synopsis
Modify the famous Motorola Advisor (from the movie Hackers) so it listens to the LoRa band.
ingredients
- Motorola Advisor I with single AAA battery
- RFM95 SX1276 module with helix antenna
- step-up (boost) converter to 3.3v
- Arduino pro mini 3.3v
- RSS.EXE (for resetting password) and ADVISOR.EXE
- optional but advised: programming jig with pogo pins
- AdvisorRadio.ino that translates LoRa messages into POGSAC 512
Basically, Pena Sarajärvi did all the heavy lifting back in 2021[1]
information snippets
external pager header pinout:
- TDO (RxD) top
- RDI (TxD) middle
- GND bottom
2400 baud 3.3v (probably 5v tolerable)
pinout of the mini header inside the pager (small pitch, maybe 1mm):
- B++
- GND (connected to Arduino, RFM95 and step-up converter)
- B+ (connected to step-up converter)
- LIM_DATA (connected to Arduino)
- A0/SDI/MOSI
- A1/SCK
- A2/SS (connected to Arduino)
- NC/Audio
command to send a message using LilyGO TTGO LoRa32 868MHz ESP32 with a better antenna, running OpenMqttGateway 1.8.1:
mosquitto_pub -h <IP> -t "ackspace/OMG_ESP32_LORA/commands/MQTTtoLORA" -m '{"message":"0118999:Hack the planet! "}'
result
really jank jig
separate parts
LoRa module in place
Some notes:
- the range is a bit disappointing: successful transmission at a little over 100m line of sight using default settings on both pager and 'gateway'
todo
- files and commands
