  • Reman: I did double check it with a metre (Mainly because I knew if I didn't check the polarity this would be the time the manufacturer had gone off script and put the negative in the middle of the coax) and felt slightly cheated because it was only making 19.7 volts. :)

  • Bajadre: yeah heat and wring never a good thing only a matter of time :(
    January 04, 2019, 10:12:57
  • Bad Raven: Well, it should! Rated for 24v. Be careful, have you checked the PSU output?  Many psu that (say) are supposed to be 12v actually output 16-18v. Is your 20v actually less than 24v??
    January 04, 2019, 08:41:14
  • Reman: Just modified the cable on a 20V 7A PSU to connect to my TS100........ It.... Erm..... Heats up a bit quicker than it did on 12V. LOL !!!

  • Reman: I didn't try to taste it, but it gave off that kind of smell that gets you in the back of the throat. :)

Not posted for a while, been sailing... We had a new crew member join us and she brought a DJI drone with her. I'm an old-school Arducopter user (well, was 5 years ago - not done anything much for a while) - so I was interested to see a DJI drone up close for the first time. However, this drone had a problem - fogging lens - meaning it hadn't been used much. For example..

We were on the boat, in Huon Reef, north of New Caledonia. Its pretty remote - the only way to get there is by sailing. In desperation, I remembered I had Gaz's e-mail address, so I fired off a quick e-mail to see if I could cheekily use him to google for me. Like a star, he delivered! We thought about it, and went a bit further - I ended up building a small vacuum chamber. We're used to improvising fixes on the boat when we're way offshore. In this case, i took the vacuum pump I have to fix my fridges, and a sealing bottle for blood testing strips, heath-robinsoned it together and ended up with this:

I dismantled the DJI gimbal and got the camera unit off, and put it into the pot and ran the vacuum pump for a few hours whilst we sailed from Huon to Chesterfield reef (2 day sail). Once vacuumed, we left the camera in a pot with silica gel and some rice (for good measure).

Once at Chesterfield reef - which is really in the middle of nowhere, we reassembled the drone and did a test flight. Miraculously, it has fixed the issue! We've done a number of flights over the following week and the lens has remained fog free. I was given free reign with it, so naturally had to take a piccy or two of the boat...

So Gaz - thanks for the help! Totally appreciated by myself and our crew Phoebe. Less so by my wife, as she now sees another expensive hobby re-ignited :) She was hoping sailing and diving was enough :) :)

We sailed into Australia yesterday (3 days from Chesterfield). Crew and drone departed, so I'm cruising the 'used drone' ads. We're here for 6 months of cyclone season and a small re-engine project. Gotta love boats!

I should probably mention that this was a DJI Mavic Pro, and wow have things moved on in 5 years. It was very stable on take off - though to be fair we were in ideal conditions with almost zero wind (hence the gin clear water). I never tried 'sport mode' or whatever it was - last thing I wanted to do was stack the drone we'd put considerable effort into fixing ;) Flying around in the 'normal' mode was very sedate but got the job done. Video footage from a high hover was incredibly stable. Very impressed.

The controller/tablet combo worked really well - so much so that I can definitely see myself with a DJI drone in the future.

We had some other minor issues - a poorly attached prop came off and caused a slight on-deck crash which damaged the gimbal. Surreptitious bending of a metal component sorted that. The other problem was Phoebe's attempts to fix the fogging had resulted in rice getting everywhere inside the drone - so that took some cleaning out. Fortunately I had my torx drivers from my arducopter days, which may disassembly much easier. And boy do you miss you-tube when you don't have it - it makes it so much easier if you can see a video of someone else doing it first ;)

Hah, I'll try :) Though as you (now) know, when we're offshore we have a very limited connection - certainly not up to posting videos!

Its interesting that I can get 4G data far cheaper in places like Morocco, Fiji and Vanuatu than I can in Australia or NZ....

Anyway, thanks again :)
