The webpage linked is an example of everything I wish people would stop doing in web design.

Fortunately, at the bottom there is a link to the "technical documentation" (https://squeezlabs.github.io/handcrank/) which is vastly improved (aside from being light-mode-only and linked from a dark-mode-only marketing page). It also gives me much more interesting information (specifically: models that can apparently run acceptably on a Pi 5).

Please let me read your content with a scrollbar that works the way scroll bars are supposed to, rather than turning everything into a weird slide show where you don't actually know when the next slide is coming. Please let me just click on buttons that look like links to more information, without JavaScript.

Why can't technical people appreciate that us, the silent majority, love having our scroll hijacked? I can't remember the last time I used a scroll bar to navigate a website, but using it to navigate between choppy javascript keyframes fills me with joy.

This isn’t scroll hijacking

You can scroll normally, with all your favorite keys, or go super fast to the bottom

It’s just scroll animations. Bad ones, admittedly.

Comment by mrandish 1 day ago

> just scroll animations. Bad ones

Scroll animations, post-grid floating voids, bouncy house dampening, hyper rounded... everything. These are the 50s Chevy fins of today.

I've enjoyed working with some great designers over the years, Stanford D-School and even wild-raised. All the good ones intuitively steered clear of trends destined to be era-stamp tropes. They'd say, "I can already hear the ghosts of design-future mocking me: 'That's so early-AI' and 'Yo, the mid-20s called and wants their bento grid back.'"

Not even an ADB-to-USB dongle?

Comment by ProllyInfamous 21 hours ago

Thirty years ago, Apple made a translucent green ADB "keypad" which had a small LCD display (perhaps only two lines of text?) – marketed towards academics, it allowed students to learn touch-typing without the distractions of an entire computer.

Once you were happy with your touch-typed document, you then plugged the "keypad" directly into your Mac's ADB (keyboard/mouse) port... and the thing would sit there and manually re-type your composition into the computer's texteditor.

Education needs such "reduced tech" to return to teaching. Think of this one as a "more advanced typewriter" – although I own a few of those, too, and they're fantastic for pure composition.

Connect Keyboard, Press PgDn.

Or what I actually use for ssh on the road: https://github.com/klausw/hackerskeyboard

Google kicked it from their store because it still supports older Androids but it still works just fine on the latest versions. It's on F-Droid.

Comment by ProllyInfamous 20 hours ago

Is there really no PgDn on a phone?!?

I don't use them, but that is surprising! I would program one of my theoretical phone's physical side buttons to handle PgDn/PgUp [†] – similar to my old Kindle's layout. Do phones still have side volume buttons (e.g.)?

Comment by loire280 1 day ago

I agree this type of web design sucks. It's been common for more than a decade - I remember Apple getting criticized for using this on the product page for the old "trash can" Mac Pro in 2013, and it was already widely used back then.

However, it seems pretty clear to me they did this in service of a joke - you have to "crank" your scroll wheel to get to the content, just like you have to crank this device. I think it's funny...

Comment by eks391 1 day ago

I took several biomechanics classes as electives back in my undergrad, and in one assignment I remember comparing the energy outputs between the human and robot equivalents of different tasks, whether or not the robot was humanoid in how it was designed. The most impressive think that stuck with me is that humans are incredibly efficient, from an energy perspective, in anything we do, compared to machines. Every time we delegate a task to a machine, we are using several orders of magnitude of energy to do the same thing. For most tasks, it feels wrong, but it doesn't make me any more willing to give up my car. Maybe if I lived outside the US.

Comment by overfeed 1 day ago

> The most impressive think that stuck with me is that humans are incredibly efficient, from an energy perspective, in anything we do, compared to machines.

Humans are efficient, but not across the board. Trivial counterexample: walking is incredibly energy inefficient vs a bicycle or other wheeled conveyances whose primary dissipater is rolling resistance.

Comment by BadBadJellyBean 1 day ago

We're still pretty efficient while not having wheel shaped limbs. Running like humans works pretty well. So well even that we can chase a lot of animals longer than they can outrun us.

There might be more efficient ways to move but we are pretty well equipped by evolution.

Comment by overfeed 1 day ago

> We're still pretty efficient while not having wheel shaped limbs.

Agreed, but it was gp that brought up the human vs. machine efficiency argument. Machines can have wheels.

Comment by zaat 1 day ago

That's a strange comparison. Wheels are incredibly limited in the type of surfaces they can be used on.

Comment by overfeed 1 day ago

> That's a strange comparison

It's not strange at all, I was responding to a specific, incorrect claim. I even quoted the wrong claim in my earlier comment , and I'll repeat it again, with added emphasis

>>> humans are incredibly efficient, from an energy perspective, in anything we do, compared to machines

I simply provided contrary evidence to a well-defined, falsifiable claim. How is that strange?

Comment by zaat 1 day ago

Yes, but walking and moving on wheels is oranges and apples. It would be a relevant comparison if a robot with a movement mechanism based on two feet was more efficient than a human.

Comment by antasvara 1 day ago

The parent comment is quoted as:

> in one assignment I remember comparing the energy outputs between the human and robot equivalents of different tasks, whether or not the robot was humanoid in how it was designed

So I think the point in this context is relevant, even if it's apples to oranges.

Comment by zaat 16 hours ago

The point isn't that a humanoid robot walking is less efficient than a human walking, is that moving on a wheel is not the same thing as walking. For example, using wheels is not only less efficient it is barely usable for climbing rocks, going up the stairs and many other surfaces that makes the comparison irrelevant.

You could say that a robotic gun is much more efficient than a human in killing, that's another easy easy comparison of different tasks where robots win, but it totally miss the point.

Comment by jason_oster 1 day ago

I’ll admit, at first, I thought the human vs machine comparison was about humanoid machines. But that’s too narrowly defined to be a useful comparison. Most machines in use today are not humanoid.

Then to boldly claim that humans are more efficient at anything compared to a machine, just does not follow.

Comment by connicpu 1 day ago

If you live in most places in the US other than the urban heart of a few very large cities you have to take a huge hit to your ability to get places in a reasonable time frame without a car. I have hope some more cities other than NYC are improving the situation, but as it is the closest I got to using public transit for a commute was when I was going to one of our other offices in a different downtown area I would drive my car to the park n ride to take the train the rest of the way. The train saves time and sanity because traffic downtown is a nightmare, but that drive takes 5 minutes, and it would add 20+ minutes if I had to walk to the closest bus stop so I could take the bus up to the train station.

If you live in most cities in Italy you have to take a huge hit to your ability to get places (in a reasonable timeframe or at all) if you must do it with a car.

Comment by rahimnathwani 1 day ago

"Every time we delegate a task to a machine, we are using several orders of magnitude of energy to do the same thing."

Might this just be selection bias? I mean, if humans can't do a task efficiently, we're not going to do the comparison with a machine.

Some actions we do seem (to me) very inefficient when compared with machines. For example: grating carrots and brushing teeth.

Comment by vitally3643 1 day ago

No, it's evolution. Mammals burn a ridiculous amount of energy just existing, so evolutionary pressures tend toward more efficient muscles and body geometry.

Electrochemical reactions in your muscles combined with the mechanical advantage from the geometry of your joints and ligaments is simply more energy efficient than most mechanical or electromechanical systems. On top of that, our learned and evolved kinematic algorithms result in vastly more efficient control. Humans tend to be pretty good at using only exactly as much energy as required for a given action. Overshoot is quite limited compared to robots.

Your suggested actions seem inefficient, but if you look at the actual energy expenditure, mechanical means are much worse simply because mammalian muscle is so efficient.

Comment by rirze 1 day ago

There's a difference between consistency and efficiency.

I read efficiency as "Energy inputted to accomplish a task", in which case, biological systems are far more efficient than current-day mechanical ones. It's a tradeoff.

Comment by klaff 17 hours ago

I have the opposite idea after reading physiology books. The number I remember was 22%, for efficiency of a human being as a motor, driving pedals to create mechanical power. That's quite poor compared to an electric motor. And unless you want your fuel to be high-fructose corn syrup, your fuel is inefficient to make as well.

Comment by not_the_fda 1 day ago

The efficient mode of transportation is a human on a bicycle.

Comment by pants2 1 day ago

If you're comparing raw calories to output, yes. Even gasoline has a caloric value, but humans can't drink gasoline. Growing and preparing food for human consumption uses a lot more energy than pumping and refining gasoline, so at the end of the day, human efficiency gains are not that impressive.

Comment by arximboldi 1 day ago

that's a misleading equivalence because you're also not considering the energy it took to grow the plants that produce that oil millennia ago. perhaps comparing to biodiesel or alike would be better. but even then it underestimates the efficiency of the human body, because food contains not only the energy we use, but also the materials to build the body itself. so you'd need to account for the inputs into that biodiesel and then all the extraction of materials and production of the machine itself. biology is amazing

Comment by pants2 1 day ago

You also need to consider the energy released during the big bang as a prerequisite for creating that food and gasoline. The big bang released about 10^70 J of energy, roughly equivalent to eating 10^63 big macs

For more reference how insane 700W is, the average FTP of a world tour pro road cyclist (i.e., Tour de France) is ~350-420W/6-7W/kg. FTP (Functional Threshold Power) being the avg you can sustain for an hour without fatiguing.

My own is ~250W @ 3.12W/kg. I can't even hit 700W yet, let alone for over a minute. My 5 second power is ~640W.

Spend 30 minutes charging a battery and you should have enough energy to turn any flavour of pop-tart into carbon flavour.

Even without a battery, I could easily imagine designing an efficient single slice toaster that could handily brown a pop tart on a 300W budget.

You wouldn't need any sort of fancy toaster: anything small, rated >= 300W, would deliver cyclingpower from a rider of any skill.

Comment by kccqzy 1 day ago

It’s basically well known to cyclists that training with a power meter that tells you “watts” more accurately gauges effort and caloric expenditure. (Heart rate gauges subjective effort however, taking into account stress, caffeine intake, etc.)

It’s also interesting that the industry has settled on using watts to mean rate of useful work whereas calories to mean the total work including inefficiencies, despite that calories is just a unit of energy. A rule of thumb for cyclists is that in addition to usual unit conversions, the “calories” figure should be multiplied by four to account for energy expended by the body but not used for rotating the pedals. I don’t use rowing machines but I’m sure they would have a similar conversion factor in order to calculate calories.

Comment by andy_ppp 1 day ago

You can get a dynamo hub front wheel for push bikes: https://bikepacking.com/plan/dynamo-hubs-lighting-charging-g...

However you can expect around only 3 watts of output at normal speeds and you will need to put in around 5-7 watts of power for the same speed. This is barely enough to trickle charge modern phones.

Comment by Theodores 1 day ago

Annoying. Blame the Germans and their lighting laws for bicycles. I want human powered USB-C with enough oomph to power a modest sound system or lights, whilst charging my phone. The allure of USB-C is what interests me, but 3W is not much to work with. Also annoying, no rear dynamo for my bike, so I can't even double up to 6W.

I will probably end up with no sound system and just expensive dynamo lights, using a USB speaker that doubles up as a power brick.

There is a nice USB battery kit for dynamo that fits in the steerer, so it is soldering iron time for that, so might as well learn how to do USB-C power things.

One day there will be structural solar panel batteries that can be 3D printed into lightweight bicycle frames, so maybe I will stick to throwaway lights until then!

Comment by malfist 1 day ago

An untrained cyclist is not able to maintain 200 watts.

For an average untrained male cyclist who is 175lb, they should be able to maintain 1.5-2 w/kg over an hour, or 120-160watts. A beginner cyclist who's been cycling recreationally over over a year should be able to attain 2-2.5w/kg which is 160-200 watts. A recreational cyclist who's be training for several years should be able to maintain 200 watts.

Trust me, I'm a cyclist, and I cycle with a power meter.

Comment by kowbell 1 day ago

As an average male who is ~175lbs and untrained at cycling, this is hugely validating for my terrible idea; 140 watts is the max charging speed for 16" M5 MacBooks. I can finally stop thinking for myself and have my computer do it all for me, powered by my big beefy legs.

Comment by kccqzy 1 day ago

140 watts is the FTP. That means you can do it for an hour, and it will be an extremely exhausting hour and you will want at least two days of rest to recover from this workout before doing it again.

If you are not chasing watts, it’s much more sustainable to do 70 watts for two hours. You can probably do this every day.

Comment by malfist 1 day ago

This exactly. FTP is functional threshold power, it's the maximum you can physically maintain in zone 4 heart rate for 40-60 minutes and it's physically exhausting. This is hard work, hardest work honestly. If you have gas left in the tank after you could had a higher FTP. I'll get out on the bike and do a zone 4 workout and keep a steady state of 180-200 watts through the first 20-30 minutes, by the end of the hour or hour and a half of my workout, even with breaks to break, reset heart rate, have some water, salt and glucose, I'm down to 120-150 watts at the end of the ride.

Basically, you can probably charge your macbook at peek power for an hour every other day, or every day for a short while if you're okay with burning out eventually.

Expect to need to eat 400-600 calories and a lot of water each time you do this.

Comment by rootusrootus 1 day ago

That's solid. If my memory is correct, and my teachers were correct (both of these are suspect) back in high school, a human should be able to momentarily exert about 1 horsepower at maximum effort. We did an experiment on how much power we could output at maximum effort. We tested it by sprinting up some number of flights of stairs, and timing it. As I recall we did conclude that in round numbers the hypothesis was correct.

But that was 35 years ago and it was a high school physics experiment meant to be entertaining more than precise.

I've had the same thought and it's been a topic I've been this close to talking about at parties. If I did I'm sure I'd bore everyone to death.

Considering the difficulty of sustaining 700 watts vs 350 watts, we could've had some very well-burnt toast if they uninstalled the heating coils for the 2nd piece of bread!

Comment by Aachen 1 day ago

I thought toasters took ~1.6 kW, just like any other resistive heating device (space heater, oil-filled radiator, microwave oven, oven oven, hairdryer, kettle, under-sink water heater: it's allways 1500-1850W!) except for the ones on special circuits (shower, stove). Turns out, our toaster draws 850W!

While watching the video, I was wondering how they modified the >1kW device to produce a toasted toast in that short amount of time (I guess you could substitute instantaneous power for time up to a point, but the video wasn't that long), thinking maybe they removed one of the sides' circuits. Now I'm disappointed as well. Thanks xD

At low effort (i.e. active recovery can-do-this-all-day-every-day) levels, it's quite efficient. That assumes that you're fine with whatever let's say ~120w continuous can get you, which is what the m5 max 16'' mbp peaks at (in my case) during inference (ds4-flash)... so I guess it's quite usable, actually :)

Consider that you can do this as a working day because someone else is plowing the fields that grow your food, probably burning stored energy in fuels for the process

We're sadly not that efficient. The 150kcal/6h=600kcal/day you've mentioned aren't enough, and it takes more than 600kcal to create 600kcal plus transportation into your home

Besides, we won't stop existing, so any math about "chatgpt uses X kW and so it's better than hiring another human" doesn't work out. The human doesn't stop burning fuels when not in use: any LLM usage is additional energy that needs to be generated while staying within CO2 budgets

This is not a strong argument or at least a different area of discussion. Because you can say exactly the same for the electricity: you need more than the power. You need the coal+transportation, or power plant, or solar panels ...

I'm pretty sure humans are much more energy efficient ... for certain tasks ;)

Sure, do the math for both, considering also that the human will continue to run anyway and then see who should do the task to minimise worldsuck :P

I find AI helps a lot with my context drift (or attention deficit). I can now simply burst type questions one after another in a large prompt, then have the AI do all the relevant searches / data collections, and spit them out quickly, scratching many itches at once.

The problem is then that I get more questions, but AI can handle them faster than I can muster them up or type them. So it's a net win

"Tech companies have quietly abandoned their climate pledges to build gas-burning power plants that feed your favorite AI."

What I love is this quote is super-imposed with a background image that has gas-burning smokestacks but also nuclear cooling towers in the same field.

This is a bit representational of this particular line of protest against AI - just super confused about it all and thrashing out.

Green energy has been (technologically) solved, but instead we want to go back to manual labor as a source of power? Hilarious.

Comment by danbruc 1 day ago

Not only nuclear power plants have cooling towers. Here [1] is, for example, a coal-fired one in Poland.

[1] https://en.wikipedia.org/wiki/Coal-fired_power_station#/medi...

EDIT: To elaborate a bit, if you are burning oil or gas in a turbine, you do not need a cooling tower, the waste heat goes into the atmosphere with the exhaust. If you use fossil or nuclear fuels to produce steam for a steam turbine, you either need a river with enough flow to not boil all the fish if you reject the waste heat into it or you need a cooling tower to reject the heat into the atmosphere.

Comment by jszymborski 1 day ago

As a bit of an aside, I really like the idea of trying to design things with the constraint of it having to be able to run off a hand-crank.

I feel like it is not only an interesting engineering challenge but one that might lead to a more efficient and sustainable framing.

Comment by bko 1 day ago

Or we could... hear me out... build more power plants. The de-growth stuff is pretty evil when you take it to it's logical conclusion of population control.

Comment by jszymborski 1 day ago

There's a bit of a difference between population control and reaching a sustainable equilibrium. One can also argue the death of all life on earth is a pretty evil logical conclusion of infinite growth on a finite planet.

Comment by bko 1 day ago

What does "sustainable equilibrium" mean?

What are you balancing if not human growth? And how do you plan to do that?

Comment by icantevenhold 1 day ago

Doesn't it kind of work itself out?

If it’s unsustainable population growth there will eventually be some catastrophic environmental effects and the population will be reduced to a sustainable level. Of course living during that reduction could be a rather unpleasant experience but it probably also won’t last too long.

If it’s already sustainable everything is fine.

It's not more sustainable though. It takes more energy to grow the food to get the calories to metabolize to turn the crank than it would to run an electric motor or a engine to do the same work.

Comment by jszymborski 1 day ago

Totally true that what is and is not sustainable is more complicated than it first appears.

I think what I'm honing in on is the idea that hand cranks produce very limited, often interrupted power and are relative low-tech, both of which are directionally the right way for us to be putting our efforts.

From http://hpmor.com/chapter/64:

MORPHEUS: For the longest time, I wouldn't believe it. But then I saw the fields with my own eyes, watched them liquefy the dead so they could be fed intravenously to the living -

NEO (politely): Excuse me, please.

MORPHEUS: Yes, Neo?

NEO: I've kept quiet for as long as I could, but I feel a certain need to speak up at this point. The human body is the most inefficient source of energy you could possibly imagine. The efficiency of a power plant at converting thermal energy into electricity decreases as you run the turbines at lower temperatures. If you had any sort of food humans could eat, it would be more efficient to burn it in a furnace than feed it to humans. And now you're telling me that their food is the bodies of the dead, fed to the living? Haven't you ever heard of the laws of thermodynamics?

MORPHEUS: Where did you hear about the laws of thermodynamics, Neo?

NEO: Anyone who's made it past one science class in high school ought to know about the laws of thermodynamics!

MORPHEUS: Where did you go to high school, Neo?

(Pause.)

NEO: ...in the Matrix.

MORPHEUS: The machines tell elegant lies.

(Pause.)

NEO (in a small voice): Could I please have a real physics textbook?

MORPHEUS: There is no such thing, Neo. The universe doesn't run on math.

Comment by rpastuszak 1 day ago

Playdate (the came console) is amazing for this! I was really bored once and built a Claude Code remote control for Playdate.

Voice recognition was done via parrot + handy.computer Basically: different key combos were tied to different actions, e.g. \

    - hold A to speak
    - move the crank slowly to navigate
    - crank super fast to send the prompt
Eventually this became a universal remote control for the computers in my home (YAML file with bindings from Playdate UI → A11y events). Using the crank to control movies is fun!

(I can share the source -- just let me know if this is actually useful)

Also, I feel like the author and me have similar hobbies. A few years back I almost won a (re-sellable on Ebay) award for https://meat-gpt.sonnet.io !

(I lost to a gallery of 3d sandwiches)

Comment by Waterluvian 1 day ago

I really wanted to like the Playdate but it's such an unbelievably overpriced and underspecced toy. But the crank, which really looked like a gimmick, is oddly quite nice to have and I wish my kids' Retro Arcade had one.

I mean it's 100-160 mHz CPU, 16 MB RAM, 4 GB storage -- you could run diablo 1 on it!

Comment by Waterluvian 1 day ago

Yeah in retrospect I really got it wrong with “underspecced.” I really should have said “not colour.”

This all comes as a retrospective comparing it to my kids handheld for their MakeCode Arcade projects. The device that was 4x the price ended up on a shelf and I find myself borrowing theirs. I just wish it had that dumb crank. It’s so weird and yet I love it.

Comment by rpastuszak 1 day ago

The lack of colour is actually quite cool (and it’s a fun creative constraint). But the lack of backlight and usb (iirc) is annoying. The first because you can’t use it in bed and I like to play something cosy/silly in low light (https://untested.sonnet.io/notes/obsidian-for-vampires/).

The second - because now I need a companion app/script to handle comms over WiFi (bonjour). You can use cable, but if I could pair this with my phone… as a personal assistant - that would be amazing!

Comment by palmotea 1 day ago

> We chose a cheap off-the-shelf switchable voltage 20W hand-crank generator marketed for emergency USB charging. The Pi normally draws around 1.5A, but when it’s working hard (as it does when doing inference on the CPU), its current requirements can increase substantially, causing the generator voltage to sag below the Pi’s required 4.8V or even, in the case of a momentary 5A spike, to trigger the generator’s internal overcurrent protection and shut off the voltage output entirely, causing the Pi to brown out.

> To ensure the Pi sees a steady voltage when the full inference stack kicks in (and to afford crankers a little rest), we built a custom capacitor board [https://docs.google.com/spreadsheets/d/1Zv_Hsinvx_sWtdur4iWY...] to smooth out the generator’s output and act as a short-term (~20 second) power reservoir.

Somewhat off-topic, but could this capacitor board work with a small-ish 5V USB solar panel? I'm not great with electronics, but it seems like just the solution for a device I want to run with the panel.

My vague impression was it's not kosher per the USB spec to just stick a capacitor across the supply to even out the brown-outs, but this looks like it's doing some other stuff.

Comment by ggamecrazy 1 day ago

When I was at Peloton a long time ago, someone proposed an April Fools’ joke where we could announce a dynamo add-on that would let you power your house from your bike.

The math isn’t as bad as you might think: 200Wh (about a 60 min, somewhat intense ride) seems to be about 20 minutes for a H/B100. Still 3x, but not bad at all!

I remember the idea being dismissed quickly because people would likely actually want it.

Comment by hdndjsbbs 1 day ago

200W is pretty good FTP for an "untrained" cyclist. FTP is the maximum you can sustain for a single hour, but you're not going to do multiple back-to-back.

Obviously the peloton crowd is biased towards people who will have better endurance and higher FTP, but basically the upshot is you could run one card for one hour with the effort of a 100km long ride which most recreational cyclists do once a week.

> During voice agent startup, the slowest part are [...] in dlopen-ing large shared libraries (ONNX Runtime in particular) and in hundreds of small random reads off the SD card as Python walks the import graph.

Could this maybe be fixed by arranging the files on the filesystem in the order they're read? Or maybe importing the Python modules from a zip file (with no compression) would be faster, if that makes it easier to store them in the required order?

I seem to remember Windows having some sort of feature like that, automatically rearraging the data on disk in the order it's read when booting the system.

This is so cool; I wonder what the roadmap includes? I'd love to see if this could evolve from gag product/gift idea, to a solar-powered inference box on slightly more robust hardware, for instance, completely freeing the owner from any need to purchase a subscription or rely upon the grid for inference. That would be freaking cool and I'm sure would sell a ton if the models that could run on the hardware were sufficiently capable and could be piped into a laptop (which seems like the easiest part). What would the power requirements be to run a more capable model than the ones used, maybe a DeepSeek open-source model? Really curious but I'm unfamiliar with the technical details that might go into such calculations.
