<p>Nickff - Maybe you could have phrased your response a little differently? Highlighting you had trouble following the OPs post because of all the idioms would have been more effect than demanding they change their approach?</p>

<p>I used Reeder for a year, but switched to Miniflux because I wanted an RSS reader that could be used outside of my Apple devices. I do miss having a mobile app of my reader, since Miniflux can sometimes be hard to navigate on a mobile device. I never seriously considered using multiple readers until now. Thanks for the accidental recommendation.</p>

<p>I like the idea of having a grid highlighting system, but didn’t see any info on what happens when you have more than 49 unique parts in your current 7x7 grid.<p>Any plans to allow for multiple unique parts in one cube? And if so, would you prefer to mix like parts with like parts, or mix different part types? i.e. one bin holds multiple types of resistors or one bin holds a unique resistor value and a button<p>Asking because I’ve tried both approaching when setting up lab spaces, but both systems sort of fall apart without the correct maintenance/tidying_up.

<p>This reminded me about an old blogpost I read. This linked post may not be the one I remember, but it's close[1].<p>Back in 2011 there was an earthquake that New Yorkers felt. There were New Yorkers who read tweets of people further south on the East Coast posting about feeling an earthquake, and then the New Yorkers feeling the same earthquake a few seconds later.<p>There were some news outlets that picked up the story which you can find, but not exactly what OP was discussing.<p>[1] <a href="https://www.ralphehanson.com/2011/08/25/earthquakes-social-media-xkcd-and-science/" rel="nofollow">https://www.ralphehanson.com/2011/08/25/earthquakes-social-m...</a></p>

<p>When designing hardware, you usually define what the expected operating environments are. Some typical environmental considerations are the min/max temperature, debris ingress, shock & vibration. If you know your product is going to operate in an area where material is likely to enter the product, then you can either try to keep that material out (sealing the product up), or make sure that dust entering the product won't cause failures (i.e. electrical shorts won't happen on a board by covering exposed areas with glue or making sure a mechanism can crush/clear particles). It's not necessarily more complexity in the product to navigate these constrains, but it is another thing to consider in the design.<p>For example, if you're making a phone that is going to be sold around the world, then you're going to worry about arctic/equator temps (will some of your components melt or ICs fail), salty sea air (will the product begin to corrode for people living by a beach), or fast moving elevators (will the speakers pop from a sudden change in pressure).<p>You can check out this manufacturers robot arms as some examples of existing products. They list some data sheets for their robot arms, including some arms that are IPxx rated. I don't think looking at robot arms is a 1to1 comparison for what you could expect from a humanoid robot since the considerations in the design process are going to be different.<p>website is kuka dot com/en-at/products/robotics-systems/industrial-robots/kr-agilus</p>

<p>6 months from announcing rePebble (Jan '25) to shipping your first units (July '25) seems like a quick turnaround for a compact consumer electronics device. Curious to know if these first units are closer to a white label of existing hardware or more of a JDM model.<p>Side note - I got the first pebble through the kickstarter pre-orders in my first year out of high school. Seeing something so novel was definitely a contributor to me switch from CS to Mech E and working in the consumer electronics space now. Thanks for making cool and interesting things :)</p>

<p>Thanks for the rec. I'm going to check out "Human Smoke". Now I want to recommend "Letters from a Self-Made Merchant to His Son"[1] which is a collection of letters that a man, who made his wealth through the Chicago meat industry, to his son who went to college. It gave a warming perspective of a parent who would express his love in one letter, and frustration towards his son for showing up to work late in another. It beautifully illustrates a "modern" parent-child relationship in a time period I often imagine as cold and distant.<p>[1]<a href="https://www.gutenberg.org/ebooks/21959" rel="nofollow">https://www.gutenberg.org/ebooks/21959</a></p>

<p>You could try a battery powered phone charger since it's a "relatively simple" first project. The big hurdle for learning these types of tools is usually "What buttons do I press to create the output that I want.<p>For the electrical side, there are plenty of schematics online that you can try to copy or use as a starting point. And the CAD side can be a simple box with snap fits. I'd recommend OnShape if you're just starting out since it's the lowest barrier of entry, but Fusion 360 is also good. All in, it should be <$150 for the PCBs + Components + 3D Prints.<p>After you get the satisfaction of seeing your device charge from something you made, then you'll start getting the itch and find more excuses to make things.</p>

<p>The school I went to had a common Dynamics exam. It was considered the first “real” engineering course you took, and was the foundation for a lot of upper div classes. Regardless of your teacher or class time; all students took the same exam at the same time. Professors would grade other professors students.<p>It was also normal for a double digit % of the students to fail the exam and retake the course (me included).<p>Its not exactly what people think of as a standardized test, but it ensured all students in the school had the same acceptable level of comprehension on the subject.</p>

<p>Sort of. UL and CE are certifications that declare a a product confirms to the standards defined by those groups. The main difference is that UL only focuses on product safety (i.e. Shock and mechanical hazards), while CE covers product safety plus environmental and health requirements.<p>UL is technically a global standard, but mostly used in USA/Canada. That's only two countries which already have laws governing what can and cannot be put in a consumer device.<p>I'm not as familiar with the history of CE, so I don't know why CE decided to cover environmental standards. But my speculation is that it's because CE covers ~30 countries with a larger range of laws.</p>

<p>Are you saying that what's happening is the permeability of the cell membrane changes with their physical states (from a scale of "more liquid" to "more solid")and that change impacts the transmission rate of the neurons? And an example of this would be an anesthesiologist putting you under is them making your cell membrane more solid to increase the resistance those neuron transmissions experience, just like adding more resistance to a circuit to reduce the voltage?<p>Disclaimer that biological sciences aren't my strength so I'm just trying to understand what you're saying.</p>

<p>For Stellaris, one of Paradox’s space 4x games, they have a team dedicated to maintenance and a separate team for DLCs. The result are large free updates that improve/rework on the mechanics which compliment the DLCs keeping the games fresh for years.<p>Usually the base paradox games feel like they’re “missing” major features which makes some DLCs necessary for a more full experience, but by the time that happens the base game is heavily discounted so base+dlc=full price of a new game.<p>Just felt like I have to add onto the paradox comment since I enjoy their major updates + dlc approach. Whenever I buy one of their games, I know I’ll probably come back to the game for at least 5 years.</p>
