content: Pricing aside, at least it works. And beacons can actually be a surprising nuisance in congested areas because they are transmitted at 1Mb/s and 10 times per second per AP. I have seen somebody do the math on it; turns out that beacons alone can clog up several percent of available transmission time in the area. It doesn't help that they are sent regularly all the time without coordination and an AP which doesn't hear you has a decent chance of interrupting your packet with this junk.

content: I fail to see how this is any different to any bog-standard consumer access point made anytime in the past 10+ years. Even the earliest, crappiest consumer access points allowed you to adjust transmit power (even if it was a crude "low, medium, high" setting) and the beacon interval. Any half-way decent access point will also allow you to disable the legacy data rates.This is literally a product (or more to the point, custom firmware) that doesn't need to exist. However, proper RF planning is one important aspect of a good wireless network.I am amused though, this company uses all kinds of bullshit marketing terms like "low radiation", "eco" and "electrosmog" but stop short of claiming they are "safer for people and animals" or any such nonsense. Although the uneducated people who would buy this crap could easily come to the conclusion that this was somehow the case. They've chosen their words very carefully so they can't be sued or have claims made against them for making misleading claims or breaching consumer laws; wank-words aside, they are actually correct in what they claim.

It's easy to talk about "proper planning" and forget how hopelessly clueless the general population is. Paying for a pre-set unit may legitimately be the only way for some.Half of their website is FUD and BS, fair enough.

content: According to the datasheets, I see in the video around 100rpm with only half the leaves actually turning, meaning around 2 watt per leaf. The tree has 36 leaves, but 18 are turning. I estimate that each tree in the video is generating around 36 watts. This is actually very good for such a pathetic wind capturing device. Maybe on a truly continuous windy day they might achieve 100 to 200 watts total, but without a huge spinning mass as a flywheel to smooth out wind gusts, these trees are useless as a smooth power generator.The mechanical structure of those trees and just available thickness of wiring ensure they would not survive 10kw of power generation without both breaking and burning up wiring.

Counterfeit LM35 sensors that sort-of work - Page 1
Forum section: electronics / general

author: cleo
author_rank: Newbie
timestamp: September 30, 2018, 12:57:29 am
content: I've been trying to reuse a handful of LM35 temperature sensors that came with various lipo battery chargers. All of them malfunction when connected directly to things like Arduinos. They do work properly, however, with the battery chargers. After a lot of testing, I discovered the sensors are capable of drawing up to 8 mA of current (~100x of spec!) and heat up internally to give an output corresponding to about 54 ˚C. I further discovered the reason the sensors work in the battery chargers is that they limit the current to the sensor to about 0.5 mA.I concluded these are not real LM35s, and that whatever they are, Chinese battery charger designers know about this behavior and design their sensor circuits to work with counterfeit sensors.Here are pictures of the sensors. They're all labeled LM35DZ. One of them was really a blacktopped LM35CAZ. The only explanation I have is that they're some sort of defect sensors that were reclaimed and resold. The most unexpected aspect was that this seems to be common enough to design circuits to use these.I'm curious if anyone else has seen behavior like this.

timestamp: October 02, 2018, 04:15:44 pm
content: I don't think it's a plain BJT, because the measured voltage between the output and ground wire when I power the sensors from the battery charger is always the expected voltage for a real LM35. Plus, any of the sensors give accurate readings with any of the chargers, which I wouldn't expect for something that has to be calibrated for each different component.In any case, I checked each pair of leads in both polarities, with multimeter diode check and found 3 junctions, with drops of 0.686, 0.636, and 0.645 V, which isn't consistent with a BJT.

content: I'm pretty sure such speakers can be build, so no scam there. But... why would you? I see clear advantages in traditional speaker designs where the magnetic field of the winding is symmetrical around the core, always providing a centric force on the speaker. This "flat coil" design on the other hand seems quite a challenge to correctly align the speaker "cone" without it snapping to one side. I suspect it to be way less robust.The rest of the claims.. is marketing wank.And the website sucks. this "new, modern" websites with just one gigantic picture, two polemic lines of text and a button screaming "CLICK MEEEEE!!!!!1111one" in your face... I just hate those.

content: Most of the time reverse engineering at this level involves masking parts of the IC and selectively exposing portions to UV to erase the security bits or use a laser pointed at various parts of the die while it is operating to cause it to glitch and get into a state that bypasses the security. In either case the goal is to allow the memory contents to be read out by conventional means, but IC designers have learned these tricks and increasingly have included clever ways of preventing it.

However, those monsters focus 1kW in a tiny area. With elements on a chip being that small, heat alone may wreak havoc and make them useless for reverse engineering.

This lecture will also delve deeply into the twin opposing reactions of vibratory electromagnetism: radiation and its mirrored opposite condition, gravitation as well as implications on spin, angular momentum, energy, forward time, as well as their mirrored opposites including: dark matter, dark energy and the emerging notion of backward time."We will also explore the practical application of these mathematical discoveries and how they can be utilized along with hertz EMGR (Electro-Magneto-Gravito-Radiativity) to better understand time, the Inverse Square Law, biology, DNA genotypic and phenotypic expression, vacuum energy and matter transmutation.​

content: I'm disappointed that when R22 was getting close to being phased out, residential use freezers went to using R134a rather than R410a that replaced R22 for most other uses. The boiling point of R134a at -26C is nowhere as good as R22 at -41C. In contrast, R410a has a boiling point of -48C, better than R22, but operates at higher pressures so historically came at a much higher overall system cost.For those who wonder why that makes a difference when water freezes at 0C, the idea behind a good freezer is to freeze the water as fast as possible so the ice crystals remain small. In some cases, dry ice or even liquid nitrogen is used for that purpose.

The prior freezer went bad and bought a replacement. The old one had coils at the top. It naturally circulated the air. The new one has them much lower. So, my cans froze and the stuff on top was too hot. I now have to run a fan inside to prevent temperature stratification. I will be starting a go fund me soon to bring this great idea to others.

They even label these SSD storage units as 512Gb drives when in fact they are 480Gb.The following video appears to be by a company that makes cheaper (but still pretty expensive) third party replacements for the Mini-Mags.It is quite entertaining to see what's inside a storage unit that RED charges tons of cash for. There actually isn't a lot. And what is there is pretty laughable if seen against their claims.If someone were to send Dave a Mini-Mag it would make for an entertaining EEVBlog episode :-)
