Many of you might love to visit electronic marts and check out the new gadgets that are in display. It could be a LED torch light powered by a dynamo, a simple timer circuit or anything interesting. Some of you might as well buy simple circuits and construct your own hobby circuits which could help in simplifying your house hold activities like a touch sensitive switch circuit, an automated light that can be powered on and off with heat sensor, audio power amplifier circuits, water level alarm, temperature detectors, night lamps, emergency lamp circuitry etc. Each of these circuits are easy to construct if you are aware of the technical details that goes into building one from scratch. All you have to do is to select the electronic devices required to build these circuit boards design you have made and then get into action. So, how to choose the components for building these circuits? Here are some quick tips that will help you through the process. Have a look on them and get inspired:

Optimal pricing

Price of the components should be inspected before buying them. Check multiple vendors and also analyse if buying in bulk would be a better option for you compared to buying a single component. Always choose components that are priced optimal which is good in a way as there will not be a major loss from your pocket if the circuit turns out to be flop design.


If you are looking for programmer devices, always choose the electrically erasable PROM which can be partially erased and written all over. This also helps to re-use the device numerous times quite easily and you needn't to buy a new one every time. Designing memory circuits, making a configuration storage circuit etc. require a re-programmable component in its design.

Multi device adaptability

It is mandatory that the components have multi device compatibility and adaptability so that programming is easier and quicker. The component specification document will list what are the devices available in market to which the component is compatible. Check for this prime information and then order your component online or purchase them wholesale. If you miss out to check this vital information, later on it can create problems for you.

Easy to upgrade or replace

There are programmable microcontrollers which can be upgraded using software from their manufacturers. Hence, while looking for a PIC programmer, always choose the one after carefully assessing its technical specifications. These devices form the base of any business logic and hence you should not be in a haste to grab any EEPROM programmer or a PIC controller and rush home. Though there are a number of cheap eeprom programmers which you can easily buy from online stores, you should check well before making the deal.

These are some simple checks that can be performed on the components before purchasing them in bulk. Even if you are checking out for a resistor or a capacitor it is required to check the component properly as it should not get damaged quickly while experimenting. Another quick tip is to buy these building blocks in bulk so that even if one fails you can replace them and finish your circuit. After all your circuit is your pride!
