Could anyone tell me what is the best way to send data from ArduIMU+ (non flat) to another board? I'm not sure about how to do that.Continue

Hi, guys!I noticed, on the ArduIMU+ Demo, that the GyroX ( Pitch ) value seemsto be inverted. I assembled it like manual explains (with all the chipsinside the "cube", with their top face pointing to…Continue

Canon DIY External Battery Adapter

Posted on February 15, 2014 at 2:00pm 16 Comments

It's been a while that I'm developing a camera control board and its software. That takes me hours sending commands for testing it on long shooting sessions. There was no battery enough here for such amount of tests... until now! ;)

Some time ago I've noticed a small hole on the battery slot of my S95. It is…

Computer vs Human. Guess who failed?

Posted on April 25, 2013 at 6:30am 8 Comments

Computer's mission: to drive a car, taking care of the road, signs, people, other vehicles and obstacles.

Human's mission: to pull the hand-break.

Guess who failed?

During a live demonstration the autonomous car hit Ana Maria Braga that is the star who hosts the TV show "Mais Você" in Brazil.

The car is part of a computing science graduate project from the Brazilian university UFES (Federal University of…

GeoTagging Images on Mission Planner

Posted on December 13, 2012 at 7:30am 92 Comments

Introdution

Geo-tagged aerial pictures are very useful for mosaic mapping as well as the creation of accurate 3D models from a terrain.

Michael Oborne added a great tool for injecting GPS data on the EXIF tags by using APM's telemetry log from a flight.

Fala Sandro, tudo bem?
Legal ver um brazuca por aqui, ainda mais envolvido com um dos projetos.
Eu conheço o DIYDrones há algum tempo. Também comecei a brincar com o Arducopter antes dele integrar ao DIYDrones, mas não terminei de construir o meu modelo.
Queria trocar umas ideias com você sobre OSH, Arducopter e o DIYDrones. Tem um GTalk ou algo do tipo?

Ola Sandro,
visitando a pag do fahpah encontrei dois kits a venda (o segundo $ 499 e o terceiro $ 579) pelo que entendi a diferenca entre eles era somente que os componentes ja vinham soldados e testados, e os programas gravados em cd, seria somente isso?
Sera que vamos ter um representante aqui no Brasil ???

Good morning. As everyone knows, the spots and DIYdrones forum should be posted in English. We also all know that due to the variety of subjects is complicated participate in blogs and help those in need. As I'm assembling more than a year my autopilot, having faced all sorts of problems, I propose creating a more direct channel of communication between members of DIYDRONES in Brazil. So, please consult the other Brazilians on how this tool would be interested and if we have. grateful for the collaboration

Hi Sandro, how are you? Congratulations to your effort on diydrones comunnity!

I would like to present with you the weblink of a project I having with my fellows. The project is called Team Abequar,A Brazilian team we are building a platform to be used in the next UAV Outback Challenge - Search&Rescue. We already passed Delivery 1 and we are doing  tests for the next delivery. As a core autopilot and flight termination we are using APMs. Please visit our page www.abequar.net.br. There you will see about Abequar and Super Abequar too.

kind regards,

Omar

Sandro,
Meu minimosd nao functions mais, acho que o problema tem a ver com a fiação da alimentação , que quase tudo mundo tem problema.
Você poderia clarificar qual e forma mais segura, de connetar o Osd,?
12 vcc no video sim o não
Terra comum sim o não
5vcc comum sim ou não
12 vcc no video isolado ou conectado? (Só sinal)

Muito obrigado
Gustavo

Sorry for the Portuguese ,
In English
Sandro,my minimosd seams to be failed on the analog video section,
I guess the problem has to do with the power issues, most of the people face the same issue.

Could you please clarify what is the "safest" way to wire analog and digital power,
12 volts on the analog section , yes or no
Common ground , yes or no
Common 5vcc , yes or no
12vcc pin, connected or isolated,

I have no problem on using one or two batteries,

Additional question, do somebody knows If it is the video chip the one that normally fails, or is it the voltage regulator, and then it could be repaired?

Thanks

Sandro,

do you have any recommendation on how to    power the minimosd, without risk of burning it during process _?

thanks

Olá Sandro

estou com um problema para fazer geotag com logs onboard da apm, o radio tava mal posicionado e perdi a telemetria, mas acabei optando por continuar a missão. tem como você dar uma olhada e ver se deu bug no log ou eu que tô fazendo cagada mesmo? postei o problema aqui: http://www.diydrones.com/profiles/blogs/geotagging-images-with-mission-planner?xg_source=activity&id=705844%3ABlogPost%3A1054809&page=5#comments

valeu, Ricardo.
