About the Legacy Power Board

Legacy Power Board is an open source PCB design by Hongcheng-Gao, published on GitHub under the MIT license. It is a 2-layer board, with 5 components from 5 distinct parts.

Other key parts include the 74LS04. By type, the board carries 1 IC, 1 transistor, 1 diode, 1 capacitor and 1 resistor.

From the project

Engiworld: What Can Frontier Agents Deliver in Professional Engineering Environments?

The 1,301 tasks use a common directory layout:

Software names are lowercase, without version numbers. Multiple names are joined with --. Open-Environment Engineering tasks use cli/agent-selected/. Interface folders contain only the modes available in that category.

Each task contains a task-.json definition, initfile/ inputs, and its evaluator (eval.py, with groundtruth/ where required). IDs use --------; operating systems retain ubuntu or windows from the task. Reverse-modeling tasks retain a -reverse` suffix on the task number to distinguish them from same-numbered tasks.
