Re: Is this a sensible and cheap way to get 3.3v for the N64?
The 317 works a little differently from the 7805. The 317 has an input, a feedback and an output pin. To get the output regulated to the voltage you want, you need to have a feedback connection from the output. If you go to google and type LM317 you'll get a lot of sites to look at that will explain...

Re: Is this a sensible and cheap way to get 3.3v for the N64?
So are you seeing the 3.3v directly at the output (pin3) of the regulator? Or is the 3.3v in the middle of the resistor chain you have set up? From what I understood it seems like you're taking the voltage output from the middle of the resistors, which wouldn't work as a power supply. Once a load is...

Re: worklog: ZN-64!!!
Triple up on the wires! Just go for it! It's not going to hurt anything, it's fine. You can at least do that to test with while you try to get thicker wires.

Re: Four directional tact switch
In my experience the easiest way to make sure it's hooked up properly is to make connections to the pins on opposite corners from each other...diagonally across

Re: My N64p (56k warning)
Yah. I see the TI regulator in the middle of it. Is that all else it does? It also serves as a replacement for any mechanical switches you might use for turning the power on. It does automatic switching between batteries and a wall adapter, so all you need to do is plug in or unplug the wall adapte...

Re: My N64p (56k warning)
Thanks! Yeah, the time factor is going to be a challenge. The best way for me to overcome my earlier problem will require some more circuit design and a few more components, so it'll take a little time. I'm also trying to work on my thesis project at the same time and that kind of takes priority! Ma...

Re: My N64p (56k warning)
Yeah, it would be easy to wire up your own charging circuit. Just plug the wall-adapter line into the charger input. And since the batteries would be cut off you wouldn't have to worry about any sort of interaction between your charger and everything else.

Re: My N64p (56k warning)
Basically...the biggest feature of the power board would be that it completely replaces any power switches for your system. So you wouldn't need the bulky, high-current switch to turn on the power. The second part is that it isolates the batteries from the wall-power. It's designed so that if the ba...

Re: My N64p (56k warning)
With a good pair of small tweezers and a fine-tipped soldering iron...it's actually pretty easy. Well provided you have a steady hand as well. The parts would probably be about 4-5 millimeters apart. I'd try to keep them as close as possible to each other to minimize the overall size.

Re: My N64p (56k warning)
The board is designed around the PTH08080 regulator from TI. So the board is capable of taking any input that it can handle and outputting any voltage that it is capable of generating. So it should be fairly flexible for most of your needs. The parts should only cost about $10 (just as a rough estim...

Re: My N64p (56k warning)
The board would probably be about $20 each, with only a PIC populated. I would program the PIC with the generic program and would give the option of doing a little customization for a little extra. Whoever bought the board would be responsible for buying the rest of the components and soldering them...

Re: My N64p (56k warning)
I was thinking about designing another (better) board and selling it. Would anyone be interested? I don't want to put forth the effort if no one would even want it!

Re: My N64p (56k warning)
Thanks for all the comments! Having the Z button behind the L button is pretty comfortable. There are no games that use both the Z and L buttons, so you'll never have to awkwardly have a finger on each button somehow, so it work's out well. Or at least it has for me.

I used that PIC, which is designed for low power applications. I also set it to run at its lowest operating frequency and I put it to sleep when it's not being used.

Re: My N64p (56k warning)
Thanks everyone! Yeah, it is a bit thick that's for sure...but that's the price I paid for wanting everything enclosed, and I really liked the front design, so the only option was to go thicker. The case was custom built using a 3D printer, so that's where the lines come from. I got the work done fo...
