> No doubt if it gets popular the manufacturers will start looking the bootloader though

The bootloader is already "locked" - you have to send a special sequence to unlock it.

As the article says:

So the functionality has to be there - they can't take it away. They could perhaps start changing the sequence required to enable loading mode, but what would be the benefit to them? It wouldn't increase their profits, and they have no reason to care about a few people hacking SD cards to do more than store stuff. Maybe, if the dodgy/oversized cards being sold are negatively affecting a particular brand's reputation, they might insist on their chip producers doing something... *shrug*

Locled/secured, whatever. Given the potential for malicious use, it could well be in the manufacturers interests to stop people messing with them.

According to the video presentation, the potential for malicious use is somewhat limited by the fact that comms control is led by the host, not the SD card itself. bastard by name bastard by nature

I hope these Arduinos get here soon, the light switch came last week and is fitted and waiting to be controlled! ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

I am curious. In what situations will you remotely control your lights? I tried to count the times I wished I didn't have to go over and press a switch on the wall like some sort of schmuck but so far it's none. No times. But I bet people said that about the TV remote, and well, who's a schmuck now? Those potentially-existing people that I bet on, that's who.

Part of buying just one switch is to see how useful it is. Current ideas are switching between "moods" if I'm watching TV or a film. Once I can control the switch(es) via RPi/Arduino I will easily be able to that through XBMC. So, I'd pop the living room lights into my Film mode which might be to turn off the big light and switch on a lamp, or turn everything off all together. Forgetting to turn a light off when you go out and being able to turn it off using your phone. Being able to set timers for your regular lights. If you have suitable bulbs you could even have your bedroom light slowly getting brighter like one of those SAD/Light alarms. No idea whether I'll make use in those ways but they're possibilities. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

I guess at the moment I use little timer plugs for a couple of lamps when we're away on holiday. Maybe I would get right into this! I do also turn a lamp on and a main light off for films! Although usually that's how things already are.

Pah, I didn't watch the video.

Looking at the 'features' section here all bit the write protect notch could be compromised on card.

Well the Arduinos that weren't pre-soldered arrived first. My soldering is pretty bloody shoddy. Annoyingly I thought they had pre-soldered Serial pins but nothing at all was soldered. Hopefully I'll be able to control the switch tonight. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

Nice one! I've been meaning to work on mine but I've felt/been so tired this month. There have been a few days that I've went to bed on Friday night and woke up Sunday morning! I can think of at least two times this month that I've done that. I hope I can get my mojo back soon! --------------------------------------------- Give me liberty or, I dunno, something.
