C'mon now - it's only been about a year!   ;D

Slow and steady wins the race!  If all goes well, by this weekend I should be all done building with the only thing left to do is tweaking the game lists and a few other odds and ends (mainly the dust washer and getting the ServoStick working).  My son wants some SNES/NES and other stuff so I need to look into "Top 50" console lists for arcade builds... if such a thing even exists.

Anyway, I snapped a few pics while I was working...  Here's the monitor mounting magic:

I used 3M double sided mounting tape.  It has a bit of a thickness to it (1mm maybe) but forutnately the tape is black so you don't see it.



Here's the monitor stuck in place:



Here is the result:



In the pic above, I obviously put this into the cabinet upside down.  One issue I'm having is what to do with the PCB - it just sort of flops around inside.  I've got it temporarily taped to the monitor panel with painter's tape but this won't work long term:

 

I'm thinking of adding some plastic PCB feet and then using either more of the double sided tape or some epoxy to stick it to the back of the monitor panel.  The only concern I have is heat eventually melting the glue causing it to fall... but I don't think it will ever get that hot inside.  I'm going to give it a shot tonight along with mounting the Raspberry pi and iPAC to the back door...   :cheers:

It's funny how vested I become in other peoples projects, almost like I'm in the workshop with them. :cheers:

Home Stretch.  I'm looking forward to seeing it done!

Looking good!

I used extra strong velcro to mount everything in the back of my bartop.  Nothing budges :)

But I know what you mean... you get a lot of cables in there... fitting them all in neatly is a struggle!

Me too!  I'm the same way - there are a bunch of projects around here I can't wait to see finished (yours included).   :cheers:

I thought about using velcro but I had the double sided tape on hand so I just went with it.  I got the PCB for the monitor mounted last night.  It was easy enough - I added some PCB feet to the board and then used double sided tape on the bottom to attach it.  I checked this morning and everything seems to be holding up well.



This is a shot kind of looking straight down into the back of the cab - you can see the PCB with the white plastic feet stuck to the back of the monitor.  I mounted it low to give me some extra room up top because the ipac and the raspberry pi are going to stick out from the back door and into the cabinet by at least an inch.



Unfortunately, the holes in the Raspberry Pi are too small for the PCB feet I ordered - I did some checking and it looks like the holes are 2.5mm in diameter but I think 3mm will do the trick so I'm going to drill them out a little bit by hand and see if I can get the feet attached.  It just makes life easier.



How old is this ipac?  Look at the connector!



Finally here is a random shot from the front looking inside under the monitor.  In all of these pictures you can see the wire bunches I have to deal with.  I may try and cut them shorter and splice the connectors back on.  I'm a little nervous because I don't know what is inside of a USB cable - if it is just a couple of wires then no big deal but if it is like the inside of some CAT6 wiring I don't want to mess with it.



It is a really tight fit inside.  I'm not sure how the CP controls will work yet either.  I need space for the joystick and button wires plus the 2 wires for the servo and the servo PCB.  I hope it all fits and isn't too tight that airflow becomes an issue.  I'm glad I cut out those 3 big holes on the back so that air can get in and out at least. 

So tonight the plan is to:
- drill out the holes in the Raspberry Pi
- mount the Raspberry Pi and the ipac to the the back door
- finish all wiring (other than the CP) if that means cutting and splicing them to fit
- start wiring the CP

You would have a lot more room if you got rid of that wall wart, the plug bar, and all of that bundled up wiring.

I don't really know how to get rid of the power brick or the plug bar.  Those aren't too bad - it's the bundled wiring driving me crazy.  I can probably do something with it if it is just a matter of cutting them shorter and reattaching the USB dongle or whatever is on the end with some solder and wrapping it in electrical tape.  I'll know more tonight when I try to fit everything inside permanently.

Do you have a list of what is being powered in your cab, and what power those devices need? You really don't need all of that bulk in there. If you can work around it that is fine, but we can come up with a better plan if you need more space.

Things that need power:

- Raspberry Pi: Micro-USB powered (5.1V @ 2.5A)
- Amazon Basics PC Speakers: USB powered (5V)
- USB LED Strip Light: USB powered (5V)
- Monitor: Brick powered (DC12V @ 1.0A)
- Servo motor (for ServoStik): Micro-USB powered (5V)
- ipac: USB powered (5V? not sure)

I think that's it.  The pi needs to be powered enough to run the ipac as a "controller", the servo motor and the LED strip light (so that when the pi comes on the marquee lights up). 

The pi, monitor and speakers are currently plugged into the power strip with everything else running off of the pi.  The speakers can just stay on all the time (or if I'm not being lazy, I can use the knob on the back of the cabinet to turn them off) and the monitor is "hot" but only comes on when it is receiving a signal.  It all seems to work (other than the servo which I haven't figured out yet) but cramming everything in is going to be tight.  I already ordered a 18" HDMI cable and a 12" USB cable to try and save space.

To Mike's point, you can use these for example: https://www.amazon.com/gp/product/B01MQGMOKI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1



You just need a 24V power supply with enough amperage to power everything.  Then you take the above and step down to 5V, 9V, 12V whatever you need.  I used them in my control panel.  It would save you a ton of space.

Or just a small 5V power supply for almost all of your stuff, and a small 12v supply for the monitor.

https://www.alliedelec.com/product/mean-well-usa/rs-15-5/70069559/?gclid=Cj0KCQjwjMfoBRDDARIsAMUjNZqMoGHjJyekWjjebk8Lh6wBOENHSKa1R3iwWAGMX5stkccmU-CoY9EaArB-EALw_wcB&gclsrc=aw.ds

There are supplies that provide more current if it is needed.

There are also dual output power supplies 12V and 5V, but I am not sure how small they are.

Thanks guys... this may be a bit over my head without seriously delaying completion.  It makes sense but I'm not sure it is worth the effort unless there is no way to fit everything otherwise.

I mounted the ipac and raspberry pi on the back door and plugged everything in (except for the button wires that go to the ipac and the servo wires) and I think it's all going to fit without any major headaches.  The door closes and I think there is at least some breathing room inside. 

I'll post some pics later... gotta go watch Stranger Things with the fam (everyone has seen it except my son so we are bringing him up to speed before Season 3 comes out on the 4th).

Alright here are some more pics from the inside.

I mounted the monitor control strip to the back of the monitor with a small piece of double sided tape.  It is easily accessible although I doubt I'll ever need to adjust anything.



The next pic shows how I ended up mounting the ipac and the raspberry pi.  I tried placing them in locations where the door would still be able to close and there would be room for cable management.  The raspberry pi was a little bit of a pain to mount but ultimately not that big of a deal.  I had to use a drill bit to make the mounting holes larger so that screws to the PCB feet I bought would fit.  I did this carefully by hand with the drill bit to make sure I wouldn't break anything.  I only needed to widen the hole by 1mm or less. 

I am also trying to run cables underneath the PCBs so they are out of the way.  The braided wire is the power button.  I also found a much shorted micro-USB cable to save on space (the blue wire).  The 18" HDMI cable I ordered should arrive today (way better than the 6' cable I had laying around).



The next 2 shots show the back of the cabinet with the door closed.  On the bottom left I installed the volume knob by securing some ABS plastic to the inside with some superglue and drilling a hole for the knob.  The volume can be completely turned off but I'll probably leave it "hot" even when the cabinet is not being used.  Overall I'm really happy with how clean the back of the cabinet came out.  The hinges aren't too ugly and there is adequate ventilation along with the volume knob and power receptacle. 





Next up is wiring the CP.  I'm trying to figure out a solution so that I can unplug everything easily - there are 14 inputs (10 buttons + the joystick) plus the 2 wires for the servo motor.  Everything will need to be bundled tightly into one wire with some shrink tubing or zip ties otherwise it will be an unholy mess.  I'm sure there is some sort of connector out there I can wire everything into that can be easily separated if I need to do maintenance.   

Probably not going to get a chance to do anything else until the weekend.  We've got baseball games every night the rest of the week (double header tonight).   :cheers:

I've just had very similar issues to yourself trying to cram everything inside. I'd highly recommend using a step down voltage board and only having  a 12v supply into your cab.
There really cheap to. Mine was 5 quid off Amazon.
Unfortunately for me I couldn't get rid of speaker interference, and the only way to stop it was having two separate supplys. So I ended up putting 240volts into the cab and having to cram 2 power bricks inside one for the step down voltage board and a separate one to power the amplifier...

For wiring the cp you could use an atx extension cable. Cut it in half and wire one side to the ipac and the other to your cp.
Then you have easy disconnect to remove cp when needed.

This is exactly what I needed to see.  I probably have a couple of these laying around somewhere too.  Just hope I have one with 14-16 wires.  This seems perfect - I need an easy way to separate the CP from the cabinet in case I need to do some maintenance.

Yes there 20pin. I also carry the 12v supply to the button lights down the same connector so the whole cp can just plug in and out..

Great idea.  My 18" HDMI cable just arrived so I'm going to try and finish the wiring today or tomorrow.  Should be fairly easy... famous last words.
