When all else fails, there’s radio. Hurricane Helene’s path of destruction through Appalachia stripped away every shred of modern infrastructure in some areas, leaving millions of residents with no ability to reach out to family members or call for assistance, and depriving them of any news from the outside world. But radio seems to be carrying the day, with amateur radio operators and commercial broadcasters alike stepping up to the challenge.
Those who haven’t experienced the destruction of a house fire should consider themselves lucky. The speed with which fire can erase a lifetime of work — or a life, for that matter — is stunning. And the disruption a fire causes for survivors, who often escape the blaze with only the clothes on their backs, is almost unfathomable. To face the task of rebuilding a life with just a few smoke-damaged and waterlogged possessions while wearing only pajamas and slippers is a devastating proposition.
As bad as a residential fire may be, though, its impact is mercifully limited to the occupants. Infrastructure fires are another thing entirely; the disruption they cause is often felt far beyond the building or facility involved. The film below documents a perfect example of this: the 1975 New York Telephone Exchange fire, which swept through the company’s central office facility at the corner of 2nd Avenue and 13th Street in Manhattan and cut off service to 300 blocks of the East Village and Lower East Side neighborhoods.

Members of Pixelbar woke up to shocking news on Wednesday morning this week as they learned that a fire had destroyed the building housing their Rotterdam hackerspace. Pictures of the fire are pretty dramatic and show the entire building ablaze. We’re not familiar with Pixelbar specifically, but most hackerspaces seem to share space with other businesses in repurposed warehouses and other industrial buildings, and it looks like that was the case here. Local coverage doesn’t indicate that a cause has been determined, but they do say that “large batches of wood” were stored in or near the structure, which likely contributed to the dramatic display. There don’t seem to be reports of injuries to civilians or first responders, so that’s a blessing, but Pixelbar seems to have been completely destroyed. If you’re in a position to help, check out their GoFundMe page. As our own Jenny List, who currently lives in The Netherlands, points out, spaces suitable for housing a hackerspace are hard to come by in a city like Rotterdam, which is the busiest port in Europe. That means Pixelbar members will be competing for space with businesses that have far deeper pockets, so anything you can donate will likely go a long way toward rebuilding.
Continuing the concept of saving planet Earth with gnarly, repeatable hacks, the fifth and final challenge of the 2022 Hackaday Prize is all about making the world better with smart and sustainable hardware. While the focus is still on saving the planet, this time, anything goes. Does your project not fit within the confines of a previous challenge? Here is your last chance to enter the 2022 Hackaday Prize: Start your entry today!
We’ve already run contest rounds that focused on green power generation, recycling, hacking tech out of the landfills, and just finished up making our world more climate-resistant and connected. How else do you want to use your hacking powers to make the world a better place? Well, that’s up to you. This is the wildcard round, after all. If your project helps to keep this planet running for future generations, you can enter it here.
The Save the World Wildcard challenge starts right now and runs until October 16th. As with previous rounds, we’ll award one of ten $500 prizes to each finalist, and the best projects will have a chance at the overall 2022 Hackaday Prize. So get hacking!
Following along with the 2022 Hackaday Prize theme on building a better world by doing what we all do best – hacking together solutions – the fourth round of the Prize focuses on making our local communities more resilient against and sensitive to severe weather and environmental disasters. Whether it’s an early warning system for wildfires or a distributed communication network that will keep working even when the cell phone service goes down, we’re challenging you to help make your world safer by reacting sooner and better. Get your project entered now!
We love systems that help us monitor our environments, and not just for idle curiosity or citizen science. Sometimes it’s critical. We’ve seen monitors aimed at giving you a personal particulate air quality indicator, especially helpful for people with respiratory problems when downstream of a forest fire.
But even better is networking these together to generate an air quality map, or to log long-run trends over time and space. CanAirIO, for instance, has both a fixed and mobile unit that can help map out CO2 and particulate matter quality. Or maybe it’s not wildfires that invade your airspace, but rather pollution from car use. We’ve seen projects like that before too, and anything along these lines would make a great entry into this challenge round. Could you predict local air quality?

Earthquakes are highly destructive when they strike, and unlike many other natural disasters, they often hit with minimal warning. Unlike hurricanes and floods, and even volcanoes to an extent, earthquakes can be very difficult to predict. However, in recent decades, warning networks have proliferated around the world, aiming to protect affected communities from the worst outcomes in the event of a large tremor.
ShakeAlert is the name of the earthquake monitoring project run by the United States Geological Survey, which has just announced that it now offers early warning services to the entire west coast of the United States. Let’s take a look at how earthquake monitoring works, how that feeds into early warnings, and how this can make a difference in the case of a major quake.

Last month, large parts of the southern United States experienced their coldest temperatures since the 1899 Blizzard. Some of us set new all-time lows, and I was right in the middle of the middle of it here in Southwestern Oklahoma. Since many houses in Texas and Oklahoma are heated with electricity, the power grids struggled to keep up with the demand. Cities in Oklahoma experienced some short-term rolling blackouts and large patches of the Texas grid were without power for several days. No juice, no heat.
In places where the power was out for an extended period of time, the water supply was potentially contaminated, and a boil order was in effect. Of course, this only works when the gas and power are on. In some places, the store shelves were empty, a result of panic buying combined with perishables spoiling without the power to keep them cold. For some, food and drinkable water was temporarily hard to come by.
There have been other problems, too. Houses in the south aren’t built for the extreme cold, and many have experienced frozen pipes, temporarily shutting off their water supply. In some cases, those frozen pipes break open, flooding the house once the water starts flowing again. For instance, here’s an eye-witness account of the carnage from The 8-bit Guy, who lives at ground zero in the DFW area.
