Hi Nathan, hi Ralph, (...) actually for the adventurous hardware hacker it might be possible to revive it using the ERASE pin. Though in this case, and if you are sure you didn't run the script for setting the security bit, I'd ask LEGO for a (...) (18 years ago, 4-Feb-07, to lugnet.robotics)

(...) I now have one high power TX brick, which works very well now that I've fitted it with a not quite central muzzle. This means that IR can still get in and out (somewhat), but it is very concentrated IR! Long range + Muzzle works accurately (...) (18 years ago, 4-Feb-07, to lugnet.robotics)

Now, before you all laugh about this, I'm actually very serious. I don't know how many of you have ever played Laser Tag before, but basically you have a laser enabled gun that fires infrared light at other people. Completely harmless. How I got (...) (18 years ago, 4-Feb-07, to lugnet.robotics)

(...) It may be obvious, but: Holding the reset pin for a few seconds simply does a brick reset. Holding the reset pin for around 15 seconds is supposed to put the brick into SAMBA mode. You are doing the second I hope. And just to be safe, you've (...) (18 years ago, 4-Feb-07, to lugnet.robotics, lugnet.robotics.nxt)

(...) Nathan, What software did you use to load V1.04? It sounds like there is something in there that set the firmware to read-only after it loaded it. Can you find any settings like that in that software? Steve (18 years ago, 4-Feb-07, to lugnet.robotics, lugnet.robotics.nxt)

All, Up until this point, I kept hearing that it was pretty much next to impossible to "brick" a brick. However, I think I've managed to be the first person to prove that it *can* be done (not that I'm proud of this fact :-( ). A few weeks back, I (...)
