Hi All

Well i finaly managed to get to Maplins today ,,This is what i came back with
A small breadboard and some jumpers,,


and a GCSE electronics kit



I no a few of you lads don't like breadboards ,but i thought i would give it ago for putting together  basic curcits,and i can sit on the sofa in the warm and fiddel about with it  :D

Cheers Rob and i hope everyone has a great new year

John Rudd:
Wise move there Rob, the plug in boards and wires will help you quickly build and change...

The strip board isnt as versatile and you need to master the art of soldering.....

Enjoy! :thumbup:

Rob.Wilson:
Cheers John

I thought it would be the best way to go ,as i will be able to re-use components as i go along , i will move on to the strip board when i start to get to grips with things ,
Now that strip board has been mentioned ,,i notice in the shop it comes in all sort of sizes , i take it you cut it to size,,,Whats the best way of cutting it up ?

Regards Rob

Rob,

It can be cut with a hack saw either along the tracks or across...If you need to make breaks in the tracks to segregate signals/components etc, use a small drill bit, around 1/8 should do..But...you must make sure the break is clean..ie there arent any 'whiskers' of copper. I use a small mag glass to check ( my eyesight aint what it used to be.. :dremel: )

Another tip, if you need to make wire bridges to jump from track to track, Maplin sell some solid copper wire, bit like the flexy stranded stuff..just strip the pvc off, straighten with a pair of pliers..

Rob,

Very nice start. May I suggest a vairable DC power supply to power the projects. A supply that will supply from 0 to 12V DC max would be a great start.

But here's an idea. Look for plans for a simple power supply that will give you the voltage that you'll be working with to make your circuits. This is usally one of the first things a person new to electronice would build. It will give you insight to where and how a power supply works.

Cutting the boards can be a bit tough. They are usally made from fiberglass and will dull HSS tools fast. For one or two cuts HSS tools are fine but for more I would look into a carbide saw.

Let us know how you make out with a power supply.

Bernd
