Likewise, I find it unhelpful to criticize the hobbyist who has, at his disposal, a specific selection of components, that he use different ones when that's not the approach about which he requested help. In such cases, I believe the first thing presented should be a relevant answer directed specifically at his question, and, only after that's been presented should an alternative path be recommended. It should be up to the O/P to make a decision based on his own decision variables, and not on what someone else believes should be the basis for that decision. There are, after all, people who want to build a one-off, and want to do it with what they've already got, or what the supplier down the street has in local stock.
We know that a lot of people ask questions about the use of ancient - or improper - components because they did see some old design somewhere on the net, or they did a google and found the name of some old chip. It is normally quite meaningful to first establish if the choice of old components is because of the components already being available or because the task is seen as some form of challenge, or if the old/improper components was mentioned because the OP thought they where good components to use. After all, a very large percentage of threads are created to try to find the solution to the wrong problem. People are desperately trying to get assembler instructions into their C functions just because they have not noticed that their goal can be solved in pure C, or that looking at the assembler listing for the C function will allow them to take the C skelleton and modify into a 100% assembler function. People regularly try to put their variables at absolute locations for various strange reasons. People try to compute jump addresses instead of using the symbolic name of functions. There are a huge number of Gordian knots that people are a trying to solve. Should we let people drive over the cliff just because they think that going north is the best route, or should we ask them what their final destination is expected to be, and instead suggest that they take the bridge 2km to the west? |
