    Does US electric code allow branching ?

    No. You need a single mains switch to throw to cut all power. There is no way to add your panel without asking the power company to shut off the meter ( you'll pay a disconnect + reconnect charge and your local code may not approve because there is no single switch. Add a sub panel to the main...

    turbo jet fan - feedback appreciated.

    What are the blue things? Why do some only have one wire? Entering that mess into a simulator will result in a "garbage in, garbage out," situation.

    Current sources in parallel...

    On my dual source power supply, I can set both to 0.5A and run them both in parallel through a 1-ohm resistor, I get a nice steady 1V across the resistor, indicating 1A total current. All my equipment is fine. Please explain why you would expect undefined voltage levels or damage?

    More fun with ws2812 this time XC8 and CLC

    Fun? 8-hours? We have vastly different definitions of "fun"!

    More fun with ws2812 this time XC8 and CLC

    The DotStar strands from Adafruit are way easier to work from because the timing isn't critical - you have a data and clock pin (4-wire with power ). And you can use much higher clock speeds for large refreshes.

    Impact of Tariffs on PCB Fab

    Bambu printers can definitely achieve 500mm/second movements but have you tried printing at those speeds? Read their material sheets, all materials are recommended to lay down material under 220mm/second. You'll end up with all kinds of strings (even at 220). Best results around 180 to 200mm/s.

    Impact of Tariffs on PCB Fab

    The extrusion temp of various resins range from 180 to 300°C+ which higher temp materials printing at much lower volumes per minute - and the higher temp materials can be a challenge without a heated build chamber.

    Impact of Tariffs on PCB Fab

    Since we are on the subject of solder tip holders, I recently made a drill bit holder and solder tip holder - I drilled some holes in a block of wood. I'd post the 3D CAD file if I had one - but I don't.

    How to make string LEDs?

    Didn't you recently post, in another thread, about how someone in Bangladesh was electrocuted by mains power and ask, "how could this happen?" Well, one way some of the 8000 people that are electrocuted in Bangladesh each year is because people cobble together mains powered projects without...

    Fixing board, Easy question HEX SCHMITT

    I don't agree that all channels in a 6-channel inverter fail at once. But, I think you should look at loose/broken/cracked solder joints near the chip if (what I assume to be) a pinball machine or video game shakes or vibrates. Try reflowing the solder on each pin of the chip. Just a quick...

    PIC KIT 3 not able to program dsPIC

    Microchip was giving them away the week they were launched if you ordered a sleeve of 10 PICs. I have one but never used it. Sitting in a drawer next to my PicKit, PicKit2 and PicKit3. The Pickit4 is hanging on a USB cable near my desktop.

    When we ask if it is genuine, we typically mean, is it made by Microchip?
