What is "BatteryLess Screwdriver"?
As the name implies, the BatteryLess Screwdriver is a screwdriver that does not require batteries. However, it does not require them not because I've achhieved a perpetum mobile, but because I removed them from the design.
I've had a screwdriver powered by batteries for many years. However, as time passed, the batteries started to lose their capacity and the screwdriver could only be used for 1 minute before it stopped working, after 1 hour of charging.
Since it's a cheap old model, no battery replacements exist for it. So I decided to remove the batteries and power it using the power supply used to charge the batteries.
