Current hardware for TSC consists of
- a Raspberry Pi 3 Model B with 1 GByte RAM, Heatsinks might be a good idea as well, or a cooling fan
- a 16 GByte Micro SD card
- two Phidget 1067 stepper controllers
- two Power supplies - one sufficient for driving the stepper motors the other for the Pi
- the TSC HAT whose PCB can be found in the "Hardware" section of this repository. It includes an Arduino MIni Pro used as an Analog-Digital Converter for ST 4 and temperature measurement, an isolated connector for DSLR control, a USB/RS232 interface for LX200 operation and a battery - buffered realtime clock, the Adafruit DS3231.
Hardware can be bought from vendors like Conrad, Semaf, EXP-Tech, NoDNA, Phidgets.com, Pimoroni, SparkFun, AdaFruit or on EBay.
