Ive been looking into doing this also, but using the existing laptop battery so it didnt look too out of place having extra batteries or spots missing. This is what I found to help with that: http://linuxehacking.blogspot.com/2014/03/recharging-and-reusing-acer-laptop.html They look like it just has...

cae2100

yea, I just used it with the arduino software to write code on, and it does good for that, It's a little slow, but when your just writing code and such, it works perfectly. I showed eben it in september and he was really interested in it. I dont use it much anymore due to having my main laptop fixed...

check this out: http://www.techrepublic.com/blog/linux-and-open-source/drive-and-partition-backups-with-dd/ If you wanted to duplicate an existing drive to another, you would obtain a drive of the same (or larger) size. Assuming the drive to copy is /dev/sda and the destination drive is /dev/sdb, fi...

hi, I made a case that was low profile for the rpi B version, but it allows access to the GPIO pins and everything, just like as if you didnt have a case, so plates/shields fit on it perfectly and are still usable. I know you can access the GPIO on the normal RPi B pibow version, but you need a cabl...

I usually use xmms for playing music/audio files/media streams on the raspberry pi, here's a guide on how to install it: http://cae2100.wordpress.com/2013/03/28/xmms-for-the-raspberry-pi/ then just use a thumb drive or whatever and you can just play it off of that, or you can copy it over and play i...

most motherboards use generic pcb holes layout, so like your inspiron, you can replace the mobo with a standard mini-atx mobo, and those with the processors usually run 40-50 dollars anymore, that's why I said it was cheaper to replace the mobo. I work on computers for a living and have done that ma...

cae2100

well, you can get the external enclosure electronics and hook the stuff up that way, like hdd/cdrom drive, but idk how well the cdrom drive would work. The only thing is, the rpi is designed to run from an SD card, not external harddrive, and you probably noticed by now that it wont run the normal p...

cae2100

looks like you just need to take a 2.5 hdd enclosure electronics and screw everything on there, all hooked up to the usb on the built in hub. yea, that part doesnt really make that much sense to me either, but I guess it's better than just the sd card for space. Im sure you can put something there i...

cae2100

from this picture, there's ethernet, audio, video, hdmi, barrel jack for 12v in from laptop charger it looks like, 2 usb, a serial port with db9 connector, and what looks like a db25 (parallel port) connector that is connected to the GPIO pins. It has 3 additional usb plugins inside for your wifi ad...

cae2100

holy crap that is awesome, I can see me getting one of those as soon as they're out of kickstarter. Only thing I wish it had was vga connector on it also, then I'd have to replace my desktop computer all the way with my rpi.

(not like I dont use the rpi for most stuff anyhow)

cae2100

I love the idea, and will defenitely be building a few of them for the rpis I have around here. Great idea for xbmc system that sits behind the tv, those are a pain to keep unplugging/plugging in, much easier to just put a button and press it to start it up, then it shuts itself down automatically :...

cae2100

for what you need, it sounds like you should try out archlinux, there is a distro on the main page for the download for it. Designing the kernel and filesystem is a bit difficult, much more than most people would even want to try. If you feel brave enough, I have a guide on how to design a kernel fo...

cae2100

have you checked your bluetooth devices to make sure they're discoverable? Usually if it's a cell phone or something like that, they will only stay discoverable for 3 mins then dissappear again.

cae2100

there are a few small usb gps modules that Ive seen used with the raspberry pi, and same with 3g dongles, just plug them in and search through the forums here, and you should find everything you would need to know to get updated. There is python code and such to upload sensor readings and such from ...

cae2100

first, try to do "sudo apt-get update && sudo apt-get upgrade" to get rid of the chance that it's just an old version, and here's a short tutorial on the GPIO pins and python: http://cae2100.wordpress.com/2013/01/10/short-tutorial-on-raspberry-pis-gpio-pins-in-python/ hope that hel...

cae2100

the indentation error is from things not being indented as they should be. try uploading your whole code using code tags, and Ill go through and fix everything for you and see where the issues are.

cae2100

try using search on the forums here, there's a ton of people that have done the same thing already. This is the first good result I found:

maybe just hook it up to the windows computer and try to change the baud rate somehow to something standard. From looking around the web, it seems that the issue is a limitation of pyserial and not being able to use the non standard speeds.

cae2100

128k isnt a standard speed, and in all honesty, Ive never seen anything that's used that baud rate. You may want to try 115200 instead since that's standard baud rate on stuff like that.

cae2100

most special function keys, to the computer, arent actually a single key, but a combination of keys. Like the email button may be ctrl+alt+F8 or something like that, you'd just have to google it. If you found the combo for the key you want to assign it to, you can use openbox configuration, like thi...

cae2100

first, try editing your post by removing your code and re-pasting the code from your program inside of the code tags, it makes it much easier to read and helps rule out alot of the issues that most people have with tab spacing in thier programs and diagnosing issues like that. Second, just looking a...

cae2100

you may not have pyserial installed, some distros dont have it installed by default that Ive found. to install it, just type/paste this in in a terminal window/command line: sudo apt-get install python-serial That seems to be your issue. Also, the varable that you're using for the serial in your pro...

cae2100

be careful because python is case sensitive. use import serial instead of import Serial also, you assign the serial port in this line here: ser = serial.Serial('/dev/ttyACM0',9600) just change the "/dev/ttyACM0" to whatever one you want, which ttyACM0 is standard for arduino uno, or ttyUSB...

cae2100

pyserial is very easy to use, and will serve your purpose very well. This is a good start on how to use it with examples and such: http://playground.arduino.cc/interfacing/python As for saving stuff to a file, here's a small example script that I keep around to help me remember saving/loading files ...

cae2100

Ive seen this one around while researching the 3d printers to buy, but due to it still in kickstarter and the community as big as I would have prefered, I ended up going with the printrbot jr kit, around same price I believe, and has an insanely large community.
