As a retired professor of electrical engineering I can only sit at the feet of this wonderful natural teacher. I'm reading a biography of Kelvin and there are strong echoes of his introduction of experimental sessions in his Natural Philosophy course at Glasgow University in the 19th century. This video is marvellously clear and spoken with superb diction and a voice that should appeal to young and old alike. The economic and intellectual and practical importance of this material cannot be overstated.

Mr. Hunkin's the man I wish I lived next to growing up. I'm imagining Saturday morning finishing my breakfast and being almost unable to wait to run over to his house for that day's lesson in off-the-shelf "junk" science. I taught electronics principles in US Air Force aviation maintenance in 1982-83 using mock-ups & illustrations. Oh what I would have given for a room full of his collection of true teaching aids. The on-the-spot made nail + wire electromagnet: GENIUS; same/same for the solenoid. I'm now going to have to go back and enjoy every single video of his . . .

Thank you Tim: as a child I grew up watching your secret life series on PBS here in the states and for better or worse I am a tinkerer now because of how simple and logical you and Rex managed to break down all these seemingly complex machines. Today I am an artist who often has to make his own devices out of what's available to me and your new series is ever more educational and inspiring than the one I grew up on. I am going to make an attempt at wrangling my niece (she's 8, the same age I was back in the PBS days) to watch and be inspired the same way I was with your new videos. :-) Thank you for everything you do and I can't wait to someday visit your arcades.

I think y'all would get a real kick out of watching Mr. Louis Rossmann's videos right here on the good 'ol Utubez (KZfaq). He is a truely awesome spokesman for the US Right to Repair movement, and he often makes videos about (new) products from Apple (and several other vendors of similar but also horridly difficult to repair products) all the while ranting about the bad design while (fruitlessly) offering design corrections to the manufacturers and ways to bypass and/or fix the product for consumers. He's currently screwdriver-deep into getting the individual US States to accept new Right to Repair legislation for both consumer and farm equipment. I really think you guys would like his videos, as he seems to be exactly our crowd (judging from you guys' comments and such), and especially is you use Apple products you *really ought to* watch his stuff! cheers guys, and I hope all you lads have a wonderful day!!

"Eddies," said Ford, "in the current." "Ah," nodded Arthur, "is he. Is he." ... "What?" said Ford. "Er, who," said Arthur, "is Eddie, then, exactly, then?" Ford looked angrily at him. "Will you listen?" he snapped. "I have been listening," said Arthur, "but I'm not sure it's helped." Unlike Ford, Tim, as usual, has explained everything with exceptional clarity. I really like how he doesn’t dumb things down too much, and you come away feeling you understand how things work and can be used, but he never takes for granted the basics either. Always a good mix of the fundamentals through to the nitty gritty. And the demos and illustrations really help. For example I’d heard many explanations of how sewing machines work, but could never visualize it, until I saw The Secret Life of Sewing Machines, and the human sewing machine bit. I have no interest in the subject, but that was an enjoyable video!

@jobkneppers Жыл бұрын

Tim, thank you again and again! One tip for enhancing the force of solenoids is to use the duty cycle to calculate the on time at higher voltages. Some manufacturers mention the pulse time with the maximum voltage you can use to do so. You can dramatically change the starting force as you shown and switch to a much lower level to maintain position. I once made a beer tap with a rotating solenoid at 8 times it's 100% duty cycle for 0,1s. Worked like a charm for many years (8 x 24VDC = 192 VDC). It only took 12 Volts to maintain position during pouring the glass full. Maybe another tip; for arc suppression on dc loads an antiparallel diode works great to catch the reversed high voltage and dissipate it into heat. All the best! Job

@erikisberg3886 Жыл бұрын

You can do this in a simpleton way by using a hefty MOSFET(Nowadays very cheap) and a capacitor for the initial kick. Charge the capacitor to a fairly high voltage trough a resistor. Connect the + of the cap to the low voltage by a diode. Connect the load between D and the + capacitor. S to gnd. The limitation is the time it takes to recharge the capacitor. Worked nicely for me to extend the useful pull stroke of solenoids. Also connect a back diode over the MOSFET if not included in the package, which it most often is nowadays.

@jobkneppers Жыл бұрын

@@erikisberg3886 I did it exact like that too. Capacitor bank switched so series for the initial bang. I also limited it in time. Something like 0,1 s

This was great, Also it triggered so many memories. The first relay and solenoids I used as a kid were on my model railway layout. My first job was working for GEC General Signals designing railway fail safe relay circuits in the late 1970s. Going into the relay rooms full of massive relays was a sight to behold. I then went on to become an electronics design engineer that used all the devices you described until microprocessors became ubiquitous and high power solid state semiconductors now used in every EV. I was surprised how much I had forgotten in my now distant memories. TY.

There is one trick for young players here when using relais and solenoids, back EMF. Everything with a coil needs a flyback diode to dissipate the build up reverse high voltage when turning off the coil. For people that don't understand what I am talking about, google it.
