Missed out on a pristine Israeli FN-FAL for $600! Had the cash in hand but was unsure just what it I was looking at and bargaining for. Oh, for a second chance at life!!!

What are your thoughts about the Simulation hypothesis?

Bas

In New Jersey, the power companies have mounted solar panels on utility poles. The intelligent inverters in them are designed to correct power factor on the grid towards one from either direction. They both generate energy and optimize the grid at the same time.

Power factor question. I generate 7.6kw solar power at peak sun, but my solaredge inverter show's over 2kw of reactive power. Am I providing free correction for my local utility?

My question is: can anyone read this comment? I have reason to believe I've somehow been shadow banned on patreon!

Jeremy Impson

Are there any new cat treats at your local poundlandy type store? We've not had any China and Hutchey content in a while. (Or do we send in treat donations? :-) )

Human league which i have seen live 2019 still got it

N. Shaun Tremayne

Around '79 / '80 I got my first job in an amusement arcade fixing electromechanical pin tables. Loved it. I don't think electronics has improved gameplay at all, do you?

Steve Brace

Chinese tester first i would check on a known source. Or use a martindale safety first

N. Shaun Tremayne

Yes I worked for seiko so far away for working for Serco!!

N. Shaun Tremayne

I’m wondering if technical people like the synthesizer music (like Daft Punk). When I was young I really love Jarre Michel Jarre (unfortunately the only concert I was able to visited, in poring rain, was Destination Docklands).

Hubert Hoefsloot

What do you think of the Isle of Man under water roundabout that has been proposed this week.

Have you tried making your own LED phosphor, maybe with fluorescein? I've tried getting my hands on the commercial stuff, but no joy so far.

Jason Brinkerhoff

If you have used an appropriate gauge wire to make the repair then you should be fine. Just be aware that automotive environments can be harsh on electronics, and you may be revisiting this PCB for further work.

AlfaGuy

Pre COVID I volunteered at a local repair cafe and thought it great that there was such a good supply of third party spare parts to fix broken Dysons. But after you see as many as I did come in for repair, you think - hold on - Why is there such a strong market for Dyson spares? Because the damn things break all the time. My 20+ year old Panasonic and 10+ year old Henry are still absolutely fine.

AlfaGuy

It's going gig economy in Australia. I'm actually employed that way and I don't pay for my pension. It's the way it's going

Simon Deards VK3FSPD

Damaging spider DNA leads to horror movies

Paul Slootman

In the UK it appears that more & more companies are turning to subcontractor employment roles. So the employed person becomes responsible for pension, health, insurance and so on, also has no rights as they are self-employed. The Gig Economy. I have become part of this and it is horrible. Contrary to this my son has landed a job with a Japanese Company and they treat their employees like family. When and how has it gone so "wrong" here do you think ?

Robert

Math is the easiest way I try. This is assuming due to COVID ‘lockdown’ they have started branching out with DIY. You’re talking 240V 13A❓ that’s over 2.4 Kw 🙈 worst stuff is when they talk about burnt plastic smell running extension cords with motors long term 😭

Cerity

Thought the ozzie news thingy was Facebook not wanting to pay 4 or ABC for the links❓

Cerity

Grats on your friends 😁❤️ it’s a terrible feeling, waiting... soon enough Angie will be at 💯

Cerity

I have recently bought an electric socket tester (HT107E), mainly to check the polarity of UK extension leads plugged in via earthed adapters to sockets in my Norwegian apartment. I was more than a little surprised to see the voltage reading of 165v, rather than much closer to the 230v it's supposed to be. What could be the cause of such a voltage drop?

Stephen Pettitt

Having repaired / replaced my Dyson cordless for the third time in three years, can you strip one down and show how poorly they are put together!

Have put the below up before, might as well again. ---------------------------------------------------------- Looking for questions for this week? I have 2. 1st: This is one you might want to pose to the chat. Are there any lossleader electronics floating around on the market at the moment? It seems most have dried up due to Covid. Pre-Covid there was the "smart" speaker boom, where a number of the major players were handing out speakers at low or no cost to get people suckered into their systems. A good number always end up being sold as "new" secondhand on ebay/other marketplace, for a while they were a good way of getting speakers/enclosure/batteries + usb charging components for a lot cheaper than the parts individually. Can you ask chat if there are any good hack it to bits targets in the wild at the moment, thanks. 2nd: Trams (Trolleys in the US/Canada) typically are around 600 - 800 volts DC depending on the system (example the Manx Electric Railway is 550 V DC), and it wasn't uncommon for railways to use 1500 V DC. Up until the 1970's lighting was typically a number of incandescent bulbs in series, which were perfectly fine with this arrangement being simple resistivity loads (although if one went out, they all went out). From the 70's refits and new builds commonly had fluorescent interior lighting, what trickery did they use to get fluros working on DC? For everyone who doesn't know (Clive and many others would know this already) fluros with the correct DC voltage and drive circuitry will work but have a limited life as the mercury will all migrate to the negative end and stay there. How did they get around this? Was it as simple as using a rotary switch that swapped the polarity each time they were turned on? Something, mechanical such as a small rotary converter (motor-alternator) to make AC? Or something like a astable multivibrator (two transistors) switching a transformer to make AC (were they doing this in the '70? it would have cost $$$)? Thanks ----------------------------------------------------------

Or even designing a resistance decade pcb with a set of precision resistors that we could buy from JLCPCB

Mike Wynne

How about reverse engineering your resistance box using a 3D printed case as a project ?

What is the most interesting thing you've learned by accident? (Doesn't have to be electronics)

What components/ electronic items do you find are ridiculously cheap for what they are. For me it's the slow/ fast flash RGB LED's, and Arduino boards that seem crazy cheap for whats goes into them even going by cheapie Chinese stuff standards.

Anita Davis

Do you have any plan to reopen your online shop, even if there may be some sort of caveat regarding postage costs being higher?

Cheers request. The wife of my coworker and buddy Steve, his wife Angie got Covid and was in a medical coma for 5 weeks, but is now almost fully recovered, and should be home hopefully next week. If you could... Cheers to Steve and Angie, and great job fighting back.

Scrufdog

Firstly thanks for remembering callums whoofle. My question is what is your current recommended method of soldering smd's. Including processors and chips? Would you use an iron or rework station (hot air)?

I have one of those UVC lights with timers and motion detection like the black table top one you have but it's all on one board and I want to modify it so it can stay on for longer periods than an hour. It's in a large garage full of spiders and possibly snakes. I want to damage their DNA. Something with those led strips that are individually addressable and they come with controllers on eBay. They look interesting and I have one but not played with yet. Make some good room lights with better drivers and swap in high CRI leds and better heatsinks using eBay parts. I have made a few using adjustable speed controllers and different types of drivers. High power portable spot or flood light with a row or group of those clear spot lenses and xhp70 Cree led with adjustable brightness and lipo battery. All available on eBay. I have tons of ideas

Simon Deards VK3FSPD

Ever had the urge to completely over engineer something then hide it behind a plate? It will last for decades and someone might come across your work and give you a nod.

Olly Whitton

---------------------------------------------------------------------------------- It might be interesting to ask if any listeners that have had COVID-19 have been using a PULSE OXIMETER to monitor BLOOD OXYGEN levels and what levels did they see ---------------------------------------------------------------------------------- If you use an OZONE GENERATOR to sterilize a room, is there a good way of removing ozone from the air before you breathe it in? (Maybe activated charcoal mask?) ---------------------------------------------------------------------------------- If you feel the need to start a RANT, mention the different types of CROSS HEAD SCREWDRIVERS - Phillips, Pozidrive, Type-2, JIS, Sel-O-Fit, French Recess, ACR Phillips...... Also TAMPERPROOF screws could make for a nice rant. :) https://www.instructables.com/When-a-Phillips-is-not-a-Phillips/ ---------------------------------------------------------------------------------- What happens if you WHOOFLE HAND SANITIZER?..... could be messy and reeeely dangerous to low hanging beards? -----------------------------------------------------------------------------------

L. Brait

I bought some finest chinesium lighting. A 60w ring light. Can provide the link if you'd like. 60quid so I wasn't expecting much. Its got a generic 240v 60w driver that used to dim on a varilight pro dimmer. It's just stopped dimming. Not sure if dimmer has failed or if PSU is off. Best 60w PSU with teenie 2 pin feed to LEDs? Also was thinking of replacing the led strip with maybe a double loop to run more LEDs at lower power (the Phillips UAE LED solution) it's a good fitting well built just the led bit I imagine is cheap and will crap out so I'll start searching out the replacements now

Olly Whitton

What's the longest string of LEDs you've driven with a joule thief?

Pittsburgh Flip

Still have the lithium batteries, to try and smuggle into the Isle on Man. Is it a go?

Philip Childs

Your asking the man who thinks 12°c is hot. 😉

Simon Hopkins

Are you able to sleep properly now they're drilling a giant roundabout under the Isle of Man ?

Erwin Bierhof

FWIW I never thought much of Fluke leads. They're safe sure, but any good at zeroed continuity? NOPE. It's a specification issue. I did a stint at Megger recently and my desk neighbour brought in a set of leads they'd just tested in the high energy room. They had visible blow holes. "You should have seen them earlier, they were smoking!" I queried further and he explained these were Chinese leads but the British ones were even worse. Clearly for this test - like Fluke - they were focussing on breakdown. But that's not all that matters.

Mike Page

;-) I was looking at this. Jsut got the modules I need to try it out. I was thnking of using a H bridge motor driver with a 35v supply, initially hooked up to an arduino for testing the best frequencies, but later I reckon a cheap microcontroller would do.

Stuart Goggin

Do you have a method for sorting out your junk.... I'm a bit of a hoarder - so I have a massive workshop filled to the door with stuff... Important stuff... I wonder if there is a way you might manage that.

Stuart Goggin

A year or 2 ago, you did a couple of vids where you took blue and pink Nookie pills. Did they work? or, did anything at ll interesting happen? Curious minds want to know!

William Taylor

outer electrons insulation and how 8 or more insulate 4 to 8 semi conduct

Try clamping both the live and neutral with your 210E (My everyday driver, by the way). If there is an imbalance of 35 - 40 mA the RCB will trip. Don't just check the earth return. Lots of pseudo earths and borrowed neutrals in UK domestic wiring.

Angus McLean

United Kingdom Good evening Clive, why are Inductors different shapes and sizes and how do you measure them. Thank you, tony

Whats the state in Mainland UK in terms of Covid? In Austria they (gov.) ordered a news embargo to any other News Channel thats not the ORF, so nobody can make his/her own opinion because you only get one kind of information ( kind of scary because you normally only hear that from China/Turkey/Russia/ ect. )

Few days ago I repaired an automotive AC control module PCB that had a few broken tracks (they feel rotten, corroded) using bodge wire. The PCB worked fine. Is it safe to use the PCB this way, or I need to buy a new one? PCB just had some switches, Diodes, LEDs and a tiny transistor.

My induction hob has randomly started tripping the RCB (when it's not being used!) When idle it seems to be drawing 380 ma (measured with UT210E) - it's a plug in unit supplied with 13Amp fused plug. This seems a lot for a unit in standby. Normally no current shown in Earth lead just the 380ma through the L & N. My thoughts are some input capacitor problems but I've not opened it up yet. Any thoughts from the electrical masses?

Mr B Shepherd

Is there a way to effectively flipflop between polarities in a string of LEDs wired for flashing patterns? I have a few sets where the sexy microcontrolers are defective rendering the string basically useless.

My jaw.

Phil in the kitchen

How about: "Why do we get very good (and not cheap) multimeters supplied with absolutely shit test leads? (Possible Fluke excepted) . You pay a couple of hundred dollars for the meter and they supply Poundland test leads. If you are willing to spend the dosh on a meter with Cat IV - 600v, IP 67, actual true RMS and bundled with other features that do not include a flashlight or NCV; you probably already have good leads and probes coming out your..... (A topic of constant debate with my "significant other".) Just sell me the meter, don't make me pay for leads and probes I'm not going to use?

Angus McLean

Did you see what Dave eev blog about fuses. I find it so hard to explain to customers that they cannot run a tandem 3hp compressors off a single plug 13A. Which they have run for years melting the plug anymore. What times have you felt you are just banging your head against a wall? COVID I suppose

N. Shaun Tremayne

Did you have anything unexpectedly go bang this week?

John McFerren

I use a Imax B6 Li-Ion/Polymer Balance charger that can charge up to 6 cell battery packs in various technologies including Lifepo4. Lead acid etc. There is open source firmware hacks and upgrades to enhance their usefulness with extra features and ability to calibrate them.

Russell Couper

What do you mean? An African or European swallow?

Mike Hanley

Not sure if this is phrased correctly, if I have multiple scavanged batteries lying around at different maximum charged voltages is there a universal charging board I can get and set the voltage or does each maximum voltage require a different charging board?

Charles Underwood

What is the airspeed velocity of an unladen Swallow?

The Tinkering Shed

A couple of questions regarding your YT career, if you don't mind: - How did you come upon starting your own channel? - What is your favorite YouTube memory? - Have you ever feared for your health or life while making a video? --> Do you regret doing any video?

Hi Clive. Giving you the reminder you ask for to toast Ken Thompson and Dennis Ritchey.

Central heating efficiency. Whats better, heat one or two rooms only but having to run for longer to maintain temperature due to otherwise cold house or Heat whole house system in shorter bursts, but at a lower temperature to maintain a higher whole-house ambient temp ?
