Simple and Cheap Indoor TV Antenna

Simple and Cheap Indoor TV Antenna: I haven't had a cable TV for the last several years since I found my family didn't need so many (too many) channels and could watch handful of channels for free through antenna. It's called OTA (over the air) channels. You may have to give up some...

Micro Transmitter Bug

Presented FM transmitter bug is built using BF414 / BF324 / BF606 transistor. The 30cm antenna has a range of about 30m in the building, more in the open field. Power supply 2x AAA batteries have been used with voltage of 2.75 V. I added resistor 10K in parallel with 1.5pF capacitor so that the system works well when connected to an external source (mp3 player / computer). On the computer I had to reduce sound to about 35% of capacity, so that I do not have clipping. I managed to improve…

The Simplest FM Transmitter... Without Coil/inductor

The Simplest FM Transmitter... Without Coil/inductor: I made this project three years ago, and it works perfectly. I have found the circuit of this project in a book I bought eighteen years ago when I was in high school. Most of the available FM transmitter circuits have, in my opinion, a very import...

Sensitive FM Transmitter Bug

This easy to build FM transmitter bug can transmit voice to exceptionally good range. Tune trimmer to hear the signal to your near radio. Transmitter frequency range is 88-108 MHz. Max current consumption is 30mA. You can power the fm transmitter bug with a 9Volt Battery, or you can plug a power supply to feed in 9-12 Volts. That bug will pick even a low whisper or even the sound of a breath well far from the microphone. Great spy transmitter equipment.

If you enjoy building radio projects you may have noticed something slightly worrying over the last few years in your component supply. Variable capacitors are no longer as plentiful as they used t… Diy Electronics, Electronics Projects, Antenne Fm, Radios, Radio Amateur, Ham Radio Antenna, Fm Antenna Diy, Diy Tech, Electronic Engineering
