promotes friendly social interaction. Hopefully my faith in our worthiness to have nice things is warranted and we start seeing these here in America too. Nice work!
Check out this encounter with the street indicator here. The guy introducing the invention loses to the girl on the other side, but they share a high-five as they pass in the street:

[Jason] is back at it again with another new twist on the technically sophisticated and advanced game of Pong. Fashioned in a ‘Chuck E. Cheese’ style platform, the two players stand side by side each other with large foam hammers. A wack sends the 32 bit ARM powered dot skyward and then back down to the other player, where another wack will send the dot back whence it came. A brightly lit scoreboard keeps track of how many dots slip by.
[Jason] is a veteran of pong inspired games, but putting the HammerPong game together brought with it some new challenges. After being unable to squeeze a few MDF panels into his car, and fighting off flies, yard debris and pet dander that were trying to attach themselves to his freshly painted artwork, [Jason] managed to get his project completed.
The HammerPong is powered by an Arduino Due that controls six WS2812 LED strips and runs the background code. Various latches, shift registers and power transistors control the lights and scoreboard. Be sure to check out the linked project for more detail, and take a look at the video demonstration after the break.

Think the original Pong is cool? How about point to point Pong? [v8ltd] did it in three months, soldering all the leads directly to the chip pins. No sockets required. It’s insane, awesome, a masterpiece of craftsmanship, and surprising it works.
[Jeremy Cook] is building a servo-powered light graffiti thing and needed a laser diode. How do you control a laser pointer with a microcontroller? Here’s how. They’re finicky little buggers, but if you get the three-pack from Amazon like [Jeremy] did, you get three chances to get it right.
NFC tags in everything! [Becky] at Adafruit is putting them in everything. Inside 3D printed rings, glued onto rings, and something really clever: glued to your thumbnail with nail polish. Now you can unlock your phone with your thumb instead of your index finger.
Photographs capture still frames, but wouldn’t it be great if a camera could capture moving images? No, we’re not talking about video because this is the Internet where every possible emotion, reaction, and situation can be expressed with an animated GIF. Meet OTTO, the camera that captures animated GIFs! It’s powered by the Raspberry Pi compute module, so that’s interesting.
[Nate] was getting tired of end mills rolling around his bench. That’s a bad thing. He came up with a solution, though: Mill a piece of plywood into a tray to hold end mills.
The Da Vinci printer, a printer that only costs $500 because they’re banking on the Gillette model, has been cracked wide open by resetting the DRM, getting rid of the proprietary host software, and unbricking the device. Now there’s a concerted effort to develop custom firmware for the Da Vinci printer. It’s extraordinarily bare bones right now, but the pins on the microcontroller are mapped, and RepRap firmwares are extremely modular.
For [Eric]’s entry for our Fubarino Contest, he went down to very low-level hardware and created Pong on an FPGA.
[Eric] used a Basys 2 FPGA board to create this virtual, logic gate version of Pong. Output is via the VGA port, multiplayer and an AI player is implemented, and all the required mechanics for Pong – collision detection, button and switch input, and score keeping are also in this project.
The Fubarino contest requires an easter egg, of course, so when the score for the left player reaches 13 and the score for the right player reaches 37 (get it? 1337?), the previously square ball turns into an extremely pixeley version of the Hackaday logo. The Hackaday URL is also displayed, thanks to [Eric]’s FP(V)GA module for displaying text on his FPGA board.
The improved Pong ball and URL only appears when the scores are 13-37, making this an extremely well-hidden easter egg. Video of [Eric] demoing his Pong below.
This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!

[Pong] has joined an elite club of people who have designed and built their own computer – including a CPU created from discrete 7400 series logic. His computer is the Almost Simple As Possible Computer 3 (ASAP-3). ASAP-3 is not a completely new design. The architecture is based upon the SAP series of computers from Albert Malvino’s book, Digital Computer Electronics. [Pong] looked at quite a few of the “modern retro” computers such as Magic-1, Big Mess o’ Wires 1, and the Duo. These computers were beyond his skill levels back then, so he began to build his own system. His primary design goal was to be able to run a 4 function calculator program.
One thing that can’t be stressed enough is the fact that [Pong] made his design work much easier by using lots of simulation. His tool of choice was Proteus Design Suite. While simulation can’t solve every problem, it can often help in verifying that a given design is sound. The ASAP-3’s instruction set is microcode, based upon the 8085 series instruction set. The microcode itself is stored on Flash ROMS. Using microcode makes ASAP-3 very flexible. Don’t have a machine instruction you need? No problem – just write one up. When all was said and done, [Pong] had over 100 instructions spread over 3 Flash ROM chips.
The hardware was only half the battle – [Pong] found writing the software just as challenging. He wrote all the software by hand in his own machine code. This is where the simulation mentioned above really saved him some time. Even with simulation he still ran into some problems. The ASAP-1 is limited to a clock speed of around 500kHz. Above that, glitches from the ROM chips start triggering the asynchronous inputs in some of the registers. [Pong] doesn’t have a logic analyzer on hand, so he wasn’t able to track this one down further. He also found a (update simulation only) issue with the carry bit on the 74LS181 bit slice ALU. In certain circumstances the carry bit would not propagate correctly. [Pong] corrected this by using a ROM as a look up table replacement for certain ‘181 functions. Even with these limitations, this is still a great hack!

Let’s start off with some lock picking. Can you be prosecuted if it was your bird that broke into something? Here’s video of a Cockatoo breaking into a puzzle box as part of an Oxford University study. [Thanks Ferdinand via Endandit]
[Augybendogy] needed a vacuum pump. He headed off to his local TechShop and machined a fitting for his air compressor. It uses the Venturi Effect to generate a vacuum.
Build your own Arduino cluster using this shield designed by [Bertus Kruger]. Each shield has its own ATmega328. Many can be stacked on top of an Arduino board, using I2C for communications.
[Bunnie Huang] has been publishing articles a few articles on Medium called “Exit Reviews”. As a treasured piece of personal electronics is retired he pulls it apart to see what kind of abuse it stood up to over its life. We found his recent article on his Galaxy S II quite interesting. There’s chips in the glass, scuffs on the bezel, cracks on the case, and pervasive gunk on the internals.
We’d love to see how this this paper airplane folder and launcher is put together. If you know of a post that shares more details please let us know.
Squeezing the most out of a tiny microcontroller was a challenge. But [Jacques] reports that he managed to get a PIC 10F322 to play a game of Pong (translated). It even generates an NTSC composite video signal! Watch the demo video here.
