Multi Function Device help needed, please! Answered
I've been toying with the idea of building a device incorporating several different devices, within one box - as small as can be practicably built.
Devices that I'm hoping to have installed are:-
(i) super bright led flashlight/torch
(ii) mono/stereo audio amp and speakers - 3.5mm input/output
(iii) built in re-chargeable battery (?V), with USB charge facility, wind-handle dynamo +(possible small solar cell?) - easy swapout to normal battery.
(iv) radio - FM/MW - anntena input needed
(v) emergency cell/mobile phone charger - USB to micro USB
(vi) internal USB type swappable memory, possibly with inbuilt MP3 support, linked to amp/speakers
(vii) clock/timer/temp guage
(viii) ANYthing else that can be built into a small unit!
has anyone else tried this kind of project? I have some (very rusty) electrical skills :) and would like to give this a try - but if anyone has done this kind of thing before, schematics and pics would be of great interest to me.
thanks in advance guys!
