Retrofits Done Right: Physical Controls for Heated Seats

1 Share
Heated Seat controls

We’ve all owned something where one tiny detail drives us nuts: a blinding power LED, buttons in the wrong order, or a beep that could wake the dead. This beautifully documented project fixes exactly that kind of annoyance, only this time it’s the climate-controlled seats in a 2020 Ram 1500.

[projectsinmotion] wasn’t satisfied with adjusting seat heating and ventilation only through the truck’s touchscreen. Instead, they added real physical buttons that feel just like factory equipment. The challenge? Modern vehicles control seats through the Body Control Module (BCM) over a mix of CAN and LIN buses. To pull this off, they used an ESP32-S3 board with both CAN and LIN transceivers that sits in the middle and translates button presses into the exact messages the BCM expects.

The ESP32 also listens to the CAN bus so the new physical buttons always match whatever setting was last chosen on the touchscreen, no mismatched states, no surprises. On the mechanical side, there are 3D-printed button bezels that snap into blank switch plates that come out looking completely stock, plus a tidy enclosure for the ESP32 board itself. Wiring is fully reversible: custom adapters plug straight into the factory harness. Every pinout, every connector, and every wire color is documented with WireVis diagrams we’ve covered before, making this an easily repeatable seat-hack should you have a similar vehicle. Big thanks to [Tim] for the tip! Be sure to check out some of our other car hacks turning a mass produced item into one of a kind.

Trump admin axed 383 active clinical trials, dumping over 74K participants

1 Share

When the Trump administration brutally cut federal funding for biomedical research earlier this year, at least 383 clinical trials that were already in progress were abruptly canceled, cutting off over 74,000 trial participants from their experimental treatments, monitoring, or follow-ups, according to a study published today in JAMA Internal Medicine.

The study, led by researchers at Harvard, fills a knowledge gap of how the Trump administration’s research funding cuts affected clinical trials specifically. It makes clear not just the wastefulness and inefficiency of the cuts but also the deep ethical violations, JAMA Internal Medicine editors wrote in an accompanying editor’s note.

In March, the National Institutes of Health, under the control of the Trump administration, announced that it would cancel $1.8 billion in grant funding that wasn’t aligned with the administration’s priorities. The Harvard researchers, led by health care policy expert Anupam Jena, used an NIH database and a federal accountability tracking tool to find grants supporting clinical trials that were active as of February 28 but had been terminated by August 15.

Self-assembling data centers in space are becoming reality as Rendezvous Robotics partners with Starcloud — Elon Musk chimes in that 'SpaceX will be doing this'

1 Comment
Rendezvous Robotics' autonomous tile-based modules, built using Project TESSERAE tech, will potentially power Starcloud's plans to build massive data centers in space. The company is partnering with Nvidia to build a 5-gigawatt facility in orbit, and Rendezvous can help make that distant future a reality.

Westinghouse is claiming a nuclear deal would see $80B of new reactors

1 Comment

On Tuesday, Westinghouse announced that it had reached an agreement with the Trump administration that would purportedly see $80 billion of new nuclear reactors built in the US. And the government indicated that it had finalized plans for a collaboration of GE Vernova and Hitachi to build additional reactors. Unfortunately, there are roughly zero details about the deal at the moment.

The agreements were apparently negotiated during President Trump’s trip to Japan. An announcement of those agreements indicates that “Japan and various Japanese companies” would invest “up to” $332 billion for energy infrastructure. This specifically mentioned Westinghouse, GE Vernova, and Hitachi. This promises the construction of both large AP1000 reactors and small modular nuclear reactors. The announcement then goes on to indicate that many other companies would also get a slice of that “up to $332 billion,” many for basic grid infrastructure.

So the total amount devoted to nuclear reactors is not specified in the announcement or anywhere else. As of the publication time, the Department of Energy has no information on the deal; Hitachi, GE Vernova, and the Hitachi/GE Vernova collaboration websites are also silent on it.

In 2022, the world axed a disease name seen as racist. US just switched back.

1 Comment

Without explanation, the US Centers for Disease Control and Prevention under the Trump administration has reverted from using the disease name "mpox" to the obsolete "monkeypox," which the world abandoned in 2022 because it was seen as racist and stigmatizing.

Mpox is the name of the disease caused by Orthopoxvirus monkeypox, a relative of smallpox and cowpox that has exploded to global prominence in recent years. In 2022 and 2024, the spread of mpox caused the World Health Organization to declare international public health emergencies.

Amid the attention, health officials became acutely aware of the problematic name.

OpenAI and Nvidia’s $100B AI plan will require power equal to 10 nuclear reactors

1 Comment

On Monday, OpenAI and Nvidia jointly announced a letter of intent for a strategic partnership to deploy at least 10 gigawatts of Nvidia systems for OpenAI's AI infrastructure, with Nvidia planning to invest up to $100 billion as the systems roll out. The companies said the first gigawatt of Nvidia systems will come online in the second half of 2026 using Nvidia's Vera Rubin platform.

"Everything starts with compute," said Sam Altman, CEO of OpenAI, in the announcement. "Compute infrastructure will be the basis for the economy of the future, and we will utilize what we're building with NVIDIA to both create new AI breakthroughs and empower people and businesses with them at scale."

The 10-gigawatt project represents an astoundingly ambitious and as-yet-unproven scale for AI infrastructure. Nvidia CEO Jensen Huang told CNBC that the planned 10 gigawatts equals the power consumption of between 4 million and 5 million graphics processing units, which matches the company's total GPU shipments for this year and doubles last year's volume. "This is a giant project," Huang said in an interview alongside Altman and OpenAI President Greg Brockman.
