I hope it involves fire

i am paid to show the engineers in my lab pictures of charred and burned hands resulting from electrical accidents and how to work with exposed conductors

im also paid to show them arc flash and make sure that all of our electrical cabinets are kept clear of hazards


also who touched the poop on the heat press

what they're trying to get at is that a voltage high enough to pass a deadly current through your heart has to exist

people who say "current kills, not voltage" are forgetting that; a lead acid battery can source current hundreds or thousands of times greater than that which will kill you but 12 volts isn't going to drive a deadly current through your body

makers are basically people that couldn't get a degree to be a real engineer, so they like to play pretend with equipment they know nothing about

people who call themselves makers are actually a couple steps below actual hobbyists because they need everything spoonfed to them in the forms of arduino-centric tutorials

edit: I looked into the makerspace in my city a couple years ago before I realized how poo poo makers are and the list of equipment was lower in quality and variety than the poo poo I have at home - except for the laser engraver that they did useless poo poo with like etching logos into hamburger patties

oh i thought they were the ones who look down on tutorials

I actually don't know the proper definitions but I blame hackers/makers for hackaday going from an interesting site to a non-stop feed of "holy poo poo this guy figured out how to blink two LEDs with an arduino" a couple years ago

no poo poo, you can die from like 60 volts if you grab an exposed conductor and exposed return with wet hands. the current will take a path across your heart and kill you

as i said, the major issue is the positioning, not the voltage

the human body isn't ohmic, and you can make a few general approximations that will give you a rough estimate, but "higher voltages mean higher currents" doesn't do as much for surviving an incident than preventing the current from pathing over the heart

no one is arguing otherwise we're just criticizing the simplistic and wrong "current kills, not voltage" line that people repeat

Bad news: everything including web sites will change over time. It's probably changed again/more since two years ago on top of that. It's a waste of time to pine/grudge/gripe

Alternately: no one gives a poo poo what you thought of some web site two years ago

okay

I felt smart the first time I used a 74HC14 with a resistor and a cap to make an LED blink, then played with the values to get different rates.

Then when I wanted something other than a 50% on 50% off blink I felt super smart using a couple diodes to make it basically use one resistor for the ON cycle and one for the OFF :shepface:

the 555 never made intuitive sense to me, it was all witchcraft inside
the 74HC14 setup on the other hand was a great learning experience because I could visualize the circuit path a lot easier

555 makes a lot of sense if you look at a block diagram of what's inside it; it's almost the same concept as that Schmitt trigger NOT oscillator except that the threshholds for switching on/off are set at 1/3 and 2/3 VCC instead of at whatever voltage the input stage of the logic gate feels like working at

Sure, if I could go back in time I'd tell my past self that Actually the 555 block diagram in fact makes perfect sense, and furthermore it's really the same thing as what he got working but improved.



exactly what my teenaged past self needed to hear to grasp the concept

yes actually because it's just a slightly more complicated version of the same thing

if you thought this instead of going "durr literally magic" then maybe you'd have had a shot at understanding it

edit: literally lol at this guy arguing against the idea that you can learn more easily by building off of concepts that you already understand

there's nothing wrong with using micros to blink stuff

Really though? Only a few thefts in the last few weeks?

I guess they don't count stuff like equipment missing enough equipment that it's cheaper to buy a new one as a theft

fwiw i see this sort of learned helplessness in my students ("help I tried to install x and it didn't work" "what did you try and what didn't work?" "I downloaded the thing and tried to run it and it didn't work and I don't understand what's going on just fix it!") and honestly a lot of time the greater kindness is to try and discover what they actually want to do and help them do that

that's called the X/Y problem, as in "they wanted to do X but mistakenly thought they needed to do Y to accomplish it and were seeking out help for that"
