Thank you so much for your detail explanation. I learnt from you a lot, I mean it.
You're very welcome! I'm always happy if my videos are useful to somebody.
If it's too hot for sailing, then go whaling.
The largest "whales" in the area are about 20kg and harpooning is not allowed 😅
Promises, promises...will the weather be cooler next week?🌞🔥🤣
Next week the temperatures should be down to a manageable 25°C. So I'm optimistic. The last few days it was 30°C or more, which amongst other things led to a thermal shutdown of my studio lighting (and my brain) - my lair is under the roof.
Спасибо за видео, сегодня получил такой и уже починил😅
Пожалуйста! Что с тобой не так? И как ты это исправил?
@@robertssmorgasbord в моем случае при сборке повредили компоненты на плате. Я починил. Мой прибор немного отличается от вашего.
@@Aaa-mx4ft Благодарю вас за информацию!
You have FAKE CHIP.If your serial number is A50285BI or 00000000 you have fake chip. You have "custom' fake chip :)
Well, that explains why it doesn't behave in all respects like an original FTDI chip (like shown in the video) 🙂
Displayport is AC coupled at the source, so additional ac coupling caps arent needed at the converter. In fact, one of the key uses of this chip is to convert displayports ac coupled serdes into a dc coupled tdms signal. Secondly, strictly speaking this is to enable a dual-mode displayport connector to output to dvi, as true displayport signalling is actually packet based, and can run on anywhere from 1 to 4 lanes in differing applications.
As usb- c displayport alt mode doesn't support dual mode, usb-c to dvi adapters actually have protocol conversion built in.
Thanks for the info! I'm to hung up on the electrical side of those things (level shifting etc.) to deep dive into the higher protocol layers 😅 So, thanks again for providing that info!
@@varno Again, thanks for the info! USB C isn't even on my radar as a display interface 😅 But of course it's one of its functions.
Excellent presentation Robert!
Thank you very much!
Hello Robert, I am a little bit confused... Is there a difference between RS422 seen as communication protocol and electrical interface? Because I am considering an encoder line driver 5V Rs422 and I don't understand what the RS422 means in this case. I think it just means that we have a differential conversion in rs422 differential signal. Is it corrrect?
RS422 is a physical specification for transmitting/receiving asynchronous serial data (differential signaling, signal levels etc.). RS422 doesn't care about the logical format of the serial data transmitted (e.g. 7 data bits, no parity bits two stop bits - or - 8 data bits, parity bit, one stop bit). You could transfer the same serial data via RS232, RS422, etc.. Hope that clarifies things.
@@robertssmorgasbord Sorry just another question, if I have a signal A that can be 0v or 5v, with RS422 I will have for A=5V -> A+=5V and A-=0V and for A=0V -> A+=0V and A-=5V or if A=5V -> A+=2.5V and A-=-2.5V and for A=0V -> A+=0.epsilon V and A-=-0.epsilon. Or they could be both good solution? Thank you.
@@LucaniaRobotics As far as I can tell your first example (0V/5V) is well within the RS422 specification. However, +/- 0.epsilon V wouldn't work (e.g. +/- 0.9V), because the minimum differential voltage (Vod) under load is +/-2V. +/-1V is in that case the minimum on the signal lines under load.
Hi Robert, thanks for the info on the calibration. I downloaded your code for compass but at North I have the 0 degrees but then I get -1, -2 etc.. on South it stop at 179 then I get -179, -178, -177 etc.
To be honest, I have no idea what's going wrong. BTW it's not my code 😅 if you want to have a look at my code have a look at "The Details" videos about that chip (first one here ruclips.net/video/NTDS2Vmnr-4/видео.htmlsi=hib-w7Kg9msAigIU ).
Hi robert Thank you very much for the video its reallay give me a lot of new knowlade. i have a questions about the thermocouple with the max6675,now im in a project to make deep frying machine and i've used the thermocouple. everytimes the themocouple touching the survaces of this machine which is made by stainless steel its get failure for the thermocouple read the temperature. i hope you have any sugest or recommendations for it, should i do special methode for this thermocouple max6675 or i must to use other module for it? thanks, have a nice day
You're probably experience a problem related to the shorting issue I discussed in the video ( ruclips.net/video/qub3yzqEwek/видео.html ). I guess in your case the power supply of your microcontroller and MAX6675 has some (albeit small) potential to the housing / the stainless steel of your machine. This causes a current loop through the sensor into the MAX6675 which messes up the measurements. There are three possible solutions for that problem: 1) Make sure your MCU and MAX6675 are galvanically isolated from the housing of the machine. 2) Use an isolated thermocouple. 3) Galvanically isolate the MAX667 (see ruclips.net/video/6rEJh4yPekg/видео.htmlsi=7D7Fo1dMdy6NBIwd ).
Great video , thank you very much!
Thanks for the praise! And you're very welcome!
I love your editing style, so entertaining 😂
Thanks!
Hello i have the same hard drive i was wondering how do i recover data from it , because my pc sadly isnt functionable, will this destroy it ???
Well what I did to the drive certainly destroyed it. What exactly is wrong with your drive? It doesn't spin up anymore? The computer doesn't recognize it anymore?
Awesome ! this guy looks fascinating, I look forward to more detail and I know it will be complete !.....cheers.
I just uploaded a little teardown, because I need(ed) some time to think how to tackle that chip. But I think I've go a basic idea now.
yay
Yeah! We're back to interesting chips and coding 🙂
Hi, silly question, for the probes where the gnd must be connected? I can connecto between T2 and T1?
Again, no such thing as a silly question 😉 In that video I connected the oscilloscope probes just across the load (see red arrows here: ruclips.net/video/rLpFtSayZ3Q/видео.htmlsi=H_jZpEFONajM_lWA&t=1988 ). It doesn't matter which way around, since we're measuring AC. WARNING: You're oscilloscope ground is usually connected to the AC mains ground. So without galvanically isolation your circuit (I'm using a transformer here), you might create a short and create a big bang!
Hi, silly question, for the probes where the gnd must be connected?🙈
There's no thing like a stupid question 😉 All probes were referenced (ground connect to) MT1.
Awesome quality video , Robert Sir !!
Thank you very much 🙂
I saw another RUclipsr using paint thinner 647 with good results, the thinner dissolves the toner ink when wet and it covers up the small gaps as it dries up. Should be way cheaper than the spray.
Well, that RUclipsr you mentioned might be on to something. 647 contains butyl acetate, ethyl cellulose, acetone, butyl alcohol and toluene. It seems to be a secret what's in the density spray. 400ml of the density spray are about 10€, 5l of 647 are about 15€, so there's that. However, 647 seems not to be available in Germany (too toxic?).
grateful i saw this video before i took apart my WD passport. can't use the harddisk for what i want other than an external. the idea was to bang it in a xbox 360 harddisk housing as they're sata and this thing isn't, what a shame. didn't know that socket was integrated, never seen that config before. again, thanks for this video, saved me a tonne of headache.
You're welcome! There is the theory that western digital makes direct USB hard drives, so they can sell the SATA version at a higher price. But then, maybe they really just want to build their external drives as small as possible. Who knows.
@@robertssmorgasbord stands to reason either way. there's probably an intermediary circuit that converts to sata out there (or will be) not sure what it would be called as searching hasn't turned up anything.
@@amiga12001 I've searched high and low for an adapter/bridge that would connect a USB disk to a SATA port on a mainboard, but I was never able to find one 🙁

@@robertssmorgasbord Its the intonations too. I mean yes, i saw that you dont look like him, but you sound so similar its funny. Maybe that really is just how Germans tend to speak, i dont know
@@karyjas1 Well, not all Germans have that intonation. It depends on the area. That guy currently resides in Essen and has probably been raised in that area. I was born in Düsseldorf, just 30km from Essen.
Sir, first of all thanks a lot for the video. Iam making a similar temp Data acquisition system with arduino. I have to measure 2.5m underwater. Should i use a thermocouple or thermistor? Please reply.
OK, when to use a thermocouple or a thermistor basically comes down to the temperature range you want to measure. Since you're talking about 2.5m under water, I guess you're measuring "normal" water temperatures between 0°C and a few dozen °C. Thermocouples a great for measuring very high temperatures (hundreds °C), but that's not really necessary in your application. So I would go with a thermistor. Anyway, if it fits your application you should consider using a digital sensor like the DS18B20/DS18S20 ( ruclips.net/video/XUm9RPWRBx8/видео.htmlsi=rNz_LZVcwO_D3_HV ). Here I'm using one to measure the temperature of a water bath: ruclips.net/video/EP1Lc-g3uY0/видео.htmlsi=2YE7tQAADdcGYFHu .
Compliment for very portano tutorial , could you inform me about spring regulation?
Thanks! The spring is contained in the cylindrical housing beside the large black knob (left in the screen here: ruclips.net/video/dGyBfAovh6o/видео.htmlsi=slgBMNotiL8JY2wg&t=1325 ). It's just a long flat piece of spring steel rolled up in that housing. To be honest, I didn't dare to open it up, because the spring is rolled up in there with some force. I guess you could increase the spring force by rolling it up some more, respectively, reduce the spring force by unrolling it.
thank for your answer best regards iller
@@illergiuliotti1896 You're welcome!
Is there a particular reason you used copper to make the capacitor? For liquid sensing purposes, is this the best choice, and why? Thanks so much, your videos have been very helpful.
I used copper because I had a roll of thin copper sheet at hand. In this application the material, as long as it is a reasonably good conductor, really doesn't matter. You could use a carbon/graphite film if you wanted.
This is great info; I wish I had found it first. After following other tutorials I have run into all of the problems and dead ends that you illustrate. I could have saved days! I'm making a sawtooth wave and would like 4096 steps in 1 to 10 ms. I've since realized that this won't happen, but after going from a Nano, to an ESP32-C6 to a Teensy 4.1, I have updates every 4.5 us (MCP4921, 1 channel). I'll have to slow that down a bit for reliability. The output using the Teensy looks awful when zoomed in to the levels you used. I'm looking at filtering, bypassing, and lowering the slew rate on the Teensy output but so far nothing works.
Thanks for the praise! I'm happy if my videos are actually helpful to somebody.
Could you please help me. I can also send you the picture of the circuit and the waveform if you want
Already answered to your highlighted comment 😉
I am trying to capture the wave in the oscilloscope. The sensor works fine. I am getting correct temperature reading in Arduino ide serial monitor. But when connected to oscilloscope, i am not able to debug which part is which. I even connected the diode like u said to differentiate the master signal from the slave. My professor wants me to find the 16 bits of the temperature that is stored in scratch pad and the digital value 16 bits has to match with the celcius value shown in the ide. Even after connecting diode and changing the resistor to 1.5k, i am not able to differentiate anything. The oscilloscope that I use is tektronix DPO 5204. How can i debug it. ( i am using in normal power supply mode only. Not parasitic mode)
The diode in line with the pull up resistor is just there so you can detect the parasitic power delivery by the master to the slaves. It doesn't help you detecting if the master or a slave is transmitting. It's the 100 Ohm resistors in line with the slaves' bus pins that help to differentiate between the master or the slaves transmitting ( ruclips.net/video/UIx8R1LV6HM/видео.html ). That's all coming to my mind right now. Hope it helps!
Hello, nice explanation. For detecting fire, what is the best sensor for arduino uno?
Thanks! And sorry, I haven't worked with fire detectors (neither smoke, nor heat, nor gasses like CO2) so far. So I can't really recommend any sensors.
Very good video. Super interesting. I have been working with these devices here in Argentina for a year. I am currently analyzing the intermediate frequency with artificial intelligence and fast fourier transform. The idea is to reduce false positives and use this module in alarms. I also did tests with the RCWL-0516, which is much inferior, and I noticed that there is a lot of influence between these modules. In fact, the emission is so low that it can be increased by adding more modules (just feeding them, without taking the data from the added modules). I don't know how this practice will influence the HB-100, but I'm going to try it. Thank you so much. Greetings from Buenos Aires.
Thanks for the praise! Doing a FFT on the output signal is definitely the way to go if you want to get the most out of these modules. Please let me know how using additional modules as transmitters works out for you. I think the challenge will be to make sense of the signal output of the single mixer, since the oscillators are not in sync (maybe close enough in frequency, but definitely out of phase). And greetings from Germany!
@@robertssmorgasbord What you say about ECWL-0516 is very interesting. From what I can understand, the device is basically a super-regenerative receiver. This puts the system at times in transmission and at times in reception. This change is given randomly over time. This randomness manifests itself as white noise, which is emitted in the form of RF with the frequency of the tank circuit between the printed circuit and the distributed capacities. The work changes are altered by a secondary antenna that increases the emitted power. It also affects the time it remains in the reception state. I also tried modulating the RF output with audio and it seems to work. More tests would have to be done. It's very interesting.
@@dbagnis Playing with microwave circuitry is fun for sure. I have to admit when it comes to the details, or more specifically, to make microwave circuitry exactly what you want it to do, I'm struggling. It's like black magic to me.
Hello, thank you very much for the good video. I use the Infineon TLV493D-A1B6_3DMagnetic sensor. What is your approach to off-axis correction ?
To be honest, I've switched to the A1335 (first video here: ruclips.net/video/b_1zqg0UZw0/видео.htmlsi=NmtvX_GhS9B3JnpM ). I'm using the internal correction table/mechanism of the A1335 nowadays ( ruclips.net/video/E37hL-k9jiY/видео.htmlsi=29HiJuzEU3BNqFS4 ).

@@robertssmorgasbord I have watched many, but lots of times parts of the process are left out. I think the PCB exposure setup could be improved. Some stray light always creeps in from the side. The light needs to be further away from the PCB.
@@jooch_exe You're right. When I came up with the idea for the exposure unit (basically reusing an old scanner) I limited the available distance between the UV sources (LEDs in this case) and the PCB.

What mill is that your using? I've ben looking for a handy little mill for a while now
It's a Proxxon BFW 40/E, BFB 2000, KT 150 Mill/Drill Combo. I picked it up used: ruclips.net/video/AKdBRVT9RWs/видео.htmlsi=o5tfuWR_liCQCfYE
The MK2788 chip on the mains voltage side appears to contain a GaN FET, so that part of the advertising seems to be correct... The complete ripoffs with a cheap 5V2A adapter inside are usually completely unbranded. It appears that EUR 10 to 15 can buy an actual GaN charger. Pity the output ports weren't tested on this one. I've got a cheap 65W GaN charger that I just tried, and it will simultaneously supply 20V or 9V to one port and 5V to the other, according to the PD or QC profiles negociated. Plugging in an extra consumer does blink the other ports, but that's merely an annoyance. There's a lot of crap out there, but I've also had store-brand chargers fail me big time. Thanks for the teardown, it goes to show that there are lots of things to test when evaluating chargers, and checking if the negociation actually is per-port wasn't on my list yet...
You're welcome! Testing USB chargers is not really my forte. I don't have any of the required equipment (USB dummy loads, USB protocol emulators etc.). My nephew got that thing at Christmas in a Amazon surprise/return box. Since it was completely unusable in Germany (wrong plug, wrong mains AC voltage), it was destined to end up in my slaughterhouse 😅
good day, I am still thinking of purchasing this Owon PSU since it is Linear. The P4603 is at around 200 € on Aliexpress. WOuld you still recommend it ? did you had still issues with the display? are there better option ? thank you!
Yes, I have still have sometimes trouble with the display. It seems to be a thermal thing that only occurs when it's cold in the room during the winter time. But that's just my unit. At that price point I still think you can't get a better linear PSU. However, if I had more money to spend back then I would have gone for the Rigol DP715 (about 350€).
@@robertssmorgasbord thank you! I will check that one up! I am also thinking of the Riden 6030W (60v 30A) controll unit about 100€ but then I need the transformer and rectifying bridge... Or use some Makita batteries in series 😂. I like the Riden since it has logging function through software and battery charging feature. Not sure about Owon and Rigol... Thank you!
@@catalinalb1722 You're welcome! But keep in mind, that the Riden is switch-mode PSU and not a linear PSU.
@@robertssmorgasbord I did ordered the Riden 6030W for 100€. Yes the controller is switched mode I guess that's the case with most of them. I will prepare an enclosure carrying 3 Makita Batteries, when done will release a video along with the 3D files for printing.
@@catalinalb1722 Looking forward to seeing that video 🙂
Thanks for sharing I was considering buying and repairing one. Will pass on it.
Yeah, it's too much hustle and too high a risk. Repairing/replacing the power supply is easy, but if something else is broken, things get tricky.
sorry did not send the company to the house did npt notice you were a super important person only that you say my brother name wrong bobby ridings cause i could not bite the apples bobbing on halloween at the apartments when i was little nfhl is totally fred ora all the way yall
I literally don't know what to reply to that 🤔 But I like the sky and the palm trees where you live 🙂
i suppose a tv show or a movie to find out about another man king was not possible thanks
Ah, you're welcome, I guess 🤔
Blazing material! Thank you for sharing it, found it very useful 😉
Thanks for the praise! And you're very welcome!
Puts you at Mörikestraße 63, 70178 Stuttgart, Germany
In the NMEA output, it shows your lat and long of your window. Might want to edit that bit.
Yeah, I probably should have 🙁 Anyway, thanks for pointing that out to me. But the damage is done now and so I won't reupload the video. In any case, that's just a window of my office space, so my privacy is hopefully still intact.
14:56 I was thinking the same, Danger! the parallels are -almost- on the way! At the end it was only -almost-
Yeah, live fast, hard and dangerous 🤣 But seriously, I would have preferred to get the second parallel out too, but it simply wouldn't budge.
Yes it is the detail. You unpacked the confusion I had with Termination and power for long time. Thank you very much
it's always the details 😅 And you're very welcome!
Thanks you. That was all I needed.
You're welcome 🙂
Hello, I could not trust most of the products, some seems like dots are available but actually not connected physically to the module. Can you suggest me a product with the decimal points, which I can drive with tm1637 or tm1650 ? Because I wrote my own library for raspberry pi and everything works fine except the decimal points. Some of the products work like a timing module even though they have decimal segments.
Sorry, but I can't recommend specific 7-segment displays, because beyond those kits I've never used and. In general I can recommend basically all 7-segment displays that are sold by reputable distributors, e.g. DigiKey. Anything you get from eBay, Amazon, AliExpress etc. is always hit or miss.
@@robertssmorgasbord Thanks..
