*Super Simple FM Transmitter* is the latest addition to our beginner-friendly #WeekendProjects series powered by RadioShack: known as the "Manhattan style" for assembling circuits, use a copper-clad board as the ground plane and a small number of common components to build a local FM transmitter for your favorite tunes.

It's pronounced SolDER not 'SoDDer'... And it's actually point-to-point or rats-nest construction.

if someone was wondering and had these questions in mind: where exactly would u attach the antena for longer range? and how to set a station of where the audio would be broadcasted? don't worry i found the answers for you. 1- You can solder the antenna on the "free pad" (video 3:16) where the transistor emitter meets the 10pf capacitor and 470Ohm resistor (yellow, purple, brown, gold) 2- The frequency depends on the inductance of the coil and the value of the 10pf capacitors. The easiest way to adjust the frequency, for example to move away from a strong local broadcaster, is to slightly squeeze or stretch the coil. if you search online for coils and capcitors you will find a fromula that will help u get a frequency (thats what i remember from my electricty class.) hope that helps

I know how to make an FM/ AM transmitter with only one Transistor and one resistor and one capacitor and one variable capacitor aka knob to switch frequencies

Omg. This is what I needed. I searched everywhere but couldn’t find it. Thanks man. This just planted seeds in me for future bigger and amazing projects.

20 years ago I purchased an FM transmitter for some several hundred dollars. It was 130 Watt and covered a good radius. We were running pirate radio at the time. I opened it up and noticed it was a copper board with lots of hand soldered through-hole components. To this day I've always wanted to rebuild that and it's what got me started in electronics all those years ago. It looked very much like this, but larger, and there were some amps etc in there too. Very interesting stuff.

no experience with transmitters, only from the pass 3 months I have been doing research on DIY transmitters and finally this is the only one that works for me. WOW i love it. I didn't have 2 10pf caps so I used 33pf and it still works. thanks.

Very well presented - right to the point. This is a great adjunct to the Make: article, which has a parts list. The Radio Shack PCB listed is copper clad on both sides, so to get it to "snap" apart like in this video, you have to score the line on both sides. Probably the trickiest part of this project is to initially find yourself on the FM receiver, but once found you can "move" the frequency by squeezing or expanding the coil. Thanks for posting this project, Sean!

This is probably the best electronic circuit layout and demonstration I have seen. This gives a list of the tools you need and all the parts and even what they look like. This is something I would most certainly reference to in a college paper or any academic work.

Thanks for the coil winding tip! Have been an Amateur Radio Op since 94. Never seen this until now. John

Great narration and flow! The use of stop motion really helped keep the visuals clean and focused.

Good video. Old schematic. Usually drawn with 27k, 10k vertically as a voltage divider for biasing the transistor. Some might place a variable capacitor in parallel to the coil for tuning, not too big of a value or tuning will be touchy, just pops on the FM radio. You could place the variable cap across the transistor, from collector to emitter. Use of an oscilloscope would show the frequency change in the sine wave. A varactor diode could be used with a .01 cap anywhere a tuning capacitor is used. Tune with a 10 k pot. Add a 10k potentiometer where audio comes in for modulation control if input volume can't be adjusted. Left pot wire to audio source, center pot wire to input cap, (1-33 uf) and right pot wire to ground. Use an on line dipole calculator to figure out how long the vertical antenna needs to be for the frequency you choose. Go crazy and build a field strength meter! Get it close to your transmitter antenna to check radiated power. A needle moves as the indicator. Make sure you don't cause interference with radio, tv,'s, etc..Once I heard somebody talk over a juke box that was unplugged! Ham operator using too much power.

Hello, what type of transistor did you use in the circut, I am just curious because it dosent really specific in the video. Also, wher on it did you add the antenna?

Great beginner's project to get acquainted with hobby radio transmitters. Thanks for sharing.

Plugging a mono TRS connector into a MP3 player will short out one of the channels, which is not really what you want. Maybe it would be better to join both channels together using mid-valued resistors to a single mono signal and use this as the input to the transmitter

Many people like this, but would you please provide a practical demo of it. I expected your music to be fired through that receiver the last few seconds :)

OK, built it. I had zero electronic experience before this, but ordered the parts, followed the directions on the video to the letter, powered it up......and.......IT WORKS!!! I goofed up a couple of things, but I can correct those. It's broadcasting on 105.3 FM. It only has a range of a few feet, so I'm going to add an antenna and see if I can get it to broadcast 15-20 feet. Took me a grand total of about 3 hours, but I had a blast building it. Thanks for this most excellent video!

That's a blast from the past. My last local Radio Shack closed down several years ago.

As far as I can tell it translates the RCA electrical input signal to an electromagnetic one where the song's information is present in the variations of the frequency of the EM wave which is the interpreted by a Radio recziver and re-converted to an electrical signal to an amplifier and then speaker. The different transistors, capacitors modulate the electric signal, Amperage and voltage so it does it job in an optimal way.

Resistors are potential dividers. 10 pF collector to emitter capacitor is regenerative feedback. 10 pF from emitter to ground is bypass. 10 nF in parallel to two resistors are bypass as well so RF won't disturb the bias. Electrolytic capacitor is for coupling purposes. Transistor is an amplifier and inverts the phase by 180 degrees and remaining is done by the tank.

pretty cool

I built one like this many years ago, and at first I thought it wasn't working. But, once I had access to a frequency counter, I found that it was working quite well but not in the commercial FM band but instead it was too high and was in the aircraft band. Little bit of tuning and it was back to where it should be.
