comment Optimizing an Arduino code
Nice! Given the level of accuracy this approach could potentially shoot for, I'd also suggest measuring the actual resistance of Rc, R1, R2 rather than using the nominal values

comment A cron job for rails: best practices?
@dtc running rake via cron is quite wasteful as it needs to load up the rails environment each time. dj or sidekiq keep an instance(s) running. So my preferred use of cron is to poke a webhook that will enqueue the required job. That's lightweight and you get the benefit of using cron as a scheduler and dj/sidekiq as a job queue.

comment Arduino LCD 2x16 and PCF8574AP works well for limited time
That sounds/looks like the data stream gradually gets out of sync. The I2C lib seems to rely on some judicious delay() code to get it right. Have you tried with the standard LiquidCrystal library? If not, I'd suggest rewire and test that. I'm expecting it would work just fine, in which case the problem is definitely a matter of getting the i2c comms synced.

comment Clarification on LED strip specifications
Without knowing the components on the strip, hard to say if it will work at all at 6V, or how sensitive to voltage variations around 12V it is. Try it? If matching the voltage is too much trouble, might be easier to consider another strip. Without power supply, you can probably find single-color "dumb" strips for say US$5/m e.g this one which says 5V but in the pics you can see stamped for 6V

comment The voltage across all points in this circuit seems to drop once an inductor is added
Have you checked the transistor is still OK? Looks like the circuit will short thru C-E once L1 gets up to full current. Do you need a current- limiting resistor in there somewhere?

comment Is it professional to correct misspellings of my name?
+1 for best answer to the actual question. "How and when" is really the key to approaching the issue professionally. Definitely do not cc: all; that is not professional.

comment My rude/offensive flags on insulting comments were declined
@dext0rb: exactly. But I also puzzle over why EE.SE is the problem child. Having been around various SE sites for half a dozen years or more, EE.SE stands out as the main one I've participated in that really can't seem to get "technically informative and genial" right.

comment What is the equation for the 555 timer control voltage?
haha, I'm stealing Russell's idea. From now on, I think I'll just call them 555duinos;-)

comment How to challenge the deletion of an answer?
Scott, now it sounds like you are trying to moderate "style". My primary objection is to the fact that moderators stepped in to delete the answer within 20 minutes. That was IMHO, overly-aggressive and unnecessary moderation. I suggest a much better strategy would have been to just leave your comments as to why it was a "bad" answer and then give the people working on the Q/A a chance to self-police.

comment How to challenge the deletion of an answer?
Hi Scott, I get that was your opinion. But I think it led to unnecessary and overly-aggressive moderation. Give the community a chance to self-police like on all the other SE sites I use. But I didn't post this question to argue the point. The question is "How to challenge the deletion of an answer?" not "Why was my answer deleted?".
