      No need to be ashamed by item 1, it takes all kinds to make the world go round, and to each his (or her) own.

    • Hey Dave.

      I was thinking, for the broken LCD window, couldn’t you remove most of the broken glass, and then pour some 2-part clear epoxy on top? Or would shrinkage, heat dissipation (while the mix cures), or whatever, cause problems?

      As for CC dummy loads, are those a bit like DMM’s, where you can’t really have too many of them?


    • at 3:00 i was SO expecting it to be an accompanying dildo :p

    • Take the dress appart ;)))
      I vote for a teardown (on an appropriate model :)

    • I have the exact same digital calipers which I bought from a computer swap meet for 20 bucks. It came in a nice plastic case so I am surprised that yours didn’t. Believe it or not these are very high quality compared to a lot of others. The residual offset can be reset by pressing the zero button. They are great for measuring up stuff when you are laying out pcbs’s.

      • Same caliper here, nice plastic case included.
        If that port allows reading their measured data, these cheap calipers could be hacked into linear encoders for CNC machines or robotics.

      • Same here, but 9 bulks from ebay

    • Re. the C C dummy load.
      For longer use when the power-dissipation on the heat-sink gets to high. Connect a power-resistor in series with the load. If you calculate the value with regards to the current and the voltage you can make most of the power dissipate in the resistor. A power-resistor can stand much higher temperatures than a mosfet.
      Just don´t burn yourself on it!
      I have used this in a 12V 100A CC load for a long time. Works great!

      Keep it up Dave!


    • Does anyone know where the nice PCB mounted BNC connector can be obtained from / what it’s part number is?

      Thanks all,

    • Is it just me ?
      the video ends in the middle of a sentence at 6:57 .
