If you need to remove components with many pads, like connectors, it can be daunting without Low Temp Solder Wire. Chip Quik. Btw, I use acetone for cleaning PCBA's, and actually almost every day, and right now, in a professional R&amp

I built many such oscillators same way. But I used BC107 NPN, connected collector to the ground, emmiter to resistor/capacitornet. Base free. Add LED in series with such connected transistor, and you have LED blinker.

It's fun reading all that posts about dangerous caps, dangerous flyback transformers... Those fears, and your findings I can read - were/are something normal in my world. I was paid to do that. But faked technology advance, ruine

Everything went well then. I graduated without computers help - on computers. Today it's vice versa. Today every new os version - just new clicks or taps, for poor little John to make it with less clicks, and this is always presented a

Of course it isn't. I don't vote for internal combustion technology at all. Both are environmental problem. Looking at all the (ex) hype about electric cars, sometime it looks like electrics - they clean the environment... Interna

Beside all of that, if you convert let's say 1/10 of cars with internal combustion engines to electric motor cars, there is no electricity to charge them. Which also leads to envirnonmental problems - creating so much electricity

In my middle school 1983 we had similar, but with SC/MP uP, hex keyboard, 8 LED output port. We called it scamp, learning machine code and basics of architecture. Advanced students worked on a Cromemco, and we, dumbasses, we learned on

Welcome to the truth. Tires wear and all of that stays on the road, or next to the roads, seas, oceans. Years...tires... And then, we have to sort each plastic HDPE bag to save the Earth. Feel guilt if we don't. Ok that. I hope that t

Aha..just the matter of forcing obsolescence in order to raise profits in modern economy. Please excercise only on yourself, not on me. Another thing, it may be useless from your point of view. But most of the people are using phone just f

Sail boat towing other boats (similar loa) should attach towing line close to her center of effort. Think like attaching towing line to the mast foot. Not on the stern. Not an easy task to do. That's why many sailors just use any stern

Yeah, do not attempt to use. High voltage inside. Better to buy any new low voltage piece of shit. Throw this all away. Be very afraid of this old stuff. Hmmm....your Tesla, runs on 3.7V LiIon...safe.

Can you imagine perfectly stable operational amplifier made with thermionic valves (tubes), ECC81, ECC82, ECC83. Amplifying DC millivolts to stable volts and converting them to pressure 3 - 15 psi, because intrinsic safety circuits were not

No. Honeywell TDC's were in other plants - polyethylene, polystyrene. This was old olefin plant. Not any kind of control logic, no computers, no scada. Just control loops for flow, presssure, temperature on the field - with control ro

<IMHO>Pharma could go on with huge gains, just selling immunity boosters, like C, D vits, exposing to solar flares... But boosted with 'media', they were forced to take an "social" experiment. Instead, they even fo
