wise words by gubbin and kmp24
As in 'you've got it wrong, throw it away, start again' ?
Engineering is littered with mistakes along the way and electronic design is no exception. It is quite common to discover something has been left out of a circuit, only later find that something necessary wasn't included and it may not even be realised something is necessary when the circuit is first designed. This is the 'prototyping' all projects and products go through.
The circuits we find in electronics we use today will invariably be the result of a long process of 'getting it wrong' and modification to make them work. Soldering on extra components, connecting separate boards, cutting tracks and all sorts of 're-work' are part and parcel of the design process, and there's nothing wrong with that.
Where a board can be modified to make it work that's just as legitimate as starting again and is often more cost-effective and quicker than restarting, especially if PCB's or other boards have already been designed and built.
One wouldn't necessarily consider it wise to demolish a multi-million dollar building and start again because something fundamentally important was overlooked, it would be much wiser to consider how what exists can be modified to deliver what should have been included. If the end result is what was required in the first place it doesn't really matter how that is achieved.
Likewise, one doesn't usually throw their entire dinner in a bin because some of it burnt.
While there can be merit in restarting, it's not always necessary to do so immediately. Even with a restart more unexpected problems may arise which require further changes. It is usually better to get as much working as possible before a re-design or restart; that minimises both effort and cost and the number of restarts there may be.
Kushal901 undoubtedly "got it wrong", but has shown good initiative in the approach to working round that mistake. Sometimes there's no choice but to restart but other times it's not necessary to do so.
If you asked a room full of electronic engineers to put their hands up if they'd never made a mistake there would be very few who could. Many would say that anyone putting their hand up hadn't experienced enough to truly call themselves an engineer
