In a previous weblog posting, I mentioned that I had bought a Linksys NSLU2 NAS (networked attached storage) device that I was hacking away on. I recently dusted it off and started playing with it again, after installing the unslung firmware that lets you run linux on it. What was curious was that I had mentioned previously that the slug (as they are affectionately called) was a 266mhz ARM processor. But I found out recently that Linksys included jumpers to effectively run the processor at half speed.
But you can fix that by snipping out a surface mount resistor (I just cut it out with an exacto knife). Total mod time: approximately two minutes (once I read the page on how to open the case). Net result: double speed NSLU2.
The Nintendo DS is kind of a cute little gadget, and what's cool is that someone is already doing all the heavy lifting of getting TCP/IP to work on its wireless. This uses Adam Dunkel's lwip implementation. Not quite done yet, but interesting!
