"I humbly suggest again to look at just using diodes to OR your supplies/batteries ?
Get practical, take a diode like 1N5819, run 500mA through it, measure the drop.
And it can easily handle peak currents up to 10 A ! Looking at Dean's circuit,…"

Gustav Kuhn commented on Gareth Rens's blog post Backup system for BEC"Gareth.,
You don't want to use relays.
Switching them introduces spikes, brownouts, etc, etc.
Much better to OR all your supplies using Schottky diodes, with a fairly large capacitor on the final output.
In fact, on most of my stuff I use…"

DroneZone is part of the same enterprise, but you are welcome to change the hyperlink to DroneZone.
Apologies for the confusion."
ModeratorMorli commented on Gustav Kuhn's blog post 3DR Quad Build
"@Gustav
Is that not a correct name of the supplier and link? I added the hyperlink in the original post."
Wessie commented on Gustav Kuhn's blog post 3DR Quad Build"thanx Gustav!Actually the technically correct link would be www.DroneZone.co.za, but thanx for the punt!"

I was approached by Wessie from Drone Zone to do a build log on the latest 3DR Quad.On the kits he now stocks....What a pleasure, the only soldering I had to do, was fitting Deans plugs to the speed controllers, and remove the Deans on the PDB, to fit a XT60, since all my…See More
Gustav Kuhn replied to DaveM's discussion My first question in the group ArduCopter User Group""The money I have access to is restricted to buying stuff - and can't be used to pay people."
Then, "buy" a ready built system, pilot included?
What will catch you out, BIG time, is actually flying the thing.
In our club…"
Gustav Kuhn replied to DaveM's discussion My first question in the group ArduCopter User Group"Sounds like your best bet would be to get someone with a working system to come and get involved/demo ?
$800 sounds like it should buy food and a place to sleep for such a person ?
Six weeks is rather a steep hill to climb, to roll your own........."
Gustav Kuhn commented on Gustav Kuhn's blog post The safety thing, again.Warning, graphic images"Yep, looking at the pics from start wasn't too bad, but the tip.........
The dude in the pics might be at our annual fly in next month, I'll try to find out what went wrong, might learn something...... IMPORTANT !!!!"

I try to make a point of either tying down a largish aircraft, say .60 size and up, to something, or get somebody to hold it in position.
I said, try, have the scars from even smaller ones "getting away"
However, this dude…

Gisela & Joe Noci said… Hello Gustav!!!!
Yep, thats me! My goodness, that is a lifetime ago I still remember when we stayed in the hostel and you went to do your radio amateur exam in JHB, in town, that evening!
That is all a very longtime ago.
How are you? I have moved to Namibia , 5years ago, had enough of Gauteng and everything else - was with ATE for the last 18 years or so. Now live next to the sea, in a quiet and peacefull place, playing UAV's...
Very nice to hear from you. Maybe we can make a sked on HF, if you are still into that!
Keep well.
Kind Regards
Joe

Well, as least you are out of Gauteng, but you left early on anyway - good that you never came back! I was with a commercial company for about 2 years after Atlas, then went to Andromeda, doing BIT Slice processor copies of VAX computers, then went to ATE, did Rooivalk mission and weapons systems, Pilatus trainer avionics, lots of UAV work, big stuff - 160kg plus, etc, etc, and left them 5 years ago. Now I am having fun! Also busy now with a big quadrotor, own design, using helicopter blades 750mm diameter X 4. Hope to carry a 2kg camera for 1 hour...
Well, I hope if you 'die' there it is in the far distant future!
Keep well Gustav.
Regards
Joe

Hi again Gustav,
Have seen you guys and Big Bertha, etc. I did something similar with a Lanyu 100 - check on DIYDrones blog for Nampilot and HORNBILL - also GUPPY and SurVoyeur, our latest commercial product - having far to much fun for two people out here in Swakop!.
How things going?>>

Hi Joe,
So envious of your successes !
Big Bertha has been mothballed, the client realized that they required a certain proficiency with operating RC equipment, that they did not have.
I don't get much chance to RC here lately, other interests, work, the weather, all conspires against me !
I've looked at your website, very impressive.
