mcfudge Onemissing part and one missing trace. My kit (Feb 2019) was missing one trace from LED D8 cathode side up to resistor R2 (same side). Connecting those will enable the power on LED to illuminate. The missing component was R17. I powered it on and when it didn't work I discovered 3 pins on the STC 89C52 were not connected. After firmly soldering it still did not work and the IC began to overheat. I'll get a replacement and give it a go again. I do expect the circuit to fully work as a clock and/or timer. I don't think it's just an exercise in practicing soldering components that ultimately do nothing.
