Chris wrote in to show off this interface he’s built for fine mouse control. he normally uses Dragon Naturally Speaking to control his mouse, but found it to have some issues. Sometimes it would crash, or simply be incapable of doing what he needed.
He ended up using an Arduino micro to make an IR receiver. Now he can use a simple remote control for fine movement in his mouse. As you can see in the video, it makes things like video editing much easier.
You can see all the details as well as download the code for this project on Chris’s web page.
