content: of all the topics to wander into the weeds about! farm tractors!You guys need to get an engineer from John Deere on your show. : ) sorry, I don't know any : (A 50hp - 90hp tractor is tiny. In the 1980s our field work tractors were about 75 kW  and those were smaller than some neighbors had and are not what you will find working fields today.of course everything is relative. Tractors are 'heavy' and 'powerful' from my point of view. Here are some main points.- Tractors have Diesel engines and these are good for delivering a flat torque curve vs RPM.- of course the gearing is for relatively low speed. Our highest road speed was probably 20 mph [32 kph] but today's tractors have higher road speeds.- Tractors can probably do near 100% duty cycle. The 100hp rated tractor might pull near that all day long when pulling a chisel plow, for example. You might compare this to the hp rating of a car engine - but the 200hp car will only reach that for a freeway pass burst and normally use much much less going down the road. I don't know the regulations about the hp rating on cars but it just seems you are not going to be able to load a Honda car engine to 200hp all day long.The weight of a tractor is important so I am just guessing a battery powered tractor would be a bit of a challenge. Tractors are heavy to the extent they need to do the job without breaking the frame but past some point there is an issue of compacting the crop soil too much. That is why some tractors have tracks to distribute the weight over more area.here is one that is 346kW ratedhttps://www.deere.com/en/tractors/4wd-track-tractors/9rt-470/It would consume the energy in a Tesla car battery in less than an hour - as fast as 17 minutes or more likely about 1 hour since many tasks don't use full load continuously. With a more modest row crop tractor maybe you would get 1.5 hours which of course is nothing compared to the required work day.The topic of electronics on ag equipment is an interesting one, I don't know a ton about that but I know our family's 70-80's vintage tractors barely need electricity and they are still useful today, if a bit small for a real farm. The battery is there for the starter, the lights and the radio.cheers!MarkPSI grew up on a small dairy farm in Wisconsin USA, hundreds of engineers of my generation were raised this way and most of these small dairy farms are now gone and the land switched to cash crops or merged to bigger dairies doing things a totally different way.The main tractor on our family dairy farm was a 2940 John Deere, we used it for so many things. It was purchased in the very early 80's as new and it is still on our farm today, no worse for the wear. Diesel tractors are very simple and robust and just last.

content: Dave asked, who's using PLC's?Back in the 90's/2000's I did a lot of PLC programming using Mitsubushi System-Q/Q-Series PLC's & IEC Developer software. This wasn't ladder logic (but you could still write it), it was more graphical.Really nice to use, you designed or used existing blocks and tied them together. You could still go online with IEC and see all your live data.I played with Siemens, Allen-Bradley and Toshiba PLC's a little.........but no comparison IMHO!This is IEC Developer:-

content: Yeah, these days most development environments for industrial PLC supports the IEC-61131 standard which in turns defines a couple of different "languages" that can be used,Ladder Diagrambeing ONE of them. TheIECinGX IEC Developerthat Ian shows a screenshot from comes from the fact that tool is IEC-61131 compatible where the older version, simply calledGX developerwas not. Today I think their (Mitsubishis) recommended tool is GXWorks3.I'd say that for anything but the most basic projects you end up using a mix of the different "languages". Dave mentions a state machine for example, that's pretty much what SFC is, you don't need to do an FSM using discrete ladder logic.Anyway, yes Ladder Diagram is definitely used each and every day but its "definition" might have changed a bit since the 70's. It's not just contacts and coils. In fact, what Ian shows IS Ladder Diagram (as shown by the  designator next to the POU (Program Organization Unit) name in the project tree)

But beside it, it says NAND. So I think NAND has some issues, but I am hoping it does not effect anything and is a bit slower. I preferred a larger OS partition so I could install all sorts of stuff to the openwrt. I use it to do things like yt-dlp all night with my cell phone. Works fine. Like I set up to get a load of youtubes or a movie and it is on a flashstick when I wake up.https://openwrt.org/docs/techref/flash

For this I am using an Audigy 2 and the KX Project 3rd party drivers. Using this setup requires a PCI slot on your motherboard, as well as the card. I think in theory you can use it for some inline DSP using sources and outputs.I have different dsp layouts you can load, and one had a compressor that basically made a TV all the same volume no matter what was going on with it so it would not be annoying at one point.

However, I don't see why you'd want to lower the lifespan of your car for the pennies back you may get for making the city's power grid more efficient. Also, you want your car charged when you want to use it. So this whole line or reasoning is sort of silly, except you would have house power during a blackout with the same hardware.

content: @00:42:28, Dave saysYou can be an electronics design engineer, go your entire career without solving an integral or without going back to basic physics.Unfortunately that's not true. At least not for Dave. If he calculated the battery capacity he needed for a reasonable battery life for his 121GW multimeter, he solved an integral.bc(t) = battery capacityi(t) = current consumptionbc(t) =0ʃti(t)dtIf you consider i(t) as a constant (I) and you target a certain battery life BL, then:bc(BL) =0ʃBLIdt = I0ʃBLdt = I × BLbc(BL) = I × BLCalculus was first invented by Isaac Newton but first publicly proposed by Gottfried Leibniz as a rigorous mathematical description of the physical phenomena they were studying. They didn't do it for the fun of the intellectual exercise. What they offered was an invaluable tool for the prediction of movement of physical bodies and our modern engineering is all based on that new concept. From the times of Newton and Leibniz to our days, calculus has advanced a great deal.When you go for your degree you're looking for the advanced topics of engineering and accreditation as a professional. And that's exactly what they do. They show you how deep the rabbit hole goes.Maybe you can spend your whole career in engineering design solving simple integrals that you don't even recognize as such or using trivial physics concepts, but the fact is that calculus and physics are unavoidable. And since you really can't tell what your career goes to show, if you're not prepared may miss opportunities.So we lend a disservice to engineering education when we disparage the study of math and physics. They require rigorous thinking, and that's all for the benefit of engineering. Instead of discouraging people to study them, we need to explain why they're important, and why they're required if you want to be a full-fledged professional.

content: Dave, I was listening at the podcast in the car and heard you mentioning that the stencil dispensers are slow - there are new much faster solder paste dispensers being available for the past ~8 years. They are different from the technology you are thinking (e.g. the Martin machine you have filmed at Altium). These new machines use a jetting valve, which allow them to dispense smaller drops (if needed), precise in volume measurement, dispensing very faster and when combined with fast x/y gantry it turns into quite useful machine for some assembly floors. The machines are quite suitable for situations where high mix low volume boards are assembled, so no need for stencil storage area, no need for stencil washing machines, faster changeover b/w jobs.The cost of these machines vary b/w I would say 20-40k for small bench top units/integrated units to PnP machines to ~500k for large standalone machines. One thing to note here is that the jetting valves require changing after a number of operating cycles (drops) and the cost for the valve alone I think starts at ~10k for the main brands out there.Still, there are situations where the old stencil can be more economical and faster, such as on assembly lines with high throughput, large boards and that only few boards are being assembled.

They are too busy trying to get emissions down; we went in 10 years to .2% of the original emissions - now they want to spend enormous money to halve that .2 to .1%, meanwhile ignoring the fact thata) most greenhouse gas emissions come from coal/gas power plants - sorry Greenpeace, the only remotely clean power source we have is nuclearb) there is no real restriction (as Dave said) on emissions for huge ships, they don't have to do much aftertreatment of exhaust (some US ports have restrictions)c) there is absolutely no emissions limits if the engine is not used to power the car"C" is really funny, actually. This way Berlin could replace 15 regular diesel buses with full EV buses (yaay) that don't have enough juice to power the HVAC system, so in comes a little 4cyl diesel enginewithout any exhaust treatment- making the EVs much more polluting than even the modern diesel coaches (I nearly got a nosebleed when I found this out)"A" now we only could get those molten salt reactors up so we could burn up all those higly radioactive waste we now bury like a cat does its s**t - also as Germany is slowly finding out, solar panels, if you add ALL the costs up, including recycling the panels after EOL, might be a net powerloser.

But of course a lot depends on what your interests are, and where your expertise lies. I have almost none of the latter, so it's all good.We'll miss you. Let us know if you find something better.

content: Greetings, electron steering folkI am very much enjoying"The Amp Hour"podcasts, notably:> The Vincent Himpe episodehttps://theamphour.com/169-an-interview-with-vincent-himpe-escaped-electron-elocution> The Forrest Mims episodehttps://theamphour.com/171-an-interview-with-forrest-mims-snell-solisequious-scientist> The CREE LED episodehttps://theamphour.com/the-amp-hour-71-luciferous-led-lucubratorI very much enjoy old timer stories of yore, with the exceptions (not always) being:> I find anything related to/leading to "retro" computing/Apple/Silicon Valley etc, rather stale and "meh" - it's just that there is SO much repetition of these stories, and so many digital consumer computing history stories around, I can find that noise anywhere, and am tired of it. Example - Woz - he's amazing, but I've heard his stories a gazillion times, and as for Steve Jobs... yawn...I like things I can relate to - old tales of factories and workplaces (like the Vincent Himpe episode with the silicon fab tales), preferably non-consumer gear - a good story telling guest is a plus. Oh, and yeah - you may notice I am not picky, heh! Anything unusual, takes from greybeards and nothing related TOO much to software and processors - preferably analogue stories or stories from factories, development.... I am finding it hard to PRECISELY quantify the mood of what I like, but it's 50s-90s kinda quirky stories that go ON AND ON... the longer the podcast (3 hours+ is better, the longer the better.)Definitely NOT interested in:"Gaming""Raspberry Poo""Open Source" or software hippie stuff, CRINGE.Anything of that ilk, regurgitated too often online.I am interested most in the simple stuff, how components are made, tested, invented - funny stories, how the paths of life of the guest take unexpected turns, industrial/military/silicon fab/inventions... etc etc...If you can recommend any episodes based on this somewhat obscure criteria, I am indebted to you.Shalom.

However, I find most guests (including those three!) have something interesting to add on the state and/or history of the industry.Open minded listening leads to unexpected nuggets.YMMVrt

content: Hello!Was a nice episode to listen, still great to hear you both on nice subjects.Anyway I was boiling in my car listening about the Tesla Powerwall internet connection.Yeah sure it raises security issue, but I really believe on the interest to get such device permanently connected.In short summary : smartgrid #rev3 @jeremy_rifkin or the decentralised internet of energyOk the 3rd industrial revolution can be debate, but it gives you an example of the interest of interconnected energy storage and usage.Knowing who where, energy is stored, generated or used is a vital key feature for energy usage in our changing world, climate change, etc...So it is very relevant for Tesla on a system point of view, to get data from their solarcities and powerwall to offer services of "stable" (or trying to...) renewable energy delivery.As an electric car can be also considered as an energy storage (filtering capacitor system wide) when not used and connected to your house solar panels.As having permanently connected autonomous cars. Just don't see automous cars as individual cars, but as a system flow that could allow making more efficient road (car/hours) if their speed and paths are thinked as a fleet.Yeah, connected batteries and cars offers security issues, but that's a trade off with the services it could offers.And I agree with you on the other concerns, problems and solution for the overall IoT and security concerns around it.See you!

content: This discussion reminded me about what happened to me when I was that age. I recall reading a book called "Listen to the Leaders in Engineering" and that led me thinking of going in that direction. I had in interest as I built electronic kits and had a Ham Radio license in Junior High (6th grade or so) However, my folks actually discouraged me from that direction (engineers don't make good money) and pointed me in the direction of my other interest, the financial markets. So what happened, I went to a top University program in Finance/Accounting worked in that field for three years and ended up returning to school for a Masters in Computer Science. I've been working as a software person (QA for a few years, for the past 20 odd years development.) Recent interest in IoT has refired up my interest in the hardware side and I've been enjoying the Amp Hour podcasts and David's videos.

content: Would be interesting to see Daves approach in these games, they do feel like designing a device.Only thing is that these zatchtronics games usualy need to get a few hours in to figure out the game mechanics before you get to the interesting engineering solutions. First levels tend to be a tutorial and example of how certain parts work Just like you fist have to learn how to light up a LED with a battery, how to use a transistor, how RC circuits work etc... before you can be be tasked to design a circuit for blinking LEDs in a certain pattern.Actually if a zatchtronics-ish game used a real circuit simulator as part of its game engine it could make a excellent educational game for teaching people electronics. Basically take a circuit simulator, add goal conditions, add parts restrictions, introduce gradual unlocking of more parts to avoid being overwhelming. introduce a scoring system, make a bunch of levels and there you go.

content: The old radioisotope generators used Seebecke effect, thus units similar to the peltier modules for cooling. However there is new research to use the IR radiation form a source running much hotter and get there energy this way. They hope to get a better efficiency this way. So there are two different concepts that work. AFAIK the ones used in space flight are still the old thermoelectric ones. The IR radiation method is likely not working well on small scale.The Pu-238 used for the space flights is different from that used in weapons or nuclear power plants. It needs a completely different path of production to get it in sufficient purity. Still restarting production is easier than going to mars, though is needs an active nuclear reactor.Helium does not freeze from just cooling (it only does it under pressure). Also there is no way the oxygen could get so could it would even liquefy helium. Oxygen is solid well before helium gets liquid. Chances are more the other way around, that too cold helium could cause some of the oxygen to freeze. A known trouble with liquid helium containers is the outlet to freeze shut (e.g. from humidity) and than cause excessive helium pressure up to an explosion.
