doug_life··on Formlabs Studio 1 $699 Resin Printer
This printer at least comes with the "Open Material Mode (included)" that lets you print with 3rd party resins. I'm sure the workflow won't be quite as nice as with the Formlabs native resin. That is unless you can somehow refill the old jugs or buy empty ones. Before long I imagine 3rd party compatible containers will show up.

Agreed, unless you need to print intricate 3D figurines or high resolution engineering widgets, get a FDM printer and avoid the mess of SLA.

You can wash manually with some isopropyl alcohol in a wash basin and then cure in the sun. It will be a pain to do, and somewhat inconsistent, but its possible. You can also get a cheaper wash and cure station for other 3D printers that would likely work well enough with some tuning.

Thanks. I’ve been looking for a clean ots solution and somehow managed to not come across your company yet. Just purchased pre-assembled module!

doug_life··on Stardew Valley developer made a $125k donation to the FOSS C# framework MonoGame
“In Feb. 2024, Stardew Valley reached 30 million copies sold, and if we assume each copy sold for $15, that means that the game could have generated a revenue of $450 million. A modest 10 percent profit margin puts ConcernedApe’s earnings at $45 million, a number that is likely to increase in the future.” Source: https://dotesports.com/stardew-valley/news/how-much-money-di...

doug_life··on Reverse engineering a 27MHz RC toy communication using RTL SDR
It is likely that that the sub had it's antenna tuned to work well in water while the RC car antenna was tuned for open air. The two different mediums will change the antenna impedance.

Any idea why this would not be compatible with Vivaldi 7.5.3735.66? The store says "This item is not compatible with your current Chrome version"

Should we also stop adding iodide to salt or fortifying white bread? I see your point, but society has benefited as a whole by forcing some of these substances onto populations. I think it's fairly evident that many humans in the US are either unable or unwilling to really care about their health.

This may be obvious to most here, but you need Node.js installed for the MCP server to run. This critical detail is not in the set up instructions.

https://speechpulse.com does fully local audio transcription. The UI and settings are not the most intuitive, but it works fairly well and they are making constant updates.
doug_life··on Ohm: A user-friendly parsing toolkit for JavaScript and TypeScript
Side note, I really wish software would stop using EE terminology to name things. Ohm, Capacitor, Electron, etc. It muddies up search results for no good reason. Is there a reason this has become a trend lately?
doug_life··on VSCode Marketplace Web Pages No Longer Allow Direct VSIX Downloads
Unfortunately its not a mirror. Some extensions have licensing issues that prevent them from being on open-vsx. For example PlatformIO. I ran into this issue earlier this week when trying to set up Windsurf which uses open-vsx.

Are there any equivalents that work in Windows 11? There were a handful that worked in previous versions of Windows but lots of them won't work in W11 and those that say they do are risky installs.

Hoarder is an option you can self host and has most of the same features as this tool plus more. The AI tagging feature and full page indexing is pretty handy. Hoarder.app

https://github.com/McCloudS/subgen worked very well for me. I had a TV series where somehow the last few seasons timestamps did not match up with subtitle files I could find online. I used subgen and it worked surprisingly well.

Somewhat related is the The Rock-afire Explosion band from ShowBiz Pizza Place. There is an excellent documentary on the history and some of the fans preserving the technology. https://www.youtube.com/watch?v=gTmhS6hcY-A

Very cool to see how it all came together. Can you elaborate on why you chose to use a Kalman filter in your signal chain?
doug_life··on Beginners guide to building a hardware hacking lab
I am a fan of the grey market Fluke 17B+. You get many of the features of the high end Flukes like the 87V without the high cost. They are my go to for non critical lab measurements.

8uA is still large compared to some other options. I work on medical implants that average 15uA while actively sensing biological signals 24hr/day. This includes the analog front end hardware to condition the signals as well. 8uA of deep sleep current would be a non starter.
doug_life··on Apple’s new Transformer-powered predictive text model
The thing I find most interning is that typing (in English) on the microscopic Apple Watch keyboard seems to have better results than typing on my phone keyboard. I don’t know what the watch keyboard does differently but it seems to read my brain while my phone does the opposite.
doug_life··on Ask HN: Whatever happened to the “coming wave” of delivery drones?
I live in a Durham, NC and there is a small radius where a company called Flytrex does drone food delivery. We use it every couple weeks since they have almost no fees unlike Uber Eats. From what I understand they place the order, drive a car to pick up your food, drive back to the launch pad, then load and send the drone. It then drops the food using a long cable that leaves behind a reusable bag in your front lawn. It’s surprisingly accurate since it has about a 15ft diameter circle to hit in my front yard to avoid trees and the house. The one downside is the weight limit and weather. If you go over something like 8 pounds then the drone will fly what it can and someone will follow begging in a car with the remainder. Bad weather means car delivery.

"So both “Bernoulli” and “Newton” are correct. Integrating the effects of either the pressure or the velocity determines the aerodynamic force on an object."

Oh, so this isn’t full in circuit debugging like ESP-PROG would enable, correct? These parts just have built in USB-Serial for programming and printing to the terminal without an external IC.

Edit: Never mind, it does appear to allow full in circuit debugging. I’ll have to do some more research.
