Mausberry Shutdown Circuit NES Build Help?
-
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.
-
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.
-
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!
-
hi qwaven can you tell me what tipe of usb adapter did you use and if you use any tipe of driver
-
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!
-
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
-
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!
-
@qwaven yes i have tried everithing, thank man
-
No problem, good luck!

Hello, first post and I'm getting ready to complete my nes pi. My question involves the maurberry circuit. Does it matter the order of the brown / red wire connection on the sw? Haza
-
@space-cadet I don't believe so. The switch is just detecting if the circuit is closed. Mausberry has a diagram on their website for NES power connections.

I'm about to start my own RetroPie/NES build. I've not quite bought everything I need yet, but I'm working on it. I'm in the process of working out all the details. I have a couple of questions:
-
Is the current model that is available on the Mausberry website different than what they have pictured? Looking at the pictures of their "Use your own switch" model, it looks different than that of the one you have. I'm just curious because if it's different, I'm not going to be able to use your guide, and will have to figure it out for myself (or ask officially in my own thread).
-
Are there any special scripts or programs or anything you need to do to make it all work? I mean, I see you have to connect the 2 wires to the GPIO. Does the Pi need a script or something to initiate the power down, or does it just know via the pins that a signal on them means to power off?
-
Are there any advantages to wiring up the reset button? I was thinking of maybe wiring mine to the "pair" button on a wireless dongle for an Xbox 360 controller. It might be more work than it's worth, so I'm looking for somebody to talk me out of trying it. :) Is it helpful having a reset button?
Who's Scruffy Looking?

-
Well to answer your questions.
-
The models look different but are fundamentally the same. I'ts pretty much a layout change and made them more compact. It also included a pad for a 3V LED. You can use the guide.
-
There is script to install but it's so easy to do. the instructions on how to install it are on the Mausberry site. It takes like 5 minutes and even someone like my self who is not very well versed in Linux based systems managed to do it.
-
I'm not sure how you would wire that the way want. But the reset button is pretty helpful especially in situation where the Pi has frozen for what ever reason and you can not use the interface to restart safely. Quite simply what you want to do sounds like more trouble than it's worth.
Hope this helps dude

Thanks for answering my questions. This is my first venture into all this, and I just signed up yesterday to post that question. And thanks for helping as far as what to use the reset switch for. I really was thinking it was good idea at first, but like you said it is probably more trouble than it's worth.
-
Since 1 and 2 have been addressed, if you don't want to hook up the Reset button to do a hard reset you could also connect it to GPIO and use it to control some function on the Pi. I'm not sure what that would be on a NES, but on my Super Famicom build I'm controlling what gets displayed on a secondary TFT. Just something to think about.
-
Sounds like everything was answered but to clarify the shutdown circuit I got is fairly recent so as far as I know the one you order should be the same as what you see installed on mine.
I'm not completely clear why you would want to switch the wires around but gather it should still work.
Follow this for the setup script.

@obsidianspider Yes, I was reading through your build progress. You have a lot more skill than I do. Even if you're just hacking it, I'm a total hack at hacking it. :) Your's looks awesome. As for the reset button, I'm just not sure what I want to do with it. Doing a hard reset sounds like defeating the purpose of having the mausberry at all. All you're basically doing is resetting it. If it's doing it "warmly", without doing a complete power off but just restarting the Pi, that might be something. I also like the idea you suggested in your thread of doing a reset button as a way to return to the RetroPie menus. Using an Xbox controller, I've got it automatically configured to use the "GUIDE" button to bring up RetroArch. I have to manually go in and close out of RetroArch using that. Surprisingly, once I set up the controller, the ability to use START+SELECT as a method of returning directly no longer works. Maybe it's because I configured RetroArch with the controller prior to actually launching a game through RetroPie? In any case, using the reset button on the NES to return to RetroArch sounds like a better possibility than using it for something else. Still tossing around ideas, haven't even received my console yet.
@qwaven Thanks for that link. I had seen that before, but just glanced at it and never read it. I saw that diagram of the GPIO pins on the right, and though maybe I clicked on the wrong thing. I actually read through it this time, and it seems simple enough to do. I just have to be in the console, run the download, run the setup, and reboot. Piece of cake. :)
