The Invaders: 21 September - Some bad. But mostly good.
« on: June 08, 2017, 07:27:40 pm »
Hi all!

I've had this build on the back burner for about two years while i toyed with different ideas. For a long time it was going to be called ďZAP!Ē to go with Blip but i couldn't settle on artwork so decided to go back to basics and make it a homage to the granddaddy of vertical cabs:  Space Invaders.
 
It will be a single player vertical cabinet using a 21Ē b&o mx4000 for the main display and a 17Ē dell widescreen LCD for the dynamic marquee (because it's my thang!). As with my cube cabinet I'll be masking off half of the LCD to give me something marquee sized.
 
Before building the cabinet i wanted to make sure everything would work as i hoped it would. As Iíve just finished panelling a room, I had a load of offcuts and spare material I could throw together quite quickly. One brad nailer and 2 hours later and Iíve got this:
 





 
Yeah it's rough around the edges(!) but this was great for getting the height and angles of everything right before the main build. I tweaked quite a bit before i ended up with this and now I'm really happy with where everything is i can do the final tweaks to the 3D model and get ready to build the real one.
 
I've got a pretty good idea now what  i want the artwork to look like as it will be a mashup of space invaders art and the ĎThe invadersí tv show logo as i used to watch it with my folks when i was a kid and it really brings back happy memories.
 
I wonít be able to start on the build properly for a week or two as have to paint all that panelling but it gives me time to finalise the design a bit.

I should probably add that although the mockup only took 2 hours, i was working from an almost ready 3D model so it was literally a case of throwing wood together. The control panel is about the 5th version and i still ended up moving the joystick across 1.5cm so it didn't interfere with the spinner.

What i realised straight away was that i need to extend the front lip of the control panel an extra cm or 2 so that the edge doesn't dig into my palms when I'm playing centipede.

I'm debating whether i should show the final design now or let it come together in real time as i build it which could be more fun (and hide any mistakes i make on the way  ;D)

Thoughts?

following your progress.

How are you getting a marquee and screen out of one LCD?

His screen is a CRT tv. The LCD is the marquee.

The panel layout looks pretty good to me. Are there any vertical games that need three buttons?

Thanks - that's right I'm using 2 displays.

Gunsmoke was the main one but there may be others. I was this thinking 3 for modern shooters(?) but it's not something i know a lot about. If there isn't many that use 3 I'll certainly drop the extra button as ideally the panel will be as minimal as possible.

When you said vertical cab my brain instantly went to my cab. I have a vertical CRT cab, but I have a dedicated 4 way stick. That limits my game selection. I figured out that I only need 2 buttons.  ;)

Ah - I'll do some more research before i commit to 3 buttons then.

I'm using a servostik for this build so will dig some more

Tutankham is a vertical game which plays well with a 4-way joystick and 3 buttons for left, right, and smart bomb.  That's how it works on ArcadeSD, too.

Dinky - I like it! I say let the final design emerge - don't frontload it...

You going to sell that mock-up on Craig's List for $1,628?


As ever, following your build(s) with interest...

The mockup looks dinky but it's 180cm high by 54cm wide so not a lot shorter than the blip cabinet.

I'll keep the design to myself for the time being.

Artwork printing wise - who does laminated cpos in the U.K. now? I don't see it anymore on the pixart site.

I've been playing with the idea of using one of those B&O tv's in a cab but got a bit thrown off by the weird pcb system. Really curious how this ones will turn out.

I was looking over the frame again.  Man if it were just a bit deeper you could do a proper space invaders style of pointing the monitor to the back and using a sheet of glass to reflect it to the front.

I could definitely go deeper - the tv I'm using is REALLY shallow. I'll be decasing the tv this week so I'll do some more experimentation  ;)

Im in the same boat, mark. Pixart used to do textured vinyl, but now only seem to do floor vinyl. I sent them an email to see if they did the old stuff, but their reply was vague.
Im looking for some plain, black, textured and tough vinyl on a roll as im making modular cp units over time and thus need a stock. Let me know if you find anywhere!

If you're going to have a 4/8 way Servo stick on there, you might as well have the 3 button layout to support SHMUPS.  (ESP Ra.De comes to mind which has 3 buttons).

So I found some time to put the monitor mount together. Iíve done this a couple of times now so have a pretty good idea about how to do it, although I still exercise a fair amount of caution when I decase the TV.
 
Itís a Bang and Olufsen MX4000 which I chose because Iím a big fan of the picture quality, and they are ridiculously shallow. The downside (as mentioned above) is that the circuit boards are a bit scary when you first see them as there are about 6 of them all connected together via a plastic cage.
 
Luckily this turned out to be far simpler than I feared. The plastic cage keeps everything together really nicely and although I had to detach a couple of cables to get the thing apart it worked pretty well.
 
One great thing about the cage is that it comes on a sliding mount. I guess this was so it could be serviced easily but itís a great bonus as I reused the mounts to secure the circuit boards to my MDF frame.
 
I picked up some brackets for around £9 from Screwfix which were more than strong enough to hold the thing together so hereís where Iím at now.




 
Next job - the sides. I'm kinda excited to see how they are going to look...  ;D

OK... so this is piquing my interest in using a CRT on my next build... I'd imagine a B+O tube would be amazing quality butr wonder how  much you could pick these up for given B+O normally charge £9,452 for a remote control...

Suggestion:
I think a 30 degree angle on the marquee facing downward and a 30 degree toe kick would add a good amount of visual appeal from the front viewing angle and would give it more of a menacing stance to match the "invaders" name.

Overall, I like where this is going.  :)

The sidesÖ.
 
This part was a lot of fun (although lugging around 8x4 sheets of MDF in 30 degree heat takes some effort!)
 
I started by creating a template and tracing my side panel onto a piece of 9mm ply. This was purely so I could get the curves and angles correct without sanding for hours. The curve under the control panel was freehanded, but the top one was a bit trickier as I wanted it to be a certain shape. It took a couple of hours before I was fully happy but Iím pretty pleased with it.
 
Once cut I ran some black marker around the edge and took some photos fully side on. This was so when I create my sideart Iíll have the correct curve dimensions.
 
That done I flush cut the template onto 18mm MDF for the 2 sides.
 
The last time I attempted to do curves like this was on my Terminus cabinet back in 2009 so it was kinda fun to look through the old build pics of that to remind myself how it all went together!
 
So hereís the sides which should give you a much better idea of what the finished cabinet will look likeÖ (the one on the left is obviously the template!)
 


Next job will be to cut the base, top, back and furring strips...

Went through a lot of revisions before i settled on that one. Gonna have to some kerf cuts to get the front panel to follow the curve underneath the cp but I've enough wood to mess it up a few times!

Making the Base, Support strips and Dry build

Having to wait for some electrical bits and pieces for my panelled room so thought Iíd take a couple of days out and do some work on the cabinet.

I started by making the base - all fairly straightforward. I'm using cabinet wheels on the back and levellers at the front. Took a couple of hours to get everything right but here it is (not terribly exciting but progress!)



That done i moved onto the support strips. I've used a combination of pine (for the straight bits) and ply for the curvy parts. I used a thicker piece for the base support as that's where most of the weight will fall so makes sense to spread it as much as possible.

This bit took quite a while - mostly due to the curved parts which i made by tracing the side panels and offsetting them 20mm from the edge. For each support i made an exact copy for the other side which made doing the second side much quicker.



Nothing is glued at this point. The base is screwed with 40mm screws - the rest using brad nails. Once I'm happy with the dry build I'll take it apart and glue properly.

At this point i cut the top, monitor shelf, control panel and back panel so was able to put the parts together to make sure everything was square and in the right place.



And next to the original mockup :)



I havenít cut the front and top rear panel yet as I need to practice my kerfing first. Itís not a big rush through as I need to finish painting my panelling first (best to keep on the right side of the better half!)

In unrelated news my artwork is now 99% done so should be able to send that to the printers soon...

Loving yer work as ever, fella. Interested in your kerfing plans - how you approaching this? I once had to do that for skirting board (to accommodate my crap plastering..) and ended up making a jig for a tenon saw...

Left AND right. She knows where to kick too!

For the back curve I've just brought some 6mm bendy ply. I'll simply cut it to size and use the nail gun to hold it down.

The front is going to be a little more complicated so i need to put a bit of brain time into that one...

Mounting the displays

Hi all!

A fairly small update - I added the main CRT to the cabinet. I ended up setting it back a little further than Iíd originally planned because I thought it looked a better when standing in front of it.

I also mounted the LCD onto 12mm ply using the VESA mounts and secured them into the sides and flush against the top of the cabinet. This helps ensure itís straight and maximises the space available



I still have about a 1cm gap behind the TV which is close as I really want to get to the back panel. Hereís a shot from the top showing how shallow the screen is (and how tight it all is!)



...and finished by using some cardboard and leftover wood to get an idea for how much bezel space I need. For some reason I keep thinking of Robocop when I look at thisÖ I think because the marquee area looks like his visor.



Probably going to tackle the back panel next - and then the front panel and control panel which will mean the woodwork will be finished.  ;D

CRT for gameplay, LCD for a dynamic marquee?  I like where this is going (and I'm not even a fan of dynamic marquees!). I was just saying there has been a lot of uninspiring projects, but this is actually turning out better than I initially thought when I was just looking at the frame.  The design of the cabinet's shape is actually growing on me!

Yep - i had thought about using a 42 inch widescreen for the front to show bezels and marquees but it just felt wrong using an LCD for the main display when you can still get decent scart TVs in the U.K. 

The mockup was purely to test the ergonomics. I think the final design will make much more sense when the artwork is on as it should tie everything together.

Hopefully...  :)

Cutting the back panels

Or more specifically - the top panel as that's the interesting one.

I'd already glued the wood to support the curve so i picked up some 6mm bendy ply (correction: mdf) which i tacked and glued onto the supports. I had to use a few clamps to keep it tight against the top while the glue dried but it looks ok.





I'll have to use some wood filler to cover the nail holes and hide any discrepancies but overall it pretty much went as well as i hoped.

I even got to upcycle some of the mockup :)



Unlike the front panelÖ I had a couple of ideas on how to do this as it's basically curving wood in a couple of different places. I thought I'd try doing my own kerf cuts and while it partly worked it's nowhere near as clean as I'd like. I think i just put too much stress on the wood. I'll post tomorrow what i did for the sake of showing my mistakes but i do have another idea of how i can do it which i think will be more successful. Or maybe I'll need a plan CÖ!

Edited as used mdf and not ply.

Things donít always work out like youíd hopeÖ

So - in the interest of showing all - mistakes included I thought Iíd post my first attempt at the front panel. Even though it didnít workÖ

I started by cutting some 12mm MDF for the panel and marking out where the bends needed to be:



Then nailed a baseline in place and cut up a load of 9mm strips of MDF so I could use them to mark out the kerf lines



So far so good. Each strip of MDF marks out each line that Iím going to cut



Experimented with how deep I could go before the wood became unstable and settled on about 10mm with 2mm left for the front face



Cut some holes for the speakers and mini-marquee/admin panel and despite a few rough edges it was looking okÖ



Then. Disaster. The MDF totally split around the holes, as well as bevelling at the front.



Bah. Iíd say it was 3 hours down the drain but if anything itís reinforced my resolve to get it to work. Iíve just brought some flexible plywood that looks a lot more robust so Iíll attempt that at the weekend. If that doesnít work then itís back to the drawing board. What Iím trying to avoid is cutting the front panel out of 30~ strips of wood and gluing them together.

Iíll see how well the bendy ply works at the weekend...

Hard Cheese, Mark.. Mind you, he who dares wins..

Those lines are looking Kelly Brook, though...

Would imagine ply is gonna behave better.

Failing that, you could always steam jig it? Not MDF obviously, but some thin softwood?

That sounds like it might work - I'll try the ply and see how I get on first as I've already bought it. I've got enough for 2 attempts before I have to revert to plan C. :)

I dont know if you've sorted your artwork printing out yet(?), but I've been doing some research and will be going with Olly from ArcadeArtShop (https://www.arcadeartshop.com/). It's UK based. Price seems excellent for what you're getting and from what I've seen posted on Jamma+ the quality seems spot on.

HaRuMaN - I keep watching your avatar looking for the join and I can't find it...!

I'll look into that as well. I'm bloody minded when I want to get something to work and I know it should be possible. I don't know what it is but every build I do I make the front panel more complicated than everything else combined!

The problem I had - and I tried it a couple of times - wasn't the first curve, it was the second. Something about bending the wood one way and then the other just seemed to stress the wood/MDF too much. The flexi-ply that I've got seems much more forgiving so I'm feeling positive/optimistic/slightly drunk(!) that it can be done.

Cheers all  :cheers:

Please tell me you're going to do something unique with the artwork and not just photochop up the original Space Invaders art?

It's been a whileÖ

But stuff has been happening. I blame school summer holidays and looking after a very hyperactive five year old for a lack of posting. I also got made redundant which put a dent in my computer time but hey ho - on we go :)

The last installment had me failing at kerfing wood. I tried a couple of things since then using *really* thin MDF and even laminate but it all looked like crap so I sucked in and spanked out £30 on some bendy ply. Which worked!

I had to change my front panel a little because originally I was cutting too much out which was affecting the strength of the wood but Iím happier with how it looks now.

AnywayÖ pics





That was a major relief and probably the hardest part of the build so far.

That done, I sanded and filled, sanded and filledÖ





And primed



And installed the power inlet (no pictures).

You can see the control panel in the final pic as I've been doing some work on that too. I'll post a proper update when I've got some decent pics.

Iím now in the process of painting which I hope will be finished by tomorrow. Iím going for a light grey shade as the artwork will be quite bright. Speaking of artwork Iíve been getting some advice from a very kindly member here so Iím hoping that should be finished soon and then I can send it to the printers.

Woodwork finished so no more dust! Yay!

Thanks guys.  :cheers:

Painting is almost done. Outside is finished but for some daft reason i picked up an oil based black paint for the bit around the monitor so it's going to take longer to dry. I'll put a second coat on tomorrow and then that should be all the painting done bar touch ups.

The inside has been painted white just to keep it tidy.

Artwork is presently on hold because my new laptop has gone kaput. Bloody windows 10 and the start bar has stopped working. I managed to get around it for a while but now explorer won't run either. Looks like a full reinstalll is on the cards once I've managed to copy my files over. Grrr.  :banghead:

Painting finishedÖ

The last few days have been spent painting the inside and outside of the cabinet. The inside is white satin, with a black background where the monitor goes so that it will appear to float inside. The outside is a grey satin. It's nowhere near the flawless finish that some of you guys get on your cabs but I'm pretty happy with it.

Had some white t-molding left over from Blip so I've used that for the time being. Once the artwork is on i may order some orange but I'll wait and see how it all ties together.





I was also curious on how the actual bending wood was installed.

I used 5mm bendy ply which I manually bent around 3 9mm pieces of MDF for support. Here's a pic from inside of the cabinet so you can hopefully see what I mean.  I ended up doing this whilst the cabinet was on it's back and used a combination of clamps and very heavy weights to keep things together while the wood glue set.  It's pretty solid now.



Going to have a break from building for a couple of days while the paint cures a bit. Then I'll start mounting the displays, mounting the PC and sorting out the other 101 things that I always forget about when I'm building these things  ;D

Looks good!  One question though, why the T-molding across the bottom of the cabinet?  That just looks... odd.

Thanks! It's not t-molding- it's L shaped plastic edging. I'll be using it at the top to hold the bezel in too.

Also it covers my slightly shonky plywood cut at the bottom ;D

Hey there...

This looks great :)  Love the use of the shallow CRT and the Dell for the marquee... out of interest, where did you get the CRT from?  What size is it?

Can't wait to see the artwork!

How have your dealings been with https://www.arcadeartshop.com/ ?  I'll need to order some more soon for my rotating cp project... was going to get it from Scott in the states again, but if there's a decent UK company it'll save me some import pennies!

😀 Not as fast as i want to but stuff is happening chap - I've just got to sort my pc out to get photos up.

I've mounted the monitors and sorted out the wiring at the top of the cab (power / marquee LCD / USB ports) so will do a proper update in the next day or so.

Jimbo - I've only exchanged emails with Muddy (arcadeartshop) so far but his quote was pretty good and inline with what you'd get charged in the U.S.  The quality looks amazing though:

Re: The Invaders: 27 August - Mounting the displays
« Reply #58 on: August 26, 2017, 08:50:18 pm »
Bit of a long post this as there's been a few things done. Hope this is proving useful to people, or at least interesting(!). I kinda like journaling the whole thing as it keeps me focused and it's great to get some feedback. I can do 12 hr build videos if peeps would prefer that thoÖ ;). Maybe I'll do some unboxing videos of trackballs or show me walking to a local DIY store buying plastic edging. Yeah.  >:D

Mounting the displays

When i made the mount for the crt i didn't really try to get it too accurate. It was quite a pain getting it mounted without scratching the screen or damaging any of the chassis so i overcut the hole for the screen. When i mounted it into the cab this looked pretty obvious.



So i thought I'd make an inner bezel to cover the gaps and screw holes. The crt is curved so this was a bit tricky but i had the idea that if i cut some cardboard the same size as the monitor frame but made a big hole around the monitor i could use masking tape to create an accurate template.



I then traced this onto 3mm wood that i had laying around (from a previous failed attempt at the front panel!). A bit of work with the jigsaw - and a lot of work with a hand file, i eventually got a semi decent bezel.



Looks good enough for me



TBH i could have just made this out of matt back poster board but i thought I'd use my scrap wood up. In the future I'd probably go that route though as i wouldn't have had to paint it.



Before i put the marquee monitor in i needed to channel the cabling as it would be near impossible to do it with a monitor in the way so i wired up the cabling for the marquee monitor, pc power and external USB ports.





Then added the marquee monitor. This is just some 12mm ply screwed to the monitor using the vesa mount. I didn't paint the ply because a) you won't see it ultimately, and b) i forgot.

1% A, 99% B tbhÖ

And here's a shot from the top. I've added a couple of vents so the the LCD doesn't get too hot.



And that's where I'm up to as of 4 hours ago. A few crappy jobs done but at least I'm not falling over monitors in my spare room now :)

Next job - wiring the tv speakers up and getting the pc inÖ

Artwork is still on hold until i fix my pc...

And cheers for the comments guys - it's a really fun build, but also damn tricky in places so hopefully me documenting stuff proves helpful to someone out there!  :cheers:

Sorry Jimbo - missed your question before. I won the CRT on ebay for ... £1. No ---steaming pile of meadow muffin---. I had a max price on of £50 and no-one else bid on it so I got a lucky break :). It's a B&O MX4000 which is 21". Picture seems pretty spot on and I can use the same remote control as the one I use on my Blip cabinet which is a massive bonus as the remote controls for B&O stuff is ludicrously expensive...

I am curious, how wide is the cabinet? Next to the other cabinet, it really makes The Invaders cab really pop. I wish I had the kind of vision you do. This is one of my faves.

Hi Morton - thanks! The cabinet is 53.8cm wide (50cm wide control panel + 2x18mm MDF sides). It's 180cm tall and 72cm from back to the front of the control panel.

Update incoming...

Time for an update methinks... Essentially the building part is done I've just been a bit lazy sitting down and documenting it. It's still got a couple of things to do, but it's mainly getting the artwork printed and applied and sorting out the software.

Anzwaz - Iíll break this up into a couple of posts as Iíve been doing lots of things and have loads of photos. Starting with:

The control panel

Iíd already created the mockup of this using 9mm MDF so I recreated it with 18mm. Because I don't want joystick/trackball mounting screws showing, Iíve also cut out a 1mm steel sheet that sits on top of the control MDF.

This should show you what I mean: (as usual clicking on the pics will show them at full resolution)



And hereís the controls Iíll be using for the main panel: a Spintrak spinner, a Servostick joystick, 3 goldleaf buttons (Ultimarc) and a 2.25Ē spinner (Happs)



In order to mount the trackball flush, Iíll be supporting it underneath using some scrap wood connected to long screws and nylon nuts. (I've changed the nuts from what is in the pic below)



From the top itís now flush



Customary wiring pic



And final top pic with metal sheet attached



This may be the first time I've wired up a control panel and got the joystick connections in the right place  ;D

More coming soon...

« Reply #67 on: September 14, 2017, 10:01:44 am »
Cheers Opt. I've been getting some good advice  ;D

Speaker / Start panel

Iím using the speakers from the B&O TV which are plenty punchy enough for this build. Because Iím using an IPAC, I can control the volume using shifted buttons rather than wiring in a volume pot for a change. This meant all I had to do was extend the speaker cables from the TV chassis to the front panel.



Iíve used grey speaker cloth in front of the speakers to offer some protection - itís all held in with screws so should be fine. Iíd also painted around the speaker holes with white satin, as this should hopefully(!) tie in with the artwork later.



Finally Iíve added the buttons for Start 1/Credit 1/Start 2/Credit and their wired into a block which is then extended via a longer cable to the control panel. This should give me enough space to work with for when I need to work on the control panel in the future. Iíll probably add some sort of connector to this cable so that it can be more easily separated in future but I didnít have any 5 pin connectors around at the time (and I was impatient!)



And from the inside. It's a bit tight around the trackball/speaker but not too bad.



The end is nigh... so I'm thoroughly expecting something to go wrong...!

Bad news. Good news. Good news.

Firstly, my crt died. I was very upset. Having spent hours decasing/mounting/bezeling the tv it was a massive kick in the balls when it stopped working.

But - Iím an optimist (or at least i hope i am) and managed to pick up the same model from eBay. Bit more cash than i wanted to pay but the picture is better than the old one and i didnít really have many options.

And the artwork is finished and sent to the printers. Iím really chuffed with how it looks now. Canít wait to put it all together.

Not long now...

Itís a Bang and Olufsen MX4000 which I chose because Iím a big fan of the picture quality, and they are ridiculously shallow. The downside (as mentioned above) is that the circuit boards are a bit scary when you first see them as there are about 6 of them all connected together via a plastic cage.
I completely missed that this was a MX4000!  They are supposedly great RGB consumer monitors. We never saw these in North America, but I've read about them from all the UK people who are into RGB monitors. Luckily you found a replacement, but that sucks that another great monitor that could be used for gaming bites the dust.
