Mausberry Shutdown Circuit NES Build Help?

qwaven · 13 Sept 2016, 06:26

Hi all,

Wondering if anyone else has wired one of these shutdown circuits to their PI/NES?

If so perhaps you can help advise which wiring diagram I should be looking at...

I have one of these (direct plug micro usb one)
http://mausberry-circuits.myshopify.com/products/shutdown-circuit-use-your-own-switch

and I'm hoping to setup to work with my NES.

However I've seen this diagram on the manufactures site:

http://mausberrycircuits.com/pages/soldering-your-own-switch

However every project I've seen online for wiring a pi with a shutdown switch in a NES seems to follow this diagram:

The only difference being how the LED is wired from what I can tell. Sooo does anyone have any thoughts? It seems a lot easier to use the manufactures diagram but would like to get some confirmation before I actually do...

Cheers!

I'm not quite sure why you need to wire the 5V and Ground to the GPIO considering the Mausberry Circuit is what will supply the power and the ground for the power switches anyway. I've not wired up and NES switch to a Mausberry but I have got the same board you have, and I have used it to wire up a power and reset switch.

I'd go with the manufacturers in most cases especially when they know what people are using them for and took the time to work it out for you.

@qwaven I followed that diagram you've posted mate, but with hindsight you probably could use the connection from the mausberry instead.

That's also for an older version of the Mausberry board, one that didn't have The LED hole on the board. This is probably better to do it from the board as you don't need the resistor. You just wire the ground to RST-

You should always use a resistor when connecting a LED or you'll burn it out prematurely. That said, since the newer Mausberry LED circuit outputs 3.3V you would need to use a different resistor than if you were connecting the LED to 5V.

Hey all,

Thanks a lot for your input. My initial thought was to use the manufactures diagram. I think that seems like the best choice especially since the other diagram appears to be from an older revision?

If a different resistor is required would you happen to know what kind? There is no way this would have been already included on the board?

Cheers!

Here you go... From my NES conversion with the Mausberry controller... The only thing I had to do was to desolder the LED and reverse it's polarity (install it the other way)...

jsawhite · 14 Sept 2016, 02:06

oh, and pay no attention to the 2 brown wires attached to the bottom of the mauseberry. Those are used for ground connections for the NES controllers (connected to GPIO and using gamecon driver)

Hey Jsawhite thanks for the pics. I see a lot more wires in your PI. Are these all required for your switch setup?

My switch looks a lot different than yours so still kinda unsure. :)

I'm pretty sure I get where each wire goes from the NES buttons based on the manufacture diagram, however do I still require said resister, and if so which one? This is basically what I'm picturing...

Cheers!

Sorry, the extra wires going to the pi are for the NES controllers (I directly connected them to the GPIO). Yes, Mauseberry sells 3 or 4 different variants of the switch, so the boards have a bit different layout. Functions are still the same. No resistor is necessary for this setup. All you have to do is to reverse the polarity of the LED and you're done... :)

oh.... wait... you know what. I think I may have cut a trace on the board... let me pull it back apart this evening and I'll update... Hang tight.

jsawhite · 14 Sept 2016, 10:10

eh... had a few more minutes this morning, before work and pulled it apart again...

No traces cut on the button board! :) So easy connections (and a LED mod). The way you have the wires drawn should work fine.

Hey Jsawhite,

Thanks for your help.

So I've gone ahead and connected everything based on what I had drawn. Installed the correct GPIO mappings on the PI...etc.

The power switch (and restart) seem to be working great! However the LED does not appear to come on at all. Would you (or anyone) have any ideas? I'm hoping this is a user error and its not a faulty LED. :) I've attached some shots of what I've done below. They didn't all come out as clear as I had envisioned but I'm sure they will do.

Cheers!

did you take the led out and reverse it's polarity? You have to desolder the led, flip around 180 degrees and resolder it back in place. The current configuration has the positive lead shared with the reset switch. You need the negative. Just be careful you don't bend the leads too much as they can break off the led.

qwaven · 15 Sept 2016, 05:40

@jsawhite

Oops I forgot about doing that!! :)

Ok done desolder resolder and now it seems to be working wonderfully. Thanks a bunch!!

Now to wait for the rest of my parts and put it all back together. :)

Cheers!

Thanks again everyone for your help. In case anyone is interested this is what I've ended up with...

-Front "NES" ports are NES-USB adapters
-Cartridge bay has a USB hub
-LED, POWER and RESET buttons work
-HDMI and Power in the back
-Wii-U and bluetooth controller capable

Cheers!

elia27 · 17 Sept 2016, 15:08

hi qwaven can you tell me what tipe of usb adapter did you use and if you use any tipe of driver

qwaven · 19 Sept 2016, 12:55

@elia27

Hi Elia,

Do you mean for the USB hub? The hub is an Anker Ultra Slim 4-Port USB 3.0 Data Hub and no there are no drivers required.

Cheers!

elia27 · 19 Sept 2016, 13:11

hi, no i mean the nes usb adapter, because i bought this https://www.amazon.com/gp/product/B004L5KHKS/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

and did not work on retro pie

qwaven · 19 Sept 2016, 14:18

@elia27

Oh I used Basicest BAS1660 NES to PC USB Retro Converter Adapter for PC and MAC

https://www.amazon.com/Basicest-BAS1660-Retro-Converter-Adapter-Cable/dp/B014R069AI/

I believe there are drivers that came with it for PC...etc but I never installed for the PI. Are you using the latest Retropie/PI v3? If not you may want to try that first.

Cheers!

elia27 · 19 Sept 2016, 18:37

@qwaven yes i have tried everithing, thank man
