Working in the Laboratory :Why it is not simple?

Oh..!

Working in laboratory is not at all simple. There are technical and non-technical problems which make me stay away from touching real physical elements.

The most difficult problem is when I leave the paper,pencil and computer the thinking mood changes and some time I confused to see what i need to do.The searching of wanted component in lab shelf is always a difficult task. If the last lab task had finished in hurry way it is likely that old lab set may be in place and need to shift the component back to shelf.

Once I was working on pcb in hurried way and the ferric chloride spread out in the room. The whole room tiles were shining(waw..!) with yellow patches.Ferric chloride is a acid and needs to be careful while handling.

Computer work can be saved and done in any time. However lab task can not be stopped in between and continuous time availability is very important. I am recalling now that digital clock pcb soldering in my engineering college days which had taken continuous 30 hours to finish it.

Working in the lab is interesting if our intended circuit works in 2 or 3 approaches. However, even simple circuits will not work single shots. The problems may be wrong connections,loose connections, wrong concepts,wrong testing methodologies, or any other "wrongs". 

I find another difficult when a circuit or project involve mechanical parts. Most of the times the circuits end up with controlling few mechanical parts.Example: Water tap controller is circuit need to have some mechanical arrangements in order to place in practical use. I am fed up with how to go ahead with mechanical assembly of things.A grain shutter circuits(a circuit detect the rain and cover the grains which are kept under the sun) is still on breadboard and not able to transfer as practical idea as there is difficulty to fix the motor to mechanical parts.

However, working in a electronics lab is a happiest moment.Electronics engineer can give life to inanimate things and make magic out of it.I am proud to say I am a hobbyist in electronics.
