A HSDK for ultrasound imaging

After Murgen, which was a all-in-one analog acquiring and processing analog board for ultrasound imaging, we're glad to pursue the adventure of the black company, with the release of Tobo (the HV Pulser) as well as Goblin (TGC+ADC).

Tobo, the HV Pulser, connecting In and Out of the transducer. It includes the MD100 protection.

Goblin: it takes the signal coming back from Tobo, and processes it for it to reach the ADC, which is a 2Msps SPI.

These two boards, plus a 3.3/5V alim, a piezo and a controler (such as an arduino) are enough to do some basic imaging ! More on the Github repo here.

Building an OSH project takes time.. especially on documentation. What about we build it like any other program? Let's throw in the Readme.md as source files, let's compile them with python, pipe it to GraphViz... and bam ! Graphs and magic documentation happen !

Readme of the project here : https://github.com/kelu124/echomods/blob/master/Readme.md

The principles of the echOmods is to enable a full chain of ultrasound image processing and hardware control. Four basic modules are considered. Each of this module will be landing on a motherboard, more or less a stripboard.

Key interfaces, signals and alims will be available on each of the 19 tracks on the motherboard, and will enable communication between modules. However, some tracks can be unused by the modules.

In this dense version, there are 4 modules electronic modules, the Transducer and the Motor modules are not depicted.

These modules can have a form factor close to the arduino trinket pro, with a row of 19 pins on the side. Each module will have a function, as described below. At the heart of this project, there will be 4 modules, plus the motherboard. 2 of these modules will be SMD, 2 as modules based on stripboards. Two additional modules will enable replacing the transducer module and getting advanced signal acquisition/streaming, respectively
