  1. I think I saw someone fire walking the other weekend when we were there too! I was thinking then that people should probably have more extensive training in that area. Especially when there are big crowds of people watching. It's always terrible when people bring their family out to watch Dad fire walk and then . I hate when that happens.
  2. Well, I hope you were able to use that info. I felt like I was a little late in getting it to you. You have my phone number!
  3. Yes! But I would have still had to use my phone a friend option.
  4. Dang Rosie! I just now saw this. I wish you would have just PMed me with your question yesterday. I could have gotten you a more timely answer. Hope it's not too late. So, what this is is an op-amp based voltage amplifier. An op-amp (drawn as a triangle with a + and - sign on one side) connected in negative feedback (with its output connected back around to its negative input) will tend to equalize the two inputs. Meaning that we can consider the two input values (i.e. the voltage nodes connected to the + and - terminals of the op-amp) to be equal. From there, the problem gets more straightforward, since it is generally just solving the voltage divider equation. From the voltage divider equation, we know that V- = Vo * R1/(R2+R1), or that Vo = V- * (R2+R1)/R1. (I can go into more detail on that point if it's needed.) The input voltage is going to be Vos+Vp*sin(omega t), if I'm reading the schematic correctly. The amplifier will then amplify that by a factor of (R2+R1)/R1. This will give you the output voltage. The maximum output voltage will therefore be ((R2+R1)/R1)*(Vos+Vp), and the minimum will be ((R2+R1)/R1)*(Vos-Vp). Note that, because the supply voltage on the op-amp is +/- 10V, that will limit the output, so if either of the voltages is outside of that range, they'll be clipped. I think that's all that the question is asking. I'm not sure why the Slew rate is given, if the frequency of the input wave is not. I also think you'll need to know the value of Vp to find the maximum output swing. Note: I'm an Electrical Engineer, and and one whose been spending too much time around other EEs as of late. All the words above make sense to me. They may not make sense to everybody. **OK, just so you know, I'm not the whiz who solved your problem. However I do surround myself with extremely knowledgeable people. That one came from a Senior at Olin College of Engineering.
  5. Good luck! My fingers are crossed for ya!
  6. I was in a Lowes Hardware store the other day, walking down the plumbing isle, and some woman approached me and asked if I was a skydiver. It took me by surprise because I wasn't wearing a skydiving shirt or anything. How in the heck did she know I was a skydiver? Then I remembered I'd stuck a closing pin on my gold chain. Duh! Turned out that she and her husband were long time skydivers as John and I are. We sat and chatted with them for about 45 minutes about the good old days.
  7. Happy Birthday! How was the cake?
  8. Congratulations on the new home! Check out Craigs list for the fridge! Don't let home ownership get in the way of skydiving or you'll never get back out there. Owning a home means there is never and end to the list of chores to do. It will always be there. Make sure you still have fun every now and then.
  9. Fixed it for ya. Hey, cars are cheap at ONT. I just picked up a midsize for $15 a day. Why the bargains? They knew you were coming. Me too! I'm coming!
  10. That isn't how you asked me out.
  11. I personally hate chocolate milk for that very reason. Breast milk is much thinner though.
  12. What woman would want to be milked like a cow every couple hours? They would have no life?! That is the reason why people have gotten used to drinking cow secretions rather than mother's milk. It's probably taken women centuries to make you think that sucking on a cows tit is better than sucking on theirs. That is why you all go "Ewe!" when we say "breast milk". That's what we want! We want a life beyond milking. But just so you know... If you like chocolate milk, that's about what breast milk tastes like. Sticky and sweet. Why do you think all those babies slurp it down?
  13. You could also put the Whipped cream frosting on it and then sprinkle those little colored candy balls cake sprinkles. That would be really festive and fun. Or you could slice up some fresh strawberries and put those on top, kind of a strawberries and whipped cream thing. Yummy! There is lots of things you could do with the whipped cream!
  14. Also here is another idea: Whipped Cream Icing 1 tsp Unflavored gelatin 4 tsp Cold water 1 cup Whipping cream 1/4 cup powdered sugar 1/2 tsp. Clear vanilla extract Combine gelatin and cold water in small sauce pan. Let stand until thick. Place over low heat stirring constantly until gelatin dissolves (about 3 minutes). Remove from heat and cool slightly. Whip cream, sugar and vanilla until slightly thickened. While beating slowly, gradually add gelatin to whipped cream mixture. Whip at high speed until stiff. Yield: 2 cups.
  15. Angel food cake is very light and fluffy. If you do put a frosting on it you'll need to water it down a bit and kind of drizzle it on. If you make your own frosting you could just add a little extra milk to the mixture to make it more runny. I don't think it would work to well to spread thick frosting on it like a normal cake because it would probably tear apart. When you bake it, make sure you use a cake pan that is made for an angel food cake. They usually have little "feet" on the top of the pan so after you take it out of the oven you can tip it upside down and rest it on the "feet" while it cools. You can't grease the cake pan either. So you may have to use a knife to slide around the edges of the pan to get the cake out.
  16. Sorry sweetie but I was just agreeing with the previous poster about texting. We'll just let you get back to your texting at the table.
  17. Wow! That's pretty trick! I've saved that in my fav places. So when are you going to visit up here again. I know of a really healthy place to eat when you get back this way. Except just take a small piece of pie at the end of the meal and everything will be fine. SuperSucker!
  18. See this is exactly why I had texting removed totally from our phone service. The first time I saw my daughter when she was 16 texting with one hand and driving with the other is the day I put an end to it all. Kids think they are so smart and they can do anything and nothing will happen to them or the poor people they hit. I even see adults driving and texting so it's not just a kid thing. Although I totally am glad that texting worked for you in your work situation with the Red Cross, I don't see the uses for it in any other situation. It's just not necessary and it's a nuisance and irritating and in some situations very dangerous.
  19. Stupid women! They don't know what they're missing out on!
  20. I don't understand your question. Doesn't married mean you get extra humps just because you can?
