We announced the Hack a Day t-shirt design contest last week and entries have been rolling in. Check out the updated contest post for logo images and the font. Here are couple of the entries we've received:

The Polytechnic Institute of NYU is hosting an interesting embedded systems contest. They've constructed a solid state cryptographic device that uses a 128-bit private key. Contestants will be tasked with designing and implementing several trojans into the system that will undermine the security. The system is built on a Digilent BASYS Spartan-3 FPGA board. The trojans could do a wide variety of things: transmitting unencrypted, storing and transmitting previously entered plain text, or just shutting down the system entirely. The modified devices still need to pass the factory testing procedure though, which will measure power consumption, code size, and function. After a qualification round, participants will be given the necessary hardware to compete.

There's still time to enter io9's Build a Lifeform contest. Synthetic biologists, get cracking on the design of that synthetic lifeform or BioBricks lifeform! The rules are pretty straightforward; you need to propose a lifeform design that would be scientifically viable. The BioBricks lifeform part of the contest requires that your design needs to not only be scientifically viable, you have to explain how you would create it in a lab, and you get extra points if you already have an organism. The deadline is August 25, 2008. You could win the opportunity to attend an all-expenses-paid trip to the Synthetic Biology Conference in Hong Kong or $1000 and a chance to get your creature drawn by a cool comic book artist.

We need a new t-shirt. The current design, on the left, is entering its third year. Help us out by designing a new shirt to give away at conferences. Dash has donated a Dash Express for first prize.

Some ground rules:

• You must incorporate the skull and wrenches logo in your design. You'll find a larger version below.
• You can enter as many designs as you like to hackaday.shirt@gmail.com (JPG, GIF, or PNG mockups only please)
  
• The design can't violate any copyright laws or trademarks.
• The design should be one color and the shirt doesn't have to be black.
• By submitting your design you give us non-exclusive rights to use the image in the design of a Hack a Day t-shirt as well as for other Hack A Day promotional materials.
• We reserve the right to choose no design at all if we don't like any of the submissions.
• The contest ends September 15th.

The NYC Soldering Championships are happening tonight at Ignite in M1-5. It looks like there might still be some slots open if you want to compete. You can bring your own iron, it's all through-hole, but you can't use helping hands. Good luck, and we can't wait to see how this inaugural event turns out!

Last month we mentioned [bunnie]'s Name that Ware competition where participants try to guess the functionality of a random bit of hardware. We thought you might want to see another example; pictured above is the June 2008 ware provided by [xobs]. You can see a high res version here and an image of the daughter card as well. Be forewarned that someone has already posted the solution in the comments. At first glance there are quite a few interesting bits: board is copyright 1991, the 8-bit ISA connector doesn't have any data lines connected, just power, and it's got a lot of analog circuitry. Take a guess and then check out the comments on [bunnie]'s site to see the solution.

[Matt] let us know about the New York City Soldering Championships. They'll be happening during the Ignite talks on July 29th at 7pm. 25 people will race head to head to assemble a fully functional electronics kit. Participants have to register in advance and are encouraged to bring their own iron. The kit hasn't been chosen yet so people can't practice. We hope they at least consider using a few SMD parts just to keep things interesting. Shout out if you're planning to attend or compete!

Whether you consider yourself a bona fide mad scientist or you simply think your horrifying mutant creations are misunderstood, you'll want to enter io9's Build a Lifeform contest.

The contest doesn't require any actual primordial soup, just a concept of a synthetic lifeform you think would be useful or interesting. There are two categories with different prizes for each one. The first category asks contestants to use the BioBricks registry of standard biological parts to design a lifeform that could be created in a lab. Descriptions of how it would be made, what it would do, and potential hazards in creating it must all be included with the entry. The winner of this category will recieve an all-expenses-paid trip to the Synthetic Biology Conference in Hong Kong in October.

The second category is more focused on creativity, asking for the same descriptions as the first category without any BioBricks data. While this is the more speculative category, proposed lifeforms must still be plausible to create using current technology. The prize is $1000 and a signed drawing of your lifeform rendered by "a cool comic book artist."

Both categories offer pretty good loot for your concepts, just be sure they're more original than an esquilax if you intend to win.

For the background on BioBricks, check out [Drew Endy]'s Hacking DNA talk from last year. He's one of the judges for the contest.

[Joe Grand] is designing the Defcon badges for the third year in a row. Just like the previous years, they'll be hosting a badge hacking contest. This time around though, they're going to start leaking clues in advance. Earlier contests were often frustrating because of the specialized equipment needed to talk to the microcontroller. Hopefully this year it will be a lot more accesible. The specs for the badge have not been released yet, but after last year's 95 LED scrolling marque, we can't wait to see what this year will bring. [Joe] has posted info on the previous two badge designs and resulting contests.

Guessing games are fun, especially when unnamed hardware and prizes are involved. [bunnie] holds a Name that Ware contest on his blog once a month; he posts an image of hardware components like the PCB above (which is May's mystery ware) and asks visitors to try to guess the machine it came from or at least its function. Aside from the prizes he gives out, winners get the most coveted of all rewards: bragging rights. He's been running the monthly contest for quite some time and it's not always PCBs; past wares have included this micron thickness guage (internal) and an xray of a crystal oscillator.

Want to get your laptop custom etched... for free? During the next couple of months, I'll be giving away some free etching sessions. How do you get one? Just submit a fresh new hack via the tips line. If it makes the cut and gets published, you've got a chance to get your laptop or gadget etched in this 45 watt epilog laser cutter. Here are a few guidelines to help you win:

1. Make sure it's fresh. Use google for 10 seconds to make sure it hasn't been published on a major blog already.
   
2. Make sure it's got a picture - everybody likes a good visual aid.
3. You'll be more likely to win if you're submitting your own work.

Good luck!

I'm going to have a special guest in my workshop for a while: an Epilog Mini 24 45 watt laser cutter. This is entirely thanks to Epilog Laser down in Golden Colorado. Here's today's hackit: If you had access to your own 45 watt laser cutter - with a 12" x 24" work surface, what would you make with it?

Oh, and there's a prize on this one. Whoever comes up with the best idea will get a free laptop engraving session. (You can always just ship me the display cover.) You can have your own art put on, or we can always tattoo your machine with the Hack-A-Day logo.

(Pictured is Ladyada's laser cutter. Mine's coming tomorrow!)

This isn't quite a traditional Hackit, but I think you guys will dig it. Here's the challenge: Given a budget of $600, put together the best hacking workbench you can. Don't include computers or the actual bench in your budget. Oh, and you have to spend it all.

By the way, the best five submissions will get a chance to win a secret prize that I'll be announcing around the end of next month.

Last time, I challenged everyone to shout out with new ideas for those old TiVo boxes. The response was fantastic. I'm not feeling too exotic tonight, so I'll make it easy: The laptop. Years ago I found an article on using old laptop screens to make an electronically dimmed window. At tie time, LCD panels were $1000 items. Today, screens and old laptops can be picked up for a song.

Since 'Hackit' is a new idea, I'm still working out just how I'm going to handle it. Each week I'm going to bring up some hardware. You guys get to pick your brains and suggest new, interesting projects. Every so often, I'll tally up some of the best ideas and put up a bounty for pulling one of them off. Maybe it'll be cash, maybe some spiffy hardware - I'll let you know when we get to it.

So, got a better idea? Let's hear it.

(I'm in a robot mood this week, ok?) [Wyatt] sent in his posterbot. Lacking the gift of girly handwriting, he grafted an inkjet printer onto his Roomba to make posters for him. There have been other bots to do this, my favorite being the graffitiwriter. Of course, [Wyatt]'s bot is less likely to get you arrested.

Want a shirt?
By the way, I've got a spare Hack-A-Day shirt sitting here. Send in a link picture of your Hackspace to the tips line. The best/worst will get some attention and the best one gets an official Hack-A-Day shirt.
