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.
Why
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.
How
Mouse Whisperer is based on the Micronucleos bootloader, which allows USB communication for both flashing and user code communication.
Provided code sample initializes board as USB mouse device and draws perfect circles until switched off. It will indicate status with built-in RGB led. You can switch it ON and OFF by simply touching the edge of the board.
Main features
- ATtiny85 MCU
- 8 KB Flash, 512B EEPROM, 512B SRAM
- WS2812E RGB addressable LED for status indication
- TTP223 based touch sensor for switching it ON and OFF
- Sandwich PCB design to protect important electronics from cats and children
How to use it
Mouse Whisperer comes preloaded with software. Simply insert it into USB socket, no drivers needed. Touch the edge of the board to switch it off, touch again to sswitch it back on.
If you wish to update software to your taste see information below.
Using Platformio and included sample firmware
Samples code in this repo provided as Platformio project, please follow the official Platformio installation guide first.
When a project is built using Platformio: Build task and ready to be flashed, run Platformio: Upload task. You insert your board into USB after that and the flashing process will start automatically. When done, code starts execution immediately.
Using Arduino
Please follow Digispark tutorial
Documentation
Jargon buster
Plain-language definitions for the technical terms used above.
- Bootloader
- Small starter software on a microcontroller that lets new code be uploaded before the main program runs. Knowing how to enter bootloader mode matters when you need to program the board or recover it after a faulty sketch.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
- SRAM
- Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.
