The remote display is a companion kit to the APRS weather station. It will receive weather and telemetry information from your weather station over the APRS-IS system. A version using an IoT service is in development for people not holding an Amateur Radio license.
Assemble the Kit:
- Press the female headers with the short pins onto the pins of the display then set the D1 Mini onto the short header pins. This way everything will be nice and square.
- Make sure the silver 8266 “can” is on the side that faces the underside of the display.
- Solder the pads on the reverse side of the D1 Mini to the headers.
- Cut the wire in half and skin the ends. Bend hooks in one end of each wire and solder the hooked ends to the pushbutton terminals. Solder the other ends to the GND and D1 pads on the underside of the TFT display as shown in the photo.
- Make sure the D1 Mini is in the correct orientation for the display: RST to RST, TX to TX, etc.
- Supply power to the display from a common USB adapter and Mini USB cable.
- You can put the display inside the box supplied with the kit. Cut a hole for the Mini USB connector with an Exacto knife and drill a 5/16-inch hole for the pushbutton. Make sure there is space under the display and beside the D1 Mini to mount the button. Wrap the button terminals with a bit of electrical tape to prevent shorting with the display or D1 Mini.
- Micahel’s carries a small wooden box with a glass window in the lid. It would make a nice enclosure for the kit.
Configuring your APRS Remote Display Kit:
- The firmware is preinstalled. All you need do is send it your weather station information and logon credentials for your Wi-Fi.
- You must be near a 2.4 GHz Wi-Fi router and know the SSID and password.
- You must have a Wi-Fi capable laptop or smartphone.
- Watch this video before entering the following data: https://youtu.be/uLgqKbZDVDw
IMPORTANT CHANGE: Use ET instead of EST. The device recognizes ET, CT, MT, PT, AKT, and HT.
- Since you have a working weather station, use may use your station’s SSID or you can use my station as suggested W4KRL-15. You will need to enter the following information:
- Your Wi-Fi SSID
- Your Wi-Fi password
- Your callsign with an unused SSID from 1 to 16. For example W4KRL-15
- Your APRS-IS passcode. https://apps.magicbug.co.uk/passcode/
- The callsign of your IoT Kits weather station: W4KRL-15
- Enter the filter for your station, for example b/W4KRL-15
- Save the configuration.
- The screen changes every five seconds. The weather and telemetry will appear within 5 minutes.
- If you have an APRS-enabled transmitter you can send a short text message to the kit using the unit’s SSID. The message will stay on the display until you press the button.
If the unit cannot connect to Wi-Fi it will go into configure mode as indicated by rapidly flashing LED on the D1 Mini.
If you want to change the time zone or other parameters, you can force configuration mode by pressing the D1 Mini reset button twice within two seconds.
