electronics workflow

the practical process for building electronics projects, learned at a neurotech startup.

the build sequence

1. breadboard — get the circuit working at all. ugly is fine.
2. get it to work — functional prototype, doesn't matter how messy
3. make wiring nice — clean up connections, organize
4. make UX nice — put it in a box, hot glue, add controls

this mirrors the general principle from software-workflow: make it work, then make it good. resist the urge to make it pretty before it's functional.

fundamentals

• power sources: DC, understanding volts
• signals: what's being sent where
• PWM for control: pulse width modulation to manage output
• program microcontroller → flash code

practical lessons

jumper cables are worthless — use proper breadboard connections. this sounds minor but bad connections cause hours of debugging phantom issues. always ensure robustness (see intentionality).

the demo matters

having a pretty cool thing to show off and demo is very powerful. even a rough breadboard prototype gets people excited and provides feedback. see critical-path — the demo is often on the critical path even when polish isn't.
