- Be careful what you name your company
- I would imagine that in 1976, the thought of their company getting into music two and a half decades later was at the forefront of their vision.
- Protect your boost converter
- No, it's a boost. Pin 3 is the drain of the internal MOSFET, pin 1 is GND, and pin 5 is feedback.
- Marketers talk funnier than ever
- I think a real definition of "courage" is recalling a phone that just started shipping for a battery fire problem. I may not like their phones, but I do have to give Samsung props for having the courage to recall the phones.
- Teardown: 12V AC adapters – The Horror
- I see that none of these have the earth ground connected to anything. Nice.
- Reduce relay coil current with a reset controller IC
- Bipolar transistors that have the bias resistors built-in. They are used more for digital switching rather than operation in the analog domain.
- Steve Jobs never would have done that at Apple
- Jobs' small tablet size argument is silly looking at it in context. The limits of placing elements on a touch screen were obviously good enough for a 3.5" screen iPhone that was introduced 3 years before the iPad.
- Was Tesla for real, or not?
- I love Newton's dig at Hooke!
- Glossing over lossy capacitors
- When the electrolyte freezes, the cap stops doing what it is supposed to do...
- Is China destroying the solar energy industry?
- Why should we expect a solar panel to last 25 years? Because it is a fixed installation and has a price that should be amortized over 25 years, not 2 or 3. Do you get rid of your house because it is 3 years old? Do we tear out a bridge and replace it every 5 years? Some things are expected to last decades. I would expect a solar installation to be on the list. A solar panel and inverter does not have moving parts nor is it moved around (getting banged and dropped). There should not be anything that breaks if it is designed right (except maybe an odd tree branch falling on a panel).
- What should NASA do next?
- Drop a rover on the ice located in the craters on Mercury's poles. See if there is anything interesting there.
