Re: DS18B20 and 30-Jan firmware

Just to confirm, that everything is good for me on the latest update - it works just fine! I just added the one line to my config.txt file (I don't have access to the machine right now, so can't confirm exactly the syntax, but it was exactly as explained in the README file), rebooted, and all is goo...

Re: DS18B20 and 30-Jan firmware

Excellent, thank you! For some reason, if I search for w1-gpio or w1-therm, that topic doesn't get found, so I didn't see it. But that's great information, thanks :)

DS18B20 and 30-Jan firmware

Hi all, Sorry if this is a repost - I've done a quick search, and can't find anything, so I'll risk the (deserved) wrath of the forum and post a new topic. Please feel free to tell me how to use search if this has already been done to death... I've been using a pair of DS18B20 sensors for ages now, ...

Re: Dead NSLU2 prompts upgrade to Raspberry Pi

I have a similarly dead NSLU2 in a box in the loft, which I used for serving a Soundbridge too... I now use minidlna on my pi [1], still serving the Soundbridge, with the library stored on an external disk, so yes, it's entirely possible. In my case the disk is EXT4 - but reading EXT2 or 3 will be n...

Re: Noise generation for electric vehicle

Many years ago on a C64, one of the ways to make a kind of engine noise was just to turn the SID chip on then off again in succession. Each switch made a low-ish frequency click from the speaker - so you just reduced the delay between the clicks as you wanted to make a faster engine noise. Sounded p...

Note to self: ensure that the monitor you're plugged into via HDMI has audio capabilities before complaining about lack of function in audio software :oops:

Yup - was using a monitor without any speakers. That would explain why I wasn't getting any sound.

Re: No access to internet via wireless

Hi,

Wireless ethernet isn't supported on RISC OS currently. You can possibly get around this by using another access point in client mode connected to the ethernet port on the pi, but that's really a bit of a bodge.
