Teardown: Sony’s New Aibo Goes Under The Knife

October 22, 2018 by Drew Littrell 22 Comments

In a complete surprise, Sony has moved to release the latest version of their robotic dog series, Aibo, in North America. The device is already out in Japan, where there are a number of owner’s clubs that would rival any dedicated kennel club. Thanks to the [Robot Start] team, we now have a glimpse of what goes into making the robotic equivalent of man’s best friend in their teardown of an Aibo ERS-1000.

According to Yoshihiro of Robot Start, Aibo looks to be using a proprietary battery reminiscent of the Handycam camcorders. Those three gold contacts are used for charging on the rug shaped power base that Aibo will periodically return to in order to take a”nap”. There are a couple of square OLED screens behind those puppy dog eyes. They are full-color OLEDs somewhere in the one-inch ballpark. Between the screens is a capacitive touch sensor that wraps around to the top of the head that are also pressure sensitive.

According to Sony’s press release, the fish-eye camera housed in Aibo’s snout is used to identify faces as well as navigating spaces.

Laying out all the major parts out together certainly drives home the complexity of the latest Aibo. It’ll be interesting to see the progression of this device as all of them come equipped with 4G LTE and 802.11 b/g/n WiFi that connect to Sony’s servers for deep learning.

New behaviors are supposed to download automatically as long as the device is under the subscription plan. While Sony has no current plans to integrate with any voice-activated virtual assistant, we can still look forward to the possibility of some expanded functionality from the Hackaday community.

For the rest of the teardown photos make sure to head over to [Yoshihiro]’s write up on Robot Start. Also just in case anybody cared to see what happens when the first generation Aibo ERS-111 from 1999 meets the 2018 Aibo ERS-1000, you’ll find the answer in the video below:

Mike Tyson’s Punchout Patch Gives HDTV Lag A K.O.

October 12, 2018 by Drew Littrell 12 Comments

They just don’t make them like they used to. Digital televisions have rendered so many of the videogames designed in the days where CRTs ruled the earth virtually unplayable due to display lag. Games that were already difficult thanks to tight reaction time windows can become rage inducing experiences when button presses don’t reflect what’s happening onscreen. A game that would fall into the aforementioned category is Mike Tyson’s Punchout for the NES. However, NES homebrew developer [nesdoug] created a patch for the 31 year old classic that seeks to give players playing on modern displays a fighting chance.

The lag fix patch for Mike Tyson’s Punchout seeks to alleviate some of the display lag inherent in digital displays by adjusting the gameplay speed. Some of the early stages aren’t altered very much, but the later fights incur more significant slowdown to compensate for modern display lag. It’s evident that [nesdoug] is a longtime fan of the game as he also uploaded a remix patch that mixes up the stages and color palettes.

The patch itself comes in the form of an IPS file. To apply the lag fix patch you’ll need an IPS patching tool, like Lunar IPS, along with your own personal backup ROM of Mike Tyson’s Punchout. A checksum value is provided on the lag fix patch download site to ensure you have a usable ROM file. Do note that the ROM file is overwritten in the process of applying the patch, so make sure to put the original file in a safe place. After patching is complete the fun can be had using your favorite NES emulator, or using a flashcart if you’re seeking to play on original hardware.

If you’re looking to dump your own NES cartridges without the plug and play convenience of devices like the Retrode, there is a tutorial in the video below the break:

Atari Lynx Becomes Modern 2600 Console Homage

October 10, 2018 by Drew Littrell 5 Comments

With its introduction in 1989, the Atari Lynx was the first handheld videogame system to include a color LCD. The gigantic size and equally gigantic price tag did not win-over a massive audience, but that doesn’t mean the Lynx was without its fans. Over the past few months a modder named [Jared] has been toiling away with his project to transform an Atari Lynx into a home console.

The inspiration behind the mod was the original Atari console, the Atari 2600. [Jared’s] console mod, called the Atari Lynx 2600, utilizes a four-switch 2600 case as an enclosure. However, since the Atari 2600 joystick did not offer enough button real estate an NES controller was used instead. A male-male serial cable serves as the new controller cord, while all the buttons on the face of the Lynx are hardwired to a female DB9 port. As an added touch a custom 3D printed cartridge adapter was incorporated into the original 2600 cartridge slot.

Since the Lynx did not natively support video out, and intermediary device known as the McWill LCD mod kit was used. The McWill LCD mod is typically done in order to modernize the Atari Lynx’s screen with hardware from this decade, but [Jared] used the kit in order to get VGA video output from the Lynx. Not satisfied with just VGA [Jared] also included a VGA to HDMI scaler inside to ensure a wider compatibility with current displays. Fittingly the HDMI port was placed on the back of the 2600 enclosure where the RF video used to come from.

Bonus points should go to [Jared] for going the extra mile and creating a custom console box to accompany the console mod. The entirety of the project was detailed in a three-part video series, but you can watch the console in action in part 2 below:

Putting The Sega Teradrive Into Overdrive

October 9, 2018 by Drew Littrell 25 Comments

During the 80s and 90s it seemed like Japan got all the good stuff when it came to videogames. In the US there were consoles called the NES, the TurboGrafx-16, and the Genesis. While in Japan they had cooler names like: the Famicom, the PC Engine, and the Mega Drive. The latter was incorporated into a plethora of different form factors, including the little known IBM PC/Mega Drive combo known as the Sega Teradrive. Finding a rare Japanese 1990s PC stateside is a feat in and of itself, and thanks to an electronics hobbyist named [Ronnie] there is at least one Teradrive out there still running strong thanks to an upgraded CPU mod.

In theory, the Sega Teradrive was a dream-machine; combining the utility of an IBM PC with the fun of a Sega Mega Drive. The dual functionality extended to the video modes where both VGA and composite video were supported. However, the reality was that the final design was less than desirable. The Teradrive shipped in 1991 with an Intel 80286, 16-bit processor which was already two processor generations behind at the time. The meager 10Mhz clock speed was on the lower end of the performance spectrum which meant that many DOS titles ran poorly…or not at all.

Not satisfied with those specs, [Ronnie] modded his Teradrive with an adapter board containing an Intel 80486 processor clocked at 66Mhz. The upgrade, accompanied with a complete re-cap of the motherboard, brings the IBM PC to 486DX status. This opened up a few new possibilities including the Thundercats Demo in the video below:

Doom Battle Royale Mod With 64 Players Hurts Plenty

October 4, 2018 by Drew Littrell 14 Comments

Sixty-four players are dropped into a map, but there can be only one that emerges victorious…heard that before, right? Thanks to PC Game modder [Bambamalicious] there is yet another entrant into the rapidly growing videogame genre. The difference this time, however, is that their 64 player DooM Royale (with cheese) mod is ready to show all those other also-ran games how the granddaddy of FPS games does it.

According to the announcement post the mod is “…a 64 player Battle Royale using Doom 2 as the IWAD, and the Zandronum engine as it’s base. The speed of gameplay will be unchanged from normal Doom, and when you die, that’s not the end for you!”. There is a respawn system, but each player is given a limited number of lives. To ensure no server feels like a ghost town [Bambamalicious] included bots that will spawn in matches with low participation. Each game inevitably results in a “last man standing” face off that has the victor coming away with the coveted “Royale with cheese”. Other than the aforementioned changes, this is still the seminal classic Doom (1993).

Do note that in order to play the mod, the Zandronum engine is a required in order to take part in the fun. The engine is the backbone that allows for leaderboards as well as hopping between custom servers. Zandronum additionally supports many other multiplayer match types for instance: Team Deathmatch, Capture the Flag, Possession, and Skulltag. Up to 64 players are supported in those match types as well.

From the looks of the DooM Royale (with cheese) map, there should be frequent enemy player encounters and no respite for those seeking to just “hide in a bathtub”. The multiple levels should supply plenty of opportunity to take advantage by attacking from above. Test footage of the mod in action can be seen in the video below.

VinylVideo Is Literally Video On Vinyl

October 1, 2018 by Drew Littrell 25 Comments

It’s often said that the music etched into a vinyl record takes on a transcendent quality that you simply can’t find in a digital recording, but does that still apply when you add motion picture? The collaboration of [Sengmüller and Diamant] sure think so, because they are offering a new experience for the turntable with the introduction of their VinylVideo pre-amplifier. No tape reels here, this project shows the extend of what is possible through analog video.

While all record players capable of playing back 7 in. 45 RPM are compatible with the system, the VinylVideo records themselves specially cut in order to generate the video signal. Each of the custom records has room for a 4-minute music video on the A-side, and the single on the B-side. Videos play back in black & white, sub-standard definition with mono audio, and run around 12 frames per second. The pre-amp takes in the analog signal from regular audio cables via RCA jacks or 3.5mm headphone jack, and then a Raspberry Pi model A+ handles the analog-to-digital conversion. Video out options include HDMI and composite video via a 3.5mm TRSS jack.

The current VinylVideo pre-amp is actually a refinement of the original project from the mid ’90s where it was a part of folk art exhibits. The legacy website (circa 1999) is still live, so you can give it a visit. However, for the most authentic experience you may want to fire-up a virtual machine with Netscape Navigator and Real Player installed.

For a more in-depth look at the VinylVideo in action there is a great video below from [Techmoan]:

Remember When Blockbuster Video Tried Burning Game Cartridges On Demand?

October 1, 2018 by Drew Littrell 31 Comments

By the onset of the 1990s one thing was clear, the future was digital. Analog format sales for music were down, CD sales were up; and it was evident, at least in the US, that people were bringing more computing devices into their homes. At the beginning of the decade, roughly 1 in 3 American households had a Nintendo Entertainment System in them, according to this Good Morning America segment.

With all those consoles out there, every shopping season became a contest of “who could wait in line the longest” to pickup the newest titles. This left last minute shoppers resorting to taking a rain check or return home empty handed. Things didn’t have to be this way. The digital world had emerged and physical media just needed to catch up. It would take an unlikely alliance of two disparate companies for others to open their minds.
