  1. We do not support users making their own boards, nor does the license for the soruce code allow it.
  2. The two boards were IFOSD's, stacked one on top of another feeding from one into the other. YOu could do that with dragonosd's but not using the one bob4. We plan to eventually put a scripting language into the DragonOSD Pro version which we're working on, this would allow you to script waypoints and make things happen when you get there. If your dropping candy, please do so near my house If you want to work on code, getting a MikroElectronica dsPICprog is the best thing you can do for yourself. It connects to the IDE we use and allows you to watch the MCU running through code/pause it and such. Fantastic for debugging code! The old board schematics are not compatable with the V1/V1.1 boards, you wouldn't be able to use the IMU or expansion ports, or the newer source code on there.
  3. Once you get good, with the right tip you can get just the right amount of solder on the tip of your iron and use surface tension to go down one side, leaving just the last two pins with a blob on them. A bit of solder wick can quickly remove this. I use SMT tweasers to hold the IC in place as i tack the 4 corners, putting solder on first i find makes it very difficult to get it sitting flat and straight. H.J.Gelsthorpe, i've built a reflow oven out of a $35 toaster oven. It has top and bottom heating elements, and i put two pieces of aluminium sheet at the top below the elements, and two at the bottom above the elements which really help smooth out the heat. Simply preheat to desired temperature (a bit hotter than the solder paste needs), place in oven, keeping the temp fairly low - so the heating elements dont start to change colour - wait for the smoke from the flux to stop coming out and then turn off and let slowly cool. Works fantastic. Also, as far as tips go, i have some 0.2mm and 0.6mm chisel tips for my soldering iron, but i now find i do a better job with the 3mm chisel, it applies heat quicker and easier especially on ground parts, thermals or not. It also allows you to pull more solder off if you put too much on, it's all round far easier i've found. Sander, your board looks like it was stenciled, you can see mounds of solder on blank pads, and that the IC's have floated - not been hand soldered.
  4. I didnt receive any emails either.. mark-AT-intelligentflight.com daniel-AT-intelligentflight.com for dragon stuff
  5. I'm thinking if you want to use the dragon on a helicopter you're going to have to dive in and start modifying the code yourself to make it work. Do you know C?
  6. Once our new 12v step up power supplies arrive, i'll be bundling them with cameras very cheaply so that people can run their cameras off 5v We're working with the camera manufacturer to make the cameras 5v if possible. While i'd love to do some comparative tests, currently the weather is too crappy for me to fly, and it's very overcast and dark outside (unheard of for this time of year...) so i cant even just point it out the window with a 131 to compare them. Once we get some nice bright sunlight and winds under 20km/h i'll compare them. You can look at the videos in this thread, and the photos in the mean time.
  7. Mugur, When ordering, you chose Internation Parcel Post - AIR. This is uninsured and does not offer tracking of any sort just as started on the confirmation of your order being posted As it is christmas time, Australia Post are saying it may take up to 20 days for delivery rather than the standard 7-9 days.
  8. saabguyspg, yes thats me :eek: heh. That was with a really early beta version of my software which used the EMATracker object, not EMADevice. Phils program is far better suited to it
  9. Mugur, Nothing since the email i responded to on Wed 28/11/2007 10:16 AM
  10. The 4455 is an alternative.. but $100, and 8 channels. Been trying to get them to make a single channel of it, they're not having it through.
  11. pseddon, You sure you got the right wires going to the right pins? I know thomas uses a 5 or 6m gps cable unshielded no problems, he puts the GPS in his garden so he can track satellites when working on stuff. lol. Ever tried putting a tiny bit of wire between two SMT pads 0.2mm apart? And then reflowing it? With a machine?! 0ohm = safe and easy. As to PM's my inbox is perpetually full here. I think i remember seeing an email, but didnt see any questions in it so didnt respond. *shrug*
  12. We do have someone working very hard on the website for the dragon osd which is where all this info will end up Power source: battery seriously though, 2-3s should be fine (we have a bigger regulator for 5v now) Current sensor: We're getting a set of IF Current sensors specially made for the dragon OSD with a 0ohm resistor in place of the 10k. These will be completely plug and fly GPS: As always, our GPS have the correct connector installed as standard when ordering bundled Soldering: As far as i'm aware.. only the battery connector needs to be soldered to the board, and i'm going to add the option for a 2.54mm spaced header for this if people want it pre done for them. Personally, i'll be soldering a cable with deans to mine so that there is zero to no chance of the dragon coming unplugged in flight.
  13. We wont be distributing the Dragon via usual channels for some time yet. We want to get the dragon website fully operational and with all the project/code sharing features we've been dying to implement before we even think about distributing them. We feel that the community we want to build around the Dragons is going to be vital to it's long term open source success. So just order from IF, new stock due 3-4 weeks we are told by the manufacturing company. We've got a lot more than last time so hopefully they wont sell out so quick, and we plan to make more as soon as stock levels begin to run down.
  14. Mr Pibb, I thought i had responded to you sorry! These are not made by KT&C We should be having stock of them in approx 7 days.
  15. Multiuse inputs/outputs for people to use in their own software! Power to the OSD is from the onboard 5v regulator (the larger one), the 5v regulator then supplies the 3v regulator.
  16. Oh yes, and Mr RC Cam, please don't get upset at me about posting a product offering in here at $20 with postage, paypal fees, packaging i actually loose $0.06 if i calculate it right, so i'm not offering it for profit!
  17. I can send you a very small TTL to RS232 board for $20 (includes postage). Its pretty much just a MAX232 with the caps around it, it's what we use in our serial converter cables. 19mm x 13.5mm. I'd get a photo but i kinda killed my camera, and am waiting for the new ones to arrive $20 is so very close cost price
  18. Havent arrived yet, so no Here is the PCB though if you're interested. If you don't like the new layout, its my fault These are 4 layer boards btw
  19. I used a Castle ESC as a 5v power supply for a 400mw lawmate, camera, osd, gps yesterday for many hours. I used it out of convenience because i couldnt be assed getting the 3A IF psu out of the other plane lol.
  20. People tend to lose orientation with where they are flying from, and can't work out how to get back, rather than seeing the horizon. Horizon is super easy to find, If you see sky, nose down, if you see ground, pull up OSD's are there to help you find your way home safely.
