  1. Some off topic - but here are the wishes for all of you http://niespodzianka.info/goj Merry Christmas
  2. I had some questions about - i will consider T1 input (new board design) for this purpose coneccted to any free RC channel , however all depends from freee space in chip . For now this 16K small chip holding suprisly lot of informations , countings and functions but one timer is still free .
  3. This parts are inductances - all can be 4,7 to 10uH - goot to add some inductances at both ENG input - also for all ADC inputs - this will help to cut noises from/to RC circuit . If you need naked PCB , write me at PM or at remzibi1-AT-poczta.onet.pl
  4. Here are all compacted informations and files - still growing . http://rc-cam.info/viewtopic.php?p=17008#17008
  5. It is open hardware project under TAPR licence , so not copy and sale allowed - but for personal use no problem . Naked printed bards avaliable or ready devices as complete with(or without) GPS modules . Software is not open source but all compiled files are avaliable , as firmware , font and config files and PC software (in fact all included in PC software).
  6. Fortunate community of this OSD owners are growing and growing , including FPV flyers but not only , even some universitys and high schools for experimental use and other projects adaptations as well as some home designers . So lastly I have many additional questions similat to like that : I like to use OSD in another use - on combant plane (with graphics and sigt to aim enemy) , on boat , on U-boat , on RC-car , on real car with recording , on bicykle , on motorbike as parameter monitor , on my Video monitoring system cooperate with PC , on my personal Videos information stamp , on Video as frames counter (whatever it means), on my own top secret project , so can not tell you about , etc. etc. and many more . I do not need to use GPS - I do not need it , I like the analog inputs use only - like Voltages , external sensors and possibly RPM meter . OSD is cheapper without GPS . So that is OK - here is the firmware for beta testing for everyones want it to test - working without GPS module at all . All other advantages are remain without change . Button work only as Video mode changer and save (something like save home) function saving Video mode and reseting timer at any moment . Iviting logo will gone after 5 seconds so not any save needed for proper work . So after firmware update all information regarding GPS data are not displayed . Other like Timer , GMT date (will be zero so made it invisible) , GMT time (will be zero so made it invisible) , Frequency meter(RPM meter) , ADC , and graphical object are displayed without changes - all can be configurable (scaling , alarms etc.) in usual way using PC configuration program . Character editor and all rest - works in usual way . Free UART(COM) port is set to default 38400 baud rate receiving and can be used to display on OSD layout absolutely everything we want or need to display at any location using external device - if we want to connect any . Now for those programerrs who want to display anything using that port and their device . So we can deliver information to display at location x,y looks like that : [leading character][text message][ending character][ending space] ending space is displayed always after mesasage. String to OSD shoult look like that : "$MXXYYLLEEabcd" must be end by enter character CR LF linefeed and carriage return . $M - means that it is meassage to display (M must be uppercase) XX - is a x coordinate on screen , must be hex value YY - is a y coordinate on screen LL - is leading character hex value from font table EE - is ending character hex value from font table abcd - is a "text message" to dispalay when LL or EE is Hx00 - then will be not displayed at all when text message is "" [empty] then also will be not displayed So string to OSD can belike that in C aduino sample serial.println("$M050a4a4bI like that") so at location x=05 y=10 will be displaed this : <I like that> as you see LL is 4a it means [<] char and EE is 4b it means [>] char . or can be done like this way: serial.print("$M") //header for message serial.print("050a") //x and y coordinates serial.print("4a4b") // leading and ending characters(graphics) serial.println("I like that") //message with LR CR ends string This is exactly how is working this function in OSD now . As advantage of this system when we define most significant bit of XX coordinate for 1 then we choose small fonts for text message display (only capital letters) - when is 0 then default big letters are displayed from characters table capital and small letters . XX |= (1<<7) // set 7 bit for small characters XX &= ~(1<<7) //reset 7 bit for big characters To be possible custom screen configuration , need of understanding how it is work . The screen is divided on net where the charcters are writen .The grid is 30x16 with PAL mode nad 30x12 in NTSC mode . Looks like that: . X------> Y 1 2 3 4 5 6 7 8 ... 29 30 : 2 : 3 : 4 v 5 . . . 15 . 16 So when we made configuration we just teel the program where on the screen we want first character(or graphic) of our information - up left corner is coordinates X,Y (1,1) , bottom right corner is X ,Y (30,16) - remembre that NTSC mode Y must be no more than 12 . How do we know what mode are currently in use ? - we will see after OSD init logo . I hope that this firmware will help for many peaples doing his own project and will made poor man's OSD more open to world , also be more universal to variouse usage in many other project , not only flying platform . ------- I foloowed of mmormota idea about add to OSD firmware ability to display any custom information delivered by RX input at the same baud rate with GPS module . So if anyone have external device with GPS and retransmitiing GPRMC GPGGA messages , OSD can be used in usuall way - inluding autodetecting baud rate . But also in middle of NMEA messages is possible to put custoom dispaly instruction - all described detaily in post above . So here is the beta version of firmaware 1_60 - mostly for mmormota to test with ardupilot software . It is working exactly as remzibi OSD (including GPS configuration commands sent at begining by TX line after baud rate detection) plus ability to display any custom oinformation delivered by UART(com port) in the middel of NMEA messages , format described in post above : "$MXXYYLLEEabc" So with this solution there are a bit solved problem of insufficient space in OSD's chip . maybe will be possible also displaynig artifical horizon and pitch using characters E0 to E7 from character-font table . Here are some pictures of possible GPS connection with external device and OSD .
  7. The chip is extremly well described in datasheet - in my unit first letters I was able to display literaly within 3 hours . Within two evenings all functions for display anything useful was ready . I recommend to read datasheet - there are also explanations for some tips .
  8. New software is realsed : button function - save home position (short click) - video mode change (NTSC or PAL) press and hold button for about 1 second - cofiguration mode (pressed when conecting to power) show information DONE : - latitude - longitude - speed - altitude - to-home course - to-home distance - satelite quantity - video battery voltage - main battery voltage - flight timer - variometer - UTC Time - UTC Date - alarms for distance , ADC , atitude , batterys voltages - 32 static displayed independent graphical-character symbols configurable - 6 additional sensors on ADC channels , each individually calibrated and alarm set - after detection 0 speed for cinfigurable X seconds , shows maximal values for altitude , distance , speed OSD board after face-lifting looks like that : http://img19.imageshack.us/img19/7995/s6300953.jpg http://img32.imageshack.us/img32/4643/s6300970.jpg Small video tutorials Firmware update if newer version avaliable http://vimeo.com/4698791 Update of BIN file (as well as Font file) http://vimeo.com/4698755 Example of using ADC channel for external sensor - here RSSI information http://vimeo.com/4698633 and for play and funny F-16 HUD screen layout captured All avaliable for downloads - so every one can update his unit http://rc-cam.info/viewtopic.php?p=1734#1734
  9. Better NOT . At first units was 5V provided but this done more problems than advantages - simply connect USB cable and connect to external battery OSD for supply , as the supply input(12V) is protected against opposite connection . 5V is not protected by any way , so any accident will cause of burned OSD unit - and this is what we do not want to experience . So always use external battery for power-up OSD - USB cable use only for communication , not for supply .
  10. 2.4GHz TX was covered by trees and lose range . 1.2GHz video downlik was working perfect till last moment .
  11. You right - RC RX is very sensitive for any external glitches and his range can decrease dramtically with bad connections or mess in cables .
  12. There is almost ready software with additional ADCchannels - also for current sensor (any current sensor - possible calibration , even two way curerent sensors) - it will work independently from engine (main battery) voltage measurment . Read some more here http://rc-cam.info/viewtopic.php?t=178 - there will be update with files when ready . The main goal of that OSD was not occupy any RC channel - so it be possible to use with anyone even with very cheap 4 channel TX or 3ch (car) . I do not plane to made any turn on -off function - but never say never . instead of turn-on-off dispal - it is ability to arrange custom icons and information on screen most sweetable for any user needs . By the way here is the II FPV meeting 2009 in Poland - here are briefly showed some of our harware "inventions" , and crash with clear picture untill ground hit . http://vimeo.com/4675558 New LINK
  13. I didn't expected but for some users reference I must also add the GPS picture with expalnation what side is UP what is BOTTOM . Label is always bottom side , GPS must look the UP side to the sky looking for SATs . I know that even in opposite side it can track 8 sats but better is to keep antenna looking in to the sky
  14. You do not need clibing (faling) rate ? you can use it as graphic indicator like arrow up or down or graphic plus numeric value of climbing or falling rate . This climbing rate is working very accurate as the altidude drift is very slow and climbing rate is derivative - so accuracy almost like with air prassure sensor . Anyway - it is absolutely your invetion how you like have screen layout done .
  15. Terry - you removed almost all information from screen . Let say - it is super minimal version of OSD .
  16. How it possible to mist first movie on UK ? that really pity . Next opportunity do not forget about your recoder's battery .
  17. This is not my set and not my movies , it is friend from forum . Here is the ground test of FPV with this camera - 4,5km no problem at 1,2GHz from RV . http://vimeo.com/3135227--WARNING-POSSIBLE-VIRUS This camera is HD Camocorder Aiptek AHD300 - it is 5MP CMOS-Sensor . I think that soon the better cameras will avaliable , so abilitis of aerial record also will increase .
  18. I must show this video - it is example of exelent results using HD Aiptek camera as record camera and FPV camera at one time , have AV otput . This type not giving any delays during record time so FPV is real time , and is possible to turn-off most cameras OSD . Pilot see OSD navigation information but recorded picture is not affected by it , also any possible radio glithes are avoided . http://www.vimeo.com/3334797 set: EASY STAR + RAY RANGE VIDEO 1,2 ghz AIPTEK HD OSD Remzibi DX7 Here is the over 1km high yesterday flight over mountains recorded as HD (look at OSD indication in PIP - 1040m) , pilot view is just very good with this camera . I think that for now there is not better solution for any cheap aerial recording with so amaizing HD results .
  19. Exactly - shield is not for prevent signal lost , it is even no problem if any lost will . Shield is shelding against external glitches and helping to not watch on screen how ESC works and other "electronic" events in the air .
  20. If cables are longer than 15-20cm use shielded ones - for shorter can be twisted normal , exept if you see any picture problems but then very probably is not only cables problem .
  21. Not yet , however shops ask about . I am looking for any manufacturer , as till now , for everyone who wanted it , all units for individualas i made by my hands . So till now is immpossible to talk with shop about prices for more quantity . It is Ok for not much pieces but if more peoples will ask for it , any factory will need for manufacturing . Already have new improoved version of board in Gerber files . About PC software now is almost ready - all updates of firmare , max7456 character table and configuration settings we can made by one PC software - no more hyperterminals or other separate programs . Added heading info - if anyone need is avaliable now .
  22. Some changes and some more features , added GPS datum support for world regions . Added 16 two character fully configured graphics objects - so for anyone with graphic talent any displaying style are possible to do - "star wars" style or "funny flying circus" - I do not know - I have not graphic talent at all . But HUD similar to F16 - why not ? - no problem just 5 minutes of settings in HappyKillmore's software . That curious how many things can be fitted in that mega16 chip .
  23. An exelent software for OSD configuration and setting , done by HappyKillmore is avaliable to download here : http://www.rcgroups.com/forums/showpost.ph...p;postcount=104
  24. I like to show an unusual flight of pilot nickname darkrall - with adventure . Here is the real fight to get back to base , he flow quite hight and get into low clouds , as in clouds camera lens was vaporated and only white picture , he had to back to airfield only by OSD indications , but there is not artifical horizon . The situation was bad because he had to flight against the wind (with wind speed 50k/h - against wind 10k/h) . Finally even without artifical horizon he made it - and got on field in one piece . His skills is proven as calsical modeler but he is very fresh FPV pilot , but he didn't panick and did it well . - http://www.vimeo.com/2879358
  25. Charles Beener relased his program for OSD layout configuration . Link for download here : http://www.rcgroups.com/forums/showpost.ph...mp;postcount=96 Any question about usage please ask him in link above .
