Fresh hacks every day
Here’s a new take on the QR clock concept that uses an LCD display. The concept comes from the work [ch00f] put into his two versions of a QR clock (both of which used LED arrays). The time of day is encoded using the Quick Response Code standard. This version generates a new code each second which encapsulates date, … Read the rest
[Dearmash] put together this RGB LED display using triangles for each pixel. It’s an interesting deviation from the traditional grid layout. There are two video demos after the break. The first is a plasma-style pattern generated in Processing. The second is a spinning color wheel which would be perfect if synchronized with your Photoshop color spinner.
So the physical … Read the rest
At some point you’ve got to resign yourself to the fact that the TV you’ve been trying to resurrect is just not salvageable. But if you’re knowlegable about working safely with high voltage, you might get quite a show out of it yet. Here [Aussie50] finds beauty in destruction when he fries a large plasma panel from a broken HDTV.… Read the rest
3D display technology is fairly limited. Most 3D displays out there rely on either prisms refracting light from a normal flat-panel display, or shooting lasers into some sort of space-filling device. A few researchers in Japan went with a more unconventional method of making a 3D display that actually lives up to the promises of the displays seen in Star … Read the rest
The folks down at LVL1, the Louisville hackerspace, are throwing a Halloween party. To showcase his building skills, LVL1 member [JAC_101] put together a Halloween diorama featuring the inner workings of Doctor Frankenstein’s laboratory.
There’s a bunch of really neat pieces that make this build great. First up is the LVL1 plasma sign. This sign is four circuits pumping … Read the rest
Instructables user [Admiral Aaron Ravensdale] just finished a high voltage plasma bulb build that makes creative use of off-the-shelf parts. As a self-described steampunk, [Adm. Ravensdale] also earned some cred by included working gears in his build.
The heart of the build is a “flicker flame” candle light bulb. These light bulbs have two flame-shaped plates inside the bulb … Read the rest
Plasma speakers
Apparently if you run AC and DC currents through a welding torch flame you can use the resulting plasma as a loudspeaker. [Thanks Cody]
Power metering
The Google Power Meter API is no longer in development but that didn’t stop [Pyrofer] from finishing his metering hardware. It uses a reflectance sensor to read the meter instead … Read the rest
