Show HN: iFixit created a new USB-C, repairable soldering system (🔥 Score: 165+ in 1 hour)

Comments: https://readhacker.news/c/6esqR
After years of making screwdrivers and teaching people to repair electronics, we just made our first electronic tool. It's been a journey for us to build while hewing to our repairable principles. We're really excited about it.
It's a USB-C powered soldering iron and smart battery power hub. Super repairable, of course. Our goal is to make soldering so easy everyone can do it:
https://www.ifixit.com/fixhub
We didn’t want to make just another iron, so we spent years sweating the details and crafting something that met our exacting standards. This is a high-performance iron: it can output 100W of heat, gets to soldering temperature in under 5 seconds, and automatically cools off when you set it down. The accelerometer detects when you pick it up and heats it back up. Keeping the iron at a lower temperature while you’re not soldering shouold prolong the life of the tip.
What’s the difference between this iron and other USB-C irons on the market? Here’s a quick list:
Higher power (our Smart Iron is 100W, competitors max out at 60W over USB-C, 88W over DC Supply)
Heat-resistant storage cap (you just have to try this out, it’s a real game changer in day-to-day use)
Polished user experience
A warranty and a local company to talk to (I can’t find any contact information for Miniware)
Comfier / more natural grip
Shorter soldering tip length
No-tangle, heat-resistant cable
Locking ring on the cable, so it can’t snag and get disconnected (this happens to me all the time on other irons)
More intuitive settings, either on the Power Station or on the computer
We used [Web Serial](https://caniuse.com/web-serial) for the interface, which is only supported in Chromium browsers. The biggest bummer with that is that no mobile browsers support it, yet. Hopefully that changes soon.
Hardware is hard! It's been a journey for us. Happy to answer any questions about how we made it.

Show HN: Tune LLaMa3.1 on Google Cloud TPUs (Score: 150+ in 19 hours)

Comments: https://readhacker.news/c/6epig
Hey HN, we wanted to share our repo where we fine-tuned Llama 3.1 on Google TPUs. We’re building AI infra to fine-tune and serve LLMs on non-NVIDIA GPUs (TPUs, Trainium, AMD GPUs).
The problem: Right now, 90% of LLM workloads run on NVIDIA GPUs, but there are equally powerful and more cost-effective alternatives out there. For example, training and serving Llama 3.1 on Google TPUs is about 30% cheaper than NVIDIA GPUs.
But developer tooling for non-NVIDIA chipsets is lacking. We felt this pain ourselves. We initially tried using PyTorch XLA to train Llama 3.1 on TPUs, but it was rough: xla integration with pytorch is clunky, missing libraries (bitsandbytes didn't work), and cryptic HuggingFace errors.
We then took a different route and translated Llama 3.1 from PyTorch to JAX. Now, it’s running smoothly on TPUs! We still have challenges ahead, there is no good LoRA library in JAX, but this feels like the right path forward.
Here's a demo (https://dub.sh/felafax-demo) of our managed solution.
Would love your thoughts on our repo and vision as we keep chugging along!
