Underwater ROV

[SpaceShipOne] has built this very nice looking under water ROV.  It is still a work in progress, but nearly complete.  This ROV is a fairly simple construction. most of the body parts are held together using zip ties.  There’s no microcontroller and no custom boards.  He’s using a radio control transceiver that was intended for airplanes to control some standard speed controllers and servos.  For thrust, he pulled the motors out of some bilge pumps and fitted them with propellers.  He’s only tested it once, but promises videos from the lake soon.  He mentions [Jason Rollette] several times since [Jason] has done both simple and complex designs in the past.

PS3 ECC algorithm reversed

The ECC is the protection that keeps the PS3 from booting with a custom flashed rom. These folks managed to reverse the code. This means that they can now generate custom ones to allow the rom to boot.  They haven’t gotten very far with that side of it yet, but they did manage to rescue a broken PS3 with it.  They had one that had a bad flash, they were able to re write the code in it and it booted right up.
