Eventually I'll redo the video a few posts above because the PQ is low resolution due to editing the video on my phone. However, I have another good example of GI OCD in action. I made a video of my garage and have a part where I show what Demolition Time looks like with GI OCD.

If you check it out, fast forward to 7:30 in for Demolition Time. There's actually some LED OCD in the video, but I don't do any before/after comparisons.

I put the GI OCD in AFM and was blown away with how much better the machine looks during gameplay. Finally I can enjoy the fading/dimming as intended by the designers while also using LEDs. I still have not tinkered with settings but as they are set stock seemed pretty darn good to me. Installation was a bit tight but the end result was well worth the money and effort put in.

Thanks for making this for us pinball addicts out here Herg!!!

Personally, I'm upset at Herg. He puts out a good product. He's given me another reason to go broke. (furiously updating all machines for LED and OCD).

First, let me say the difference is extreme! The GI OCD is a great product. I installed this on my JM this morning. The installation was straight forward. Be mindful of angling the PCB so you can insert the USB connection into the board (mentioned earlier). I had to angle mine away from the speaker panel backstop in order to have a clean connection. Other then that installation both for the software and hardware took less than 15 min. I have played with the settings and they are exactly as advertised. Please read Herg's software usage page carefully, it provides everything you need to know to get up and running. Now to the only concern I have. Now I get a distinct whine (high pitch) from the GI. Does anyone know what would cause this? It was not present before I put in the GI OCD. Any tips would be helpful.

Herg. I just spent about an hour adjusting, replacing LEDs, tightening, moving cables.... well, it worked! It went away. I adjusted the speaker wire locations by moving them away from the GI cables as you suggested. Thanks again. This MOD is a must have for the GI dimming! Can't recommend it enough.

Dragging this thread out again for a question on it..

Does this also smooth out the flicker you get when the solenoids are firing on some games?

Harold's a genius. I may not be- I'm having trouble understanding exactly how I should adjust my GI OCD in my TOM. Just installed it a few mins ago and tested a key dimming effect- the multi-ball start-up. The flicker I experienced before (I've always had LEDs in the GI and just dealt with the flicker) is gone, hooray- however, with the default settings on the GI OCD, it doesn't appear to have enabled for any dimming. Can Herg or someone else lay out a good settings synopsis for TOM ?

Did you go into the game's menu (not the GI OCD but the actual game's menu) and turn on the dimming? A lot of times people turn it off when they install LEDs.

I wonder if GI OCD would make a difference on my Roadshow? Do not know if any dimming is used on that machine?

You can always go into setting and look to see if GI dimming on/off is an option.

Most machines that do have GI dimming, simply use it during long periods of inactivity. Some machines like STTNG, TOM, TOTAN to name a few use it a LOT during gameplay.

GI dimming should not be confused with turning off the GI during game play via a relay, like a lot of System 11 and older do.. GI OCD will not help with that.

The option is there but I never noticed any dimming while playing - I must admit that I immediately switched to LEDs after buying the machine. Maybe when Super Payday starts but the GI (all LED) is switching on and off in a way I like very much. Would be interesting if it looks different with regular bulbs. Maybe other RS owners can bring some light into this?

On my STTNG I solved it easily - simply using 906 bulbs for the shields. Tried the shield with cyan LEDs - but as the shield strenght is not indicated with LEDs I reverted to bulbs. All other lights (Inserts and GI) are LEDs. Beside the missing dimming of the backbox I did not notice any drawback. Or is there any?

Nevertheless the LED OCD would really be nice as I do not like the hectic blinking of the Inserts with LEDs. Does it work in european machines with 50Hz?

Ok, as I do not see any flickering of the GI on both of my machines (at least I do not notice it), I would only be interested in the LED OCD. Is there a preset or is it absolutely necessary to adjust it with a PC connected? Would love to have a plug and play device!

I'm all set- it was string 4 and string 5 of TOM set to always on.

now onto fine tuning the five strings !

Excited. Just ordered GI OCD for BSD! The colored GI lights look awesome but the strobing is an instant headache. Can't wait to install that GI OCD and smooth that out!

Keep in mind you have to go into your menu and turn the dimming "ON" first, then look for flickering in the GI. I suspect Roadshow has some dimming based on the year it was put out, although I'm admittedly not that familiar with it.

Pretty sure GI OCD is preset for 4 and 5 always on. Which is oK in a T2, but in a STTNG/TAF/DemoMan etc,,, they use GI 4 and 5 for 'show' so you have to change the default.

I can't believe people don't find this board a necessity. There's a profound amount of flicker with GI dimming enabled - or maybe I'm overly sensitive to it. Will definitely be adding this board at some point in the future.

I replaced every GI light in BSD with non-ghosting SMD LEDs in blue and some reds. The game looked awesome, but it was an absolute nightmare of strobing. Just looking at it gave me a headache, let alone trying to follow the ball with the strobe light effect. Two days after installing the LEDs, the GI-OCD finally arrived in the mail and I installed it. The difference is like night and day. There is no strobing at all, just like real light bulbs and the game looks amazing. The difference is profound to me whether there is dimming or not. LEDs were simply not meant to run on A/C power.

Were it not for the GI-OCD, I would have to pull every single LED out of this machine despite how cool they look.

i think a lot of people have GI dimming disabled and don't realize they are missing out. The strobing was just ridiculous on my STTNG and my Funhouse at certain illumination levels. GI OCD completely cured it.

GI OCD ordered--looking forward to seeing what it can do on a DH. There is a lot of GI dimming, should give it a workout.

Got one for Congo and another for Twilight Zone... Yet to fit.

Great product, but a major pita to program if you are not a PC person. Took me at least an hour to get everything downloaded--actually find it where it was buried on the PC (Mac just woulda popped it up on the desk top), then download the missing drivers, then figure out how to make it work. However, it sure tames the flicker and strobing! Very much recommended!

It was not relatively easy, and Windows 7 did not automatically download the drivers for me. I also had difficulty downloading the GI-OCD program, but finally got my borrowed PC to agree to do so. Anyway, if I had to do it again it would be a lot easier. I still don't like PC's...

Reviving this thread from the dead to ask again if anybody has found a way to restore chasing lamps on CFTBL since we last discussed it...

Such as this thread where I was trying to run a KBOP mod off an GI OCD.

Does anyone know of any mods that don't play well with the GI OCD or LED OCD boards?

I own a Judge Dredd so far I've used the GI OCD board with no problems but I am concerned that when I install the LED OCD board that it might interfere with my sparky micro display mod?

Any thoughts or first-hand experiences?

did you ever answer this question?

Thanks. I had done the same (OCD?).

They're using LEDs in the inserts, so i wouldn't be surprised if the GI was LED too. As such they may have disabled GI effects.

I'll see if i can find any incandescent Roadshow videos.

Not much, but a bit:

Absolutely LOVE this product in my TZ. Makes the game look absolutely beautiful

Does anyone know if there is GI dimming used in either Doctor Who or Monster Bash (or TZ for that matter)? I would like to add one of the GIOCD boards but have to keep the budget in check. LEDOCD is already going in...

also, herg: I'm sure you've considered doing a single version which incorporates both LEDOCD and GIOCD; is this feasible?

TZ uses a LOT of GI dimming in the gameplay.

Very interesting... that's exactly the sort of detail I was wondering about. Guess I'll have to order at least 2 of these.. damn you, Herg!!

I just installed the GI OCD in my STTNG. I installed LEDs almost immediately after I acquired the pin, so I didn't really recall if the GI had any dimming effects, but from what I can tell only the Shield inserts make use of dimming. Granted, this is really cool when you're in Borg multi-ball and the shields take hits, but I'm not sure it's worth $160 for that one effect. I'll most likely switch the GI OCD over to my DM. And regardless, the build quality of the product is fantastic and well worth the price.

That's one thing that's cool about these 2 boards - you can put them in nearly any game you want! I've had trouble spotting the GI on some of the games I've tried it in. It landed in my TZ where I expect it will sit permanently.

I may try it in my Monster Bash, too - I fully expect to put an LEDOCD in there eventually.

On STTNG the backbox also dims during some modes (video modes, maybe others). Pretty flickery even with incandescent.

Good choice. It's awesome in DM.

Finally installed my GI OCD board in my Johnny Mnemonic. Highly recommended with JM as there is a lot of General Illumination dimming during game play. Now to install the other one I have in Dredd - Blackout Mode will be so much better.
