Re: Ciseco Wireless Inventors Kit - OS image replacement

I keep hoping the same myself, it's a huge shame these things can't be purchased any more. I think they could have done more with the XRF & SRF modules, I hope the designs and source code for the firmwares surfaces sometime.

I did find this which is very useful:

Re: New web browser - it's here!

Is there any way of telling that this modified version of the browser is installed given that epiphany-browser is still a standard Debian package name? I've installed epiphany-browser and by looking at that youtube html5 page I guess it has worked OK. But when I compare the apt-cache show page for t...

Re: HDMI to analog DVI/VGA conversion (+audio?)

I've got a HDMI-VGA adaptor which I bought from Amazon a few months ago, it looks the same as the Farnell ones. It works OK with a bit of tinkering in the config.txt file but the image quality and available resolutions aren't anywhere near as good as when using HDMI/DVI. The adaptors are only about ...

I just found this by googling the warning message you posted:

It was the 2nd result down :)

Changing to a different OS just because of this is a bit drastic!

Re: Slim down Raspbian?

Time. It's a lot faster to write an image and then strip the packages than downloading individual packages and installing them via the installer, at least for me anyway.

Re: Slim down Raspbian?

what's wrong with just using the raspbian installer on the raspbian website to build your own stripped down image? This is what I've done, it just has ssh running and nothing else (aside from the base OS of course). That's way easier than installing the full raspbian official image and then trying t...

Re: Moving /var to a NAS

In my opinion you'd be better off moving them to a USB stick if you are worried about your SD card. Or just making sure applications are set to minimise logging or make syslog send logs to an external syslog server over the network. Or make /var/log and /tmp into tmpfs files in memory (although this...

Re: Seeking 868MHz Transciever for Pi (Farnell or RS)

The ciseco xrf module either wired to the uart or using their sliceofpi board works well. They support several frequencies but default to 868MHz. They sell them directly and through eBay. Don't think farnell or rs do them though.

Usually good from a security point of view too, bugs in your web interface code have less chance of breaking your controller program. If both applications always sit on ...

Re: CPC Product Recall: Power supply

Yes, I've already had mine swapped out by farnell. The issue is the fixings between the casings halves can fail meaning the back case comes off when you try to unplug it. This leaves the mains wiring exposed and could be quite dangerous so its definitely worth getting it replaced. Farnell refunded m...

Re: Does leaving your Pi on all the time do anything???

As above, it's arguably better to leave it on all the time than keep turning it on and off. That's why NASA don't test backup systems from time to time in space probes etc... it's more likely to fail if they keep booting it up than if it's just left off. Remember in the news a few years ago about th...

Re: hot USB port

the USB ports on mine are warm from heat radiating from the USB/Ethernet chip which itself is very hot (which is normal).

When you say the USB port is hot, how hot exactly? It shouldn't be too hot to touch.
