Turnigy TX finally here

Turnigy TX finally here

Two boxes arrived today. Both much anticipated from hobbyking.com. The box hold the Turnigy 9x that I’ve bben waiting for. This TX sells so well that it is perpetually on back-order, and the do not allow placing pre-orders on it. Basically you subscribe to their email notification and when you get it, you rush to their site and place your order for it. Normally it sells out within half an hour of the email notification so you have to act fast. Lucky me for finally snatching one. I can’t wait to get all the mods done (I’ll document those on the blog too).

Together with this order, I picked up the Frsky DJT module with telemetry, an extra D8R-SP receiver cause I wanted the PPM signal, Zippy Compact 2200 Lipos, the 9x backlight kit in white, and a few other odds and ends. Now I can actually start taking some stuff apart and modifying it, cause to me that is part of the fun of this hobby.

In the next box I received the sensors that I ordered, cause it wouldn’t make much sense to have telemetry if I don’t at least send some data across. For now I settled on the voltage sensors, cause that’s the most important thing to keep track of when flying. I picked up both the individual cell sensor and the analog pack sensor so that I could get both the total pack reading and the individual cell reading (You will need both sensor if you want both types of readings). I also ordered the sensor hub to tie them both together to the D8R-SP.

Hobbyking was nice enough to throw in a set of Turnigy stickers as you can see. That will work as some cool graffiti for my tool cases. Stay tuned for posts about the mods and how they work out.

Power distribution and BT

Power distribution and BT

More stuff has come in. This time from sunsky-online.com. I’ve had good experience with them and I find them much more reliable than GLB, cheaper too.

The 2 main things here are the power distribution board and a bluetooth module.

The power distribution board costs USD0.86 plus shipping. You can’t really beat that. As you can see, it can handle up to 8 segments. The quality of the board is nice and it had nice big pads to attach your power cables to.

The bluetooth module was better than I had expected. Sunsky didn’t really have much specs on it, but their site indicated that the module operates at 3.3v. Upon inspecting the unit and searching around, I was pleasantly surprised that it had on-board regulation for 3.3v-6.5v. So no headaches of setting up a separate power supply when I use this on the quadcopter later.

In case you are wondering, the BT module reports back as a Linvor 1.5, and is actually running the HC06 firmware. This firmware is basically stripped down and only accepts a handful of AT commands. You could if you wanted (with a bit of technical know how of course), load a more powerful HC05 firmware in.
