For those who like to design and build there own Crystal Radio set ( Xtal Radio Set ) we sell the parts (1N34A Diode, Ceramic Earphone, Piezoelectric Earphone ). The 1N34A Diode is the diode of choice for Crystal Radio Set Receivers sometimes called a Crystal Diode. The 1N34A, 1N60, 1N270, are germanium point contact diodes. These are sometimes called Crystal Diodes and as such some call a Crystal Radio Set a Crystal Diode Set.
Building Crystal Radio Kits ( Crystal Diode Radio Kits ) are a great way to introduce young people to electronics. My Simple Crystal Radio kits are easy to build and Crystal Radios do not use external power sources other than an antenna and ground. The principles of a Crystal Radio Sets operation are not hard to understand.
A Crystal Radio Receiver requires a good antenna and ground for the crystal radio set operate properly. This is because the Crystal Radio Receiver needs about .2 volts to be generated in the Crystal radio set tank circuit. Building a Simple Crystal Radio Kit is great for children of about 13 years old to learn Crystal Radio Set building and how a Crystal Radio Receiver works. I say 13 years old because our Crystal Radio Kit requires some soldering.
Some of the crystal radio kit parts are no longer sold or made in the USA any more. Crystal radio parts are becoming harder to find. Like Ceramic Earphones ( Piezoelectric Earphones ). You can buy however most of the hard to find Crystal radio supplies here. We keep a large supply of Crystal Radio Parts in stock. Use us as your number one Crystal Radio Resource for Crystal Radio Earphones ( Crystal Earphones ) Crystal Radio Earpiece, 1N34A, IN34A, Crystal Radio Coils, Crystal Radio Variable Capacitors, 1N60, 1N270 and Simple Crystal Radio Kits, supplies, components and Crystal Radio parts and Crystal Radio Ear buds.
Science Fair Crystal Radio Projects
Building Crystal Radios have been very popular as a Science Fair Project for years. A Crystal Radio Science Fair Project teaches many fundamentals of electronics. Many parents built Crystal Radios as there Science Fair projects when they were in school and want there children to build a Crystal Radio Set and enjoy all the fun they had learning how the Crystal Radio Set worked.
If you are thinking of building a Crystal Radio Kit as a Science Fair project then our Simple Crystal Radio Kits are a good choice. Our Simple Crystal Radio Kits come with all the components needed to make the Crystal Radio Receiver. Optional components are the Knobs, Fahnestock clips. The mounting boards and Antenna and Ground Wires are not included.
If you want to build a more elaborate Crystal Radio Science Fair Project maybe winding your own Crystal Radio Coils like the Quaker Oat Box Crystal Radio then you can purchase some of the hard to find Crystal Radio Parts here from our wide variety of Crystal Radio Resources and Components like Crystal Radio Earpieces. Some Quaker Oat Meal Box Crystal Radio Supplies I sell are magnet wire and Solder Lugs. Email me if you have any questions on what to purchase for your Crystal Radio Science Fair Project. Quaker Oat Box Crystal Radios supplies can be purchased here. I will also be making my own type of Oat Box Crystal Radios later on this year. My Oatmeal Box Crystal Radio will not require the taps on the coil and my Oat Box Crystal Radio work better and be easier to make than the other types of Oatmeal Box Crystal Radios on the internet now.
I now have for sale severial Simple Crystal Radio Kits. These Crystal Radio Receiver kits now come with Crystal Radio Coils with taps. My Simple Crystal Radio Kit #1 has one tap on the bottom of the Crystal Radio Coil for connecting a antenna no need to wrap wire around the coil for a antenna connection. The other Simple Crystal Radio Kit #2 has a tap towards the bottom and a center tap. The bottom connection is for the antenna and the Center connection gives better selectivity at a slight loss in volume. The top connection gives most volume but selectivity is reduced a little. Crystal Radio Kit #3 has no taps on the coil.
These are Simple Crystal radio kits ( Xtal Radio Kits ) and are easy to build. These Crystal Radio Receivers tune the AM Radio Band.
The Crystal Radio Kits ( Xtal Radio Set Kits ) requires some soldering of the fine wires from the Ferrite Loopstick Antenna Coil the the variable capacitor. So Adult Supervision is advised for younger Crystal Radio Set ( Xtal Radio Set ) builders.
Learning how to build a Crystal Radio is a great way for anyone to get started in the electronic field. Great for Science Fair Projects and Boy Scout projects. The Simple Crystal Diode Radio Sets we have for sale are a fun way for the family to spend time together. As a child I made Crystal Radio Receivers out of things I find in old scrapped Radios and TVs. Most had no tuning capacitors. I had to tune in stations by sliding a ferrite rod in and out of the tuning coil. I would spend days trying different items to use as a detector instead of a diode, some worked but most did not. Anyway I had fun learning. Buy one of our Crystal Radio Kits for hours of fun and learning.
Crystal Radio Set Kits are sometimes called Xtal Radio Set Kits and Crystal Diode Radios.
1N34A diodes are made of a material called germanium a material used for transistors and diodes as one of the first semiconductor materials used commercially . 1N34A Germanium diodes are becoming hard to find I try to keep in stock around 5000 in stock at all times. The 1N34A Germanium Diode the diode most used in Crystal Radio sets ( Xtal Radio Sets ).
I have a large supply of other types of Germanium Diodes other than the 1N34A . These included the 1N60 Germanium Diodes, 1N270 Germanium Diodes, 1N277 Germanium Diodes. Next to the 1N34A in popularity with Crystal Radio Set builders is the 1N60 Diode. The other diodes ( 1N270 Diode, 1N277 Diode ) can be used in Crystal Radio Sets ( Xtal Radio Sets ) but are not used as much as the 1N34A .
Crystal Radio Receivers depend on the 1N34A Germanium Diodes rated Forward Voltage Drop ( The amount of voltage before is starts to conduct ) of .3 volts. Silicon diodes are rated around .7 volts. However the voltage for the 1N34A Diode is measured with a current around 10ma. As the current increases so does the Voltage Drop and vise versa . However the 1N34A Germanium Diode actually starts to conduct at very low voltages. The 1N34A will start to conduct around .1 volt. So in a Crystal Radio Receiver you need only to produce around .1 volt from your Crystal Radio Set to begin to hear a station. That is the reason the 1N34A Diode is so popular with Crystal Radio Set Builders.
This 1N34A Germanium Diode and a ceramic earphone and a tuning coil are all that is needed to make a simple crystal radio set .
Because Crystal Radio Sets use only the power coming from the antenna a good antenna is required to drive the earphone of a Crystal Radio Set . If you live in the city close to a transmitter antenna then you should be able to pick up that station on your Crystal Radio Set ( Xtal Radio Set ) with only a short antenna wire.
The 1N34A Germanium Diode is an improved version of the 1N34 diode the only difference is the 1N34A is rated at a higher voltage. So any circuit that specifies a 1N34 Germanium Diode can be replaced by a 1N34A .
1N34A Diodes are some times called Crystal Diodes. And sometimes referred to as IN34A Diodes or Germanium Detector Diodes. And thus the name Crystal Diode Radio Sets is used by some used instead of Crystal Radio sets.
1N34A Diodes are used in may other circuits besides Crystal Radio Sets. Because of there low forward voltage drop they have found uses in Sound Effect Circuits and Voltage Dropping Circuits. However the use of the 1N34A in Crystal Radio Sets are one the most common uses I know of. The 1N34A Diode is the one supplied in my Simple Crystal Radio Kits.
The 1N34A Germanium Diode is no longer made in the United States to my knowledge. There are only about three manufactures of the 1N34A Diode that I know of World Wide. The 1N34A Diodes I sell are of highest quality. I have sold 1000's 1N34A Diodes and not one bad 1N34A that I know of. You can Buy 1N34A Diodes from me with confidence.
The 1N34A also is very popular in Crystal Radio, Ham Radio and Amateur Radio circuits. They are used as detectors and in up converter and down converter circuits ( Mixers ). The 1N34A is also a good RF input bypass or shunt to protect there equipment for voltage spikes.
The 1N34A is also very popular in sound effect circuits acting as a clipper to produce Fuzzy sounds and various distortions. Guitar sound effect circuits and Pedal circuits often specify these.
The 1N277 not used as much as the other germanium diodes in Crystal Radio, Ham Radio and Amateur Radio circuits but has high voltage rating making them very good for shunting the input to a radio receiver.
I did a lot of research to find this diode (Schottky Bat-46) actual has a lower forward break down voltage than a germanium diode at less than 10ma it has a forward voltage of .25 germanium has .35 volt.
I have only a limited supply of the Schottky BAT 46 diode. AT present over a 1000 in stock.
Experiment with the Schottky BAT46 diode in your next crystal radio set ( Xtal Radio Set ) project.
The Schotty Barrier Diodes are becoming ever more popular in Crystal Radio, Ham Radio and Amateur Radio community. The are being used as up converters and down converters ( Mixers ) and a host of other applications in radio and RF circuits. Generally replacing the germanium type diodes.
The Ceramic Earphone ( Piezoelectric Earphone ). It works good in Crystal Radio sets ( Xtal Radio Sets). The Ceramic Earphone is a high impedance earphone. Its DCR is greater than 20 million ohms. This is more than enough for Crystal Radios ( Xtal Radios ). These are sometimes called Crystal Earphones or Crystal Radio Earpieces.
These Ceramic Earphones instead of having a coil in them they operate by a Diaphragm coated with a ceramic material that deforms when a voltage is applied to it. This is called the Piezoelectric effect and thus the name Piezoelectric Earphones or more commonly Ceramic Earphones ( Crystal Earphones ). This makes them excellent Crystal Radio Earphones.
New High Impedance Ceramic
Headphones. The Crystal Headphones are driven by a Piezoelectric Element. The
Headphones have an DC resistance of 20 Million Ohms. They are some times called
Sound Powered Crystal Radio Headphones.
There are plenty of websites explaining how to make your own Piezoelectric High
Impedance Headphones. These High Impedance Ceramic Headphones were made special
for me from a manufacturer of Headphones. I repeat these are not Homemade,
Antique or Vintage Headphones they are New Factory Fresh.
The Piezo Headphones have excellent volume when used in a Crystal Radio Set.
They can also be used in any circuit or device calling for Ceramic Earphone
besides in a Crystal Radio.
So if you are looking for ready made Crystal Radio High Impedance Headset this
very hard to find Piezo Headphone is for you.
These High Impedance Headphones have a 1/4 inch
mono plug end and the cord is about 40 inches long.
The MK484 MK-484 MK 484 is a AM radio receiver IC has automatic gain and up to 72 db gain. It is cased in a TO-92 Case looks like a transistor. The MK 484 runs on 1.1 to 1.8 volts so a single 1 1/2 volt battery will work. Also the MK-484 needs a tuning Capacitor and Ferrite Rod Coil or also known as a loopstick antenna we sell both items.
The MK484 Kits are TRF ( Tuned Radio Frequency, Tuned RF ) type receivers. This the most basic type of radio receiver with no regeneration or re-genitive feedback. The variable capacitor and antenna coil form a "Tank" circuit that tunes the radio stations frequency then the MK484 amplifies the radio stations radio frequency then "Rectifies" (Converts to Audio) it then amplifies the audio and powers the Earphone, The MK484 kit is about as simple to make as a Crystal Radio.
Mono 2000 Ohm High Impedance Headphones with 1/4 inch plug ends. The High Impedance Headphones have an Impedance of 2000 Ohm. The cord is about 30 inches long.
My crystal radio set with a 12ft antenna connected to it will operate the 2000 Ohm High Impedance Headset without the use of a matching transformer and the sound quality is much better than the sound from my ceramic earphones.
Because my primary sales are for Crystal Radios I sell these 2000 Ohm Headphones as Crystal Radio Headphones. However many Amateur Radio and Ham Radio operators use them.
2000 Ohm High Impedance Headphones are rare and hard to find. Most are older or antiques. These High Impedance Headphones are not studio quality but intended for general use and listening.
These High Impedance Headsets are light weight and have foam covered Headsets.
The 2000 Ohm High Impedance Headphones makes them usable with my MK484 AM Radio Ic without a audio amplifier. However a amplifier will produce much more volume.
If you decide to make your own Crystal Radio Set ( Xtal Radio Set ) remember that radio waves are all that drives the Ceramic Earphone so a good antenna should be used between 50 and 100 ft. If you live near a transmitter tower like I do then a short piece of wire will do for an antenna. So the use of a good Crystal Radio Earphones is necessary.
These Ceramic Earphones are also good for other electronic devices other than Crystal radio sets ( Xtal Radio Sets ) due to its high impedance. The High Impedance Ceramic Earphone will allow you to power the Ceramic Earphone with very little power usage saving on batteries. These types of Ceramic Earphones are becoming hard to find. Look around my different sites and see if there is anything else you would like to purchase by clicking on the " Back to Homepage" link below.
Crystal Radio Earphones ( Piezoelectric Earphones ) are no longer made in the United States. There are just a few manufactures of Ceramic Earphones still in business world wide.
I keep a large supply of Ceramic Earphones (Crystal Radio Earpieces) in Stock. I am one of the leading suppliers of Crystal Radio Earphones. Because of the volume of these I sell my prices are very competitive.
I also sell Crystal Radio Set Supplies other than Crystal Radio Earbuds and other electronic parts on my Home Page. And a few Simple Crystal Radio Kits. Also High Impedance Headphones 2000 Ohm Impedance.
356 pf Air Variable Capacitors. The 365pf Variable Capacitors were very common years ago. The 365 pf capacitors were used in every radio. Now the 365pf Variable Capacitors are becoming hard to find.
The 365pf Variable Capacitor is very popular with Crystal Radio Set ( Xtal Radio Set ) builders. The 365pf Variable Capacitor is still popular with Crystal Radio and Ham Radio enthusiasts using them in all kinds of electrical circuits.
These were also known as 365 mmf air variable capacitors.
These 365pf Air Variable Capacitor are good quality ball bearing front shaft.
Ferrite Loopstick Antenna Coils or Crystal Radio Set Coils (Xtal Radio Set Coils ). These are very popular Crystal Radio Coils but can be used for other purposes.
These are known as Ferrite Rod Loopstick Antenna Coils used in AM radios and Crystal ( Xtal ) Radio Sets. These are also known as a Antenna Coils, Ferrite Antenna Coils, Loopstick or Loop Stick , Magnetic Antenna Coil, Ferrite Rod Antenna Coils, AM ferrite Antenna Coils, Ferrite Rod Coils. Crystal Radio Antenna Coils. Crystal Radio Coils.
I sell these Crystal Radio Coils in two different values 680uh, 788uh. The 680uh comes in two forms one is on a round ferrite rod 10mm in diameter and 60mm long with no taps that is about 3/8 inches in diameter and 2-3/8 long. The other two are on flat bars 5mm X 12mm X 55mm long.
The coils are wound with Litz type wire for a higher Q than solid copper wire.
We sell transistors MPF102 JFET , J309 FET, 2N2222A , 2N2222, PN2222A , 2N3904 , 2N4401 , BF981 , MFE201 , 2N3819, 2N3906 , 2N4403 , PN2907A .
Some of these transistors are becoming obsolete like the 2N2222A , 2N2222 , . The 2N2222A or the 2N2222 transistor in my opinion is almost a universal transistor good up to at least 300 Mhz.
The PN2222A transistor is about the same as the 2N2222A or 2N2222 except it has a lower power rating.
The MPF102 JFET is a VHF hi impedance device. The MPF 102 JFET can be used from audio to about 400 Mhz.
The 2N3819 JFET is another hi impedance device like the MPF102 the 2N3819 is also good from audio to VHF/UHF .
The J309 FET is another hi impedance device good form audio to VHF/UHF only manufactured to tighter tolerances than the 2N3819 and MPF102
