Re: Breadboards, Astro Pi, and GPIO input

FYI, I have contacted element 14, the manufacturers of the Sense Hat (Astro Pi) and we are troubleshooting the issue; they don't know why it's doing this yet. I will keep the forum updated when/if anything significant comes of our troubleshooting. For anyone wondering, the magnetometer itself needs...

Re: Editing crontab -e via bash script.

Put the desired contents of the crontab into a file (let's call it "filename") Run crontab -u username filename crontab will read and parse the file, and if it's all good then it becomes the new crontab for that user. You beauty, thanks. That works perfectly. I did read the man page for c...

Editing crontab -e via bash script.

I'm trying to deploy several Raspberry Pi systems (running Raspbian Wheezy) so I am setting up a script to do everything to set up each one. I'm currently trying to automate editing of user pi's crontab (e.g. "crontab -e"). I understand pi's crontab is located at /var/spool/cron/crontabs/p...

Re: Breadboards, Astro Pi, and GPIO input

Hi Doug, Thanks very much for those last few comments which I only just saw today - apologies for the slow response. I'll give your advice a try in a few weeks when my work quietens down and I can get back into doing this. That said, I received a SenseHAT/Astro Pi in the mail the other day, and have...

Re: Breadboards, Astro Pi, and GPIO input

Actually, I think I have figured out the wiring. I found the product's data sheet which describes the operation of the sensor and from that I could figure it out. :D

Thanks again for your help, Doug.

Re: Breadboards, Astro Pi, and GPIO input

Thanks for that advice, Doug. I was originally looking at using this magnetometer: http://www.altronics.com.au/p/z6300-3-axis-micromag-magnetic-sensor-module/ ...but the instructions and wiring are for an Arduino, and I've got no idea what I'm even looking at. The reason for using this mag is that i...

Breadboards, Astro Pi, and GPIO input

Hi folks, I'm fairly new to all this and don't yet have a good understanding of GPIO or wiring in general (e.g. how do you even use a breadboard?). I've just bought two of the new Astro Pi units and want to get both of them plugged into a single Raspberry Pi 2 Model B unit. I realise one Astro Pi ta...

Automated setup of dozens of Pi. Or Pies. Pis?

Hello, Long-term lurker, first time poster; I have bugger-all programming experience so please be gentle. ;) I decided I needed to learn programming and electronics (because who knows where these skills may take me in future) so I threw myself in the deep end and bought a Raspberry Pi 2 Model B+, a ...
