question about PTH08080

Hi,

I've seen the very nice skytronics diagram of how to wire this up & it is very helpfull, but does any one havea nice close up (or can they take) a picture of the actual item wired up?

I guess that part that is confusing me is where it shows the resistor connecting to the middle of the leg on the capacitor? I'm not to to sure how to do that. Thanks.

You can solder on the leg of the capacitor or on the board connector pin, whichever. Here is a pic of a previous one I connected; but found I couldn't use it on my current project as it was too thick (in fact, I actually had to snip down the connector pins!); so I used a different one. The capacitor is above the board and the resistor is over that, so they don't touch.

My camera doesn't have optical zoom, so this is the best I can get, sorry.

It is a bit messy, my solder vacuum broke a while back and I have now ordered a desoldering bulb! All works though, gives about 3.1v as I recall.

If you still need one, I can get one. Actually the pth08080 has a different diagram then the one that skyone(?) made, as it only has 3 pins and not four.

Yes, thank you bacteria for the photo.

SS, if you can take another picture that would also be appreciated. I'm trying to make sure I don't mess this up, so the more info the better. Thanks.

jeffslot - I can't take decent pics of small items, thought it better anyway to do an illustration for you.

Skyone's original diagram for the item you mention (credit to him):

Hope this helps - you can solder to the capacitor legs or the pin on the board, up to you. Red = input voltage (7.5v?) Pink = output voltage (about 3.2v or thereabouts). Black is negative for both input and output.

Thanks bacteria,

I'll give this a try & let you know how I make out.

Hi guys,

Well,

This is my 1st time attempting to solder something so small - it's a bit tougher than I though.

Well I'm not sure if you can tell anything from these photos, but here is what I've done so far:

I'm still not 100% sure where the negative from my unregulated power source goes. Well please let me know if you see any glaring issues. Thanks

Follow my diagram and you should be ok. Works for me. I have two negatives off the board, you only need one of course, I just do it to make it look complete.

Well,

I've finally got it wired up to a point where i was comforatble testing it. I'm only getting 3.12 v, though? Did I do something wrong? Will that be enough to power the 3.3 line? Thanks.

Yes, that's fine. Over 2.89v (as I recall) is absolutely fine.

You can get a different voltage reading if you want (you don't need to), by changing the resistor to 1k8 or 2k4 if you like; but stay as you are.

Sweet! that wasn't so hard. Thanks for all the help (now back to my secret project) Mwahahah -

For small soldering, a fine conical tip and 32ish gauge enameled wire is a must.

Hi,

I found this N64 Power Pinout that explained that

1 = Ground
2 = 3.3
3 = 3.3
4 = Ground
5 = Ground
6 = 12v

However I'm not sure according to the picture below how to tell where 1 or 3 is for that matter. Would it be similar to the way we read? Would it start in the top left corner? Help. Thanks.

This thread prompted me to finally getting around to ordering one of those free samples. Let's hope I'll be able to put it to good use

jeffslot, if you have a N64 wall power supply, you can look on the top of it - molded on the top near the plug is a diagram of the voltages.

If you look at the back of the N64 circuit board, you'll see several traces coming from the pins on the plug - those are also labeled if you follow them to the switch.
