Re: Wireless/wifi voltage monitor/battery monitor/ADC that works with Pi?

The problem with using the Pi as the "transmitter" is it would run even a huge deep cycle car battery down in a week or so. It would need it's own power station. I need something that is actually efficient. *shots fired*. I still have plans to try to use one as the "receiver" located indoors though....

Wireless/wifi voltage monitor/battery monitor/ADC that works with Pi?

I am looking for a sensor that can be wirelessly read back from, preferably, a Raspberry Pi or other generic computer. Proprietary wireless will be ok too if the price is right. I am trying to read back the voltage on a car battery at about 150 feet range. Here is a review of what I have found so fa...

Re: Choosing the pie for portability and performance

Awesome thread. I have gone through a lot of the problem that were mentioned here myself. Imperf3kt, that is a beautiful case. It really looks professional. My advice is to forget the keyboard because you will have many more challenges at a basic level than adding extra optional features. As has bee...

Re: Exar XR21B1411 driver

It should just be the name of the module you load with insmod minus the path or the .ko part. The top part of /etc/modules, if it already exists, has a brief explanation also.

/etc/modules will let you load the driver automatically at boot time. You should not have to be running make more than once.

Re: touchscreen between 3.5" - 5" for Pi Zero

First of all, I like where you are going with this. I would suggest to have an alternate day job if you don't already in case you run into a dead end. It would be virtually impossible to create a Linux mobile device to compete with Android or Iphone on an economic level because let's face it, most p...

Re: Extra short or right angle dupont connectors? For stacking components on top of GPIO

I just got around to trying this. Thanks for the tip on the IDC connectors and pulling off the clip. The ones I have do not have exposed metal when you pull off the clip. Still plastic but much shorter. I am a little worried about the thickness of the wire when it comes to powering a device straight...

Extra short or right angle dupont connectors? For stacking components on top of GPIO

I was hoping to find some extra short dupont connectors or premade wires with extra short dupont connectors already attached. I am stacking a battery (covered in electrical tape) directly on top of the gpio connector. I need to do this to save space. So I figured the easiest option to still use the ...

Re: Management of expectations

I am surprised that with so many knowledgeable people here we still have to speculate on what the problem is. Is there any of us here capable enough of finding the exact problem area within the Firefox source code? I am finding it harder than ever to use or recommend the Pi with the web page problems.

That is your DNS address. Is that the address of your router? If so, do the other PCs on the network also use that DNS address? If so, can you ping that address? If so, can you ping yahoo.com?
