Each week I will grab a random electronic component from the vault and build a circuit - this week I look at way too many LED lights - why, why??

When you plugged in the USB sound to light device, I was yelling at the screen and laughing my head off. It's the funniest thing I've seen for ages.. LOL.

@3:02 - weird little unit. You can add DS18B20 as well to have 3-in-one (board have place for it and dedicated output pin). For use with non-rechargable battery, you need to break charging circuit - by removing couple of elements as far as I remember. Clock by my experience is BAD, runs away very fast. maybe I've got bad crystal.

Aye, shipping is getting expensive, 0.99 or free shipping is getting to be a thing of the past. Like you, I've made separate orders to get multiples of an item. Lately I've noticed when ordering multiple items, if the shipping bumps up too much I just reduce the the number of items to get the shipping down, guess I really didn't need that many anyway. Wonder how many sales they're loosing due to the shipping cost?
