I have a few excellent external batteries, the kind with USB female connectors used to charge phones. Now I needed a high voltage 12V battery, or more specifically something in the 6V-28V interval to power a uRADMonitor A3 unit. The form factor was important too, as I needed something more compact, a portable power supply with DC output. With a 3D Printer and a CNC Router at hand, a quasi-professional…
For a maker, there’s now no excuse in not using his/her creativity to the maximum extent. All the tools are readily available, you just need to think of what you want to do and shape that will into something real. Electronics industry now offers everything from advanced microcontrollers to low power radios, various sensors, displays, a multitude of module of all kinds and also pcb manufacturing. Take the latter as…
Some of the best moments are those when exciting technologies come together to create even greater products or results. This is such an example. Taking advantage of the latest IoT advancements, the LoRaWAN is a network protocol intended for wireless battery operated Things. Geographic areas ranging from the size of a city to the size of an entire country can be covered with just a few LoRa base stations, finally…
Introduction Environmental surveillance is a big thing. Important for our health, but also resource consuming when it comes to designing a system that works. I started with the first unit to monitor background radiation back in 2012, pushed that to global scale with the uRADMonitor project for most of 2014, then approached the air pollution problem with the uRADMonitor-D for half of 2015. And this is just the beginning. To…
This is an Open Source Digital Radiation Dosimeter, that can be used both as a portable detector, but also as a monitoring station to upload readings to the uRADMonitor network. This project is an update to the previous Geiger Counter Kit 1.0. When used as a portable detector, readings are displayed on the LCD. There is also a speaker that beeps on radiation events or is used to sound an…
There was a tough road to get the 3x Portable Environmental Monitor beta prototypes to the Hackaday Headquarters in time, but the effort was worth it! With today’s official announcement, the project has advanced to Finalist in the Best Product competition, and to Semifinalist in the Hackaday Prize 2015 competition. Last year it was a thrill as well, with the uRADMonitor-A advancing to Semifinals. With this previous project spread all…
The portable environmental monitor addresses pollution, the kind that we are unable to see but directly affects our health and causes life threatening diseases. Airborne toxic chemicals, radioactive dust and radioactive radon are correlated with cases of pulmonary cancer. Since our biological senses can do little to warn us of such possible dangers, the plan was to design the Portable environmental monitor as a first line detection and warning system….
I got a few esp8266 modules back in 2014, shortly after they’ve been announced on HackaDay. I didn’t have much time for them, being caught with other projects, up until recently when the portable environmental monitor project needed a versatile wireless communication mechanism, low powered and if possible at a decent price. The esp8266 seemed the best candidate, but like with everything in life where nothing comes free, getting it…
Note: there is a newer version of this project, KIT1.1, see it here If I was to give this project a version number, the closest match would be the uRADMonitor model B. Finally an open source compact radiation dosimeter, that has an LCD and thus allows mobile use, but also comes with an Ethernet adapter so it can do radiation monitoring (uRADMonitor compatible). Yet, this is not quite the uRADMonitor…
EDIT: there is a dedicated blog on this project, here. Make sure to follow it for latest news. A few days ago I announced my intention of creating my first crowd-funded project, but I didn’t tell you what was it about. Well, I’m planning quite a challenging project – to bring my uRADMonitor to a global scale, and create a network of distributed detectors, with data centralized on one server,…
Preparing for my first Kickstarter project . Let’s make it happen!
This page has been created to report unusual activity (radiation, temperature, humidity, luminosity, barometric pressure), as recorded by the uRADMonitor, including all the debug data to support the results. I cannot guarantee the measurement precision, I merely present the data recorded by the instruments.
