A very optimistic current sensor

It won't. Anything bigger than 6kb will not compile on the demo MikroC for dsPIC. I think Mark is working with ME on a web based compiler, not sure though.

Wow, some nice progress going on here. You have been quite busy these days Daniel. Well done!

Is not the crystal on the middle ARF soldered? It looks a little loose. Looking forward to the test results and new flight videos.

nice progress Daniel. when you are bored of the smelling that solder, can you post some WIP photos please?

those tiny regulators are lovely. And they would have looked even smaller on 0.6-0.8mm thick PCBs.

Wow, mE is doing quite well. How about an option to skip OSD routines based on a constant defined when compiling the code You know my purpose. Stream data and video to the ground, and do all the nasty things like OSD, and data analysis remotely.

Those boards look awesome. Some headers might need re-aligning a little bit (the factory was quite eager to get those shipped). Luckily, for me there will be a lot less headers as i will not be going for OSD, did I mention that? However still waiting to test that with bob4 (to have "been there, seen that") I am still looking forward to your updated schematics so i can post the simplified version of the board. You can call it DragonLite or whatever, since there will be no OSD I am still looking for radio link options cheaper than the maxstream modules so i can use them to transmit the instrument data to the ground.

Can you post more photos of the board please? Is it a multi layer PCB or just bouble-sided?

looks great. Did you solder the pin headers separately?

Daniel was sick a little plus the birthday thing...hope there was not too much drinking as this thread is silent for two day. I hope you have fully recovered now, Daniel.

docphi, are those traces around the current sensor you are talking about? or are you using any other high power stuff somewhere on your board?

Happy birthday then! May your lipos stay charged.

Sorry to hear that Daniel, Get well asap. cheers, m

Hi Daniel, I am not planning to control the plane, at least not in real-time, but rather in command mode, thanks to your DragonOSD, which i was hoping to use more as a pilot option. I can drop the bob-4 and use the I/O's for the downlink and some sensors. The duplex comm is in a future perspective, so for the beginning I will may start with simple broadcasting. That's 4.8Mbps roughly, is it that good or was it a typo? Not knowing the packet headers i can't tell how much practical data i can get at 4800bps (600bytes/second) will that be suffice for 5hz data update for speed, heading, alt... and 1hz update for batt voltage and current, temperature?
