Stereo FM receiver using TA7640 and TA7343
use a car's FM Tuner RF Frond End ICs as IF and IC TA7640 TA7343 as Stereo Encoder, results were very memuasakan resultant highly stereo sound separation of L and R sounds so obvious when 100% of its components come from the junk.
Stereo FM receiver using LA1260 and LA3361
FM receiver circuit redesign is the result of the Kit-Kit oft-sold in the market with IC LA1260 and LA3361 datasheets, so I think it produces better stereo sound ...
THIS is the circuit ...
After everything is assembled to PCB
Blue Tooth GPS Receiver - Turn Your PDA Into A GPS
Bluetooth is a new wireless technology to hit the market. This allows users to connect mobile phones, PDAs, laptops and all the various gadgets with one another to transfer data without cables boring and annoying. The time required to transfer files is the same as that required for the same email. Now it's only logical that runs in a Bluetooth GPS receiver will be created.
Now the GPS bluetooth receiver just changes your PDA into the GPS receiver itself. PDAs So now you can tell exactly where you are on earth. The main advantage in buying a bluetooth gps receiver is that it eliminates the need to buy a gps device itself. Bluetooth GPS receiver allows users to download a specific location on the map or instructions directly to the PDA. Previously involved with cable technology, now do not need cable.
It definitely helps to have a PDA compatible Bluetooth GPS receiver. If your PDA is not compatible, then the adapter can be purchased and inserted into your PDA or flash drive to any other suitable slots for the adapter. Now you may be thinking that downloading all of this data will not need to slow down and obstruct the PDA, but all the information that you download like a map and check point can only be loaded into the memory stick which in turn can be inserted into a memory expansion slot on your PDA. This leaves you free compact flash slot for connecting other devices.
Life is definitely easier when you also gps your PDA. Just place your Bluetooth GPS receiver while driving toward the heavens open and easy to find points of interest along your route whether it is restaurants, cinemas, hotels, hospitals and anything else that might want to know the way to or from. PDAs will be converted to display and easy to read that give you easy to read and understand the directions from your location to the destination you want. All of this without annoying cables into the crease!
With all these electronic gadgets to make life easier in the vicinity and created more and more everyday is a Bluetooth GPS receiver to make things easier on or off the road without your having to buy an extra gadget at all!

Experiment: A Simple Receiver - Radio Receiver AM
Today we will discuss how to create a Receiver / AM radio receiver is simple. Actually this is a tool that I made during the period of the Final Project and Practical Introduction to Telecommunications Systems chance drawings can be obtained with a complete picture of the Sci-Toys.com.
What ingredients in making this AM Receiver / Receiver Radio this AM?
1. Sturdy plastic bottle. Smoking's size ... but yesterday I was using for the project bottle apple juice remaining Sunfresh which has a diameter of approximately 7.5 cm. My advice try to be bigger than that caught more variable frequency.
2. A roll of coated copper wire with email. If the same confused way what the seller told . Why use a coated cable email? Simple, so that no short loops. When asked how the diameter of the diameter of the cord simply use I've tested that is 0.8 mm. Oh yea i thing, in Indonesia are usually old email will be golden yellow in color, so do not be confused to find the green wire as shown.
3. A germanium diode types. 1N34A type that is recommended , my advice is still do not see you can try to type 1N60A Same function, I have tried and can function properly.
4. A high impedance speakers. In this project we use the existing speakers in the telephone receiver, if you do not want to sacrifice your phone, just buy speakers that membranes of translucent colored plastic instead of ordinary speaker2 membranes from the barrier of black paper inside Impedance 8 Ohm only.
5. Some cable attached alligator claws. We use this much because we want to project this time free solder soldering.
6. Antenna. We can use anything for a long iron main antenna or cable can be used as a bare antenna . But I recommend using External TV antenna.

Part1. AM receiver coil (Receiver)
Make your bottle looks like the picture below
As many as two holes respectively on the bottom and the bottle, do not worry too good because it is only used as a place to tie the cable loops that had you bought.
Enter our coil cord and remove the bit length of the hole that only approximately 15 cm, if it is still rather loose one more repeat loop until cord loops can not move anymore. (Actually this is not too important, just make such a way that does not move when windings are made later.)
Now take a part of a long coil and wrap the body of the bottle. Every five loops make a small loop, so you can easily tuck it inside pencil's coil. repeat until touching the bottom of the bottle.
Have looked like in the picture? if so, do not forget to tie the end of the 2 nd winding hole below the bottle so that no loose loops ... then cut the cable at the end of the nd of equal length with wires protruding on the upper side of the bottle that is about 15 cm.
If you already Peel email attached at both ends of the cable that was 15 cm and a small loop on the loop that we created earlier, so that the original copper cable in sight.
Prepare also your telephone receiver, cut the cord and find the red and white cables.
Part 2. AM receiver circuit (Receiver)
Do not Confused to see the image above! diodes that wrap your purchases in a 15 cm coil wire at the bottom of the bottle with a black head of diode negative toward the speaker (white cables on the speakers). Connect the cable is also above 15 cm of positive bottles with Speaker (Red cable) and cable capitkan an alligator claw (claw Green in picture) at this nexus and capitkan the claws of one another on the same cable to the Grounding vera good (or Body Land you own).
Do not forget to mencapitkan a crocodile Fruit cable again to one loop in the coil (yellow claws), and capitkan other end to TV Antenna.
Do not forget to mencapitkan a crocodile Fruit cable again to one loop in the coil (yellow claws), and capitkan other end to TV Antenna.
Part 3. Testing
If all components are connected correctly, then when it is connected to the antenna and the Grounding which can be good we should be able to hear the radio broadcast.
Try to replace loop with loop tercapitkan beside it, then we ought to be able to hear radio broadcasts from a different frequency.

Create a Simple VHF / Aircraft Band Receiver
The circuit is very simple, but necessary experience in assembling the recipient this. This circuit can receive the frequencies from 140 to 150 MHz covering the frequency of 2 meters.There is a super-regenerative detector that can set this to be very sensitive receiver. This receiver can receive the transmission signal from a transmitter that is 10th mile, with only using 6-inch long cable.Recipients must be input into the metal box and to tuningnya using plastic knob. Do not ever assembled on the IC board or veroboard.
Windings L1 and L2 must be heavily using size 18 SWG copper wire to wire Click here to see the table consists of one winding L1, and L2 4 Circumference Conductor winding length (7 / 8 inch). Both these lilitabn air cored with a diameter of ½ inch. L2 should be in a relationship from the L1 point. By controlling the coil L2 spaces, will change the frequency, then you should do some experiments and find a desired frequency. L3 is not too critical, consisting of 30 windings of copper wire 26 SWG size with air core diammeter ¼ inch.
After all the well-Threaded and soldered perkawatannya connection, connect the output to the audio amplifier. Amplifier can use IC LM386 for the audio amplifier, or similar. Use a suitable antenna to the transmitter. Rotate the 25K potentiometer size, until the sound of a hiss that is strong enough, this marks the series has worked well.
Hissing sound stops when no signal is captured, from any signal. Set the variable capacitor 10 pF to find a relay station. In order to receive the desired signal, then the coils need to be adjusted. The frequency will be higher when the L2 stretched.
