Revision as of 09:02, 1 May 2017
The Minitiouner hardware is designed for easy home construction, uses only leaded components and consists of the 3 main components.
Whilst the project has previously used several tuner types and a version 1 PCB and adapter cards, new builders should only use the version 2 PCB described on this page and the Serit tuner described here.
To build the unit you only need to buy the following and then download the free MiniTioune software.
- The USB interface is available ready programmed from the MiniTiouner category in the BATC shop.
- The version 2 main PCB can be bought from the BATC shop after May 5th 2017.
- The Serit tuner or NIM covering 143 - 2450 MHz will be available from the BATC shop from early May 2017.
- The unit uses an MCP1826 1v regulator, which can be hard to find and is available from the BATC shop.
All other components such as Rs, Cs and 5v buck regulator are available from normal suppliers - see the parts list further down this page.
NOTE - due to different pinouts the previously available Sharp and Eardetek NIMs will NOT work with this board
Building the Version 2 MiniTiouner PCB
The PCB has been developed to fit snuggly inside a Hammond 1455 series 103x160x53mm enclosure - note both pictures show the beta board and the final board will be shorter and may fit inside the 120mm long box.
Parts list and schematic
More details to follow but the parts list and schematic can be downloaded:

The version 2 PCB with Serit tuner is the only available solution to receive and decode DVB-S2 reduced bandwidth modes (the version 1 PCB with adaptor card did as well) - this pictures show G0MJW recieving G8GTZ/p on 146 MHz using 16 APSK (approximately 1 mbit/s in 550 KHz bandwidth).
