Finding the Exact 8:1 Gear Ratio The starting point of this project was figuring out how to achieve an exact 8:1 gear ratio with the capstan drives. In my capstan drive video, I designed all the drives to have an 8:1 gear ratio—but when measured, none of them actually did. The commenters on that video pretty accurately diagnosed my mistake. I had made the outer diameter of the big drum 8 times larger than the outer diameter of the small drum, but this doesn't account for the diameter of the rop

Is This the End of Google As We Know It?

gizmodo.com Luc Olinga 2026-01-05 15:19:53

OpenAI CEO Sam Altman arrived in Washington this week with a carefully crafted message for policymakers: Artificial intelligence is already boosting productivity for millions of Americans, and his company intends to keep it “democratic” by putting it in everyone’s hands. As the capital buzzes with debates over AI regulation, Altman is positioning OpenAI not as a disruptor to be feared, but as an engine for universal progress. “It’s not about stopping disruption, but putting it into people’s han

Tesla reports sales miss as auto revenue drops for second straight quarter

cnbc.com Lora Kolodny 2026-01-05 20:50:59

Elon Musk, CEO of SpaceX and Tesla, attends the Viva Technology conference at the Porte de Versailles exhibition center in Paris on June 16, 2023. Tesla's slump this year is partly due to a backlash against the company in the U.S. and Europe, after CEO Elon Musk spent heavily to help reelect President Donald Trump , endorsed Germany's extreme anti-immigrant AfD party, and then led the Trump administration's Department of Government Efficiency. At DOGE, Musk helped to slash the federal workforce

Tesla profits pulled down by falling EV sales and regulatory credits

techcrunch.com Kirsten Korosec 2026-01-05 20:48:04

Falling EV sales combined with a lower average selling price, less revenue from regulatory credits, and a decline in solar and energy storage revenue took a toll on Tesla’s bottom line during the second quarter of 2025. And a 17% growth in revenue in its services business, which includes cash generated from its Supercharging network, wasn’t enough to close the gap. The company reported Wednesday revenue of $22.5 billion, a 12% decline from the same period last year. The company’s second quarter
