huw_finney Posted January 24, 2006 Share Posted January 24, 2006 A slow trickle of parts has been comming my way for the DigitalM project, much thinking and designing has been done, much to do. I have put 'mad project' in the title at the request of a forumer and here is a picture of the IBIS4 14mpix monochrome no microlens sensor, true silicon porn if ever ther was any...<div></div> Link to comment Share on other sites More sharing options...

Brad_ Posted January 24, 2006 Share Posted January 24, 2006 Which ADC you using (and clock rate). And 1 or 2? www.citysnaps.net Link to comment Share on other sites More sharing options...
huw_finney Posted January 24, 2006 Author Share Posted January 24, 2006 Brad, The LTC2884 dual 14 bit, two of them as this chip has four outputs. Using this ADC I can shift the DCs of the sensor and ADC and the range of the ADC to remove the need for extra amplifiers/DC offsetters. Working at 10Msamp/sec as recomended by the sensor datasheet. Other chips are an Altera EP1C6 144TQFP FPGA to do all the clever stuff, a Micron tech MT46V32M16 dram for 'burst' storage, and in the end being put on a MMC Flash card.<div></div> Link to comment Share on other sites More sharing options...
roger_michel Posted January 24, 2006 Share Posted January 24, 2006 why does a compay make a 14MPIX monochrome sensor? what is the target audience for such a device? Link to comment Share on other sites More sharing options...
benjamin_shapiro2 Posted January 24, 2006 Share Posted January 24, 2006 I know little of this electronics stuff, but why MMC? Link to comment Share on other sites More sharing options...
benjamin_shapiro2 Posted January 24, 2006 Share Posted January 24, 2006 Also, when i read of this business with the rock in Russia, I thought of you. Link to comment Share on other sites More sharing options...
Brad_ Posted January 24, 2006 Share Posted January 24, 2006 Huw, do you really mean the LTC2284 (a typo)? That's a very nice device, designed mostly for cellular basestation digital radio use - but should work great in your app - the low power dissipation being a big bonus. If you're only clocking at 10 MSPS, consider the LTC2295 - similar device, lower clock speed and much lower price. 120 mW at 10 MSPS. www.citysnaps.net Link to comment Share on other sites More sharing options...
huw_finney Posted January 24, 2006 Author Share Posted January 24, 2006 Roger, no idea but I am pleased they do. Benjamin, MMC has no license issues, unlike SD. The rock, like it! Brad, the LTC2284 or somesuch I have got the 25Mss one whatever that is, I always like a bit of headroom and at 25 bucks a piece not bad. The annoying thing is I had to get all the (special) parts from non UK suppliers (3 USA one Belgium) and hence added quite a few bucks in Fedex/DHL charges.

laptoprob Posted January 24, 2006 Share Posted January 24, 2006 Wow, promising! If I get it right it should be possible to build this into - basically - any camera? As long as you can get to the film plane? When developed into something practical, that is... Rob Link to comment Share on other sites More sharing options...

vivek iyer Posted January 24, 2006 Share Posted January 24, 2006 Kodak made a few of the B&W dSLRs for lots of $$$$$ and on special order. They might have sold a few dozen of them, I think. Link to comment Share on other sites More sharing options...

jonas_yip1 Posted January 24, 2006 Share Posted January 24, 2006 Definitely a cool project. I wish I had the know-how to tackle a project like this. If only I had a degree in Electrical Engineering or something... oh wait, I do! Still wouldn't be able to tackle this though. I look forward to the updates... j Link to comment Share on other sites More sharing options...
