Quoted from harryhoudini:

Like a 2d vertical piece of plastic with a decal on it?
I think I'd rather go like the "beach scene" with some treasure and palm trees. Doesn't that jive with the treasure chest?

Quoted from KornFreak28:

IMO, anything you put there must be proportionate to the chest. The chest is huge and if you add tiny palm trees or tiny rowboats they will look out of place. Why not add some gold or something along those lines? Or just hide it with decal. Less is more IMO

Quoted from harryhoudini:

Gold = treasure/loot, that was one of the ideas.
Row boat would be as big as the chest but only about the top half of the boat.
I don't think an out of proportion beach scene would look out of place, it would be more like forced perspective (think cinderella castle in disneyland).
Working on some options, we'll see what looks good. I'm partial to the loot option but I'll likely print at least the row boat to see what it looks like.
If less is more, a black box would be the ideal one. Hardly visible, no lights really shine on it. I think we'll offer the box as a base and then a topper of your choosing.

Quoted from JimWilks:

Given that I seem to be the only one with this problem and 50+ other (successful) installs of this mod I think my problem is one of:
A) My game has an abnormal 5V level at 4.65V
B) I have an abnormally sensitive (to turn on voltage) Arduino Nano
A lack of other games and a lack of additional Arduinos make both of these difficult for me to confirm. Perhaps other owners can measure theirs?
In any event, I need to get this mod working. I've ordered the the following which should do the job:

Quoted from JimWilks:

Got the boost regulator. Boy is it small!
[quoted image]
Installed it and mod is working fine now.
Sorry for the pic being out of focus, but you get the idea of size relative to a dime.

Quoted from Rdoyle1978:

I think I may have this same issue! I did not order Scott's mod, but built it myself - I am following the exact connections, code, and setup as Jeremy's original setup, plus a couple of changes I've read about in the thread - and I'm getting basically the same behavior.
The servo moves a bit when first powered on, but then after that it just sort of hums and I hear an adjustment move here and there, but nothing occurs when the switch is triggered.
I haven't worked on this mod in a few weeks, having started on a game restore, but I went over everything today - switched to another Nano, even. Same behavior. I have not checked the debug log yet, so I will do that next and make sure the switch is being registered. Bummer, this one!

Quoted from harryhoudini:

Have you plugged it in to an external power supply? That would give you a clear indication if it was a power supply issue from the game.

Quoted from zaphX:

harryhoudini I'm installing one of these for a local friend tomorrow. The only thing I am unclear on is the removal of the existing lid, does this require Pearl removal?

Quoted from KornFreak28:

He posted a really cool video on his site. Pretty easy IMO.

Quoted from zaphX:

I must have missed it. I reviewed the install instruction videos which started with the parts and ended with the alternate rod setup. Did not see one for the initial chest disassembly?

Quoted from KornFreak28:

Look at post 826

Quoted from paynemic:

So I reprogrammed my Arduino with the new code. Went reasonable well. But now my chest opens all the way then closes most of the way (when it should be wide open). Did I miss part of the instructions? Is there a homing routine or do I need to change something mechanical?

Quoted from PinMonk:

Are you using the star arm on the servo? If so, you probably have the rod on the wrong one.

Quoted from harryhoudini:

Are you saying this happens when it first turns on? It does a new startup routine yes, it cycles the chest once. It should go the same distance it did before the update (I don't think that changed). I think the direction should also be the same on the new version, which is why there was a non-versioned update to 1.1 (which I think only one or two people downloaded). Did you move anything hardware wise when you did the update? Like, take the whole thing out and put it back in? I would only question if the rod is binding on the lid (in the hole) and needs a little bend. Unless it's hitting something else that was really the only reason I saw for partial movements, that or the rod not being aligned/adjusted. But if you didn't move anything that would be odd.

Quoted from Rdoyle1978:

Also, having gone through all the assembly, troubleshooting and purchasing of the raw materials, I want to wholeheartedly say that I think scott’s price is INCREDIBLY fair.

Quoted from zaphX:

harryhoudini Ive installed the chest mod for cheshirefilms and it seems to work perfectly except the state is inverted. It closes when it should open and vice versa.
Does flashing the software fix this?

Quoted from PinMonk:

Putting the rod on the opposite arm of the servo also fixes this.

Quoted from zaphX:

Thanks for this tip! That fixed us. The only other hicky was inconsistent operation at first, corrected with a slight bend to the switch arm.
The mod is cool!

Quoted from BC_Gambit:

Agreed. After receiving the kit from Scott I think he is undercharging a bit. For sure now that the code should be settled and with maybe a few tweaks as suggested to the install videos.

Quoted from paynemic:

I did take some slack out of the rod (I know better than to adjust two variables at once, but I did it anyway). Before the update, the nut was maybe 7mm above the lid plastic when the lid was closed. So I kept it closed and took that slack out of the rod and retightened. Now it opens all the way and then mostly closes again.
I’m a little confused about the version I should have downloaded. It’s my recollection I did download 1.1

Quoted from Rdoyle1978:

Got it!

Turned out to be bad code, I think. Or perhaps the additional LED code (I have not added the heartbeat LED strip)
Once I reverted back to Fleitz’s latest .ino from github, it worked immediately. Weird! KILLER MOD!

Quoted from harryhoudini:

Sounds like you got it Glad to hear it went relatively smoothly.

Quoted from zaphX:

It's a great mod. After seeing it in action, the game seems so broken without it.

Quoted from harryhoudini:

Sounds like you got it Glad to hear it went relatively smoothly.

Yeah, I have those videos open in FinalCut.. just need to do it. We had no idea what we were getting in to, lol. I owe my wife big time for doing a lot of the soldering and production. It was a good learning experience and gave us a push to make more mods, so all good.

You're good. I had an early version of 1.1 where I changed the rotation direction and that got confusing. Right now all the code versions go the same direction, it's just my video that is wrong.

If you used the code I posted there are some changes, I think, to the way pinballj had his connections laid out. I could look at his prototype and compare if you want to know. I can post a pic of the controller wiring and such laid out if you want to duplicate it.

Quoted from Rdoyle1978:

Thanks Scott - I didn’t think to check. I’ll read through the updated code. Were there further updates? There are only 5 connections to the board for the servo mod, so I’ll just read through the .ino more carefully. I thought I checked the servo control connection (which I have wired to D10), but I didn’t check the switch connections.

Quoted from harryhoudini:

Here's a pic.
D10 servo white wire
D3 is lighting DIN green
D2 Switch red
D5-D8 keypad controller
Ground IN from game goes to switch black, servo black, lighting black, GND on board
Power DC+ IN from game goes to servo red, lighting red and VIN on board
Power DC- IN from game goes to GND on board

Quoted from Nepi23:

I have installed the mod today, but for some reason the chest does not seem to open or close...
I have followed HarryHoudini's instructions, but still it does not seem to work for me.
I attach some pics - where to start to diagnose, what went wrong?
Also in my installation the bracket touches a bit the clear plastic piece that apparently is there to protect
or to ensure no ball locks would take place. I draw a yellow arrow there. What have you done, have you
removed it altogether?
Thank you for any help![quoted image][quoted image][quoted image][quoted image]

Quoted from Nepi23:

Only the rod moves and the chest a bit. Have a look here:

Thanks for the tips!
Rotating the 4-wing arm 180 degrees did the trick. Now the lid opens and closes correctly.
The leds are glowing yellow color, I guess that is correct and they will display red at some other time? Or should I adjust the color to red as a default?
There seems to be another problem developed now though. Treasure Chest multiball does not seem to be able to start. Have a look at the video:

Any ideas what the correct here? Thank you![quoted image]

Quoted from PinMonk:

Either you accidentally bent the release arm away from the tiny coil a little too much when installing the hinge bracket (you can bend it back a little more towards the coil post so the coil can "grab it" and pull the door flap open) OR you need to increase the chest release time on the system menu so it holds the flap open a little longer.

Quoted from Thot:

I had this issue Yesterday without this mod, balls seems to be magnetized. I actionned the release coil by test mode and finally release balls. Next game had good work

Quoted from harryhoudini:

Yup, that's another common reason. Can't use chrome balls, apparently.

Quoted from KornFreak28:

What kind then?

Quoted from harryhoudini:

Chest mod doesn't open and close with the game but goes through the open/close cycle when you power it on? Likely your switch needs adjusting:
