Sphero mini for Education and Entertainment

Finally Found Sphero mini from Continental Sim Lim tower for my kids birthday present and it cost S$78 which seems to be cheapest price I can get in Singapore. Sphero mini seems to be entertaining for my kids who are age 8 and 6 years old. It has drive mode to control Sphero mini, it can be a controller for the games and it can be programmed to follow the instructions to move and changing LED light as per preset.

Arriving Sim Lim tower after 3-4 years long break, bring back memories of working on school and work side projects. ?

1. Cable checker with LED light to check open/short with various cables types.?

2. Maze finder robot's chassis, motor, driver and its components.

3. Oscilloscope projects and its extension board.

4. Remote control switch with Infar red sensor.??

5. IR drop with Power rail scope, cable to attach to solder ball and self-made 50 ohm cable.
