  • This seems very similar to the OG all recipies website. Most of their website isn’t that bad still. They also support creating an account to save and organize recipies.

    I do not understand the fragmentation of the modern web.

    Want to send money to a friend? Zelle, Venmo, Cash App, PayPal, Google pay, Apple cash, Popmoney, etc. There’s also the growing swath of messaging apps that support peer to peer payment.

    Want to buy some second hand clothing? There’s Poshmark, Offer Up, Thread Up, Depop, Vinted, Etsy, Grailed, the RealReal, Craigslist, eBay, Facebook Market Place, etc. This is on top of the usual retailers who are also establishing an online presence like Plato’s closet, goodwill, etc.

    Rinse and repeat for basically any category possible. I’m running into consumer fatigue and I can’t imagine it’s better for sellers.






  • This is pretty cool.

    This is the how-they-done-it paragraph. Essentially, they printed mechanical logic gates by taking advantage of a conductive filament that grows/shrinks as it heats and cools. Cool!

    The conductive filament the researchers used is Electrifi by Multi3D, which is PLA combined with copper micro-particles. A segment printed in this filament is normally very conductive due to the densely-packed particles, but as temperature increases (beginning around 40° C) the polymer begins to soften and undergoes thermal expansion. This expansion separates the copper particles, causing a dramatic increase in electrical resistance as electrical pathways are disrupted. That’s pretty neat, but what really ties it together is that this behavior is self-resetting, and reversible. As long as the PLA isn’t straight up melted (that is to say, avoids going over about 150° C) then as the material cools it contracts and restores the conductive pathways to their original low-resistance state. Neat!


  • I bought a 12 in December when they were on sale due to the looming 13 launch. The stock OS is pretty good and the hardware is well speced. I came from a Pixel 3a and have owned a number of pixel and Nexus phones over the years.

    It’s a bit large physically, which can present some challenges with pockets and single handed operation. It’s roughly the same size as an iPhone pro max for a size reference.

    The rounded screen can be love/hate for some. If your son is prone to dropping things, it might be worth looking at a phone with more traditional bezels. Even the more protective cases have lower sides on the two long edges of the screen to let your finger reach the edges of the display.

    As for the brand, they are pretty popular globally, but their availability locally really depends on where you live. In the US, you used to be able to buy them in T-Mobile stores, but that stopped a while ago. I don’t know of any brick and mortar stores that you can walk into and pick one up, although Best Buy does have them in their local warehouses and can get you one somewhat quickly.



  • You got a lot of replies on the modeling side of things. It’s not clear if you have a printer, so let me quickly hit on that.

    There are a bunch of different 3D printing services you can use to print things, including local (at your library potentially or a maker space) as well as commercial.

    3D printera fall into big buckets:

    • melt the material as you go. The most common version is FDM. FDM printers can make somewhat fine detailed prints, but their forte is making larger things with larger details
    • deposit a layer of material and fuse it via light. This can be done with a powered material and a laser (SLS) or a liquid resin and a light source (SLA). This method produces much higher detailed prints, but has a bigger barrier to entry. SLS printers are expensive, but can produce large and very durable prints. SLA printers have affordable home versions, but their build volume is somewhat small, their parts will require post processing to finish (rinsing, during), and you will have to deal with responsible disposal of the used resins and solvents. Resin prints are hard, but can be a bit brittle

    If you’re going to be purchasing the prints, I would go SLS. You’ll get fine details and the parts can be nylon (or even metal) so they’ll be durable.

    If you’re printing at home, SLA is probably the way to go.






  • If you’re looking for an outlet, why not project shop with the aim of making something?

    This gives you the opportunity geek out on the gadgets you’ll need to pull off whatever you want to make. More importantly, the journey will continue post purchase as chase the thing you want to make.

    You can make both digital and physical stuff. With things like CAD, Arduino/Raspberry PI, and IoT you can also blend the two pretty easily.

    A very low key example might be a small garden. I’ve put a bit of time/effort into my seed stating setup, including designing and printing parts for my lighting rig. It seems like the setup iterates a bit every year. In addition, every year I spend a decent amount of time thinking about what I want to grow this year and then diving seed catalogues to find some new-to-me verity of something I’ve grown before.

    You can also design from-scratch speakers and go as far down that rabbit hole as you want to - buy vs build (kit) vs design the amplifier, ditto for the actual speaker, etc.
