hmmm. i have to admit, i am not sure what you are talking about? what is 8.3 file naming? i even tried "CINE221.bin", "cine221.bin", "blah.bin"... still not accepting the file.
i even typed in the directory in the edit box - wont reveal the upload button still.

after speaking with dummyload regarding the modified bin file i decided to at least try flash one of my 909's. i cannot for the life of me get it to enable the "upload" button when selecting the bin file. i poured through all the threads on here and even the flashing pdf by hulio... i renamed the bin extension to lower case and it still wont enable "upload"! what am i doing wrong?
it keeps giving me an error message saying "file must be extension *.bin !" - ridiculous. the file is "CINE221_EDIT.bin"...
that program is buggy and incomplete.

sent you a pm dummyload.
case: i had a quick snoop around the other data. without flashing it to a machine to test, i am not sure what else i can change. there is significantly more data in one of the bin files compared to the others... i would have to study the files carefully. but anything is possible.

just a quick reply. dummyload - I modified the binary data where the skyskan text and a few other areas were. I am 100% it will work, just need to flash my 909. I am waiting on another part to arrive before I do it. I wanted todo a side by side comparison of my modified 909 next to a stock 909.
I can send you my program or edit the cine 9 bin file to say whatever you want?

I reread what I wrote and it does sound confusing. sorry!
yes, youre right. I wanted to mount it directly behind the fan (about 25mm away) to deflect the air.
after some more thought I will go back to the drawing board on this. I didnt like the way I had to mount this backing plate to the fan, either... its too fiddly.
I dont want to drill out the box on the back of the 909 (I dont want to drill or cut anything really), but it would be so much easier if I did.

i got lazy. i have three designs for a rear baffle similar to the cinemax/cine 9. the easiest was this drawing: ^ the plan is to mount this backing plate to the rear section of the fan. studying what barco did on the cinemax/cine 9, they only tried to block direct fan exhaust into the rear perforated grill... i am optimistic that this will achieve similar results? i will use a spacer between the plate and the fan on each bolt hole. i will fire the set back up once everything is fitted.

thanks case. im sure it will yield some type of improvement? i was going to do a side by side audio recording of a stock 909 and my acoustically modified 909 before firmware flashing to get an idea of improvement. not sure if i can capture this accurately however, as all i have to record with is a mobile phone. hearing it with my own ears will be the true result as i eventually plan to sit underneath them. i did try other materials with the new drawings. one of them was hdpe and was horrible to machine. it required cleaning which i didnt like, unlike wood. wood machines nicely. i setup the cam speeds for my block of billet aluminium in fusion 360 and it was estimating 65min runtime... per baffle! and i need 6... at those speeds, no thanks the stock i had was 20mm thick as it was all i have laying around spare. if i had 12mm thick stock, it may half the time. but as suggested above, wood has some absorption properties that aluminium does not. i'll be machining the rear plates today sometime from spare wood i have laying around. however i dont have bolts thin enough to pass through the holes of the grill to hold them up. anyway, i will report how it turns out later tonight...

small update. i redesigned the original drawing. the reason for this was the material i decided to use for the final parts is wood. the original drawing had thin walls. barco used aluminium and its far more rigid than wood. after a few test cuts, i was happy with my final design: ^ each fan baffle has its own drawing unique to its surroundings. the pcb's clip into the aluminium near the fan mounts and create protrusions that prevent a flush fit with my original drawing. i now have cutouts to prevent this and now get a perfect seal on every fan mount! all thats left to do is mount these with some rubber nuts i found from a local supplier: ^ these are very similar to what barco used on the cinemax/cine 9's. this will allow for some vibration absorption and easy dis/mounting of the fans for servicing when required.
^ these are just sitting freely. i have not purchased the rubber nuts yet. my next part to machine is a split rear baffle for the perforated grill on the back panel.

out of curiosity, what do these liquids do to the c element seals? whats the life span of these seals? these types of things are not produced anymore. like the marquee bellows i imagine they need to be re manufactured by someone?

the only material that I could comfortably machine other than wood and aluminium is perspex or hdpe. these are both somewhat hard plastics? this is the cine 9s fan shroud mounted. barco used two small rubber bits to absorb vibration. they sit 2mm~ off the chassis? the 909 as casey said uses a rubber bolt to hold them about the same distance away from the chassis. my 909 rubber bolts are tired. I will order some hdpe and see how it turns out. should machine okay.

hello all, i wanted somewhere to document some of the modifications i plan to do to two br909's i've just purchased. these sets have firmware installed that has the rear fans run at full noise from power up. i understand that simply flashing them with the cinemax/cine 9 firmware will reduce fan noise and i plan to do that, but wanted to replicate what barco did with the cinemax/cine 9's sound baffle on my cnc hobby machine. ^ on fusion 360 i drew this for machining. it's a close replicate of barco's fan shroud. i only have a 6mm wide cutting bit, so the bolt holes are 2mm wider. ^ out of some mdf (cheap wood) i had laying around the garage i test cut the drawing to confirm measurements. it's perfect. ^ the wood is weak and the narrow wall is flexible. i plan to machine the final parts from billet alumnium, so this will not be a problem. ^ with no nuts fitted, i test fit to make sure everything lines up. perfect! i also have drawings for a two part board to cover the rear perforated grill to reduce noise further. i made a bracket to relocate the power filter where barco have it on the cinemax/cine 9's. i will post pictures as the parts are completed. regards, justin.

does anyone know how we came about acquiring these files <CINE221.bin>, <Cine213[1].bin> & <EKU222[1].bin>? did someone pull them from their boards? i noticed in one of caseys photos theres a page that has "SkyVision" etcetera.
i quickly got looking through the bin file just now and discovered how the tile data is stored to draw these specification pages on the projector.
i wrote a small C++ program that reads in the bin file, modifies this data and rewrites the file. the file size stays the same. there is no overflowing data. it just replaces the tile data.
what this means is: i can replace everything on those pages. from the logo, to the text. even the text for "PROJ. ADDRESS", "SOFT. VERSION", "CONFIG." etcetera with anything you want (a-z, A-Z, 0-9). even colours it appears.
i cannot test this as i cannot find an RS232 cable in my cable bin unfortunately. so it will have to wait.
what i plan to do is flash both my 909s and change the "SkySkan" page to have the Barco logo and below that have "JUSTIN'S BR_909 STACK".
i can post more details on my findings if anyone wants. i plan to rewrite the program to make it user friendly and available to all to alter these fields without accidentally spilling the tile data in other data.
regards,
justin.

hulio: thank you! i appreciate the prompt reply and follow up. i am going to download and store all the barco 9xx series files from this website on my google drive for future safekeeping... in case anyone comes across this post and the files are unavailable. just contact me through here.
i have spent the last two months reverse engineering binary data files and have gotten pretty good at finding storage patterns. i am going to have a look around the bin file, but only with the intention of being a sticky beak at this stage.
gregstv: hello greg. i am curious what you mean by your comment? i should elaborate what i am trying todo with this program. my intention is to slow down the fan speeds of the 909s?
i did see on here a thread with a list of capacitors for different boards. i will run my eyes over the list today.
regards,
justin.

hello,
just wondering if anyone has a copy of the barco explorer program they could please upload or email me? the one drive link in the stickys is broken...
I want to flash a 909 with the cine 9 latest firmware. where can I get a copy of that bin file also?
thanks for your time.
regards,
justin.
