DVTI Camera Wiki

Project overview

The goal of the DVTI camera is to develop a digital video camera targeted mainly at observing star occultations, with the following attributes:

• precise GPS timestamp from integrated GPS receiver module
• highly sensitive monochrome image sensor
• price as low as possible

The development team consists of Stefan Meister and Andreas Schweizer.?

To reach the goal of a low price, we plan to initiate a Kickstarter campain later in 2019 so that components can be manufactured and bought at reasonable prices. In addition, as we develop the camera in our spare time, the time for R&D won't add to the camera price.

More information is available in the .

Project timeline

The current planning contains the following project phases:

• proof-of-concept (modification of an existing camera ASI120MM, by adding an external digital time inserter module) - completed
• prototype version 1 (standalone camera, based on an On Semi AR0130CSSM sensor) - completed
• firmware development and testing for prototype version 1 - ongoing
  • On the host side, we'd like to provide an ASCOM video driver for the camera.
  • It should be possible to save SER and ADV files, the latter with GPS timestamps in the metadata.
  • The control tool should be extended to support 16-bit ADV recording, histogram, dark frame subtraction
• Prototyp Version 2 (standalone camera, based on community feedback and experience with prototype version 1) - onging
  • Prototype V2 will be implemented in 2 phases because it contains a large number of new components (USB-C, microSD, new GPS module, RAM, new FPGA, RF switch and so on). Phase 1 consists of a bigger PCB with all components in place for easier debugging. In phase 2, the design will be adjusted and condensed.
• firmware development and testing for prototype version 2 - not started
• release candidate - not started
• kickstarter campain - not started

News

09.04.2019 Serial #3 of the prototype v1 camera is ready to use.

08.04.2019 includes an option to display 4 digits for the fraction of the second (100 microsecond resolution); requires .

06.03.2019 Streaming and previewing 16-bit video is working reliably now after fixing an issue with the Media Foundation COM integration.

04.03.2019 Support for writing FITS files (snapshots) has been implemented in the control tool. Writing ADV files is also working now, adding per-frame status metadata still needs to be implemented.

03.03.2019 Added a histogram view and bg/range slider control to the control app.

01.03.2019 The IMX428LLJ sensors have arrived!

01.03.2019 First ADV file generated from the control tool; some issues with brightness levels and an error at the end of the file.

26.02.2019 Two IMX428LLJ sensors are on the way to us.
