Ordinary paper and card as electrostatic dissipative materials? - Page 1

timestamp: September 20, 2023, 04:23:33 am
content: I have noticed that my cheap surface resistivity meter gives 1x10E8-9 when used against paper or raw (uncoated) brown corrugated cardboard. I think it's due to the tiny amount of moisture that the paper absorbs from the air. Does it follow that I can push DIP ICs into a piece of corrugated card, put it in a cardboard box and call it safe? What if it was transported this way? I live in the UK where the outside humidity rarely dips below 60%. Indoors, we usually have the problem of too much humidity so I think the card will always be dissipative. It makes sense to me but I'm not qualified.I chose the dodgy tech subforum because this is my dodgy version of those fancy ESD boxes.Edit: having just watched one of Dave's videos on dissipative vs sheilding, I'm thinking it could be alright in the cardboard if it's then inside a sheilding bag. If anyone in a <60% humidity environment has one of those surface voltage meters, could you do me a favour and rub some paper or card in front of it and see if it behaves the same way as those pink bags/foam?

The design requirements for transmission and reception are very different. A receive antenna design uses a loop of thin material, like a tape. There's even a group who folds the tape into a figure '8'! These are very hard to analyze, mathematically, but in testing, they can be found to work well.But this guy, just makes up his own terminology and spouts pure BS. The sort of stuff that can't be analyzed, not because it is complex, but because it's pure BS!You can always spot such a con, by the fact that "this" experiment almost proved the principle or almost reached unity, or almost... blah, blah, blah, and they need a bit more money for the next experiment which should reach the goal!

content: In a recent Northridge Fix video while he was advertising his new short detection special power supply he said the reason he had to design a new one was because he used to use the third channel on his fancy Rigol bench power supply for voltage injection and burnt it out.https://youtu.be/kzcg5S8mAOM?t=330The third channel only supports 5 volts, so of course it is not designed for high current short detection with a thermal camera. He should have just used channel 1 or 2, they will be made for the full watt rating.Also almost all of the devices Northridge Fix puts their branding on are just drop-shipped unbranded devices from China. You can usually find the same device on Ali Express for less than half the price. Not saying they are bad, but they aren't Rigol.

It would be different it they were lower temperature devices that were mainly cooled by convection. I gennerally agree with the 'stuck in a block of wood bit though.

But it took a bit of squirming (sideways), to do controlled fall sideways.That old chair seat broke out, but the stronger edging material did not break, and the front edge was wedged, firmly, behind my knees, while legs tightly closed, folded in half, and knees against chest.Was even hard to breathe, there.Go ahead and laugh!

content: HeyI recently stumbled upon some Chinese soil sensors which claim to be able to measure NPK (nitrate, phosphorous and potassium) like this one:https://www.jxct-iot.com/product/showproduct.php?id=197(they claim to be the manufacturer). They sell between 50-100$, which would be a absolute bargain for such a thing.It is really hard to get some more information about those things, no teardown (they seem potted) or review as i searched. I found some docs how to use then:https://drive.google.com/file/d/19KSKdNDyZmARWAz-XHz9rnAY1IijCRcl/viewbut there is not a lot of info at all about them on the internet.My question is, does anyone knows how they work and if they are any good ? (i doubt it) From my limited knowledge about sensing soil, this is a quite complicated thing to do so, especially when doing it directly in the soil, and they claim a accuracy of 2% and a lifetime of over 5 years which seems really impossible. There are legit sensors who are able to measure the claimed metrics with a accuracy of around 2%, normally it seem to be done with selective ion electrodes, which are quite expensive, degrade quite quickly and only work in aqueous solutions and need to be calibrated quite often. Those Chinese sensor seems to use a different "technology" since it only has stainless steel electrodes.Any ideas/knowledge about this thing and the technology used?

As kjr18 says, it has a resistive heating element underneath it, and sucks a fair bit of current, shortening the life of the battery, particularly if you use it a lot.I can imagine if the battery compartment is tight, it could activate and drain the cells in pretty short order, which might be why they stopped making them.

Dodgy technology is not free from repercussion, particularly when hiding facts from investors...Nov 18 2022:Judge Edward Davila imposed a sentence of 11 years and three months in prison plus three years of supervision after released. Restitution will be set at a later date. Holmes must turn herself into custody on April 27, 2023. Appeal (of conviction) is expected.It is on most news networks. Rather than adding a link and driving traffic to any particularly one, you can search and select your own.ps: I know there were earlier discussions of Theranos . I followed the pop up box suggestion on starting a new thread since the old one has been inactive for over a year.

It talks in weird messed voices.I found some PR on it here.

So a refund might be possible but not certain (having been through that process many times).Should Apple have more controls/setting for people who want it? sure. Should Apple force over the air updates without the option to opt-out? hell no.But it's not an actual sky falling in mass refund issue, despite such a media frenzy/storm appearing around any minor Apple change. But do continue this forums hilarious support of perpetuating misleading/disingenuous reporting.

THOUGHT EXPERIMENTS: Transformer traversing a room - Page 1

content: Trigger warning: Highly theoretical.I’ve pondered this on and off for a long time, even partial answers have been few and far between.See diagram 1. An engineer is in a sealed room, the legs of a ‘wide’ transformer cross the room so that the coils and everything attached to them are inaccessible. A full range of tools and test gear is available, and the engineer can do anything required to measure the power being passed through the transformer to the resistive load.One solution is in Diagram 3. Cut the core legs and complete the magnetic path with new coils, join the coils with an ammeter and voltmeter in the circuit, job done. But that approach bypasses the question of what’s happening within the transformer core to pass the power.For a partial clue, consider Diagram 2., The engineer is in the room with a rotating shaft transmitting mechanical energy from a motor to a generator with a load. Once again, without some sort of invasive action only part of the required information – the rotational speed – is available. To determine the power, the shaft must be cut, and a torque measuring device inserted.This relates to stuff that I encountered doing my degree at uni, decades ago. Lagrangian theory, and intensive/extensive variables. In that context, what are the two variables that determine the power passing through the transformer core, and how do you measure them? Or is the idea of power passing through the core invalid?
