This delightful marketing ploy requires the listener to fabricate their own record out of ice. The band Shout Out Louds wanted to make a splash with their newest single. So they figured out how to make a playable record out of ice. The main problem with this is the grooves start to degrade immediately when the ice begins to melt. So they shipped a mold of the record and a bottle of water to a select few listeners (just ten in all). Hear the result in the video after the break.
Now if you want to make something like this for yourself we can help you out just a bit. The mold is made of silicone and it wasn’t so long ago that we saw a guide for those new to mold making. The raw material isn’t that hard to find either. The project above tried several different approaches and found the best results can be attained with plain old distilled water. No, the one hard part is figuring out how to make your own master. If you’ve got a way of doing this in the home lab, please tells us about it!

Poor [Todd Harrison] spent all of Saturday and Sunday trying to make some ground-hugging fog for his Halloween decor. His fog machine hack turned out to be an utter failure. But he admits it and reports that he still had a lot of fun. Don’t feel bad [Todd], this happens to everyone from time to time. And anyone that has doubts about [Todd’s] skills need not look very far to find out that he does know what he’s doing.
The project started off with a theater-style fog machine. The problem is that this fills a room with a thin foggy-haze that doesn’t take shape outdoors. He wanted that ankle-deep graveyard effect and had seen several examples online that use a fog-machine with a bucked of dry ice. He though he’d just use his own bucket full of regular ice and salt water. Inside the bucket seen above there is a 15′ coil of copper tubing through which the fog machine’s output is passed. On the other side of the bucket there’s a plastic tube that goes to a sheet of plastic meant to distribute the cooled fog.
The problem here is that the fog machine puts out a hot mist. When it hits the ice bath the mist condenses into liquid form and that’s the end of the fog. As he attests in the video after the break, the dry-ice fog hack isn’t pumping out fog. It’s just using the heated steam to pump out carbon-dioxide vapor boiling off of the dry ice.

Want some fancy ice for your next cocktail party? You can try to find spherical ice-cube trays but you won’t get the kind of results seen here. It turns out the trick to this isn’t how you freeze the water, it’s how you melt the ice.
[Brendan O’Connor] started this project after seeing an ice mold that could make beautiful shapes rather than just cubes. But the price tag was $1400. If he could make his own at a hackerspace we’d bet that would pay his membership for an entire year!
The concept is pretty simple. The video after the break shows the mold he was trying to recreate. It’s two hunks of metal with a shape milled into them. The mold is pre-heated, then an oversized hunk of ice is placed between the blocks. The heat melts away the parts you don’t want, and leaves a perfectly shaped ice orb in between. Gravity is responsible for pulling the mold halves together as they slide along some machined rods.
With a big hunk of scrap aluminum he milled two halves of a sphere. They can be sufficiently heated if held under running water, and a some leftover printer rails keep the two parts aligned as the ice orb is formed. Now [Brendan] just needs to work on his method of creating a crystal-clear ice block as a starter and he’ll have achieved total win.

The Electronic Frontier Foundation, long-time defenders of the common man’s rights in the electronic realm, has published a guide to keeping your digital devices private when entering the United States. It seems the defenders of freedom and liberty (ICE, DHS, TSA, and CBP) are able to take a few freedoms with your liberty at a border crossing by seizing your devices and copies of the data they store for up to five days. This requires no suspicion of wrongdoing, and copies of this data may be shared with other agencies thereby negating the five day limit.
Do you have a reason to protect your digital property? This is discussed in the paper. It may be confidential information, by way of a business contract or professional relationship (Doctors, Lawyers, Journalists, etc.). Or you may just want to keep your privacy on principle. No matter what your stance, the EFF has covered all the bases in this intriguing read. We think the best advice they give is to make an encrypted backup of your data on the internet, blank your computer before the border crossing, and restore it when you get to your destination. If you don’t have the data with you, it can’t be compromised. It that’s not an option, they have plenty of guidelines on cryptographic techniques.

If you’re rebroadcasting copyrighted video streams how will the authorities ever track you down? Well it looks like you don’t even need to be the content originator, and they’ll track you down because you didn’t really cover your tracks in the first place. [Brian McCarthy] found this out the hard way when his domain name was seized by Immigrations and Customs Enforcement earlier this year.
So how did they find him? They started by getting the records from the domain name registrar. He had used an alias instead of his real name so the next step in the investigation was to get a name from Comcast to go with the IP which had logged into the name registrar’s interface. They matched the Comcast account holder’s home address with the one given during domain registration, then matched the Gmail account registration infor from the registrar to the same person. The final piece of the puzzle was to stake out his house (no kidding) to confirm that [Brian] lived at the address uncovered by investigators.
ICE really went the whole nine yards. Especially if consider that the website they seized provided links to copyrighted media but didn’t actually host any of it. Nonetheless, [Brian] could find himself spending five years in the clink… ouch.
[Rob] has made an astounding contribution in the effort to keep our libations chilled. Not content with merely refrigerating his cold ones, or even putting them in a cooler full of ice, he has built a beer caddy out of solid ice. Though it may look simple initially, you can see from his writeup that it actually took quite a few itterations to get it to freeze correctly, and then actually survive the process of removing the bottle placeholders. Ultimately, he found that glass bottles full of sand work best and you have to freeze the caddy in layers. Though he calls himself an impatient person, we’ve seen people who insisted on having their cold ones made frigid faster. You can see a video of the ice caddy after the break.

Moscow is in a bit of a hot spot right now, dealing with a heat wave and enormous wildfires. The combination of smoke, ash, and heat was driving Andrew up a wall so he built a contraption to provide some relief. It has two chambers, the bottom houses ice water, the top is an air baffle. A small DC fan pumps air into the upper chamber where it encounters the water being sprayed in from the lower reservoir. What results is a heat exchange similar to other diy AC setups we’ve seen. But Andrew also notes that after running the device for a while the smell of smoke and ash is gone. Can this setup be seen as an effective way to trap airborne smoke particles?
