  • What are the best practical jokes ever engineered?
  • Here are a few quickies. 1- pop off and switch locations of the M and N key on your victims computer keyboard. 2- Take a screen capture of their windows desktop, save it as a BMP file and set it as their wallpaper. Then move half of their icons into the corner. The real icons will work, but the image of the icons won't. 3- put vaseline on the earpiece of your victims phone and call them. One longer one. We built hand held ESD guns. We had a manufacturing engineer that used to put on the wrist strap and pretend to fumble it as he passed it to other people, only to have it saved by the strap. He liked the way they panicked as it appeared it would fall to the floor because they didn't grasp it properly. We took a bad unit and rigged it to smash to pieces and then only loosely inserted the strap. Everyone was in on this but him, so when he tried to pull this again, the other person didn't even attempt to grab it and when it hit the end of the strap, the strap came loose, the gun fell to the floor and broke into a thousand pieces. We got him back but good.

  • I just use a non contact voltage tester. You can find them for under $10 http://www.all-spec.com/products/EX40130.html?gclid=CLXJ8qi6zcICFeXm7AodlGEAVA

  • Thank an engineer
  • I want to thank my high school physics teacher, Mr. Bradley Clough, for having an open mind. One day at the beginning of class he came in and caught me examining something he had on his desk. He took it out of my hand and said, "Curiosity killed the cat." I responded, "Maybe so, but look what it did for modern science." He promptly handed the item back to me and said class would start in a few minutes. I never forgot that, close to 40 years ago.

  • What happened to my scope?
  • Honey, I know I keep saying this scope is as crappy as a toaster oven, but I didn't mean for you to change it into one.

  • There’s a high probability you’re an engineer if ...
  • There's a good chance you are an engineer if you have four computers at home, a tablet and an x-box, four of which are wireless all tied to one router and no one else has the foggiest idea how they work. BTW- the glass is ALWAYS full. Remember- "The significant problems we face cannot be solved at the same level of thinking we were at when we created them." Albert Einstein

  • If you’re an engineer, thank your mom
  • This so reminds me of the movie Idiocracy. When stupid, uneducated puppets rise to positions of policy making authority then WATCH OUT!!! Ok, prosecute her, BUT, add all the members of the school board for encourageing her "bomb making" behaviour and teaching curriculum that is bomb related, her teacher for signing off on her project and every adult in the room for not seeing a potential problem and acting on it. If you make the claim absurd enough, maybe they will see that this is just a simple mistake and look into better safety mechanisms. Albert Einstein said, "If we knew what we were doing, it wouldn't be called RESEARCH."

  • All the great stories reminded me of the time I made a carbon arc furnace in grammer school and brought it in for show and tell. It consisted of the carbon centers of D batteries held by round curtain rods. They in turn were held by two pieces of upright wood and positioned so I could put a penny between them. My AC line that plugged into the wall had one wire going right to one rod and a cut section with two nuts wired to each section of the cut that I put into a small glass of salt water as a rheostat. I plugged it in, adjusted my "rheostat" and using insulated pliers put a penny between the battery centers. It melted a hole in the penny before blowing the fuse in the school. It had no shielding at all and was dangerous as hell and my fifth grade teacher just watched the whole thing. She didn't have a clue.

  • My mother let me take apart everything in the kitchen, but not wanting to anger her, I carefully detailed the disassembly so I could get it all back together again. Now, I can take almost anything apart and see right away what is wrong with it. Some of my chemistry "experiments" got out of hand and could easily have burned the house down if I hadn't acted quickly. This teaches you how to deal with emergencies, quickly. Unfortunately, this is all trial and error and doesn't happen to kids with helicopter moms. I would definitely double the insurance, though.
