Mortal Kombat - 1up the 1up
« on: September 10, 2019, 05:47:36 pm »
It's been a while since I've made anything, so now that I'm living in a new city and got all my tools nicely organized... I figured it's about time to do something new.

I am not a big fan of the 1up Arcade cabinets, for many reasons I'm sure that many of you are not. The components are cheap, the build is cheap, they all look the same with different stickers slapped on them, no light behind the marquee, etc... But! When the Mortal Kombat cabinet came out and I got to play it, I was really wanting to buy one. That is when reality slapped me in the face and said, it's still a 1up cab. So, what I decided to do a couple weeks ago is beginning to design a cabinet in the size of the 1up cabs, but make it with the correct styling of the actual arcade cab that I'm trying to simulate.

My last cab I was going to make a 2nd "drop-in" control pane with Mortal Kombat control scheme, but I never got around to doing it. So I'm just going to build another cab. Right now, I'm waiting on the controls to all come in, along with a few other parts like the monitor and speakers. I figured I'd start sharing a little of what I'm doing with you all. I have lots of progress photos, but I'm going to hold off on posting those until closer to the end. For now, here is my 3D mockup. (I'm still working on the artwork, and I'm not sure if I will just go with the MK2 art, or something custom.


As you can see I also plan on making a custom riser for the cabinet. The difference in this build is that I'm going to be widening the control panel, ever so slightly, to accommodate easier access for two players. Also I will be running the emulation via RPi. I will end up putting a bunch of MK games on this thing.

List of Games:
Arcade - MK, MKII, MK3, UMK3, MK4 (if it can run on Pi)
SNES - MK, MKII, MK3, UMK3, (MK1 Blood Hack)
Genesis - MK, MKII, MK3, UMK3
32X - MKII
Sega CD - MK
Gameboy - MK, MKII (because why not)
Game Gear - MK, MKII (because why not)
PSX - MKT, MK4, Sub-Zero Mythologies
Additional Arcade games: Time Killers and Blood Storm

Cost of build (rounded to the nearest half dollar:

$98 - Wood
$0 - Tools, hardware, wires (already owned)
$44 - Joysticks, Buttons, wireharnass, USB encoder
$0 - Speaker Amp (already had laying around, I think it was $10 originally)
$16 - Speakers (not counting the $10 speakers that I threw away)
$0 - Monitor (found someone giving away old monitors on Facebook for free)
$0 - LED Strips for marquee (I got them a couple years ago for a different project, I can't recall the cost).

Optional costs:
$50 coin slot



[Update]

Well, I've been waiting for more of my parts to come in and ran into an issue. Bought some speakers on ebay and found out they were just grills, despite the auction saying that it comes with speakers. Anyway, I thought I'd post a few pictures while I continue to wait for my speakers to come in as the next thing I have to do involves installing the speakers. Since this thing is so small I have no choice but to wait. So anyway here is a bit of progress...

Wood waiting to be cut
 

Building the base
   

Measuring out the side and getting read to cut.
   

Starting assembly.


[Update 2]
Got my speakers in the mail today WOOOO! I soldered some speaker wire onto those 3" bad boys and hook them up to my amplifier and BOOM! At max volume, they are ultra-quiet, even though they were advertised as LOUD. Needless to say, I don't have much of an update. I've added some additional photos above that I took from before I ordered my speakers. Today I've ordered some new speakers and hope they don't take as long to get here and hope that they are much better. The reviews said they were "great" we shall see.  :banghead:
More to come later.

[Update 3 - 11-1-19]
I had a beautiful warm day today, so I took advantage and pulled my tools outside so I could get some more work done. Most of the big stuff is out of the way now. And as that speaker issue is now out of the way, I was able to get more work on the cab done. I've cut the speaker holes in the speaker panel and added the top and back of the cab. I have also added the back housing for my LED lights for my marquee.

[Speaker panel and top of the cab in place]


[cab back in place]
My next part to tackle will be the lock for the back of the cabinet as well as putting airflow out the back of the cab. Then on to the control panel, and then on to the monitor mount.

[Update 4 - 11-2-19]

Doing a test on the button spacing before sending my graphics to the printer. The joystick was just a rough cut, I plan on making a jig when I have the real thing cut.

[Update 5 - 11-3-19]

This is my first time using LED strips for lighting a marquee... I think I may have overdone it a bit. I'll have to go in and remove a couple strips as it's very bright. Either that or I will have to defuse the light a bit.

I like the idea, but why don't you just make it the correct size to begin with? Why make a riser?

To have an excuse to show up 1up, and then it's the proper size for my son.

[edit]
Or do you mean proper size as in Arcade size? If that's the case, I had to sell my Ms. Pac when I moved into this house because I don't have the room for it... I still don't honestly know where I'm going to put this one if my wife won't let me keep it in my sons room.

No I just wondered why it was necessary to build a riser instead of building a larger cab. Now I know. I look forward to your posts.

MK2 is still one of my all time favorite games.  Will be watching for sure.

Very cool! I'll echo Mikes statement and suggest you build the bottom to be the correct height from the get go. I have the Arcade 1up MKII without a riser in my girls game room, they are 7 and 9 and they can still stand up at it (but the 9 year old prefers a chair). They use stools for the full size machines and it doesn't seem to bother them one way or another, but they'll eventually need a riser.

Strongly suggest using something to create a CRT effect. if possible, make it a little deeper so you can use a 17" CRT. If you aren't going with full side art, that's a shame, but perhaps use black vinyl wrap to save some time. I've built some cabs with it and it's a real time saver.

Good luck! I think it's going to be great, but surprised all these 1up haters aren't telling you how terrible the size is going to be....

Look at lew trying to fish out some off-topic pollution to your build thread. Shame on you, Lew. Shame.

Hey, that's a quality 90% post I made. There is a small sharp edge to my post but it's 100% on topic.  >:D

:lol  well I'm not falling for that 10% bait.

I am with Lew on trying to fit a CRT in there, but I wouldn't adjust the depth to do so. I would look into a mirror set-up.  Have the CRT lay flat, facing upward inside the cabinet, then use a mirror to reflect the image to the front.   A lot of original cabinets did this BITD, and it helped with keeping the size manageable while supporting a CRT. 

You're probably not going to put a coin door in there, am I right?  Which gives you some real estate in the bottom of the cabinet to do a mirror set-up.

Mortal Kombat games are new enough that they look fine on an LCD. 
This forum needs more threads about Arcade 1Up cabinets.

It's actually way too late to make changes like that, I've already got much of the build finished. I'm just waiting for parts to come in so I can finish it. As soon as my speakers come in I can get the speaker panel and the top and back of the cabinet put together. Then when the joysticks and buttons come in I can work on some of that but will have to put it off a bit longer until I get my artwork ordered and in as well. I'm holding off on posting any progress because I want to post a lot at a time. It's been slow going as I've been working on this the past couple weeks because I have to do it little by little every time I get paid.

Added edit on the first post with an update.

Stupid eBay seller caused a delay, so I thought I'd toss a small update. I've got more completed than what the pictures show, but waiting to post some more. Unfortunately, my new speakers are not expected to come in until November. I hope that is a very liberal estimate on shipping time.

FINALLY! After 3 eBay auctions, I finally got not only what I asked for but something working and working well.
The first speaker order was to come with speaker and grills (they send just grill and claimed that the auction was not for speakers, I guess it was an issue of bad English).
The next order got speakers in horrid condition and was extremely quiet (even though they said they were "loud" speakers).
The Yellow speakers were the ones I got in the mail today and work very well.


I worked on the speaker panel today, but the weather is getting really cold now, so my time in the garage will be very limited. I still hope to finish this before winter is over.

Speakers are not inherently "quiet" they are designed to work as a load on your amp... That is to say a "Loud" speaker is most likely for a PA system and normally a 16ohm speaker, Why it is quiet is because your amp most likely is for 8 ok r 4ohm...Not enough to drive them Miss Daisy.

Funny, but I ran both sets of speakers from the same amp and they were worlds appart.

OMG thank you! as someone who has worked in the Audio/Electronics field professionally for years, I have heard the speakers blamed for volume so many times, I've gotten quite tired explaining that they are simply a vessel for the sound, the amplifier is what drives them. Excellent explanation here.

That is probably because the impedance (resistance) of the new speakers was probably lower, 8 ohm or 4 ohm are most common. The lower the impedance, the higher the output from the amp.

In most applications, you can get double the power output of the amp by cutting the impedance of the speakers in half. As long as the amp can handle the load. For example, an amp puts out 20w at 16 Ohms, 40w at 8 Ohms and  80w at 4 Ohms. *note- these numbers are arbitrary and only used for this example, I do not actually know the impedance of the speakers or power ratings of the amp*

I like this idea of the cab btw, and happy you're getting the sound you were after!

Well, thank you for trying to explain that to me. I knew the sound was dependant on the amp, I don't know how all the ins and out work with it... and still don't :lol. But, yes it was a 4ohms speaker set.

I have updated the first post with progress.

[edit]
hmmm... oddly enough they are both 4Ω speakers.

If your curious you could check those "bad" speakers with an ohm meter, My guess it is drawing more than the 4 ohm it is rated at...@ pjkjr : thanks, I get the frustration you know, And it is a deep ugly subject few people would have the patience to ever learn. Currently I am upgrading pin speakers, and the Flipper Fidelity set I chose say...run 2 8ohm speakers in series to be a 4 ohm load, *Jenn shakes her head* seems to me and the math that is wrong, but perhaps I am just overlooking the obvious.

If you run two 8 Ohm speakers in series then it would be 16 ohms, you would need them to be wired in parallel to get to 4. Judging by some of the posts I've seen from you on here, I feel like you know that lol. Sounds like who ever did the write up for flipper fidelity needs to brush up on either their math skills or their basic electrical theory.
