Re: Markdown - customisation

Excellent, that will save a lot of leg-work. I may combine it with comments so that it is seamless within markdown.

Many thanks!

Re: Markdown - customisation

My thinking is to be able to select between different options, by using a program to rebuild the text by selecting various tags (i.e. you would be able to enable a section of text which includes setup information, or remove it if it wasn't needed). This would allow you to generate customised pdfs et...

There are two places that need to be changed to disable raspi-config

Remove the script from profile.d if it exists

rm -f /etc/profile.d/raspi-config.sh

Remove the entry from /etc/inittab that ends with RPICFG_TO_ENABLE
Many thanks, I'll be sure to try this out!

Markdown - customisation

Just wondering if there are any Markdown gurus out there who know if there are any programs which allow you to customise a markdown document based on tags or similar. The idea is as follows: Top of document you list a series of optional tags. Within the document you have tags around blocks of text. ...

NOOBS - auto start of Raspi-Config

I`ve been setting up some systems which automatically configure everything on the SDCard, however I`ve now got to the point where "raspi-config" autostarting following an install isn`t needed. Q1: Where does NOOBS kickstart raspi-config from? I can then stop it running if I need to. Also, on a relat...

So far I've tried to format them using markdown so I hope they could fit in with the foun...

Possibly an Arduino in combination with a Raspberry Pi would be suitable, with the Raspberry Pi taking over the role of the PC in your example.

Re: Dream projects?

I think it isn't too far away.

Although,...

Yes from their descriptions and images looks like an IR grid or pattern, and some fast processing to make sense of it.

Re: Low voltage on test points!

[With the Pi turned off and disconnected from anything] Locate the Polyfuse, green little component on the back (see the Raspberry Pi component map that was posted on the main Raspberry Pi page if you can't find it) and check the resistance of it (it should only be a few ohms at most).

Re: Getting additional drivers built into the official image

It is my understanding that you will need to talk to the Raspbian group as they deal with that. I think generally it would be helpful to have a method by which NOOBS is able to inject additional packages when it builds the SD Card. It does support "flavours" but I think some additional work on makin...

Re: HC-SR04 Ultrasonic Sensor Arduino

The HC-SR04 sensor does need 5V for power but you can send the trigger signal using 3.3V. You will have to be careful with the Echo which will be 5V, but you can drop this to 3V using a few resistors. This works directly with RPi.

Re: Identifying the Pi over the network

An excellent tip from Raspi.TV is android app Fing. If you have wifi access to the same network it will find all the devices you have attached and make a guess at the manufacturer based on the MAC address.
