Preregistration for ToorCon San Diego ends today. The current price is $100 and it will be $140. This is the 10th year for the San Diego hacker convention which will happen September 26th – 28th. The schedule for ToorCon X has already been posted. We highly recommend this convention. We’ve attended the last four years and it’s always been a favorite.
Well, that was fun… no, not really, but we’re back from the dead like Steve Jobs. We’ve been getting DDoS’d since essentially the first day we originally came back. After killing a 1G connection, we decided to find a different solution. Since the world didn’t end this week, we brought the site back using WordPress.com as the new host. We now return to our regular blog shenanigans. Here’s to another four years of beta!
The last few days many people have been talking about the USC’s contour printer. It’s a device that prints concrete outlines with the hopes of eventually printing entire houses. Caterpillar has decided to back the initiative.
It reminded us of a project we came across at Maker Faire. [Leif Ames], [Matthew Bowman], [Marides Athanasiadis], and [Terrell Edwards] built a 3D Mineral Printer as their senior engineering design project at UC Santa Cruz. The printer works by first laying down a layer of dry concrete powder. It then selectively wets the powder where it wants a solid form. The reaction doesn’t require air to dry, so the next layer can be applied immediately. The printer only creates contours and the team imagines this being used to create temporary casting molds. The build envelop is nearly a cubic meter. When we talked to them, they were experimenting with many different types of material mixes. A video of the first test is after the break.

[conville] has been pushing standard HD44780 character displays to the limit. Embedded above is an example spectrum analyzer and text scrolling demo. Below you’ll find a scope demo. Both of these are created using a PIC 16F688 that dynamically rewrites a custom character set to create the animation. You can find the source code on mikrocontroller.net.

The Hack a Day Fail Whale Contest ends at midnight. It’s an easy way to win $100 in No Starch Press merch. Check out some of the entries in the Hack a Day Flickr pool. You can get logos and fonts from the Hack a Day t-shirt contest, which is also still running.

We’re back! There may be a bit of oddness for the next few days. Our Fail Whale contest is still running and we’ve received over 100 entries so far. Here’s how you can participate:
While we’re adding more hamsters to our server power plant we thought we’d hold a little art contest. Whenever Twitter goes down, they post the iconic Fail Whale. The Fail Whale has become so popular that it has spawned a dedicated blog and many many art projects: embroidery, tattoos, and laser cut models.
We want to see what you think Hack a Day failure looks like. Create an illustration, photo, sculpture, anything that you think embodies Hack a Day failing. Send your entries to hackaday.fail@gmail.com and add them to the Hack a Day photo pool. The prize is $100 for you to spend in the No Starch Press store. Entries are due 00:00PDT Saturday September 6th 2008.

The webcast for Google’s new Chrome browser starts at 11PDT. The browser is supposed to feature better memory management. Right now they’re opening with Led Zeppelin and Queen, so I guess it’s supposed to be rockin’ as well. Download it for Windows here. Chromium source available here.
