HI Aled,

Yes, the Kisi locks have been removed from the space. Apologies for the inconvenience.

Can you arrange for Tino to hold a spare? I know that is no good in the evening.

Yes, Sorry, the kisi system has gone now for reasons discussed in recent
meetings.

We are working on alternative arrangements, including building our own
equivalent if necessary. Anyone with experience of door systems should
let us know :)

We apologise for any inconvenience in the mean time.

That doesnt say anything about how much throughput it has, or how noisy
it is likely to be.

The K40 discussion group on google-plus seem to use large aquarium
pumps, as they have a good flow rate and tend to be muffled/quieter
designs.

A simple enough project in principle, there are lots of grabber/claw
designs on thingiverse that you can download and 3D print or laser cut. 

They tend to use a single servo as the motor, you then need a very small
amount of computer power to run the servo, one of the small Arduino
family boards will do the job, even just an 8-pin ATtiny85 chip will be
enough.

One IO pin to the servo, one or two for buttons, and the battery.  You
can either have two buttons: one open, one close.  or have a single
button that whilst held makes it close slowly, and when let go makes it
open slowly.

how strong the grip is will depend on a mix of the design of the claw,
and what size/strength of servo motor is used.
 
hope that helps

You could even do this without a micro controller, a simple circuit using a 555 timer chip would work to control the relay and cost only a few pennies.

Here is an example of a circuit to control a relay-

http://www.555-timer-circuits.com/servo-tester.html

You could then use a rotary knob to control the position of the claw, or modify the circuit for open and closed positions with 2 buttons and a capacitor.

Hi All,
What do you use for filtering your home internet for children?

There is BT Parental Controls if you're using infinity broadband but I've
also seen examples using Raspberry Pi as a proxy running Squid/Squidguard.

Can anyone suggest a solution that's configurable and manageable remotely
please? Thanks.

Happy Easter all,

You've not had a lot of answers, but can I suggest investigating the 
problem a bit further.
What does BT filter? Researching it shows that it i domain based. That 
at least is better than local councils who in the web filtering for 
librariesand their email systems use a very stupid word based system.

However, BT's filter is made by another company and therein may lie a 
problem. A lot of these things are driven by American bigots who want 
their children protected from all sorts of harmless things, Evolution is 
one of those so just about any decent and harmless biology site is going 
to be off limits. If you have any doubts about this check any American 
forum. I am currently receiving postings from young earth creationists, 
racists, homophobes and genocide deniers.

Those of you who have been members of the local Linux User Group will 
remember Rhys Sage AKA "Secret Agent Sage" who went off to America and 
managed to

Very insightful Neil, thanks for the response.

I'm less keen on the BT Parental Controls for the exact reasons you
highlight, and would prefer something more open source and configurable in
terms of what is filtered out if possible.

I do have a couple of Raspberry Pi computers I could use for this so a
solution that runs on RPi would be nice but not a must have.

Thanks again,

Richard

I actually looked into this in some detail about 6 months ago.

I started off with the idea of using my currently unused Pi for this purpose.

My initial considerations was for a transparent proxy that would route traffic by default rather
than having to change IP settings on each machine. However, that led me to the next question of
setting the Pi as each machine's gateway rather than the router, in that if I can set the proxy one
way then the kids could set it to the router and 'hide' their activity. It may seem overly paranoid
but then I know what I would have done in the same situation!

To avoid, the whole IP settings config question, I then considered getting my router to mirror
packets to the Pi as they were being routed. That way I could log them by default. Unfortunately,
this functionality was not available on my router (billion 7800N) as its iptables implementation
seemed to be too old. So, then came to the idea of a new router running custom firemware.
Unfortunately, never got much further than that.

In the end, I kinda lost heart in the whole idea since if it was this difficult to make it foolproof
then I really would not be trusting my kids. Maybe, I would try things without and keep an active
eye on their internet use - again not foolproof either but can still look into at later date.

Apologies, this is not the solution you are looking for but may give you some further points to
consider.

If your router has good enough firewalling, even an old iptables will
probably do, it can do transparent-proxy-to-remote where any outgoing
http requests get silently redirected to a seperate machine running the
filter/proxy.

If your router is fairly dumb then you can run a linux box (eg RPi) in
bridging mode, and put it between the router and lan, or between the
router and the wan/modem. it can then filter/proxy any traffic you like,
and simply bridge the rest through.

What you use to do the filtering i leave to others to comment on.

Many thanks Justin, this is sounding more like what I 'think' I want.

I will read up on 'transparent proxy' and 'iptables' to improve my
knowledge.

Thanks again to the list - great advice and guidance as always.
