Anyone have any clue as to what could be happening?

Please @ me so that I get a notification, I don't normally come on here

Does the person asking the question have SDO on the external ADC connected to MISO on the ATMega32u4? That's my guess but I haven't been able to verify this through the datasheet/googling around

Quick question, in this question - arduino.stackexchange.com/questions/39556/…

@rdtsc Would your op-amp potentiometer idea involve monitoring the mean of the signal in real time while adjusting the pot?

"Subtracting the mean is only okay if the signal is ergodic, i.e. the mean at one point = the mean of the whole signal. A hpf will probably be more resource intensive but give better results. A hpf might introduce artifacts in the higher frequencies if the stopband has ripple"

A friend helped me out

The signal in question is just readings from a load cell with no load on it (but there is still a very small DC component, the mean comes out to 1.125).

Yes, the DC component should be a constant. It probably isn't a perfectly still constant, but I think for my purposes it is safe to assume that it is.

I didn't feel like this deserved a full blown question

Hey guys, random question. Is there any error associated with removing a DC component from a signal by subtracting the mean vs. using a high pass filter?

"Coplanar connection" is a term I did not know existed, but is exactly what I needed. Thank you, @ThePhoton!

Does anyone know of a small connector that would allow to separate boards to attach at their sides? For example, the right angle plugs in this page (I would just try to get those but the link leads nowhere) molex.com/molex/products/…

Yeah a CNC machine will be much better

Stupid question. If a schottky diode #1 has a larger forward voltage breakdown than schottky diode #2, is it safe to assume that #2 has a smaller forward voltage drop?

Oh probably sending them out to a house, but I might use a mill

I'm a noob

Altium (but the free version) and I don't even know what you mean by PCB process haha

Thanks guys!

Ok

Essentially what not to do

Does anyone know of a website/document that has a good summary of PCB design rules?

Hey guys

Perfect. Thanks!

What size drill bit is usually used for through hole stuff?

The smallest drill bit I have is 5/64 of an inch and it seems way too big

Is there a DIY way to drill holes for through hole components?

Question

Are batteries inherently noisy?

Thanks for your help

Oh, yeah this circuit isn't going to be subject to anything above room temperature

The subtleties of the differences between certain types of capacitors has always escaped me

Is there that big of a difference between the 3?

I looked polyester film up and I think you're right

My guess is ceramic

Could anyone tell me what kind of capacitor the one in this picture is?

lolol

I have a very simple question that I didn't think warranted a new post

Wait. If there is one tab labeled GND(TAB) but also one smaller pin labeled GND(TAB), does that just mean that they are connected? This is for a voltage regulator, by the way

Yep! Thanks

But I've never seen it before

What does "TAB" stand for in GND(TAB)? I can link the datasheet if need be, but I figured that it would be common enough that someone would know

Also, I remember seeing a room where I could message the moderators. Does anyone know where I can find it?

Oh, the arrow keys

Also, how do I scroll up on this chat?

But I can't figure it out for the life of me

Is there anyone here who is willing to help me with an Eaglecad problem? I would make a thread, but it's something very simple that I don't think is worth a thread

Is anyone here willing to help me with a grub problem?
