Naomi Projects - Update : PCB Holder

[Franco B]

Finally got back last night after two days of driving, dismantling, loading, driving, unloading and assembling. I did about 620 miles all in all but its all worth it now  



As you can see I picked up two Sega Naomi cabs.

The first one I picked up is a Net City with a Naomi 6 button CP with JLFs, 31Khz beautiful and clear 29" monitor, JVS wiring SF4 marquee and marquee holder and SF4 instruction cards. It also came with two 360 pad hacks installed, a 360 VGA cable installed and white stools.







The second one I picked up is a culmination of a few Naomis and the cab is absolutely mint. The previous owner repainted the whole thing, fitted new locks, bolts etc and it looks so fresh. The 31khz monitor has a little Initial D screen burn but its not too noticeable and the screen is crisp and bright. It has a Naomi 3 button CP with LS32's and also came with a dreamcast hacked pad. I also bought a Naomi cartridge board to complement the JVS wiring and I also bought a brand new marquee holder from him.







As you can see it does not have the leg covers on at present. The seller gave me two sets of full size leg covers, a used set of full size legs, a brand new set of full size legs, a spare monitor surround, bezel and light cover.



I need to cut the purple leg covers down and get them sprayed before fitting them.

As far as plans go for the cabs I'm pretty undecided right now. I think I may transfer the SF4 and 360 components over to the mint cab and then mame the other one.  I definitely need to hack another DC pad and dig out my VGA box for some DC schmup goodness

As far as maming goes I think I'm going to resray the cab to get it looking as minty as the other. Since I'm respraying it I may go for a different colour(s). I would love to use the Space Invaders artwork BASS! did for me so I may go down that route. I'm undecided on what lighting I'm going for as yet. I have enough spare LED Wiz's to go full RGB on all buttons, ball tops and RBG lit 8 way direction arrows around the joysticks. I'm not yet decided but I need to go fairly bling to showcase some of my current and upcoming components for my webstore once its up and running.

Anyway, I just thought some of you guys may like too see. There's plenty to think about but right now I'm off to play

[Ginsu Victim]

Nice find. Well worth the drive.

I hate you now, but that doesn't matter. Congrats! 

[HaRuMaN]

 

[Benevolance]

Wow. I am envious.

[King Nerd]

Beautiful cabs. I'm very jealous and envious.
I'd prefer a Vewlix, personally, but I would love any candycabs.
Good luck with whatever you do with them (especially if giving them to me is an option! )

[Gatsu]

oh I hate you so hard. 

those are just damn sexy...and look like they dont take up as much room as other candys....might have to get one of those instead of a egret or astro. though it does look easy enough to build. hmmmmmm   

[Franco B]

Cheers guys

I am soooo happy with them. This is actually the first time I have had ANY kind of setup in about four years. I haven't even had a mame setup in that time, I think the last time I had an install was about .103

I'm really looking forward to playing some propper games again and hopefully join in on the high score competitions you guys have. I'll lose miserably but it will be fun trying

Oh, I forgot to mention, I think I may get a multi-sync chassis for one of the tubes for some 15khz goodness.

King Nerd, I would love a Vewlix too. There were a couple for sale at the time when I was sorting these out but I was stretching myself as it was, let alone something four times the price

Gatsu buddy, there pretty mutch the same width as the Egret 2 and Astra City (infact the Naomi's look to be 10mm wider according to hard candy)

They do come apart very easily and can be compacted for transport. The lad who I bought the 2nd one of has transported one in his VW Golf before.

[Malenko]

$?

I broke my piggy bank getting a Namco Cyberlead for $550USD (with Naomi MOBO)

[Franco B]

Sounds like you got a good deal to me!


Ok here goes, (I really didnt want to add it all up )

SF4 Cab (everything included)- £550

Other Cab/Monitor on is own - £340
JVS/Naomi - £150
Brand new marquee holder - £80 (not cheap but these things aint!)

Total £1120

Looks like its super noodles for the rest of the month! 

[slapaham]

Congrats on the cabs Franco... haha, and you said I was extravagant with my cabinets!

V nice set up! Mame-ing one of these is extremely easy - I kept all the original wiring/mobo in mine as I love playing the originals (a bit of Virtua Tennis and Striker ) but as it's 31khz natively, you can just swap the VGA lead over when you want to play a bit of MAME/Naomi - so I quite often do! You just need a JVS-Pac - about £40 shipped from a nice chap in Norway and they work superbly!

I've managed to buggar my Naomi up somehow... nothing a bit of research (and probably cost ) won't sort out but it's frustrating as I'm not willing to play it until I fix it...

I'm sure you're going to have a lot of fun with these!

[Gatsu]

Looks like I'm gonna be scrounging up for a Astro once I get my vewlix finished.

[Minwah]

Nice!

[Franco B]

Cheers

Slapham bud, hehe I know I know, I couldnt help myself though

I'm building a new CP for the 2nd cab so I'm just going to put a IPAC in and then connect the PC straight to the monitors VGA port.

I saw your Naomi thread before I had picked mine up. I doubt I may be able to help but I'll go have another look at your thread now I have a rough idea of whats what.

Btw, if your ever over this way again feel free to come over for a game

I'm going to get this thread moved over to PA now. I've stripped the 3 button CP and I'm going to use it as a template to template route a new Acrylic CP tomorrow.

[crim6837]

Congrats to you!
That's a nice steal right there.
Where did you manage to find them?

[slapaham]

Yo Franco, just replied to your response to my thread - much appreciated on the offer! Just need to see whether it's my motherboard and if you could lend me one then I'd really appreciate it! Once I've concluded whether or not that's causing the problem then I can start to think of what needs doing!

All I can say is you're in trouble mate! It's like a tub of pringles, arcade collecting, once you pop you just can't stop! Before you know it, you'll be eyeing up even more cabs!

Yeah, if I'm ever in Lincs then I'll give you a bell, same goes for you in sunny Norfolk! Having said that I've just graduated and I'm thinking I may have a change of location relatively soon who knows where I'll be!

Got to say, I'm rather envious of those rather nice Marquees... daft thing is, they are worth a packet alone! You got some very nice cabs there, nice and clean!

Are you going to have some kind of system link-up set up? I played SF4 (arcade) over at Andy's (Segashed) when I collected my Naomi and while I didn't exactly play properly (I totally suck at SF4), the system link up was really nice on the 2 Net Cities he'd put them in! Doing a MAME system link would be very easy to achieve and would look good on your set-up!

[mlalena]

As you can see I picked up two Sega Naomi cabs.

And you put them in your bathroom. Seriously, that room looks to be about 6 feet wide.

[ddonaldson]

Ii desu ne?!

[Franco B]

@ slapaham: No worries dude, if you want to borrow the mobo just give me a shout. I know what you mean about the Pringles, I've picked up three cabs in as many weeks    Ooo, I hadn't thought about the link-up, that could be interesting!

  @ mlalena: It's actually our third 'bedroom'. We don't all have 1000sq/ft rooms over here in the UK We only been moved in about three months and it was just being used as storage. I much prefer it now!

@ ddnaldson: They sound great if that what you were asking

I've asked for this thread to be moved over to PA so I'll carry on with updates in this thread.

I've started work on the replacement CP for the cab on the left. I'm going to use 3mm acrylic but for a start I've been working on a CP template to use to route the acrylic.

I stripped the CP and traced the outline on some 12mm MDF:



I jigsawed the profile out leaving 3mm or so to clean up with the router. As the metal CP is so thin I used some washers to raise it slightly so it would run along the bearing and allow the cutters flutes to clear the top of the MDF so all of the material was removed:



Then it was just a case of trimming the excess on my router table:



I've not finished the router table as yet but you can see the top panel swings up to allow easy changing of cutters and adjusting the cutting height. I need to mount two lock arms I've made for it to keep the top panel elevated but a tool box works for now 



Pic of the template after cleaning it up a little:



Then just a test fit on the cab:



Not too shabby if I do say so myself

I need to get some black 3mm acrylic to continue with the CP now.

Whilst I was working I decided to change the washers for the JLFs on the SF4 themed cab as I don't really like the standard black textured ones.

These are the stock JLW washers, I'm sure you know what they look like:



I've made some acrylic replacements but I'm not sure which ones to go for. I made a gloss black washer, a gloss orange and a mirrored:







What do you think? I quite liking the mirrored at the moment.

[HaRuMaN]

Mirrored, def...   

[Ginsu Victim]

Mirrored is NIIIIIIIIIIIIIICE.

[Franco B]

Cheers

The other option is stainless grooved dustwashers and matching stainless 'Candy Cane™' JLF shafts.

[King Nerd]

Cheers

The other option is stainless grooved dustwashers and matching stainless 'Candy Cane™' JLF shafts.

I do like the stainless dustwasher, although I think I'd prefer a plain stainless shaft.

[Benevolance]

I'd vote for the stainless grooved washers. The mirrored looks really cool, but I'd be worried about keeping it all shiny and free of fingerprints. Unless I'm the only person in the world that rests his fingers on the base of the joystick between levels.

[Ummon]

Miles?

Um, shiny can be cool, but even with good stock it sometimes can seem plain. I also vote for the stainless.

Malenko, you may've broke your bank, but you got a ---smurfin--- smookin deal.

Gatsu: egret or astro city, all the way.

[evitagen]

So very nice.

The stainless washers look best to me.

Never having owned a candy before, I take it the CP isn't deep enough to hold a happs stick?  I've always wanted a candycab but I just can't get used to the japanese sticks at all.

Going to have to make my own, more than likely.

[Gatsu]

I think its deep enough for happ controls. I've seen a few happ modified candys around in other forums. Just don't see it a lot.

[Franco B]

Thanks for moving the thread Saint 

Yeah there is plenty of depth in the CP. I just had a quick measure and there is 8cm (3") at the narrowest part.

[Franco B]

Well I've ordered the acrylic for the CP and at the same time I ordered some 10mm black acrylic for some stools I'm making for the space invaders candy. I started work on these a while ago for my cocktail but I put them on the back burner as I didn't need them at the time.

I did have a CAD model of the stools but I can't find it after swapping PCs and HDDs around but here's a simple paint drawing:



The seats are each going to house a 10" blue lumin disc that mountain kindly shipped over to the UK for me. On top of the blue disc there will be a space invader cut of 10mm black acrylic. To make the space invaders I had some 8mm thick steel templates made:





I then used the templates and a 1/4" guided bit to cut out the space invaders. This is a picture of one of them laid on top of one of the lumin discs.



I decided to do a negative image of the space invaders as the lumin discs are white when they are not lit and so the space invaders show up as white. The lumin discs are light and touch sensitive. I did have some video of them in action but I cant find the mobile blog where I stored it but I have found this picture:



The discs and space invaders will be set inside the stools so there wont be the bleed around the edges that can be seen in that picture. There will be a 8mm piece of clear acrylic between the invaders and the disc to give some added depth and there will also be a 8mm clear piece on top which will be the part you actually sit on.

The top and very bottom piece of the stool will be made from 10mm black acrylic. I'm planning on using two rings of black/pinstripe chrome t-moulding and then either black leather or carbon fibre to cover the section in between the t-moulding.

As I need to cut lots of circles of various sizes I thought It was about time I built a propper circle jig. I've been following javeryh's excellent [Circle Jig Tutorial] and made the main body this morning. I hope to get it finished tomorrow.



The main shaft of the stool will be made from some 90mm stainless tube. I have the tube turned, it just needs polishing and cutting to length:



You can also see the lower coupling in that picture that will attach the 10mm black acrylic base to the shaft. There are tapped holes in the bottom to attach the coupling to base and then some grub screws will attach the coupling to the shaft.



I still need to make the upper couplings to attach the shaft to the main body of the stool.

[Gatsu]

will you be taking....custom orders for some stools? Because those are gonna be friggin sweet.

[javeryh]

Franco, you are totally crazy - I love it!   

I don't know how you convinced the better half to go for TWO candy cabs - that is the biggest trick of all  - nice work!

[Franco B]

will you be taking....custom orders for some stools? Because those are gonna be friggin sweet.

I would love to be able to make more but I'm afraid there going to be far too time consuming. I'm not looking forward to polishing all of the nook and crannys of the space invaders 

Franco, you are totally crazy - I love it!  

I don't know how you convinced the better half to go for TWO candy cabs - that is the biggest trick of all  - nice work!

Ha! Cheers bud.

She actually said to me the other night 'You know what, we need a pinball table now' then she followed that with 'Actually, what we really need is a big game room' 

She came up with the idea of builing one behind our my garage workshop. I told her that we need to buy the place first! (We're just renting at the moment but we want to buy it eventually). Still though, I'll hold her to that! 

[Gatsu]

thats cool. never hurts to ask though. hehe.

Getting the womans support is always good. My girlfriend doesn't know what to think about my arcade obsession. When I told her I was gonna build an arcade machine...at first she thought I was nuts. But after I showed her a few progress photos she thought it was a cool idea.

Now...when I told her I'd be buying another one....her first comment was "where are you gonna put it?" I just said I'd have to reorganize the game room. So shes fine with it as long as I'm the one doing the rearranging....not her. lol.

[evitagen]

Holy ---steaming pile of meadow muffin--- at those stools!

You are a god among machinists.

[Kaytrim]

Good to see you getting back to the projects Franco.  Let's see some more

Michael

[thatitalian]

You are a god... period

Small correction.

[Franco B]

Ha! I wouldn't go that far! 

Okies, plenty of pics ahoy!

I used the MDF template I made to route out a piece of black 3mm acrylic to make a new CP:



Although its a perfect fit it sits just slightly too high so I'm going to get a CP CNC milled from 2mm aluminium.



You can see the CP I am going to make here. I'm going to have RGB joysticks, RGB lit buttons and RGB lit arrows around each joystick. I seem to amassed eight LED Wiz's so I may as well put three to good use.

Pic of the modded RGB swivel JLF's I made:



You can also see the instruction panel above the CP. I'm going to use the SI graphics that BASS! kindly designed for me and I'm going to use the instruction space and the CP area for the graphics as the CP is fairly narrow and a lot of the graphics would be missed off.

Original graphics for reference:



BASS! is kindly tweaking the graphics for me to fit the new CP etc and is also designing a marquee and hopefully some art for the legs too

The two higher circles in the center will be player one and two start buttons and I'm thinking of installing the turbo twist spinner where the lower center circle is and using the SI spinner top I made:



Whilst I am getting the CP sorted I have been working on the stools some more. I made a template out of some scrap material I had at work to use as the template for the upper seat acrylic, lower seat acrylic and the base acrylic:



As you can see the spacies will fit inside nicely:



The black acrylic I ordered was six 300x300x10mm sheets. I needed to remove the excess material before template routing the rings. To do this I used the circle jig I made based of Javs design/how to.





Its basically the same as Javs, I just screwed it together instead of gluing it and made a knurled knob to fix the sliding block. I also added another t-nut with a long M6 bolt which acts as the pivot.

I marked the template out and drilled a 6mm center hole and countersunk holes in the corners to fix the material to my work bench.



In the end I attached the material to a scrap piece of MDF as the two surfaces of the work bench are not parallel and it was causing the acrylic to bend. It was then just a case of setting the cutting radii and cutting the rings out.



Just a safety reminder here, I had one of the bits break on me as I was routing. Always wear eye protection guys!



Pic of the routed out pieces:



Now I just need to attach the pieces to the template and route off the excess material. I have ordered some more flush trim bits which should be here tomorrow.

I have also had some luck on the monitor front. At the moment both candys have 31khz monitors. The one I am maming has some screen burn so I have been looking for a replacement. grantspain had some 29" (27" to you US guys) 15khz monitors shipped over from Spain and I bought two of them. This is one of them:



I have replaced the monitor in my Jamma woody with one of them and the picture on them is awesome! The monitor I had before had some serious colour issues which I couldn't fix so I replaced it with one of the 29"s and its loads better

This is the old monitor:



and this is the new one prior to decasing it and mounting it in the cab:



The best thing about them is they were only £50 each!

I plan to replace the burned 31khz monitor in the mame candidate with the other 29" 15hkz monitor. I just need to weigh up the best way to connect it to the PC. Either ArcadeVGA>JPAC or soft 15khz or JVS-PAC or whatever.

This means I should have mame running at 15khz and I should also be able to connect my Saturn. I will leave the 31khz in the other cab for Naomi carts, Xbox 360 and dreamcast which should leave most of the bases covered.

Whilst I'm on the subject of the other cab I have the DC and 360 hooked up to the monitor via a VGA switch:



The 360 has a VGA lead and the DC is connected though a VGA box. The DC looks awesome though VGA and me and the GF had a right 'blast' with some lightgun games last night. I played Confidential Mission for the first time and its great!



The candys also have some hooks on the back which are ideal to hang the DC guns as you can see in that pic.

Haruman is hacking me some DC pads and I'm going to add AMP connectors so the controls can be easily changed from Naomi>360>DC.

[javeryh]

Awesome looking!  I'd love to play some HotD2 with the wife but I don't have anything that can play it at the moment!  Those cabs look great!   

[Franco B]

Cheers bud. Yeah the 31khz cab is great for DC light gun games. It only hit me the other day that I would be able to play light gun games on it. I quickly grabbed the light guns out the attic and 'acquired' some gun games

Like you, I also don't have a full MAME cabinet in the house at the moment.  I've got 2 verticals and a now-gutted cocktail and an unfinished wood-grain upright but nothing complete that people can come over and play "anything" on.  I can get my fill of the classics for sure but I really wish I could play some gun, trackball and spinner games.  I promised myself I wouldn't be starting anything new until all current projects are at 100% so it is going to be a while...  I am drooling at that candy running HotD2... I almost want to go home and hook up the Dreamcast just to play it again...

[Franco B]

That's it bud, too much time making and not enough time playing! 

Did some more work on the stools today. I stuck the first ring to the template with double sided tape like normal but I was having problems getting the acrylic off afterwards. It can also remove the protective film from one side of the component and/or leaves a sticky residue which takes an age to get off. Seeing as the acrylic is 10mm thick I thought I would drill and tap the acrylic to hold it to the template.

I drilled thought the template and into the acrylic leaving about 3mm so as not to break through. I have found the best way to tap a hole when using a pillar bench drill (assuming you don't have a tapping box is to do the following:

Drill your tapping hole with the job securely clamped. Remove the drill and insert the tap into the chuck:



Bring the tap down to the hole and rotate the chuck by hand (make sure the power is off!) to start the first few threads.

Then just undo the chuck and raise the chuck/arbour with the tap still in the hole. You can then finish the tapping with a tap wrench:



This method ensures that the tap starts cutting in line with the hole and wont wander etc.

I used a 5mm drill as I was tapping M6x1 holes (you just subtract the pitch from the thread size to get the drill size on metric threads). I used a M6 spiral fluted machine tap and then ran a straight fluted M6 tap which I had ground the lead off to make sure that the threads went all the way to the bottom of the hole:



Then it was just a case of routing the excess off:



Here you can see one of the Spacies sat inside the top ring to give you a better idea of how the stools will look. The Spacie will sit 8mm inside the top ring and there will be a piece of 8mm clear acrylic on top of it to bring it flush with the top of the seat. There will also be a 8mm clear piece below the Spacie and on top of the lumin disc to give it a little depth and make the Spacie look like its floating a little:



Pic of all the pieces template routed and 6mm beveled:



To polish them I bolted the pieces back to the template and held it in a lathe. Its making them easier to polish but its still heavy going:
