Re: Help with Steampunk Rifle with Raspberry Pi 'Scope'

It's fairly simple to autolaunch a python script at boot. I did something similar for my Aliens Motion Tracker project. First you'll want to create a shell script in the home directory, let's call it launcher.sh In the script you'll want something like this: #!/bin/sh # launcher.sh # Navigate to scr...

Re: Desoldering station/gun recommendations

Re: LAN Lab Equipment output to Wireless network

Yes, it woud be quite straightforward to set up a Pi as a simple Network bridge. You just need to enable IPv4 forwarding and configure iptables to allow the connections, both of which are very straightforward to do. You can also chuck in a couple of wireless adaptors, set one to connect to your wire...

Re: IP Tables settings do not stay fixed

Actually, I did try using the iptables-save option and it appears to work great. The file with the rules in it appears and works wonderfully.

How-To: Pi as an Active Directory Domain Controller

I recently found the need to set up a test domain for work purposes but couldn't get access to a proper Windows Server box so since Samba 4 can act as a proper AD controller I decided to give it a go. It took a few tries and several card formattings before I got the process down pat so I thought I w...

Re: IP Tables settings do not stay fixed

I had the same problem while trying to set up my pi to route from the wired to wireless network. I got round it by installing the iptables-persistent package. Just set up your rules manually and then install the package. It will ask you to confirm you want to keep the current rules then make them pe...

Re: Colonial Marines Motion Tracker for Pi

Interesting idea.
Possible to mount the sensor in the jobo minilight attatched to the front of the device.

I wonder if I I could attach two and use them to triangulate positional information as well as range.

hmmm.

Which GPIO pin do you have the signal pin on the IR module plugged into? Lirc defaults to accepting signals from GPIO 18, to override this you need to edit /etc/modules.conf and put the following in it: lirc_dev lirc_rpi gpio_in_pin=11 where lirc_rpi_gpio_in_pin points to the gpio pin you have conn...

Yes, that would work :) but the -c option needs a parameter saying how many packets to transmit, like "-c 1". Also, I'd consider adding a "-W 1" to make the ping time out after one second, which should be enough. <sigh> you're really making me work for this aren't you? :P OK. How's this: #!/bin/bas...

Just plug a Standard USB to Micro USB cable from the Powered Hub to the Pi. Make sure your Powered hub can actually supply enough juice to power the Hard Drive though.

Re: XBMC \ Openelec Hard Drive Help

I would strongly recommend against powering a USB hard drive from the PI, USB hard drives tend to be power hungry and could blow the microfuse on the Pi.
Best to plug it into a powered hub that is connected to the Pi.

Re: XBMC \ Openelec

I would check the compression on the mkv files. I had a few that wouldn't play and it turned out they were compressed with the old Xvid codec which the PI couldnn't handle. I had to re-encode them to h.264 before they would play.
