  • Even if this might sound crazy to some, it doesn’t sure me at all. Industries are not upgrading systems just for fun. It’s only done when it is absolutely necessary.

    I’ve worked with systems running in windows 95. On laptops so old they didn’t have USB. The only way to transfer new files to it was to use serial link (we didn’t have floppy drives). What did that ancient computer do? Communicate with subsea control systems for oil wells.





  • The problem isn’t the LED itself. The problem is engineers that read the datasheets where it shows which forward current they need. What they forget to think about is that the recommended forward current is for max brightness, so they slap whichever resistor they need, and never give it another thought.

    Whenever I design a LED circuit that is only used as an indicator, I always make it 10% or less than recommended, because I do not need to burn away my retina when I test the boards.
