Badge Modem

Connecting on wireless network and BBSing made on Hackaday Conference badge

Similar projects worth following
Badge is from 80' . In that time popular was BBSing era before internet for communication, etc...

Badge is communicate via UART to NodeMCU but you can use other ESP8266 chip. Modem communicate with AT commands.

My plan is to make shield for pins where you can just plug and play Wireless Card.

I will use PCB service from Seeed.

Seeed Fusion PCB Assembly Service offers one-stop prototyping for PCB manufacture, PCB assembly and as a result they produce superior quality PCBs and Fast Turnkey PCBA from 7 working days. When you prototype with Seeed Fusion, they can definitely provide Free DFA and Free functional tests for you! Check out their website to know about their manufacturing capabilities and service.

    Here is schematic of prototype version 2 of BadgeModem. In this prototype i was use ESP-12F and test was successful. I made it to be just simple plug and play. 

    Simple add modem to badge, load program and thats all.

this device can use modem:

*phone land line rj

*sound modem similar http://www.whence.com/minimodem/ or https://play.google.com/store/apps/details?id=com.aicodix.rattlegram 

*irda transmision

*cc1101 or(and) lora for emergency (reticullum or meshtastic)

* 1 wire cable transmission, and rs232 ?

This will be great.

Super cool! I did similar for SuperCon 2018! It's super cool to seem to have managed to control from BASIC. That was one of my goals but lack of string support hindered that. We ended up writing a companion 'app' for the Badge as well as ESP32 firmware.

I cant add in this badge, but with external arduino i can do that, with serial communication to MicroModem you can communicate with APRS example.

I dreaming about emergency device , one, mobile, with power (meybe solar , 18650 and or AA)

  Are you sure? yes | no
