Re: hacking a hozelock water valve with raspi

ok some quick advice. anything that has a coil like this will give back emf into the circuit . You can totally protect the pi GPIO with circuits like opto-isolators which in turn control power MOSFET SCRs that will energize the relay. You need to protect them from the back emf with a capacitor . Als...

Re: Greenhouse/seedling automation project

a couple of other things . If you are running headless and off the internet you can get a cheap Clock module that plugs into the PI. that and setting up cron jobs with rsync and other cool commands should keep you busy learning for a bit. I generally program in C or C variants C++ and C# these days ...

Re: Designing a Printed Circuit Board on a Raspberry Pi

Diptrace Rocks. I never did try Eagle , a friend of mine has. But designing with Diptrace is quite easy after a while and it's actually worth investing in getting a copy that can do larger projects :)

Re: VLC with Cron - can't figure it out

to run a cron job you need to use the syntax:

* * * * * * bash -c yourcommandtorun

In other words 'fill in the date and time fields' and then use bash -c to run stuff that you normally run in a terminal

package management tool

What package management tools are people using on the Pi when they want to release their c++ projects. I could do it fairly easily in Visual Studio but haven't found a package management system for my projects that were written on and built for raspbian O/S.

A couple of questions .
What environment are you writing your c++ code in ? (Eclipse , Visual Studio, QT etc...)

Re: calling integer from sub window

you can define a variable in the sub window header .. Usually you create and then use public get and set methods to access that variable in order to protect it. This works with all kinds of stuff besides integers. Then in your mainwindow you can do something like the following pseudocode : subwindow...

Re: wiringPi undefined Reference

I managed to get it all going with QT c++ . This gives you a drag & drop environment to create windows & widgets as well as interface with wiring pi GPIO . Are you using Eclipse or Visual Studio to create c++ instead of QT ? I Can't help hook into those IDE's :)
