Epilog Zing Personal Laser Etching

July 12, 2008 by 13 Comments

The new Epilog Zing is designed to bring laser engraving to the home for personal use. It’s got 25 watts of power, a small enough footprint to fit neatly on your desk, and the video above shows it has a pretty high resolution. But compared to the mini18, the Zing has less Z movement, a lower wattage, a smaller engraving area, and about half the speed. Also, with a price set around $8,000, we don’t think many people will be buying them for personal use just yet. However, if you have a small home business that requires these services, the Zing could be perfect. If you are looking for more information on laser engraving, see [ladyada’s] laser information page.

Touchkit – IR Multitouch Screen

July 8, 2008 by 11 Comments


If you’ve got an extra grand laying around, you can pre-order one of [nortd]’s touchkits. It features a unique custom made acrylic screen with a crap ton of IR LEDs embedded in it. An included IR camera provides the input and a projector (you get to supply your own) is used to light the surface. We mentioned this in our multitouch roundup and you can find a video of it embedded after the break.

GPS Logging Arduino Shield

June 28, 2008 by 6 Comments


ladyada continues to produce more and more interesting Arduino shields. This new GPS logger plugs into a standard Arduino board and has support for four different GPS receiver modules. On the backside of the board is an SD card slot where it stores the coordinates in a text file. The total runtime can vary from five hours to twenty depending on how you choose to power the device and how you use the device. How often you read the device and whether you maintain the GPS lock will affect the power consumption. Like all of ladyada’s projects, you’ll find a great construction guide and example code on her site.

RGB Etched Box

[Dine909] brings us this simple glowing box made out of five etched PCBs. The PCBs control RGB LEDs inside the box, which is also filled with clear glass beads. The four walls are connected to a base controller board that has a Cypress PSoC chip for color mixing. There’s no writeup, and even though it looks a lot like the Lament Configuration, it should be a lot easier to build; any transportation to other dimensions it provides will be strictly figurative.

Perceptual Chronograph

June 11, 2008 by 22 Comments


All praise to [Limor] for uncovering this incredibly odd project. [magician]’s perceptual chronograph is designed to test whether time “slows down” in stressful situations. The device flashes a random number on the display very quickly so that it is impossible to perceive what is actually being displayed. If you can read the number while under stress, it means that your ability perceive time has increased. It’s hard to believe, but check out the video embedded after the break that investigates the phenomenon. We can’t help, but wonder how [magician] personally plans on testing this.

Giant Fabric Keyboard

May 28, 2008 by 10 Comments


[ladyada] pointed us in the direction of this giant fabric keyboard built by [Maurin Donneaud]. The construction of it looks fairly simple, like the buttons used in [fbz]’s WiFi detecting backpack strap, but on a larger scale. We’ll take you through its construction, pictures and all, after the break.
