Every Engineer who loves to tinker with electronics at some point of time would want to have their own lab set-up. A Multimeter, Clamp meter, Oscilloscope, LCR Meter, Function Generator, Dual mode power supply and an Auto transformer are the bare minimum equipments for a decent lab set-up. While all of these can be purchased, we can also easily built few on our own like the Function Generator and the Dual mode power supply.
