Solid ice beer caddy

brrrrr

[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.

Hacked AC and ash filter

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?

Ice Tube Clock GPS

Our favorite Soviet-Era display that found its way into a present-day kit now displays time from orbiting satellites. A GPS module patched into an Ice Tube Clock with modified firmware will be able to provide a satellite-synced time. The firmware, modified by yours truly, parses the GPS module’s NMEA RMC sentences for the time and date information and then updates the clock’s time and date. Fun was had making sure the alarm went off at the correct times when the time was updated by the GPS. Overall, it was a fun project and we look forward to seeing additional Ice Tube Clock hacks.

Solar powered ice maker

solar powered ice maker
Producing ice without electricity just got a lot easier thanks to these engineering students from San Jose State University. Their system uses solar heat to facilitate evaporation of a coolant. When the sun goes down and the coolant turns back to liquid, its temperature drops drastically due to extreme pressure differences. The unit can produce 14 pounds of ice per day with zero carbon footprint. It has no moving parts and an entirely sealed system, this should mean that the only maintenance necessary would be keeping the unit clean.

Ice on Mars


It’s official: the Phoenix Lander has discovered ice on Mars. A few days ago, the lander exposed some bright white chunks of material while retrieving a soil sample. These spots have since disappeared over the following days, suggesting they’ve melted. An additional trench found a hard layer at the same depth as the original ice.

The spacecraft team has been dealing with some data storage issues as well and will be pushing a software patch soon.
