  1. HI guys! hope u would be fine out there! WEll i have somewhat an idea about which i want to know what i have to do: If i have a webcam which connects to the pc thru USB and i want to control it wirelessly what i have to do?? I have some in my mind like: Suppose my WEbcam is present away from a distance from my PC. Now if i provide it 5VDC as POWER and GND, then i would be left with only control signals in the USB cable. I beleive that these control signals can be sent wirelessly from a PC to this webcam. What do u guys say?? I want to use TWS-434/RWS 434 for this purpose. It is a transmi
  2. haha nice Ante.. i think he must be looking for some reference book to read Be helpful please.
  3. Well! I agree with Yousuf Rafi! Digital Design by Morris Mano is also a good choice. But Floyd is easier to understand and its quite a practical book to follow.
  4. Hi Guys! Hope u would be fine out there! Well! im planning to make a robot. The drive mechanism that i have choosen for that robot is a Tri-Cyclic mechanism. That is two Big Wheels at the back, both of them will be connected with one single motor. SO there will be one motor driving two back wheels. Just like in a car. There will be a third wheel in the front portion of the robot that will be used for steering purposes. Now i want to ask you that what are the known issues and problems with this type of drive mechanism? WHat motor should i use for steering? Should it be Servo or a Steppe
  5. Well! Zeppelin! thats quite right! Sorry but the COST ISSUE just dint come to my mind.
  6. thanks MP for ur help! but what about that magazine paper method ?? If i use a magazine paper for this purpose, then can i use an Inkjet printer or even in this case a laser will work only? Someone in that Magazine paper topic has posted that the output of a photocopier works as well. SO if i dont have a laser printer with me , can i go with a photocopy of my image on a magazine paper? will it work then??
  7. call it in the Photoshop and see its image size in INCHES.
  8. Well! i think you can go with ORCAD CAPTURE CIS for drawing this. If the required IC symbols are not present in the libraries, there is an option where you can draw your own symbols with pins setup at different locations according to yoru own choice. I have used that software myself and im sure that this will help u in drawing almost the same schematic diagram. Not though 100% same :P take carez! Good BYe!
  9. Hi guys! well! im trying to make a PCB at home. THe first process that i came across is how to transfer my artowork onto the PCB. I have got a simple Copper plated board with me (no photo resist present) . Now i want to use the transparency method. I have got an HP DEskjet 3920 printer. I printed my artwork on a transparency's smooth side. THen place that printed side on my PCB and then put my iron on the top (rough) side of the transparency. But nothing happens. What might be the reason of this?? Is this is because, im printing my artwork from an INkjet printer rather than a Laser printer.
  10. Many many thanks audioguru! that simulation is very nice and informative. now please tell me something about my questions as well! thanks in advance! take carez! Good bYe!
  11. Hi audioguru! thanks for that precious simulation. But very sorry to say that i couldnt understand what u r trying to say with this. the circuit u have drawn is exactly correct. One mistake that i myself has made above is this that R1 = 4.7k not 5.7 k. so please make it correct in ur calculation. Please explain me what u r trying to say with this simulation diagram. I shall be thankful to u for giving me these answers which i require. Because i desperately need them. THanks a lot in advance! take carez! Good Bye! SB--
  12. Hi audioguru! Well! for the 1st question, i donot have a schematic.
  13. HI guys! well! i have got two question with me. Some forumlae i know and some i dont! please help me in solving it. here is the 1st question: There is a single stage class A amplifier which has Vcc =20V Vceq = 10V Icq = 600 mA RL = 16ohms Ip=300mA. We have to find: 1) DC Input Power 2) DC Power Loss in load resistor 3) AC power developed across load resistor 4) DC power delivered to the transistor 5) DC power wasted in transistor 6) OVerall efficiency okz, now i know how to find (1) and (6). What should i do for remaining. Following im wrtitng what i think about them. Please tell me i
  14. many thanks audioguru! and thanks for that legal information too. ;D
  15. HI guys! well! im trying to start a project. IN which i have to generate an audio frequency through 555 timer and this audio frequency is then to be supplied as an input to the electret microphone of a simple TWO WAY RADIO, so that it can be transmitted at certain frequency. On the recieving side, i want the signals coming out of the speaker of the TWO way radio, to be given to an IC. Now i have two questions: How to make this happened electrically i mean I want to input an audio frequency to the electret mic of a TWo Way Radio. How can i do this?? I want to take the output from the sig
  16. in which country do u live Mr. Alamin???
  17. many thanks to u NANOP! Thanks for ur concerns rigdoctor!
  18. Ante ! please arrange Elektor for September 2006! many thanks in advance!
  19. HI prateek! thanks for the explaination but there is something confusing in ur explaination. U said that field=electric field/distance what is the difference between Field and Electric Field?? and then how can u derive the constant R from the above stated three formulae?? please explain it again and this time in some more detail. thanks in advance! take carez!
  20. Thanks a lot Audioguru for ur help! but actually im asking you to tell me the Theory of Peak Inverse Voltage. That what basically is this. I donot want to use it anywhere so plz dont ask me what my supply voltage etc. Im just asking what is Peak Inverse Voltage itself?? How it affects the performance of a rectifier? It is said that a full wave rectifier has a Low PIV then a half-wave and that is the reason why a full wave is better than a half wave. I ask you why a low PIV is better than a high PIV??? In addition to this, please tell me that what is the advantage of using a Bridge Recti
  21. Hi guys! i want to ask you about the term PEAK INVERSE VOLTAGE of a rectifier what exactly it is?? and which one is good for us Low Peak Inverse Voltage? High Peak Inverse voltage?
  22. @rybitski HI rybitski thanks for the links! your idea looks pretty useful no doubt. please upload the detailed pictures so that i can fully understand what your idea is basicallly. @Theatronics Many thanks for that detailed pic theatronics. sorry but i still have some confusion in this picture, i want to know the plane of rotation of the bat is it rotating horizontally or vertically. And how the tube would be able to hold the ball, your notch idea is not cleared to me properly. Please please make it cleared! thanks in advance! Good Bye!
