proee··on Beyond Meat fights for survival
You are not a vegetarian
proee··on Hand: open-source Robot Hand
Maybe this could be an add-on option for the K-Scale robot that is coming out soon? They want $1k for a 5 finger end effector hand.

proee··on Inside the box: Everything I did with an Arduino starter kit
This is actually a very sad comment to read. My childhood was spent buying up every Forrest Mims circuit book I could find at my local Radio Shack, and then trying to figure out which circuits I could bring to life given a very limited amount of components I could source.

I'm not sure what it would take to make these kits more exciting, because I find them ABSOLUTELY AMAZING.

I could rattle off 100 cool projects to make with these dev kits, especially coupled with a 3d printer.

proee··on The Effect of Noise on Sleep
So just use some good quality earplugs?
proee··on Congestion pricing in Manhattan is a predictable success
Some changes, like having a highway bypass a small city, can be catastrophic to local businesses. A restaurant that might have hundreds of out-of-town cars go by, now has only local residents.
proee··on Airlines are charging solo passengers higher fares than groups
This must be a new thing, because I've experienced the opposite. I needed to book 7 tickets, and the price was much higher than a single ticket. So I ended up adjusting the quantity and saw the price increase at around 4 tickets. So I ended up splitting the purchase into two transactions. However, after purchasing the first 4 tickets, the following price for single ticket was now slightly increased - so they were really playing some games or perhaps there was limited availability that was adjusting prices real-time.
proee··on Designing a low-cost high-performance 10 MHz – 15 GHz vector network analyzer
Can you please create a high speed oscilloscope next? :-)
proee··on Adobe deletes Bluesky posts after backlash
No love for Adobe. I have fond memories of their Updater downloading 1GB plus "updates", even though my trial EXPIRED.
proee··on Sleep is essential – researchers are trying to work out why
Running improved my sleep quality dramatically. Now the problem is, that if I take a day off running, my sleeping suffers. Curious if people that do weight lifting (which I'm considering) get great sleeps? Maybe I can alternate between cardio and weight lifting each day?
proee··on Cardiac arrest deaths among marathoners have decreased, study finds
I don't know if this is true, but my cardiologist said that everyone who trains hard for a marathon has some level of heart damage from the excessive training. This sounds extreme to me, but I was in to see him for some AFIB episodes that were triggered from pushing myself too hard. It's worth noting that endurance athletes are 2 to 10 times more likely to develop AFIB compared to non-athletes. So this is a bit of warning to apply some level of moderation to your training.
proee··on Steam Networks
Except you can ONLY use steam for heating and transporting it over distance is not efficient. If you turn steam into electricity you can use it for ANYTHING and transport it over long distances efficiently.
proee··on Burning in woman's legs turned out to be slug parasites migrating to her brain
Most rat lung cases in Hawaii are on the Big Island. Not sure why this is but worth noting if you are traveling. Beware of raw produce at farmers markets and from small organic grocery stores.
proee··on Cheap blood test detects pancreatic cancer before it spreads
There seems to be a ton of benefits to doing all kinds of blood work - from vitamin deficiencies, hormonal changes, cancer signs, etc. Our system is very reactionary in that we order all these tests AFTER we get sick.

Why is there not a more proactive approach to getting bloodwork done with as many tests as possible? We should see this type of service like going to the dentist.

Seems like a good industry to disrupt.

proee··on CADing and 3D printing like a software engineer
When you start designing products with lots of gears and linkages, does animating/simulating your design become critical? What CAD tools are best for simulating your design, or is this even the right way to verify all your mechanical items are working together as expected?
proee··on Show HN: I designed an espresso machine and coffee grinder
Nice job! You should add an about us page to tell your story and your mission. Even use pictures of yourself in the marketing because people love to support independent coffee companies. I hope you get rich and famous for all your hard work.
proee··on A simple math error sparked a panic about black plastic kitchen utensils
Wood is safe, but since it's organic has the potential to fuel the growth of molds, bacteria, and other microorganisms. I'm not sure the best way to sanitize wood from these elements? You could light the wood on fire, but then you wouldn't have any wood leftover.
proee··on Air Canada to remove free carry-on from basic economy
What else can they take away from economy class at this point?
proee··on Geometric line-art of Wacław Szpakowski (2017)
Perfect art for a classic Etch A Sketch.
proee··on Malware can turn off webcam LED and record video, demonstrated on ThinkPad X230
I wonder why Macs stopped using record LEDS. Seems if they are hardwired into the enable signal of the camera you would have some piece of mind.
proee··on Phased Array Microphone (2023)
What is the most practical application for this technology? Could you use it to pinpoint sounds coming from a car like a squeak?
proee··on Salmon return to lay eggs in historic habitat after Klamath River dam removal
Then why couldn't they make that work for this damn? I'm assuming there must be other motivating factors for removing the damn.
proee··on Salmon return to lay eggs in historic habitat after dam removal project
I'm surprised we could never engineer a proper salmon "elevator" to bypass the damn. Given the price of removing the damn, there seems to be a huge budget for creating some sort of high-tech Robo-elevator to scoop the fish out and drive them way upstream in a robo-vehicle.

Maybe a giant net that lies at the base of the damn, and periodically lifts out of the water to catch the fish and automate the transportation of them to ideal next step drop.

proee··on Show HN: A Marble Madness-inspired WebGL game we built for Netlify
How many people worked on this project and how long did it take to develop? Nice job!
proee··on The Skyline algorithm for packing 2D rectangles
This looks useful for auto-placing parts inside a PCB.
proee··on Four dead in fire as Tesla doors fail to open after crash
The tolerance on many doors is such that even with a slight amount of damage, they are "physically" unable to open. The latch mechanism can get "jammed". Per the NTSB, they recommend that all electronic locks disengage in the case of an accident. Does Tesla follow this recommendation?

It's possible the vehicle was damaged in such a way that none of the door could open because of mechanical interferences.

proee··on Four dead in fire as Tesla doors fail to open after crash
In reading a bit on this topic: According to the NTSB, vehicle models with automatic locking doors should automatically unlock after an accident.

This begs the question did the door automatically unlock? Perhaps the vehicle was so damaged that the door could not be opened due to structural damaged to the door itself.

proee··on Four dead in fire as Tesla doors fail to open after crash
This seems like a huge failure on the part of the NTSB. Tesla is getting a lot of attention for this incident, but are there other manufactures that would have had the exact same problem given this same incident?

The entire point of organizations like the NTSB is to prevent unsafe cars from going into production.

The NTSB has given this type of door opening a green light. WHY?

proee··on Standing desk might be as bad as sitting all day
Standing all day will not help your VO2 max. You need to get your heart rate up.
proee··on The Cult of Microsoft
I read somewhere that “growth” for the sake of “growth” is like cancer. When the mission of an organization is to grow at all costs, bad things will inevitably happen. I imagine the redwood forest was cut down with such ambitions, but sadly nobody thought to put the brakes on operations until it was too late. I’m not sure what the answer is. Perhaps if the vision for the company is strong enough the growth can always be the byproduct of successful fulfillment of the vision. Then the organization can just always align on ensuring the vision is worth pursuing and analyzing it from a broader viewpoint.
proee··on Show HN: I built a task manager that separates "do" and "due" dates
NotePlan is my favorite comparable app. It has super nice apps for Mac desktop and iOS. It also syncs your data to your iCloud account in text files so very good for privacy in that you are not storing you data on their servers.
