NesPi Case from Retroflag.com

I ordered mine here a couple days back - https://www.amazon.com/gp/product/B073ZC4TZY/ but they are all currently sold out.

@obsidianspider said in NesPi Case from Retroflag.com:

Sadly the same scalper mentality that ruined the NES Classic has taken hold here. :(

Well, they can either keep the price "normal" and at least sell the cases or they can raise the price to ridiculous levels and don't sell any or lot fewer.
Or maybe they can't keep up production with the requested amount so simply raise the price to reduce orders.

greekmanx

yes that is my video and I would love a script to make the power and reset more safe right now all it does it kill power temporarily for reset and until you hit power again for power button.

edmaul69

@nizz8 how much was it?

greekmanx

19.99 but no available at that price on amazon right now

NizZ8

@edmaul69 yep 19.99 like GreekManX stated.

HurricaneFan

Mine just came in the mail today. It looks pretty good and the working power and reset button is neat.

@hurricanefan i'm so jealous!! Looks good

@hurricanefan As i mentioned before i wonder if the shutdown button can be used with some modification with the mausberry shutdown script. Any insights into this @pjft , @cyperghost , @meleu ?

meleu

@rion yes I have: send one of this case for me and I'll give you a clean and efficient way to shutdown your system saving your metadata with no errors. :-)

Just kidding. We have no way to say how to shutdown cleanly with that button if we don't know how it works.

Did you buy it? Are there some specs on the web? When you get yours in hands we can hack it! ;-)

Cheers!

Rion

@meleu Sadly no. I was late to the party.

Maybe @greekmanx or @HurricaneFan can test them.

Hopefully there will be more of these available soon.

greekmanx

@rion what are we testing I am willing to try a script just don't know how to make one but would feel better if one existed the hard shutdown can scare some I am a little iffy on it

meleu

@greekmanx what do those buttons (power and reset) do? does it need any software installation?

HurricaneFan

@meleu The power button truly kills all power to the device when pressed. The reset button almost looks like you killed power for a second and it reboots the pi.

meleu

@hurricanefan wow! Quite rough, isn't it?

HurricaneFan

@meleu The power button reminds me of this power cord that I've used in a previous build.

Clicking the button kills all power to the device.

Rion

@hurricanefan Thats what I was afraid of. But we're not entirely sure that's the case just yet.

But if it is you should be able to modify it using a Mausberry shutdown circuit (use your own switch pcb). There's plenty of room inside the case to install it somewhere.

Hey guys, I posted a link to a tutorial I made for hacking this case's buttons to provide soft shutdown and reset if you're interested.

cyperghost

@rion There are three options now

Mausberry
Powerblock
Mosfet switch @Yahmez

I looked to his instructions and it should work... I saw several selfmade switches like that. You have one GPIO set to high, that delivers 3,3V ... as long as this GPIO is setted high the mosfat delivers power. When does the GPIO not deliver power? Right... if the Pie is shut off!
The cap will loose power and the mosfat output also closes.
--> POWER cutoff

As you press the power switch again
the Cap recovers power again = Switch acts as closed
Power to the Pi....

The solution is really good. And my explanation is just to simply to cover a detailed process description - sorry see it as shematic :D

Yahmez

@cyperghost
Yep, that's basically how it works. I meant to include a description of how the circuit operates but somehow forgot when writing it up.

Only thing I would add is that the power switch keeps the mosfet on as well, the pi's signal only really makes a difference after you switch off the power. The pi senses the power switch was turned off, and initiates a shutdown. Same goes for the reset button too.

Also, the mausberry and power block are both over $20 after shipping. The board I used was 7.50 after shipping and the other parts required are very cheap if you don't already have them in your parts drawer. So I'd say conservatively the mosfet method is at least half the price of the other options.
