How The Sony PlayStation Was Hacked

November 5, 2018 by 34 Comments

Playgrounds were the comment sections of their day. Every weekday from exactly 1:17 PM until 1:43 PM there were swings to be swung, rumors to be spread, and debates to be settled by whomever was the loudest (some things never change). Allegiances were formed and battle lines were drawn based solely on what video game console you supported. It was this playground system that perpetuated the urban myths of the time.

For PlayStation fans there was the myth that you could save Aerith from her fate in Final Fantasy VII if you just cast the right spell, or the secret code in Tomb Raider that would let you see all of Lara Croft. There was the myth that no one could possibly copy a PlayStation game because all the bottoms of the discs were black. Even the very existence of the first PlayStation, the Super Nintendo PlayStation prototype, was an urban legend. The difference was that last one turned out to be true.

Let’s jump in and take a look at the cat and mouse game between modchip makers looking to defeat the original PlayStation’s copy protection, and Sony’s efforts to protect their castle.

Arachnid Ale Uses Yeast To Make Spider Silk

November 5, 2018 by 21 Comments

Many people who read Hackaday hold the title of “Webmaster” but [The Thought Emporium] is after slightly different credentials with the same title. He aims to modify a strain of yeast to produce spider silk. Charlotte’s Web didn’t go into great detail about the different types of silk that a spider can produce, but the video and screencap after the break give a rundown of how spiders make different types of silk, and that each species of spider makes a unique silk. For this experiment, the desired silk is “beta sheets” which the video explains are hard and strong.

Some of the points mentioned in the video rely on things previously mentioned in other videos, but if you are the type of person excited by genetic modifications or using modified yeast to produce something made by another lifeform, you will probably be just fine. This is one of the most technical videos made by [The Thought Emporium] as he goes into the mechanisms of the modifications he will be making to the yeast. It sounds like a lot of work and the financial benefit of being able to produce spider silk affordably could be great, but in true hacker form, the procedure and results will be made freely available.

For some background into this hacker’s mind, check out how he has hacked his own lactose intolerance and even produced graphene through electrochemical exfoliation.

Pint-sized Jacob’s Ladder Packs 10,000 Volts In A Pickle Jar

November 5, 2018 by 12 Comments

File this one away for your mad scientist costume next Halloween: [bitluni]’s Pocket Jacob’s Ladder is the perfect high voltage accessory for those folks with five dollars in parts, a 3D printer, and very big pockets.

[bitluni]’s video shows you all the parts you’ll need and guides you through the very simple build process. For parts, you’ll require a cheap and readily-available high-voltage transformer, a battery holder, some silver wire for the conductors, and a few other minor bits like solder and a power switch.

Once the electronics are soldered together, they’re stuffed inside a 3d printed case that [bitluni] designed with FreeCAD. The FreeCAD and STL files are all available on Thingiverse. We’re not sure what type of jar [bitluni] used to enclose the electrodes. If your jar isn’t a match, you’ll have to get familiar with FreeCAD or start from scratch with your favorite CAD package.

Either way, we enjoy the slight nod toward electrical safety and the reuse of household objects for project enclosures.

If you’re interested in a Jacob’s Ladder with significantly higher voltage we’ve got you covered, or we’ve also written about another tiny portable Jacob’s Ladder.

The full video is embedded after the break.
