The article discusses achieving stable NTP server performance on a Raspberry Pi by addressing thermal-induced timing jitter. By isolating CPU cores and implementing PID-controlled thermal stabilization, the author reduced frequency variability by 81% and frequency standard deviation by 77%. The solution involved dedicating a CPU core to timing tasks, maintaining a constant CPU temperature, and using a PID controller to stabilize the crystal oscillator's frequency. The improvements led to a significant reduction in RMS offset and frequency drift, enhancing time accuracy. The article provides detailed setup instructions and considerations for replicating the optimized system.

Tiny Mac look-a-like alarm clock transformed to run real Mac software

A vintage tech enthusiast transformed a miniature Mac-like desk toy alarm clock into a functioning computer running real Mac software. The project, dubbed 'WonderMac,' involved fitting a Raspberry Pi Zero W and a 2.8-inch touchscreen into the alarm clock chassis. The TechTuber faced challenges like cracking the case, installing software, and repurposing the USB-C input for power. Despite minor issues, the project was successful, though it cost around $100. Detailed project essentials and software resources have been shared for those interested in replicating the mini Mac project.
