It is time to show you the April 2013 top 10 of electronic circuits from electroschematics.com. April was a great month with new projects published on regular basis and on Facebook we are almost 10.000 friends.
Top 10 Projects
Automatic battery charger
A 12 volt lead acid automatic battery charger that shut off the charging process once the battery attains full charge.
Solar charge controller
This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator.
Solar battery charger
This is the most simple and affordable solar battery charger that the hobbyist can make. It has a few drawbacks over other similar controls, but offers numerous advantages.
The solar tracker circuit uses a window comparator to maintain the motor in a idle state as long as the two LDRs are under the same illumination level.
Gas leak detector
A gas leak detector circuit that detects the leakage of LPG gas and alerts the user through audio-visual indications.
It is often required to switch electrical appliances from a distance without being a direct line of sight between the transmitter and receiver.
Time delay relay
This time delay relay circuit is built with IC NE/SE555, produced by Intersil which contains a precision timer.
AC to DC converter
This AC to DC converter circuit is capable of converting an alternative voltage within 70V – 260V range into a DC voltage within 180V to 350V DC range
Outdoor Solar Lights
This Outdoor LED Solar Garden Lights project is a hobby circuit of an automatic garden light using a LDR and 6V/5W solar panel.
Energy saving lighting
Faced with the situation to control the time that the light is turned on, engineer Radu Preda from Romania has started experimenting with different circuits to save money spent on electricity.
