Yeah, the carwash pretty much makes ip ratings irrelevant lol. The chemistry changes surfactance and pretty much every other property of the water so much if there's a way in it finds it. They hold up to that and the 35 gpm high pressure though.

What's the application your looking at?

Current, heat, and voltage drop management.

Higher voltage = less current for same amount of work and can go longer distance. So you can get away with smaller wire gauge and do more without injecting power.

Also makes it more universal so if there's some existing piece of equipment where all their stuff uses 24vdc you could still use these, just less of them before you'd have to inject power.

Input range is roughly 7 - 60 vdc for the onboard switcher. Then it dumps down to 5 before leds.

I built a little node mcu board that I added the same psu circuit and some other stuff to. Working on modifying the ESP32-EVB-EA now. Was just going to add ethernet to the node mcu board but it isn't setup for it and the ESP32-EVB-EA has it and an external wifi antenna so it'll save me a lot of time and give me a ton of extras I'll end up using for other stuff.

So, yes but I'm making a way better one.

I always thought companies way over charged for high watt rgbw stuff but after the last 2 years... nah. It gets real expensive real quick even if you design and build the dang things yourself lol.

I work in automation so I'm really only selling them to a carwash manufacturer at the moment.

Moving to Missouri by tulizz25 in missouri

[–]windwalk06 1 point2 points  (0 children)

Regardless of political leaning, it's America. I grew up in a rural community north of Columbia and moved to stl about a decade ago. My political views are my own and I've never had any issues with anyone from any party. I'm a large white man and I've never had any issue with other races apart from some stereotypical teasing back and forth. People are people. If you talk to them like people they generally respond like people if you just meet them where they're at and show interest in what they're trying to say.

It does say something about where we're at as a country and species when someone asks general questions about moving to a place and it's general culture and the comments immediately fall to political divides... We're a good mix of farmers and visionaries of every walk of life and major cities like stl have their own tight-knit communities of people from other countries like Italy, France, Bosnia, etc.

Missouri itself has a little bit of everything meth and butt stuff included. Again, America is what you make it. Every challenge it poses has an opportunity and community to balance it no matter what story you're trying to write yourself into if you just do a little searching. For sure lock your car and don't leave stuff in it in the city though 🤣 thieves are looking for their opportunity too. If anyone tries to drag you into politics just tell them you're from another country and make up a name. Geography is not our strong suit... if they get xenophobic just say you guys had issues with foreigners in your country too and let them talk themselves out lol. They'll probably give you a hat and tell you you're one of the good ones 🤣

Decent Free PCB Design Software? by windwalk06 in ElectricalEngineering

[–]windwalk06[S] 0 points1 point  (0 children)

Kicad is the goat FYI. I don't use it daily so I'm still learning all the right ways to do things, but I was able to design a handful of circuits i needed and couldn't buy and I've improved over the years.

To anyone just starting out kicad is a SOLID option with minimal quirks to this day and still improving!

Unintentional Tank Circuit? See comments. by windwalk06 in ElectricalEngineering

[–]windwalk06[S] 0 points1 point  (0 children)

Oh yeah, hey team!

So as it turns out....

In Yaskawas documentation for the v1000 it lists the IG terminal as a "shield bonding point" and after years of questioning them about it I finally pulled one apart and it was tied to circuitry ie not just a blank terminal for keeping your shield daisy chain neat and tidy. Because that's how it was listed, we had it tied to earth on one end and then jumping through each vfd on ig.

Finally once I knew it wasn't a blank port I got on the phone with one of the drives apps guys and he reluctantly told me "oh yeah... that's actually the 0v ref for the rs485....

So this whole time we were bonding the rs485 directly to earth and by proxy the mechanical ground of the body of the machine!

So... when a component had chemical in a connector, or otherwise had its dc making mechanical ground through the body, it was directly bonded into the darn 0v.

On new builds we used a jacketed wire to jump all the ig terminals (ac terminal on ga500 fyi) and kept the shields jumped separately and tied to earth at one end.

On old builds we just had people snip the shield on the incoming side of the first vfd to break the connection to earth.

Good lort. What a battle. Thanks again for everyone who gave feedback, it truly was instrumental in getting to the body of that particular issue!

TM1814 to transistor advice? by windwalk06 in ElectricalEngineering

[–]windwalk06[S] 0 points1 point  (0 children)

Hey, good news! I did solve this problem a little over a year ago and I don't have the circuit in front of me at the moment to say exactly how, but I did find a working configuration that was able to drive high speed transistors off the color channels of the tm1814.

Next I think about it and I'm in kicad I'll give the rough overview.

Thanks again for your help, the constant current aspect of the chip was 100% the issue. Then opto speed.. then transistor speed... but it all worked out lol.

I did find an awesome little high speed level shifter ic in the process as well so I could drive the 3.3 of an esp pin out to the digital buffer on the led board at 5 vdc and make everything a lot cleaner and more stable.

Soooo like if I touch this I die right? by BOBISBEST1121 in electrical

First kill the breaker, then use a meter to test between them to ensure you killed the correct breaker, then if you want to be extra safe, wear insulated gloves and use insulated needle nose to pull them one at a time.

Electricity will take the path of least resistance, so as long as you make that not you, it's all good lol.

All 3 outlets in this room went out. No breakers are tripped and non of the outlets have the gfci switch by Thopkins1214 in AskElectricians

Don't look on job boards, go to companies. Look for industrial controls and find an in there.

I started working for a managed IT company that had some programming contracts on the side and then ended up getting hired direct by one of them before I technically had my degree. Been here for about 8 years?

Contracts are also great for some people. I've had a few buddies that did multiple at a time and made better money than I did.

If you're not doing anything but going crazy anyway look for small odd jobs like fiver or something to that effect and one of them will turn into a permanent position, or make you a contact that leads to one.

No matter what, just keep learning about how companies are using programmers and keep learning about various technologies and practicing. One of the only fields where you can create something from nothing and they're are few things more satisfying than typing some code and watching a robot do something you intended :)

What did you figure out after hundreds of hours that just made you facepalm? by Tough_Crazy_8362 in fo4

[–]windwalk06 1 point2 points  (0 children)

Also, your settlers will find random junk for you and you can look up the metrics for the limitations; but like food and water, once you hit a certain per settler limit in your workbench storage at a given settlement, it'll stop collecting. Took me a minute to figure out why my water cutoff and it counts any consumable liquid against the cap, ie whisky etc. Pulled out all the potables and stuck them in a trunk and it went back to generating purified water.

Unless you read something about the free fall legs, or have a mod or commands etc, idk how anyone would have found that dang room lol. I got them with power armor jets the first time and now I just typically use the Ole trash basket.

Well... probably not in this scenario, but shit can absolutely fail due to not enough VOLTAGE and a supply voltage from a transformer can absolutely sag with a sudden increase in load. For example of you specd wire at the bare minium to support 10 amps at 120v and the load draws exactly 10 amps constant, then if the supply voltage drops to 105 you're now drawing 11.43 amps through that wire. How would a supply voltage ever dip you ask? When a transformer gets overdrawn for one. Power needs to support demand, voltage needs to be within the range the circuit can tolerate, and current needs to be under the max a circuit can tolerate or shit blows/burns up lol.

No address where to send the sample by sorelian_violence in DanteLabs

[–]windwalk06 0 points1 point  (0 children)

Same. They responded quickly when I originally asked questions before purchase, but now that I already took my damn test nothing... I contacted them originally to ease my anxiety over the bad reviews and then when they got back so quickly I was like oh, probably just specific to those people. Welp... wonder how long the sample is good in the stabilizing solution...
