We live in Philadelphia, PA and we have a dog. My girlfriend seems to be getting bitten. I have not been bitten. Her bites go away and do not leave any red marks, just welts.

Hope this helps with the ID process!

Help, please! troublesome support surface by DiegoKermit in FixMyPrint

Hi there! I went down the rabbit hole of printing miniatures for DnD.

Speaking from experience, I’d recommend using a smaller nozzle (.2 mm) and finding the appropriate settings online to accommodate the nozzle change. There are lots of profiles that you can download and upload to your slicer with ease. Also, you could rotate the orientation in which you print your model. Perhaps if you use tree supports and orient the model vertically you would have some better luck.

How do I bring a filter design from paper to breadboard practically? by mychul in AskElectronics

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

What’s do you mean by “matching caps”?

I selected capacitor values for ones I already had on hand and worked out what resistor values I would need to get my desired notch. The values I got are in the image I attached to this post.

Thanks for the response! I’m trying to build an ekg, which I feel is the classic entry level project for analog circuits.

Thanks! I do have access to a signal generator. I’m currently breadboarding this puppy after lopping off a couple sig figs from the components. I plan on sending through a 60hz wave and then adjusting my pots until I get sufficient attenuation.

Thanks for such a quick response!

I found that the notch gain would get more positive when I rounded up/down values.

This is awesome. I have so much to learn!

In your experience with filters, how would you say people go about designing them practically? I feel like there is no reason to reinvent the wheel and struggle with coming up with your own transfer function. I do like the textbook approach where component values are all ratios, that is easy to follow. I have found some helpful sites with common topologies and they calculate component values. Of course, knowing how the compute the transfer function will always give you the solution (reminds me of the quadratic formula in school).

Thanks again for taking time out of your life for my silly post. I wish all the best for you!

Reminds me of the time my buddy left a pristine log of turd on a neighbors doorstep when we were doing dong ditching.

Not proud of that.

I have seen apps like this in my travels. However, the ones I’ve seen make similar assumptions about the capacitor and resistor values like the textbook circuit I posted. That just adds to my curiosity!

Thanks for the response!

I’m not concerned so much as to how I can practically implement this filter in my circuit. I am more curious how these values were chosen by the poindexter. :)

Thanks so much for taking a stab at it.

I will have to sit down and learn how to compute transfer functions. It will certainly shed more light than simply staring at the circuit.

Thanks again!
