What issues did you have? That's my blog referenced, recently validated and edited the page to make sure it works with the latest Rasbian Pixels

In order to take a picture you'll need the focus and shutter buttons shorting to ground (*but see below). As discussed, an opto-isolator is the safest option, but it isn't really necessary. See what David Hunt did here : http://davidhunt.ie/wp-content/uploads/2013/01/Shutter.png Note that you'll ne...

I have a Pi Zero, and plan to use it as a remote shutter release for my camera, for doing time-lapse etc.. the lead for my Camera (A Sony Alpha DSLR) is remarkably simple with 3 pins; 1 Ground 2 Focus 3 Shutter release Focus is achieved by connecting pin 2 to pin 1, and a release is a connection be...

It's an A550. It does have ir but I want to be behind the camera..

jimmyeao

Yes, I think I need to investigate what an opto-isolater is, and how to use one! My goal is to have a pi-zero and associated electronics in a small case with a lead and a display, that can be controlled wirelessly from a laptop/phone/tablet. I could by a ready made device cheaper, but wheres the fun...

jimmyeao

No voltage is used in theses systems , so I am trying to understand how I can use the pi zero to achieve this? Wrong. You don't know what voltage is used, so you would need to use something like an opto-isolator to prevent it frying your RPi and/or frying your camera. Does the camera have a USB int...

Sadly this seems to be broken... 404 error after the install trying to access the /froxlor/install/install.php
this is because the froxlor directory is in /var/www/froxlor instead of /var/www/html/froxlor

jimmyeao

Just fixed it... How? Replaced my Home Hub :/

jimmyeao

This makes me wonder how you connect via ssh. You seem to be using a hostname instead of an IP address? In that case, try connecting to the IP of wlan0 instead. The theory behind this is that you are using a hostname which is registrered through dhcp-dns integration on your router. Since the Pi has...

jimmyeao

OK, so I am a step closer... I plugged an actual screen/keyboard in to the PI so I can see what is going on, and so far this is what I have found: WLAN 0 is coming up and obtaining an IP I can SSH from the PI into other systems, do apt-get update etc no problem. If I try and SSH into the PI, I get t...

I have now changed my files as per below, and now the Wireless doesnt connect at all . I should point out im using WPA 2 on my router, a BT Hub 5 ifconfig -a output: eth0 Link encap:Ethernet HWaddr b8:27:eb:ee:76:24 inet addr:192.168.1.139 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING ...

jimmyeao

I think the config you linked to in the first post is a bit strange, try this instead: /etc/network/interfaces: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp /etc/wpa_supplican...

jimmyeao

it sounds like the distro you are using doesn't support apt-get or aptitude.

What flavour of Linux is it? Any particular reason you arent using Raspbian?

jimmyeao

using the Edimax EW-7811UN - as I say, it connects just fine with the ethernet cable plugged in, I can even SSH into the IP of the Wireless. When I unplug the ethernet, SSH drops, however my router still shows the wireless as connected, leading me to think that maybe it is trying to route responses ...

Using a 2amp PSU, so no issue there,
The dongle shows up fine
The blue light is on (Flashing as you would expect)
If I disconnect the ethernet cable, the connection drops..
I'm just re-imaging the SD card to try again from scratch, will post up my config shortly..

jimmyeao

I know this is an old post, but I am having the same issue, however I'm tempted to believe it to be a routing issue on the PI. Why? Because I can see the Pi wireless associated to my wireless access point, and see the ip address it has been assigned. I can only surmise that it is trying to route out...

Bump... Anyone? Im stumped...

I have tried setting up WiFi on my pi using wicd-curses (Just didn't work - disconnected me and had to reboot to regain access) and by following this guide here: http://kp4tr.org/?page_id=320 If I leave the ethernet cable connected, wifi will work. If I remove the ethernet cable, WiFi Stops working ...

Hi Pete, hows this going? Im looking at a Piface also, I want to create an RC Rover. My plan is to print the plastic parts with a 3D printer I have, then bolt on the other bits as necessary, ot possibly buy one of these What did you use as a chassis etc? I'm also very new to python, but i am fairly ...

Well said

Worth mentioning, there is a Skype addon for XBMC, not tried it though!

I think some of the analogies used here, and more worryingly, the way others extrapolate ideas from them based on their own perceived intelligence is worrying.. Bottom line? Whether you use an IDE or not, your still a developer, (in other words e-n-g-i-n-e-e-r-s) Turning a computer on and running a ...
