Setup of hackeeng e moose. Logic analizer without a case because I hate male-female jumper wires for their unreliability. Soldering is our everything.

Some batch of bits running to&from mcu and sensor while sensor is connected to native Mrs. Mouse mcu. Yes, it's called "sniffing" in our world.

Software used is Saleae Logic. It's a good looking and responsive tool for sniffing and decoding low-level protocols. Here I have two-wire serial communication with 8-bit packets going in and out. First 8 bits going from mcu is an register's address. Second 8 bits is an answer from sensor.

This record contains 3 packets, first - for product id 1 (address 0x00), second - for product id 2 (address 0x01) and third (address 0x02) is a state (moving or not).

As a patient we have Oklick 645MW mouse with 2.4 ghz radio dongle. Price ~4$. I've bought it in our local Russian retailer. Sensor's chip has engraved number which is 3065.

After writing some lines of Arduino code I've transformed 2.4Mhz dongle mouse to working bluetooth monster! (without clicks, just for fun now 👌)

Let's check that comments are open.

Waiting for mine 🐬

Just got DPI setting working. Only three levels found by randomly getting and setting bits (I think there are special bits for other parameters, but I don't have documentation 😕)

First prototype in early stage wip...

But for now eating a birthday cake 🎂

After past night and day builds I've got this fancy proto-mouse.

- lipo battery with type-c charger
- OLED display for status
- buzzer feedback (also haptic in a plans)
- left, right and navigation buttons (+1 functional button)
- "in-hand" sensor (knows when you hold mouse in a hand)
- IR transmitter (needs IR receiver for recording signals) for turning your TV and PS off
- IMU sensor for air-mouse (for use with TV-sticks, etc.), also gestures in plans
- bright white LED for in-dark searchings
- 16 RGB LEDs at bottom because I can (cool, ha?)
- Bluetooth connection (this MCU doesn't support USB, will fix this later)

And yes, it doesn't have wheel right now (I don't have a space for it on this prototype-board). Also it needs a shell, will design it this week I guess.

First shapes... I like it 🍑

Still wip. Added some details. It's without mechanical things right now, just shell for grip experimenting. And after it will be successful I will design mechanical parts and split bodies.

This morning something will grow...

Hello, little

Will test ergonomics in office at Monday.
My rate is 6 of 10. Need improvements.

It's not very comfortable for a wrist. Navigation buttons must be closer to big finger. Horizontal scroll wheel in the left corner is inaccessible.

Got this amazing tool from my colleagues 🪛💎

Received XIAO BLE module. Starting to experiment. Also printed a new revision of shell with improved grip, moved navigation buttons and made a hole for horizontal scroll wheel.
