make a custom case to hold all the motherboards of all the playstation consoles. ps1/ps2/ps3 and ps4. one box, all original hardware.

[@nikkopt]

Just discovered your channel because ESP32 retweeted one of your tweets. I really like your setup.. very pleasing for the eyes. Your bench is very well lit. No camera shake, etc. Keep up!

[@vng]

Since it has a GPS, you can use the transmitter to send its GPS position, and use the receiver to calculate the distance between the received position and the receiver's GPS position.

[@ProtoG42]

V Ng I had thought about that. Maybe I’ll use the haversine formula in the code.

[@tonybrandao4681]

nice overview, wondering what kind of power consumption you're getting with LoRa and GPS enabled. Thinking of using these for light industrial use , and wondering if using the ESP32 deepSleep and waking every 1 hr the 18650 would last a reasonable time?

[@urbnctrl]

You get approx 24h use time from one battery charge. Solar or usb extends the use time significantly

[@ats89117]

Great video. Thumbs up and thanks for the reference to the new board. One recurring issue though is that a lot of the antennas that are out there are actually not even close to being tuned for the band that they are supposed to operate on. I wonder how well the antennas on those boards really work at 915MHz? Of course your testing indicates that they are at least reasonably usable, but it's possible and probably even likely that there is a lot to be gained with a well matched antenna...

[@ProtoG42]

I may end up trying some directional antennas.

[@garybeech2234]

Thank for your video and code. Which IDE did you use to compile the code? I tried the Arduino IDE with EPS32 addition to compile the GPS code and got errors Thank you Gary

[@erics2860]

I’ve been trying to figure out for like a half hour now what the hell the application for this would be other than a regular esp32

[@terryphan7451]

Gps tracker over LoRawan is one of them.

[@mohinderkaur6671]

Great video! Was very helpful!

[@emanuelvillanueva9041]

How long did work before you had to recharge the battery?

[@catobandito6623]

How do you set up BT without the device having a screen?

[@adammichalk8401]

Hey, i want to buy the TTGO T beam for aprs, but i need 2 one for the igate and one for the tracker, and i want to buy one and make on.The diy one will be made of an gps32 an gps module and a 433mhz lora module.Do you think that i could use the aprs code for the t-beam on the diy one?

[@chichin56]

I am looking for a way to use this card for a surveillance camera with a camera from a laptop. what will be the coverage of the wifi antenna of this module. gracais Saludos desde Colombia.

[@XXandresilvaXX]

Hey, i'm using the ttgo t-beam board and i wanted to ask u somethings. How can i contact you? I've tried to message u on instagram though

[@guillermo7133]

Hi. I have problems initializing the module “DollaTek LORA32 433Mhz ESP32 Sx1278”. It is a clone of the TGO LoRa32 SX1276 / 78 module. I cannot initialize it with the library . There are problems with the pins. However, I can initialize it with the

[@ClaudioBarca]

Can I connect this board with a GPRS module to send data via HTTP (es. Thingspeak) the LORA received data ? If yes what module can be use ? Thanks

[@triplettjon]

what core are your using as i'm trying the gps.ino and getting uart serial errors i'm using the t-beam board from dl.espressif.com/dl/package_esp32_index.json 1.02 version and having issues running the default sketches i'm just trying to get the basic gps to display on serial and not having much luck:( getting "core\core.a(HardwareSerial.cpp.o):(.bss.Serial1+0x0): multiple definition of `Serial1'" which tells me that some thing is screwed up in my core files"

[@MuertoChango]

just a heads up the display pin outs from the one I got have ground and vcc backward

[@adrianomoura2010]

hello good afternoon sir! I would like a help with a esp32 ttgo I bought but I can not load the code for it. he came ocm softrf installed

[@muhamadiqbal9926]

Hello I am from Indonesia. What is the range distance from Lora ?

[@marcelocheves]

Thanks for the overview man, do you know how many free pins left on the esp32 for I/O use? thanks.

[@showmequick2245]

you don't really have how to on instructables site. all you have is clock setup but not exactly how you accomplished the packet count. could you share that please ? thx

[@showmequick2245]

Nevermind please. just saw your google drive share.. Thank you so much.

[@nikolabalint1314]

Hi, does this firmware works on version v.1.1 of boards? And can you change transmit power?

[@th0m]

How do you have your iFixit kit set up to stick or hang on your bench rack like that? I was just thinking about trying something similar yesterday and happened to stumble across this video

[@clayton9136]

Zip ties. Hot glue magnets on the back.

[@RodrigoCarbajales]

Did you try to go into sleep mode and low power consumption on GPS?

[@daslolo]

what OLED are these? all the ones I've had have VCC and GND reversed

[@ProtoG42]

These are the displays I have: amzn.to/2LEC2LD

[@christophercobb4317]

I have a question I purchased the ttgo I soder every thing then i connect the antenna and power it on red light blinks but the screen is not powering on do you have any advice

[@crazymohawk86]

Where exactly did you solder the display

[@jamesotisjr2322]

I just had a revelation in this regard: 4 of my TTGO T3_V1.6 ESPs require /dev/ttyUSB0 as a com port. 4 others did not work, and a TTGO Meshtastic GPS LoRa ESP refused to communicate with the computer. Then I tried connecting via /dev/ttyAMAO. it appears that Lilygo switched from CP2102 serial chips to CH340s at some point. open up your IDE without the ESP plugged in, see what ports are available, then plug in the ESP. either /dev/ttyUSB0 or /dev/ttyAMAO will show up. use that port. anybody knows where the I2C port pins really are, speak up, please

[@cluberic]

Could you at least show how to program it....

Hi, Can I charge the lypo while is in use?

how you get higher rssi?

[@MichaelTeeuw]

If only they had 3G as well ...:)

[@RobertSzasz]

This is a cool project, links for the boards and screens?

[@ProtoG42]

Thanks, I just added it above in the pinned comment.

[@nicholasthon973]

KZbin’s Andreas Spiess got 200km on his with a proper set of the little antennas. Sounds like yours aren’t the right ones.

[@ProtoG42]

His videos are great but that was direct line of sight and a world record that he broke by carefully choosing the two highly elevated points. He also had to use the SF12 reduced data rate of 250bits/s to accomplish that range. Depending on your application, that may not be acceptable. The example from the video is using the default data rate of 11,000bit/s which is a lot more data and the default transmitter power. The SF12 he used is also a much longer transmitted pulse than the default SF7 which will give you better range at the expense of max payload. You could definitely use better antennas than this but there are a lot of options for improving range through software. You can adjust TxPower, Spreading Factor, and Signal Bandwidth as well as other configurable settings.

[@aclkeba]

Just got myself 2 your videos are bad for my wallet....

[@ProtoG42]

Anthony Keba haha they’re bad for mine too :)

[@skaardd]

why is there not a single damned video of how the oled install goes?

[@blizzardfpv9584]

like the video thanks

[@XenoContact]

Looks fancy but what it is this good for?

[@ProtoG42]

It is a microcontroller with WiFi, Bluetooth, GPS and a long range radio transceiver. There are countless applications for something like this. Sensor networks, robot controllers, gps locator beacons, and so on.

[@XenoContact]

Oh I see, now that sounds very practical ! Would the radio transceiver response time allow for it to accurately drive an RC plane over long range(>20km) ?

[@ProtoG42]

Yes, Team Black Sheep Crossfire uses LoRa for longe range RC flying.

[@cptfbi]

bought 2 of these to play around with Meshtastic.org

[@jaydmatacarita]

What's the range on these.
