Re: Rasberry Pi as in car pc

This is definitely on my to-do-with-Raspi list. Not the initial Raspi though; partly because I have higher priority projects for it, and partly because I already have a PC-based car computer that can serve me until I can got hold of more Raspis ;) . Here is a short description of my current system, ...

Re: Camera module! (And a picture of JamesH)

Very interesting stuff! A few points: 1. About IR filters, do modern phone camera modules invariably incorporate an IR blocking filter? Traditionally this wasn't so; hence the old trick of checking if your TV remote is working by looking at the business end of it through a phone camera. Of course, t...

Re: What is connected to the 5V rail on the Raspi?

<t>Thanks for the information.<br/> <br/> Well, I didn't expect the HDMI designers had added the 5V rail just because they had an extra pin available , but I couldn't think what it was for (my best guess was that it was to power active signal converters, a possibility that might still come in useful...

Re: Powering the Pi via the expansion Port?

<t>As I understand it, yes, but you should provide your own protection device (fuse/polyswitch/etc.), as you are bypassing the Raspi polyswitch.<br/> <br/> A quick google didn't turn up any datasheet for LM1302. I assume it is a buck/boost switchmode regulator? Not sure why you would need a shutdown...

What I've found out already:<br/> <br/> USB connectors<br/> <br/> HDMI connector (probably)<br/> <br/> NCP1117 LDO regulator,...

Re: Introduce yourself!

<t>Having spent the last couple of hours crafting a supposedly-droll introduction I'm feeling just-a-bit-miffed at being informed that I failed elementary addition (since when does 8+7 *not* equal 15; I mean we are talking about decimal notation, right?), so this is the short version:<br/> <br/> Cut...
