Yes they are.

You really don't need to quote when referring to the previous post.

Oh ok...

But what if someone sneaks a post in as I'm typing this?

Software of the forum will inform you when you're trying to send the message, if somebody was faster than you.

i wish i still had my 3 year old pics. Id take more (not) but its at work anyways.

Bare wires in fine as long as there are no shorts in your work and you keep all the spacings neat and straight. But once you are done prototyping you need to protect that. A huge blob of epoxy will provide the best structural support but its permanent. Hot glue is probably fine and at least semi-removable with a hair dryer or something.

What I used was thin (uhh... the red gauge from rat shack) 28ish gauge enameled wire. It is the same width as bare wire but it has a few microns of insulation painted on. It provides much better overall problem-proofing but you still wanna eventually encapsulate the wires so you dont rip them off one day. Do a pull test first, better to break off a few your wires now and do it again than to rip it apart when it dies randomly.

I used clear nail polish to "conformally coat" my work. We do the same thing to all the boards where I work but with a fancier product. Theres metal dust everywhere in the shop. It hard to trace; it can be nearly invisible. Anyways its pretty easy to remove nail polish as well.

So test it then put something on . Your job looks good. Take the 10min to carefully bend all the wires parallel , it makes look twice as badass for when you take larger pictures next time.

what software, and since when?

some forums do it I think. At least I think i've seen ones that tell you if you've been PMed since you started your reply. This one doesn't that I know of, and if it did I'd quote anyways.

yeah, i know some forums do, i just know this one doesn't. so i was hoping he'd inform me as to what the software for this forum is.

You gotta love those huge quote pyramids.

I got the expansion pak working after relocation, but the N64 crashes always after couple of minutes. Any idea, why this occurs? I have proper heat sinks on all four chips on the mother board and on the Expansion pak's chip. They don't get too hot to touch so I think that can't be the reason. Does the 3,3 voltages need to be exactly 3,3? My power supply's voltages changes from 3,2 to something like 3,45 volts. I haven't made the step down regulator yet.

[schmellyfart]

I think the 3.3v line is your problem. The n64 is pretty picky about the 3.3v line.

[Liuhuparta]

Sorry for lack of updates, but I hadn't had a chance to work on this one in couple of days.



Here's the spider-looking voltage regulator with reguired components. It heats up quite a lot, but it's normal, when reducing around 4 volts with 1,5 ampers. There's a lot of watts going for nothing sadly.

I'm still not quite sore, what causes the freezings and I hope it stops when I get the batteries. Then I'm going to make a led that indicates, if batteries are low.

[XCVG]

Does that regulator reduce TO 4 volts? If so, you've probably already fried your board.

[Liuhuparta]

It reduces around 4 volts away from the 7,4 line as I said. Of course I'm checking all the times, if it works.

[Liuhuparta]

Today I made a lot of progress, hurray!



Here's a mess where I tested SifuF's button combinations for screen's brightness and volume. It worked like a charm so I went and made a little circuit board for those chips (if somebody asks, two other resistors are on the back side).



I hadn't time for testing this thing, but I doublechecked everything so it should work. I'm still waiting for my batteries. After that I can measure everything and start to make the case mold!

never quite understood that...

great job, btw.

[Liuhuparta]

I'm just wondering if there's any way to get the voltage for 3,3 volt regulator from the PSOne screen? There's the 5 volt regulator, but I think it controls the brightness and I'm pretty sure it can't handle something like 1,6 ampers. It just feels stupid to waste some many for absolutely nothing, but I guess there's no other choice than using the 7,2 volts directly from the batteries. Atleast it keeps the console warm in winter.
