Aim
I plan to make a multimeter(a cheaper alternative to fluke multimeter or so) with logging capabilities and to produce graphical data about the variation in the input value.
Nomenclature
Raspchap multimeter =
Raspberry Pi 2
Che
ap Multimeter
Features
-->Measure up to 100 V ac and dc
Code:
(by using a voltage splitter to reduce 100v to 5 v)
:-->Resistance
Code:
(by using R=V/I)(0.1 Ω to 5 MΩ)
:-->continuity testing
Code:
(two separate GPI pins)
:-->NPN or PNP testing
Code:
(using 8 gpio pins)
:-->diode testing
:-->Min/Max and average recording to capture variations automatically
:--> Channel input for testing
Code:
(therby using 8 GPIO pins)
:-->Temperature
Code:
(by using a thermistor) (2 separate gpio pins)
:-->Logging the variation in input in graphical way
:-->with 4' display to display the readings
Code:
(separate gpio pins)
:-->3 years warranty
:-->Gaming while recording data from input
Code:
(using our beloved xbian os)
:-->Uploading the data to a server (to access it from any where around the world)
So you got a PC with all the capability of a mulimeter..
I have a couple projects that I'd like to try out on the RPi2:
1) Test building/running Liquidsoap on the RPi2. This is my ongoing effort to find a SBC that will run a Liquidsoap-based jukebox without stuttering. The RPi Model B could almost do it. For those that don't know, Liquidsoap is a scripting language for streaming media (entire automated radio stations (see AirTime) have been written in it). I have a homegrown jukebox that I'd like to move to a SBC. For more info on the language, see:
http://savonet.sourceforge.net/
2) Because the RPi7 is A7-based, it might be able to run the Xen hypervisor. I'm interested in seeing if the RPi2 can do it, with one of the VMs being the Win 10 (ARM) OS.

Hello!
I wanna build up a custom media center thing in a custom case that supports all media formats.
Here's my list what i want:
-IR receiver
-Bluetooth
-DVD drive
-Using HDD
(-DVB-T tuner)
-Automatically downloading my favorite series episodes from torrent
(-Configuring a NAS server for our documents, photos etc.)

not sure if we going to count this in as the thing you described is just basic XBian installation with some packages. All this was here for long and most of the people already using it
I hope to use a pi 2 for xbian and home automation/home security project.
I already have managed to program arduinos to send data from sensors to the pi using a 'domotica' system as well as one I have managed to do myself using NRF24L01+ radio modules and only arduinos.
Currently I get data from the greenhouse (greenhouse temp and humidity as well as outdoor temp and humidity, air pressure and light level (1 lux increments). I also have the fridge and freezer monitored (again with NRF modules) sending temp and humidity of each. All results currently displayed on a 20x4 and a 16x2 LCD display. Highest and lowest values are available and software filters for spurious readings.
Soon I will add highcharts and maybe some more to graph the data.
I have auto kitchen lighting as well with arduio that can be easily incorporated and am working on adding a function to turn on the amplifier when I enter the house to have music (and lights) come on when the front door is opened.
Adding more sensors inside (doors, windows, pir etc) and out (pir, bean break, uv levels etc) will follow to create a combined home security/ home automation/ media centre system.
It's taken a while to get this far, but I continue to search, read, learn and it's coming together nicely at the moment. I just need some more time and to look into adding a 'mono' based system alongside kodi in xbian and it could be finished in a matter of months.
Maybe it would be possible to have this all displayed within kodi similar to the weather plugins, but currently that's waaaay beyond my capabilities!
Skywatch.
Because of an error in our system we had to reset the poll to make things right. Unfortunately there wasn't a chance to save and move the data.
For this reason all is rested.
But no worries, there is plenty of time to vote again as we have extended the time.
You have 5 more days to do so.
We are sorry for inconvenience caused

Thank you; much appreciated. I spread the link like wildfire telling friends to make an account and vote and they said an account wasn't needed. Glad to see that's fixed.

So did I , I suspected that those votes which had been done without an account wouldnt be counted and that had a happened.Now atleast we have 5 more days of time...
Time is over.
We will make decision in next few hours and winner/s will be contacted
