I wish rak made something like this with a E-ink display the battery life would be insane
It's probably that ESP32 system that's chewing up the power. Trying to find someone who's got power consumption numbers for the RAK solution (to which you can add interfaces, supposedly) vs the Raspberry Pico solution. Don't know where the Pico usage falls on the scale of consumption rates.
@@suzyamerica4679 my RAK4630 node pulls ~15ma without GPS at all. A couple ma more with the gps installed but disabled in software. With gps enabled it’s around 60ma.
Hopefully an e-ink display and interchangeable antennas in the future! I'm excited at what they're coming up with for these devices, I _really_ want to see an old t-mobile sidekick like device with e-ink display that slides up to reveal a hardware keyboard underneath, or can be used with bluetooth from your phone like lilygo
Those would be awesome upgrades!
Honestly Meshtastic is just getting started. I'm looking forward to what the future holds.
I just made a video about T-Deck. I'm loving it! Meshtastic is amazing.
The T deck form factor with the e ink screen would be perfect for battery
Thank you for sharing this stuff. Saw a comment on the main meshtastic discord about a device like this with AlleyCat's case. With a 4200mah battery he said he was getting about 24 hours use out of it on a non-busy network with fastest screen timeout. Given its power consumption, kinda makes sense to make a deep case with a substantially larger battery and maybe a solar panel on the back. Flip it face down when not in use, let it grab some watts from the light.
Edit: the user AlleyCat seems open to people remixing her design, which is cool :)
You can buy 18650 with 4200mah right? I believe the even go higher than that although there are counterfeit batteries & I don't know where the real deal ends & the fakes lie into.
Someone should make a case for that.
@@ClickClack_Bam Eh, I'd be tempted to put a 10+ah lipo pack in, and, under something clear that can take a little abuse, a 6v solar panel on the back. Every mah counts.
They need to do a duo with rtl-sdr!
I am getting 5 hrs with moderate use, with the 1100 mah battery. I have a second T-deck that will have a 3000 mah. If you get stuck on the pre programmed message response screen use the touch screen to navigate. The mouse get locked on the screen until you send a message. You can turn on and off the keyboard backlight by pressing Alt + B at the same time.
Thanks.
That seems like a really bad power consumption setup.
Why does it chew through battery so much?
LoRa is low power I thought right?
@ClickClack_Bam I have not performed any recorded testing yet. However, I am getting 4 to 5 hours of use on my current battery setup. It would definitely be better with an E-reader screen.
@@RavenwoodAcres I imagine they'll be working on upgraded software that might possibly add time to the battery.
I'm just scratching the surface on the Meshtastic comms.
I'm excited for this though.
It seems like the idea of network free, secure communication is here & it should get better & better from here on out.
Cool concept. Would be great with a NRF board, paper screen and if it could store more than 1 message at a time.
An e-paper screen would be great.
It has a nice full color screen, but I assume it’s not active to save battery. If the screen had the look of the Android or iOS app, it would awesome.
Nice video. Remember, you're going to want to leave some room for a lithium battery for heat, and just in case, for swelling. Otherwise, things could get very ugly, very quickly. Remember, this is something that fits in your hand.
This looks like a good meshtastic device to have a couple backups of because personally in the past during ice storms is when internet goes down and theres no way for anyone to download an app.
It’d be nice if there was a local web interface that mimics the android and/or iOS app.’s Then in theory multiple devices could send messages over a single LoRa device; with a caveat that all devices connected to a single lora device could only see and send a single message at a time from the same dashboard. But at least the lora mesh could be utilized at/on a whim without needing prier internet access.
Good thinking
That intro! I was like, wtf are you talking about!?🤣🤣🤦🏼♂️😜😉
I knew that old would come in handy some day, 😆.
With that groove connector you can solder a m100 mini GPS directly to it for use with a case or use a groove connector with a modified case.
That is my next mod.
I think that's the same keyboard as the old Blackberry Q-10, I had one and then the Z-30.
"The problem with this you need one of these" ah yes.
That "unknown" port could be used to attach a GPS that uses a serial interface.
That would be cool.
It is. The chick at the 'Random Alley Cat' channel has a video of her installing one.
it is. I just soldered my gps chip onto that spot and its works perfectly
The 3D printed case is really beautiful, I think you should use 3d printed threaded inserts.
That would definitely make it stronger.
nice
It seems designed for gorila comms. No logs they can check or message time if they capture you, no GPS so location can't be hacked, standalone device, no e-ink that will show the last message.
Could also be great for drug traffickers. "Yo coast is clear, bring in the boat".
I'm wondering if LiliGo T-deck could be used to create something like SpotX - basically to mount a sattelite antenna, and work on 240-270MHz satcom (ufo10, ufo2, ufo11) or even TinyGS LoRA sattelites on 70cm frequencies??? Could be the perfect very-long distance device for SHTF scenarios that even my Mom could use.
I hadn't though of that. It is a very interesting idea that deserves some research.
@@RavenwoodAcres Yeah. Basically, the Meshtastic tranceiver would need to be replaced with (or complemented by) something that would work on 240-270MHz and/or TinyGS frequencies - that's the difficult part. It would obviously need a satellite antenna (that's easy: Brazilians and Russian have perfected the art of compact homebrew satcom antennas).
And it would probably need a user-friendly WhatsApp/Telegram-like app written (provided that T-deck comes with some sort of OS preinstalled), which would assign a fixed 5 or 6-character username to itself and listen to the train of 187-character transmissions (like AIS does) and save the ones that start with it's own 6-char username, and display accordingly. Once received, it sends out a receipt ping. Once read by recepient, it sends out a read ping. No central server. No database (the local DB is inside the device itself). No authentication gateway or gatekeepers (those Iridium, Garmin or SpotX devices will not work during SHTF even if you have subscription because the authentication gateways are on the ground). Just a set of hard-coded rules: e.g. 140-char max, 10 messages/hour max; if not received after 5 minutes, try again - 5 times max; and what to do if the primary frequency is hijacked, jammed or overloaded.
The structure of each 187-char message: @To, @From, message-ID, 140-char Content, Timestamp, Message-status.
According to my calculations, if 10,000 people were to transmit 187-character messages in 1 hour that's just 2.2MB/hr
You are not going to be working milcomm sats with this device.
Is the 915mhz the one to buy for USA use?
Yes
How big of a battery will your 3D printed case fit? I was planning on getting a 3000 mah so that I'll be covered for a few days.
If you print or get the v2 case the battery case dimensions are as follows. 54mm x 34mm x 13mm deep
Voltage? I can't find it anywhere. 3.7V ?
3000mAh will work for ~18 hours in an environment where there are not many LoRa messages being passed. The more messages that are passed, the lower your battery life will be.
I wonder if you could just add one? Like a NEO-8 to the serial port.
Good question, I am not sure.
Yes you can. The lora module uses SPI, so you should be able to take the 2 spi lines off that (MISO, SCK) and use one of the Grove tx/rx lines for the address line, to get a 3wire spi connection to say a 2.9" eink display.
The firmware then bneeds to support the display by changing the address line and recompiling
What is the operating input voltage? I can't find it on the lilygo website or the github or the support page. And if I'm not seeing it, and it's there - please give a link to that so I can see what the heck I'm doing that I can't find the info... thx
I would say 3.7 to 4.2 volts. However, the max input should be around 5 volts for charging.
@@RavenwoodAcres Thanks for the reply. I kept looking and found an similar answer as well. Weird that it's such an elusive question and answer...
I totally agree with you. RAK wireless is way better at publishing their specifications. My numbers came from the OLED display readout because I couldn't find any published info.
whats the stick off the tbeam?
I added an external antenna. ua-cam.com/video/odsQVLUPgys/v-deo.html
Sold out. Here's hoping it comes back up for sale.
They're available on AliExpress in the 915mhz which I believe is the correct one for USA use.
@@ClickClack_BamYe, US is 915Mhz or 2.4Ghz.
I bought directly from Lilygo in China, took a couple weeks.
3d file dose not exists?
Yeah the creator lull his file. Here is the one I recommend now:
www.printables.com/model/741124-lilygo-t-deck-case
I had to google the Lilygo T-Deck just to now what the heck this thing is. I guess this video is only for certain people in the know. Otherwise you might want to explain things to if you want new viewers.
Thanks for watching. I have a playlist that details LoRa Mesh Communication devices and their functions. LoRa Mesh Network Communication: ua-cam.com/play/PLDwfLFrunJ3JvQba9ShNxHkcnpU2u4G_y.html
It’s basically just an ESP32-S3 chip with a display, keyboard, speaker LoRa capabilities and a few other goodies. Everything you can make using an ESP32 development board integrated into one package.
Their basic options (without LoRa) would be something like the T-Display S3 which is the ESP32-S3 a display, two buttons etc. they’re all pretty much the same. Just ESP32 micro controllers with added hardware.
You’ll find this is the case for 90% of the electronics community. It sounds like OP probably has good reason to not explain, but it is seriously almost impossible to find videos on anything that just tell you what the f%#^ something is and what the f#%^ are some cool things you can do with it.
ESP32 RUSTED ON T-DECK!!!!
why not just connect it via bluetooth to a phone, you already have a screen
That is always an option.
@@RavenwoodAcres im super new to these, really interesting concept will definitly set one up
@edumacat3d Outstanding, welcome to a very cool community! I have a good LoRa playlist on my channel you can check out. Additionally, I would recommend The Comms channel. His videos are great and very informative.
that‘s what the t-beam is for
It would be a good option if you want increased privacy or isolation from tracking/logging.
