Very nice. You could include an accelerometer also and then use the signal from that to trigger a call, giving you a security system you can buy on your bike!
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.
The SIM800 moduls are extremely susceptible to unstabel power supplys. Short wires and an extra decoubling capacitor right next to the modul is necessary. The modul draws around 3A while comunicating with the base station. Had to learn it the hard way with hours of debuging.
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

Nice to see someone making the thing I made back in 1995. I tried to sell it but, I was told by marketers and security companies that I had made a useless device that nobody would be prepared to buy it. I think I was just too early with the idea! I also did a GPS vehicle tracking system and alarm also rejected as “far to advanced for anyone”! Good ideas need to be at the right time! 26 years later seems to be about the right time.

Hey Scott, long time viewer of your channel, I was watching this video and thought to myself, man this will be great, it will be tiny and everything will fit in the palm of your hand, then I saw the printed box was the finalization and understood, 'small' is relative. If you ever revisit the topic, I'd like it if you talked about the miniaturization of prototypes in the development process, including what challenges you came across while attempting to miniaturize this project. Thanks!
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.
You can put this in a car in case it gets stolen and send you or police the gps location. The only small issue is that SIM cards do cost a monthly subscription to use, around $12.00 US dollars a month. But I do enjoy all your videos!
Another option would be to use the "free" sim cards some ISPs provide to their costumers. Depending on your contract, they mostly come with a very small amount of data/free SMS (like 200 MB or 50 SMS/month) but this would be more than enough for this project.

I love taking COTS boards and piggybacking them on to a custom PCB for small scale production. Then to go full scale production, you'd have to take all those boards and make it into one "auto pick and place" capable design so it could be mass produced and sent through an oven by the hundreds... Also to make it more like credit card sized and lower power consumption, and a sleep mode on the GPS until the button is pressed, etc...

kinda tried it but the boards don't have enough interfacing options and not enough datasheet information available online. and trust me its way easier this way and go with PIC boards and industrial sensors but then it becomes a complete project and not DIY.
5:41 - You were not removing the Simlock, but PIN authentication I presume. The Sim-Lock is normally installed in a phone to prevent the using of foreign providers.
I think for the last location part it is possible by just updating the software a bit. Each time the GPS location is fetched, we store its state. By determining the GPS output has become garbage or not valid (depending on the GPS output), then we could use the last good state and its timestamp. Then when sending it, we could also send the sending timestamp so it contains our last known location, the time and the distress time. As for the smaller part, I think it's only possible by creating a custom board with everything integrated on it.
both are possible, the remembering gps data would be all code part, but the making it smaller would include a custom board design, a little more difficult, but definitely possible
I think one of the main ideas behind the neckless is the ability to send an SOS without alerting your attacker that you are doing so. Clutching a neckless is a common "comforting" action someone might instinctively do when experiencing anxiety and/or danger. So an attacker might not recognize the victim is calling for help. So maybe there is the possibility of some projects involving miniaturization and/or concealment of devices like this. Cool project, I learned a bunch.
Necklace. What is it with people not seeing the difference between, for example, your and you're, or were and where? And it's almost always native speakers.
I would upgrade the software so that it logs every 10 mins the gps position and save them to give with timestamps, so that it could be still usefull if the emergency is occurring indoors.
You can get rid off power slide Button and keep only one push button. Push it > arduino wakes up > and keep power by logical output and transistor. When everything done - arduiono turns off transistor and it’s power (completely)
I would use a soft switch transistor circuit. The button activates a transistor that powers the Arduino which then latches its own supply and can turn itself off on completion. Reduce power usage.
Now I know how to build a real autonomous "safety necklace" * just in time for Christmas ! I hope my girlfriend will like it. *You forgot to put a loop to pass the chain through in your 3D printed design. 😜
That's a rather large necklace 😅. If you want to make it compact you're going to need a 2 or 4 layer custom PCB with bare camponents on either side. Also, minding the power usage, all those small regulators would need to be replaced by a single psu circuit
I was thinking he just built himself one heck of a necklace medallion, all he needs to do now is find a strong enough necklace so he could "inconspicuously" wear it :) Joking aside, this was way easier to follow for me than his usual electronic circuits. I was amused hearing him say "ZIM" card :)
Good idea, I like this, I will probably build it for a friend of mine as a hand made Christmas present. If used with a MOSFET the mercury switch will allow the circuit to consume no power at all until it's triggered

stacked boards is such a cool method
5:41 - You were not removing the Simlock, but PIN authentication I presume. The Sim-Lock is normally installed in a phone to prevent the using of foreign providers.
Might be worth enhancing it to remember last GPS position, so that if used inside, the building location is known.
Any way of making it smaller?
I think for the last location part it is possible by just updating the software a bit. Each time the GPS location is fetched, we store its state. By determining the GPS output has become garbage or not valid (depending on the GPS output), then we could use the last good state and its timestamp. Then when sending it, we could also send the sending timestamp so it contains our last known location, the time and the distress time.
As for the smaller part, I think it's only possible by creating a custom board with everything integrated on it.
both are possible, the remembering gps data would be all code part, but the making it smaller would include a custom board design, a little more difficult, but definitely possible
Nice new intro man!! Much better than the old ones. And, as always, the video was exceptional...
Wow sir your efforts really deserves to be appreciated 👏
Thanks a ton
i love the intro!
This would be good in a old pager case
I think one of the main ideas behind the neckless is the ability to send an SOS without alerting your attacker that you are doing so. Clutching a neckless is a common "comforting" action someone might instinctively do when experiencing anxiety and/or danger. So an attacker might not recognize the victim is calling for help. So maybe there is the possibility of some projects involving miniaturization and/or concealment of devices like this. Cool project, I learned a bunch.
Necklace. What is it with people not seeing the difference between, for example, your and you're, or were and where? And it's almost always native speakers.
@@TheRealDrae If YOU’RE trying to criticize my use of YOUR, then YOU just had an epic fail because YOUR is correct in the above post. 😜
Woah a lofi feeling intro. Sweet!
That's craaazy, I know the girl who made that company she's a computer engineer from UMass Lowell. No idea her startup got that big
Comedy has been improving over the years. Keep it up man!
The new intro is really cool! Excellent video as always
Thank you very much!
WOW, the new intro, as I said, still remember the blue one!
I would upgrade the software so that it logs every 10 mins the gps position and save them to give with timestamps, so that it could be still usefull if the emergency is occurring indoors.
I love A-ha's "Take on me" music video, loved your old video intro, I don't think combining the two is such a great idea.
The new intro is as great as this project itself! Thanks!
Exactly what I wanted a while ago
5:24 Just reminded me about electroboom's channel
nice intro, love the classic music but feels soo much different
Those companies trying so hard to make him buy it instead he makes his own btw nice intro
ANYTHING TO AVOID ONE OF THOSE MLM/Pyramid Scheme PITCHES!!!
Awesome build man!
Can't tell you how much easier building circuits is now that I've found your channel
You can get rid off power slide Button and keep only one push button. Push it > arduino wakes up > and keep power by logical output and transistor. When everything done - arduiono turns off transistor and it’s power (completely)
Love it 😅😅😅 specially the "get the heck out of here mode"
My favourite too ;-)
Thanks, that you explain the Code. Really helpful
I would use a soft switch transistor circuit. The button activates a transistor that powers the Arduino which then latches its own supply and can turn itself off on completion. Reduce power usage.
i only clicked for the "getting me out of awkward conversations" part of the title and didn’t really care about the save your live part lol
Now I know how to build a real autonomous "safety necklace" * just in time for Christmas !
I hope my girlfriend will like it.
*You forgot to put a loop to pass the chain through in your 3D printed design. 😜
I like how you say "zim" card ❤️❤️
That's a rather large necklace 😅. If you want to make it compact you're going to need a 2 or 4 layer custom PCB with bare camponents on either side. Also, minding the power usage, all those small regulators would need to be replaced by a single psu circuit
I was thinking he just built himself one heck of a necklace medallion, all he needs to do now is find a strong enough necklace so he could "inconspicuously" wear it :) Joking aside, this was way easier to follow for me than his usual electronic circuits. I was amused hearing him say "ZIM" card :)
First video I've seen in a while, I like the new intro, fun little project too, good to be back cheers
Hey, thanks!
This is awesome. Amazing as usual
You could consider swapping the Arduino for an esp to enable location indoor matching wifi with hard coded locations if you wish so
This is a cool project. Unfortunately we have no 2G services in Australia at all now and 3G are even being turned off soon
New into looks great
Change the switch for a simple mercury type switch on my motorbike and I get an alarm if anyone tries to tamper with it or raise it up to steal it.
Good idea, I like this, I will probably build it for a friend of mine as a hand made Christmas present. If used with a MOSFET the mercury switch will allow the circuit to consume no power at all until it's triggered
Very creative, entertaining, and useful
Yeah, those pyramid schemes chats.... This is exactly what i need :D
7:12 I hope that this isnt ur actual phone number :D, Nice one !
I want one! Don't know why as I know I wont ever use it, but still want one. Brilliant. Great video.
Loving the new intro! Familiar, yet fresh and very stylistic.
LOVE the new intro, heck yeah
I'll be honored
