Daily Hardware Design Challenge

Every day we publish one fresh hardware engineering design challenge covering analog circuits, digital logic, power electronics, signal integrity, and embedded systems. Answer in your own words, get instant AI feedback graded against a model answer, and see how you rank on the daily leaderboard.

One new challenge every day

Challenges rotate through the topics that hardware interviews actually test: op-amp and filter design, MOSFET and BJT biasing, transmission lines and termination, clocking and metastability, DC-DC converter topologies, thermal design, and debug scenarios from real bring-up work.

Instant AI grading with a model answer

Your response is scored from 0 to 100 percent against a reference solution written by practicing hardware engineers. Calculation questions are checked numerically with unit conversion, so 16 mA and 0.016 A are treated the same. You always see the model answer after submitting.

Free for every registered engineer

The daily challenge is free. Create an account, submit your answer, and your score is logged to your dashboard and the daily leaderboard so you can track progress over weeks of practice.
