Sponsored amble - and chucking out time

[ffutures]

I seem to have volunteered for a sponsored walk/crawl/whatever on the 25th, covering the massive distance of a mile, to raise money for my school's new labs - hey, we're a registered charity, it's not like I'm asking for the money for me...

Don't have the details yet, but at some point I will probably be asking for money. I suspect that this will be done somewhat chaotically, but hopefully it'll be possible to take money via PayPal - if not it may be a bit difficult to organise, we'll just have to see.


In other news, I need to discard various bits of lab gear etc. that are surplus to requirements. First on the list will probably be a couple of fairly large and extremely heavy chart recorders, I think one measures voltage and the other temperature, both possibly useful for components or retro-tech stuff. We can't sell them since they don't have electrical safety approval. Anyone interested? Needless to say, they'll have to be collected from Central London.


Finally, does anyone have a spare regulated 12V 1A power supply? The power pack for our best balance has died and the manufacturers want silly money for a replacement - I know because it has been running on the power pack from one of my old scanners for the last three years, and that's what's finally died.

If it's DC , maplin sell PSUs . Most of them these days are switched mode rather than a simple stepdowns +rectifier.

If your really worried about the regulation put a 7812 on PCB, they are rating at 1A.

So far three Maplins I've tried are out of stock, except for the next size up which is 18 quid.
