[@DevranUenal]

Normally I watch videos to get educated on technical stuff, but your videos are packed with a lot of informations AND are funny as hell. Thanks!

[@MickMake]

+Devran Uenal Thanks mate. Good to hear you're getting something out of my channel, both technical and humour!

[@jsking306]

Loved the Flash intro. I am not very technically inclined, but I learn something new from every video. Thanks.

[@MickMake]

+Joe King Great to hear! That's one of my goals; reaching people who wouldn't normally watch technical videos.

[@judgeguilty]

As a top hemisphere resident, I find your videos educational and useful. You're no Jeff Jefferies but your humor is good for a bottom (hemisphere) dweller.

[@MickMake]

+judgeguilty Haha. Thanks mate, no I don't claim to be a standup comedian, just a dad with lots of dad jokes.

[@ConnorWidtfeldt]

This is the greatest channel ever, I'm serious. The skits top things off.

[@MkmeOrg]

Great test!

[@MickMake]

Thanks mate.

[@haloded]

I love your videos mate! you've become my favorite now.

[@MickMake]

+Christian Colon-Fonseca Thanks mate. Glad you're enjoying them.

[@ami6packs]

top notch video. i gonna buy those LoRa modules. i like the way you compare the power consumption in different cases. 👍👏

[@MickMake]

+Amitesh Singh Thanks mate. They're a lot of fun. If you want to make it easier for yourself then get the boards with 2.54mm spacing or there's a PCB adaptor on tindie that you can get that'll convert the 2mm to 2.54mm spacing.

[@fouzaialaa7962]

lora is a new thing for me personally and im sure others dont know all that much about it so can you make a video to explain the lora module the protocols and how does it achieve that range and what should i use lora for ?? awesome video as always !!

[@MickMake]

+fouzai alaa Thanks. Yup I have a couple of videos planned with that in mind.

[@simonmerrett]

Great video. I'm not sure I'm as interested in the other RF technologies but I'd love to see more in-depth stuff on LoRa.

[@nullptr4042]

Nice sketch! keep up the good work

[@MickMake]

+John Doe Thanks mate.

[@RichardT2112]

John Doe Indeed, I'm not sure which I prefer the sketches or the maker stuff ... best maker site on KZbin!

[@MickMake]

Richard T Thanks mate. You've been around for a long time now. Back when I was in the double digit subs I think.

[@RichardT2112]

MickMake yup, I think I was 85th, but for comedic sake, I will say I was your 69th subscriber ... or 42 depending on how dirty your mind wants to be! :)

[@boogerking7411]

During sleep mode, can lora receive data? Or does it need to be at idle?

[@muhammadikramshabry2031]

mick, can you show me the port to measure the current?

[@seydunarojhilat4733]

how many mA spent when receive mode for a hour. and 1:45 what is the link of this page

[@Mastadex]

Cool! Can't wait for the nRF24 test; my next project uses them.

[@MickMake]

+Mastadex Alas I haven't had time to get these in before my holiday, but will be there on my return.

[@mostlymessingabout]

That is a bit extreme since regulation limits to just 1% duty cycle

[@ExarchNZ]

Can you do a comparison of the various module settings, in sensible increments, against battery consumption? I don't think it would be just a binary short/long range option.

[@MickMake]

+wraithbone Yup, unfortunately I didn't have much time this week to do more testing. In a followup video I'll be including tests such as different data rates and other variables, but the maximum and minimum "air time" tests gives you the best and worst case scenarios.

[@ExarchNZ]

MickMake cheers, keen to see that follow up.

[@JohnSmith-lv8xk]

Do those modules have a name / number ?

[@zl3dwh]

Where did you buy these LoRa module?

[@marianomontanez2095]

link to the calculator? @1:53

[@boogerking7411]

I wonder if you could make the node idle for only a few microseconds every second to minimize power consumption then sleep?

[@IMCDundee]

0:36 AC/DC concert training

[@MickMake]

Ha ha. A little Angus.

[@marinehm]

Nicely done. I like using new things. Well, new to me... What would be the various uses for this other than the standard answer of "streaming data"? How can I use this in a standard every day life use?

[@MickMake]

+Nick Sebring Long range Comms instead of using a mobile network. Chuck them out on a farm and running off solar and you can check your water troughs. Stick it into a high altitude balloon for telemetry. Put one in your car for logging your vehicle's movement without using GSM. Or use it as a vehicle tracker when it's stolen.

[@ShirishJadav162]

can I get the code you created?

[@fin.mehmetbsrr]

First of all i am new on this channel and this is the first video that i watched.I instantly subscribed and i dont know how i didnt realized your channel. Thank you very much for your work. Secondly i am also new in this technology and i have a few questions. Can i transmit video with this module or at least can i use this module to control rc? I am planning to use this module with arduino ,while transmitting video if its possible, is arduino enough or should i use it on rasperry? patiently waiting for your answers.

[@MickMake]

Thanks mate! Glad to have you aboard! LoRa really isn’t designed for huge amounts of data. Just really small packets every hour or once a day. You could theoretically transfer video over it, but you’d be annoying other people.

[@Aemilindore]

Could you please share with us the code you used to transmit LoRa messages? (not LoRaWAN). Thank you.

[@altamiradorable]

I really have to give you a big thanks for all your videos. They are funny and very educational. You might want to add a wombat or koala once in a while !! Then I would believe you being down under !

[@MickMake]

+altamiradorable Thanks mate. Maybe I should pay a visit to the zoo and record some footage there?!

[@RichardT2112]

Thanks Flash ... the jokes of that nickname and puberty will be avoided ;)

[@lubeckable]

Can i use a lora module in a drone?

[@MickMake]

Absolutely! Would work well there. Line of sight would go up to 20kms.

[@lubeckable]

MickMake thanks

[@JhonssonCOL85]

where do you find these lora modules?

[@MickMake]

+Jhonattan Fredy Moreno Bernal You can get them everywhere. Have a look at my Roundup videos where there's one almost every week.

[@ConnorSpeers]

In your calculate script results table, is the far right column supposed to be mA instead of mAh?

[@MickMake]

+Connor Speers Well the far right is mA consumed in one hour, so you could take it as mAh. The far left column is mA consumed in how long the test was.

[@ConnorSpeers]

A mA is a measurement equal to 1 mC (milli-coulomb) of charge being transferred over the duration of 1 second, or 1 mC / s. Thus, a little unit math would allow one to conclude that a mAh = mA * h = mC / s * 3600 s = 3600 mC of charge (the seconds unit in the numerator cancels the seconds unit in the denominator, leaving only mC in the numerator). So mAh is a measurement of charge, whereas mA is a measurement of the rate of charge transfer. Batteries are technically rated for a particular voltage, with their energy capacity measured in watt-hours (1 Wh = 1 V * 1 A * 1 h). A battery with an advertised charge capacity of 2000 mAh (or 2 A * 1 h) operating at a constant 3.7 V would have an energy capacity of 3.7 V * 2 A * 1 h = 7.4 Wh. Say you used such a battery to power a device that operates at 3.7 V and has an average current draw of 80 mA (giving it a power rating of 3.7 V * 0.080 A = 0.296 W), you can calculate approximately how long the battery will be able to power the device by dividing 7.4 Wh / 0.296 W = 25 hours. This algorithm can be simplified (and often is) by eliminating voltage from the calculations if voltage is assumed to be constant. So then the equation becomes 2000 mAh / 80 mA = a theoretical 25 hours of operation. Your results tables are consistent with of this if the far right column is a measurement of the average rate of charge transfer (mA) during LoRa operation, but not if it's a measurement of total charge consumed (mAh). But if I'm wrong, let me know! Just trying to make sure I understand everything correctly. Big fan btw, never heard of LoRa before this video, so thanks for introducing me to something that has huge implications for the world of IoT (and beyond)!

[@MickMake]

+Connor Speers Yes that's right. I meant to say average mA consumed and didn't mean total. The voltage and current logger tended to skip over some of the 1 mS samples so I had to adjust for that when generating my average.

[@gamerpaddy]

do lora modules have to bind together or can you set a bind key over spi ? i wonder what happen when thousand of people within 100km transmit like stuff.

[@andresc4]

Hey MirkMake can you specify the Tx packages sent on your tests? I would like to estimate how long a battery will last acording to the amount of packages sent per day

[@MickMake]

Hi Andres, I sent a range of packet sizes from 1 byte to 1Kb - cycling through packet sizes in 1 byte increments. Sending a couple of packets a day, you should be able to last for at least several months on a coin cell and a small MCU.

[@muhammadikramshabry2031]

what is the device you used to record the current ?

[@MickMake]

This was the Log4USB. Made by an Ozzie fellow. Does a pretty decent job of it.

[@muhammadikramshabry2031]

MickMake is it easy to use? Currently i'm doing research on current consumption of lora

[@tsfcancerman]

what would you need to buy to make your own pirate radio you can broadcast music over/on with as small form factor as possible but that can send over greater distances?

[@MickMake]

+tsfcancerman Just two LoRa modules. You won't be able to pick up the LoRa transmission on a normal radio, but you could certainly use it to transfer whatever you want between two distant points.

[@MickMake]

+tsfcancerman But to answer your question... getting an SDR would be the best, along with a decent amplifier. You'd need a lot of money still and depending on your country they have very good methods for tracking down pirate radio stations. Most of them are situated off-shore to get around any legislation. Note: If you do this, then it's by your own choice. I don't support the setup of pirate radio in any way.

[@eyesofnova]

What band does LoRa transmit on?

[@ellisgl]

www.thethingsnetwork.org/wiki/LoRaWAN/Home

[@MickMake]

+EyesofNova There's essentially two different models; 433MHz and 838/900MHz, although you can change the frequency at runtime.

[@FikiFirmansyah]

Cool edit 😎

[@boogerking7411]

Have you tried buying lora ICs from aliexpress? I see $1.6 each for an sx1272

[@muhammadikramshabry2031]

hi mick. where can i get the codings? and how did you connect the lora with the data logger?

[@izzieb]

Do you usually utilise all the products you purchase? A lot of things I see on your channel interest me enough to want to purchase, but I know full well I'll just mess with it for a while and never touch it again. It'd be interesting to see more of your projects, like the workout tracker with IMUs you were working on a while back.

[@MickMake]

+Izzie Hi Izzie, yup I try to make projects that are actually useful. There'll be a lot more projects coming up soon. I have some big projects with LoRa, Sonoff, Orange Pis, and maybe a roof top antenna. ;-)

[@ami6packs]

MickMake nice. looking forward to it.

[@izzieb]

MickMake Nice. I wonder if this could be powered, or at least the battery supplemented, with a solar panel.

[@MickMake]

Izzie Hmm. Now that's an idea!

[@izzieb]

MickMake Indeed. I suppose the microcontroller/SBC would be the hardest thing to power using solar power.

[@jereelh3199]

What if we only send signal every 10 seconds? Is the battery last longer?

[@nxxxxzn]

are there any decent platform agnostic sx1278 drivers written in C?

[@ammccoy4131]

Can i made rc transmitter with this module ?

[@MickMake]

Quite a few people have done this. Works well, but latency can be an issue. So you need to reduce the "air-time" as much as possible.

[@dj-evara9499]

Does LoRa has a good enough latency for telemetry ?

[@MickMake]

It depends on what sort of telemetry. You can have telemetry between the earth and the moon, which would have high latency. You can configure LoRa to spend a lot of time "on air" which would increase latency, but increase distance. So the range you want is a big factor here.

[@dj-evara9499]

MickMake my purpose is telemetry for drone, similar to 3DR telemetry. currently i'm developing a DIY flight controller using STM32F446RE. oh i got it, So sx127x should works for drone telemetry. i only need to send some string about 2Hz

[@MickMake]

DJ-EVARA yup, that'll work well.

[@boogerking7411]

1.7mA consumption idle? So it will only last 4.9days at idle with a 200mah cr2032 battery? I thought it consumes just a few uA?

[@MickMake]

During idle... yes, but transmitting/receiving it’ll draw a lot more.

[@boogerking7411]

I wonder if you could make the node idle for only a few microseconds every second to minimize power consumption then sleep?

[@pacgrafica4]

Help I need a rf wireless controller (transmitter and receiver) for a distance of 2 to 5km. To function as follows: On the transmitter is to connect a "PIR" motion detector In the recptor a led. The operation should look like this: After the "PIR" detects movement, it sends a signal to the receiver, which in turn lights a led. Thanks

[@pratikbin]

which size of headers you have solder with LoRA? (like .1" or 2.45mm etc)

[@MickMake]

These are smaller pitch headers. 1.27mm

[@sandrorrh6255]

Hi , if we put a capacitor between 3,3v and ground , something like a 220 uF , would that take care of the current gap ? i mean , would it increase the current to the number we need ?

[@wimwiddershins]

It looks like you had too much fun filming the Flash sequences. heh. :)

[@MickMake]

+Wim Widdershins Yup it's always the fun bit. Well the whole thing is the fun bit.

[@anucharuangsiriwattanakul7461]

How to wiring LoRa (Ra-02) module with esp8266 (esp12f)?

[@j49totocsp62]

Good job. Hello Mr. Do you help me about transfer data GPS with LoRa. Thank you.

[@altamiradorable]

I wonder if LORA has sufficient bandwidth to be used to be used as a means of transmitting RC signal to a drone in lieu of WI-FI (**pronounced why-fye here, not WEE-FEE) or the normal RC 72mhz band.

[@MickMake]

+altamiradorable Possibly. I would think that LoRa and WiFi would be too high a latency for classic RC, but the long range advantage of LoRa is appealing. You could use it for basic telemetry between a ground station and near-space balloon.

[@prototype3a]

I was wondering the same thing but I'm guessing it is too low bandwidth for something like Mavlink. However, combined with something like a teensy, you might be able to use it as a failsafe last ditch long range "RTL" request system.

[@rich1051414]

Would even a 20ms latency really matter much?

[@akarshagarwal4516]

hey Mick! I want to explore more sbcs, and as I'm a student I am low on budget. Can you suggest me some cheap sbcs available on aliexpress or ebay like the orange pi zero. I've already used raspberry pi. thanks

[@MickMake]

+Akarsh Agarwal The Orange Pi Zero and RPi Zero are probably your best bet. I haven't had a chance to look at the NanoPi Neo yet so not sure what it's like. Apart from that there's the embedded side; Arduinos, Teensy, etc.

[@akarshagarwal4516]

MickMake thanks for the reply Mick. but the raspberry pi zero comes costlier than the pi 3. lol

[@MickMake]

Akarsh Agarwal Ah yes, the scalpers are charging a lot for them.

[@Minecraftfreak3535]

You could try the RPi Zero W. Its 5$ more than a normal Zero, but you can get it directly from thepihut.com

[@akarshagarwal4516]

rupr thepihut also charge a good amount of shipping here to india.

[@wotid]

Consumption during the test run in mA? Nooo! mAh, my OCD is killing me even though I knew what you meant. ;)

[@josecampino7476]

Hello! Great video as usual, and rightly pointing the patience of our best parts dealing with our damn serious hobbys (my wife often call me a "51 year baby"). If you allow me a question, how do you wire RA-02 to Arduino? I only know that level shifting must be used. Any pins to pull up or down or caps? Greetings from Portugal!

[@dj-evara9499]

Hi, actually i have two sx1278, but i have not yet found an example of library of sx127x thru SPI. would you like to send me your sx127x arduino code and library ? thank you very much Devara

[@MickMake]

Hi, there's a number of libraries in the Arduino IDE. I'll post my code up to my GitHub page soon.

[@dj-evara9499]

MickMake thank you so much for your reply. I glad to hear that. actually i have found a library, but there is no example to use it. My sx127x is working at 470MHz not 433MHz

[@TangoMikePapa]

Can I have your GitHub Library/code please?

[@ufohunter3688]

It would be pretty pricey to setup a gateway if there are none around. www.thethingsnetwork.org/map As you can see, not many gateways are public in Canada. Also, can one of these small modules be used as a repeater, or do I need another gateway? If former, I am thinking of putting one up on the tree at the top of the mountain that blocks my line of sight to my destination (Cabin in the woods)? Use solar charging and batteries and hide it from people.

[@MickMake]

+UFOhunter Yup, why not! You would only need one of them if it's low data rates, but two if you wanted to push through the 500k bandwidth.

[@ufohunter3688]

But, Would I need a gateway, or just 2 or in my case, 3 modules will do? I would only need a gateway if I need connection to the internet on the other end? Right?

[@MickMake]

UFOhunter The best way would be to setup a LoRaWAN network, but you could do it with a straight peer to peer with several modules.

[@ufohunter3688]

That's awesome. Will order 2 more. Thx

[@Eih3Prog]

Hey ;) Can u share the arduino code to use this modules please

[@MickMake]

Sure!

[@Eih3Prog]

I just found Arduino samples code -> bit.ly/2qsSMdQ

[@MickMake]

Michel Esc Ah, yup was just about to post. There's lots of examples in the Arduino IDE. My code didn't really add much to it.

[@mohammedsaeed4599]

can you send the connection lora with arduino? thank you

[@faidularcs]

Really do you tested 500kilo!!!!

[@1st_ProCactus]

500Kms ? I assume that is line of sight. and there is no where on Earth that can be possible. If it could be done, it would beat the WiFi world record done with standard WiFi hardware, minus the massive dish antenna. Btw, do you call your Wife Wiffy? :D

[@MickMake]

+ProCactus That's right. It is *theoretical* after all. In reality you'd have to put the antenna up much higher to account for the curvature of the earth. WiFi? No, but I get called that before I've had a shower. ;-)

[@MickMake]

+ProCactus And yes, line of site would be a must!

[@thefatmoop]

If you're going to power it with batteries, you need to utilize and rely on the radio's ability to sleep for 1uA then sleep your micro and use a low Iq regulator. reibot.org sells dev boards designed for this

[@DanielRowe]

Can always tell a UNIX admin by the Perl 😀
