N64 Play and charge switch

[ToastBucket]

I found SS's to be a little difficult to understand. So I made my own.

That is a DPTT switch (pic is wrong. Soon to be fixed). When in the middle position the system is off. The middle position is the middle column of the diagram. Left is from wall power. Right is from battery and charger. Battery and charger leads are connected so it can be charged while running from battery power or while off.

That would bridge 7.4v from the battery and 3.3v. :\

Also, this still doesn't solve the issue of chargers lacking enough current for play and charge.

Also-why bring 3.3v into the mix at all?

This allows one switch to control the whole portable, although it is easier done with a switch before the 3.3v regulator, and this also saves power from the batteries. The way you have it set up the 3.3v regulator will always be receiving and regulating power and running down your batteries.

Take 3.3v out, have a separate power connector that outputs about the voltage of your batteries, done.

If you don't understand the simplicity of my flawless switch then I pity the fool.

That 3.3v line in the middle is labeled that way because from then on out it is the 3.3v line. It comes out of the switch as 7.4v, but then goes into the 3.3v regulator. I'm sorry if that was unclear.

Most chargers just simply do not provide enough current for the n64 and screen(plus the fan and everything else you might have) to be played while charging. This means you'll have to use a second adapter, yes, but this way works.

I'm going to do a full wire up of power here soon so people quit making mistakes.

New and improved. This is an actual DPTT switch and this is what I had in mind. If it's unclear tell me and I'll either explain it or make a better pic.

I'll draw it. Keep in touch.

 

[ToastBucket]

How is this wrong, SS?

 

[ShockSlayer]

When beta and I draw our amazing power wire up thing, you'll understand why this is overkill.

When that pcb beta linked gets in stock, things will be much, much easier and more convenient.

 

[ShockSlayer]

What PCB?

CMB. Charge Management Board - lets you use a normal wall wart to charge the batteries

 

[ShockSlayer]

Eh. If it were that important, I don't see why I wouldn't just uncase the charger and put it in the portable.

SS

Because most are huge and need wall power?

 

[ShockSlayer]

Misunderstood "wall wart."

Eh. Still seems pointless.

[ToastBucket]

SS, your diagram doesn't allow the batteries to be charged without the switch towards the wall power. Unless there are two leads from the + charger jack, one to switch, one directly to batteries. But meh, both of ours work.

By the way, my diagram is for use with the original wall adapter and the charger.

Probably not normal wallwart, more regulated wallwart.

I see nothing thats facepalmable.
