    USB Output Board Sourcing

    Back again haha. I’ve ordered new parts to fix the problem in my last post where I detailed a blown up USB hub. Right now I’m focused on getting my equipment back up and running because it turns out when the USB hub blew up, it shorted out some of my electronics that were plugged into it. I’m...

    USB Port Switch Blown Up

    Oh, and @3DDave The power supply doesn’t seem to be outputting anything as of right now. However I don’t think that rules out the possibility that it could’ve gone bad and sent 120 through the Arduino Before completely dying. I don’t think I need the power supply anyways so I will not be using...

    USB Port Switch Blown Up

    Ok so I found out that my room may/may not have ground. I read only 50v in between Ground and Hot on another outlet. have no clue why it was 50. I don’t really understand how The system that I have could be working for months before but all of a sudden went bad overnight. I was using it...

    USB Port Switch Blown Up

    I’m not trying to fix it. I just want to know what the problem might be because I don’t want to get another one just to have it blown out again. If the problem was with the unit that’s fine, but if the problem could have been caused by a component that was plugged into it, that’s something I...

    USB Port Switch Blown Up

    Update: all of the components that were plugged into the port died except for one. Not good...

    USB Port Switch Blown Up

    I have a four way USB port that just had one of the on/off switches smoke up. Could this be caused by the button being stuck, feedback from the device it was plugged into? For reference, the device I had it plugged into was an Arduino Uno R3. It was being powered off of the DC barrel Jack and...

    Traxxas Charger Blown Up.

    It is a Traxxas EZ Peak Single charger. I haven’t got around to fixing it because I have been working on other projects. Here’s a picture what the board is supposed to look like...

    Traxxas Charger Blown Up.

    @itsmoked I’ll borrow my friends charger and see if I can figure it out.

    Traxxas Charger Blown Up.

    The other side of the board is just green PCB. It’s not a through hole component. You can see the burn mark to the right of the capacitor.

    Traxxas Charger Blown Up.

    Some factory worker wired my charging adapter backwards so it blew up my charger when I tried to plug the battery in. I’d like to see if I can fix it because this charger is discontinued by its manufacturer. The part that blew out looks to be a SMD resistor, but I’m not sure. I think the heat...

    Reverse polarity Question

    That is the spec from the diodes I already have. I am getting a different bridge rectifier online that has 4A max. That is the one I am talking about currently that has 420v RMS...

    Reverse polarity Question

    RMS voltage is 420 so I should be good getting that one.

    Reverse polarity Question

    If I were to buy one, does the voltage rating matter as long as it’s above the voltage that my circuit operates on? I can only find 600 V bridge rectifiers.
  14. Sam Neall

    Reverse polarity Question

    OK. I didn’t know if they shared the current or not. I am fine with a voltage drop because as I said I’m going to be running the driver on much lower than 12 V. So, assuming that you recommended that I use a rectifier, you’re saying that the idea I proposed wouldn’t work? The reason I’m so...
  15. Sam Neall

    Reverse polarity Question

    So the bridge will just take whatever shield pin that’s putting out a positive signal and automatically link it to the positive terminal of the driver then vice versa for the ground? I never knew you could do that. Also the output of the driver is 1.2 amps nominal 3 amps max. Would the bridge be...

    Reverse polarity Question

    I have some 50V 1A rectifier diodes laying around. Will they work or will I have to order different components? I’m assuming I would just put the rectifier on the negative and only let electricity pass back into the driver. Is that correct?

    Reverse polarity Question

    I have a small diffuser driver https://www.amazon.com/dp/B073322QF8?ref=ppx_pop_mob_ap_share that I would like to hook up to an Arduino motor shield...

    Project Quesions

    It is a racing simulator. Around 6 races at 10 minutes each is around the time I play during a session.

    Project Quesions

    I suppose I could do that, but how long with that set up last in continuous operation. If I could, I’d rather use the Power supply that I have currently to charge the battery because If the battery gets discharged, that trickle charger won’t be able to deliver power itself. With a power supply...
