soldering irons are not essential at the very beggining but will be needed when you want to take your breadboard project and build it permanantly on veroboard. Veroboard is a form of circuit board material with holes and copper strips you solder components to. In any case i good basic iron such as the Antex 25 watt can be bought for a around 20. * +

at some point you are gonna need to measure voltage, current, resistance and continuity. to do this your gonna need a multimeter. I highly reccomend you dont buy the really cheap ones because they are just cr*p. You want a reliable, safe, accurate meter. Go for a good brand like amprobe, extech, agilent, fluke, BK Precision. This will cost a minimum of 50 dollar, pounds, bucks. But theres no need to spend more than 100. * +

remember you can find good deals on ebay for multimeters and a good multimeter can be had for less than 100. * +

the power supply - for your basic projects batterys will do but will run out eventually, and if you build something that draws upwards of say 500 mili amps it can become costly because they will run out quickly. What you need is a mains power supply. You can buy a 1amp or 2 amp dc plug in wall adapter that puts out 12 volt DC. To step this down to other voltages buy a 1 Amp LM317 Voltage regulator, a 5K Potentiometer and a 240 ohm resistor. Do a google search for basic LM317 power supply for the * +

for the circuit. This will give you a variable 0 to 12 V DC power supply and it will cost you around 20 to 30. * +

you can buy proper lab bench power supplys but these are expensive and not needed in the begining. When working with digital circuits you will need a 5V Supply. Use a 7805 voltage regulator in this case. The exception is with 40x x x series cmos logic chips that can run a up to 12 Volts, but standard 74lsxx series logic chips must use 5Volts. * +

when setting the voltage on you variable power supply leave the output unconnected at first! Now set your multimeter to volts and connect to the output of the powersupply and read the voltage while adjusting it to the voltage you require. Then connect your circuit. * +
