    Hopefully no law agency used the polygraph, considering they are about as accurate as fingerprints and DNA evidence, or as accurate as hearsay

    JFETs with pliot lights? Dave, what are you doing? Just laughed my tea out all over the table. Now gotta wipe it.🤣

    Potted capacitor – Does it taste as good as potted tripe?
    Sagan's mini-Australian accent is cute…

    Looks like the Chinese University Press doesn't have ligature print blocks.

    You don't think of books as being something that people counterfeit. You hear about dodgy clothes or handbags etc but when you think about it, some books are quite expensive so if you make a cheap copy and your not having to pay any royalties then it's probably quite a lucrative business.

    yes it is the chip, tight bastards skimped on a heatsink, the sigma chips need one.
    are lie detectors admissible in oz?, in the uk justice system polygraphs are considered pseudo science and not reliable.
    if customs had seen that honey they would have destroyed it, there are very strict rules on stuff like that.

    Sagan is one lucky boy, imagine growing up with all that equipment and stuff around… Amazing!

    That lad clearly does no have enough limitation or boundary's – how dare he think he can mess around with adults s property. What's the betting mum or dad keeps asking him what he wants to eat when they go to the supermarket.

    Does that vibrator (proper name for mechanical chopper) have a B7G and a B9A valve bases?? That's soooo strange. I've got a tiny CVT (constant voltage transformer) on a B7G base which is bizzare but this might be even more wierd. I guess it's so you don't accidentally reverse it.

    The covers side by side are like a game of "Spot the differences".

    Its a photocopied boot leg copy made for college students so they can afford the thing. Does that mean the original copy is priced way too high?
    Most students are strapped for money as it is, books being the second most costly thing per semester. By buying a cheap knock off REQUIRED book for a class, that student can save money. Yes, the book may not be perfect, as long as content is correct. Why did they change the spelling though? Dummys.
    Just photocopying an original wasnt enough, they had to retype the opening pages, then misspell them.
    lots of scams going on out there.
    The Chinese are good at copying stuff, but to muff it up in the process is not a compliment. Knuckle heads.

    Your boy is amazing. I so enjoyed this video. Brings back happy memories of when my son was this fun age. 🙂
