via the RSGB: Schoolboy makes silicon chips at home

We normally think of silicon chip fabrication as being a cutting-edge practice, requiring huge investments and hundreds of people. However, we learned recently of Sam Zeloof, a 17-year-old high school student in the USA, who is making his own chips in his garage.

via HACKADAY: Ask Hackaday: Is Your Clock Tied to Mains Frequency?

Earlier in March we heard about a quirk of the interconnected continental European electricity grid which caused clocks to lose about six minutes so far this year. This was due to a slight dip in the mains frequency. That dip didn’t put anything out of commission, but clocks that are designed to accumulate the total zero-crossings of […]
