Boost converter testing beginning soon

A project log for WEFT electrovibration demo board

This board is for prototyping electrotactile interactions - use an electronic signal to dynamically change the texture of a surface.

Apologies for the lack of updates here - the project is most certainly still at the forefront of my attention, but I have been waylaid in the last month as I am changing jobs.

I will be taking Wednesday and Thursday to update this project, including some better documentation and project structure, as well as more verbose updates regarding the boost converter work.

I had OSHPark make a board (warning, board has not yet been validated by assembly/test) for prototyping the circuit described in the LM3478 application note here. My hope is to be able to tweak it with some component substitutions and get close to the values we'll need to make WEFT more reliable (the boost converter circuit will incorporate feedback, which is the main function missing from the current project).
