This time, I changed to a small mini car from a one-box used car which I purchased over 10 years ago.

In order to reduce the purchase cost, I ordered only the minimum necessary option, and for others I purchased by mail from the Amazon.com and removed the parts that were attached to the one-box car (the drive recorder, etc.) and decided to attach to the new mini-cars.

However, I really thought again,

"Optional costs may have been reasonable"

under the scorching sun, with doing

- finding the target 12V power supply (there are four types of 12V power supply in the car) and the earth terminal, from the panel of the centralized power supply unit in the car

- holding the LED light in my mouth, and holding a tester,

- shedding sweat like a waterfall, lying down on my body in a narrow car interior

However, we can love machines through these processes,

When I see just "boy" who could not disassemble and repair the device and could not make he AD / DA conversion circuit

with talking greatly about "IoT"

"Do not make me laugh"

I thought it seriously.
