... rechargeable battery into the Pi. Now it's powered by 5v MicroUSB, I get that. So the question is, does anybody know of any compatable batteries that can either: be soldered/hooked up in some way to the RPi to supply power and can be recharged (preferably by USB without removing it, ...

<t>With regards the pipboy, flat batteries from phones would be the best bet. And i don"t mean discharged, but flat in profile. I have seen people making imitation pipboys with a lit screen and a transfer sheet to give the impression of a ...

... return of current you get from that type of energy is very small. They've started putting it into TV remote controls so that you no longer require batteries for them, however that only generates enough power to send a single button press at a time. Not the type of power to keep a device (R-Pi) ...

... or creating GUI's with ease (GUI toolkits include tkinter, which is built-in, wxPython, PyQt and PyGtk). It is also known as being "supplied with batteries", as there is a huge amount of functionality and modules that you can use from the off. It is supplied as default on Linux and Mac operating ...

... would that help? Size of the grid could be roughly the size of the rpi itself as I was planning to mount a teg under it and change a small bank of batteries when the device isn"t in use… I"ll be honest… Anyone for a actual working pipboy? they never see, to run outta power… And I had ...

... the whole time, how many Ah would you need to power it for say 24 hours? (worse case) If we could work that out then we could look for batteries that would suit. Then we could also work out what kind of wattage the solar panels would need to keep the battery afloat. Would ...

... I have got some very interesting Ideas if this turns out to be enough. If not, would the output of the TEG be enough to charge...say....4 AA batteries? Thanks, IMPhill</r>

... been posted. I assume that the solar angle on those chargers is a gimmick -- there is no way they can charge fast enough to make sense -- they are batteries that you usually charge from the mains, but can just about charge themselves in a few days of good sunlight.</r>

<t>Anyone know how to? Been looking on dealextreame and I realized I was basing my thought process on just going shoving a couple D cell batteries and going with that. Instead I could, I suppose, try wiring in a cellphone-like battery that would charge when plugged in. I want the raspi to ...

<t>Cheapest would be 4 NiMH AA batteries (nominal voltage 1.2, actual a bit higher), with a series diode (0.2 V drop). If batteries are good (low internal resistance) and fully charged this should give 4.6-4.8 volt. (USB spec ...
