Initial Assembly of the Robotic WiFi Array
Log from Open Sky Anchor WiFi Drone Brings The GIG
The array has to be folded down flat when on the ground. After it takes off the antennas unfold and the make movements to track the ground antenna target. Remember the 5G antenna has a 30 degree cone of effectiveness and the 2.4G has a 60 degree cone...

Fitting forced air heatsinks onto the power supplies
Log from Open Sky Anchor WiFi Drone Brings The GIG
8 x 40mm heatsinks each with their own 12 volt 40mm fan originally destined for the hot end f a 3D printer. After fitting the heatsinks I do see some possible trouble connecting the DC power wires and the 220v ground tether after being assembled. O it...

Drone Weight In
Log from Open Sky Anchor WiFi Drone Brings The GIG
weight in 10 pounds 4 ounces. At 12.6 volts DJI estimates 600 gram thrust per motor, however we have upped the voltage to 15 volts even, but still below the 17 volts recommended maximum for the ESC / Motor combination tuned E300 system. I am considering...

New weight at around 8.6 pounds after swapping down to slim lines heatsinks. Next comes testing.

Power Supply Explodes , Whoa!
Log from Open Sky Anchor WiFi Drone Brings The GIG
Not that I like to highlight failures, but these power supplies popped way under their rated load. Everyone likes to see things explode though right?! one PSU seems to have a short on the Neutral Mains in line, it immediately pops the fuses...

2nd test after rewire, throttle up 25 percent
Log from Open Sky Anchor WiFi Drone Brings The GIG
This is the second test after removing the bad PSU from the loop to test equipment. It is raining outside now so we will have to wait till we can get it outside. There are many goals to this project and we are tackling them one at a time. This test is...

Current Strategy for Power Tether updated
Log from Open Sky Anchor WiFi Drone Brings The GIG
Though I do not post every test as boring as it would be, I am coming to the conclusion I need to alter the power distribution strategy. First is that peak wattage should come to about 1200-1300 watts with an average below 1000 in total. That being said...

Sky Anchor Flies for the First Time
Log from Open Sky Anchor WiFi Drone Brings The GIG
After a hard landing refusing throttle too quickly I surveyed the damaged. Luckily everything is 3D printed and I can print spares in a few hours.

Ver 2 PSU parts arrive from Digikey
Log from Open Sky Anchor WiFi Drone Brings The GIG
This is a quick comparison of the ver 1 power supply and the custom components we ordered from Digikey, take in mind I ordered one extra of every component in case of duds. So I should be able to be a more powerful power supply and still stay within...

Ver 3 8 degree arm weight in
Log from Open Sky Anchor WiFi Drone Brings The GIG
only a .4 ounce increases for a significantly stronger arm, I am considering drilling holes in strategic locations to shave off the other .4 ounces ,but keep the increase rigidity. Of course there is not need for the two bolts that were the hinges on...

New 3D Printed F550 Style Top Plate
Log from Open Sky Anchor WiFi Drone Brings The GIG
One of the goals in this project is versatile options for construction. Using a prebuilt frame works fine however a F550 frame to work with is not always available and tensions with China make getting cheap clones or even genuine parts harder and harder....
