Heathkit H2KTST HERO 2000 and Arm Trainer base Motor and Encoder tester - NEW

Description

This is a brand new H2KTST
Motor and Encoder tester for the Heathkit
HERO 2000 robot and Arm Trainer base.  It goes in the gripper for the optical encoders.
The H2KTST can help you identify and resolve issues with any of the motors and encoders used on the HERO 2000 robot arm and the base assembly including the torso and drive motors.  It allows you to easily move the motors to help remove an arm that needs service when it can't be homed.  This is a tool I use whenever working on or rebuilding a HERO 2000 arm and it saves a lot of time.  This would be great tool to keep on hand and
can help to get your robot running correctly again!
I've made small adapter cables to allow the tester to test Androbot TOPO and BOB motor/encoders as well as motors and encoders for other robots so this can be used the help test and service additional robots as well.
You just need to supply a 12V DC power source at the two pads labeled on the PCB.  The 12V powers the motor under test and is converted to 5V on board for the status LED's and to power the encoder assembly.  There are 5 LED's on the board.  The center is a RED/GREEN LED that lights up whenever the momentary switch is activated and the color reflects the polarity.  The smaller LED's will show the encoder and limit switch status.  When testing the gripper they show the state of both encoders.  The 10-pin connector will directly connect to any of the HERO 2000 motor cables where they would normally connect to the controller board.
You can find the manual for this online here:

Early versions were in a plastic housing that while nice added cost and isn't really required.  This isn't something you should need every day but when you do need to test or service the robot is extremely handy to have around.  I'd suggest just a regular 12V DC 1amp wall wart power supply.  You can also just use a 2-conductor cable with clips to connect to the 12V battery of the robot.  If you go that route I would add a diode inline to protect from reverse polarity.  The voltage drop from the diode will not affect the operation of the tester,
This is just the new tester board as pictured.  No robot or cables are included.
