If these could be rented it could be interesting for occasional road trips instead of e.g. renting a whole car. It could also see something like this but using one of the very high energy density but non (in-situ) rechargable battery chemis

Any idea why they would use brushed motors? When every gram counts I would think ditching the mechanical commutator would be a no-brainer, but maybe adding another leg to the H-bridge is a bigger penalty?

I saw a video claiming that Germanic words beginning with sn- all have to do with the nose. For example “snoop”, “snob”, “sniff”, “snarl”.

How robust are these to random floating logs? They’re quite common here in the Salish Sea and have been cited as the reason that the Boeing hydrofoil project never really took off.

I have to wonder if at some point rich eccentrics will start installing CO2 scrubbers in their houses to bring the indoor concentration below 400 ppm.

My guess is that the name is from the Preston character in the 1995 Wallace and Gromit short A Close Shave, which would have premiered a couple of months before the first beta.

I feel like this is a lot more approachable with the advent of cheap mass-produced RC helicopter parts (modulating the collective pitch with the audio waveform). (Which has me wondering if you could do some fun directional things with the s

Only loosely related, but are there any affordable non-invasive tests for past lead exposure? I have a cluster of symptoms that are consistent with lead exposure[1], along with a lot of past activities involving lead (stained glass, old-sch

A few years back spent a lot of time stripping lead paint using a heat gun and IR emitter thing ("silent paint remover"). It was definitely smelly, but I convinced myself that the temperatures were far too low to vaporize lead. Bu

As a sanity check I looked at it from the standpoint of a 2400-calorie diet of 100% carbs (glucose) and it works out to around 32 grams per hour of CO2, which agrees with a figure of around 1000 liters per minute to dilute it down to 400 pp

This may or may not apply to OPs app, but for mobile-first apps with a broad audience, having an identical appearance/interaction model across competing mobile platforms is a bug, not a feature. Or maybe not exactly a "bug" b

Kind of obsolete now but a radio tuner where the strength of the detent is proportional to the strength of the signal.

There's actually a clever way to reconfigure the inverter electronics and (induction) motor to essentially do "regenerative braking" off of a 3-phase supply ( https://patents.google.com/patent/US5341075A&#

Not directly related, but a fun(?) anecdote: I worked for a dog-friendly company in Seattle for a few years in the mid 20-teens. I started out commuting from my parents' place (who dog-sat for me), taking a commuter train and then a bu

Step 0 in the US might be enforcing laws against fake temporary tags or concealed license plates. If I had a dollar for every “thin blue line” sticker-sporting car with a barely-transparent bit of plastic over the license plate… Seems like

I think it's all about the possibility to later upsell. I don't think the economics work out where it's cheaper to install something like a seat heater in every car and permanently disable for price discrimination purposes (t

If done right the stations will be in locations where having a car is more of a liability than a convenience (i.e. downtowns with lots of traffic and expensive parking).

We need “anything sketchy about this 20-page contract” as a service (for something less than the cost of retaining a lawyer).

To be fair, that's about the same with the exchange rate, but the fact that the average mortgage cost across all of Canada is the same as one of the most expensive US markets is telling.

About two tablespoons of store-bought ranch dressing will put you at the 2% number that the article suggests as the high end of preindustrial intake. (11g of unsaturated fat in 2 tablespoons of Hidden Valley Ranch, assume soybean oil becaus

I find a reversal test is sometimes useful when considering whether to keep something: if I didn’t already own it, would I buy it for an amount that it might sell it for.

I’ve been digging into Apple’s (existing) accessibility features last week and it made me think about what (for lack of a better term) an “accessibility first” app architecture might look like. Current app UIs are all about how to visually

It’s also denser than water and somewhat hydrophobic so if I understand correctly it tends to settle at the bottom of aquifers.

The "Automatically hide and show the menubar" setting should really default to "Never" for notched displays, since it doesn't actually gain you any extra real-estate and just slows you down with a pointless animatio

A recent HN post mentioned that a signal like radar from a nearby airport can sometimes be enough to kick the keyless sensor module out of sleep mode and drain the battery. (This was the one about CAN injection attacks).

Anhydrous ammonia’s volatility is on the order of that of propane/LPG (although a lot more hazardous to inhale), so the containment is easier than what the words “pressure vessel” might evoke.
