The guy, who answer you have superficial knowledge of automatic control system. The automatic control system do not pulses or value of voltage only - this is complex mathematical modelling of process. Afer you will have mathematical model, you can building of system of automatic control on any components. This can be analog computational algorithm ( operational amplifier) or digital automaton or microporcessor. The speed control - this is complex problem and this is problem can be describe like PID control. If you study of initial systems of speed conrtol, yes, this systems had block of frequency comparison and analog conversion of control of DC motor. That's why, the 555 timer with low precision of parameters of output signal, pase locked ship - technology of last century. Yes, this will work, but with low value of parameters of speed control. About stepper motor and motion control. This is verygood idea, but, you must draw attention on magnetic characteristics of stepper motor, the time of dead time, inertia and other. If you wish build of cheap system, 555 chip will good choose, but, do not wait of high technical parameters of speed control of this system. All modern compoters included of generator of main frequency and this is crystal sync generator ( or built-in generator of processor ). Any case, this generator can run on quartz resonator, or on RC components.

Spring motor module. You have Konvas-1 camera , KSR-1, or KSR-1M. But, i will ask you, what kind of manufacturer ? KMZ or Miskonap ? You have magazine lock from left or from top ?

If we told about spring motor, you mean of Konvas-1 camera ( KSR-1, KSR-1M ). Konvas-1M cameras, 1KSR-1M, do not had of spring motor. The next, Konvas-1 can be a two main versions, made in Krasnogrosk fatory and made in Moskinap. Konvas-1, Krasnogorsk factory do not compatible with Konvas-1M, 2M cameras. I had cases about replace of Konvas-2M front panel with OST-19 lens mount on body of Konvas-1M camera. But, the procedure of replacing included a many additional procedures of grinding of front panel with rear side of body. The special procedure of centering of front and rear parst of body, because, the lens mount set at front side, but, film gate set at rear side. That's why, the front and rear side connect by to big pins. If this questions bery important for you, lety me know of version of Konvas-1 camera and i can take of similar body and front panel of Konvas-2M and anver on your question detailed. the second question - flange focal distance of lens mount. The next body will ask of dertailed adjusting of flange focal distance. And, Konvas-1 have direct viewfinder, Konvas 1M, 2M have rotate viewfinder.

The camera can be to buy or rent from Moskov, Kinor company. http://www.ctt.ru/rent/dc_rent/ For note: rental price at Moskov: SET 2 HIGH SPEED Large: 1х camera KINOR DCHS http://www.kinor.ru/products/camera/dchs/ 1x HD recorder DCR160 (40 minutes) 1x set PRIME LENS ELITE (5 pcs) 1x HD disk recorder HDR30 (6 hours) 1x HD24" Monitor Playback FULL HD 25000 RUB/ day ( near $800 ) Sorry, I do not know, who have of Kinor digital camera in the UK and USA. You can compare of price of rent of Phantom HD and price of Kinor digital and choose of better.

Yes, The mechanical speed regulator set inside of KSR-1, KSR-1M camera body, under of indicator of speedmeter. If you will see detailed, you can see small lever with scale 0...9 under of indicator of speedmeter. This is lever of control of mechanical speed regulator. Konvas-1 cameras, KSR-1, KSR-1M can have : - DC electrical motor with rheostat speed control, - spring motor, - hand crank for single shooting - hand crank for " normal " speed shooting. At time of design of Konvas-1 cameras, we do not had of effective electronic speed regulators, that's why, the Konvas desigher use of idea of mechanical speed control. This is special device, set inside of body of speed metter of Konvas camera and set on body of camera. The mechanical speed regulator take of rottation from main axis of mechnaism, included two counterbalances with spring. The design of mechanical speed regulator of Konvas camera similar of design of any mechnaical speed regulators of cine cameras with spring motor. If you run of camera, the rotation from main axis of mechanism to pass on rotation of counterbalances. And the centrifugal force will press of counterbalances to break by systems of levers. The spring will counteract of centrifugal force. At final. If the speed of axis of mechanism of camera will have more high value from, the counterbalances will press on break and will extend of resistance of rotation of all mechanism. If the speed of axis of mechanism of camera will diminish, the speed regulator will deminish of resistance of rotation of all mechanism. The mechanical regulator use for speed contol with electrical motor ( rtheostat control ), with spring motor and with harnd crank run at " normal " speed. The body of speed regulator included of speed regulator with lever for speed correction and speedometer with indicator. The procedure of speed setting of Konvas-1 camera with electrical motor. - to set of lever of speed regulator on position minimum resistance of rotation . - to run of camera and set rheostat of motor on position of 26..28 fps speed. - to change of position of lever of speed regulator and adjust of speed of camera on value 24 fps. You can see, the mechanical speed regulator inportant device for speed control of cine camera with electrical motor with rheostat control, with spring motor and with hand crant shooting.

If we told about original electronic of 17EP-16 APk motor, and 14..18 v battery, the problen can be with 9v voltage regulator of main electronics and transistors of pre-amplifier of DC motor. To need to check of version of module of Taxo board MKBI.687253.xxx. ( small second board from power plug). The matter is that, this is module included of voltage regulator of 9v of main electronics and can have version with low power transistor of high power transistor. The low power transistor ( prevailing version ), can be KT503B with maximum voltage limit 40v and can be "KT503G" with maximum voltage limit 60 v. But, KT503 transistor have maximum current 150 mA only. That's why, the 14..18v battery can burn down of KT503B transistor of voltage regulator The more modern versions and upgraded versions of taxo boards can have more high power transistors KT815B or KR142EN8A ( 7809) 9v 1.5A. The second "weak spot" - transistors of pre-amplifier of DC motor. This is KT502, KT503 transistors and can be " B" versions with voltage limity 40V. If we told about moderm microprocessor controllers of 17EP-16 APK motors 1414, 1416, 1420 version, the 16...24v battery do not problem. The matter is that, the speeds more 32 fps will ask of battery with mor ehigh voltage. 50 fps speed ask of 18 v battery. The modern, microporcessor controllers have big power reserve. The controller included all electronic components with high voltage reserve. The protective diodes at input stage of controller have voltage limit 100 v, the capacitors of input stage -limit 35 v. Output power FET transistor have limit 75 v. The voltage regulator of microprocessor power source have limit 35 v and maximum current 2A. That's why, I think, you can connect of 24 v battery without trouble.

As for me, the mechanism of shift/tilt for any lens - high precision mechanism and will ask of many precision turning/milling procedures. I discuss with guys from Hartblei about product of special edition of shift/Tilt lenses with Arri Pl lens mount and Zeiss glass, and this project will finish at future. If we will told about finished devices, you can have versions : 1. to use Hartblei shift/tilt lens, like Super- Rotator + Nikon C-mount adapter. http://cgi.ebay.com/Camera-Nikon-MC-Hartbl...id=p3286.c0.m14 2. to use of Tilt adapter "Pentacon Six lens" to Nikon mount + Nikon-C-mount adapter. http://cgi.ebay.com/Hartblei-Tilt-Adapter-...id=p3286.c0.m14 You can attach of Pentacon Six 30 mm, 45 mm, 65 mm, 80 mm, 120 mm, 150 mm lenses. This can be Russian Kiev-60 lenses or Carl Zeiss Pentacon Six lenses. Yes, the final price can be a some high.

Kinor DCX camera, 4K, 8K, 16 K, speed up to 50000 fps HD resolution, up to 10000 fps, VGA resolution up to 50000 fps. http://www.kinor.ru/en/products/camera/dcx/ Hi Speed Kinor DCHS 2K, speed up to 2000 fps on full HD, 20 minutes of record time. http://www.kinor.ru/en/products/camera/dchs/

If you wish to check of start-stop trigger, you need open of front panel of camera. The main front part of body cover of thin plate with LOGO and glue to main front body. You need take away of thin plate and after, you can unscrew of 4 screws and open of front panel of body. The trigger included flat plate with pins and gear with pins. The pins on flat plate jam of pins on gear and mechanism set at shop. After you press on start stop button, the flat plate move and pins set free and mechanism to run.

Konvas-1 cameras ( KSR-1, KSR-1M ) had spring motor. This is rare device. Spring motor of Konvas-1 do not compatible with Konvas-1M,Konvas-2M cameras because, this is cameras have different design of mechanism. Konvas-1 camera have devices for mechanical speed control, and mechanical start-stop trigger for use of spring motor. The cine camera with spring motor must have mechanical, inertial, speed regulator and Konvas-1 have this device. If you interested of 35 mm spring motor camera, I can recommed to learn of russian AKS-1. This is camera have build in spring motor.

You can use finished devices- Hartblei shift/tilt lenses. http://www.luminous-landscape.com/reviews/...artblei45.shtml http://www.luminous-landscape.com/forum/lo...php/t13228.html http://www.hartblei.eu/index.htm Hartblei lenses can have versions for Canon, Nikon and other 35 mm SLR photo cameras. You will need attach of lens mount adapter only.

Good project. I hope you have experience at create of electronic controllers with PID control. If the any body need upgrade of electrpnics of CP-16 camera or other cameras now, We can propose of a few versions of real microprocessor controllers of crystal sync speeds from versions with fixed crystal sync speeds up to versions with speed synthesizer 5-50 fps step 0.001 fps, time lapse, film counter and remote control functions. The many filmmakers use of Konvas and Kinor cameras with our controllers. I will be glad to compare of your controllers.

I have crystal sync speed controller with Time lapse mode of cine camera motor. This is controller build for upgrade of motors of russian Konvas, Kinor cameras but, can be use for upgrade of other cine cameras with DC motor and optical or magnetic feed back. The controller have 21 crystal sync speeds LCD dispay, digital film counter and Time lapse mode with time of waiting of next shoot : 1, 2, 4, 8, 15, 30, 60, 120, 240,600, 900, sec. The more detailed information by PM.

I worry, this is do not problem with start-stop trigger and do not need take away of front panel of body. At first, need check of main cog's wheel and rollers near cog's wheel. The matter is that, the cogs of cog's wheel can jamed on body of rollers. May be, the position of cog's wheel adjust do not correct and cogs do not go at cuts of rollers.

My customer to have for sell Konvas-2M, OST-19 lens mount, with upgraded 17EP-16 APK crystal sync speed motor, without lenses.

At first, we must know, what kinds of type of optical scheme have anamorphic lens. This can be lens with front anamorphic adapter and lens with rear anamoprphic adapter. If we have anamoprhic lens with rear anamoprhic adapter, this is lens can use at spherical and at anamorphic version of assembling and front diopters adapter can use at anamorphic and at spherical version of assembling of lens. The russian zoom lens 35 OPF-7-1 25-250 at spherical version and 50-500 mm anamorphic version with fear anamorphic adapter had set of diopters for shooting with short distance 0.75m, 1m. And this is diopters use at spherical and at anamorphic versions of lens. If we told about anamorphic lens with front anamorphic adapter, we need use of front dipter attachmnet with big size round form or big size with square form. The wide angle anamoprhic lenses do not had diopters attachment, because, will need have big wide angle of view. The russian prime anamorphic lens 35 BAS 4-10 ( 50 mm ) and similar had square front diopter attachmnet for shoot with short distance 0.8 m and 1 m. The very god result have complex optical schemes of front diopter attachmnet with a few glass inside. As of our experience, for macro shoots, we use of round glass LOMO anamorphic lenses 35 BAS2-2 150 mm with hand made front attachment. We had size of subject of shooting 3x5 sm.

Ukrainian TV journalists of "51 TV channel " stopped of hunger strike at 24.07 after received of phone call from assistant of President of Ukraine with invitation to discuss of situation with "51 TV channel" at monday. The leader of strikers Viktoria Shioiva was hospitalize at Friday to regional hospital at faint. I hope, the strike to showed of real faces of our local officials for all peoples . We will have elections of President of Ukraine and peoples can do of correct choose. Thank you very much of all guys. I think, we can close of this topic.

The fluorescent lights of train can have electronic ballasts with 20k-30k frequency. 60Hz AC have full syncronization with 24 (30, 40, 60, ) fps. The difference between 24 and 25 fps important at sync sound recording only and 24 fps footage can be transfer on 25 fps at post production. For note, Konvas-1M, 2M have 150 degree shutter. As for me, I draw attention on color balance more, because, fluorescent lights can give green color. The russian trains have "emergency lighting" with incandescent lamp. I do not know, you can upgrade of train or not. We had similar sutuations of shooting inside train and setup of additional lighters and had good result.

Hi Serge Thank you very much for countenance of our Journalists Yes, we live at beauty country, but, a some politics think, what they god and can do any, what they wish. And i hope, our Journalists do not lost of honesty. If we lost of freedom of speech, we lost of freedom at our life.

News, today. The translation of official order of General director of State committee of TV and radio of Ukraine. "On today, in Dnepropetrovsk regional state TV-radio company through conflict of the general director to company Shilovoy V.V with local organ of power and broad circle to public formed the situation, which does not allow effectively to work TV-radio company, creating at condition for biassed of the elucidation event in region. For the reason adjusting the relations between Dnepropetrovsk state TV-radio company and regional state administration, considering term company non-execution of the state contract on production and spreading TV-radio shows and programms accepted decision of the termination of employment general director Shilovoy V.V with occupied to job titles." Original order : http://comin.kmu.gov.ua/control/uk/publish...mp;cat_id=64654 http://gorod.dp.ua/news/news.php?id=18668

The 5' days, journalists to hunger. On this day, the government official to issue an order to retire of leader of journalists of "51 channel " to directors of "51 channel " Viktoriya Shilova. The deputy director of "51 channel" deferred at law-enforcement state office the day before yesterday. This is result of pressure on State machinery from governor Dnepropetrovsk Viktora Bondar. The first political leaders of Ukraine do not visit of striker,however, to had work visit to Dnepropetrovsk yesterday. This is real fase of freedom of speech at Ukraine.

Konvas and Mitchell, two difference class of 35 mm cine cameras. Konvas - small size, low weight, hand-held 35 mm cine camera. To have 400 ft and 200 ft film magazines, low weight crystal sync speed motor. From otehr side, Konvas mechanism have one pin of claw mechnaism and have high value of noise. Mitchell 35 mm ( NC, GS ) studio cameras, have big size and weight and 400 ft amd 1000 ft film magaiznes. And, the mechanism of camera have transport and registration pins. That's why, this is camera a more high class. But, you must find of special battery, crystal sync speed, high power motor. Konvas can have OST-19 ( Konvas-2M ) or OST-18 ( turret Konvas-1M ) lens mounts. Konvas have of anamoprhic film gate, de-anamoprhic viewfinder, set of anamoprhic prime and zoom lenses. And all this equipmnets will ask of less value of money. Konvas spare parts, service available.

for note, russian stereoscopic http://www.stereokino.ru/ennews.htm

Yes, our regional governon wish see on TV only good news and praise of executive power and suppress of any news about real situation of our life. On last week, our sanitation company, regional monopolist, to level up prices at 150%. And, only "51 channel " to show of press conference about discontent of citizens. I do not told about unemployment and advance in the cost of living. The our regional governor propose of personal money on foods for hungry journalists, and do not more. Yes, the many ukrainian, russian funds and a some politicians to countenance of strike of journalists and i hope, we uphold of freedom of speech. I do not work on TV, but, i have many friends and colleagues on TV. And i can't to go by.

The additional information. The Journalists Dnepropetrovsk, Ukraine, State TV channel “51” have declared the permanent hunger strike in token protest against unprecendented pressure on телеканал on the part of governor . About this is spoken in message 51 channels , which text disposes the information agency NEW BRIDGE . Journalists 51 channels have declared the permanent hunger strike in token protest against unprecendented pressure on TV channel on the part of governor Dnepropetrovsk Viktora Bondar. Beside TV channel are arrested count, silent telephones, impossible buy gas for outside TV news, repair and contain television equipment. On length last 8 of the months on TV channel passed 10 checks checking State institutions. The Journalists require meeting with President of the Ukraine Viktorom Yuschenko to defend the TV channel and protect the freedom of speech, human right and right of the choice , - is spoken in message. As earlier reported of information agency NEW BRIDGE . , April 30 2009 Central administrative board of Ministry of Internal Affairs at Dnepropetrovsk area has agitated the criminal deal on fact by occupation by fraud by property in specifically large size Dnepropetrovsk TV state channel, which leads Victoria Shilova. the March 12 governor Dnepropetrovsk area Viktor Bondar addresses to managament of Central administrative board of Ministry of Internal Affairs at Dnepropetrovsk area , checking-revisory management and State committee of TV and radio with request about undertaking the check comparatively no-purpose of the use by director Dnepropetrovsk TV 51 channel of 5 million Grivna., chosen by regional budget in 2008.
