AutoChanger - A Knitting Machine Auto Colour Changer to replace a Brother KRC-900
This project was designed to provide a lower cost replacement for the commercial auto colour changer available from Brother for their 1980's electronic knitting machines.
Bring your vintage Brother 950i back to life with an affordable, modern replacement for the original Brother KRC-900 auto colour changer. Designed by brain, built by hand, AutoChanger lets you automate colour changes on your knitting projects without hunting down a rare, decades-old commercial unit.
Fully open-source hardware and software. The complete design files, firmware, and build documentation are freely available if you want to understand exactly how it works or tinker further down the track.
You will need the arm from your KRC-900. The automatic changing functionality relies on the dual bed sinker plate.
You will also need your own USB-C cable.
Colours are random, if you request one specifically I will do my best but there are no guarantees.
These are printed, soldered, assembled, tested, sworn at, manipulated and tested in my shed. There is variation I can't help. Servos are the worst.
There is some weirdness with shipping to Germany so I've temporarily removed them. If you are in Germany and want to place an order, please send me a message and we can work though it.
You can read the operating instructions at: https://github.com/mage0r/AutoChanger/wiki/How-to-use-Firmware-Version-4.2
There's a live demo of the web interface at https://autochanger.mage0r.net/

Shipping policy
Doing my best, but shipping these days is hard.
If you are in the US, you may have to pay a Merchandise Processing Fee of $34. I just don't know anymore.
If you're in Europe, your local transport may charge more. I have heard of a lot of flat out rejections at customs. ---- Update: If you're in Germany, the customs agents are likely to take the shipping charge, spend a few weeks, then send it back to me. I've had to remove shipping to Germany from the list until it's resolved.
If you're in Australia, $12 Australian dollarydoos and if will be at your house by the weekend. I also accept dollarbucks from the younger audience.
