Overview

CosmicWatch ventidue is an open-source printed circuit board by RedNicStone, from the RedNicStone/CosmicWatch-ventidue repository on GitHub. It is a 2-layer board of 102 × 113 mm with 123 parts on 100 nets, routed with 710 tracks and 306 vias.

It is built around the TEENSY 4.1, BMP280 and TCR2EF, with the BAS70XY and DS3231S# among its other parts. Its parts include 33 capacitors, 33 resistors, 21 connectors, 8 ICs and 6 diodes. It belongs with the NXP (LPC, Kinetis, i.MX RT) boards of this library.

CosmicWatch Ventidue

Continuation of the original CosmicWatch project by Spencer featuring many improvements and additions.

What's new?

CosmicWatch Ventidue's new features are plentiful so here is a quick summary:

  • Flexible design that allows connecting either one or two detectors
  • Built in on-silicon coincidence detection between the two modules
    • Time resolutions from 5ns down to just 1ns [cooling required]
  • Powerful Teensy 4.1 microcontroller
  • Full color 1.5" OLED display with great user interface
    • Rotary encoder for easy navigation
    • Buzzer for audible counting and interface feedback
    • Custom rendering library for maximum performance
  • Optional solder-free support for multiple prebuilt sensor modules
    • GPS, Pressure, Humidity, Temperature and RTC supported
  • Built in Ethernet module for intra & intercommunication
  • Improved mechanical stability and 3D printed casing
  • Interrupt driven software architecture for accurate counting and a responsive user interface

Hardware SATE [blocked]

A first prototype has been produced and tested. We are currently busy on fabricating a newer board that will be tested as soon as finished.
There are plans to provide a kit with a pre-assembled board for purchase once hardware development has sized.

Software SATE [blocked]

Software is currently undergoing heavy development and is only barely runnable.
If you do want to take a look check this folder.

The following modules have been written so far:

  • Custom rendering pipeline
  • OLED driver [Needs push to support DMA]
  • On-chip coincidence detection
  • Example for testing peripherals

The following modules still need tending:

  • True type font rendering
  • UI and windowing system
  • Data acquisition and storage
  • Ethernet communication

Any help is much appreciated!

Questions

How big is the CosmicWatch ventidue PCB?

It measures 102 × 113 mm and has 2 copper layers, 1.6 mm thick.

What parts does the CosmicWatch ventidue use?

123 parts, built around the TEENSY 4.1, BMP280, TCR2EF and BAS70XY. 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.

Where can I download the CosmicWatch ventidue KiCad files?

From the RedNicStone/CosmicWatch-ventidue repository on GitHub, at the commit this page was made from: the board is kicad/CosmicWatch-ventidue.kicad_pcb and its schematic kicad/CosmicWatch-ventidue.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the CosmicWatch ventidue design in my own project?

Its repository states no licence, so its author keeps all rights: ask RedNicStone before reusing the design.
