People have been converting their old Power Macs and Mac G5s into fish tanks for a few years now, but [Hayden’s] Internet-enabled tank is probably the most awesome ever crammed into an aquarium along with the water and the fish—and we’ve seen some fascinating builds this summer. After gutting the G5 and covering the basic acrylic work, [Hayden] started piling on the electronics: a webcam, timed LED lighting, an LCD for status readouts, filter and bubble control via a servo, an ultrasonic sensor to measure water levels, thermometer, scrolling matrix display, an automatic feeding mechanism, and more. He even snuck in the G5’s old mainboard solely for a cool backdrop.
The build uses both a Raspberry Pi and an Arduino Mega, which sit underneath the tank at the base. The Pi provides a web interface written in PHP and jQuery, which presents you with the tank’s status and allows changes to some settings. Nearly every component received some form of modification. [Hayden] stripped the webcam of its case and replaced the enclosure with a piece of acrylic and a mountain of silicone, making it both waterproof and slim enough to fit in the appropriate spot. Though he decided to stick with an Amazon-bought Eheim fish feeder, he disabled the unit’s autofeed timer and tapped in to the manual “feed” button to integrate it into his own system.
It’d take half of the front page to explain the rest of this thing. We’ve decided to let the aquarium tell you the rest of its features in the video below. Yeah…it can talk.

[Gigawatts] built a pair of USB ports into his mouse and there’s enough room to plug-in small USB drives and dongles. After seeing Thursday’s storage mouse hack he decided to tip us off about the post.
He started with a Logitech G5 gaming mouse. The wireless version of this mouse has a battery pack, but on the corded version this space is used for a weight cartridge. Since he didn’t really care about that feature he ditched the weights, added a USB hub inside, and positioned the dual ports as seen in the photo. The void is deep enough for the mouse to function normally while hosting medium to small-sized devices. This is a fantastic solution that’s at least as impressive as Apple adding USB ports to a keyboard. We’d love to see it as a factory option.
Update: Video after the break

Saying that [Ian] had some overheating issues with his iMac G5 would be an understatement. After losing three hard drives due to heat he decided to do something about it. The first step was replacing the thermal paste with Arctic Silver. The solution for the hard drive was a little more unorthodox.
[Ian] picked up a 320GB Western Digital Caviar Blue drive because of its very low noise rating. He used rubber grommets to mount it outside the case and ran SATA data and power extension cables through a quarter inch hole to the motherboard. He mentioned to us that the cutout seen above the drive is from a previous mod.
This certainly will fix an overheating problem but it doesn’t do much for the sexy style we’re accustomed to with Apple hardware.
