100uF capacitor and 2k Ohm resistor
Moderator:Moderators
Hi!
I been searching but can't find what kind of 100uF capacitor I need for making a N64p(it exist more then one kind)
Do this one work: http://cgi.ebay.com/20-pcs-100uF-16V-El ... 0515730421
I will use a 7.4v li-po battery but don't know what kind of 100uF capacitor.
Will this work http://cgi.ebay.com/20-pcs-1W-1-2k-ohm- ... 0562545397 as 2k Ohm resistor?
Thanks

Sure will work but you could go with smaller resistors. Those ones are pretty big.

How many Ampere do the n64p's 3.3v line take? 3.3v/0.25w = 0.075A
Also I noticed that I choose 1.2k Ohm resistor

1/4 watts are fine

Re: 100uF capacitor and 2k Ohm resistor
the current does not go through that resistor, and its more than 1 amp IIRC

Re: 100uF capacitor and 2k Ohm resistor
Hey, a word of advice: Eurdrue and I have both had issues using 2k resistors. With our N64's, the boards couldn't handle the slight undervolt and would turn on, give interference with the AV signals, then turn off. I have mine hooked up with a 2k and am only getting 3.2v max, before switching to speaker wire I only got 3v. In our cases, I believe the board had less tolerance for the input voltage and simply just needed more power. I would recommend using a 1.8k resistor, which is supposed to give around 3.43 volts, plenty of power for the 3.3v line. I hope you don't have issues with your 2.2k resistor, the higher resistance the less voltage is outputted.

But if I use 1.8k Ohm resistor + 100 Ohm resistor then it would be better because I wont overvolt it and damage the motherboard?
Re: 100uF capacitor and 2k Ohm resistor
I dont think youll hurt it as long as its under about 3.7 volts, and if you put those resistors in series (connect them) then you will get 1.9k, which would probably work great. Test it with a multimeter first.
Re: 100uF capacitor and 2k Ohm resistor
^ - -^ results may vary; If (1.8K+100)Ω proves to be too much reistance, the 100Ω can always be removed/shorted out, or a 3.42KΩ can be put in parallel.
