Hello Everyone!

Hope you are all doing well. I’m excited to announce that this month's AskE14 question is: What is the worst mistake or problem you've encountered during a project, and what did you learn from it?

Sharing your experiences can help others identify similar challenges and understand how to overcome them. I hope this discussion will be beneficial for those who are just starting out on a project or feeling stuck with a problem.

Here's the question:

What’s the worst mistake/problem you’ve made during a project, and what did you learn from it?

    My first rude awakening on the job was building a linear regulator to output 4A at 5V with a car battery as the input. I used a 2N3055 (TO3) as the pass transistor because it could handle 15 Amps and 115…

    My worst project mistake? I guess I would say trusting a breadboard connection that “looked fine.”

    I spent hours debugging firmware, rewriting code, and questioning my life choices… only to find one jumper wire sitting half a millimeter out of the socket Slight smile.

    Lesson learned: in electronics, 90% of problems are either power, ground, or a wire pretending to be connected.

    Yes, breadboards can be insidious - especially when contact deforms after inserting goldpin connector and is only pretending to hold e.g. (thinner) resistor wire afterwards... And try to find this problem when it appears...

    Haha, very true. Breadboards are just so good at looking completely innocent and ruining your day. The worst part is when everything works after you poke it with your finger and it’s just been begging for your attention all along.

    But it may be some troubleshooting method - pressing different parts of circuit to check when the behavior changes, then examine every one contact in the suspected area...

    That’s actually a good approach! That’s the old “poke and see what changes” approach. Not very scientific, but often very effective. Sometimes the circuit just needs to be gently prodded to reveal the fault.
