I’m building an Air Quality sensor. As you do. I need a variety of different nuts, bolts and washers to hold bits of it together. Normally this would be a pain, as I’d have to buy twenty of something I only need four of.
But now B&Q (the big diy warehouse in Hull) have a “pick’n’mix” display for things like this. It’s like it used to be with the sweets at Woolworths. A full bag like the one above is around two pounds fifty, which is fantastic for making things.
