== Features Of The Charger Adapter ==
The Charger Adapter replaces the old HERO Junior RT-1 AC Power Supply with a new, modern solution for Robot.

The main advantage of the Adapter is it utilizes a standard 5.5mm (2.1 x 5.5mm) plug for the DC connections.  This allows a standard Universal AC to DC Regulated Power Supply to be used unlike the original design.

The AC to DC Power Supply included with the Charger Adapter is 12v at 1 Amp.  It accepts universal AC input voltages and frequencies so it can work both domestically and internationally.  The 1 Amp rating also means the unit will operate cool and be under less stress which should allow long life.


== History ==
Mike Maginnis from Open Apple Podcast contacted Henry on August 8th, 2016 about possibly creating a new charger for his HERO Junior RT-1 robot.  Operational chargers are hard to find and no other options existed.  So Henry had an idea and went to work to design a replacement charger.

On September 8th, 2016 Mike Maginnis recorded a test of the HERO Junior RT-1 Charger Adapter connected to his Robot.  The Robot is fully powered and operational.
















== Pinouts ==
[[Image:IMG_20160828_152408-Fixed.png|thumb|upright=1|C146 4-Pin Connector Pinout]]
The 4-Pin Screw-Lock connector has numbers on the mating face (see pic).  With the "Key" or "Notch" facing up and the mating face toward you the pinout is:
*Top Left: Pin 4
*Top Right: Pin 1
*Bottom Left: Pin 3
*Bottom Right: Pin 2


Pins 1 and 4 '''TOP''' are connected together.  This tells the Robot that the Charger Adapter is connected.  Without this jumper the Robot can move around and possibly disconnect the Charger Adapter.
Pin 3 is DC Negative: Bottom '''LEFT''' as looking in to the FACE of the connector.
Pin 2 is DC Positive: Bottom '''RIGHT''' as looking in to the FACE of the connector.

The 5.5mm (2.1 x 5.5mm) DC Connector has DC Positive in the '''CENTER''' and DC Negative on the '''RING''' or outer connector.
