VFD output for the GeigerCounter
GeigerVFD is an open-source printed circuit board by muccc, from the muccc/GeigerVFD repository on GitHub. It is a 2-layer board of 117.3 × 109.7 mm with 74 parts on 79 nets, routed with 632 tracks and 26 vias.
It is built around the LM2577S-12, TLC555N and JUMPER3, with the BD137, BYG23M and STN0214 among its other parts. Its parts include 24 resistors, 15 capacitors, 9 diodes, 6 ICs and 4 connectors. It belongs with the lEDs and displays boards and the ESP32 boards of this library.
This repo is a collection of all the parts to build an ESP32 based handheld device to measure radioactivity with a Geiger–Müller tube & display info on an VFD.
Future plans are Home Automation integration, logging radioactivity measurements over WiFi & displaying additional information like e.g. a Clock.
The device is be powered via Micro-USB port of the ESP32. Note that the current draw of the VFD may exceed the 500mA USB standard.
The PCB is designed in KiCad. All source files are in the pcb Subdirectory.



The Case is designed in OpenSCAD. Sources reside in the case Subdirectory.

:warning: Work in Progress :warning:
The firmware is written using Espressif-IDF and lives in the firmware directory.

It measures 117.3 × 109.7 mm and has 2 copper layers, 1.6 mm thick.
74 parts, built around the LM2577S-12, TLC555N, JUMPER3 and BD137. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the muccc/GeigerVFD repository on GitHub, at the commit this page was made from: the board is pcb/GeigerVFD.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask muccc before reusing the design.
