@infinitesimalsimplicio Easy. It means the LaTex interpreter isn't installed in chat. There, what do I win?

eurgh, this question is a bit scary - electronics.stackexchange.com/questions/161670/…

@Li-aungYip why? what is the worst that can happen?

Be nice, even towards Supavillains :-)

@infinitesimalsimplicio Is @Li-aungYip a Supavillain? Who would have thought that? :-s

:D

@jippie: looking at it a bit closer, it's not as bad as I thought

i had thought a lathe motor would be a couple of kW, i.e. significant amps

it appears that they are only actually maybe 1/3HP (250W)

@Li-aungYip Morning mister Supervillain.

now that circuit as shown will probably spray radio interference everywhere, but it's not a market product so who cares

I was being a little bit sarcastic, I don't think it is a good project for "looking forward to learning electronics and circuit design however all i know how to do so far is order the parts and put it together"

If you look closely, there is no high voltage connected to the MOSFET's.

Although I didn't read all the text that goes with it.

i read it as - you need to bring your own rectifier circuit

the VFD circuit he linked to assumes you already have a source of rectified DC

Sparky would be a nice username on EE.SE ...

Shoot, it's already taken

Multiple users can still share the same name.

The user id number identifies us :-)

How about "Let the Sparks Fly"?

Ark Angle :D

Or Ark Angel

Arc

@jippie snarky would be better

hum, where could I harvest a low resistance >40mH inductor from...

@PlasmaHH Digikey? ;)

@W5VO harvest as in smash something around me to get it out because I want it now and can't wait for it being delivered... of course, hm, where is the nearest digikey storage facility... and my crowbar... ^^

@PlasmaHH As far as I know there is only one digikey warehouse

dang

or at least warehouse location

hm, zero zeroes souonds bad...

@W5VO I'm guessing it covers about half the town of Thief River Falls.

gnah, sometimes getting the right parts is a nightmare...

@PlasmaHH Wait till you need just the right XO, and your boss wants it next week.

@ThePhoton if I would still be working for a company that builds any stuff it wont be a problem to hook into the order process and get anything no matter what it costs (almost) ... but for my private use these days, even when I have a part, it is too often that just digikey or mouser have it, and I wont order three transistors there...

lol @pls

hey guys have any of you used IR distance sensors for measuring water/fill level of a container?

especially in narrow containers (not like using sonar in a huge water tank)

@KyranF theres a problem with narrow containers?

how much did 8051 cost in 1970s?

@EwokNightmares the narrow container part is really just an issue of beam width/FOV between detector and receiver, and particularly with sonar, if the sonar module can reject the 'rim' and just tell me the water fill level

I am not sure if IR reflects off water enough to be useful for distance measurement

@KyranF what kind of sonar module?

if you have access to phase information couldn't you detect the echos off water vs. echoes off metal/glass?

sure, could do some DSP to tune in to water-only reflections. If that's a thing.

@KyranF lol not sure

I know, that's why I'm not taking you seriously

:(

need a pro on this one

see if some of these lurkers have done something similar

good luck then ;)

thanks matey
