Though not MySensors related, I thought I'd post my latest build that has been consuming a lot of my time lately. This is the main reason I haven't been on the forum much lately. I bought a drone kit recently. Here are some pics from the initial assembly:

Since the initial build I have flown it and from a hard landing broken one of the cheap plastic legs that it came with. I designed a replacement with my 3D printer and some 1/4 inch aluminum rod.

Here are some pics at it's current stage. I have designed and printed some prop guards and a few other add-ons:

I have also designed and built a small servo based 3 axis camera gimbal. The controller was built using one of my spare 5 volt pro minis and an MPU-6050 accelerometer. Still working on the parts that will attach it to the drone, and I still need to pick up an FPV camera to attach to it, but a simple FPV cam is cheap.

@nca78 I did go with those and it seems to be working great.

@neverdie That has got to be one of the smoothest benchies I've seen.

@neverdie If you have an E3D V6, then you are running a J-Head.
Not sure exactly why they call it a J-Head as it looks nothing like a J shape...

I assume you just swapped out the heat block? The Volcanos are like a standard heat block only stood on end.

@neverdie Are you using an E3D J-Head with your Volcano hot end? I am in the process of working on an E3D clone J-Head setup with a Bowden extruder, but I went with the standard heat block and not the Volcano.

@simple Do you have a link to more information about this part?

@sundberg84 I have tasker on my phone. I will have to try this. I had some issues on one of my previous phones so I didn't use tasker as much as I thought I would. I woner if it will work better on my Samsung Galaxy S8+. It would also be nice if I could get geofencing working too.

@sundberg84 if what @Yveaux says is correct, wouldn't the phone constantly connect and disconnect and trigger tasker?

You can also use 3 AA batteries in a configuration like this:

I have noted values for rechargeable batteries as these have a nominal value of 1.2 volts vs 1.5 volts for an alkaline battery. The 4.5v side would be to power the PIR and the 3V side to power the pro mini.

@neverdie Can you run a stock GRBL build on RAMPS?
