  1. "Fundamentals of Electric Circuits" by Alexander and Sadiku has stuff about amplifiers and filters. Mostly small scale stuff, but the same theory applies to larger stuff. But thats a very small portion of the book so idk if its really worth it if thats all you want. Most of the book is about circuit analysis. Some books that I haven't read but will have to read eventually for various classes are "Power System Analysis and Design" which would most likely have the high voltage/transformer/coil stuff your looking for. Also "Power Electronics: Converters, Applications, and Design". Keep in mind these are college books meant to be used with a professor, so they can be hard to self-teach with
  2. Well the only non-college book i've read is "Basic Electronics", its a radioshack book that they probably don't sell anymore but could be found on amazon. Starts with basics and works up, nothing too fancy if i remember correctly. As far as college books go, I semi-enjoyed the book "Introduction to Computing Systems: from bits and gates to C and beyond", but partly because the writer was my teacher. It's a nice intro to low-level computer systems. For logic the only book I own is "Fundamentals of Digital Logic Design" by roth, but I haven't read much of it. What I have read has been pretty easy to understand. That book is meant for a self-taught college course, so I imagine it would be the easiest to understand without help.
  3. Very nice! I'm taking a class on embedded systems right now and we were given (paid for with non-optional lab fees) Motorola 9s12 prototyping boards. While nothing we do in the class is going to be very complicated (the hardest being an led "traffic light"), I have my own plans for the micro-controller. I'll start off small but would like to learn to output images in a format I can view on my tv, and write some little games for it.
  4. I had it for a while and got rid of it, The version that was leaked was not the full version. Most of the useful function were not included.
  5. I know lol, you told me to PM you... nvmd, oh well lol
  6. Lol why did you quote my pm? and @ quertyman, thanks already bought my ticket though :-)
  7. Hey guys I was wondering if anyone knew about any decent conventions that come through Austin, tx. I couldn't find anywhere else to post this so sorry if it's in the wrong place. The only one i have heard about is the Maker Faire which i've already bought my weekend pass. Any ideas?
  8. I understand that capacitors work different than batterys, that they work in quick bursts. I am building a solar engine to use on a "beambot", i can charge the capacitors with a battery but i havent been able to get the capacitors to charge with the solar panel. the design i was working off of is here link
  9. I am not the most experienced with electronics and I am just now really getting into any kind of circuits. I had another post about transistors for some robots i am working on and now i need some more help. I can't seem to get my solar panel to charge a capacitor. The solar panel is 3v 25mA. The capacitors I am trying to charge is a 1000uF 6.3 volt electrolytic. Is the difference in voltage the problem? And help much appreciated
  10. Cool thanks guys, I'm not going to be ordering from radioshack anymore anyways, i just wanted to be sure that these transistors would work in place of the one that i needed. Thanks again.
  11. Like i said i was making solarbug or beambot, you can see the design at the bottom of this page. Some of the numbers on the transistors include mps 6534, mps a55, and pn4258
  12. Yea i made the mistake of using radioshack because it was quicker than ordering but im returning some things and i will never use them again unless i'm forced to do so. The package says "2n3906" and its a package of fifteen. They should all be 2n3906... Will the other transistors work the same way? it doesn't make sense that they would put an assortment into a box that was just supposed to be the 3906..
  13. I wasn't sure where to put this but this seems like the most appropriate place. I am working on building a solarbug, aka beambot, and i purchased a pack of 15 transistors at radioshack, they are 2n3906 general purpose transistors. Well when i got home and opened the package, the sides of the transistors did not have "2n3906" on them. Only one in the entire box had the correct number. Is this a mistake in packaging or is that normal? This is my first time to purchase transistors and figured that the part number should be written on the side of each part. I also purchased 2n3904 transistors individually and they each had the number written on the side... and help?
  14. Well its actually taught me alot so far, idk why it shows those errors in the examples, maybe they correct it later because it doesnt make much of a difference right now.
  15. It didnt TELL me to put it there, its just there in every example they use. That may be because they havent covered that yet, or it may be a crappy book. Its SAMS teach yourself c++.
