Going to use jomac for the parts to run to a arcade card. Monitor was just a rough in so i can get it in the right spot . Question. I dont know how i am going to use to cover the screen. I have a 4cm gap from the max front of tv to the front edge. I asume i will use glass . I dont know how. i can router a edge, for it to side in but i cannot side it in. Ideas or comments please :rolleyes Edited October 18, 2010 by DirkDiggler Link to comment Share on other sites More sharing options...
Big Giant Head Posted October 20, 2010 Share Posted October 20, 2010 Looking great mate! For the surround you could always use some MDF with the cutout angled with a router? You'd probably have to build a bit of a lifting frame to match the depth but painted black with glass over it could look pretty shmick. Link to comment Share on other sites More sharing options...
DirkDiggler Posted October 20, 2010 Author Share Posted October 20, 2010 (edited) done a few more things. wife gave me a few ideas. Doing control pannel atm. Going 2 joysticks and 6 buttons each. 1 and 2 player. But i want to add a few control buttons. Like pause and stuff. I have not used the mame software that much. So not really sure how many controls there are.. But i am only going to add 3 max. Pause is a must but. With the glass. I have read here about it. Most people say glass with a 5 per cent tint. Correct. ? If so where can i buy it from. Any glass place? Live in wetern sydney, What about speakers. i have a volume control knob hiding outside to adjust that. So i need computer speakers.. Looking at something like this maybe http://www.arc.com.au/pub.php?gid=23377&pid=35869&p=product Ideas Edited October 20, 2010 by DirkDiggler add stuff Link to comment Share on other sites More sharing options...
Big Giant Head Posted October 20, 2010 Share Posted October 20, 2010 With MAME there is no need for a dedicated Escape or Pause button. The Player 1 start button acts as a Shift key so hold that down and tap down on P1 joystick for pause and for Escape hold P1 start and tap P2 start. There are other controls accessible via the use of the shift button but those 2 are the most commonly used. 2 player 6 buttons each sounds like a good plan (it's what I have on my upright). As for glass I have tinted perspex on my upright and tinted glass on my cocktail, glass is slightly dearer but really does look sexy. With the perspex I have a slight grey tint and the glass is a slight blue tint (grey was out of stock lol). You should have no trouble getting it from a local glazier but do get it toughened for safety and durability. Incidentally the perspex and glass are both 6mm thick. For speakers I have an Altec Lansing sub plus 2 high end car stereo speakers and the thing pumps! As for volume knob, mine is located inside the control panel.

Woody Posted October 21, 2010 Share Posted October 21, 2010 I have always used inkscape. Make the canvas the size you need then just zoom to fit screen so you can see what you are doing. Link to comment Share on other sites More sharing options...
lien_Zed Posted October 21, 2010 Share Posted October 21, 2010 can u show us some more pix of the inside. just concerned u may not have enough cross bracing. nothing more heart breaking then building a cabinet then try and move it and it falls to bits infront of your eyes and all your hard work is destroyed Link to comment Share on other sites More sharing options...
DirkDiggler Posted October 21, 2010 Author Share Posted October 21, 2010 back pannel and cross bracing is not finished yet. Need to get a friend to go to hardware shop .

DirkDiggler Posted October 22, 2010 Author Share Posted October 22, 2010 trying for find speakers.. i saw that some people here go or a amp then car speakers... http://www.audiovisualdevices.com.au/viewprod.php?catid=&productid=APC554 is what i have bought so i can put it on the top of arcade unit where no one can see but i can adjust the volume.. Been looking around for some good quality speakers but all of them have this power on/off on the wired remote.. which i dont want.. So question.. is there a amp i can buy which can connect through a 3.5mm plug to this thing i have bought and then i can connect to car speakers. I was/am trying to go for a 130 dollar 2.1 setup that had a very good amp..( wanting if i can hack it do when main power turned on ... speakers/amp turns on too..auto Link to comment Share on other sites More sharing options...
Boddah Posted October 22, 2010 Share Posted October 22, 2010 Most amps should be able to take RCA inputs, so you may just need to grab a 3.5mm to 2xRCA cable. Just take a close look at the input specs for the amp. On mine the RCA ports are for low level input, so my amp is actually turned down to nothing and the main PC volume usually only sits around 4%, so just be mindful of things like that so you don't blow your speakers as soon as you turn it on.

DirkDiggler Posted March 28, 2011 Author Share Posted March 28, 2011 (edited) update. done a bit of work here and there. i have the following marquee ..

Do i need a grill or something so sound goes outside to the side? Edited March 28, 2011 by DirkDiggler added stuff Link to comment Share on other sites More sharing options...
adz_78 Posted March 31, 2011 Share Posted March 31, 2011 I am pondering the same question with my sub. To my understanding (someone please prove me wrong if I am!) base is not a 'directional' sound and can be pretty much placed anywhere. I imagine for a cleaner sound, and one that is not going to rattle your cabinet when you crank up the base, then the speaker should be facing the outside. If heavy base is not your thing, then I do not think it matters. Advice from someone who has done this?? Adz Link to comment Share on other sites More sharing options...
Woody Posted April 1, 2011 Share Posted April 1, 2011 The sub in my cab is just mounted inside with no opening. It pulls enough air in and out through the fan grills and vents. Link to comment Share on other sites More sharing options...
pinnieroom Posted April 2, 2011 Share Posted April 2, 2011 I've built a couple of cabs with subs inside and no grill. They sound pretty good as they are. You can always cut a grill in later. Link to comment Share on other sites More sharing options...
TheWiggman Posted April 11, 2011 Share Posted April 11, 2011 I've built a heap of car and home subs in my time and putting the sub inside the box won't really make a difference. A common myth regarding ports on subs is that they allow the speaker to 'breathe' - not the case, they (in a sense) provide constructive interference from the rear of the woofer to make the sub more efficient. There doesn't necessarily need to be a gap in the cab for the sound to get out. For a sealed woofer or similar the sound isn't directed from the woofer as such, but it's as much the enclosure that makes the noise as it is the cone itself. Mounting it inside the cab won't cancel much sound either because of the length of the sound waves from subs. Lower frequency = longer wavelenths, and matter in general is far more effective at cancelling short wavelengths than long ones. When a car with a big sound system goes past you the bass is far more prominent that the treble for this reason. adz_78 was spot on with his comment about bass being 'unidirectional'. On my cabinet I've mounted the sub into the actual cab itself, and it's very loud and clear from the outside. Unless you're using a really small sub that can't hit low bass (let's say <50 Hz) then I don't think you're going to have any issues mounting it on the inside. Just ensure that everything that's loose is fastened down. Link to comment Share on other sites More sharing options...
