Another " Multi Button Mode Switch"

Posted on September 8, 2013 at 12:00am 3 Comments

At this point, more theoretical than practical.

Most TX's use 5V technology, Microchip has a nice 8PDIP, 10K, 256 step, device, the MCP41010, that will happily run on 5V.

If this were to replace a slider or pot on a TX, you would be able to hack any brand TX, even with limited tech skills.

So, this is an attempt…

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.

Hi Gustav

I had to hand over the project to an old university colleague of mine - who has more experience in the things that the client now suddenly wants (multispectral imaging and vegetation mapping). I wish I could be more involved!

Cheers

Hi All, I specialize in 300ha plus surveys, been in the business for 8 years, I do a lot of work for smaller multirotor operators whose equipment is not suitable for larger jobs, attached is a 2100ha job we have recently completed in Mozambique. Our processing is done by qualified land surveyors or you can process yourself, we can process using agisoft, photomodeler or pix4d, its up to you and your requirements, if you are a budding uav pilot we can process you images for you, generate contours as well as produce line drawings and add cadastral data from the surveyer generals office, Ortho rectified images with real worldfile data. email aerialinspection@gmail.com   cel:0767189211
