1st Gen. Lunch Table - General Discussion

This is less electrical power and more industrial controls. Maybe @daveeasa knows, I think BMF was tagging you b/c you're an EE also. The one EE I'm pretty close friends with, he was totally apt and capable of understanding industrial controls but he also had a schematic breakdown of the brewery controls we wired up, so ...

 

Thank you sir. I read about the 1st one. It makes sense, but only a little. These are on little 1hp 480v motors. They barely pull 1A. That doesn't seem necessary.

Unacceptable. Engineers know EVERYTHING.

I was actually a radar tech in the Navy. Didn't know what the blobs were, just how to fix it if they weren't there.

 

Here's the power schematic for one of them:

 

From what I’m seeing online, a 3 phase reactor is just a simple inductive filter to filter current spikes on a motor circuit. Remember, from electrical 101, current across an inductor can’t change instantaneously.

it can also act as a low pass filter on each phase branch so it filters the voltage as well above a certain frequency.

 

My whole career is software so I'm near useless with anything in the physical world beyond 10% of shifty level handyman stuff.

 

It’s amazing what management thinks of us engineers believing we can be an expert at everything that goes on engineering wise at work. I was just asked to dig into someone’s software written in C++ and PERL for an embedded CPU. We have software engineers who do that all the time and it’s not something I want to figure out personally.

We need a smiley here that can roll it’s eyes, how am I supposed to express myself?

 

I'd gladly trade you for some truck mod time on that one

 

Ha! I hear you both, believe me. I've seen everything you're talking about and for some reason I thought Dave had an EE background, it's probably his electrical/wiring endeavors tainting my brain.

I grew up in a heavily-startup world where everyone has to know a little (or a lot) of everything, else you need to hire 3 people when you've only got enough capital to pay one salary, and I tended to hire people from similar backgrounds, so my viewpoint of the real-world is probably pretty skewed!

My degree is actually EE. Thought it was CE and I was close to CS, only shy maybe one or two requirements on that? Also shy PreMed by Orgo and I think Molecular Biology. I was just totally done with school and knew there was no point to giving a f about the degree, software is all about job experience.

 

We did do some programmable hardware in school though and I really enjoyed it. I wanted to work on audio, mobile or home, but it seemed like by 1996 all of those glory days were gone, cheap crap shipping out of China took over from high end stuff made in the USA or Japan. Meanwhile, dot.com boomtown was raging in SV so that's where the magnet took me.

 

Bose up here in Natick, MA is always hiring but from one I guy I talked to who worked there is that they work you to the bone even though they pay well.

I already missed my window for getting into designing car radios for AC Delco because I didn't know the companies flew people to interviews for free and I thought had to drive from Atlanta to somewhere in Indiana to interview for a co-op job. (still green being the only professional in my family at the time)

 

For some reason I want the type that frowns shaking it's head with eyes rolling.

 

If I could believe me, I would. I get much greater satisfaction working on my truck (or yours) than doing my job. Probably because I haven’t worked on anything both challenging and exciting for a while.

 

@Shifty If you ever have a question about FPGAs, I’m your guy. I design with them, simulate them, test them and troubleshoot them.

I also specialize in DSP as well and design software radios, filters and FFTs. Usually more specialized than the canned IP the vendor provides for them.

Now everyone is wondering…what the hell is an FPGA?

 

if it has a red wire and a black wire i can figure it out.

 

all I heard was White Lines.

still his fault.

 

Clearly there is a drainage issue. As water-flow is a community issue, this drainage issue is clearly a homeowners association issue. You should demand to know when they are going to resolve this drainage issue that is devaluing your property & enjoyment of the neighborhood.

 

Hard to believe but storm drain at my neighbor's property, new gutters and clear drains for my house as well as a drain at the base of the driveway. We've had rain for 6 months almost every day, just everything is soaked.

The mud pit is from the maple we felled to make room for my fleet of Toyotas.

I would really like a level slab in this spot, after rough grading, as thick as I can, with integrated drains that could serve parking and maybe basketball with a super high roof and a garage door, then make it into a workshop. But the setback is 10' side and 25' front so I'd be tighter on space than if I just did an outdoor slab and a portable hoop or something.

Or just quit and give up, tough to fight the uphill battle.

 

Don't add a driveway. Add a patio. Add a 'sand box'. Add a gravel size/tire block size interaction test bed. Add a veranda.
You probably should have whatever be water permeable. Likely some rule about how much hard surface you can have per lot.

Throw camo netting over it.

 

Yup, Miami Bass is centered around samples ripped from early hip hop, funk, electro funk, and disco. They love ripping from Kraftwerk, Afrika Bambaataa & Soulsonic Force, Midnight Star, Parliament Funkadelic, and lots of stuff in between.

Like, the crunchy beat in that song is jacked from Kraftwerk's "Numbers". The cheering at the beginning is something sampled at the beginning of Afrika Bambaataa's "Planet Rock". There's another version of that song I posted called "Planetary Deterioration" which samples the witch from Wizard of Oz right before a break that dribbles off into a classic bass breakdown. The bongo section sounds like it was ripped from the Incredible Bongo Band. I forget where the bells come from in the song, but it's another one you'll hear elsewhere. It's pretty incestuous.

I wish Google+ was still around. There was this one time I found a specific sample that was in a Bjork track, that was also in a Depeche Mode track, and exact same one in a Everything But the Girl track, and all came out within roughly a year of one another, it's not clear who started it, or if it was just something pre-programmed into a synth?

You could go nuts chasing all the samples down.

 

The lot slops significantly, just past our current deck is a 15' drop and the storm drains empty 15-20' after that then it flows to a creek that goes sideways through the button of a valley. Half our lot is this green space preserve area, tons of trees, some recently fell a few months ago. Good overgrown paradise. Easy to drain downhill, my firewood shed has a 30' drain to where the storm drain dumps.

A flat slab with good drainage and a roof with gutters, it'd rule.

We used those line reactors in the Telco room in the ATCT and numerous outlying communication sites. They help with harmonics on certain pwr circuits.

 

Freeze!

 

Rock!

Free bass!

 

I got pissed off at my limited shop space tonight and threw my shop vac, which broke the latch on the lid.

This, it seems, was a bad idea. I last used it to vacuum up a crapload of drywall I had to sand out while patching some walls.

Fortunately it didn't get very far. But nobody makes a new lid.

R.I.P Ridgid wet/dry shop vac. c.2005-2023. You had a good life, and I really hated how goddamn bulky you were. I hope you suck a big tub of chubs when you make it to dead vacuum land.
