ESP8266

Archived from radmon.org - originally posted 28/01/2023 A member (of radmon.org) asked me if the Gamma Scout would/could work with radmon.org using the USB and software the counter came with. The answer to that is a simple, no, but it could be down with a quick hack. Simply add a couple of wires and connect them straight to an ESP8266 or similar MCU. This guide only covers the 'Alert' model. There may be differences with other Gamma Scout models. Here is how: Open up the Gamma Scout and locate the small transistor at the top left of the board, right above the pin header. There we are going to

This is bare-bones code only. It does only these things: receives pulses on GPIO 13 (physical pin D7 on Wemos D1 Mini), calculates CPM and submits it to Radmon.org (via WiFi) every 60 seconds. It has a little debugging that can print to serial, flashes the internal LED when an interrupt event is detected and I have also added CPM print to serial (much like the NetIO GC-10) that can be used with

Archived from radmon.org - originally posted 20/12/2021 [Updated: 22/12/2021] Its the first day of holidays and I'm bored already.... So I cooked up a neat wifi/wemos d1 mini/arduino/LED display for displaying a station's current CPM. It works by simply connecting to one's Wi-Fi and then goes to the URL, pulls the data, strips the first space and everything afterwards then converts what is left to a float (the CPM count from the start of the string) and displays it. The bar graph LEDs are mapped from 0 to 100 CPM at full scale deflection, but the 7 segment display will display up to 999.9
