This blob thingy...Its very strange. I have a DSI-setup in the building/testing/getting-extremley-frustrated-stage. Kind of like yours, altough not as clean and well built. Since i got to little children that i want to use the table i havent been that strict in the looking-good-part of my table.
I got, right now anyway, the following setup;
This is about 32 “ in diagonal - made for a 32 “ lcd at first.
Plane glas - 6 mm (no scratch = good kidstable) and i dont think the risk of braking the glas is a problem because its resting on the endlighten…
Cover plastics ( dunno the english word for this but i use it for testing projectorimage and stuff. its a semitransparent plastic sheet with about 0.1mm thickness.
endlighten 8mm with around 95 osrams surounding it
Ps3 with ir-filter for 880nm - sort of bad focus altough i think its the best i can get at the moment.
As i wrote before i started my table for lcd but have now gone over to projector, atleast for the time beeing. This is cuz i did not get good blobs thru the lcd matrix, well actually i did a couple of times but not in the long run, wich is kinda strange. I have been testing this table for a couple of month now and just when i seem to get somewhere it just stops working. I have had good blobs with the coverplastics and projector fired upp, Just touching the glas gently. but then out of the blue i dont get none. And if i turn values higher you can see some blobs blinking. Kindof like the camera running wrong hertz or something. I dont really now. The main thing is i have had gooood blobs and calibrated and run some programs, got a bad framerate (15), tried to change it and then it stoped working.
Damn i feel like im 6 years old and trying to write english for the first time. ( Yes we (try) to learn english from 6 years in sweden. No good explanation, i know. I will try to get some videos of this dilema i got. And others with me.
Oh, when i got my setup working i noticed that its pretty sensitive to sunlight. Would sunscreen, you know the type you got on your carwindows, work as prjection image AND blocker?
Hmm..i got a project-thread in here somewhere....guess i outha dig that out here…
Gotta work some for now....
