So I have two of these things at work and they go unused as the default firmware is somewhat lacking in features.<\/p>\n

This made me wonder what the hardware looks like inside them. This is quite possibly one of the hardest pieces of hardware I’ve ever tried to open. The case isn’t sensible at all, but it seems if you can get the blue front section to decouple from the rest of it, it slides apart easily.<\/p>\n

There’s one Samsung chip in the center that didn’t scan very well so here is what was written on that one:<\/p>\n

I think the conclusion we can come to here is that there is far too little flash and RAM to fit something like DD-WRT. I wonder what other projects might fit into these constraints?<\/p>\n","protected":false},"excerpt":{"rendered":"
