content: Kathy Loves Physics channel is amazing. When I discovered it, around the same time as Dave, I binge watched it. And I was pleased to see Dave's comments there.I got interested in the history of science when I first got into contact with Thomas Kuhn's work (the guy of the paradigm shift). I'm currently reading his "Black-Body Theory and the Quantum Discontinuity, 1894–1912" and I recently devoured (metaphorically speaking) "The Maxwellians" by Bruce J. Hunt.

content: At least for the lower frequencies one can get a bit more amplitude (an extra 6dB) if one skips on the 50 ohm termination. It gets a bit dubious later on.An amplifier with only a gain of 4 makes some sense. 4 V may be still just OK for the internal 50 Ohm terminations, though the program calls for 3.5 V max.Part of the common mode gain could depend on the exact twisting / position of the cables. So ideally one should repeat the measurement a few times with different cable positions.

content: Our situation has not improved, so why is it 8dB out of spec there at 20 kHz?Printed circuit board "hook" will cause that in high impedance circuits. It means that they did not use the right type of printed circuit board material, and its dielectric constant versus frequency at low frequencies changed after testing or design. One of my older posts includes an article about "hook".This is why before "hook" was understood, Tektronix built their high impedance circuits on special board materials like polysulfone. FR4 type board materials must be qualified for high impedance low frequency applications.

content: At the bottom there is the symbol indicating that these shoudl not go to the normal waste. Having the LI battery is one good reason for this. Should also no to to the normal E-waste without removing the battery.The Kalman filter is nothing that special. Much is just about the rules used to generate the filter - usually a system with some redundency in the sensors and thus the need to correct the errors of one sensor from another sensor. E.g. one may be drifting and the other is noisy. The final filter that comes out, may not be something special.There are quite a lot of IR reseivers - they look a lot like those for IR remotes in TV etc. Chances are they are used to find the charging station from some IR send of the charging station.

You watched enough of movies to know that e.g. zombie hands can still assault humans after the body is destroyed. Worst of all, you probably packed them in one of those metal cans and placed next to the couch feet. Not only the wheels can now learn about human behavior from the couch feet, but they can roam freely in the bunker and conspire with other electronics you store there! Incredible, how easily a human is deceived by machines.

Can I directly connect +2.5v and -2.5V without battery ?2. Should I connect the negative (DC_VOUT-) to the ground of the board ?3. Is this correct way of measuring positive and negative voltages, If this is the case Micro cannot take voltages less than 0V, is there a way around it ?I would appreciate it if you could answer these questions.

content: Maxim did quite a lot ADC chips for the early DMMs (ICL71xx variants). Chances are they were 2nd source for intersil and they also had some extra ones for higher resolution. They also have newer ones, including some based on sigma-delta.Because of the age I doubt this would be a sigma delta, more like a dual slope or kind of simple multi-slope (like the old LD120 and related). For a classic dual slope I am missing the usually relatively bulky integration cap (e.g. 100-500 nF PP type). There are 3 foil capacitors around, but they look a bit small for an ICL7135 or similar, clould still work for a faster running one (e.g. similar to max132) to get a fast bar graph.The relays in the DMM are likely for the current ranges, maybe for the highest voltage (e.g. >200 V). Chances are the set of diodes and transistors are for driving the coils for the relays.

content: First up a massive thanks to Dave for so many fun to watch videos!I really like the way everything is pulled apart technically and the fact that it's done in a quite outspoken manner.During the weekend I've been watching Dave pull apart kickstarter campaigns and well done because I agree that there is a lot of BS out there from people who have no idea about what they're doing. Unfortunately in business I have found that many people are like that because they are business people first and the "engineering position" is just a role or job.I also checked out a few gear reviews too as I'm in the market for a multimeter having not used one for 20 years since my undergrad days - I created a topic thread on it anyway and now I'm weighing up between Brymen and Hioki. I love the Gossens and of course Flukes are Flukes but for a personal meter do I need to spend more for the paper trail.... thanks to everyone that contributed and helped out, it really is appreciatedIf only the EEVBlog could be broadcast on TV and have it's own radio station. Really enjoying things a lot.The Solus vblog was just too funny, guess they're trying to compare a standard heater to an incandescent light bulb while having thie magical thermal paste turn the radiator into an LED - sigh.I am envious of Dave though with so much kit and gear to play with. It's just a lot of funWell, time to enjoy what's left of the weekend, maybe with a few more EEVBlog videosIt's almost like watching the Dilbert episode when the doctor tells the Dil mom that he's gona become an engineer after he rewires the microwave and turns it into an X-Ray machineI wonder if it's worth trying to build a kickstater with the product of a "Time Machine"? Dave could take the project lead on it, as long as there's coffee involved I'd be happy to participateAnyway, this post was more about saying thanks then anything specific

Episode #168 How to set up an electronics lab - Oscilloscope for old PCs - Page 1
Forum section: electronics / general

timestamp: November 04, 2022, 11:56:09 am
content: Hi all,I need your opinion on buying my first oscilloscope for my lab. I am a hobbyist repairing old PCs (386sx - 286 - 8088 etc) and so far, I am doing well with just my soldering station and my D.Multimeter that can measure also frequency up to 40MHz (just measurement, no sin wave forms or any graphics).Unfortunately, I need to check my old PS/2 386sx-20 that went rogue and when I probe the clock freq. pad of the processor I read just KHz...Is it because the actual frequency coming from the crystal is out of range? Obviously, it is time to buy an oscilloscope and the budget is really tight.---- Question to the forum -----What is the minimum Analog MHz BW that my first oscilloscope should have to get meaningful readings on crystal oscillators and data buses of old 16-32bit machines? Can I do something with a 20MHz dirty cheap analog oscilloscope?Thank you all for your patience ...

author: Kleinstein
author_rank: Super Contributor
timestamp: November 04, 2022, 12:13:10 pm
content: A 20 MHz scope can be used for a few tasks, like checking the signal levels in the old ISA bus, but it is too slow to check for issues with ringing and similar. It takes more like a 50-100 MHz scope to see such issue. With not well repetitive signals it would help to have a DSO or at least an analog scope with a delay line to actually see the transition you trigger on.Some care with old DSOs - some of the older hybrid ones that offer and analog mode are slower in digital mode. Another point is using equivalent time sampling. Both effects can be an isse with non periodic signals, like often found on data / adress busses.

The "bandwidth" of an oscilloscope isn't only indirectly related to the frequency of the clock signal you're viewing.To see a clock signal well you need a 'scope with bandwidth something like three times the frequency of the clock signal. I'd say something like 50Mhz bandwidth would be the minimum you should look for.

At least that was the case when YT just introduced that feature as an incentive to attract them away from TikTok.The bright side is that they are almost the epitome of bullshit trendy crap, and they are a decent way of witnessing how low at least part of our society has sunk.

I wonder if he'll take it on?(I doubt it. He only seems to do the low-hanging fruit lately and that one doesn't look very pickable to me. Apart from all the false gates that will bind the levers in place, it looks like they've made it very, very difficult to tension)

No, no he can't.QuoteIt's a high security safe lock, that's what you expect. The Cablox one would be easier than the Ross 700, but you'd still need the dedicated tool I think.Someone in the comments pointed out 4 different LPL videos were he has picked these lever locks. I checked and they weren't even close, and he had to use the specialised tool.

content: The TP5400 is a charger and boost circuit to produce 5V from a single li-ion cell. But perhaps you don't need the inductor if you aren't using the boost feature.Also, there's something going on next to the battery connector (where the FNIRSI logo is). Perhaps that's a DC-DC converter?The half-price thing is, of course, just a marketing gimmick.

content: I know Dave had input in the 121GW, but I was specifically wondering if Dave specified protection features, or connector type, etc...Watching this, and I am not sure I saw it or not already, it seemed to me that Dave confined the physical details as well as functional details of this? It sounds like there was a sort of freedom by the manufacturer to lay out the boards and parts beyond the micro? I was just wondering, because in a positive relationship with the manufacturer, there is just a set of specifications and a price and it gets done. In a more unsuccessful outcome, the client could endlessly try to revise things, or the costs could get out of whack with the product. Also the manufacturer has to succeed in building the objective. Seems to have worked out?

content: Even those are not useless. In some scenarios the threat model is limited to things like money having weird tendency to stick to worker’s hands. A simple metal case or a box like that is enough to deter most of such opportunistic attempts.The problem is that they are advertised as if they were high-security devices, deceiving buyers. That’s on a verge of being a scam.
