I have been using a MikroTik RouterBoard RB750 for a while now, and i love it! Over the weekend, i upgraded it to a RB1100. Its the same software running the device, but the device is faster (800Mhz PowerPC chip VS MIPS-BE at 680Mhz), has more memory (512Mb upgradable to 1.5Gb vs 32Mb) and more storage (think its 512Mb on board, plus 4Gb MicroSD card vs 32mb…). It also has more ports (13 GigE VS 5) and 2 Switch Groups, which i have no idea what they do just yet…

A couple months back, I got my hands on a Raspberry Pi, a tiny development board that can run a full copy of Linux, has a HDMI port, a couple USB ports, Ethernet and a few other little bits and pieces. The full specs, from the Wikipedia Article are as follows: Operating system: Linux (Debian GNU/Linux, Fedora, and Arch Linux ARM) Power: 2.5 W (model A), 3.5 W (model B) CPU: ARM1176JZF-S (armv6k) 700 MHz Storage capacity: SD card slot (SD or SDHC card) Memory: 256 MByte Graphics: Broadcom VideoCore IV There have been a few things i have wanted to play with it for, but have not implemented all them yet… still learning… but some interesting projects have come to my attention… here they are, in no particular order:
