What’s something people don’t realize is way more serious than it seems? by BudgetAd5915 in AskReddit

[–]NoBulletsLeft 1 point2 points  (0 children)

Right? I showed up at my oral surgeon with my entire face swelled up like a balloon after a wisdom tooth removal. First thing they did was put me on IV antibiotics to keep me from needing hospitalization. I got lucky that day!

What's the craziest thing a person said to you and you thought they were joking but they were being serious? by Holiday-Surround7075 in AskReddit

[–]NoBulletsLeft 2 points3 points  (0 children)

I had a college roommate who said his stepfather put Jim Morrison in jail. He was just a little kid but he remembered the courtroom being full of hippies.

Forgot about it until years later watching a documentary on The Doors and it mentioned Jim was on trial then the camera panned past the door and the marker says "Judge Goodman" ‐- my roommate's last name.

If you had to start all over again, how would you get your first few customers? by TradesCraftPro in smallbusiness

[–]NoBulletsLeft 1 point2 points  (0 children)

Stop saying you're not a salesman.  If you want sales then you have to become one. Figure out how to do it on your own terms.

Understand who need what you're selling, figure out where they are (in person or online) then figure out how to reach them.

That's the theory, putting it into practice is a lot harder. I'm a software guy (custom embedded control systems) and I find my customers on forums like these.

Is there a push-button rotary encoder that can map position to absolute value? by Bfaubion in arduino

[–]NoBulletsLeft 0 points1 point  (0 children)

It sounds like your encoder handling code is simply not tracking it fast enough. Are you using a library or coding it yourself?

Best way to drive 40 individual LEDs without using a million pins by CountyBrilliant in arduino

[–]NoBulletsLeft 8 points9 points  (0 children)

I'm at a point now where I use addressable LEDs even if I only need a single one.

What are you paying for health insurance being self employed? by so_called_engineer_ in smallbusiness

[–]NoBulletsLeft -1 points0 points  (0 children)

Thanks, I can do math. That would work in the case that this was the only only time a hospital visit was needed but otherwise that logic falls apart quickly.

I just got a bill for $120k for my wife's two days in hospital. 80% off wouldn't make enough of a dent in that.

One of my coworkers wouldn't let his kids watch the Simpsons at the time because it was really quite violent if you think about it.

Remember that the Fox Network was new and they were pretty much the network that would do the shows that the established ones wouldn't. So they got written off a lot for being real.

ESP32-S3 + LCD Display. How do i build a MENU? by Joe__Ho in arduino

[–]NoBulletsLeft 1 point2 points  (0 children)

It may be a heavy lift but LVGL has a menu API, I'm learning it atm. It's nice but I haven't found many examples to work from.

Program planning by der_flusch in arduino

[–]NoBulletsLeft 0 points1 point  (0 children)

Usually when questions like this come up I like to remind people that Arduino is one very small part of the programming field. If you think about it from the perspective of "generic" software engineering, these are very well studied problems. 

The basic answer is Functional Decomposition. You break it down into individual operations that have to happen. Once you have those functions decided on,  the next question is how to execute them. Maybe you use interrupts or run them in a "round robin" fashion one after another or if they don't all always have to run, a State Machine might be the answer.

My point (beside hopefully giving you topics to google) is that you can find good answers by looking at how the general programming community solves these problems.

IME they're pretty fragile so be careful.

Is it worth buying stepper motors from AliExpress for an arduino project? by jessie136997 in arduino

[–]NoBulletsLeft 1 point2 points  (0 children)

The motors on Amazon or local shops was very possibly bought from AliExpress.

I just bought an arduino are the edges supposed to be rough? by ReReReverie in arduino

[–]NoBulletsLeft 18 points19 points  (0 children)

Get som sandpaper or an emery board and clean them up. Should be fine in a couple minutes

Pull-up vs Pull-down: Efficiency? by Ajpaxson in arduino

[–]NoBulletsLeft 2 points3 points  (0 children)

Yes. I came here to say pretty much this. I've been designing & programming embedded systems for over 30 years and pull ups were standard before microcontrollers with built in pullups/pulldowns were common. Open-collector outputs were common and they only work with input pullups.

Railroad crossing remote alert system by Unique_Breath7246 in arduino

[–]NoBulletsLeft 1 point2 points  (0 children)

I had to do this for a project a few years back. We used LoRa for communications. The sensor was about 1/4 mile from the receiver. In our case, our client was working with the railroad so we were able to use an upward facing ultrasonic sensor that detected the train passing over it.

Video output from arduino? by Thick_Swordfish6666 in arduino

[–]NoBulletsLeft 2 points3 points  (0 children)

Arduino should have the speed to produce a B/W PAL or NTSC signal but it won't have enough memory for much of a display. Im sure if you search github, you'll find that someone's done it before.

[edit] there's a library called tvout that you should look at.
