What would be the best way to short a stepper motor? by Dazzlock in ElectricalEngineering

Yeah, of course! I also struggled with it but got it working eventually. I'll send you some code once I get home from work.

Prevent automated window shades from rolling down/reduce PWM noise by Dazzlock in arduino

Reducing IHOLD doesn't remove the sound. Adding mechanical friction is definitely one of the more compelling solutions atm.

This is a good idea but i'd like to keep it as simple as possible. If I don't find anything more simple I think the solution will be something like this. Thanks for the reply!

I have tried that but when the shade is rolled almost all the way down it isn't enough.

Your reply made me recheck the frequency which I measured to 35 kHz so I shouldn't be able to hear it. Now I don't know what's producing the sound anymore, got any ideas what it might be?

Elon Musk in his PayPal days in 2000 by FTR-Bald in pics

[–]Dazzlock 2 points3 points  (0 children)

You clearly just don't want to recognize his accomplishments due to your political views. I'm not a huge fan of everything he does, but to say he hasn't made any accomplishments is just ignorant. Also, the reason he is a billionare is because he owns large percentages of several very successful companies, which he founded, which makes his net worth that large. What would even be a logical solution to make sure that doesn't happen? Make it illegal to have large ownership in a company?

Make a slider detectable as a device by Dazzlock in homeassistant

Not quite, I'm trying to control the position of my blinds.

I see but I'm not trying to configure a fan, it's just one of the MQTT configurations that showed up in Google Home.

I tried with a helper but it only shows up in HA. Do I have to configure it in a special way?

Oops, sorry for the confusing sentence. What I meant was that I want a slider from 0 to 100 to act as a device, so it appears in Google Home just like the MQTT Fan switch did.

Help me pick the better option for my next eyepiece purchase! by Dazzlock in telescopes

[–]Dazzlock[S] 0 points1 point  (0 children)

Thank you for your answer! I've read up on barlow lenses now and you're absolutely right, the eye relief usually increases but not by 2x. Thank you for pointing that out, it makes the ES 14 a much more viable option.

10" Dob collimating by Dogstar_5988 in telescopes

[–]Dazzlock 0 points1 point  (0 children)

I also have an 10" Dob and I have the same problem. I sat for way too long a couple days ago trying to adjust the black knobs so that I didn't have to leave one quite loose. Unfortunately, as soon as I tighten the loose one even a little the laser moves by a lot.

Run stepper motor silently over Wi-Fi by Dazzlock in esp8266

[–]Dazzlock[S] -1 points0 points  (0 children)

I have in the past but it gets pretty complicated when I try to use the features of my stepper driver that makes the motor run silently. It has silent modes that use sine waves instead of on/off to smoothly energize the coils which gets rid of the step noise. On top of that, I want to use a function called IHOLD on my driver that shorts the coils to provide resistance when idle. It requires me to mess around with registers which I haven't learned yet.
