Hello & Good day to you all,
I'm making my own powercell for a miniature wireless CCTV camera (Link Below for specs)
http://www.bestofferbuy.com/wireless-pin…
After spending stupid money on sh*t 9 volt batteries (600mAh = £11 EACH) - ive had enough of the crap and absolutely absurdly LOW capacity 9 volt batteries out there (when TODAY's 'D' cell is capable of 11,000mAh !!!) and extremely high cost - i am making a battery-pack to power my receiver and another power-pack for the wireless camera using 8 x AA 3800mAh Ni-MH rechargeable batteries.
I should add that my existing 9-volt (2 new & 1 old) rechargeable batteries are a little-more-than USELESS (Rated @ 175mAh...{USELESS}) as the receiver drinks the power (juice, lol) at an extremely FAST-Rate... 15 minutes of use and its DEAD. 10 mins of use from the old 9 volt battery. And thats all from a 9 hour charge... How pitiful...Despicable, even...
Now i got the idea to use a semiconductor from an instructable to make a simple solder-fume-extractor... (Link Below!) and also i know that resistors can reduce the voltage and amperage output of a circuit..........
http://makeprojects.com/Project/Mini-Fum…
So my 8 x 3800mAh AA batteries = 9.6 Volts
But i need to add a semiconductor and a resistor to my battery-pack so that the output (in volts) is 8 volts MAX and output (in milliamps) is 200mA...
My question is which semiconductor and resistor ?????
I have calculated, researched, 'Googled', calculated again, more googled & now im going to give up and finally cry-out --- HELP !!!!!!!!!!!!!!
lol
Please please please can anyone help me find the components i need to make my very simple circuit for my battery pack !
I know that the use of a semiconductor (3 pin only) can let in a certain voltage and only output a specific voltage & amperage - i think i'll be needing a combination of a semiconductor and a resistor but i've searched continuous for 3 months now and am now irritated that i still haven't found what im looking for! ffs!
