The trashiest electronic channel on KZread. We test and use affordable electronic soldering equipment and tools to build, teardown, modify (and sometimes destroy) random electronic stuff.
A British TV licence is NOT required to view my videos or almost every other video on KZread.
Many of the builds and projects featured here operate at full mains voltage and carry a high risk of shock and fire. As such they're really intended for either entertainment value or for those who do similar stuff.
The videos are generally uncensored and may contain tasteless jokes, profanities and even blood and electric shocks when things go wrong. So just like a normal workshop really.
So kick back, grab a beer and enjoy the ride.

Almost make a good controller for 3 light circuits in chase mode
OMG LOL, I have done that too many times. 220 / 220 =1. 1 x 220 = 220. I knew I could do it in my head, but there's a calculator right here!
A friend of mine was killed attempting this….
oh those neons, wow
But my own battery doesn't last. What can I do. Once I one the it goes off in 15 minutes
I thought it was quite interesting that after you repeatedly rubbed that long IR line how it rose up afterwards. Are you sure that this is for controlling "fans"? I mean, I can definitely think of devices you might want to change the speed on automatically at short and repeating intervals. Did you check to see if "lights on" or "lights off" was the default? Everyone has their preferences.
In paper from the butcher shop.
Why would this need a capacitor?
That the model number😮😅
Safe tho?
The East Asians love their Posidrives. Most rising clamp terminals are cross- and straight-friendly, but for the _less_ friendly ones Posidrive is where it's at.
Hi, what would you recommend as a MOSFET replacement for the SS8050 to control the brightness of a 5V COB LED strip? The strip uses about 600mA when powered directly, and under 20mA when PWM=255 from a PIC mcu. I found out linear PWM is not really a good option cause there's lots of "random blinking" and the LED never really shuts OFF even at PWM=0.
If the existing transistor is a bipolar one then the use of a MOSFET may depend on the existing circuitry. The classic one used in many Chinese products is the A2SHB. It may at least need a gate pulldown resistor to the 0V rail.
WEIRD SENSOR OUTPUT: On a box store portable dehumidifier: Output is 30% all the time. Exhale on the sensor and humidity spikes to about 90%, then for about 30 seconds, slowly decreases to 80%, then stays constant at 80% for about a minute, then display goes from 80 to 30 or 31% instantly and then stays there forever. I think something cracked on the sensor (unit is 12 years old), it's open but under high humidity it "conducts" and produces output. I think the controller has a min display value of 30% no matter how much lower the actual humidity is. What do you think?
I just like being able to see. Never once gave it a thought. I have 4 different blubs in my lamp
Jars. Wilkingers are far superior to ANY Ye Olde Oak hotdogs
This could make a nice little remote & PWM controller for my home built used oil burner. One for the constant on fan, pulsed oil valve for low and constant on for high fire. Pulse on/off control of the spring closed powered open valve would act as a pwm. Hummmm
The most vile bottle of whiskey on the planet🤢🤮🤢🤮🤢🤮
How long would that battery last if you could get 98KW out of it?
Science is painful .
"and bring in the 1st exhibition" @ 4.17...really makes it feel criminal LOL 👉😵👈👉💎👈❗❗❗
That would be 2 shillings and 6 pennce in old money? Can I start a biding war at 10p?
Nice
Its quite possible it was created for that reason. Zap the people that dont know how to plug things together correctly
Fans only need two modes: Off, and Shred.
In the USA its mostly plastic vac packs
I have tried Aldi knackwurst in jars and plastic shrink-wrapped from the meat section. I found the jar version inferior, I think due to the water in the jar sucking out all the flavour.
Thank you, keep working.

Yes... Yes... This is why I'm here... Carnage. Peel that metal flesh Mmm crumples
These were.huge in the late 70s and early 80s
Welder Goggles, please! 😊
That Fireball is bad. Too much sugar. Sure fire way to have a terrible hangover
Do you think god stays in heaven because he too lives in fear of what he's created?
I would make my sand picture, but replace it with some wierd stuff like rotten meat, Bovril and other crap; then I can watch it decay and go manky. It would be sealed up. I did an experiment where I had a rotten piece of bacon in a tank and left it to go off for a month, and it was yellow after that! I liked doing experiments like that. Shaking shampoo bottles after putting salt in it or whatever! I have done some really nasty science experiments for fun over the years, like trying to create the nastiest smell possible for instance.
You are not at all what I imagined but I am not disappointed.
Wow, you don't wanna see my anus; not even in the middle of the coldest winter's night, sitting on a metal tiolet seat!
The ramp mode would look good controlling a traffic light.
It can work, but you need a vessel that can handle more pressure
Your ability to read chinglish as fluently as reading correct english is a pure talent in itself! 😎👍
"And I shall focus down a little bit... On to... The burnt squiggly line." *This* is how you control fans; by giving them exactly what they want!
i think it's typo and should be 98000 centymiliWatts
They could have gotten away without the diode on the input. (The one that goes to +5V) Replace it with a 5.1V zener and forgett about the zener on the right side (basicaly swap the zener to the left) That is penny pinching to the max, but you can use a zener diode as an actual diode and save one BOM item. on the positive half wave the zener conducts forward with 0.6v providing a return path for the capacitor on the negative half wave the zener conducts in reverse at 5.1v. Minus the diode drop of the diode at the top, thats 4.5v for the rest of the circuit
It's out....
