A new toy arrived at GreenBean Towers recently:

This is an Amazon Dalian 1kg roaster. I have had my eye on this for some time and when Bella Barista decided to import them I could not resist and was the first to place an order for one early in January. Bella Barista have done a great job and the roaster finally arrived last week.
The first order of business was, of course, to convert it to full computer control of the heater and blower using RoastLogger:

I have just completed the first computer controlled roast:

I am delighted with the result although it will be some days until it will be ready for drinking. The BT readings are provided by a custom thermocouple I have installed and I have used the stock supplied thermocouple to provide the “ET” readings. It can be seen that this is not an ideal indication of ET as it indicates lower than BT towards the end of the roast which is not correct (BT is not falling, RoR is not negative). This is not a real concern as all control is based on BT. I may experiment with other locations for the ET thermocouple in future.
For anyone who is interested I have added many more photos including layout of the controller on
