  • Lucky you. My dad died from cancer when I was 14. That was rough.

    Recently my mom died at 70 years old. The last time I saw my mom alive was at her sister funeral a month before. Three months later, her last remaining sister died. Same year my brother in law also died. 2022 was so far the worst year of my life. Covid was not the reason for any of the deaths.

    But hey, no matter how bad things might be, they can always get worse.











  • 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.
