Tell us about yourself!
Probably a mistake on my part, but I see nothing for Step 1. See attached screen shot.
thanks! I will search 'harder' in the future and try to catch these good deals. And I can hope that any 'replicas' work pretty much the same. I am a newbie regarding the programming and any incompatibilities would probably stump me.Thanks again!
Where do you find Pi Zero W for that price? (Lowest price I find is twice that and probably a cheap chinese counterfeit.)
thanks! It seemed that way but I wasn't quite sure...
Great job, looks excellent!Wondering: did you put any kind of countersink on the back of the bar so the copper has something to grab onto when flush with the iron bar? Or does it hold pretty well anyway?
That makes sense. Certainly many of the instructables are not the simplest solutions, generally focusing on learning and fun. But since I'd seen so many simple systems using arduinos and such I thought that as a noob I was just missing something critical. Thanks for reply.
This is probably a stupid question, but since the sensor has all necessary adjustability, and 3.3V output, why can't you just power the LED directly from the sensor output? And for higher amperage applications, just use the PIR outlet to trigger a relay and use the PIR power source to power the target device? Like I said, this question may be stupid, especially since so many 'ibles/applications seem to use arduinos even though functionality of the circuits appear relatively simple (to me, a rank amateur).
Excellent ible. Good examples of problem solving, research for modification of circuits with good technical explanations, repurposing, error correction, DIY techniques. this ible did not just show how to make the device, it provided a lot of insight to the process of creating a bespoke electronic device. I am very much an amateur, but I think this 'ible was very useful.
BS ChE 1983, MS ME 1985. Yes really, though sequential, not double major (that is beyond my capability). And not an English major, so the rule that you cannot use the common contraction is not allowed in that instance is not known to me; when I have time I will consult my "Elements of Style". Thank you for that valuable contribution to the discussion, though it seems more of an attack on credibility. Please do the research yourself: every dry cell manufacturer says basically the same thing, that RT, dry storage is best. In some cases (like EverReady) they say the cold in a refrigerator could damage the cell.
I've degrees in chemical and mechanical engineering from UC Berkeley and 30 years experience in materials engineering and I've learned that things are generally more complicated than they appear, and that for every issue there is a answer that is quick, simple, and wrong ("chemistry 101": what you are referring to is characterized by the Arrhenius equation; I am well aware of it, but don't let my knowledge of one factor blind me to all the others). Since you already know more than Duracel, visit some other battery manufactures sites for expert response. I will not respond further and take away from this excellent Instructable.
duracell clearly states that room temperature storage in a dry location is preferred. www.snopes.com reviews this urban legend with input from several battery companies.
