I’m the author of this voltmeter program for the M5Stack Core2. It’s an honor to see my work featured on this channel, even though this UI design is outdated and I’m not a fan of it anymore. But it’s really nice to see it in Dave’s workshop. I’m not sure what happened with the sensor; on my setup, the example displays the correct polarity.
hi Volos, i was mentioning - see below. its a problem within the Voltmeter.h file - maybe you was trying something out. #define VOLTMETER_MEASURING_DIR -1 …
At 7:00 in the video, the image on the letter that was included in the package to Dave shows the unit measuring +5V but displaying -5V. EDIT: Oops, I see Dave pointed that out later...
The problem with the meter is obvious. They sent one with the northern hemisphere firmware loaded. Download the southern hemisphere version and it'll be fixed.
Thumbs up to Victor. That edge connector is very clever. Maybe I can convince our manufacturing department that this is a good solution for programming in the production line.
@@EEVblog I bought a cheapo LCR tweezer jobby and its shit. They are handy though - so a shootout would be most welcome. I'm definitely in the market for buying a new one.
I appreciate the time and effort that you put into the Mailbag. It's only 54 minutes on UA-cam but I can see that a lot more effort has gone into it (i.e. the succinct clips flowing into each other to demonstrate an item).
That was my first thought as well. Without having seen other devices, chances are that in the letter the sales guy picked the very unit they send Dave. At least I hope for them that they don't have that issue with all of their units. ;)
32:30 - you can run HomeAssistant in a container, or in a VM - they just encourage you to run it bare metal because it's got the closest access to the various hardware you might attach to it to let it communicate with other devices - zwave/zigbee dongles, rs232 interfaces, that kind of thing. But if you know what you're doing, it won't know or care about the difference.
Yea, I set up HA OS on my Pi them moved it to a MU. But I just moved it to a TrueNAS vm and it was super easy to point the VM to the USB BT and Zigbee dongles I use. It was super easy to back it up, install the VM and restore the HA instance. I'm also running the TrueNAS instance on an Odroid lol.
I would rather just install it "bare metal" if its on my home computer. Containers or VM just adds complexity that is not needed in your home enviroment.
Thank you my friend. It is nice to see my work on this great chanell. I would have liked if they had used a more recent example, but it’s fine-this one is great too.
The LCR tweezers do tell you the polarity, if you look on the screen it shows an extra diode symbol between the legs/arms of the tweezers to show polarity.
I've used that voltage module before. The documentation and library M5Stack supplied at the time had a typo that caused readings to be inverted. I'm guessing whoever put this together was being quick and just didn't realize the documentation was wrong. The circuit and chip, when used with traditional Arduino or MicroPython works a treat and registers correctly

Yes LCR shootout. I believe Matias did a good practical review of FNIRSI's, on his 'Matthias random stuff' channel, as well as Defpom has compared both of them, if you're looking for ideas. I believe the UI and UX and finish are probably the most important to test for these things, as long as they're not completely failing their specs.
I've love an LCR tweezer shootout! Be sure to update all the firmware. That HOLD button can save the measurement to a file (data logging feature added to the Zoyi MD1). I wish the MD1 could do more than 0.6V. Then I could test LEDs in torches! I had fun visiting Zoyi earlier this year while visiting HQB for the first time in Shenzhen.
You'll notice that the colour image of the meter in the accompanying letter shows the meter being tested and it also shows inverted polarity there... it was the first thing I noticed when you showed the letter at 7:10
I bet if you look at the code for the M5Core2, the firmware they put on it probably has a mistake in the code that reads the wrong input as positive and negative. Likely just got the pins swapped in the code by accident. I use a few of the M5Stack Atom Lite S3's and a bunch of ADC's to measure a heap of sensors dotted around the place. They actually work really well, and the package is much better than most of the ESP32 dev boards available. Better yet, the various cases and devices are all built to fit into Lego Technic frames and machines you build. They were originally designed for kids at school to make robots or all sorts of other fun stuff out of lego and similar components.
Yup. The UIFlow library just has a typo. far as I know it's never been fixed (but I haven't used it in a few years.) the micropython and arduino libraries register it correctly.
That edge wedge is a thing of beauty. Coolest thing I've seen in a while. Hats of to the creator, nice brain action. I just put one of those mini pc in my milling machine for linuxcnc, a T8 firebird with the n100 chip, runs like a wee ripper. At 220 NZ kopeks with 16gb ram and 512gb ssd, a no brainer.
One little thing you might've missed is that the integrated C cable of the powerbank is input and output. Don't know how common that is, but I think that's a cool little feature.
Yes please on the LCR Meter shootout episode, I just have a UNI-T SMD tester, so no inductors for it, but works well and I'm happy with it. Afraid I'll blow through it's max 36V warning some day... : ))
The multi-NIC mini-PC boxes make excellent firewall/routers. Newest fanless ones have 4x2.5G ethernet ports. I've used one of the older BeeLink boxes as a mail cache here which is very handy.
The M5Stack is an easy IoT building block you can program using many tools and frameworks UIFlow, arduino studio, micropython ... It's basically an improved ESP32 DevKit with all the bells and whistles (display, RTC, LiPobattery, BMS, USBC,Dupont connectors) in an ergonomic form factor, replacing the usual breadboard+esp32+wires+...you would need to prototype some home wifi connected appliance. Much more powerful than the usual arduino thingy + shields (but more expensive as well). So it just seems that the little example program which was run by the M5Stack had inverted inputs for the Voltmeter module.
The continuity function on the LCR tweezers could be useful for troubleshooting. You could use it to test fuses, check if caps have shorted, check if inductors have failed open circuit, etc. it may be easier to do than using a normal multimeter and having to hold and position both probes.
I thought everyone knew about M5Stack, I use an M5Stack-C3 controller with PlatformIO/Arduino and made a watt meter with one of their Current and Watt meters which works with up to 240 Vac....
Damn! Get me one of those 11,000Ah battery packs, I'll keep it in my EV as a backup battery. In fact they looks quite small, I'll buy five. Could go a whole week without recharging then 🤣
Put the dongle in the slower USB port on the rear which will be more than fast enough for a mouse or keyboard and have the front ports for more often plug and play stuff.
Our Beelink EQ system has a Core i3-N305 in it. Apparently it was discontinued the same year it was introduced- at least that's what my brother says. It has a 12V input on the back for power. I need to order a spare fan for it.
im wondering if the swapped polarity on the voltmeter is due to two different people in their team noticing the same issue - the programmer : "let's invert the reading in software to make it correct!", the designer "let's swap the labels!". So at the end it's exactly the same :D
Note to case designers: "Mark the end with the Phoenix connector with + and -. in a large size font The + should have a red background and the - a black background." That's all the info they need, right?
The zoyi meter works quite well. User fault. Excellent at measuring in circuit and to measure caps it’s brilliant. Dude. It litterally show you the direction of the diode on the screen. And you must pick the correct volt it used to measure caps. Also the frequency is changeable.
I wonder if M5stack's Voltmeter was designed to have the information sticker on the front and name on the back _but then_ they realized they'd put the ISOLATED on the longer side and just went with it. (Or some executive made them switch sides it a the last second and they missed it, etc.)
Having used one, the issue is that their libraries have a typo. Both the micropython and arduino libraries for the adc register correctly, but using their UIFlow thing always returns an inverted value.
Probably been a feature for a while but I watch videos full screen and hadn't seen it till now.. When you said "Thumbs up or thumbs down" it highlighted the thumbs buttons on youtube. Crazy times.
I have a couple of the Beelinks. One I used as a media PC failed after a couple of years. So it it is hard to say if it is a bargain as far as longevity. On the surviving Beelink, I have vmware installed to run SDR software. So you could install vmware and run HA from that. I have found HA is a bit of a pain to work with and their updates always seem to break something on my setup. However that is the price you pay if you do not want to send all your personal data to Amazon or some other company that you can pretty much count on to abuse the data they collect on you.
I doubt it is the label that's the problem with the voltmeter, I bet that sensor came that way from M5. More likely his VM firmware is reading the sensor data backwards
I bought the m5stack cores3... Very impressive BUT you can't use the JTAG pins for the debugger interface. That means it's not possible to use the 'real' debugger in visual studio code 😢.
Sorry Dave could not watch that PC bit where you had the camera on the screen.... That focus hunting had me almost up chucking mate, just a suggestion there if you can't tie it into your atem just make sure the camera is locked on manual focus, I promise i tried but my eyes really started hurting, apologies mate, the rest though was steller as always.

Zoyi twezers indicates the polarity (anode and cathode) of a tested diode on its display.
42:30 you should be able to change the voltage that probe uses. It's voltage level is too low to hit the threshold voltage of some diodes.
It would be awesome to have an LCR Shootout!
The M5Stack reminded me of the "Seeed Studio Wio Terminal" which had some more connections and switches.

Dual boot Dave or install it on a virtual machine if you want to use that windoze install, you can run HA inside a virtual machine.
10w is nuts for this mini pc on idle, should be 5-7w. Well I'm sure that pre-installed bloatware (w11) adds a fair margin.
