As the LEDs were portable, I would bring an LED with me to other Faire's, it has always been received well and many times people would ask was it for sale.

This can be equally true whether you’re using a magnetic finder and it’s reliance on “feel,” or an electronic unit that can give fuzzy readings (especially when the batteries are […]
Do you have any Star Wars fans on your list? Given the reach and output of its new corporate masters these days, it might be easier to ask if there’s anyone out there who isn’t a Star Wars fan. So let’s narrow it down further: Do you know a Star Wars fan who likes to […]
There’s much ado about coffee brewing methods these days, but most of us – at least on the busy weekdays – just want our morning joe to be consistent, easy, and most of all, fast. If that sounds like anyone on your Christmas list, they’re going to get a lot of mileage out of the […]
