Great deal on a 3 axis gimbal with Alexmos controller

Posted on June 26, 2015 at 4:00pm 23 Comments

Just had to tell all of you about this $59.95 three axis gimbal deal on EBay:

This seemed like a great deal and looks to be identical to DYS Gimbal on Hobbyking which is $200.00.

I got one and quality appears excellent though I haven't tried to use it yet (I will probably get…

My thoughts on the state of affairs.

Recently a local radio station asked me to comment on an interview relating to the current status of "drones".

I am enclosing the letter I sent to them declining phone interview for the reasons specified, but putting my "opinions" in writing instead for them to use as the…

GoPro 4 is Here - Sort of!

Posted on September 29, 2014 at 10:30am 36 Comments

GoPro is finally announcing the new 4 Silver and Black:

It , of course has the new 30fps 4K and - not surprisingly costs $100.00 more than the last one so now $499.00.

Probably using the new Ambarella 9 chip, but no mention made of built in electronic image stabilization…

New 1 at a time ESC calibration method for PX4 or Pixhawk

Posted on June 28, 2014 at 2:47pm 3 Comments

One of the Problems with the PX4 / Pixhawk is that it uses a PPM-Sum receiver which when so configured may not work at all for the normal receiver based method of one at a time ESC programming.

And especially so for 4 in 1 ESCs.

The one at a time method I have developed uses the Wikis…

Hola que tal Gary sabes el hadware que necesito para hacer mi drone Cooperativo

Hi Gary,

Just a thing on shipping rates (from your comment). I was also mad because of high shipping. I sent support an email and they shipped the parts for free through standard mail! I got it in 2 days ( I live on the east coast). There is a size limit though, can't go above 13 oz, but for small parts its fine. Oh and btw, when you email them, ask for Lorena, it may take a day or 2 more because of her work hours, but she's been amazing with shipping like this.

 

Sorry this is the only way I could contact you!

 

Michael

Hi Gary,

Re: Fire Cape

Thanks,
