content: Adjustable cooling is great feature actually. First of all there are old 1300W 861DE and 861DA versions with higher airflow, and they may feel too noisy when cooling. Secondly, when doing certain things, you may want to put handpiece on the stand and use it again after a few seconds, which I do very often. In such use case, quick cooling is a big detriment.

content: I've got the Quick TR1100. It works very well for removing small parts like 1206 and much smaller without blowing other parts of the board because the air flow is adjustable over a very wide range and the supplied nozzles start from 1.5 mm diameter.The only trouble is the Software.1. The touch buttons are not very responsive / difficult to use. The responsiveness is not always the same. Very annoying when you want to change the temperature from 150...380 for example.2. A loud fan keeps running for a very long time when in standby. You have to use the power switch on the back of the unit to switch it off completely which I find annoying.3. When the unit goes into standby, it can be difficult / impossible to turn the unit back on with the touch button. An option is to power cycle the unit with the switch on the back.But, there aren't many affordable options out their for hot air soldering stations with small nozzles for under 1K and apart from the problems it has saved me lot's of time.This unit under review has "conventional" buttons and might be easier to operate. I would be interested to see how the buttons respond when adjusting the air flow and temperature over a wide range.I like how this unit can also set of the office on fire by just talking to someone else.

For Soviet-era buildings, often the sole upgrade inside the apartment is replacingcork fuseswitha resettable version. Two circuits (mains outlets, ceiling lighting), no grounding in outlets, no GFCI.It’s only different for modern buildings and commercial ones (like hotels).

content: Quote from: EEVblog on April 15, 2025, 04:02:57 amI'm not sure about the "complete rebuild" part. I've heard of some people having to get switchboards brought up to current requirements, at their expense, simply in order to update the meter. And, such updates are not always customer-initiated, they can be because of electricity retailer meter replacement programs. Some people faced with this issue have been advised to change to a different retailer that has not (yet) decided to upgrade meters for all their customers, but that is probably just delaying things a bit.

So just uploaded what I shot at the time, it's UNFINISHED.Working on a way more interesting main channel video which is a design pricing analysis of this unit. And the audeince survey results showed that people don't really want to see detailed reviews of expensive high end bits of kit, so I don't see the value in finishing off the review of such a high end bit of kit. But if you want to see me finish it, leave it in the comments.

I've been building field mills for some years now.The reason why it's gold plated actually is not corrosion, as you might suspect.It is because gold (1,69V) is galvanically closest to oxygen (1,76V).So that increases the accuracy of your field mill.If designed correctly, field mills can be pretty accurate.The challenge when designing a field mill is having an instrumentation amplifier with extremely high CMRR, as jt will pick up all the 50Hz noise around you from the power lines.https://en.m.wikipedia.org/wiki/Field_mill

LolTho, I really wish I was near that bridge to experience this myself! The closest I've been to this type of thing is the Hoover Dam and it wasn't nearly as dramatic because of the EXTENSIVE grounding plane they established around the visitor facilities near the power lines leaving the power plant! I mean, 000 gauge wires bolted to the rocks running in an extensive array around the parking garage, and even the hand railing on the steps was ground strapped - taking no chances! LolP.S. - If no one beats me back there, I'll grab some pics of this all if anyone is interested the next time I'm through there sometime between now and fall 2025.

In 95 the company decided to purge the old meters, so I grabbed it and a couple of others still with fading LCDs. Loved the my bench meter so I plunked down the money and got a replacement LCD for it and it is still in tip top shape and the replacement LCD is still good some 29 years later.

(So I thought)That is a sign that the battery voltage is too low.As a result of a too low Ref. voltage, the multimeter no longer indicates the correct measured values. The display then shows ‘Lo Bat’.With the old display, only an arrow was indicated.

This is an inverting amplifier with switching the resistor in the feedback. This curcuit is also called active divider. This way the input resistance would be constant at 10 M.The active divider is quite common for the AC input in higher grade meters.

If I remember correctly, our social media manager reported it to Google and it got fixed pretty much right away.No malice or deceit, just some strange quirk of Google

content: I'm curious what the outputs of the supply board showed with the low input voltage. Assuming the others are right about accepting a wide range of input values, the outputs might have been correct. Alternatively, ignore inputting the input voltage and use power supplies to just generate the output values and bypass the board altogether to test the other parts of the system. Might help figure out how much of the whole thing is working correctly and tell you more about whether it's worth moving forward.

content: When I was still a newbie, I had some trouble grasping this. Fortunately I still remember why!I was still caught in a simple, instantenous model of the circuit.(1)If I saw a voltage source connected to a capacitor, my thinking was like that. When the voltage changes, the capacitor must instantly have the same voltage. So how is the current offset in phase?It was also not obvious, how this relates to circuits with multiple elements.Now I have a different mental model. But there must be countless novices facing similar obstacles. I doubt my younger self was unique. Mentioning this, because it’s hard to un-see and un-know things, and to recall one’s own earlier mental models. But it just happens in this case I can, so maybe it will be helpful in providing more help to beginners.(1)In fact it was a wider problem. Not knowing all these are “just” mathematical models and not “true reality.” Trapped in the naïve model too, one we build trying to interpret/explain things in familiar terms.
