Starting Today we will present you once a month the top 10 electronic articles that had the highest views and appreciation in the past month.
We start today by presenting to you December top 10 articles ordered ascending by number of views and comments.
Top 10 Electronic Circuit Articles
- 12V to 220V converter
This 12V to 220V converter is build with CMOS 4047 that is the main component of this small voltage converter that transforms a 12V DC into 220V AC.
- Audio Mixer Circuit
A 3 channels audio mixer circuit that uses an LM3900 IC but is not a professional audio dj mixer but has the advantage of using a single power supply.
- Digital TV Antenna
Do you really need a “digital tv antenna”? Digital TV Antenna is used to receive digital TV signals and is no different from a conventional off-air TV antenna.
- Electronic muscle stimulator
An electronic muscle stimulator circuit that stimulates nerves of that part of your body where electrodes are attached.
- Voltage Doubler Circuit
A Voltage Doubler Circuit with 555 that produces a voltage that is twice its voltage supply. This is useful when a higher voltage level is needed out of a single lower voltage power supply.
- Robot Voice Generator
Those of you who imagine that a robot voice generator box would require a whole heap of ICs are mistaken.
- Simple Metal Detector
The metal detector circuit shown there must represent the limits of simplicity for a metal detector, yet the design works surprisingly well.
- Sound Activated Switch
With this sound activated switch, control by sound may be very useful, not just on a robot but also for a bit of home automation, for example a sound-activated light.
- Temperature Alarm
This temperature alarm circuit continuosly monitors the room temperature and beeps when the temperature drops below 20 degrees centigrade.
- Electronic Mosquito
It behaves like a true mosquito: once the light dims, the mosquito starts an annoying buzz. When its light again it becomes mute, so that, as in the case of genuine mosquito is very difficult to spot.
