Oh, boy. You know what’s happening next weekend? The Midwest RepRap Festival. The greatest 3D printing festival on the planet is going down next Friday afternoon until Sunday afternoon in beautiful Goshen, Indiana. Why should you go? Check this one out. To recap from last year, E3D released a new extruder, open source filaments will be a thing, true color filament printing in CMYKW is awesome, and we got the world’s first look at the infinite build volume printer. This year, The Part Daddy, a 20-foot-tall delta bot will be there once again. It’s awesome and you should come.
We launched the 2018 Hackaday Prize this week. Why should you care? Because we’re giving away $200,000 in prizes. There are five challenges: the Open Hardware Design Challenge, Robotics Module, Power Harvesting, Human-Computer Interface, and Musical Instrument Challenge. That last one is something I’m especially interested in for one very specific reason. This is a guitorgan.
Building a computer soon? Buy your SSD now. Someone fell asleep on the e-stop at a Samsung fab, and now 3.5% of global NAND production for March has been lost.
Need to put an Arduino in the cloud? Here’s a shield for that. It’s a shield for SIMCom’s SIM7000-series module, providing LTE for a microcontroller. Why would you ever need this? Because 2G is dead, for various values of ‘dead’. 3G is eventually going to go the same way.
A bridge collapsed in Florida this week. A pedestrian walkway at Florida International University collapsed this week, killing several. The engineering efforts are still underway to determine the cause of the accident, but some guy from Canukistan posted a pair of informative videos discussing I-beams and pre-tensioned concrete. It’s going to be months until the fault (and responsibility) will be determined, but until then we have the best footage yet of this collapse. It’s dash cam footage from a truck that rolled up to the red light just before the collapse. This is one that’s going to go down in engineering history along with the Hyatt Regency collapse.
Need to test your app? Here’s a delta robot designed for phones. You would be shocked at how popular this robot is.
The title might seem a little harsh, but it is a direct quote from the video by [Linus Tech Tips] that you can see below. He picked up a board that is a RAID 0 controller for up to ten SD cards so you can use them as a conventional SATA SSD. Of course, the channel’s tag line is “impractical solutions for improbable problems” but even by his own admission, this is pretty impractical.
It is odd for us to scoff at any kind of hack, but honestly, it is hard to see the value to this, other than it is amusing to think some factory turned these boards out hoping to make a profit. Besides being amusing, though, it is also a good exercise in design trades. For example, when you design a car, you want it to be safe, but you can’t make the body out of four-inch thick steel because of cost, weight, and fuel consumption. So you balance these concerns by making tradeoffs.

The Microsoft Surface Pro 3 is a neat little tablet, and with an i7 processor, a decent-resolution display, and running a full Windows 8.1 Pro, it’s the closest you’re going to get to a desktop in tablet format. Upgrading the Surface Pro 3, on the other hand, is nigh impossible. iFixit destroyed the display in their teardown, as did CNET. [Jorge] wanted to upgrade his Surface Pro 3 with a 1 TB SSD, and where there’s a will there’s a way. In this case, a very precise application of advanced Dremel technology.
Taking a Surface Pro 3 apart the traditional way with heat guns, spudgers, and a vast array of screwdrivers obviously wasn’t going to work. Instead, [Jorge] thought laterally; the mSSD is tucked away behind some plastic that is normally hidden by the small kickstand integrated into the Surface. If [Jorge] could cut a hole in the case to reveal the mSSD, the resulting patch hole would be completely invisible most of the time. And so enters the Dremel.
By taking some teardown pictures of the Surface Pro 3, printing them out to scale, and aligning them to the device he had in his hand, [Jorge] had a very, very good idea of where to make the incision. A Dremel with a carbide bit was brought out to cut into the metal, and after a few nerve-wracking minutes the SSD was exposed.
The only remaining task was to clone the old drive onto the new one, stuff it back in the Surface, and patch everything up. [Jorge] is using some cardboard and foam, but a sticker would do just as well. Remember, this mod is only visible when the Surface kickstand is deployed, so it doesn’t have to look spectacular.
Thanks [fridgefire] and [Neolker] for sending this in.
A while ago [Frank Zhao] built a computer in an aquarium. It’s exactly what you would expect – a bunch of parts stuffed into a container filled with mineral oil. Yes, there’s an i7 and a GTX970 in there, but there’s also a bunch of neopixels and a neat little bubbling treasure chest. That wasn’t enough for [Frank], and he wanted to add a HDD activity monitor. What’s the most absurd activity monitor for an SSD? An old platter-based drive, of course.
The build is relatively simple and something [Frank] put together from spare parts in a day. After cracking open an old PATA hard drive, the voice coil for the hard drive arm was connected to the motherboard’s HDD activity signal through a few MOSFETs. The platter motor is controlled by an MTD6501 motor driver, set to spin up when the circuit is on.
It’s a kludge as far as controlling the components of a hard drive go, but that’s not really the point. It’s just a neat project to show when the SSD in the aquarium computer is being accessed. That said, the activity monitor is currently disconnected because the old HDD is so freakin’ loud. It looks really cool, though.
We missed the original announcement, but Apple unveiled more than just the iPad Mini at their last event. They’ve got a new storage system called Fusion Drive which is supposed to combine the access speeds of solid state with the storage density of platter drives. When you look just under the surface what you’re really seeing is a disc drive with grossly enlarged cache in the form of an SSD drive. How about moving from the 64 MB or so of cache seen on many large hard drives today to something like 64GB?
Well you don’t have to wait for Apple to do it. [Patrick Stein] gave it a shot using command line tools to combine an SSD with a physical drive. Sure, it’s not an all-in-one solution, but it is a pretty good proof. The linchpin that will really make it possible is a low-level driver that can handle the caching on the SDD, while ensuring that the data eventually makes it to the platter for long-term storage.
[Scott] was trying to fix a laptop, and we all know how that sometimes ends. Having a spare 128GB solid state drive and a Dell Mini 10 netbook to shove it in, there was only one problem, the drive did not have SATA connectors. That problem was taken care of like a pro with this FPC to SATA converter.
Inspired by our recent spot about Speeding up a ThinkPad, he was able to find information about the FPC connector from a similar Samsung model, order a SATA connector, FPC zero force connector and matching 24pin jumper. From there a board is designed to connect the two interfaces, taking notes of how other drives have their SATA traces laid out to ensure proper function.
The board is etched and connectors soldered, with every thing plugged in and tested, a little bit of glue is used to hold everything in the stock netbook’s drive sled, resulting in really fast boot times, and a factory look.
[Marek Walther] uses a ThinkPad x41 tablet for business on a daily basis. Since he’s on the go with the device he figures that hardware failure is eventually going to strike and with that in mind he purchased a second unit – slightly broken – to fix as a backup. He had never been excited about the speed of the tablet so he set out to find improvements. One of the options was to replace the traditional hard drive with a solid state model (translated). But simply dropping in an SSD isn’t going to make things faster. That’s because the stock drive uses a PATA interface. After a bit of snooping [Marek] discovered that the motherboard has a SATA interface that has a bridge connecting to the PATA plug. By removing the bridge and soldering a SATA cable to the board he was able to improve performance while increasing storage capacity at the same time.
