@DougieLawson
Do You think I can buy an already made board with all the components (resistor, transistor, ...) to attach my fan?
Thank you!

Re: Power a 2x1.5v fan with 3.3v output

Hi, thank you for the answers. The "nmos" solution is far from my skills. I was trying to make something simple with the pieces I already have without soldering too much. I was looking also for an USB powered fan, but first I did not find a solution to switch on/off power over an USB line ...

Power a 2x1.5v fan with 3.3v output

Hi, I need to put a little fan into a furniture which is getting pretty hot in summer. I bought a little toy fan which must be powered via normal 2x1.5v batteries. I would like to switch on/off the fan based on the raspberry pi on board temperature. My idea was not to use batteries, but instead to p...

Re: The one feature needed for future RasPii

Re: Automated Plant Watering Web Interface

Hi, great stuff!
just a question , I do not understand what sensor are You using to measure soil moisture, humidity and sunlight, are they wireless or wired? To me the limiting factor of extending this to a number of plants is the cost of a good and low power wireless sensor.

Does the Magician can run on wooden parquet?
Or it will create lines in the wood?

Re: Cumulus - Open-Source Wireless 2.4GHz Home Monitoring /

Hi!
It seems interesting, but where are the prototypes?
Raspberry for the central server is ok, I also made it with 433MHz.
But I see only the Arduino Duemilanove which I think is not suited for long battery life and low cost.
Thank you!

Re: Logitech Wireless Touch Keyboard K400: Does it work for

Hi I am using RaspBMC and it works ok!
The only problem is (do not know if it is solved now) after a reboot sometimes the communication between the keyboard and the Pi is not working; the solution is to reboot the Pi again (unfortunately by removing USB power).

Re: RaspberryPi in Professional use

Very interesting post.
In my opinion the RPi would only need to improve a little bit of stability with power source.
No SD corruption as well or an embedded MMC for operating system.
And maybe an optional RTC clock.
Then it could be considered perfect!

What voltage are using for the transmitter board?? If 3.3v you may find the range is not as good as say using 5v. As for why your car fob has better range that's because a) transmitters work best in clear line of sight i.e. no walls or obstructions and the fact that you're holding the transmitter i...
