For you and me, sure. To someone with no electronics or programming experience, which is 1ronman's situation, that comment is not helpful at all; it just makes you look like a show-off.
In a Math class we might have only one or two 'A' students, a few 'A-' students, maybe some 'B+' , and surely lots of 'C' and myriads of 'F'.
If you set up an one to one session after the final exam with the students enrolled in that Math class, and ask about the quality of the exam, they won't answer the same. The 'A' students say the exam was very easy, and the 'F' students say that the exam was though, and keep complaining about almost everything.
The 'A' student does not show off. He/She just simply states his/her own perception regarding the quality of the exam.
I don't want to get deep into a philosophical debate on the topic of 'boastfulness', but in my opinion the world has enough slaves and zillions of humble people. What the world lacking is knowledgeable boastful people with enough courage to show off! ( This command : "be humble" has originated from some specific religions, but I really don't want to dig into such controversial topic. I am just not religious :-D )
So even if my intention was to show off, I am still doing OK!
The OP has stated that his friend has forwarded a drawing to him, asking him to make the circuit. Either his friend is out of his mind to send such a task (LCD, push buttons and I/O, controlling, etc... ) to a guy who is rubbish with circuits (which I doubt that's the case) or the OP just following the manner of being humble and tries to tell us that he is not that much good with electronics, but his knowledge is ok to accomplish such a task.
I assumed the second case is true, and I told him that It's easy, don't afraid, just use a micro-controller.
Perhaps you would like to offer to design, program, and build this very easy project. How much would you charge?
If the OP asks this question I will start estimating the time I need to spend on this project and I will offer a price (that's of course when I am sure that he is serious to hand me the project). But in this case I won't bother estimating the price of things.
Ehsan.
