Fresh hacks every day
The concept behind this clock has been seen before, but [Dieter] tried to combine the best aspects of several projects into his HDD POV clock (translated). The basic principle of the design is to cut a slot into the top platter of the hard drive. This will let the light from some LEDs shine through. By carefully synchronizing … Read the rest
[IronJungle] had an old hard drive taking up space in his workshop, so he took it apart and wrote in to remind us how useful these old pieces of hardware can be. Aside from offering up incredibly strong magnets and donut-shaped mirrors, HDDs also come with a reliable stepper motor in tow.
He pulled theold drive apart, wiring up two … Read the rest
Hackaday reader [svofski] sent in a fantastic looking hard drive-based POV clock (Google Translation) created by a maker in the Sichuan province of China. The clock, like the one [svofski] built, relies on LEDs placed behind the spinning platter to create the POV effect.
Quite a few carefully placed cuts have been made to the platter, which … Read the rest
[Loreno Minati] built his own stir plate out of a hard drive enclosure. It’s the exact same hack as the one we saw a few weeks ago. A magnet was glued to the center of a computer fan, which causes the magnetic capsule inside the beaker to spin. This creates a vortex, evenly mixing the liquid.
Using a hard … Read the rest
[Marek Walther] uses a ThinkPad x41 tablet for business on a daily basis. Since he’s on the go with the device he figures that hardware failure is eventually going to strike and with that in mind he purchased a second unit – slightly broken – to fix as a backup. He had never been excited about the speed of the … Read the rest
Our friend [Sprite_TM] took a look at the security of a code-protected hard disk. The iStorage diskGenie is an encrypted USB hard drive that has a keypad for passcode entry. After cracking it open he found that the chip handling the keypad is a PIC 16F883 microcontroller. He poked and prodded at the internals and found some interesting stuff. … Read the rest
[Hubert] sent in his experiments using HDDs, CDROMs, speakers, and other components to make an XY laser plotter. Those carefully reading will note, its not all three to make one plotter, but rather three plotters each using a separate system. The setups have their advantages and disadvantages, and [Hubert] is sure to point them out; including circuit diagrams and pictures … Read the rest
