The Chaos Communication Congress is growing! Actually, it’s not, but there may be an ‘overflow venue’ for everyone who didn’t get a ticket. There’s a slack up for people who didn’t get a ticket to 33C3 but would still like to rent a venue, set up some tables, stream some videos, and generally have a good time.
Need to test a lot of batteries? Have one of those magnetic parts tray/dish things sitting around? This is freakin’ brilliant. Put your batteries vertically in a metal dish, clip one lead of a meter to the dish and probe each battery with the other lead of your meter.
Pravda reports the USS Zumwalt and HMS Duncan – the most technologically advanced ships in the US and Royal Navies – have turned into, ‘useless tin cans due to China’, with ‘Microchips made in China putting the vessels out of action’. Again, Pravda reports this, so don’t worry. In other news, someone found a few USB drives in a parking lot in Norfolk, Virginia.
Here’s how discourse goes on the Internet. Someone does something. Everyone says it’s stupid. We wait a few days or weeks. Someone posts something on Medium telling everyone it’s actually okay. Public opinion is muddled until the actual issue being discussed is rendered technologically irrelevant. For the newest MacBook Pro, we’re currently at stage 3 and ‘it’s kind of great for hackers’. Now if only we knew how to make USB-C ports work with microcontrollers…
If you have a Prusa i3, here’s a free gift: a Spitfire. The files to print a remote control, 973mm Spitfire Mk XVI are now free for Prusa i3 and i3 Mk 2 owners. Why? Because it’s cool, duh, and [Stephan Dokupil] and [Patrik Svida], the guys behind the Spitfire and other 3D printed RC planes, are also in Czech. Now all we need are Czech roundel stickers.
Ever see a standard server rack stuffed full with 8-dozen MacBook Pros? Well now you have.
Now before the torrential downpour of anti-Mac comments come, this actually has a purpose. No seriously. Besides, what company in their right mind would spend that much money on a rack full of paperweights? Kidding.
[Steve] works for a company that designs electronics, and for a particular launch they needed to perform a lot of testing — using MacBook Pros. There are ways he could have emulated OS X on a much cheaper hardware setup, but the whole point was to test the product with Apple hardware. So he took a stroll down to the local Apple store and picked up two pallets worth. Continue reading “96 MacBook Pros: Most Expensive Server Rack We’ve Ever Seen”
[Sterling]’s MacBook Pro has a propensity to heat up at times. Some of this overheating is due to to what he uses his Mac for – gaming and making music. A larger part of this overheating is that this laptop is a consumer electronics device – it’s going to die sooner or later. One day in March, this laptop bit the bullet, and that’s where this story gets interesting.
Before the MacBook died, [Sterling] was logging temps between 80 and 90ºC, with a maximum of 102º. The simple fixes, compressed air, a laptop stand, and running the fans full blast all the time didn’t help. When the laptop died, [Sterling] was pretty sure some solder joints came loose. Sending the logic board off to a place that specializes in reflowing would take weeks. A more drastic plan of attack was necessary.
[Sterling] disconnected all the wires, connectors, and heat sinks and preheated his oven to 340º F. The logic board was placed on a cookie tray and stuffed into the oven for seven long minutes. Thermal paste was reapplied, heat sinks reinstalled, connectors connected, and the machine booted. It worked great for about eight months with temperatures averaging around 60 or 70º C.
Two weeks ago, the laptop died again. This time it was reflowed with a heat gun and ran for about an hour. The third attempt was the cookie sheet again, only this time [Sterling] added something. Speed holes. Or vents, or whatever else you want to call them.
Now there’s a noticeably increased airflow in the Mac, much better than before. Average temps are back down to 40 or 50º C, lower than they were with just a reflow. The jury is still out if this new addition can go the distance, but with any luck, this mod might make it through 2015.
Thanks [Doug] for the tip.
[Adrian] came across a treasure trove of 507 mechanical device designs. It didn’t seem quite right for a Retrotechtacular post, but we wanted to share it as it’s a great place to come up with ideas for your next Rube Goldberg machine.
Biking with headphones is dangerous. That’s why [J.R.] built a handlebar enclosure for his Jambox Bluetooth speaker.
While dumpster diving [Mike] found a Macbook pro. It was missing a few things, like a keyboard, touchpad, battery, ram, and storage. He borrowed a power supply to test it out but without the keyboard there’s no power button. He figured out the traces on the motherboard which turn it on when shorted.
[Mateusz] want to let us know about the Hercules LaunchPad. Like the other TI Launchpad offerings it’s an all-in-one dev board. The Hercules line features a couple of flavors of dual-core ARM chips. Can you believe the dev boards you can get for under $20 these days?
After seeing the ammo can sound system about a month ago [Ilpo] was inspired to share his ammo can PC case with us.
And finally, here’s a way to display your Bitcoin mining rig for all to see. This system was laid out in an antique frame and hung on the wall.
If you’ve seen one of the fancy, expensive MacBook Pro laptops with a Retina display, you’ll know how awesome having that much resolution actually is. This incredible resolution comes with a price, though: the MBP with a Retina display is about $500 more expensive than the normal resolution MPB model, and it’s very difficult to find a laptop of comparable resolution without cries of fanboyism being heard.
[Daniel] over at Rozsnyo came up with a neat solution that connects one of these fancy 15-inch Retina displays to just about any computer. The build is the beginning of a product that works just like the previous DisplayPort adapter for the iPad retina display, but with the possibility of a few added features such as HDMI input and use of the internal webcam and WiFi antennas.
This build isn’t really a finished product anyone can buy and plug into a replacement Retina display just yet. Even if it were, it’s extraordinarily difficult to find a replacement display for the high-end MacBook for under the price of a really good monitor, anyway. In a few years, though, when the old, busted Retina laptops are traded up for a new, shiny model, though, we’ll be the first to try out this mod and get some serious desktop space.
