I still like the idea of a light beam....interrupted when the box gets full

Capacitative sensor should be even better. No risk of lenses getting covered in dust.

'twould appear you're not alone with that idea as a quick google threw up this option. I did like the one suggestion which was to have a vane that was spun by the airflow and generated a voltage. As the chips reached it, it stopped turning etc etc.

I'd completely forgotten about my second foray into cyclones





It was the not knowing when it was full that made me abandon it, as I recall.

This my home made cyclone.

I have 2 dust bins, mounted on casters so I can swap to an empty one quickly.
The blower is mounter on the top, just out of shot, linked to the filters with a bit of 6" flexible hose.

Interesting that the metal dustbin resists the vacuum pressure - my early experiments resulted in a squashed flat bin, but it was not ribbed like yours.

we got one of these IR beam alarms from maplin. bought it to know if the cat jumped up on the kitchen worktop so it could be discouraged from the idea. The cat stopped jumping up when the alarm was there but footprints just showed it had learned when to stay off.

Guess it could monitor wood chippings as well as cats

I suggest that you didn't use quite enough voltage in the electrified worktop defences, or quite enough disguise, Robert. If I had gone to the trouble of setting that up, no cat would ever have leapt up there a second time. I guess the trick is have the right voltage to send the cat flying across the room without actually setting it on fire.

I had a similar problem with a dog that liked to empty the rubbish bin when no-one was looking. Mousetraps worked wonders, but I did catch SWMBO once or twice... :lol: :lol:

RogerS - I can see that this thread has moved on somewhat , but I wanted to mention that I spoke to Nikki at RB , in Andover , yesterday , incredibly helpful , I can pick up a Torit-equivalent filter from them myself for about £61 so its in the plan . If I can make room I might move the extractor back into my workshop/garage , scrap the shed , and save heat in the winter too .
