  1. How uneven the difficulty on my course is. The maths has been nightmarish with one stupidly big equation and other things on it. Whereas the electrical stuff so far is too easy. None of this math is spefically engineering related either. At this rate because of how screwing up one assignment in a unit stops you getting any of the higher grades on that unit I’ll be lucky if I come out with a merit overall. The equation was so complex that when putting all the numbers in for each value and raising them to the right power (because some units had different metric prefixes) my calculator ran out of memory and I couldn’t finish entering the values needed.
  2. I have made the rather worrying discovery that it’s not just my maths knowledge that has faded since my last course but also my knowledge on thevermin’s and Norton’s theorem, I can only manage using them on very basic circuits right now.
  3. Started to decay all over and give off alpha radiation, parts have turned into Th-231
  4. At least you are not doing dimensional analysis stuff that wants you show that Cd (Cd being discharge coefficient) is dimensionless. And to rearrange a formula I find too hard to rearrange due to its size. (I can only manage small 3-4 term ones) Stuff with mass flow rate and volume flow rate caught a few of my class out at first, me included.
  5. How I'm supposed to use dimensional analysis to do this deriving equation stuff. First question on this part of the assignment wants this done with the pendulum formula. The second wants it with deriving units for G in newton's universal gravitation formula somehow. And the third question wants me to derive Reynolds number from some quantities that make the formula for it.
  6. Questions on dimensional analysis. Especially this one that wants me to show one constant in this equation is dimensionaless. And make one of the terms the subject of the equation for the second part. For the record I've not even covered this related thing to dimensional analysis called the Buckingham pi theorem. I don't think I'll need to know that yet though.
  7. I think I have taken on more than I can manage with this HE engineering course. I was vastly outpaced on a lesson designed to prove everyone's general maths skills because I had largely forgotten how to transpose equations and do fractions stuff mentally.
  8. I've mentioned a lot of math stuff subconsciously as well at times I've have forgotten. It is most likely you processing information in your sleep and getting confused over the result. That or you are feeling nervous about where this internship will go.
  9. Having finished my engineering course I'm slightly nervous about the difficulty of the HNC I'm taking next.
  10. I think most of the things in the images so far have the word steampunk in just to try and draw more search results. I can't believe sticking random circuit boards and a speaker on a bit of cloth would make it worth $10 let alone $185. $40 for a valve stuck to a jar lid is absurd, assuming it hasn't burnt out you can likely sell it for more than that to people who restore old TVs, radios and audio things.
  11. Had a accident with sheep shears.
  12. If I did go with one as part of a new build I'd probably have a smallish SSD as a boot drive and just stick everying else on a RAID 1 setup. I'd figure a lot of SSD failures are because it's still rather hard to make the special floating gate MOSFETs used to form the memory cells in the things. Wear levelling is meant to make the cells last longer.
  13. And this is why I'm not touching SSDs for some time, even though a lot of people use them more nowadays.
  14. Out come a lot of actual bugs like bedbugs and stinkbugs. In goes a 486 based PC from 1992
  15. Boops many times
