  • Schematic review

  • If I were you, I would not step down the 24V, but use that to drive the motor with pwm. It requires a bit different H bridge but overall it would be simpler. But if you already have a converter module that is good enough this works too.

  • In that case I would omit the extra transistors and use only the optocouplers.

    What sort of application is this? Having 18V somewhere and a 5V supply too that can output several amps is quite unusual.

  • Obviously. No idea what I was thinking.

  • Is it okay that there is no stop state? It can only drive the motor in either direction, bit there is no OFF state with your inputs.

  • Please don't use non perpendicular lines and draw in a clearer software if possible. Its quite hard to read.

    What is the point of the push-pull BJTs? With the optocoupler you could drive the nmos gates directly. If you need more current to drive the gates (unlikely for a small motor), I suggest you buy dedicated gate drivers. They are tested and not expensive. If you have the 18V available already, using the optocouplers directly would be a lot simpler.

  • So I installed Arch Linux... Is this it?

    Jump

  • I also felt a little underwhelmed, I thought the installation would be more difficult.

    If you are not in it for the memeing I find it to be a great distro.

  • What can I say, I didn't want to wait on my provider lol

  • I also vote for a writeup. This sounds awesome!

  • nano 8.1 released

  • At first I did, but i really like vim now

  • Ugh, and the code is so bad. I love it!

  • I think the real solution is repairable gadgets. A microusb port costs pennies and if the phones were repairable at all, it would be a 5 minute solder job. The same is true for USB C as well. It might be more durable, but it can still break and it feels so stupid to replace a decive because a single cheap part broke.

  • I liked microusb. I don't know what everyone is doing with their connectors, but I never had any contact issues.

  • Is the golden rule really good?

    Jump

  • Sure, its very effective. Someone commits a crime, everyone gets turned into gold statues. Seems fair.

  • Nike’s self-lacing Adapt BB sneakers are losing their remote control mobile app

  • Then it still doesn't take away anything from you. How would an additional embedded web based control panel impact you negatively? If you don't use it just don't use it. But it ensures longevity and makes the device entirely self-contained.

  • Its still stupid. No reason there is no embedded web interface. That is such an easy thing to do. Like routers have been doing for ages.

  • This should be required from churches

  • Why leave the cult for a second cult?

  • Ctrl + Shift + A

    Jump

  • Yes, really. If my move tool is set to layer move, dont change it just because I used the select tool for something completely unrelated. That is the typical dumbed down big colorful button approach that I hate in modern corporate software.

  • What popular product do you think is modern day snakeoil?

    Jump

  • Sounds impossible. The way they turn the screen red is by reducing the blue light transmitted through the LCD panel. You cant turn the screen red and keep the blue light at the same time.

    Unless its an oled screen. Then it is a stupid implementation. You could just reduce the blue light then.

  • Stop comparing programming languages

  • I do embedded. Its all C. You can't replace it.
