The objective of this construction project is to build a simple and easy to use Opamp Tester. This test gadget can be used to test the popular general purpose opamp type 741 and other such opamps that are pin to pin compatible to 741.These include the opamp type numbers much as LM 709, LM 201, [...]

The objective of this construction project is to build simple and easy to use test gadget that can be used to identify good and bad IC TIMERS from a given lot. Like opamps, an IC timer is another widely used electronic device and it finds its place in almost every project of hobbyists’ interest. This [...]

Thyristors (SCRs, Triacs) are very popular in AC power control applications where they are used to provide an active control of the AC power being fed to the load. The load here could be anything that is operated from AC mains and whose parameter to be controlled happens to depend upon the amount of AC [...]

Under previous posts, we have already seen how a bipolar transistor, NPN or PNP, can be used as a single pole, single throw switch. The transistor operating in saturation region with voltage across the switch being about 0.2 volt represents the ON-condition of the switch. The transistor operating in the cut-off region, where the only [...]

The objective of this simple exercise is to demonstrate the operation of solid state (or electronic) switches using electronic devices like TRANSISTORS or SCRs. There are many more electronic devices that can be used for the purpose. We have chosen these two as these are the most commonly used ones in this role, more so [...]

Majority of Electronics enthusiasts and hobbyists wants to build their own AC-DC power supplies to test the electronics circuits built by them. The objective of this easy to build and understand circuit is to familiarise the constructor or the hobbyist with the effect of changing the rectifier-filter configuration on the DC output voltage produced in [...]
