Single-board Computer

This is a Raspberry pi 3/4 or a Quartz64 computer with a standard 40-pin I/O connector. The basic installation steps are:

  • Install base OS (no user interface needed)
  • Create a user called tart sudo adduser tart
  • Enable the SPI interface (this is done using raspi_config on an rPi, and modprobe spi_rockchip on the Quartz64.

Install some packages​

The following packages are needed to continue with the install. Mostly this is docker.

sudo apt install curl docker.io docker-compose git sudo usermod -a -G tart docker

Install TailScale​

The TART single board computers are connected to a global network curl -fsSL https://tailscale.com/install.sh | sh sudo tailscale up

Install the TART operating software.​

This software contains the API server and the necessary code to communicate to the telescope electronics using the SPI interface.

git clone https://github.com/tart-telescope/sbc_code cd sbc_code/software docker-compose -f docker-compose-telescope.yml build

Connecting to your telescope locally​

If you telescope has an IP address on your network (i.e., x.x.x.x) then you can connect directly to it via a web browser

http://x.x.x.x

Troubleshooting​

You should see a web interface... If the image looks like a clock (showing the current time in UTC), then the TART can't communicate with it's correlator.
