First indieGogo funded unit went online

There are now three uRADMonitor units running in Poland. The last one went online this month, and even if it’s technically similar to the other two by being a model A unit, it is special because it’s the first indieGogo funded unit to go online, part of the first batch of perks delivered. Thanks to […]

Two hundred uRADMonitor units

Not long after the 2014 summary announced a first achievement of 100 units deployed globally, the network has already doubled its size, with a total of two hundred units installed or in transit to their new location. The new locations are many and it would be a rather complicated task to name them all in […]

Model A New firmware v111

With the uRADMonitor network covering more ground, constant effort is invested in making the project serve its purpose better. Code improvements come with extra features or better stability, and new firmware updates are released to anyone interested in upgrading their units. Firmware 111 is the latest code released for the uRADMonitor model A units. We […]

The Compensation Capacitor

Normally, the Geiger tube delivers a sharp short pulse, with an abrupt descending path, as the quenching gas very quickly neutralises the conductive ions, and so terminating the current flow. The uRADMonitor pulses appear with a slightly rounded tip because an extra capacitor is added in the circuit, named the “compensation capacitor”. All uRADMonitor model […]

Checking the Geiger tube

The Geiger tubes used in uRADMonitor model A units are mostly the SBM-20 or the SI-29BG, both of Russian provenience, manufactured at military grade specs. Therefore they were meant to resist fluctuations over a wide interval of temperature or pressure. If a tube failure is suspected for a particular uRADMonitor unit, for example when the […]

Model A firmware upgrade guide

As a project targeting global coverage, uRADMonitor was designed with all the important features right from the start: the units are plug and play, the network settings are automated via DHCP, the location is estimated automatically based on IP and so turning the unit on is enough to have a new node on the map, […]

A year to remember

2014’s last day is slowly passing by. For what uRADMonitor is concerned, the passing year was one to remember. It was 2014 where this entire project practically started: it moved from an idea to a prototype and then into production, for now to see it expand quickly all over the world. The solution is already […]

Hard to solder

​It’s been another day, full of…soldering. To cover the high demand, I’ve been hard at work producing more units for those interested in helping the network expand. Here’s more than 20 PCBs. Tubes will be added later, also the software, and the calibration tests. It’s a lot of work, but the neat results make it […]

Powering the uRADMonitor via PoE

When I received my URAD Monitor, I was trying to think of the best placement where it would satisfy the requirement to be outdoors but still remain close to a power source.  Having worked with PoE WiFi devices before, I contacted Radu to mention a PoE solution I was considering.  Since I was able to […]

Producing the uRADMonitor – New units available

In an effort of expanding the network even further, several new units have been prepared and are ready to ship. But, creating a device that will function perfectly in a distributed environment is not an easy task. Yet, from its relatively early start, uRADMonitor has already spread to all major continents and continues to grow. […]

Multiple new units joining the network

Some of you might have noticed the high number of units that recently appeared on the map around Timisoara. They are part of a new batch of units with some of them already in transit to locations all across the Globe. The units were tested and calibrated manually, to make sure they will function perfectly.

uRADMonitor Model A Video

With the approaching HackADay prize stage 3 competition, a new uRADMonitor Video has been added according to the competition’s rules. The uRADMonitor is a digital radiation dosimeter, enclosed in a rugged aluminium case. Designed to function as nodes, in a distributed network of radiation monitors,the uRADMonitor units are working together to achieve environmental radiation surveillance […]

Model A – Production Ready!

The uRADMonitor Project is a network of radiation detectors covering locations all over the Globe. The Model A is the first designed, it is an automated GM detector in a rugged aluminium housing which responds predominantly although not exclusively to gamma radiation. Count rate data is recorded and transmitted continuously via built in Ethernet adapter […]

Hackaday Prize 2014 Model A Video Presentation

To comply with the requirements of the HackAday.io “send me to space” Hackaday Prize 2014 competition, we’ve made a short video as an introduction to the uRADMonitor project. The video presents only a few succinct details, but for more information you can read the additional articles on the uRADMonitor blog. And don’t forget to vote […]

Producing the uRADMonitor – the circuit boards

The first uRADMonitor units were built by hand as prototypes, a time consuming task involving a lot of attention that often led to results of only satisfactory quality. Very frequently it was the PCBs that simply weren’t good enough when made by hand: defects were frequent and repairing them was nearly impossible. Luckily the usual […]

The Geiger Tubes

The Geiger tube is a gaseous ionization detector that uses the Townsend avalanche phenomenon to produce an easily detectable electronic pulse from as little as a single ionising event due to a radiation particle. It is used for the detection of gamma radiation, X-Rays, and alpha and beta particles. It can also be adapted to […]

Producing the uRADMonitor – the rubber gaskets

As the uRADMonitor Model A is intended as a environmental radiation surveillance tool, that should be run outdoors, we’ve designed a rubber gasket for the aluminium enclosures, to make sure rain will not get in to damage the components. Now finally we saw the first components getting out of their factories and wanted to share […]

Producing the uRADMonitor – the aluminium enclosure

Moving from manually built prototypes to an industrial production line, is a huge step especially for a project in an incipient phase, like uRADMonitor. Yet, with strong determination, obstacles melt away, opening the path for the first civilian environmental surveillance network, available to everyone, at anytime, to offer real time data on radiation level trends […]

Building the uRADMonitor

It’s been a long road getting here, a road paved with constant innovation. And it’s a longer road ahead. The first uRADMonitor was a crude prototype, with jumping wires on a test board, it got its own PCB soon. The following models were a new design, more compact using the smaller SBM-20 and SI-29BG tubes, […]

Unit in Odense, Denmark is back online

There is an uRADMonitor unit in Odense, Denmark that went silent for some time because of a failure in the high voltage internal inverter. This unit, part of an early set of first prototypes, was using a ferrite choke that eventually reached saturation with the increasing temperatures of the summer. As a result, the high […]
