Beginners Projects

This simple shortwave transmitter is easy to construct and can be used to transmit speech on the lower shortwave (SW) band of 5MHz to 12MHz with appropriate choice of crystals. It...

Engineers are always in search of projects, and finding meaningful projects makes that search worthwhile. Listed below are some electrical engineering project ideas for such engineers. A lot of them may...

Total Dissolved Solids (TDS) is a measurement for detecting the potability of water. Both humans and aquatic creatures require a suitable level of water content to survive. TDS value > 1000...

Nameplates are generally made of wood, acrylic sheet, or a metal and fixed on a wall or kept on desk. The author’s prototype of an acrylic nameplate that can display the...

This Android-based project can monitor on-site (field) process data sensed by two temperature sensors and display the temperature (in degree centigrade) on a smartphone. The authors’ prototype of the project is...

This circuit of single-cell LiFePO4 (lithium iron phosphate) battery charger is based on an LM358 operational amplifier (op-amp) and a couple of inexpensive and easy-to-get components. It can be powered from...

Here is a simple stereo audio amplifier that can be made using a TDA1517 IC. A 14.4V regulated voltage is used as power supply for this amplifier. TDA1517 is a 9-pin...

This circuit uses power bank and DC-DC booster module not only for charging mobile devices but also to provide 1.2V to 37V DC power supply. The compact circuit can even be...

This circuit produces a rotating-wheel like LED lights pattern, which can be used to decorate public halls during parties, festivals, and marriage functions. The concept is based on the persistence of...

This simple stereo audio amplifier is based on a 12-pin TA8207K IC, which is inexpensive and easily available. In addition, it requires only a few resistors and electrolytic and ceramic capacitors....
