Hello everyone, Here are the 1st real notes on the CCD back process... and also some test for folks around... As it is now, I think this will be the last email here, those who want to be kept in the wheel ... well express yourself, I will try to send the main list some milestone for the major info as when the spec will be frozen and ready for finalising, then proto, then the rest. I think this can be done nicely and fun. The schematics/layout/software should belong (my suggestion) to those who put work in it. We already have a software guy that raised a hand (hurray), We would need a mecanical designer... We would also need an Opto guy , for possibly make a simple correction lense... and more than one each is always better =) Mainly the current part list is for starting the process, parts will be changed and adapted until the functions can be provided Also other brand have asked to join making this more possible project... Philippe PS: stop talking, start doing ----------------------------------------------------------------- CCV V0.11 V0.1 first release V0.11 CCD Philipps FTF3020C, Altera EPF8282ALC84-4 (processor) ------------------------------------------------------------------------ Problem: -2.4mm from the top of glass to ccd sensor... -Sensor will be further than normal film, so we will lose infinity... Solutions from best solution to worst: -Find another sensor or custom make one ?? -Make a corrective glass on the sensor ??? (not my beer, but if someone is good there... let's talk) -Use AF lenses as they can focus past infinity , but how much will it give -Use a weak home made Teleconverter... -Use a smaller apperture this is not pretty but working +/- -Machine some part of the frame ?? ouch -Make a complete K mount frame from scratch using mirror box from certain model (if we find a mec designer) -Remove CCD glass then the chip frame to CCD goes down to 1.3mm instead of 2.4mm -------------------------------------------------------------------------- Actions and Testing: -Take a AF lense and see how far is the lense going at infinity -Query price of sensor (Called Philips Europe waiting phone call) -Query price of LCD -Query price of small bits and pieces -Make part lib -Make 1st layout (in process) -Make price study of current BOM (see below) -Find a full frame lower res sensor ? ----------------------------------------------------------------- Functionality: -Back Custom made Back for various frame LX (3) MX (1) PZ-1P(2) Leica (1) total 6 goal for 1st batch 10-15.. -Power supply 4 AA external batt pack -Mass storage Compact flash Type 2 (up to 1Gb and more later) -Processor FPGA Altera EPF8282ALC84-4 -CCD Philipps FTF3020C -LCD www.sharpmeg.com LQ038Q5DR01 3.8" 450nits 320x240 (4:3) looking for a 3:2 ratio ---------------------------------------------------------------------------- BOM Component lists (From reference design) ---------------------------------------------------------------------------- - Philipps FTF3020C sharp LQ038Q5DR01 Electrolytic capacitor 100�F/16V Sanyo 16CV100GX Electrolytic capacitor 10�F/35V Sanyo 35CV10GX Electrolytic capacitor 47�F/35V Sanyo 35CV47GX Electrolytic capacitor 22�F/35V Sanyo 35CV22GX Electrolytic capacitor 220�F/6V3 Sanyo 6CV220GX Electrolytic capacitor 10�F/63V Philips 2222 036 78109 Electrolytic capacitor 68�F/63V Philips 2222 036 38689 Chip Capacitors Philips Chip Resistors Philips Micro chip inductor 12 �H PM10 TDK ACL3225S-120K-T Micro chip inductor 27 �H PM10 TDK ACL3225S-270K-T Micro chip inductor 56 �H PM10 TDK ACL3225S-560K-T Crystal 20MHz 49SMLB Saronix Common mode choke TDK ACM3225-102-2P-T Adjustable coil 820nH 5CCE Toko 638AN-0163Z=P03 Analog delay line 3ns/100E Showa AT-03 Analog delay line 5ns/100E Showa AT-03 Analog delay line 15ns/100E Showa AT-15 Hex Inverter National 74AC04SC Quadruple latch Philips 74HC373D Op-Amp CLC505 ComLinear CLC505AJE-TR13 Dual LF Op-Amp AD706 Analog Devices AD706JR Dual LF Op-Amp AD822 Analog Devices AD822AR Op-Amp AD8011 Analog Devices AD8011AR Op-Amp AD8041 Analog Devices AD8041AR Op-Amp AD8002 Analog Devices AD8002AR Op-Amp LM358D Philips LM358D Op-Amp TL082D Thomson TL082CDTS93 Precision voltage reference LM4040 National LM4040 CIM3X-2.5 P-channel MOSFET IR IRLML5103 N-channel MOSFET IR IRLML2803 A/D Converter Burr Brown ADS801U MOSFET Driver Micrel MIC4417BM4 CoolRunner PLD Philips PZ5032C FPGA Altera EPF8282ALC84-4 FPGA Configuration E�PROM Atmel AT17C65-10PI Reset Watchdog Circuit Maxim MAX823MEUK 5V1 Zener Diode Philips BZX84-C5V1 BAS28 Diode Philips BAS28 BAT74 Diode Philips BAT74 BFR92 Transistor Philips BFR92 BC850 Transistor Philips BC850 BC860 Transistor Philips BC860 BSS83 Transistor Philips BSS83 BSD22 Transistor Philips BSD22 BCV62 Transistor Philips BCV62 BST120 Transistor Philips BST120 - This message is from the Pentax-Discuss Mail List.
