Do your eyes glaze over when looking at a long list of annual health insurance enrollment options – or maybe while you’re trying to calculate how much you owe the IRS? You might be wondering the same thing we are: Where’s the guidebook for all of this grown-up stuff? Whether opening a bank account, refinancing student loans, or purchasing car insurance (...um, can we just roll the dice without it?), we’re just as confused as you are. Enter: “Grown-Up Stuff: How to Adult” a podcast dedicated ...

In our WLED design, we want to have two (or maybe three?) DC power inputs, where each can be up to 24V, and supply up to 5A of current into the LED strands. In our typical designs, like the Metro or Feather series, we don't really go above 1A or 2A and 20V. Let's take a look at what is available: we want to have the lowest possible forward drop because, at 5V, we want to have no less than 4.5V going into the LEDs, but we also want to minimize the reverse current which can start to get non-trivial at these capacities. Also, should we go with an 'ideal' diode chip or with a Schottky diode?
