Recently, one of my friend told me that he has a fancy dress competition sort of thing in his office. We went for shopping with a hope of finding a Christmas themed sweater with LEDs, with a hope of winning the prize. I remember seeing them in Primark in the UK, but now I moved to Ireland. In Ireland, Primark is labelled as Penneys, where we didn’t find any such fancy dress. So we bought a sweater, nonetheless with Christmas Trea on it. We decided to decorate that with LEDs. I have some LEDs lying around, which I bought from Dealz (which is Poundland in the UK). Somehow, I sewed the LEDS, but its not a neat job. But I managed to hide the ugly sewing job with another sewing job (see the pics). But the end product is very good.
My friend won the fancy dress prize, not because he was the only one to wear a sweater with LEDs, but others have just bought their dresses with LEDs already built into them. Moreover, their LEDs were quite low power ones, which can’t be seen in dark, where as ours is quite powerful. Why not, we are powering with 4AA batteries versus their coin batteries.
