One does not have to have climate anxiety to want to fly less.

With you on this, haha. Big tech has heavily crowded the wearables space, with questionable intentions and uses of personal health data.

Additionally, when doing research around kinetic / thermal energy harvesting technology for a wearable design project (gesture recognizing smart ring) for school, we found modules to have far too low a volumetric energy density (W/mm^3) to be useful, where size matters more than anything else.

Musical instrument design is a well saturated space as well…

re: 12V automotive LV systems: it’s a little more nuanced than that. teslas cybertruck will be running a 48V LV system[1] and while relays fuses efuses and DCDC converters across the LV system have to be rated for higher voltages - you gain efficiency back with I^2R losses across the entire harness, and can drop your required wire gauge since the necessary current carrying capacity is reduced by 4.

So it’s a nuanced trade off, and if the industry shifts (which tesla is banking on since they’re the ‘leader’) then economies of scale can be reached with higher voltage fuses switches relays etc.

My buddy and I solved the uMouse challenge for the final project in our college robotics course in ROS, with custom path planning and speed run and all…

it was such a great feeling to see the mouse complete the maze.

I disagree. You’re getting caught in the semantics; the notion of 20 $5 coffees makes sense and is an easy and relatable way to reframe $100.

Yes. That is how biometric data works; if my finger gets cut off I can no longer unlock with touch ID on my iPhone.

Wonder if they have a backup ID method of some sort or if it’s solely iris data

“When we came down to stay at the station starting in 2001, we brought everything with us: showers, toilets, generators, pumps, kitchen sink…” recalls Chris McKay, an astrogeophysicist at NASA’s Ames Research Center in Silicon Valley, whose name is still visible, written in ink on the Yungay research station wall. But despite the humble settings and the lack of water, “it was magical,” he says. “We would sit around after dinner and talk science. There was no phone, no internet, just us.”

A driver can be electrically modeled as a series resistor and inductor (very approximate model), I imagine that couldn’t be hard to add in.

Why use a micro at all? You could have implemented the entire circuit with a couple extra discrete components to reduce complexity.

Thanks for putting downloads behind a paywall.

Wonder if a program like this would be made available to students, or if there’s a way for students to get involved.

I'd imagine those are designed with keeping your focus on the road in mind, by doing things like limiting notifications to only incoming phone calls while you're driving

How common are programming languages designed with base languages other than english? This is the first one i’ve seen.

UAV futures is also a fun youtube channel to get started with and is a little less technical than joshua bardwell at first.

to have your mind blown by experienced fpv pilots, check out Nurk FPV, Johnny FPV, Mr. Steele, and Rotor Riot.

FPV is a disproportionately expensive hobby ... every hard crash can cost you between $20 ( broken motor bell) to $200 (cost of entire drone when dropped in water and electronics go poof). Still great hobby, highly recommend!

That sounds pretty dope, check out corewars!

Yeah exactly - the key is having a strong advising network to make sure you’re on the right track throughout your time in undergraduate.

I’m currently an undergrad student considering studying robotics eng. at my university. (Olin College of Engineering)

It depends on how the university structures their program, but for us it’s extremely open-ended, besides a few basic fundamental courses. They essentially want you to choose a concentration and pursue that concentration in your robotics projects throughout the 4 years.

It’s a risky choice for us, as unless you have some cool projects to show at the end you could end up ‘not concentrating in anything’ in particular, as robo is such a general field. But if you know what you want to do the flexibility can be nice.

[op here] - thanks for your kind words.

This entire project really exposed us to some of the challenges of the edtech space - mainly how solving the problems of the current edu system and making an edu product that people want rarely actually overlap.

But regardless, developing a sort of custom curriculum for those couple hours of 1:1 teaching and refining that curriculum on the fly, and seeing what concepts kids picked up quicker was super interesting and honestly one of the most rewarding parts of the project.

[op here] - thanks for the recommendation, we'll check out AntMe.

In hindsight, Corewars was a stupidly hard game to try to teach the intricacies of in a few hours, and because it's based in Assembly it's also mostly irrelevant to 98% of modern day programming students or new grads will be exposed to.

However, as an experiment in UI design and offering a visual portal into the internal game mechanics, this was a dope project.

Yes it is... will have to give it a shot sometime!

[op here] - Yep, when we stumbled across this idea we really, really liked it... however, this appeared to be a really neat solution to a problem that didn't actually exist.

Lots of profs are super busy with grading, securing tenure, research, and ultimately don't really care that much about the fine details of their course content. Motivating profs to document their entire course, class by class, with teacher notes, is really hard.

Here's an example of an olin college course opened up to the public ... it's a pain in the ass to make a course 'teachable by others'. https://courses.olin.edu/e4h/

Also on top of the above barrier, +1, creating a strong community out of profs who care about teaching would be hard.

Heyo - OP here, thanks for the kind words. Periodic reinforcement and having a video based / more interactive guide than just an embedded gdoc would all be super useful in helping kids learn faster and get to a competitive level quicker ... but with that said, Corewars is not a great game to start teaching kids with limited coding experience by any means. It's too hard to pick up - other games would serve this purpose much better. However, if we ever hop back into the edtech space, we'd certainly be interested in chatting with you at some point :) Cheers

Adi here - Thanks all for the advice, comments, support, and tips on ... not getting electrocuted(?)!! It's been a while since I've worked on the Corewars in India project so I'll answer some of your questions the best I can :)

Have been an HN lurker for ~1 year and it's super exciting for my first post to hit the front page! Looking forward to posting more interesting projects in the future!
