A design of passive defense at the time was not convincing at all, because the noise of the bombs was that people would think that this would fall at any time. But this model of refuge, was more than a shelter: it was Catalan vault construction with exposed brick to withstand the force of bombs and entries ziga-defense to protect themselves from the blast of shrapnel. They were building bomb shelters a few meters underground to which could be accessed via the staircase of a block of flats or from the street. The solution Ramon Perera found most effective at the time, was under. The Generalitat de Catalunya, specifically from Passive Defence Board of the Government, commissioned Ramon Perera, an engineer of 31 years he was a member of the Board, to design a system that would allow people shelter from air attacks. Some historians say that these bombings were one workout prior to the Second World War by the Nazi armies, but what is certainly true is that civil society and the authorities of the time had to mobilize against a danger which threatened them day night.
Air raid monitor person code#
I hope it keeps people safe during these unthinkable times.”įind the code for the Air Raid Monitor on Dmytro's GitHub page.Barcelona was the first city bombed systematically against civilians in a war during the Spanish Civil War by the German and Italian air armies. “I have open-sourced the code and the instructions. Since posting about the monitor online, lots of other Ukrainians have also created their own version. “Last weekend, we were getting ready to go to the shop but, based on the data from the device, we postponed this and the air raid siren went off ten minutes later,” he says.
“It’s hard to get Raspberry Pi in Ukraine if you don’t already have one,” Dmytro reveals. The project has also led to the creation of a mobile-first online map at sirens.in.ua. I ended up putting the microSD card into a family member’s phone and using a text editor to configure the cmdline.txt and config.txt to SSH into Raspberry Pi Zero through the USB connection.” “The problem was that, even though I had a preconfigured microSD card installed in Raspberry Pi Zero, I needed to change the configuration in the ‘boot’ drive and a card reader wasn’t something I considered essential when packing my bag! “Not only does it show regions where the air raid sirens are active, it helps to predict a potential air raid by looking at the spread and progression of the attack – chances are that if multiple regions are hit, it will spread,” Dmytro says. The idea was to code a program that would monitor and parse messages in Telegram and create a visual snapshot of the current situation across Ukraine. When Dmytro began his project, the e-ink screen was already connected to Raspberry Pi Zero. Telegram became a way for officials to notify where air raid sirens start and stop.” Making predictions You subscribe to a channel you’re interested in and get messages with links, photos and videos from people who run it.
“One of these is ‘Channels’ – pretty much a one-to-many information distribution platform. “It has features resembling a social media platform,” Dmytro says. To do this, he turned to the popular instant messaging platform Telegram. I thought it would help to have a device that’s always on that could show this information about active air raid sirens across Ukraine.” “I noticed that my family would try and get additional information on the probability of air raids before going out by browsing through media and other channels. “When an air raid or shelling starts, we usually hear sirens going off, signalling that citizens should go to a bomb shelter or take cover,” he explains, of his motivation to create the device. “I know where all the load-bearing walls in my apartment are,” he laments, saying he now looks at old concepts in completely new ways. He says he never imagined that he would ever make such a device, but the war has shifted the paradigm of what is a must, a necessity, or useful. Getting air raid alertsīy using those two components, Dmytro has created an air raid siren monitor that shows which parts of the country are being shelled. Yet among the items he managed to grab before evacuating were a Raspberry Pi Zero computer and an e-ink screen – an odd decision, he admits, but one that has proven to be very useful. “I was in Kyiv when the first wave of explosions surged across Ukraine and we left the city with nothing but our backpacks,” he says. Dmytro is a Ukrainian from Kyiv, and he and his family are among millions of people displaced and suffering since Russia invaded their country.
