  1. Ok, thanks. Yeah I prefer to buy rather than build! I post any results I have from a search...
  2. I only just found out that the inspire is your creation! First.. Congrats! A great device.. Ah.. i must admit that I usually don't forum much, since my business is all about software I don't spend much time on the computer after work ! Does a mechanic go home and play with his car?? Answer: Not after being one for 20 years! After reading the other project forum, my guess is that I need is a device that sits between the GPS module and the OSD. Requirements: 1. A push to record the single waypoint (home position) switch from the current position. 2. The device passes through the $GPGGA and
  3. Yeah I saw that project and suddenly it stopped. So if the inspire does not have a waypoint engine, what input data does it use to display the distance/heading data on the screen.? (In other words what do I need to feed it to make this waypoint display feature work?).
  4. Not sure if this info is elsewhere... I am using the Inspire OSD. I am really pleased with this unit! The features are great and after yesterdays field testing of the RSSI functioning, I am totally stoked.. Now.. I am using the 5Hz micro GPS, and after going up to 1000 ft yesterday, (a requirement of our AP work) I found that it was a little hard to find the home field! All those roof tops look exactly the same! I got back ok, but immediately realised the value of a bearing and distance to home indicator. Luckily the inspire has a waypoint bearing/distance indicator! Only problem is I dont
  5. Well Well, I have been smiled upon! The pin is correct, it is the RSSI pin for both the Futaba 72 MHz G3 receivers 5014DPS and 5114 DPS. The voltages vary slightly between models but low (no signal) is .667 V and .775 respectively, and high (full strength signal) is 1.987v and 2.21v. I soldered wires to the ground and RSSI pinout, plugged them into the RSSI input on the OSD and Bingo! it works like a charm. A walking test recording to my MP4 player from the video RX shows the signal strength indicator working like a charm.! When RC TX is turned off the OSD RSSI indicator flashes to note no s
  6. I purchased the 1000mW 2.4 (with Yellow jacket Pro) and the 500 mW 900 MHz from future hobbies. Wade had been very helpful and the shipping was fast. I am located in SE ASIA. I have tested both. Using the standard antennas the 2.4 is no where near the quality of the 900 Mhz for range and clarity. That all changed when I added 2 high gain patch antennas to the Diversity RX on the 2.4 Mhz. Wow, very clear and range is great. We only test fly at 500 ft and below, and within a 1 KM radius of the antenna but I was impressed. I played with the patch orientation and it matters immensely. Low to the
  7. Mr RC-Cam... Well after some prodding about with the DMM I have these results.. The pin in the picture puts out 1.987 volts when the TX is turned on next to the receiver. When the TX is turned off it drops to .667 volts. Then when I moved the TX into another room in my apartment with 1 brick wall in the way, the voltage dropped to 1.877 volts. When I moved the TX into the bathroom (3 brick walls away) it dropped to 1.574 Volts. I put in inside the bath (without water!) and the voltage dropped again to 1.398 volts. Bringing the TX back into the room next to the RX and the voltage read 1.987
  8. Absolutely, positively dont know! I am an old RF engineer from the days of discreet components where the high powered stuff still used valves! I have not played with radio gear for 28 years! My eyes are also not what they used to be. so I would trust your gut feeling over my observation anyday... Anyway.. upon further squinting I can see a little chip on the "RF Board" sandwiched between the 2 boards. Maybe this is the thing I am looking for? Ye gods, unless I break out the micro desolderer, a large magnifying glass and the ACME hand steadier MKVI, there is no way I will be checking its pino
  9. Thanks Mr RC-Cam. I have opened it up, the problem is the chip (I am pretty sure its the right one) has Futaba code and no other manufacturer IDs. Kinda makes it hard to check out the pint outs. Number is FP6350B. The only other number s 612201J. Anyone have any ideas about the possible pin outs? I thought of probing around with a DMM and seeing if I could see a voltage thats changes when the tx is turned off and on... I figure that if there is a rssi then it should drop to low value when there is no tx signal present. I am not sure how these work but there must be someway for the receiver t
  10. I have searched through most of the forums and I hope this is not somewhere else, if so please direct me to the correct topic. I have a Futaba 14MZ with R5114 receiver (72Mhz). I am using the inspire OSD on my Trex600 and so far the whole project is going along nicely! I want to use the RSSI on the OSD, but I cannot find anywhere that can help me find out the following: 1. Does the Futaba R5114 receiver have an RSSi pin? 2. If Yes, Where is it on the circuit board? 3. If anyone has any data about connecting the R5114 to the RSSI input on the Inspire OSD ? Maybe buffer circuits needed etc.
