Hi yet again, guys.

besides the search system for UAS, answering questions in ibeacon post, we've been developing some new designs.

Here are some bakery right off the DIY bench for your attention, dear pilots, developers and implementors.

These naked babies, tiny PCB modules are instances of Switch mode Constant Current High power Buck (step down) converters, made to deliver up to 3A of solid constant current (with no flicker) to a LED module like good-old Cree XML-T6 and to be dimmed up to 20 kHz pwm high frequency or just switched logically with no drain on or off as well.

Some details I tried to cover in short video on 3A LED Driver

One of these modules connects directly to your 3 or 4 cell LiPo battery and feeds up to 4 High current LEDs connected in series from 4 cell LiPo battery or up to 3 from 3 LiPo cells

The lower one is three channel Constant Current Buck tuned to run with an RGB powerful LED like one in the middle of the photograph. This three channel one was implemented to serve as a state and event external indicator for an autonomous system.

Cheers, and you're welcome with any questions you like, as always.

Hi folks!

I would like to post some autonomous algorithmic bidirectional radio search system production design approximation stuff here.

Please, you are welcome with any questions you may find of particular interest in this regard.

p.s. My apm 2.0 dates from 2011 early preorder and it's still in touch yet after all it has gone through.

Thank you, maintainers, testers, 3dr team as well as all people involved, that was and still is and no doubt will be lots of further fun.

setup disassembly check

This is actually 3^rd time after two manual mode unsuccessfull maidens due to prop fails on this setup.

The basekit is x-uav

it has v-tail mixes allover,

so it moves two channels mixing them.

Now I begin to see too many possible failure points,

to eliminate them all entire being is barely enough)

The motor is one third too low kV,

Booting up 9X makes 3 secs of aileron limit hit pwm.

(however after recollecting link from control Tx does not affect)
