mr mtwieg sorry if I was bothering you , but I found this circuit which steps up the voltage https://www.eleccircuit.com/dc-to-dc-step-up-voltage-regulator-by-lm2577/ but someone here has mentioned that using the lm317 with current regulating would disturb the circuit of the router and wont work...
ok this was helpful ! , that is what I was thinking of but couldn't get the name " boost circuit" , and for resources , most of them will be available , but I guess some would be not available of a company and it would be available by another one , I mean for example if an ic by National...
actully my battery is an NiMh , I didn't understand what do you mean , but actully today i have hooked the battery and it didnt work well, but it was giving only 6 volts , but now iam going to fully recharge it and try again , but shouldn't I make a circuit that would keep the voltage constant ...
ummm these r useful information , I should have known that , but what would be the difference if i dont use a lab power supply and I hook the battery directly ?
and u mean by that is that I am safe if I just hooked the V+ and the gnd of the battery to the router just like that without any...
you are totally right ,
how can I check if its needed ?
and if its like that , you mean that if i put this 8.5 battery with an lm317 and set the current to 1.5 A and plug it to the router it will be on and ok ?
thank u very much for the reply really

hello my name is Manar 4th year (stopped studying) computer engineering bachelor , and I live still in Syria.
As it can be called the silliest thing happening here , but it is annoying , that we don't get electricity most of the day .
I am...
Ok I see what you mean , but let me make a notice that as I said before I am not including any Micro controller to the circuit , the system is gonna be none secured , no password needed , I am planing to make the administrator turn on only one relay by pressing for example a tone , I haven't...
Oh my *** , you are just a helping man ! those info were almost perfect ! thanks a lot , I cracked up an old modem harvested the transformer and replaced the one on the circuit and there was so much different , the circuit works much better now , it recognizes all the Tones BUT , it didn't...
I am gonna try that , thank you Mr.Tpetar !
I hope that works , but I notice that this circuit is the same as the one I used but with a little more amendment .
if you may have the time to answer my following questions ...
are you responding to my post in respect to my problems ? or your giving...
