OnStep controller system fully built

Onstep Controller fully operational $450
Includes Onstep Mini ver 1.274, using teensys 3.2
Has TMC2130 microstepping drivers

Full Wifi ( can hookup to andriod/ipad/Iphone etc
Has PEC control sensor is included
Has a physical limits input socket
RJ45 smart handcontroller socket
Full usb communication port.
All sockets are the standard XLR type from Jaycar 4 pin for steppers and 3 pin for PEC and Limits. Tha makes it easy for extenders where required.

There are 2 x 400 step stepper motors giving very high resolution
Included are 2 x 80 tooth pulleys and motor pulleys are 16 tooth, the rest is done by the configuration of controller according to your mount.

Also a gear that has a tiny magnet for a PEC sensor.

Now to qualify this system, it is currently configured for the Takahashi NJP temma2 mount. However through the brilliance of OnStep, you can configure this for any telescope mount even a home built one EQ or AZ.
Here is the link to the Wiki for OnStep.

reduction

Price reduced to $400
Just to add this is also good for a mount where the boards have failed, also you can use the original steppers so long as they are bipolar ones like the Skywatcher series etc.
Price for just controller less steppers is $300

To anyone interested in this controller I can say that Clive's electrical work is meticulous.
