Humble 3d Print Farmer

Doing a run on the second side of the same PCB for a full 15 min this time. I really need a smoother way to apply the solder mask...

You should work hard to minimize the number of external software libraries that you depend on as quickly as possible Certain things you won’t be able to get around, ie the kernel or sqlite, but random npm packages should mostly be eliminated in favor of inhouse replacements

All militaries that are not based around masses of cheap drones are obsolete as of right now.

Your ground beef costs nearly 20% more than a year ago because US cattle herds hit a 75-year low and ranchers can’t find workers. A New Zealand dairy farm kid convinced Peter Thiel that GPS cow collars are the fix. Thiel just valued the company at $2 billion. The company is Halter. Craig Piggott grew up watching his parents work 100-hour weeks on dairy farms in New Zealand’s Waikato region. He barely scraped into engineering school (scored 254 points, needed 250), landed at Rocket Lab, then quit before their first rocket launch to build smart collars for cows. He was 22. The tech sounds ridiculous until you see the numbers. Each solar-powered collar collects 6,000 data points per minute on location, health, fertility, and grazing patterns. Farmers draw virtual fences on a phone app. Cows learn to respond to sound and vibration cues within 7 to 10 days, moving between pastures without a single physical fence post. Halter’s US customers have created 11,000 miles of virtual fencing so far, roughly the perimeter of the continental United States, saving an estimated $220 million in fencing costs. Physical fencing runs about $20,000 per mile to install and maintain. The timing is what makes this a $2 billion company and not a $200 million one. The US cattle industry generates over $1 trillion a year but it’s cracking. The USDA counted 27.6 million beef cows as of January 2026, still declining. Fifteen thousand American farms vanished in 2025. Over half of US ranchers are older than 55. The labor crunch has only gotten worse under tighter immigration enforcement. This month, 3,800 workers walked off the job at a JBS plant in Colorado (one of the country’s biggest beef processors). Cattle slaughter is down 10% year over year. Founders Fund actually first invested in Halter’s $7 million Series A back in 2018. They’re not showing up late. The valuation doubled from $1 billion to $2 billion in nine months. Icehouse Ventures, one of Halter’s earliest backers, put in $100,000 at the seed stage. Their total stake is now worth $409 million. The fund’s CEO told the New Zealand Herald today that at Halter’s current growth rate, it will surpass Fonterra (New Zealand’s $5.9 billion dairy cooperative) in value within 11 quarters. 600,000 cattle are wearing Halter collars across three countries. The “cowgorithm” is a real, trademarked AI algorithm that trains each animal individually. Ranchers report saving 20 to 40 hours a week. And the kid who barely got into college was just named New Zealand’s Innovator of the Year.
