"The FLiR developer kit is nice, but the 206 x 156 pixel Seek at $200.00 seems to provide a lot more performance for less money. Although I don't know about the cost of their developer kit yet. http://thermal.com/what_is_thermal_desktop.html"

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
