Hey,

my Name is Dietrich, living in Berlin (germany), and I am into Arduino since several years. Dronebotworkshop on YT is a great way to learn all the details! It is great how understandably Bill brings every sentence, every word. This is like the calm of a Budda 🙂
It has often happened that I have bought things directly through a Dronebotworkshop video, simply because it is so interesting and promising.

When tinkering then sometimes the errors flood the solutions.. then I'm lost. For a while. Then I have an idea and then it goes on.

I have a lot of questions and maybe I post here some.

Delighted to hear from you Dietrich,

You are not alone in this and sometimes we all need the serenity of the Buddha.  My background is Field Repair and I notice that I am far more impatient than other folks. I am not so willing to get "down into the weeds"  as perhaps a R & D guy might have the temperament to do.   As an example;  where I have been trying to fix a problem with Linux that is strange and evasive, at about the 3 hour mark I will just invoke the "sunk cost fallacy"  and do a fresh install.  Other guys will only just be getting interested at this point and may spend days trying to track down the fault.

It is a mix of our own personalities and our professional experience that inform our approach to getting "the job done" ...

Kind Regards

M

Hi Everybody, I'm Clint from South Carolina. I'm not completely new to the microprocessor arena but my coding skills are near non existent. I've already went through the brow beatings on the arduino forum so i consider myself a well seasoned newbie. I'm fairly good with the mechanical aspects of moving things via computer, now if I could only coerce the computer into following my instructions the machines and I could lead a harmonious life together. At any rate I've enjoyed following along with many of the projects on the workshop and decided to join the forum in hopes that some of you could tell me where to get better mosfets that don't die every time you apply power to them although I do like the pretty sparks they make.

Oh, and it would seem to me since we all know the value of the magic smoke contained inside, manufacturers should listen more closely to their customers and create better seals. It's gotta be a design flaw.

Gee Clint, if you blame the manufacturers for the rapid demise of your MOSFETs, you may be reducing the chance that people will offer advice lest they suffer the same fate 🙂

It's all in fun , besides why would I blame anyone else for what is clearly defective devices? At my age I have to laugh and make fun of my mistakes, It's way too late in life to start worrying about them. Perhaps i should have clarified that a little better, most of the data sheets I've seen on mosfets don't really mark the legs as + and - and s for switch, it was supposed to be a joke

My reply was also intended as  joke, looks like it failed too 🙂

The landfills are overflowing with MOSFETS!

1) Treat them as ESD sensitive. They are and ESD will change the parameters of a part sometimes before destroying it.

2) H Bridges are much more tricky, especially with inductive loads like motors!

you gotta admit better seals to keep the smoke in is a good idea

now I'm off to find the page where I can present my coding woes to you fine people so y'all can tell me how bad they really are.

@will and why wouldn't it be their fault , clearly i can follow instructions, well sometimes, but then again if the wire is only long enough to reach this pin that must be where it goes, had to be a problem in the code, I heard this on one on another you tubers channel , " if a bigger hammer don't fix it , it must be an electrical problem"

I know that's right . I'm still using one for a three way junction block tied to the emergency stop button on my milling machine

I’m a retired pharmacologist from the University of Lincoln (the one in the UK). I took up electronics as a hobby after I retired and I’ve spent a little time soldering together components (resistors to ICs) - but recently turned my attention to the Arduino. I’m old enough to remember punchcard computers and basic as a language (!) but my steepest learning curve is now Arduino coding. I have grandchildren, one of which is taking the first steps to programming via an early learning robot - so it’s great fun learning together.
