Hand Held WiThrottle

This is a somewhat ergonomic case for a handheld model railway throttle which was designed by Peter Akers (flash62au on GitHub).

I designed the case for this in Fusion 360 using a new-to-me technique using a form which seems to have worked well for a case that fits nicely in the palm of my hand.

The components and code are all outlined in [GitHub](https://github.com/flash62au/WiTcontroller) and there is also a project page in the [DCC++ EX documentation](https://dcc-ex.com/throttles/witcontroller.html).

There is also a video of the throttle in action on [YouTube](https://youtu.be/RKnhfBCP_SQ).

It's important to note that there's no guarantee all components will be the same across the various different suppliers.

You will need M2 x 4mm self-tapping screws to assemble this.

The WeMos Lite LOLIN32, KY-040 rotary encoder, 0.96" OLED, and LiPo battery were all sourced from eBay locally in Australia, while the keypad in use for this was sourced from [Jaycar](https://www.jay
