He's making a one off for use at home, not commissioning a new design of military hardware.


The task is the same no matter who the customer.

Rubbish. For a large project all the specs have been calculated to meet the requirements, the contract gone through by a team of lawyers, and the task of the lec eng is to produce a circuit that meets all the given specs under all specified conditions.

For a one off at home the requirements are often not pinned down firmly, as in this case. There are no lawyers, no contract, and the elec eng's job is to trade off cost & complexity versus specs to find what turns out to be the most agreeable compromise for the client, oneself. In most cases this is a device that is much less tightly specced.
