@@Hajdew I tried it. Didn't work.

Good idea for an improvement

Or a series of gps location

@@greatscottlab Airtag and co would make everything obsolete

I was looking for this comment! Glad Scott saw this

@@iwantitpaintedblack Airtag has no GPS, this little device isn't really that convenient anyway, but at least it's probably cheaper. Keep in mind though that any message sent via this device cannot be misunderstood: the receiver will know exactly what is going on. Most other systems require that you manually decide to check out the tracking information rather than providing an "alarm" button

I used the interrupt pin from the Gyro to wake the Arduino, that checks if there is costant movement, then in turn controls the PowerEN pin on the GSM to switch it on and send a message, then everything goes back to sleep.

He could do that with the GPS (more ineffectively but for free)

he did just this but with a text message a while ago

oh THAT caused me all the trouble on my weatherstation! thanks

Ive just finished datalogger that uses sim800l, it connects to thingspeak and uploads data few times a day. Ive had to use 38400 baudrate to make it work and small buck converter to supply it with 4V. No problem whatsoever other than antenna supplied is a bit weak. Superb and cheap little module

at standby it consumes around 25mA at 4V, max I could measure with my DMM is around 100mA while posting data, I guess those few Amps bursts are so short I couldn't see them without a scope

@@clixium You are right. The burst while sending are way to short for an DMM. I found the problem only by probing the supply with an oscilloscope.

@@anselml2928 I noticed the same thing. Big current spikes at first but then it happily ticks along at fairly low power. If it doesn't get the power on connection it will fail and it's VERY picky about this. Great little module though.

You are welcome ;-)

don't know if this is still a thing, but on an older samsung phone I saw you could just press a button to receive a fake call and it was a factory built-in feature

@@richardbottom9843 Yep, had the same thing on my old Symbian Nokia too

@@richardbottom9843 I have a Fossil hybrid smartwatch that has a "find my phone" button that makes it ring, very useful lol, I imagine a lot of smart watches will have something similar

@@notaname8140 Yes cheap smart bands of mi etc also find my phone feature which rings my phone

Thank you! Cheers!

Love conversations about triangles, especially ones built upon 💰

> (you don’t want those you are trying to escape from seeing it) I mean, considering how it currently looks more like a bomb trigger than a sophisticated cellphone you might not even need to activate it

Do you have a huge box in your pants, or are you just glad to see me?

Thanks mate :-) There are debates about the music. But I think the animation and music turned out great :-)

@@greatscottlab no man please change the music

How is this comment 3 days old ?

@@greatscottlab I actually think the music is fine - but the animation is *brilliant*!

@@lieblingsfarbe4453 magic

Thanks, will do!

Back in 1995 the monthly cost of the cell service for it would have been pretty high.

@@gblargg while that is true, the products were rejected because the car recovery companies of the era felt the GPS functionality was overkill. Their words “nobody would want to put a complicated GPS into their cars” ha ha. Famous quotes not withstanding. ;)

How did you build this before arduino?

@@ianhayden2839 I used the PIC 16 series of chips. I did the first one on assembly language then converted it to ME Labs PIC Basic compiler. The first chip was the 16F84 then I went to the 16F877 for bigger memory. It was about the time when China started making mouse shaped magnetic mounted GPS units that had serial communication IO and were much cheaper. The first one had a very expensive GPS module. I used a Nokia phone as the GSM interface as they had the easiest IO on their edge connector. Later I used the Siemens phone because it was cheaper , then a company came out with a modular GSM device that was a bit cheaper but more importantly, was able to be mounted to a case far easier. I forget what the company name was but I still have one of them in my “junk box”. I had fun making it & the spin-off projects too. Spin-offs we’re a house alarm that would notify you about power failures and any alarms. You could patch zones and reset the unit. You could also switch to audio communications & listen to your house to see if there were unusual sounds coming from there & trigger the siren , call the police or a combination. Another spinoff was a weather station that could be polled by anyone using SMS. I called it REMWEX. PIC BASIC PRO was the enabler. If it was to be assembler for the later projects, it would have been far too tedious. There were C compilers but they weren’t aimed at the hobbyists so they cost more. I didn’t have too much free cash back then so I was constrained. When the Arduino showed up, I resisted a bit because you couldn’t read protect the firmware. Now I just don’t bother about that. I’m old enough now to know that Karma will need to be the one that sorts out those that steal firmware. I just don’t have that fight anymore. I hope this has been informative. So many people here have no idea what others are capable of doing that they simply tear down the poster because, from their limited experience, the claim appears outrageous. As I said before; I’m too old now to care about uninformed opinions of people that haven’t the skills to do the things I’ve done. Thanks for asking @ianhayden2839. Regards Peter ~ not knowing has never stopped anyone from doing anything. That’s my own saying that I’ve lived my life by.

Hey, thanks!

Thanks for the feedback :-) I actually already did a video about pretty much every communication protocol ;-)

Glad you enjoyed it!

My favourite too ;-)

Thanks a ton

Thank you so much :-)

This!!!

It's really hard for makers such as myself that have limited electronics experience, are used to using dev modules, to even know where to start scaling down their big, fat prototypes!

He didn't do much for miniaturization. Taking those circuit designs and combining them into a custom PCB with optimization for every component could easily make that fit in your pocket, probably small enough for a dog tag. Your cell phone has the same functions plus 10 million more and it fits comfortably in your pocket. He basically built a cell phone from 2010. Those have always been much smaller than that boxy thing he built.

Thanks!!
