Please log in for more thread options Hi Everyone, i am starting an electronics lab for myself. I have come up with the most basic things that I would need and I will be grateful if you guys can suggest adding or deleting the list from your experience. thanks List: Breadboard (Is is advisable to buy self powered or buying a separate power supply?) Multimeter Wire kit/jumpers Oscilloscope (What are the cheapest options available?) About the components i am going to buy them as I make circuits. Your suggestions are most welcome. Thanks | ||||||||||||||||||||||

+/-0 to 15V @ 1A adjustable, and several fixed voltages (+5V 2A, +12V
2A) are the minimum you'll need. > Multimeter
Get one that measures capacitors. Inductance can be handy too. > Wire kit/jumpers
> Oscilloscope (What are the cheapest options available?) Second hand on eBay is the best option. A 20MHz dual channel analog is a basic requirement, although 50-100MHz ones can be had cheaply too, some people even throw them out. If you ask nicely on the groups telling them what a keen beginner you are you might get one for nothing! ;-) Remember that you won't be able to view a 20MHz square wave on a 20MHz scope! > About the components i am going to buy them as I make circuits.
> > Your suggestions are most welcome. Thanks Add a function generator (sine/square/triange to say 2MHz). A logic probe if you work a lot with digital stuff. You basically need the ability to generate signals, view signals, measure stuff, and power stuff. That is covered with those 4 basic instruments mentioned. On the component side, get lots of "kits" and "grab bags" that have 10 or 100 of every value. Dave :) | ||||||||||||||||||||||

I'd recommend a solderless breadboard that comes with an internal power supply that's variable. Often it will have two separate adjustable supplies, so you can use them for circuits that require positive and negative voltages, such as op-amps. Such a breadboard will likely also come with an internal function generator, which produces several different waveforms (sine, square, triangle) whose frequency you can also adjust. This greatly simplifies things. Heathkit made some very good ones, and perhaps you can find one on eBay. But of course plenty of other manufacturers made such items. | ||||||||||||||||||||||
