zynoda me too! I am really interested in the one with the 18650 compartment!
@keilo88 6 років тому
Im curious if it has a feature (gpio pin kick) when the main power is cut off (i.e. when its running on battery). Cant seem to find any info about this unit. @Andreas Spiess do you think the board might have that kind of capability?
@vladoprisa3609 6 років тому
Hello everyone. It would be great to see the ESP-32 with embedded display performing a multi-threading task like: receiving the display content via WIFI on the first thread and the second thread managing the display. I have tried to address a similar task using ESP-8266 but sometimes the Wifi lagging out stalls the display routine. Also Andreas, great channel, great stuff, great gadgets. Congratulations!
@ipodmaurits 6 років тому
I want to buy some too, but not sure about the quality, usefulness and breadboard friendly about some of those boards. they seem interesting though
@erygion 4 роки тому
It's an old one but I haven't seen it and you know what they say... I love the mail videos(it's true it's bad for the wallet), your sense of humor and a lot of these items. I also managed to "persevere" to the end. Loved the new green energy video as well. I'm hooked :) thank you for your time Mr. Spiess.

RTFM - My father used to say that all the time. In addition to the (spelling for the reports to the commander ) the P-L-U-G was found to be on the floor or the O-N / O-F-F switch was found in the O-F- F position. Numerous electrical systems for the troops were repaired when these condiitons were found. Thanks for the memories. :)

@ErnestGWilsonII 6 років тому
Do you have a Patreon account or private Slack channel for your viewers to join? I would gladly subscribe and contribute each month to help pay some costs and/or donate / mail in new and fun items for your mailbag! Years ago I was badly injured and can no longer solder very well, as such, I enjoy watching you build and test things in your electronics lab much the same way I used to do! Each of your videos is like a fun television show for me! Great channel and great content! Don't be afraid to show us when things don't go exactly as planned, such is the spice of life! Thanks again for making great videos and sharing your journey with all of us! 73s W3TCP

@AndreasSpiess 6 років тому
Switzerland is a very international place. Maybe this is the reason for this procedures...
@garrypkeogh 6 років тому
I see what is coming... one more month waiting for all my ESP32 parts in the post. After much luck with ESP8266 I have a couple of applications which need more GPIO and a few D1 Mini which block the single ADC with battery status monitor. I guess the SDK is evolving if the ESP32 is on your agenda again. This should be interesting! Thanks for your continued work, Garry
@AndreasSpiess 6 років тому
I decided to give the Arduino IDE for ESP32 a second chance (together with the board test). We will see... Now, the boards are cheap, and the time could be here to replace the 8266...

@EwaldBurger 6 років тому
Thanks for another mail bag! Soms interesting items. By the way, the extra headerd pins that come with the clone arduiinos are to be soldered next to te standard female headers. This provides a nice extra way to connect wires. I consider this a great plus compared to the original arduinos.
@AndreasSpiess 6 років тому
You are right! Did not see the holes. I remember, I had one which came with them already soldered. Really handy.

@AndreasSpiess 6 років тому
:-)
@dubbaluga 6 років тому
Thank you very much for your high-quality and informative videos! I am looking forward to the ESP32 board reviews too. When doing the review, maybe you could also look at how usbserial converters are integrated into the circuits. From what I have seen, they are hard-wired on most boards (e. g. ESP8266 Wemos boards). That makes them pretty unusable for driving them using solar power, because the converter needs 15-20mA at all times.
@AndreasSpiess 6 років тому
I never use boards if I want low poser consumption. I only use modules without anything I do not need.
@rainerpoisel2400 6 років тому
Andreas Spiess yes, I know. IMHO, there is no other way to achieve the goal of low power consumption at the moment. However, I was hoping, that board suppliers get on that track too. I do like the Wemos boards a lot due to their form factor. And I think it would not take much to design circuits to support low power scenarios as well. Maybe with the new ESP32 boards things have changed ...
@ReflectingMe2024 6 років тому
Yep Andreas, I watched until the end! Love the RTFM comment! Looking forward to the ESP nn reviews!
@AndreasSpiess 6 років тому
Congratulations!
@peterleather6866 6 років тому
Looking forward to the ESP32 review video. The 18650 Wemos boards look interesting too. I wonder how well they will perform in deep sleep mode?
@AndreasSpiess 6 років тому
We will see, if they use a linear regulator for the ESP..
@AceL. 6 років тому
Peter Leather. They use the old chip revision. With the not-so-low current while on deep sleep.
@AndreasSpiess 6 років тому

@AndreasSpiess 6 років тому
+Peter EIER Thanks for your feedback!
@RonanCantwell 6 років тому
Your poor postman! Some interesting stuff in amongst that lot. The touch sensor led modules are a great idea. It would be interesting to see how sensitive they are and if they can sense through acrylic sheet or glass. As for the "Wemos" boards... It looks like they'll print that name on anything now to try and sell it. I'm just about to enjoy a nice cup of Wemos tea with some organic Wemos biscuits.
@AndreasSpiess 6 років тому
I put one behind a 2.5mm plexiglas and it worked.

@ricardojframos5836 6 років тому
Hi Andreas ! I Like very much your "teachings" and the way you pass clearly the information ! Thanks for all ! Great Job ! I have an WeMos D1 R32 and i uploaded your Sketch "ESP32_GPIODiscovery.ino". After tha,t i simply placed a jumper wire instead of a push button, connected one end to the board's GND and started do try diverse testings with the other end of the jumper wire..... Well, i found that GPIO 0(GPIO zero) is the first Pin from the sequence IO0,5V,RST,3V3,5V,GND,GND,VIN (at least at this board that is specified at the silkscreen) on a regular UNO there isn't any text, but i think it is the same pin assignment for all WeMos ESP32 UNO like boards, like the ESPDUINO32, WeMos TTGO ESP32 and the WeMos D1 R32 (mine) !!!! But not the UNO's !!!!. Now the spooky,funny,interesting part of "that" testings....... ....After i tried some ""RISKY"" connections like ittentionaly shorting 5V+GND and 3V3+GND......( KAPUFF !!!! Eureka ! ) I saw something weird.....and even found a method to reproduce it or else it doesn't work..... After turning OFF the board and turn it ON again, just Push the RESET BUTTON and after that shunt quickly 3V3+GND and you will have this following message on the Serial Monitor window: rst:0x8 (TG1WDT_SYS_RESET),boot:0x0 (DOWNLOAD_BOOT(UART0/UART1/SDIO_FEI_FEO_V2)) waiting for download .....Waiting for Download....... (SELF EXPLAINABLE, i think !!!) Well with this version, it seems that ESP8266 BOOT function still exists (but hidden without the RST Button), i wonder what's the purpose of it ?... maybe it's not or something else.... ....tell me what you think what you think that might be.... See you !
@AndreasSpiess 6 років тому
If you connect GPIO0 to the ground while resetting the board it goes into upload mode and waits for a new sketch

You are right. In the meantime I got his Neopixels, but had no time to check them out...
@GnuReligion 6 років тому
Yes, lots of interesting stuff. I want some of those inexpensive AC/DC modules from Tenstar Robot. All sorts of good ESP modules. That writing tablet is bizarre. I hope you take it apart.

@AndreasSpiess 6 років тому
I first have a few others on my list...
@AltMarc 6 років тому
As you're interested with speech recognition on the pi, could I suggest to look at the microphone arrays "Respeak" form Seeedstudio, the cheap 2 mics hat and the more expensive but interesting far field 7 mics board ? And when you test the esp32 with lipo charger, could take a look of charging circuit, specially if their is a way to reduce the charging current?
@AndreasSpiess 6 років тому
I did not find a "cheap" micro, only the expensive platform. I think, for these things, I will stick with my Alexa for the moment. Why would you want to reduce the current?

Why? because of Li-coin cells and others, which don't like 500mA charging.( for using the ULP or the wake up inputs...) On the schematics of the sparkfun esp32 thing, there is a note about how to modify the charging current. Arn't they clones? BTW: coin cells with holder fit nicely in the with of the esp32 thing.
@AndreasSpiess 6 років тому
OK. Now I understand. I will have a look at it.

WeMos boards have become so popular that in addition to the clones you can find WeMos silk screened on clones of other companies/makers. It seems that is why WeMos changed their logo to WEMOS in squared font about a month ago
@AndreasSpiess 6 років тому
With the Chinese, the form of a logo does not seem to be a help in separating the good from the bad. They are very quick with copying everything.

Very interested to see what you think about the 18650 wemos boards... saw that on ali and almost picked up. These mailbags are great.... I made it to the end! :) Thanks!

Great video i like postbags. I am often interested in the efficiency of power supply devices(save the planet and all that...). Its a quite bit of a work to setup and measure that and make load/efficiency curves so a lot of youtubers never do that. And to be fair it sometimes can be found at the manufacturer. Perhapps an idea for a video sometime. I like power supplies that have efficiency >85% that also helps when needed mount them in small compartments that have poor heat dissipation capabilities.
@AndreasSpiess 6 років тому
+Nicklas Persson You are right. This is the purpose of my small power meter. I intend to connect it on the "primary" side and measure on the "secondary" with the electronic load

The GPIB (General Purpose Interface Bus) format is already a standard, unless it's been revoked and replaced. IEEE-488 is the number if I remember correctly. It was used for early Commodore stand-alone floppy disk drives before they were changed to use a serial connection. It's a 16-pin format with 8 pins for bidirectional data transfer and 8 pins for ground and signalling. All I remember now about the data transfer format is that it was a master-slave system where there is a single "master" which does all the signalling, and it begins a command by asserting the "ATN" (attention) control line.

Hi Andreas! Hello from Canada! Great video I must say! First I see you on UKposts and I am now subscribed :) Can't wait to see all the project you plan to make with all these boards from Banggood! How old is your little one that will play with these Arduino's?

+Sébastien Leprohon Welcome aboard! It not for my son, but for my neighbor. And he is around 20.

Oh, I dug out my ESP32 and played with her for a short time this morning, then It dawned on me, I had installed Mongoos OS on it, I ran it up and found her IP address, then opened it in Chrome, and brought up a nice webpage with Welcome to Mongoos on the top, with instructions on how to use it. I am not all that familiar with Mongoos but I think it is a C++ spinoff for such boards as this Gives me something to study next week when we take a quick week vacation up at Fort Abraham Lincoln Just south of Mandan North Dakota, where General Custer last slept in a bedroom, before his long trip to Montana and the Little Big Horn river, where he and his entire group were slaughtered as they tried to force the Sioux and Cheyenne back onto their reservations.
@AndreasSpiess 6 років тому
Sounds like a nice place where you live... I was travelling a few times in your beautiful country , but so far, was never in South- or North Dakota. As a Harley owner, I might change this once if I come to Sturgis ;-)
@JerryEricsson 6 років тому
It really is grand if you don't come in the Winter. Now that we have grown a bit old, we have been escaping the winters by heading to Arizona for that season, not sure how that is going to work this year, but we shall see I guess. Yes Harley Riders love Sturgis, we live 175 miles North of there however I get down there several times a year since that is where my Veterans Administration Hospital is. Long drive to see the Dr but the price is right (free!). The Black Hills of South Dakota are a true wonder, We enjoy driving through them several times per year as well. Here about three years ago, we drove out to Yellowstone National Park and spent a week taking in the Sights, they were indeed great to see, but a sort of disappointment after the Black Hills experience. More wildlife out in the Park, and the geysers are a wonder as are all the thermal ponds and such, on the way we did stop at the Custer Battlefield in Montana and saw where Custer met his match in the person of Setting Bull, Thunder Hawk, and Crazy Horse, all great leaders of their tribes and nations. The history that abounds this are is amazing when you set down to absorb it all. They say that Every Harley Rider must visit Sturgis at least once in their lifetime, come on over and enjoy the excitement and the wilds of South Dakota!

Hi Andreas, have you tried the HLK-PM01 power supply? What kind of curcuit protection, on the primary and secondary, should we use? Best regards
@AndreasSpiess 6 років тому
1. No, I did not use them 2. Normal fuses are always good on both sides.
@underwoodblog 6 років тому
Very interesting finds. I have to order some of this stuff soon. Check out the "FastLED" libary for the Neopixel/WS2812/SK....
@AndreasSpiess 6 років тому
Thanks for the tip with the "fastled" library
@spikekent 6 років тому
Very interesting as always. Will you be doing a video on how to build the self-balancing robot?
@AndreasSpiess 6 років тому
There are already online (ukposts.info/have/v-deo/q2WeYXqLpW6b2qs.html)
@spikekent 6 років тому
Fantastic, thanks Andreas.
@patrichausammann 6 років тому
Nice video! I bought myself such a brass "sponge", for cleaning the tips of the soldering iron too, they are not bad. I also bought an ammonia stone to clean those soldering tips. Have you ever used these stones? Greetings from Switzerland :-)
@AndreasSpiess 6 років тому
No, I only use these brass sponges. Where does this stone help?
@patrichausammann 6 років тому
It is a white, not very hard material in a little round box and after the advertisement, it should be mild to the solder tips (not too abrasiv). But I haven't tried it now, but thought that you maybe had used that item already.
@WacKEDmaN 6 років тому
did you try running the esp13 shield in standalone mode?..i have one and could never get it to talk to the arduino..aparently the TX/RX pins are reversed on the shield...but if you run it standalone you should get access to the esp8266 chip
@AndreasSpiess 6 років тому
I tried it Stand-alone, also got a new firmware and flashed it. But still, it does not work...
@WacKEDmaN 6 років тому
if you managed to flash it..then its working!... you need to ground GPIO pin 2 (or is it 13?!) to get it to boot into normal mode IIRC (its been a while..i eventually went to a standalone esp-12 and nodemcu)

Yeah, really looking forward to a ESP32 shootout. Especially the quiescent power draw in sleep mode. A lot of ESP8266 draws way too much power when in sleep mode due to USB to serial converters and ineffective DC converters.
@AndreasSpiess 6 років тому
I will not measure quiescent current on development boards, because I know the result: It is very (much too) high. I only will measure it for simple modules (as I did with the ESP8266).
@ReevansElectro 6 років тому
This was very useful and I would like to ask if you could include 'hot deals' for interesting devices that you come across with included links. Thank you!
@AndreasSpiess 6 років тому
So far, I only included things I purchased in my mailbags. And I consider all of them "hot deals" if you see, what you get for the money. Otherwise I probably would not buy them ;-)
