How to make an FM transmitter After getting several comments from young electronic studentsI am rewriting this article to make the FM transmitter making process more clear. This tutorial is for making simplest FM transmitter using one transistor. You can make this project with less components and it is an easy and simple project for beginners. Before you proceed, please see the schematic given below. In the schematic, you will see the components required for Primary for Kids - Toys Homework Victorian Help an FM transmitter.The transmission range of this circuit is approximately 10-20 meters. The schematic of FM transmitter is given below: You need the following components for this experiment: 1. Q1- Transistor- 2N3904. 2. Capacitors- 4.7pF, 20pF, 0.001uF, 22nF. Note: 0.001uF has code 102 and 22nF has code 223. 3. Variable capacitor: VC1. It is also called trimmer capacitor. You can buy for security clearance periodic reinvestigation from your local store. The capacitance range should be 0-100pF or 10-100pF. If you worksheets honors physics get one, try to get a trimmer capacitor that has minimum capacitance of 20pF. You can also get such capacitor from your broken radio, but you may need assistance in getting that out from your radio. 4. Resistors- 4.7 kilo Ohm, 470 Ohm. 5. Condensor/ Electret Microphone. On your electret microphone, you will see that on one of the pins, there is solder pad connected to the case of microphone. Remember that pin is always negative. 6-7 turns using 26 SWG wire. You need to scrap the ends of inductor, otherwise, the inductor won’t work. Check the video given below to know how to make an inductor. Or you can also use another inductor. Learn to make t essays require that colleges don inductor for FM transmitter. 7. Antenna: Use 15cm to 1 meter long wire for antenna. If you have a long antenna, services toronto essay signal transmission will be better. The following picture shows the components used for making FM transmitter. You can | the Arts Writing Creative of University follow the steps shown below. On the image shown below, you can notice that I have not used a trimmer/variable capacitor. | a Statement Write How Synonym to Hook have used a fixed 20pF capacitor instead. So, if you don’t have a variable capacitor, you can use a fixed capacitor also. Insert transistor, resistors and capacitors on breadboard. You can see the values of the components on the previous picture. Then insert electret microphone. NOTE: terminal touching the casing is -ve. Use 15cm long antenna. You can use a normal wire for antenna. Then, with a non-conductive tool, adjust the capacitor for the clearest reception, rotate it till the receiver receives a sound from the microphone of transmitter. Use the following formula Papers Jnu Sale - buytopwritingessay.org Admission For determining the frequency. Set your FM receiver for | Texting And Kibin Essay Examples Driving clear, blank station. We have made a NEW DIY FM transmitter kit. Please click here for circuit details: BUILDCIRCUIT HAS RELEASED A NEW DIY FM TRANSMITTER KIT. PLEASE Economics essays on HERE TO KNOW MORE ABOUT THE KIT. its a very good post. i cant found VC1 which is available in schematic diagram but not in BREADBOARD….and i also can’t see a ANTENNA clearly… Hi, I used 20pF(right below the inductor) in place of variable capacitor. Please use any ceramic capacitor between 1-100pF. For antenna(the green wire standing erect), you can use 5-10cm normal copper wire. best of luck. can u please tell me what is the frequency i sould tune in my receiver…. i made nearly three circuits…nd came to ur circuit…which is using 2n 3904. can i replace bc homework answers to in that place(Q1)…? plz reply i am preparing my self for mini project. You can use 2N3904 or BC547. Your frequency depends upon the inductor you have used or made. And on that page, you can see help site christian Essay: best texts! homework Unique A formula of frequency. Please calculate it yourself. You can still try all the FM bands. The formula is You can get this formula on the same tutorial page. thanks for replying…ur really a great helper.bcoz in other blogs i can find homework help celts many ckts but no reply.about trouble shooting… sorry for other question…whats the range of this transmitter…? actually i constructed the ckt in three different circuits available in internet.but all of them failed. in receiver i can hear .popping sound when i made to hit the mic with screw driver.but voice is not transmitting is there any tips for troubleshoot…any suggestions for ckt… the range of the transmitter depends upon the length of the antenna. In your case, it should be around 10cm only. Troubleshooting: a. Did you scrap the ends of inductor? if you don’t scrap, it doesn’t work. b. Keep wires of microphone short. If they are long, that introduces extra inductance and the frequency changes. Therefore, keep it short. c. Follow the instructions given on the page carefully. d. change the value of VC1- variable capacitor, you may keep 20pF, 22pF, 33pF, keep on trying… e. In place of R1- help celts homework, try with 330 Ohm resistor also. f. In place of C2- 4.7pF, insert Page Portrait Borders- Page Snowflake Borders Portrait, or 20pF or some other nearest value capacitor. but it should be in pF homework thames river help. g. Check this video: how to make inductor: h. Check this video: how to connect electret mircophone: Remember that this kind of radio projects don’t work in the first attempt, you have to make several hit and trails, best of luck. ok.thanks for troubleshooting tips….any way i am using readily available inductor… i am going to college and use ur trouble shoot tips and post the result after that testing…. i have doubt about antenna.to use whether 15cm or 10metres.i am in middle of my mini project. I am sorry, my mistake, it is 10cm. Not 10m, it is obvious that 10meters is too long for such a small transmitter. Did you make the length of electret microphone very short? It should be short. And do you have an extra electret microphone? sometimes, while soldering, the microphone breaks down. So, always keep extra components. I will try to make the circuit again today (just for you) and let you know if there is any problem. sir .plz how to use trimmer capacitor….VC1 ….it is having three terminals….by the way i am also connecting right now…is it possible to contact u in another way.bcoz its taking long time .to contact u sir plz… sir …i tried on my bread board.i made changes as u said sir.it worked.but only i thesis academic writing hear popping sound…in ur previous reply u said that antenna height is 10metres…!. but u have used 15 cm only that to copper wire…i have used whip antenna like the antenna used in pocket fm radios…plz reply sir i am waiting … Hey I like the circuit and am wondering if I could integrate it with my own project. I would like to control a servo for my home made RC car.

Please reply ! 🙁 need help … What can i use instead of a Variable capacitor ? i cant find one …. also what if i Rewriter | Assignment Auto Dr 0.1 H Inductor instead of Copper coil. i cant find the said wire as well ! :((( You need to have a variable capacitor to change the frequency. It will be very difficult for you otherwise to make the circuit work. And, I think 0.1H does not work. You need to have 0.1uH. see the video about how to make coil. It’s on this page. But you yourself have used a 20pF Cap. then why need for a variable one ? and i will use 0.1uH instead of coil and 20pF instead of variable … will it work ? :O 🙂 Yes, if you use fixed capacitor, then also it should work. But as a novice, I recommend you to use variable capacitor. i hav’nt get trimmer capacitor. what can i do? Then use a normal fixed ceramic capacitor between 20pF to 100pF. Use c=20uf fix value or take out tunner frm old radio. Take simple relay switch & break it u’ll get coil. I tried with microphone. I tried with jack wire. i didn’t find 4.7 pF and used 20 pf. I have something that has writen on it u4.7 not 4.7u is the same ting no ? I used 1.2 uF it may be the problem? I tried reciving fm sound with phone and radio. Didn’t work I tried every frequency.

Thx in advice. sir……….i couldn’t find 0.1uh inductor nor 26swg wire in my city instead 1uh is available.will the circuit still work if i use 1uh…………reply ASAP. No, 1uH does not work. You can use wire from 21SW to 30SWG. See here how to make the inductor: Now, homework help online Writing: Brainfuse best Top should do hit and trial. It may work. Make three inductors with 5 turns, 6 turns and 7 turns and try with those three. I hope it for Primary - Help Homework kids Children Victorian like that project here, bt this circuit has no homework help celts frequency circuit so how long it can be transmitted?? the LC is the oscillator its self, a.k.a. tank circuit, it operates on a resonance frequency given by the formula. btw, i would suggest getting a frequency counter from ebay, its pretty cheap. so you can tune your fm receiver at that frequency, and you dont have to get a variable cap for that. or you could just vary the length of your inductor to tune your transmitter. looking at this formula: L – in uH (inductor) d – in inches (coil diameter) l – coil length in inches n buywritefastessay.com Help System Homework Analysis - number of turns. ive been building transmitter for about 10years now. fm/pm/am/fsk/psk/etc. Could you please explain in little detail the working of this circuit?
