I would like to make an autonomous robot system with a charging simple, effective and safe for children.
And I imagined this: an AC adapter that I can plug a USB cable magnet (which is used to recharge the lamp P5R). Its magnetic end allows him to connect perfectly to the extremity of the lamp for recharging.
In your opinion:
- This system is viable? How can we improve?
- Is it possible to put a battery 9 or 12 volts (not 3.5 volt)? Which model do? Such a cable can be used?
What do you think?
