due to recent events and a natural mistrust when it comes to statements about security... i thought it might be useful to address radiation here.
after a quick search i found this neat thing. http://www.sparkfun.com/products/8875
from the datasheet:
Gas filling Ne +Halogen
Cathode material 446 Stainless Steel
Maximum length (inch/mm) 1.94/49.2
Effective length (inch/mm) 1.5/38.1
Maximum diameter (inch/mm) 0.59/15.1
Effective diameter (inch/mm) 0.36/9.1
Operating temperature range °C -40 to +75
it's not as small as i would wish it to be but still within reasonable limits. altho 500 volts are quite a bit, it is possible to deal with it.
power demand should be pretty low so a small li cell and inductive charging should keep it running for a day... or more. i am lacking precise numbers here but i don't see a major current demand other than the one needed to maintain the voltage.
anyone would be interested? ideas? thoughts?
btw..it really would be good if we can make a basic subdermal battery and charger solution since most projects need a power supply anyway.
Electroactive Polymers would also be good.
I posted it another thread and had mentioned some of the powering methods to you on irc. I don't know if any of them are feasible or not for this application.
I like this idea. Like the magnetic implant, this project could allow you to see into an otherwise invisible world.
EDIT: I just sent an e-mail to Amal Graafstra, asking if he would have any interest in reselling those implants through Dangerous Things. I think that would be an excellent way to make them more accessible to the community, but I don't know how feasible it is or if he'd even be interested.
EDIT: Yeah, no dice so far. Amal reported similar results the other day, so I'm going to go with vaporware on these guys unless we can get some solid evidence to the contrary.
Spoke to American medical implant designer David Prutchi, who writes The World of Implantable Devices blog. He says Sicel Technologies did reach the marketplace with its FDA-approved DVS implant. Unfortunately the company went bust three years ago.
