ADVERTISE AT BOING BOING!
Sean Bonner shares word (and photos!) of initial prototypes for an iPhone-connected geiger counter, developed with folks in Japan in mind. (rdtn.org)
Wouldn’t a dosimeter be of more use to the folks in Japan?
Indeed this can be much smaller and it will. The iPhone allows for geotagging and logging, which are functions we’re working on right now. This is a concept to work out a new class of devices that can be mobile and easy for on the spot reporting. We’re also working on devices that are permanent monitoring stations. These will be much lower powered devices and could be run of solar or other sources of energy. Pieter (RDTN.org)
Doesn’t seem that large, get it into an electronics box set up a mount on it for the iphone to slide into and you’re set.
Solar Charging and piezoelectric charging would be cool, but I’m guessing this whole thing was put together in a piecemeal fashion with stuff laying around for the most part.
…and yay for the Sanyo Eneloop batteries. Those are some of the best rechargeable batteries I’ve ever used. I push everyone I know that asks about rechargeables toward the Eneloop line of rechargeable batteries by Sanyo. Mainly because once charged you can set them on the shelf for months and they still have plenty of charge when you finally need them.
Did people have the same fascination about measuring radiation when the US was doing all the nuclear bomb tests? That had to be of much greater concern.
If you read the site you’ll see this is only a smaller piece of a much larger effort. We didn’t actually do anything to an iPhone here, this is just a prototype of a very portable sensor that interfaces with an iPhone (or Android,or other mobile device) to transmit readings back to a central server while out taking readings.
Egh, I suppose it could be a lot smaller in the end, not set up on a breadboard. And transmitting data makes it make more sense than just being a stand alone device.
Did you follow the link? It *is* much smaller. The breadboard is just one of a series of photos showing how it was concepted and designed.
This is a cool hack but isn’t a few caps, a scale switch, and a analog meter more reasonable assuming a long term situation especially where much infrastructure is still washed away?
Solar cell charging or if possible piezoelectric charging a would be good to take the batteries completely out of the loop, the piezoelectric charge is used to power some cheap night vision device image converter tubes to lets say 30KV.
iPhone seems a bit unnecessary.
Right. It might as well have it’s own screen, there’s too many components and it’s too large, prototype or not.
It’s cool that they got an iphone to function with this, but it dosn’t seem practical.
except if you wand log it, for example with gps data included to map it etc etc.
Yes, the iPhone seems only necessary for rapid prototyping of the display. It really should have either its own display, or simply throw in some Bluetooth capability (or some other way) to interface with other phones. It’s a pity to handicap such a nice project with an iPhone. After all, not everyone has an iPhone and iPhones don’t run off of eneloops.
I thought The Power That Be (intentional singular) decried that “There Would Be No Geiger Counter App.”
What are the specs? What ranges of detectability? Can you get down to 20 keV? How can it be calibrated?
