Day 9: A resistor tube man and a refrigerator robot

Friday, I continued my easy way with electronics. I was frustrated with my forever lacking of parts, or parts go missing, and my forever unstable connections that leave my final products (can I even call them so?) unstable.

In the meanwhile, I developed eyes for discarded toys sitting in the basement, old electronic devices are now treasures to be hunted and disassembled. Wednesday I dissected a dead mouse (the kind with wires, not the kind that poops by garbage cans); Friday I dissembled an race car.  With that, I gained 2 chips, a bunch of wheels, some gears, a motor, a remote control that can go backwards and forwards.

I decided to repurpose the wheels and the remote control for some home-made robot car, did not work.

I tried a bunch of other things, all failed ...

I decided to go very, very low bar and low tech. So I made the following: a resistor man and a refrige robot. The idea of the resistor man came from an intractable article. We piled a bunch of sea shells at his feet

A refrigerator robot made of magnets and leds.

Day 8: Dumb dumb ping pong pot

On Day 8, I felt my steam was out, more distracted than ever.  I happened to have a super busy day at work, sweating over a new language python. A breezy task such as sorting in JavaScript somehow became draconian struggle in Python.

Not just sorting. It was also a struggle with Django, with our code base. To my huge embarrassment I found myself modifying the wrong code block

...

At night, I watched a YouTube video on How to make a ping pong bot (then another one after that, then another, another.), so I made one myself.

Somewhere my wire connections were shaky, my bot ran about 10 secs, then went quiet.
