Mouse Whisperer

What is it?

Mouse Whisperer is a small development kit that is based on Microchip ATtiny85 MCU. It will act like a physical mouse and draw perfect circles while you’re away.


There are many reasons why not, but also a few reasons why. Big Corpo tend to sell your convenience for security, don’t taking into account if you’re working in the office or from home.

  • I’m sick and tired entering passwords each time I leave laptop for 2 minutes
  • I don’t want my screen to go dark whenever I’m focused on something and happen to not move the mouse for a minute or two
  • I want to be available for other Team members, even if I went for a cup of coffee
  • But mainly, if someone enforce stupid policies on my laptop and I cannot change them – I will workaround them

Mouse Whisperer is there to bring some of that convenience back.
