Good question, i dont know what signals would be affected.

[faint dune]

Posted this is taki's discord too. If you want to use Taki's case and the mt32-pi lite, here is a shim you can print to create enough space under the top piece so it fits.

[cinder crane]

ur a shim

[faint dune]

I'll make space for you anytime

[tardy hornet]

Nice thanks

[faint dune]

tested a couple sizes - 1.75mm was the sweet spot

although I wonder if just putting nuts in there would be better. the problem with the shim is that the top bows upward in the middle

[tardy hornet]

Weird I didn't get that...

I need to find someone who can print that shim for me at some point

[faint dune]

it's because the shim is thin enough that the screws can push it down at the corners and then the middle is higher than the 4 corners

[tardy hornet]

Ah

[faint imp]

Ironclad Lite: those two pogo pins were bent. Tried to unbend them and they just popped off from the PCB! Wondering what are those pogo pins for and if I should just throw this PCB away...

[shrewd dust]

How are you with soldering?

[faint imp]

Trace is too thin. It will be like someone with parkinson trying to do that

[shrewd dust]

Personally I think it looks salvageable, they're not that thin. Although I'm not talking about soldering the pogo pins to the traces, I'm pretty sure they're in that position for a reason.

If you can't do it then talk to the vendor

[faint imp]

That's impossible. Sending messages to @elfin pendant is the same as sending them to /dev/null 😒

[shrewd dust]

Sounds like you need to:

1. Figure out if the pogo pins are needed. Pretty sure they were mentioned in the What's Ken Making Video
2. If needed, either figure out a solution yourself or find someone who can
3. If neither of those work, throw it away, or sell it to someone who doesn't mind that its broken

[faint imp]

Mine is the old green pcb version with 3 pogos soldered so Ken’s video won’t help

I'm assuming those pogos being bent (and now broken) are the reason I don't get analog video/audio, so I will probably throw it away.

It looks like the broken pogos connect to ADC_IN0 and ADC_IN1

[faint dune]

is there really no way to reach @elfin pendant

[faint imp]

Maybe Twitter? But I'm not a Twitter user.

I offer 15 days “no question asked” returns, but if something is not working with your product, don’t panic, you are covered. You have a warranty of 1 year against factory defects, but even after that period I am offering free repairs/replacement for as long as I have the parts available to do it for that product, only shipping charges must be paid. Pleae, ask before sending the goods.

[faint imp]

If I'm reading this right, the broken pogos are for the ADC in:

Since I have no use case for those with the Ironclad Lite, there's hope

So the bent/broken pogos don't explain the lack of analog audio still

Just tested the MiSTer Pi with Taki's IO board and analog audio works just fine, so it's not an issue with the MiSTer Pi

Ok, so the old Ironclad Lite I have should be equivalent to the old MiSTer Analog IO Board v6.1. Do I have to set a jumper/switch on the MiSTerPi/DE-10 nano if I want to connect a non-9.2v IO board with the current framework?

I have two other Ironclad Lite setups with the DE10-Nano that don't need any jumper/switch toggle

@strong falcon do I have to toggle any switch on the MiSTer Pi if I want to use an old IO board v6.1 with it?

[faint dune]

It’s the same as on the de 10 nano

Or should be

[faint imp]

Ok, I will give this a try (after I figure which one is SW2)

[limber token]

I am bit confused now. I don’t know what is correct now. If I read here, there is no need to toggle any switches. The adc thing would not declare the missing functions. I think there is more not working.

https://mister-devel.github.io/MkDocs_MiSTer/basics/troubleshooting/

Where are you located ?@faint imp

[faint dune]

With the 9.2 board, you don’t have to toggle anything, the framework picks up if you have the analog daughter board or ram in that slot.

6.1 boards (which that ironclad lite is) still need a switch toggled.

[faint imp]

I have two other Ironclad Lite based setups using DE10-Nanos that everything works as intended without having to toggle any switches

[faint imp]

I will give this a try

Sent him an email

[limber token]

The trick for an quicker response could be to ask a question about a product you would like buying. I made the experiance, that he answered fast on such sales questions, but very slow to rma things (4-6 weeks)... Good luck

[faint imp]

Yeah, unfortunately their support is super slow to almost inexistent

[limber token]

That was one of the reasons why I have sold my ironclad.

[faint imp]

@safe marsh

[delicate hazel]

Someone in Taki's discord is having strange crashes with certain arcade cores. They are using a batch 2 pi.

The arcade games in question are:
(P.o.w, search and rescue, street smart)

And crazy climbers 2

They worked fine for me, no crashes or anything

[limber token]

There was a modified memtest, wich is able to test below 90 iirc. That was the time when the Mister pi first arrived.

Not sure if it was pinned here.

[delicate hazel]

Oooh

Seems like Jesus Fish might have found the issue. I don't think the display liked the Framerate.

[faint imp]

Jesus saves! 🙏

[sharp pulsar]

Not since the tariffs

[dense umbra]

My MiSTer Pi arrived the other and very pleased with it. Printed one of @gritty heralds cases for it. I also picked up a cheap USB C power switch from Amazon which works fine even with MT32-pi etc. No signs of voltage droop

[faint imp]

Do they use a different email for sales inquiries? I would like to try that because I simply got no answer about my RMA question 😒

[limber token]

Tried to dm you, but you have to accept the friend thing

[faint imp]

Ok, I feel stupid now! MiSTer Pi is working perfectly with the old Ironclad Lite

For some reason, @strong falcon sent me the MiSTer Pi with all of those in the UP position 😛

I should have checked that first thing but what a hell, it's working fine now!

[strong falcon]

Checking to see if you are paying attention

[severe stream]

Hahaha, but just to make sure (I’m new to this) in what position should the switches be on a stock MiSTER Pi? 😀

[faint imp]

https://misterfpga.co.uk/mister-de10-nano-switch-configuration/

Those 4 switches should be defaulted to the down position

[severe stream]

Perfect, thanks!

[winged summit]

In one of latest taki’s post about the Superstation he mentioned the dock have a “snac passthrough port”. Anyone have any info about that?

[shrewd dust]

Its been briefly mentioned over on his Discord at a similar level of detail. If you want to know more its probably worth popping over to this discord and asking him there

[wary turret]

There’s a Cheetos hopper to drop Cheetos into a tray when you pull a lever on the Superstation Flavoblast (tm) edition

[winged plinth]

Has anyone tried using mister pi as a development board for fpga? Not necessarily for mister stuff.

[dire merlin]

it is missing the usb blaster port, which is an issue if you want to use signaltap from quartus

[misty ether]

I had the same doubt actually, those external usb blasters don’t work to replace it?

[dire merlin]

maybe? I've never tried

[winged plinth]

maybe I'll try asking Taki

[sacred flint]

I think taki or one of his people has used an external one but check with him to be sure.

[sturdy orchid]

If it has jtag pins available it should still work with signal tap

[wanton trench]

This is Signal Tap

[cursive crypt]

Pins go to 11

[slim sundial]

https://tenor.com/view/spinal-tap-spinaltap-black-blacker-gif-3571403

why don't I get an image??? its all back?

[faint dune]

Working here

[severe stream]

Noctua fan + one more ram stick installed 😀

[gritty rivet]

I'm looking for an 3d STL of the MisterPi to use to design a case. Does anyone have one posted?

[faint dune]

I believe if you great @untold kayak ‘s step file from printables, there is a model of the stack in there

[untold kayak]

Yes it's close. If you load the case model you'll see some ports are slightly shifted to match reality of the Mister Pi units I received in batch 1 and 2

I originally modeled the stack based on availabile docs, but the units were out slightly here or there. I assume it's just production variance so design to account for that

I have the full Fusion files uploaded too

[crude kernel]

I thought that the mister pi couldn’t do 2 sticks of ram and the IO board?

Not that I’ve needed two but some say that it helps with SEGA, which has a great light gun selection

[sacred flint]

It should be able to.

Unless he didn't clone that side of the board exactly.

[winged summit]

what you can't do with 2 sticks of ram is the video analog output module of the IO

[shrewd dust]

It helps specifically with some games on the Saturn, but not the light gun games

[sacred flint]

The io 9.2 board has a removable mezzanine PCB that takes the place of the second sdram

[faint dune]

If you have a batch 3 mister pi, it may be the variant that doesn’t have one of the gpio headers because that ram is soldered into the board.

That variant still does dual ram, you just use the other header

(Removing the mezzanine as birdybro said)

[crude kernel]

Okay, mine were from the first batch, and I strictly use vga. I don’t believe I’ve even hooked it up to hdmi lol

[limber token]

One ram with analog io board or 2 ram with digital io board

[faint dune]

then you don't want to do dual ram unless you also buy an HDMI > VGA dac

[crude kernel]

Perfect, single ram it is! Thanks everybody for clarifying

[limber token]

90% of the mister stacks runs with one ram module.

[crude kernel]

Hopefully my composite adapter gets here this week. The seller on eBay was really helpful. I opened it up and it was a glittery usb cable and wall plug.
I sent him a picture and he noticed instantly that packing tape was used and he just used the printed label

I just am curious what the thief is going to do with a vga to composite adapter lol

[marble narwhal]

My MiSTer Pi just arrived. Third batch production run, it seems.

[cinder crane]

What do you call a Samurai Crow without a lord?

A Cronin

[marble narwhal]

I do have a lord though.

[cinder crane]

You do but a Cronin does not

GET IT

CROW + RONIN

[marble narwhal]

My Japanese is far from fluent.

[cinder crane]

So is my humor lol

[marble narwhal]

Oh ok.

[cinder crane]

Sorry, I was just making a bad joke. It’s a curse.

Welcome to the discord, really happy to have you. If you have any questions please ask away. We are very happy to help!

[marble narwhal]

Thanks!

[faint dune]

He is not kidding. He is happy to have you

[wanton trench]

So the sdram on the turbo pack is soldered to the board?

[faint dune]

yeah, on the new boards

[wanton trench]

So all the MiSTer Pi going forward?

[faint dune]

yeah I assume so

[wanton trench]

K thank you

[wanton trench]

@faint dune can another stick be added for dual

[faint dune]

yup. just pop off the mezzanine and put the 2nd stick in it’s place

[faint imp]

Why did he drop the Pis with onboard ram for this batch?

[sharp pulsar]

Not sure if I am parsing your question correctly but this batch does have BGA ram?

[tough whale]

yeah

[tough whale]

compatibility with handheld mods?

/customs

[faint imp]

It’s onboard BGA ram or a RAM stick with BGA modules? Advertising RAM module seems weird as it can lead to the reader to think they are external modules

@strong falcon pls clarify so we don’t have to consult the tweets

[strong falcon]

What's wrong?

[faint imp]

Are these v1.6 Pis with onboard SDRAM? I’m confused

[strong falcon]

Why confused

[faint imp]

Because you mention ram modules in there

[strong falcon]

The little IC modules

[faint imp]

Why are those compatible with other MiSTer boards?

[strong falcon]

That part is not supposed to be there....

[faint imp]

Agreed

Thanks for the clarification

[winged fable]

Be nice to poor ol taki..

[faint imp]

In Taki we trust! 🙏

And the page description is much better now, so the feedback was actually great!

Will skip this batch as I will be traveling by the time Taki will ship those. But I will for sure get the following one! 🙂

Gotta keep those MiSTer Pis coming!

[faint dune]

You are a stronger man than I

[gritty rivet]

does anyone know the part number of the tac switches that mister pi uses on the AV board?

[gritty rivet]

Small case design i'm working on for use without AV board or the USB hub.

[faint dune]

Oh niiiice

How do the buttons work tho

[high umbra]

Probably linked to pins 13, 15 and the other one

[gritty rivet]

I soldered in buttons, LEDs and the IO chip to the fan board. It is only is a few $ of parts. See https://www.reddit.com/r/MiSTerFPGA/comments/1fzl3w0/mister_pi_fan_io_board_is_an_unpopulated_digital/

[high umbra]

wait what I doing in here? oop

[limpid lodge]

You can even skip the IO chip if you only need LEDs and buttons, see my post halfway down on that thread

[final folio]

adapted a shell by Blazewind and Wizzo for the batch 3 NFC reader

[cinder crane]

Love the look!

[final folio]

It came out better than I hoped! It's thanks to the previous mentioned designs, baxysquares .svg logo and the nice marble filament

[faint dune]

nice to see a bunch of options for the mister pi NFC cards

someone did a nice PCE one too that I just caught a tweet for

[wanton trench]

I really like the look of it! I do have to ask- what's with the embossed SNES controller ports?

[dense umbra]

My 1.6 Pi board arrived yesterday, thought i would pick a spare up after selling my DE10 build recently

[sharp pulsar]

God bless the de10, I sold mine and got enough for it to buy a pi turbo kit

[high umbra]

How much are people paying for used de-10 nanos?

[cinder crane]

You mean a P.T.? Kojima never got one I heard.

[dense umbra]

I picked up my DE10 when they were cheap so only had £120 invested in it. I didn't lose very much

[gritty rivet]

trying to add some design cues to a console .. any other ideas?

[wanton trench]

Hmm not sure I'm trying to think of a console that's shaped like that 🤔

[jagged meteor]

New member here. I got a mister pi with usb hub today. I’m using an analogue IO board that I had as a spare. It was fully working from another build. I’m trying to use analogue audio and nothing is coming out. I have a 3.5 mm jack going to a mini amp which powers 2 speakers. In the ini. HDMI audio 96k is set to off. What the heck and I missing here? All my other builds work fine w an analogue audio?
