Anybody aiming at colonizing Mars should realize that the Earth's oceans are • Easier to reach • Easier to colonize • More fertile Oh, and there's nearly 3x land in the Earth's oceans (140M sqm) than in all of Mars (56M sqm)

In instant coffee production they get a yield of 35% by weight of the roasted beans! This is achieved in an acidic environment. They then neutralize it to make it drinkable! patents.google.com/patent/US36441… This patent wants to treat it with alkali to make liquid coffee darker James Hoffmann

Excited to launch EmailGPT - simply fwd long emails or PDF attachments to [email protected] and get a bullet point summary. Pro-Tip: works great for summarising all the substacks that you have been meaning to read.

Today's hyperfocus brought to you by the Beacon "eddy current surface scanner", a 3d printer bed probe that quickly scans the surface instead of slowly poking it. If you look at the photo below, you'll notice they blurred out the ICs. This annoyed me.

i'll never get over how the cochlea is an analog fourier transform organ

To use the Montreal subway, you tap a paper ticket against the turnstile and it opens. But how does it work? And how can the ticket be so cheap that it's disposable? I opened up the tiny NFC chip inside to find out more... 1/15

What if you could fine tune your labels and see the print layout in real time? 🤓

Hey geeks! To bring AI into the last 100 meters of daily life, we're launching the CH570—a RISC-V 32-bit SoC with 2.4GHz wireless and USB 2.0(Host&Device). It’s an upgrade from the CH32V003, with more features at the same low price—still just about a dime(10 cents).

New capacitor de-rating chart project dropped.

I met an EDA guy on a plane who had a working datasheet-to-symbol tool, thought I'd share IC Lib auto-finds the pinout diagram in a datasheet, you select and extract the pins, then fix any mistakes + export. Great life

This occurred to us! We CT scanned an espresso puck that was just tamped without distribution (left) and one that was prepared with WDT (right). The red dots are microscopic voids in the pucks. The non-distributed puck is about 2% void by volume, and the WDT puck is 0.25% void.
