[Colin Alston] was able to snag a handful of Mini ITX motherboards for cheap and built a mini super computer he calls TinyJaguar. Named partly after the AMD Sempron 2650 APU, the TinyJaguar boasts four, yes that’s four MSI AM1I Mini-ITX motherboards, each with 4GB of DDR memory.
A Raspberry Pi with custom software manages the cluster, and along with some TTL and relays, controls the power to the four nodes. The mini super computer resides in a custom acrylic case held together by an array of 3D printed parts and fasteners.There’s even a rack-like faceplate near the bottom to host the RPi, an Ethernet switch, an array of status LEDs, and the two buttons.
With 16 total cores of computing power (including GPU), the TinyJaguar is quite capable of doing some pretty cool stuff such as running Jupyter notebook with IPyParallel. [Colin] ran into some issues getting the GPU to behave with PyOpenCL. It took a bit of pain and time, but in the end he was able to get the GPUs up, and wrote a small message passing program to show two of the cores were up and working together.
Be sure to check out [Colin’s] super computer project page, specifically the ten project logs that walk through everything that went into this build. He also posted his code if you want to take a look under the hood.
Did you ever commit any pranks in your time at high school, college, or university? Maybe you moss-painted a rude word on the wall somewhere, or put a design in a sports field with herbicide, or even worse, slow-release fertiliser. [Roman Kozak] and his friends went far further than that last summer when they replicated some of the most famous student pranks; they put a Jaguar S type car on the roof of their school. And now the dust has settled, he’s posted an account of how they did it.
Of course, putting a car on the roof is a significant challenge, particularly when you only have the resources of a high-school student. Ensuring the roof was strong enough for a car, and then hiring a crane to do the deed, was beyond them. They therefore decided to take the wheels and outer body panels of a car and mount them on a wooden frame to give the appearance of a car.
They needed a statement vehicle and they didn’t have a huge budget, so it took them a while to spot a for-parts Jaguar S type which when it came into their possession they found only had a fault with its reverse gear. Some hard work removed the panels, and the rest of the car was taken for scrap.
Frenetic work as the term end approached gave them their frame, and a daring midnight raid was mounted to winch the parts to the roof with a pulley. The result was so popular with their classmates and teachers that they owned up to the prank rather than preserve their anonymity. We think these young scamps will go far.
This is definitely the first car-on-roof prank we’ve brought you on Hackaday, but it’s not the first to be done. [Roman] and his friends cited an MIT prank as their inspiration, but the daddy of car-on-roof stunts has to go to Cambridge University students in the 1950s. Their Austin might be a lot smaller than the MIT Chevy or [Roman]’s Jag, but they got it onto their roof in one piece as a full car rather than a facsimile of one.
Important note: The author would like to state for the record that she and her friends were somewhere else entirely and had solid alibis when in summer 1993 the logo of Hull University Union Technical Committee appeared in the lawn outside Hull University Union. We’re sure that commenters will be anxious to set their own records straight for posterity in a similar manner.
You’d figure a luxury car like a Jaguar would have a high-end infotainment system. [RichTatham]’s Jag did, but the trouble was that it was a high-end system when a cassette deck and trunk-mounted CD changer were big deals. So naturally, he saw this as a great reason to modernize the system by grafting a netbook into the Jag’s dash. The results are fantastic!
Even though the Jag’s original system didn’t have much left that made it into the final project — the navigation system, CD changer, phone and even the amps ended up on the scrap heap — at least the dashboard instrument cluster proved to be very amenable to his mods. By substituting a climate control cluster from another model into his car, he was able to free up tons of space for the netbook’s 8″ display. A custom bezel and some clever brackets completed the head-end of the new system, and the look is as close to a factory install as you’re likely to find in an aftermarket mod. With the netbook stashed in the bay vacated by the OEM system, a GPS dongle, and a USB sound card connected to a 5.1 amp using the original speakers this jag is ready to bump. We bet that the system sounds as good as it looks, and with the added functionality of a Windows PC to boot.
For obvious reasons, lots of computers make it into hackers’ dashboards, whether they be Windows like this one, Samsung tablets or Nexus tablets running Android, and even phones. But [Rich]’s build is top notch, and takes in-car integrations to the next level.
Released in 1993, the Atari Jaguar suffered from a number of problems – it was difficult to program, had hardware idiosyncrasies, and with the CD drive was vastly overpriced compared to the Sega Saturn and Sony Playstation released one year later. Nevertheless, the Jaguar still has a rabid fanbase that counts [10p6] among them, and he’s created what Atari should have released 20 years ago.
In a few forum threads at jaguarsector (login required) and nexgam.de (no login, German), [10p6] goes over his changes to the classic Jaguar + CD combo. He’s stuffed everything inside a new case, cutting down on the amount of plastic from the old enclosure. A proper integrated power supply has been added, replacing the two power supplies used in the original. It’s also overclocked to 32 MHz, compared to the 26 MHz of the stock unit, making this a very powerful system that could have easily competed with the Saturn and Playstation.
[10p6] has an amazing piece of hardware on his hands here, and should he ever want to make a few molds of his new Jaguar, he could put together some sort of kit to replicate this build. He’s still working on finding a model maker and perfecting his case design, but a new, improved version of the Jaguar is something we’d love to see in a limited production.
We don’t know why, but the Atari Jaguar is getting a lot of attention this week. [10P6] just came up with this Jaguar/CD combo that reminds us what Atari could have come up with in 1993.
The build itself is relatively simple once you get past [kevincal]’s ‘April Fools’ type joke he played on the Atari Age forum. [10P6] took a regular Jaguar CD drive and cut a hole into a Jaguar case. The whole case mod took less than a three hours, but [10P6] gives us a lot of commentary into what Atari could and/or should have built in 1993.
[10P6] suggests this type of Jaguar would have saved Atari money if the CD drive was stock on the base unit and released at a slightly increased price. This would cut out the cost of the cart slots and reduced the amount of plastic in manufacturing. [10P6] also talks about how Atari engineers could have dropped the 68000 coprocessor with an increase in the system clock. We’re not quite fond of that idea (ask us about our tattoo), but the logic does make sense.
Of course, this build comes on the heels of the Jaguar Portable we saw a few days ago. Honestly, we have no idea what’s going on with the Jaguar build.
