The iteration cycles are limited necessarily by the time between tapeout and getting chips off the line to a testable state. Maybe there's a little room to get an in-wafer test probe system built at the fab if each die has a standard p

I would love a simpler system. Everything is pointing me back towards using a Windows server eval instance for this, which feels like a pretty heavy way to manage a bunch of alpine containers. FreeIPA, openLDAP and I think the other one I t

What an amazing tool: it loads and displays the kicad native files in a simple web browser, but moreover - you don't have to be the intermediary, cloning some repo and then uploading the individual files to a website. I wish that exist

How'd that work out for SawStop? A tech that makes table saws basically safe by stopping the blade immediately on contact with water (simplified description). The inventory tried to license the tech, then tried to get regulatory agenci

Article is very interesting and focuses on the historic faces of DARPA, not really getting too much into the modern state of the agency. Over the past 10+ years DARPA have embraced the OTA - other transaction authority - as a contract vehic

As a pilot, I love the idea. But as soon as I saw the cockpit I knew the price would be out of my league. I'm still in the single digit gallons per hour world, and this bad boy is running at 50-60 gallons per hour. Nice engine. Would b

For me (and I imagine a lot of people) it is his Fallingwater house ( https://fallingwater.org/ ) which is a tremendous example of architecture which builds on its environment. I don't think that's a particularly gr

The other answer about magnetostriction is technically correct (the best kind) but Misses the actual cause, which is subharmonic oscillation. This occurs when you have not stabilized your control loop properly and is often the result of ina

Looks like it uses yahoo_finance_api in rust. In theory that supports options, but no idea whether this tool handles that data properly, I didn't feel like searching that hard. It's gonna take a lot to pry me away from my spreadsh

Website was not pleasant to use on mobile, I couldn't really see much, and the demo was definitely not mobile friendly. At least on a pixel 6. I like the idea. I take it as an all in one lab notebook for electronics. You might consider

Interesting that all but two of the listed startups were software companies (FedEx, Tesla). I imagine the costs of fixed investments required to scale a company not based on software can reduce the potential max returns quite substantially.

> try to get by on a two-minute shower once a day This is pretty typical aboard ship for smaller vessels on long voyages. Not so hard as it sounds: get wet, turn off; lather up, rinse off, turn off. You can do with 20-30 seconds of water

Yes, this bothered me too. It's impressive how much energy is required to just melt water much less bring it to temperature. It's 330 kJ/kg, which is 1250 kJ/gallon: 350 Wh. So it costs more energy to defrost one gallon

I can't deal with dates unless they include day of week. I wrote a very simple script (basically a regex) to add a letter indicating the day. Also fun for changing website themes, extracting streams to files, augmenting games. Violentm

Around early 2019 I set up a raspberry pi 3 running Raspbian. I made the /var/log partition a ramdisk. Haven't touched it since. It goes down for power outages but probably has been out for a couple minutes total over five ye

There are a number of conformal coatings that can be used to keep a circuit board dry at fish tank pressures. Parylene is my favorite as it isn't too harsh on the board materials and coats even underneath the surface mount components.

You'd want a quote if you're spending that kind of money: https://www.voxa.co/solutions/mochii/faqs How much does one unit cost? Mochii starts at $48K for the imaging only unit. The spectroscopy-enabled

In the US so health insurance and PTO, then 401k. Hate unlimited vacation, I like owning my time off. I'm a hardware engineer so remote work isn't very important for me. I don't really want a full lab at my home. Other things

Yes, it can be that hot; I cuddled nude with a TLAM in the Carribbean to stay cool. I think UK boats were built for colder waters; the ventilation couldn't keep up on the deck in the shallow, warm waters. Things are certainly not made

While true, confidential restricted is not a US classification marking. It sounds more like the language on a clickwrap license installer, like what you would get for the radio programming software. This sounds like not much. It would allow

Depends on your bracket I suppose. According to this [0], an individual $180k salary in AUS is taxed at about $58k. In USD would be about $44k. But... I pay $12k in health insurance, so they're reasonably close. I think AUD < USD th

Well, if you're asking for opinions, I'll offer a few. I certainly appreciate having another option for focused tech aggregation, especially if the comments section is able to attract and retain high quality, well-informed comment

As an EE I love the idea of open firmware. I wish more companies would provide it - akin to the old TVs and other equipment that came with [full!] schematics inside. It would let me truly understand and modify the items that I purchased. Th

Once you start thinking with "kilo"bytes in the denominator, you're in the wrong ballpark. There are tons of applications for remote insitu sensors which don't send much data, or often. Game cameras, equipment trackers,

Been using one of the Analog demo boards, I think one of the ADIN1100 parts which is 10BASE-T1L instead, to solve a problem that occurred when I let a mechanical engineer order a cable for me. No twisted pair inside. Ethernet on either end.

It's not. But at the margin it is. If you already have a touch screen display then adding a button costs next to nothing on a per car basis. And there are a ton of solenoids in cars so they can probably reuse one and save the cost of t
