Advanced Hardware-Hacking
Recently, I did a bit of »modding« to my homeserver (an old P30 laptop, you may know that if you're regularly reading this blog).I removed the case, which enabled me to remove some unneeded hardware to save energy. The touchpad, the internal modem and the front LEDs could easily be disconnected. The soundcard and the wireless card could also be removed, but they'll stay. The wlan will become a FreiFunk-node (stupid question: what's the english term for freifunk?). The soundcard makes it a perfect webradio player (and, for their mini-size, the quality of the speakers is quite acceptable).
Beside, the whole system now runs from a memory stick. A HD is still attached, but not used on normal operations. It tended to spin up without a reason, till I noticed that I still had smartd running. Now, the nice thing is, this device is now completely silent as long as I don't use the HD. Even if I run compile processes, the processor fan doesn't run. Seems that enough fresh air is sufficient to cool a Pentium M.
Another attractive feature is that I have three freely usable acpi-buttons, plus the three normal LEDs (caps, num, scroll). 3 LEDs, that makes 8 different LED-status combinations. My plan is now to use the three buttons, have 8 pre-programmed webradio channels and use one button for start/stop, one for switching channels. One is still left for creative purposes, volume control would be obvious, but that doesn't make much sense with one button. An idea would be to use the wlan-button and find a way to disable it's ability to switch the wlan-card on/off (at least a simple/hacky approach would be setting it back on as soon as it's switched off).
But that's not implemented yet, so don't ask for it. I'll publish it as soon as I've done that.
