NOAC wont start

Ok heres what I did so far.

I gutted the NOAC out from inside a SuperJoyIII (the kind that comes with pre-loaded games). I desoldered the remote the comes with it and also the 60 pin famicom connector. I was going to solder on my 72 pin connecter from my NES but after taking my NES apart and seeing how bulky the 72pin conncter inside was I thought I might be better of purchasing a Family Convertor and soldering that on. So I decided to test if the chip worked so far.

I desoldered the Audio and Video component plugs off the now dismatled SuperJoyIII controler ( the radio shack near me had none ). I soldered a wire from the second position of the NOAC to the Video plug and the third to the Audio plug ( using g-forces pinout ). I used the battery pack that came with the SuperJoyIII and connected ( soldered the wires to the NOAC and held with my fingers to the better pack ) the first position to the positive side and the fourth position to the negative side and plugged my TV in. Nothing.

Any idea's why? Should I solder the battery to the board? I was hoping not to do that since I'm just testing it, but if I need to I guess I can. Is it because I desoldered the 60 pin and didn't put anything in its place (the NOAC has pre-loaded games) ?If I haven't described it good enough I could take some pictures of it.

This might sound stupid, but did you make sure you soldered wires to the correct side? I connected wires to the wrong side before, but caught myself before connecting any power. I think its because you forget which side is which without the cartridge slot being on.
Just double-check, and make sure.
EDIT:

Do you have any grounds connected?

Again I didn't solder the Position 1 - 5v and Position 4 - ground to the battery I just held it to the Positive and Negative positions on the battery (respectivley).

I'm pretty sure its the right positions on the battery because I used the back of the SuperJoyIII controler as a guide.

Should I not ground my battery to the ground position on the SuperJoyIII? Or should I solder it to the battery (instead of just holding it there)?

I changed it a little but it still don't work.

I connected the Position 1 - 5v to the AC adapter port that came on the SuperJoyIII

I left Position 2 - Video connected to the Video component port that was on the SuperJoyIII

I connected Position 3 -Sound to the Audio pport that was on the SuperJoyIII

I connected Position 4 - Ground to the Audio port enclosure (I used that because on the pin of the Audio port where you connect the audio wire to it, there was some component [it was brown with a 104 on it] that had one side soldered to where the audio wire goes and the other soldered to the enclosure so I assume that was a ground for the audio??)

Heres some pictures,

Any idea's? I'm sure my lack of knowledge when it comes to electronics is probably what is killing me, now I wish I never dropped me Intro to Electronics class for the Cisco Certified Networking Academy class

i know that my noac has a regulator on the controller, you might want to check if yours does.

Ok here goes:

Make shure you have 5v going to the first pin, as you do. Then connect video to the center tap of a RCA plug, ground to the outside. Then connect the next pin to the audio (the same style as how you did video) Then the 4th pin is ground. connect the negative side of the battery here.

And that should work. I dont know if It works without the cart slot, but why not?

You don't have your video grounded.

Well thats pretty much how I have it except I'm using a 5v AC adapter now instead of the batter pack (as shown in my picture) and have the ground grounded to the Audio (no ground on the video).

Heres some new pics;

Better pic of everything soldered on

Pic of just the NOAC without the 60 pin (does it look like I could of fried the NOAC desoldering it, this was my first time desoldering anything)

Heres a pic of the solder point for the AC adapter

Heres a pic of the solder point for the Video port (no ground)

Heres a pic of the solder points for Audio port (grounded to the enclosure) what is the brown 104 component, and do I need it?

Anyone have any idea's on what I could be doing wrong? If I touch the Audio enclosure to the Video enclosure while the thing has power (theroretically grounding the video enclosure) and plugged into the TV, it shows some wierd things on the TV but nothing like what should be showing up.

edit//
I just noticed you said I HAD to have the Video grounded, i'm trying that right now.

You also need ground going to the power plug. Be sure you have the polarity correct.

I realized that was what I am doing wrong. So i'm desoldering all the stock wire from the SJIII and rewireing it. I'm pretty confident after I ground the AC Adapter all should be well.

dont just use the adapter unles it ouputs 5 volts

Indeed! If you are using the normal AC adapter it outputs something like 20 volts! It's instant death if you connect that.

Man i'm glad i read this i hooked it up wrong too

bioniclebert · Post by **bioniclebert** » Sun Oct 16, 2005 5:21 pm

and 5v DC not AC. Its better to go with batteries anyway, unless you plan to not make it portable

or you could make it like G-force's(?) genesis ondango (i probably butchered the name)
