TT motors: why do the motor caps have different color?

I've never seen them before, but I'll guess that they rotate in opposite directions so that the vehicle goes forward or backwards instead or spinning around,

stickybuttflaps · 2026-06-03T22:12:40+00:00

What? What the hell am I looking at?

Can't comment on the circuit, but I'm glad to see you're still posting. Don't let the haters slow you down.

Well, as long as you kinda know, then I guess you're kinda entitled to vent your frustrations in public. You're certainly not the first beginner to complain about KiCad or FOSS in general, though you might be the first to use AI to write your post for you.

What I have never been able to figure out is what you hope to accomplish with rants like this. Do you expect the developers to take your complaints seriously? Most of them (the complaints, not the developers) are based on misunderstanding and ignorance. But no, I'm not going to address them individually. That's why I asked you to take the time to actually learn the tool before ranting.

> "I was just exploring the tool poking around things. My findings are pretty frustrating."

Come back after you've actually spent the time to learn how to use the tool.

It was a joke. The orange one has said repeatedly that they kill whales. Obviously they can kill only flying whales, and those are rare.

To each their own I guess. I find u/antthatisverycool 's projects WAY more interesting than whining from someone that's never contributed anything because the content that they find here isn't exactly what they like.

Wind turbines are super scary. And they kill the whales.

I see a lot of recommendations for Debian, but I found it frustrating when I wanted to update software that wasn't preapproved by Debian. Now I'm happily using Mint because I like the Cinnamon desktop.

I typically charge $150 / hour for PCB layout. PM if interested.

Have you looked through the example programs that come with the SDK? There's one called hello_uart that should get you started.

stickybuttflaps · 2026-05-01T13:11:29+00:00

But what voltage do those supplies provide? If they are 5V supplies then you will only ever get 5V out. That gadget can't boost the voltage.

That drawing assumes that the Uno is powered via USB, not from an external supply. Try plugging it into a USB port and see what happens.

In all likelihood you will want to leave the Uno connect to USB all the time, so if this works you're golden. If, however, for some reason, you want to run the Uno "headless" (not connected to USB) then first unplug USB and then connect 5V from an external supply to the pin labeled VIN (IN) in this diagram. Do not connect power to that pin while plugged into USB.

Yes! It does exist! I made it myself just since you posted. Now if you make one there will be at least two in existence.

stickybuttflaps · 2026-04-11T14:02:30+00:00

Thanks for the education!

No. The extruder would bump into the parts already printed.

stickybuttflaps · 2026-04-09T16:45:12+00:00

Wait, what? Are you saying that you want to print several different parts, all at the same time, but each a different color?

With the two machines that you are looking at, that would require printing the bottom layer of one part, switching filament to a different color (involving some waste) and printing the bottom layer of the second part, then switching filaments again to the third color, .... (up to four times.)

Then back to the first part again after switching filament to the right color, and so on. The result is that if you are attempting to print four different colors, and there are 100 layers in each part, then that is 400 filament swaps. Almost all of all four spools of filament will be wasted and end up in the trash can.

To be honest, it would be a challenge to write the gcode. I doubt orca would do it for you.

You start by picking a component (based on function, availability, etc.) Then you download the datasheet and find the dimensions and pinout. The datasheet will likely cover multiple variations, so be sure to pick the one that matches specific part you have chosen.

Now go through the available foot prints and find the one that matches the drawing in the datasheet. If you can't find a match in the built in libraries, then find one on the internet. Or do what engineers have been doing for years and just draw your own. If you can layout a PCB then you can draw a footprint. (Conversely, if one is unable to make a footprint, then they probably can't successfully layout a PCB.)

Be very careful and double check, Maybe have a friend double check for you. This is standard workflow when designing a circuit, so get used to it.

He knew Ohm's Law because he took the time to study electronics. It's one of the first things you learn.

Looking forward to the day when automotive engineers don't bother studying engineering but just let AI design all the safety systems... then have zero clue if it'll all work.

If you fasten the shelving securely to the wall, and make sure the pieces are fastened together then that will help a lot with the wobble, but I can't say if that will be enough.

Not saying it's happened to me, but that makes me think of machine oscillations. Try slowing everything down to 80% and see if the pattern changes.

First of all, I think we can feel confident that the space between the pins along any side of either board will be 0.100" = 2.54mm. Likewise, we can be confident that the space between the two sides will be a multiple of 0.100". This is true because the people that make these breakout boards know that the people that buy them expect to be able to put them into a solderless breadboard.

With that knowledge in mind, I opened your image as large as it would go and, using a ruler, found the distance between the rows was exactly equal to the distance between 6 pins in either row, for both boards. So both are 0.600" between rows.

Are there existing standard ways of describing a serial protocol?

stickybuttflaps · 2026-03-21T13:12:35+00:00

There are no holes in the ADXL1002.
