Fantastic. Love the clarity of your explanations and the level of detail that you include. It has given me lots of ideas to experiment with and your Sketch is a wonderful starting point. You make life with the ESP8266 much easier that it would otherwise be.

Brilliant video +Andreas Spiess, thanks.

I kept pausing to go and buy things LOL For example, those HT7333's have replaced my LM1117's now after this great video ! Very enjoyable and informative Andreas, thanks.

Thanks for posting such detailed work in this series. Very appreciated!

Thank you for the time you take to make these videos, and for sharing your knowledge!

Thanks Andreas, I've often wondered how to calculate loads vs capacity. Using ma/sec and cycles makes sense.

17 people have pressed the dislike button,, Seriously?! the guy is giving you free knowledge and you give back a dislike!

Excellent video, Andreas. Great info on the regulators! :)

I ran my ESP8266 from a 400mah Li-Ion battery for 20 days, measuring battery voltage at 10 minute intervals. Thanks again for your awesome and inspiring videos!

episode numbers: +1, english much improved: +1, calculations explained: +1 ... you're awesome, thanks for these nice and informative videos!!

Thank You for Valuable Videos and Your Time. I appreciate all!

Great coverage, Andreas. Keep them coming!

Thank You again Andreas for this well presented and elaborate project. I learned a lot in this short time, I was not aware of the HT73xx , great thing to use in my future projects. Thank You again and stay safe. Best Regards, Didier (From Belgium ... The country of the best chocolates in the world ;) )

Really appreciate your great work on these videos. Tremendously instructive!

Hi Andreas, Hope you are keeping well.. I am not a technical person your explanations in this video is very easy to understand. I watched on ESP 8266 more than 100 video really its very helpful in my project.

It was a great work, Mr. Andreas. Thanks for sharing and very helpful information. Respects...

I have not seen anyone explain better than you Thank you♥

Outstanding, complete and clear work. Second time I stumble upon one of your videos, I'm definitely a subscriber now :)

I'm from the other side of the Alps, I enjoyed your video, well done. And obviously I subscribed.

You make excellent videos! Thank you for your work and educating others (like me)!

I have to say, I love it. I already learned more than I expected today!

Andereas great video(s). I really like the way you approach the subjects. Really great work(s) and appreciate it!! Thank you!

Really enjoyed this video and found it very informative, its fantastic to be able to learn like this. Thank you Mr Spiess

Wow! Awesome. I live your solution for current spike. Thanks.

Great video! Thanks for sharing!

Thanks Andreas for another great video. I've learned a few things today.

Video is a little old, but, THANK YOU VERY MUCH for all the time you put in to give so much knowledge back to the WORLD. Always enjoy you r videos lessons.

Excelent video! Congratulations and thank's for sharing with us!

Always good!! Very informative and detailed, I didn't know much though, sorry. Thank you. I am learning new things watching your hard works.

Thank you Adreas, very usefull information.

Sure is an interesting topic to give the best attention possible. For sure my dear Switzerland accent guy, that was a delightful explanation of battery consumption on ESP-8266 module. Thanks a lot for sharing soo good knowledge..! 😃😃

Very good explanation with all hardware details!

Excellent video. Exactly what I'm interested in when it comes to smarthome nodes based on the eps8266. I would send the data to my in-house openHAB server running on Raspi2, but that's the same from the viewpoint of the esp8266. My witty boards are in the mail and I can't wait to experiment with them.

Thanks for the explanations. This regulator will help me a lot.

Fantastic work!

Hi, i watched almost all your videos yesterday. They are great, full of precious information! Thank you for doing them :) I would like to ask a more general question. What do you think is the most efficient way (less heat - and not too expensive components) to step down 12V to 5V and 3.3V for Arduinos and ESP8266 to be used in the same project? Thank you!

Very informative and very well presented!

Excellent video, interesting educational and practical - I've enjoined watching it.

Another great video . Congratulations on teaching.

Wow! Thanks for your time creating this great videos :)

These videos are great! Many thanks!!

Well explained sir ! Thanks for sharing.

Really impressive. Thanks for this Video. Very interesting.

Excellent video thank very much Andreas!!!

Brilliant video! thanks for this!!

Talk about "Power Napping"! ~excellent presentation~

Thanks for your post. Most interesting.

Good job sir!

Thank you for the information.

Good work,I am glade to see the wonderful video,thank you! This video solve my lots question

Sehr Interesantes Video! Sie haben die Spannungsregler und Kondensatoren (im video #47) wahl methode sehr gut erklären. Vielen dank für teilen ihre Ergebnis.

Hi Andreas! Very good video, again. Just one tiny remark: If you have no connection from GPIO16 to reset pin, the ESP does not stay in deep sleep. It (kind of) wakes up in a weird state and does not continue to run the code, but consumes about 15mA. So that's even worse than staying in deep sleep. ;-)

For another video, it would be interesting to hear about the rtc memory functions you are calling to keep state between sleeps. This issue of persistence has been on my list for storing known SSID/Password entries entered via AP most. A video on this topic would be really helpful.

almost a year late... but great video, thanks so much i learned a bit, time to start researching everything deeper

Please put the next episode on the FedEx truck, I can't wait to see more! The suspense is killing me. I took a cursory look at the code but can't figure it out. I have an esp8266 adafruit feather with a 3.7v lion 500mah battery and was getting just 4 1/2 days updating "adafruit io" once every hour. The esp would only go to sleep for one hour max. Great video, I don't see where you find the time for all this stuff.

Another great video, thanks! :)

great info as ever . very clear and easy to fallow .

Did a similar thing with a lifepo4 cell and small (4cm*6cm) solar panel. The idle power usage while the esp sleeps is so low that I had to purposely keep the thing awake to stop the cell overcharging. Surprised it actually matches its datasheet power usage after you disconnect any external circuitry.

Andreas, I looked up the specs on the HT7333 and it shows the quiescent at ~4mA not 4uA. Also a bit more digging shows the TI TPS78333 using an extraordinarily low 0.5uA, with a dropout voltage of 0.15V, it looks like it would be the perfect regulator for a sensor application.

im glad that youtube provides the option to step up the playback speed ... :D

Thanks you very much for knowledge

Thank you for the great videos, they seriously are very inspiring! With respect to battery runtime I am still trying to figure out which is the best minimal setup for a bare ESP12F module (using FTDI for programming). I understand that you need the following pins connected: CH_PD/EN => Pullup; GPIO0 => Pullup (for running; GND for programming); GPIO15 => Pulldown. And, for stability reasons: GPIO02 => Pullup; RST => Pullup; Electrolytic capacitor 1000uF between VCC and GND (as pointed out in one of your videos). What are the best values for the external resistors (sometimes I read 10k and sometimes “the smaller the better”) if I am looking for minimal energy consumption and/or stability? Some pins have internal pullup/-down resistors would they be a better choice than external ones? And does the maximum voltage level of a capacitor does have any influence on energy consumption? I know, a lot of questions, but maybe you can help shed some light?

Thank you this was what i needed:)

Very well explained

Thank you very much for this awesome and very helpful video! I'm going to give the HT7333 a try now! I hope the module is not too tiny so I'll be able to solder wires to the pins. Do you use a special soldering iron for SMD parts? Greetings from Germany, btw! I don't mind the Swiss accent at all. I like the fact that you speak slowly in the video, so it's easy for me to follow. :-)

Hi Andreas, I have managed to descrease esp 12F's Power consumption to 159uA by removing the LDO of Wemos d1 mini I Power it with my custom deep sleep wake shield. The shield is using 100nf in parallel with 100uF in paralel capacitors to HT7333 then HT7333 3.3v output is connected to 100nF polyester film capacitor for filtering purposes then I added 1000uA 3000 hour lifetime %5 capacitor to reduce peaks as you mentioned in the video. Then this Power circuit Powers my deep sleep wake part of the circuit and that circuit itself with Power components just draw 1uA😀 I also watched your PIR sensor videos and I have choosen HC-SR-501 and modified it by removing Diode cause it was lowering the voltage and removed LDO of it then I bridged VIN and VOut of LDO pins now it draws 36,38 uA when it is idle. When my sensor detects movement the wake circuit wakes esp12F from deep sleep and keeps it open until task is done then it goes to deep sleep again. With modified HC-SR-501 PIR sensor my sensors total current draw is 210uA in deep sleep with clone wemos d1 mini😀 with my calculations it will Last for 346 days with 2000mAh Lithium-Ion battery with 3.8 volts with single charge. Thanks for tips for lowering Power. I am also full time 12 years of experience C, C++ and C# programmer so lowering run times was easy. You can lower your connection time even more. My sensors connects the wifi gateway in 500,600ms if you specify mac address😉 I might remove the blue LED as you suggested for lowering consumption even more! Thanks! Keep the content coming we love it😀

great video Andreas

lol i read ubidiots.com instead of ubidots.com when clicking. great content as always. i'll have those HT7333's in my mind to enhance some projects. thanks!

Great info dude i m a fan now.... Small detail for Noobs is best. i like IOT but don't have time to read but your video teaches good.

Hello guy with the Swiss accent. :) What a wonderful channel you have. I am so glad I found it. You explore really interesting topics and explain things very well; easy to understand. I am curious if you are an engineer by training or just picked things up on your own? Thank you!

Great video, just great .

Those 6.3V 1000uF SMD Tantalum Capacitor had a leakage current of around 60uA too.

Great video!

Hello from the Netherlands Andreas. Great video once again. You always come back with all sorts of nice nuggets. The tip about the ADC_MODE(ADC_VCC) and ESP.getVcc() methods was very helpful. How did you calculate the VCC_ADJ at 1.096? I also noticed that BATT_WARNING_VOLTAGE was set to 2.4V. I thought the working voltage levels for the ESP was 3.0 to 3.6v? Or can it go as low as 2.4v? Great stuff again and keep up the great videos. Mark

Very good. Thanks!

Hi, Andreas! Congratulations for the great video! Can I use 1000uf 6.3v electrolytic capacitors instead of tantalum capacitors? Thank you!

I've had good success with the 2CR1/3n 6V battery for powering small microcontroller current-intensive devices, it will provide 60mA steady and 80mA pulse, 160mAh for Li-ion type.

I was looking for something like the ST1L08 or the LDFM voltage regulator, but it's quite hard to find. I really liked the option to shut it down digitally...

Hi Andreas, you use also the quite big white board to solder the ESP on it. Do have found in the meantime a smaller version that has the size (width) of the wemos shields? I see still only on aliexpress the white boards from the video. I really like the already included pullup resistors and the place to solder the voltage regulator. All great. Just a little big too big for my outdoor housings.

nice video !!!

Thank you very much

Just found your video's and am really enjoying them. With 2 alkaline battery's what do you consider the minimum voltage before replacing them. You wouldn't even start out with 3.3 vdc and can't imagine that would work.

Thank you for the good an informative video, Anderas! Is the 10.000 uF tantalum capacitors leakage current relevant? Where did you buy yours?

Interesting video, thanks for sharing! Waiting impatiently for my NodeMcu Lua ESP8266 from ebay :) This will help my future project, want to run on battery for a long time.

Hi Andreas, Hope you are keeping well.. Thank you for another great video, you just keep getting better and better. I m working with a small solar cell, 2 x 10F super capacitors and a TPS61200, just got the super capacitors today, so testing them now I have been running an ESP from a 4.2v - 3.7v Li ion 18650 through a MP1405 (TP4056 .with battery protection and load cut off) in deepSleep with 60sec cycle. Transmits DHT temp/hum and ADC_VCC to Thingspeak Surprisingly, it tolerates the voltage and has been running for 2 weeks without a glitch. The battery is also fully charged. I know this is naughty, but just wanted to see if it would work. Could it be the deepSleep and short awake time be a contributing factor to this? My ESP 4MB chips arrived today along with my hot air rework gun. Many thanks for making all this possible Andreas, your work and methodology make you a great teacher. Massive thumbs up, keep them coming

Great video... as usual ! I'm thinking of running an ESP from a battery also, so you are a great inspiration. However, I know almost nothing in passive components. I understand there is a need of a capacitor for removing peaks of current, but I can't find those huge 10 000 uF capacitors. Is it possible to put an électrolytic one instead ? In the video you said there are huge. Is a 300 uF enough ?

I have a LM1117 that i use to provide 3.3v for breadboard projects. It uses 10mA all the time, so not good for battery use. The HT7333 sounds promising for my solar powered esp12.

hi there, congrats, great video. What RTC ic you are thinking to use when operating with larger periods? How about make the RTC "wake" the module? Could decrease the 8min operation time? regards,

This is a great video , thank you for posting. The quiescent current appears to be very large. It would be great if we could power this device for a period of 1 year. any ideas ?

Much appreciate your great work. Unfortunately Phant of sparkfun is no longer in operation. I will try with adafruit service and Supercap, solar panel combination for power. Please make some video on energy harvesting for sensors. Danke ;)

great vid. thanks.

Thank you so much for your sharing. Your channel help me a lot while working with ESP. Just one question, I know that the regulator of ESP is optional for your White Adapter, and in case of you want to use regulator you need to desolder the short-circuit 0 ohm resistor in the middle, if not your input-voltage connect directly to 3:3V. But you didn't do it there, so I don't know how your ESP can still working ?

Nice video ! Thank you! What about to use external RTC and completely turn off power from ESP8266 ? In this case you can drain 80mA just for sending data and about 5uA left time. This means that from Li-ion battery with 100mAh such combination would work at least 150 days with 1 hour period of sending data.

Thanks for the subtitle, if more videos of you had subtitles the success of this channel that already is very good would be even more. How would you like more subtitles in Portugues

Many thanks for the info about HT7333. Will use it in weather station outdoor with one 18650 LiPo battery. Greetings from Russian viewers)

I really love the swiss accent, it is the same when then speak french.

Finally one last video topic suggestion on using the ESP8266, MQTT and security. While I have read on some forums that it is possible to run MQTT securely with TLS1.2 on the ESP using a native C Xtensa development toolchain, it would be really helpful to understand if you have ever explored doing this in an Arduino IDE environment for the ESP8266. Everything I have ever seen with the Arduino IDE is only using unsecured communications. Seems like something seriously holding back the IoT market. A two minute session with Wireshark exposes all hobbiest username/passwords with all of the newest MQTT services.

You have solved the conundrum of the LDO supply by using the ht7333 - ebay ordered already :D

Thx rus subtitles. Ставлю лайк за русские субтитры, к сожалению в других Ваших видео они не работают. С удовольствием просмотрел бы и другие видео.

your videos are great !!! don't lose that swiss accent by the way
