The Aaron Swartz Day Solar Survival Team (led by Matteo Borri and Lisa Rein) has developed a “Vampire Charger” which enables a cell phone to be charged safely from whatever random batteries happen to be lying around after a disaster, while protecting the phone from blowing up.
After a disaster, this can be used with any kind of source of power that still has a battery in it. When you don’t know the voltage or current – and you don’t even know which is plus and which is minus or if it’s AC or DC – that’s the perfect time for the Vampire Charger!
Just connect the two input terminals to your “unknown,” and it gives you reasonably clean 5VDC to run your GPS or emergency radio with. Connect its two alligator clips to ANY two contacts of the part in question.
What a treat for us, to see this last weekend. We have been hanging out on the Hackaday website generally, since we submitted our Vampire Charger to it’s #PowerHarvesting Challenge. (Update July 25th: We made the Semi-finals!)
It’s always nice to see people finally getting to know the real Chelsea – and truly understand her ideas and techniques.
From the article:
I was lucky enough to get a seat very close to the stage in the main hall. The room was packed front to back. Even the standing room — mapped out on the carpet in tape and closely policed by conference “fire marshals” — was packed with people standing shoulder to shoulder. The audience was alive with energy, and I think everyone lucky enough to be here today shares my feeling that moments like these tie our community together and help us all focus on what is important in life, as individuals and as a society…
Hardware in hand, she started whittling away at the topics necessary to get back into the now. Among these, getting up to speed on virtual machine platforms, advances in network security, new warning systems, and the requisite mailing lists to stay on top of the latest research were on her short list. She mentioned that she thinks a lot of what once were tedious tasks have been tamped down through automation.
All of this, however, is the small part of her readjustment. When Chelsea entered prison she was only 22 years old. She had never lived by herself, and just learning how to find and rent an apartment was a big adjustment. Prison social dynamics do not jive with life on the outside and her discussion took the audience through what it has been like making the mental pivot to rejoin society.
