Re: Sainsmart 16x2 I2C lcd

You Sir are 100% correct. I swapped SD card and the hardware to another Pi and everything is working. My son grabbed it before I started having issues, so I'm wondering why it's no longer working. I don't see any visual defects... EDIT: I take that back, I hooked everything back to the original Pi a...

Re: Sainsmart 16x2 I2C lcd

So I was using the code that Denis posted and everything was working perfectly until I shutdown my pi. Now the characters that show up are just random and I can't figure out what happened.

Re: data collection and storage with pi 2

As long as that data is coming in at 3.3v you can use the Pi. Otherwise you'll need a logic converter.

Re: Which GPIO pins are 0V at and after boot?

That's not the correct way of doing this. You should be using ESCs (Electronic Speed Controller) which require a special sequence in order to ARM so to prevent your motors from starting up in case you turn on your TX with the throttle stick UP.

Re: Automatically open a changing URL remotely

Well, there are multiple ways of doing this. You can use sockets to have your Pi listening on a port and your chrome extension send the stream URL to the Pi via Socket connection, or setup the Pi as a web server and have a PHP page which accepts GET requests through which you can send your Pi the UR...

Re: Raspberry Pi Mail Forwarding

Re: Transmission daemon slow and hanging

I love transmission and I haven't had any issues until recently.

I realized that I installed tinyproxy on my pi and removed it and now transmission is back to it's regular self.

I suggest you guys check what might be interfering with transmission.

Hope this helps.

+1 for using wifi.

Doubt you can get decent speed for video stream via BT. Wifi you'll have better range and more bandwidth.

Re: battery source

Well your pi will need 5v @ 1A so that's your minimum.

Really hard to tell what a good power source for you would be since you didn't disclose what type of motors you will be using.

Re: How do you fade in videos using Raspberry Pi?

Hardware?

Wire the "brightness" button on the monitor to a Pi GPIO and have the pi adjust the monitors brightness.

That's a crude way to do it.

You also need to send packets to sync the devices before you can transmit data.

Re: Aerial Photography Camera and GPS

You don't really need that USB cable, unless you don't have any wires.

You can just wire that GPS directly to Pi's serial pins.

I don't know how you would add the GPS data to an image, whenever the Pi takes a pic, modify/add EXIF data with current GPS coords?

Re: Solar Power, intelligent control using Pi

Why don't you just store some electricity at your house (in batteries)?

Measure how much energy you need with a Kill-a-Watt and figure out how many batteries you will need for you to run your stuff off the grid, no need to rely on the weather.

Re: Read value of a pin in java

What type of sensor are you using to detect light?

More than likely the sensor is analog which the Pi would require an ADC.

Your pi works with digital signal (either a 1 or 0) unlike an arduino which can measure the actual voltage (analog).

Hope this helps.
